A revised instrument for the assessment of empathy and Theory of Mind in adolescents: Introducing the EmpaToM-Y
Empathy and Theory of Mind (ToM) are two core components of social understanding. The EmpaToM is a validated social video task that allows for independent manipulation and assessment of the two capacities. First applications revealed that empathy and ToM are dissociable constructs on a neuronal as well as on a behavioral level. As the EmpaToM has been designed for the assessment of social understanding in adults, it has a high degree of complexity and comprises topics that are inadequate for minors. For this reason, we designed a new version of the EmpaToM that is especially suited to measure empathy and ToM in youths. In experiment 1, we successfully validated the EmpaToM-Y on the original EmpaToM in an adult sample (N = 61), revealing a similar pattern of results across tasks and strong correlations of all constructs. As intended, the performance measure for ToM and the control condition of the EmpaToM-Y showed reduced difficulty. In experiment 2, we tested the feasibility of the EmpaToM-Y in a group of teenagers (N = 36). Results indicate a reliable empathy induction and higher demands of ToM questions for adolescents. We provide a promising task for future research targeting inter-individual variability of socio-cognitive and socio-affective capacities as well as their precursors and outcomes in healthy minors and clinical populations
Worry is associated with robust reductions in heart rate variability: a transdiagnostic study of anxiety psychopathology
Background
Individuals with anxiety disorders display reduced resting-state heart rate variability (HRV), although findings have been contradictory and the role of specific symptoms has been less clear. It is possible that HRV reductions may transcend diagnostic categories, consistent with dimensional-trait models of psychopathology. Here we investigated whether anxiety disorders or symptoms of anxiety, stress, worry and depression are more strongly associated with resting-state HRV.
Methods
Resting-state HRV was calculated in participants with clinical anxiety (n = 25) and healthy controls (n = 58). Symptom severity measures of worry, anxiety, stress, and depression were also collected from participants, regardless of diagnosis.
Results
Participants who fulfilled DSM-IV criteria for an anxiety disorder displayed diminished HRV, a difference at trend level significance (p = .1, Hedgesâ g = -.37, BF10 = .84). High worriers (Total n = 41; n = 22 diagnosed with an anxiety disorder and n = 19 not meeting criteria for any psychopathology) displayed a robust reduction in resting state HRV relative to low worriers (p = .001, Hedgesâ g = -.75, BF10 = 28.16).
Conclusions
The specific symptom of worry â not the diagnosis of an anxiety disorder â was associated with the most robust reductions in HRV, indicating that HRV may provide a transdiagnostic biomarker of worry. These results enhance understanding of the relationship between the cardiac autonomic nervous system and anxiety psychopathology, providing support for dimensional-trait models consistent with the Research Domain Criteria framework
Verbal instructions override the meaning of facial expressions
Psychological research has long acknowledged that facial expressions can implicitly trigger affective
psychophysiological responses. However, whether verbal information can alter the meaning of facial
emotions and corresponding response patterns has not been tested. This study examined emotional
facial expