A long-standing controversy in emotion research concerns the question whether stimuli must be conceptually interpreted, or semantically categorized, to evoke emotional reactions. According to the semantic primacy hypothesis, the answer to this question is positive; whereas according to the affective primacy hypothesis, it is negative: Emotions can also be, and perhaps often are, elicited by preconceptual stimulus representations, such as particular shapes or color patterns. In the present dissertation project, the semantic primacy hypothesis was tested in eight experiments using different latency judgment paradigms in which the perceptual latencies of object recognition and affect onset were measured and compared. The chronometric measurement methods comprised temporal judgments (temporal order judgments and simultaneity judgments: Publication A, Experiments 1–4; the rotating spot / rotating clock hand method: Publication B, Experiments 1–2) and speeded reaction time measurements (Publication C, Experiments 1–2). To elicit affective responses, pictures of pleasant (e.g., cats, children) and unpleasant objects (e.g., spiders, moldy food) from everyday life were presented. According to the semantic primacy hypothesis, object recognition is a necessary partial cause of affect. This implies the following three predictions that were tested in the studies: (1) Because causes must precede their effects, the time of the onset of object recognition must precede the time of the onset of affect. (2) The longer it takes a person to recognize an object, the longer it should also take them, other factors constant, to experience affect; therefore, the latencies of the two mental events should be positively correlated across individuals. (3) An experimental manipulation that delays the onset of object recognition (in this case a moderate blurring of the pictures) should also delay the onset of affect, and the effect of the manipulation on affect latency should be mediated by the delay in object recognition. In agreement with Prediction 1, regardless of the chronometric method used, the latency of object recognition consistently proved to be shorter than the latency of affect onset. According to the meta-analytically integrated latency differences estimated in the temporal judgment experiments, affect followed object recognition with a delay of 117 ms. This result was obtained for both pleasant and unpleasant stimuli and was independent of task order. Supporting Prediction 2, the latencies for object recognition and affect onset were positively correlated across participants (meta-analytic r = .50). Supporting Prediction 3, delaying object recognition by blurring the affective pictures was found to also delay the onset of affect and the effect of blurring on the latency of affect was found to be partly mediated by delayed object recognition. Two additional predictions tested and confirmed in Experiment C2 were: (4) False-coloring the affective pictures delays the onset of affect but not object recognition, and this effect is mediated by reduced affect intensity. (5) Judgments of the valence of the stimuli (i.e., whether the imaged object is pleasant or unpleasant) take more time than reports of object recognition, but less time than affect onset reports, for which valence judgments have often been used as a substitute in previous studies. Taken together, the results of the eight experiments provided consistent support for semantic primacy in the generation of pleasant and unpleasant feelings evoked by affective pictures: Object recognition can be considered a necessary partial cause of affect in the reported experiments. The results are compared to previous findings, possible reasons for deviant response patterns found in a small minority of the participants are considered, and several implications of the findings for emotion research are derived. Possible adaptations of the chronometric approach to investigate other questions of emotion research are suggested. Finally, limitations of the dissertation project are pointed out and possible ways to address these in future research are proposed.

Gefahrenlagen, wie schwere Unwetter, Terroranschläge oder die COVID-19-Pandemie, stellen aktuell und zukünftig eine Bedrohung unserer Gesellschaft dar. Im Fall dieser und weiterer Gefahren können Warnungen helfen, Schäden zu verhindern und Menschenleben zu retten, indem sie die Empfänger*innen informieren und Schutzmaßnahmen vermitteln. Das Protective Action Decision Model (PADM) (Lindell & Perry, 2012) bietet einen theoretischen Rahmen, der Verarbeitungsprozesse von Warnungen und die Entstehung von Schutzverhalten abbildet. Neben zahlreichen weiteren Elementen beinhaltet das PADM die Wahrnehmung von Risiko als zentralen Faktor. Im Sinne des Modells sowie bereits existierender Literatur wird Risikowahrnehmung jedoch häufig ausschließlich kognitiv abgebildet. Zudem untersuchen Studien vorwiegend einzelne Gefahrenlagentypen oder singuläre Ereignisse. Die vorliegende Arbeit bildet mit drei Beobachtungsstudien sowie einer experimentellen Studie Verarbeitungsprozesse von Warnungen vor verschiedenen Gefahrenlagen ab. Untersucht wurde der Einfluss der Warnungen auf kognitive und affektive Facetten der Risikowahrnehmung und ihre Rolle bei der Suche nach Informationen sowie der Intention, Schutzverhalten auszuführen. Über Online-Befragungen erhielten die Teilnehmenden Warnungen zu verschiedenen Gefahrenlagen (schweres Unwetter, Großbrand, extreme Gewalttat, Ausfall der Notrufnummer, Fund einer Weltkriegsbombe, COVID-19-Pandemie, Gewitter), die Informationen zur Gefahr sowie Handlungsempfehlungen enthielten. Befragt wurden sie unter anderem hinsichtlich ihrer Risikowahrnehmung vor und nach Warnerhalt sowie ihrer Intention, die angegebenen Schutzmaßnahmen zu befolgen oder sich Informationen zu suchen. Zudem wurden Eigenschaften der Warnungsempfänger*innen erhoben. Die Ergebnisse stärken die Rolle affektiver Risikowahrnehmung für die Verarbeitung von Warnungen sowie die Entstehung von Schutzverhalten und Informationssuche. Dies gilt jedoch nicht für alle Gefahrenlagen gleichermaßen, sodass der Einfluss von Eigenschaften der Gefahr, wie Häufigkeit oder Schweregrad, deutlich wird. Bezüglich der Eigenschaften der Empfänger*innen ergab sich ebenfalls kein einheitliches Bild. Basierend auf den Ergebnissen wird eine Erweiterung des PADM um ein Modellelement der affektiven Risikowahrnehmung vorgeschlagen. Fortführende Forschung zu Warnungen sollte eine multifacettierte Sichtweise von Risikowahrnehmung anstreben. Darüber hinaus sollten Gefahrenlagen vergleichend untersucht und ihre Eigenschaften sowie Eigenschaften der Warnungen systematisch variiert werden.

Abstract Background The need to optimize exposure treatments for anxiety disorders may be addressed by temporally intensified exposure sessions. Effects on symptom reduction and public health benefits should be examined across different anxiety disorders with comorbid conditions. Methods This multicenter randomized controlled trial compared two variants of prediction error‐based exposure therapy (PeEx) in various anxiety disorders (both 12 sessions + 2 booster sessions, 100 min/session): temporally intensified exposure (PeEx‐I) with exposure sessions condensed to 2 weeks (n = 358) and standard nonintensified exposure (PeEx‐S) with weekly exposure sessions (n = 368). Primary outcomes were anxiety symptoms (pre, post, and 6‐months follow‐up). Secondary outcomes were global severity (across sessions), quality of life, disability days, and comorbid depression. Results Both treatments resulted in substantial improvements at post (PeEx‐I: dwithin = 1.50, PeEx‐S: dwithin = 1.78) and follow‐up (PeEx‐I: dwithin = 2.34; PeEx‐S: dwithin = 2.03). Both groups showed formally equivalent symptom reduction at post and follow‐up. However, time until response during treatment was 32% shorter in PeEx‐I (median = 68 days) than PeEx‐S (108 days; TRPeEx‐I = 0.68). Interestingly, drop‐out rates were lower during intensified exposure. PeEx‐I was also superior in reducing disability days and improving quality of life at follow‐up without increasing relapse. Conclusions Both treatment variants focusing on the transdiagnostic exposure‐based violation of threat beliefs were effective in reducing symptom severity and disability in severe anxiety disorders. Temporally intensified exposure resulted in faster treatment response with substantial public health benefits and lower drop‐out during the exposure phase, without higher relapse. Clinicians can expect better or at least comparable outcomes when delivering exposure in a temporally intensified manner.

Body dissatisfaction is pervasive among young women in Western countries. Among the many forces that contribute to body dissatisfaction, the overrepresentation of thin bodies in visual media has received notable attention. In this study, we proposed that prevalence-induced concept change may be one of the cognitive mechanisms that explain how beauty standards shift. We conducted a preregistered online experiment with young women (N = 419) and found that when the prevalence of thin bodies in the environment increased, the concept of being overweight expanded to include bodies that would otherwise be judged as “normal.” Exploratory analyses revealed significant individual differences in sensitivity to this effect, in terms of women’s judgments about other bodies as well as their own. These results suggest that women’s judgments about other women’s bodies are biased by an overrepresentation of thinness and lend initial support to policies designed to increase size-inclusive representation in the media.

Zusammenfassung. Die Vereinbarkeit von Wissenschaft und Familie ist für Eltern im Allgemeinen und Frauen im Besonderen eine große Herausforderung. Tagungsteilnahmen sind wichtige Karrierebausteine und eine organisatorische Herausforderung für Eltern. In diesem Positionspapier wird ein Stimmungsbild zu familienfreundlicheren Kongressgestaltung in der Fachgruppe (FG) Klinische Psychologie und Psychotherapie der Deutschen Gesellschaft für Psychologie (DGPs) erfragt. 147 FG-Mitglieder (Rücklaufquote: 18.36 %) beantworteten Fragen zur Demographie, sowie Einstellungen gegenüber der FG-Tagung, Betreuungsmöglichkeiten und familienfreundlichen Maßnahmen. Von den Teilnehmenden waren 66 % Eltern, 45 % sagten wegen familiärer Verpflichtungen die FG-Tagung ab. Zusätzliche Kosten durch familiäre Verpflichtungen wurden als hoch eingeschätzt und familienfreundlichere Maßnahmen von vielen Teilnehmenden gewünscht. Familienfreundliche Konferenzen können ein klares Signal der Inklusion und Solidarität setzen und für die Aufrechterhaltung und Nachhaltigkeit wissenschaftlicher Kompetenz sorgen. Konkrete Empfehlungen für eine familienfreundliche Konferenzgestaltung werden als Checkliste im elektronischen Anhang zur Verfügung gestellt.

Given the increasing prevalence of chronic kidney disease (CKD) and its impact on health care, it is important to better understand the multiple factors influencing health-related quality of life (HRQOL), particularly since they have been shown to affect CKD outcomes. Determinants of HRQOL as measured by the validated Kidney Disease Quality of Life questionnaire (KDQOL) and the Patient Health Questionnaire depression screener (PHQ-9) were assessed in a routine CKD patient sample, the Greifswald Approach to Individualized Medicine (GANI_MED) renal cohort (N = 160), including a wide range of self-reported data, sociodemographic and laboratory measures. Compared to the general population, CKD patients had lower HRQOL indices. Dialysis was associated with (1) low levels of physical functioning, (2) increased impairments by symptoms and problems, and (3) more effects and burden of kidney disease. HRQOL is seriously affected in CKD patients. However, impairments were found irrespective of eGFR decline and albuminuria. Rather, the comorbid conditions of depression and diabetes predicted a lower HRQOL (physical component score). Further studies should address whether recognizing and treating depression may not only improve HRQOL but also promote survival and lower hospitalization rates of CKD patients.

Many orally dosed APIs are bioavailable only when formulated as an enteric dosage form to protect them from the harsh environment of the stomach. However, an enteric formulation is often accompanied with a higher development effort in the first place and the potential degradation of fragile APIs during the coating process. Ready-to-use enteric hard capsules would be an easily available alternative to test and develop APIs in enteric formulations, while decreasing the time and cost of process development. In this regard, Lonza Capsugel® Next Generation Enteric capsules offer a promising approach as functional capsules. The in vivo performance of these capsules was observed with two independent techniques (MRI and caffeine in saliva) in eight human volunteers. No disintegration or content release in the stomach was observed, even after highly variable individual gastric residence times (range 7.5 to 82.5 min), indicating the reliable enteric properties of these capsules. Seven capsules disintegrated in the distal part of the small intestine; one capsule showed an uncommonly fast intestinal transit (15 min) and disintegrated in the colon. The results for this latter capsule by MRI and caffeine appearance differed dramatically, whereas for all other capsules disintegrating in the small intestine, the results were very comparable, which highlights the necessity for reliable and complementary measurement methods. No correlation could be found between the gastric residence time and disintegration after gastric emptying, which confirms the robust enteric formulation of those capsules.

The COVID-19 pandemic is one of the most serious health and economic crises of the 21st century. From a psychological point of view, the COVID-19 pandemic and its consequences can be conceptualized as a multidimensional and potentially toxic stressor for mental health in the general population. This selective literature review provides an overview of longitudinal studies published until June 2021 that have investigated the impact of the COVID-19 pandemic on mental health in the European population. Risk and protective factors identified in the studies are summarized. Forty-two studies that met inclusion and search criteria (COVID-19, mental health, longitudinal, and Europe) in PubMed, PsycInfo, and Web of Science databases indicate differential effects of the pandemic on mental distress, depression, and anxiety, depending on samples and methods used. Age-specific (e.g., young age), social (e.g., female, ethnical minority, loneliness), as well as physical and mental health-related factors (e.g., pre-pandemic illness) were identified as risk factors for poor mental health. The studies point to several protective factors such as social support, higher cognitive ability, resilience, and self-efficacy. Increasing evidence supports the assumption of the pandemic being a multidimensional stressor on mental health, with some populations appearing more vulnerable than others, although inconsistencies arise. Whether the pandemic will lead to an increase in the prevalence of mental disorders is an open question. Further high-quality longitudinal and multi-national studies and meta-analyses are needed to draw the complete picture of the consequences of the pandemic on mental health.

Functional connectivity studies have demonstrated that creative thinking builds upon an interplay of multiple neural networks involving the cognitive control system. Theoretically, cognitive control has generally been discussed as the common basis underlying the positive relationship between creative thinking and intelligence. However, the literature still lacks a detailed investigation of the association patterns between cognitive control, the factors of creative thinking as measured by divergent thinking (DT) tasks, i.e., fluency and originality, and intelligence, both fluid and crystallized. In the present study, we explored these relationships at the behavioral and the neural level, based on N = 77 young adults. We focused on brain-signal complexity (BSC), parameterized by multi-scale entropy (MSE), as measured during a verbal DT and a cognitive control task. We demonstrated that MSE is a sensitive neural indicator of originality as well as inhibition. Then, we explore the relationships between MSE and factor scores indicating DT and intelligence. In a series of across-scalp analyses, we show that the overall MSE measured during a DT task, as well as MSE measured in cognitive control states, are associated with fluency and originality at specific scalp locations, but not with fluid and crystallized intelligence. The present explorative study broadens our understanding of the relationship between creative thinking, intelligence, and cognitive control from the perspective of BSC and has the potential to inspire future BSC-related theories of creative thinking.

Background: The worldwide population will grow older in the upcoming years. Aging, even in the absence of pathological processes, is associated with decline in cognitive functioning. Age-related cognitive decline is not a uniform process affecting every function in the same way. Research should thus examine specific functions, such as episodic memory or executive functions differentially, especially in older samples. Neural correlates of these functions are well characterized in young adults. However, research on functional and structural neural substrates underlying specific cognitive functions in older adults is scarce, but needed for example to identify targets for noninvasive interventions against cognitive decline. Current advances in this field point towards the effectiveness of combined noninvasive interventions of cognitive training and transcranial direct current stimulation (tDCS). So far, evidence regarding such combined interventions in older adults is inconclusive and neural mechanisms of successful interventions are still unclear. This line of research could advance the development of noninvasive methods to modulate cognitive functions and therefore address the unmet need for treatment options against age-related cognitive decline. Aims: The main aims of the present thesis were (i) to characterize functional and structural neural network correlates of two cognitive functions with high relevance for daily living, namely working memory updating and value-based decision making, (ii) to map out interventions of combined cognitive training and tDCS to modulate these cognitive functions in healthy older adults and adults with prodromal AD and (iii) to assess behavioral and neural outcomes of combined cognitive training (of either executive functions or visuo-spatial memory) and tDCS interventions. Methods: In order to address these aims, the present thesis includes five papers. Paper I assessed functional and structural neural correlates of working memory updating and value-based decision-making performance in healthy older adults using functional magnetic resonance imaging and diffusion tensor imaging. Papers II and III comprise study protocols of a three-week cognitive training of working memory updating and value-based decision-making abilities with concurrent tDCS over the left dorsolateral prefrontal cortex in healthy older adults and adults with prodromal AD. Paper IV used mixed-model analysis to compute behavioral outcomes of this combined intervention in healthy older adults, including outcome measures of the trained tasks, measures of transfer to untrained tasks and assessment of long-term effects at four weeks and half a year after the intervention. In paper V neural alterations after cognitive training of visuo-spatial memory and active stimulation compared to the training and sham (placebo) stimulation were assessed in older adults using measures of functional network centrality and diffusion tensor imaging-derived measures of grey matter microstructure. Results: Analyses revealed distinct functional and structural connectivity correlates of performance on the two cognitive tasks assessing working memory updating and value-based decision-making (paper I). Moreover, results showed a combined contribution of a specific white matter pathway (cingulum bundle) and frontoparietal functional connectivity to working memory updating performance, thereby providing information on possible network targets for modulation of working memory updating and value-based decision-making. The combined modulatory intervention of cognitive training and tDCS (papers II and IV) did not demonstrate group differences between concurrent active tDCS over sham tDCS in the trained tasks. However, analysis of a working memory transfer task revealed a beneficial effect of training and active tDCS over training and sham tDCS at post intervention and follow-up. Findings from paper V showed reduced functional network centrality after visuo-spatial memory training and active tDCS compared to training and sham tDCS in the stimulated brain area and its contralateral homologue. Additionally, after the training, measures of grey matter microstructural plasticity in the stimulated brain area were associated with beneficial training outcomes for the active but not the sham stimulation group. Conclusion: Taken together, cognitive performance, functional and structural networks as well as the possibility of their modulation through combined cognitive training and tDCS interventions were investigated in older adults with and without cognitive impairment. The present thesis therefore contributes to the field of noninvasive neuromodulation in older adults by characterizing distinct neural correlates of two age-sensitive executive functions, which may be altered through modulatory interventions. Moreover, the present work shows that cognitive training with concurrent tDCS holds the potential to elicit transfer effects to untrained tasks and further may evoke neural plasticity on the functional and microstructural level. This work thus promotes the development of modulatory interventions against age-associated cognitive decline and holds promising implications for translation to clinical application.

Introduction: While most people with cerebral palsy (CP) will have a life expectancy similar to that of the general population, international research has primarily focused on childhood and adolescence; and knowledge about the quality of life (QoL) of young adults with CP, its trajectories, and associated factors remains scarce. Methods: This longitudinal study included young adults with CP living in five European regions and who had previously participated in the SPARCLE cohort as children and/or adolescents. Their QoL in the psychological well-being and social relationships domains was estimated using age-appropriate validated instruments (KIDSCREEN-52 in childhood/adolescence and WHOQOL-Bref in young adulthood). We used generalized linear mixed-effect models with random intercept to estimate long-term trajectories of QoL in both domains and to investigate whether severity of impairment, pain, and seizure influenced these trajectories. We sought to identify potentially different trajectories of QoL from childhood to adulthood using a shape-based clustering method. Results: In total, 164 young adults with CP aged 22–27 years participated in the study. Psychological well-being linearly decreased by 0.78 points (scale 0–100) per year (95% confidence interval (CI) −0.99 to −0.56) from childhood to young adulthood, whereas QoL in the social relationships domain increased (β coefficient 1.24, 95% CI 0.92–1.55). Severity of impairment was associated with reduced QoL in all life periods of the study (childhood, adolescence, and young adulthood): motor impairment with social relationships, and more nuancedly intellectual disability with psychological well-being and social relationships. At all periods, frequent pain significantly reduced psychological well-being, and seizures were associated with lower QoL in the social relationships domain. In both domains, we identified a group of individuals with CP who presented a reverse trajectory compared with the general QoL trajectory. Conclusion: Identification of QoL trajectories and their associated factors yields improved knowledge about the experience of individuals with CP until young adulthood. Further studies are needed to better understand the determinants that have the greatest influence on the different shapes of long-term trajectories of QoL.

Moral rules are a cornerstone of many societies. Most moral rules are concerned with the welfare of other individuals, reflecting individuals’ innate aversion against harming other individuals. Harming others is associated with aversive experiences, implying that individuals who are sensitive to the aversiveness of these experiences are more likely to follow moral rules than individuals who are insensitive to the aversiveness of these experiences. Individuals’ sensitivity for aversive experiences depends on individuals’ ability to integrate the underlying neural and physiological processes: Individuals who are more efficient in integrating these processes are more sensitive to the aversiveness that is associated with moral rule violations than individuals who are less efficient in integrating these processes. Individuals who differ in their ability to integrate these processes may, thus, also differ in their inclination to follow moral rules. We tested this assumption in a sample of healthy individuals (67 males) who completed measures of moral rule adherence and integration abilities. Moral rule adherence was assessed with self-report measure and integration abilities were assessed with a resting state measure of heart rate variability (HRV), which reflects prefrontal–(para-)limbic engagement during the integration of physical and neural processes. We found a positive association between individuals’ HRV and individuals’ moral rule adherence, implying that individuals with efficient integration abilities were more inclined to follow moral rules than individuals with inefficient integration abilities. Our findings support the assumption that individuals with different integration abilities also differ in moral rule adherence, presumably because of differences in aversiveness sensitivity.

Zusammenfassung. Die Klinische Psychologie ist essentieller Bestandteil interdisziplinärer Forschung im Bereich psychischer Störungen. Ziel der präsentierten Analyse war es, den individuellen Beitrag der Psychologie abzubilden. Wir bestimmten daher objektive Indikatoren für die Mitwirkung der deutschsprachigen Klinischen Psychologie und ihrer psychologischen Nachbardisziplinen an den Forschungsthemen zu psychischen Störungen. Eine themenbezogene Drittmittelanalyse für den Zeitraum 2000 – 2018 identifizierte 85 Großprojekte unter klinisch-psychologischer Leitung sowie 10 Personenförderungen mit einem Gesamtfördervolumen von 156 Millionen Euro. Weiterhin zeigte eine Publikationsanalyse, dass in den Jahren 1980 – 2018 die 150 deutschsprachigen Autor_innen mit den meisten themenrelevanten Publikationen mehrheitlich (63 %) einen akademischen Abschluss in Psychologie hatten. Die Anzahl der Publikationen nahm unter den psychologischen Autor_innen insgesamt jährlich zu. Wir identifizierten ein breites Forschungsfeld in störungsspezifischer, verfahrensspezifischer und neurowissenschaftlich fundierter Forschung. Die Ergebnisse verdeutlichen den substantiellen Beitrag der Psychologie in der Grundlagen- und Behandlungsforschung zu psychischen Störungen.

Background: Depression is a highly prevalent mental disorder, but only a fraction of those affected receive evidence-based treatments. Recently, Internet-based interventions were introduced as an efficacious and cost-effective approach. However, even though depression is a heterogenous construct, effects of treatments have mostly been determined using aggregated symptom scores. This carries the risk of concealing important effects and working mechanisms of those treatments. Methods: In this study, we analyze outcome and long-term follow-up data from the EVIDENT study, a large (N = 1,013) randomized-controlled trial comparing an Internet intervention for depression (Deprexis) with care as usual. We use Network Intervention Analysis to examine the symptom-specific effects of the intervention. Using data from intermediary and long-term assessments that have been conducted over 36 months, we intend to reveal how the treatment effects unfold sequentially and are maintained. Results: Item-level analysis showed that scale-level effects can be explained by small item-level effects on most depressive symptoms at all points of assessment. Higher scores on these items at baseline predicted overall symptom reduction throughout the whole assessment period. Network intervention analysis offered insights into potential working mechanisms: while deprexis directly affected certain symptoms of depression (e.g., worthlessness and fatigue) and certain aspects of the quality of life (e.g., overall impairment through emotional problems), other domains were affected indirectly (e.g., depressed mood and concentration as well as activity level). The configuration of direct and indirect effects replicates previous findings from another study examining the same intervention. Conclusions: Internet interventions for depression are not only effective in the short term, but also exert long-term effects. Their effects are likely to affect only a small subset of problems. Patients reporting these problems are likely to benefit more from the intervention. Future studies on online interventions should examine symptom-specific effects as they potentially reveal the potential of treatment tailoring.

Over the last decades, various predictors have proven relevant for job performance [e.g., general mental ability (GMA), broad personality traits, such as the Big Five]. However, prediction of job performance is far from perfect, and further potentially relevant predictors need to be investigated. Narrower personality traits, such as individuals' character strengths, have emerged as meaningfully related to different aspects of job performance. However, it is still unclear whether character strengths can explain additional variance in job performance over and above already known powerful predictors. Consequently, the present study aimed at (1) examining the incremental validity of character strengths as predictors of job performance beyond GMA and/or the Big Five traits and (2) identifying the most important predictors of job performance out of the 24 character strengths, GMA, and the Big Five. Job performance was operationalized with multidimensional measures of both productive and counterproductive work behavior. A sample of 169 employees from different occupations completed web-based self-assessments on character strengths, GMA, and the Big Five. Additionally, the employees' supervisors provided web-based ratings of their job performance. Results showed that character strengths incrementally predicted job performance beyond GMA, the Big Five, or GMA plus the Big Five; explained variance increased up to 54.8, 43.1, and 38.4%, respectively, depending on the dimension of job performance. Exploratory relative weight analyses revealed that for each of the dimensions of job performance, at least one character strength explained a numerically higher amount of variance than GMA and the Big Five, except for individual task proactivity, where GMA exhibited the numerically highest amount of explained variance. The present study shows that character strengths are relevant predictors of job performance in addition to GMA and other conceptualizations of personality (i.e., the Big Five). This also highlights the role of socio-emotional skills, such as character strengths, for the understanding of performance outcomes above and beyond cognitive ability.

Körpersignale sind elementar für die Aufrechterhaltung der Homöostase, um eine angemessene Regulation der Körperfunktionen zu ermöglichen und dadurch das Überleben des Individuums sicherzustellen. Die bisherige Forschung hat die dysfunktionale Wahrnehmung dieser interozeptiven Signale als wichtigen Bestandteil vieler Angst- und Gesundheitsprobleme identifiziert, da selbst leichte und harmlose Körperempfindungen eine übermäßig starke Mobilisierung von Abwehrreaktionen hervorrufen können. Obwohl das wissenschaftliche Interesse im Bereich Interozeption in den letzten Jahren stark gewachsen ist, wurde die Dynamik von Abwehrreaktionen als Reaktion auf Körpersignale bisher selten untersucht. Daher hatte die vorliegende Arbeit zum Ziel, die verhaltensbezogene und psychophysiologische Dynamik der defensiven Mobilisierung auf bedrohliche interozeptive Signale sowie den moderierenden Effekt von Dispositionsfaktoren und biologisch determinierten Verhaltensmarkern zu untersuchen. In der ersten Studie wurden die Dynamik defensiver Mobilisierung auf eine näher-kommende externe Bedrohung mit einer sich annähernden interozeptiven respiratorischen Bedrohung, in Abhängigkeit von der Bedrohungsnähe und der Möglichkeit zur Vermeidung, bezüglich subjektiver, autonomer und respiratorische Reaktionen sowie Gehirnreaktionen und defensiver Reflexe verglichen. In der zweiten Studie wurde die Mobilisierung defensiver Reaktionen während der wiederholten Vermeidung von kulminierender Atemnot analysiert, um eine detaillierte Analyse der Initiierung und Aufrechterhaltung von aktiven Vermeidungsverhalten zu erhalten. Die dritte Studie unterweiterte die diese Befunde, indem die Rolle der maximalen freiwilligen Luftanhaltezeit als möglicher Prädiktor für eine übermäßig starke Mobilisierung defensiver Reaktionen bei der Konfrontation mit einer näherkommenden respiratorischen Bedrohung, in Abhängigkeit der Möglichkeit zur Vermeidung, untersucht wurde. In der vierten Studie wurden die Prädiktoren für aktives Abwehrverhalten (d.h., Flucht oder aktive Vermeidung bei Konfrontation) während ansteigender Atemnot, induziert durch in der Intensität ansteigende inspiratorische Atemwiderstände gefolgt von einer kurzen Blockade der Einatmung, untersucht. Die erste Studie zeigte, dass das defensive Aktivierungsmuster bei der Mobilisierung defensiver Reaktionen auf eine sich annähernde externe Bedrohung annähernd vergleichbar ist wie bei einer interozeptiven respiratorischen Bedrohung, unabhängig von der Möglichkeit zur Vermeidung. Zusätzlich wurde eine bedrohungsspezifische Mobilisierung des respiratorischen Systems bei der Konfrontation mit der unvermeidbaren interozeptiven Bedrohung beobachtet. Die Daten der zweiten Studie demonstrierten, dass die Initiierung von erstmaligen Vermeidungsverhalten als Reaktion auf ansteigende Atemnot begleitet wird von physiologischen Erregungen als Indikatoren für eine Reaktionsvorbereitung. Diese verschwanden zunehmend mit wiederholter Vermeidung, was auf die Entwicklung von gewohnheitsmäßiger Vermeidung hindeutet. Darüber hinaus wurde in der dritten Studie gezeigt, dass eine übermäßig starke Mobilisierung von Abwehrreaktionen auf eine sich annähernde unvermeidbare respiratorische Bedrohung durch eine reduzierte maximale freiwillige Luftanhaltezeit vorhergesagt wird, jedoch nicht, wenn die Möglichkeit zur Vermeidung vorhanden war. Die vierte Studie demonstrierte, dass eine höhere Angstempfindlichkeit und eine kürzere freiwillige maximale Luftanhaltezeit mit aktivem Vermeidungsverhalten während ansteigender Atemnot assoziiert sind. Zusammenfassend zeigen die vorliegenden Daten, dass die defensive Mobilisierung für eine exterozeptive Bedrohung vergleichbar ist wie für eine interozeptive Bedrohung und sich in Abhängigkeit der Bedrohungsnähe und dem verfügbarem Abwehrrepertoire ändert. Darüber hinaus ist die Neigung, Erregungsgefühle zu befürchten und eine verminderte Belastungstoleranz während freiwilligem Luftanhaltens mit einer erhöhten Angst- und Furchtreaktion auf Atemnotsymptome verbunden. Daher könnten diese dispositionellen und biologischen Verhaltensmarker bei der Konfrontation mit ansteigender Atemnot aktives Vermeidungsverhalten begünstigen und, wenn sie gewohnheitsmäßig ausgeführt werden, kann sich persistentes Vermeidungsverhalten entwickeln, welches das Risiko für die Entstehung einer ernsthaften psychischen Erkrankung erhöht.

Abstract In crisis communication, warning messages are key to prevent or mitigate damage by informing the public about impending risks and hazards. The present study explored the influence of hazard type, trait anxiety, and warning message on different components of risk perception. A survey examined 614 German participants (18–96 years, M = 31.64, 63.0% female) using a pre–post comparison. Participants were randomly allocated to one of five hazards (severe weather, act of violence, breakdown of emergency number, discovery of a World War II bomb, or major fire) for which they received a warning message. Four components of risk perception (perceived severity, anticipatory worry, anticipated emotions, and perceived likelihood) were measured before and after the receipt. Also, trait anxiety was assessed. Analyses of covariance of risk perception were calculated, examining the effect of warning message, trait anxiety, and hazard type while controlling for age, gender, and previous hazard experience. Results showed main effects of hazard type and trait anxiety on every component of risk perception, except for perceived likelihood. The receipt of a warning message led to a significant decrease in anticipated negative emotions. However, changes across components of risk perception, as well as hazards, were inconsistent, as perceived severity decreased while perceived likelihood and anticipatory worry increased. In addition, three interactional effects were found (perceived severity × hazard type, perceived severity × trait anxiety, and anticipated emotions × hazard type). The findings point toward differences in the processing of warning messages yet underline the importance of hazard type, as well as characteristics of the recipient.

Our emotional experiences depend on our interoceptive ability to perceive and interpret changes in our autonomous nervous system. An inaccurate perception and interpretation of autonomic changes impairs our ability to understand and regulate our emotional reactions. Impairments in emotion understanding and emotion regulation increase our risk for mental disorders, indicating that interoceptive deficits play an important role in the etiology and pathogenesis of mental disorders. We, thus, need measures to identify those of us whose interoceptive deficits impair their emotion understanding and emotion regulation. Here, we used cardiac measures to investigate how our ability to engage prefrontal and (para-)limbic brain region regions affects our ability to perceive and interpret cardiac changes. We administered a heartbeat detection task to a sample of healthy individuals (n = 113) whose prefrontal-(para-) limbic engagement had been determined on basis of a heart rate variability recording. We found a positive association between heartbeat detection and heart rate variability, implying that individuals with higher heart rate variability were more accurate in heartbeat detection than individuals with lower heart rate variability. These findings suggest that our interoceptive accuracy depends on our prefrontal-(para-)limbic engagement during the perception and interpretation of cardiac changes. Our findings also show that cardiac measures may be useful to investigate the association between interoceptive accuracy and prefrontal-(para-)limbic engagement in a time- and cost-efficient manner.

Over the last years, there has been a resurge in the interest to study the relationship between interoception and emotion. By now, it is well established that interoception contributes to the experience of emotions. However, it may also be possible that interoception contributes to the regulation of emotions. To test this possibility, we studied the relationship between interoception and emotion regulation in a sample of healthy individuals (n = 84). We used a similar heartbeat detection task and a similar self-report questionnaire for the assessment of interoceptive accuracy and emotion regulation as in previous studies. In contrast to previous studies, we differentiated between male and female individuals in our analyses and controlled our analyses for individual characteristics that may affect the relationship between interoceptive accuracy and emotion regulation. We found sex-differences in interoceptive accuracy and emotion regulation that amounted to a sex-specific relationship between interoceptive accuracy and emotion regulation: Whereas interoceptive accuracy was related to reappraisal but not to suppression in male individuals, interoceptive accuracy was unrelated to reappraisal and suppression in female individuals. These findings indicate that the relationship between interoception and emotion regulation is far more complex than has been suggested by previous findings. However, these findings nonetheless support the view that interoception is essential for both, the regulation and experience of emotions.

Much research has been devoted to the development of emotion recognition tests that can be used to investigate how individuals identify and discriminate emotional expressions of other individuals. One of the most prominent emotion recognition tests is the Reading the Mind in the Eyes Test (RME-T). The original RME-T has been widely used to investigate how individuals recognize complex emotional expressions from the eye region of adult faces. However, the RME-T can only be used to investigate inter-individual differences in complex emotion recognition during the processing of adult faces. To extend its usefulness, we developed a modified version of the RME-T, the Reading the Mind in the Eyes of Children Test (RME-C-T). The RME-C-T can be used to investigate how individuals recognize complex emotional expressions from the eye region of child faces. However, the validity of the RME-C-T has not been evaluated yet. We, thus, administered the RME-C-T together with the RME-T to a sample of healthy adult participants (n = 119). The Interpersonal Reactivity Index (IRI) and the Toronto Alexithymia Scale (TAS) were also administered. Participants’ RME-C-T performance correlated with participants’ RME-T performance, implying that the RME-C-T measures similar emotion recognition abilities as the RME-T. Participants’ RME-C-T performance also correlated with participants’ IRI and TAS scores, indicating that these emotion recognition abilities are affected by empathetic and alexithymic traits. Moreover, participants’ RME-C-T performance differed between participants with high and low TAS scores, suggesting that the RME-C-T is sensitive enough to detect impairments in these emotion recognition abilities. The RME-C-T, thus, turned out to be a valid measure of inter-individual differences in complex emotion recognition during the processing of child faces.

In the present study, we investigated whether inter-individual differences in vagally mediated heart rate variability (vmHRV) would be associated with inter-individual differences in empathy and alexithymia. To this end, we determined resting state HF-HRV in 90 individuals that also completed questionnaires assessing inter-individual differences in empathy and alexithymia. Our categorical and dimensional analyses revealed that inter-individual differences in HF-HRV were differently associated with inter-individual differences in empathy and alexithymia. We found that individuals with high HF-HRV reported more empathy and less alexithymia than individuals with low HF-HRV. Moreover, we even found that an increase in HF-HRV was associated with an increase in empathy and a decrease in alexithymia across all participants. Taken together, these findings indicate that individuals with high HF-HRV are more empathetic and less alexithymic than individuals with low HF-HRV. These differences in empathy and alexithymia may explain why individuals with high HF-HRV are more successful in sharing and understanding the mental and emotional states of others than individuals with low HF-HRV.

Increasing evidence suggests that cognitive-control processes can be configured to optimize either persistence of information processing (by amplifying competition between decision-making alternatives and top-down biasing of this competition) or flexibility (by dampening competition and biasing). We investigated whether high-frequency binaural beats, an auditory illusion suspected to act as a cognitive enhancer, have an impact on cognitive-control configuration. We hypothesized that binaural beats in the gamma range bias the cognitive-control style toward flexibility, which in turn should increase the crosstalk between tasks in a dual-task paradigm. We replicated earlier findings that the reaction time in the first-performed task is sensitive to the compatibility between the responses in the first and the second task—an indication of crosstalk. As predicted, exposing participants to binaural beats in the gamma range increased this effect as compared to a control condition in which participants were exposed to a continuous tone of 340 Hz. These findings provide converging evidence that the cognitive-control style can be systematically biased by inducing particular internal states; that high-frequency binaural beats bias the control style toward more flexibility; and that different styles are implemented by changing the strength of local competition and top-down bias.
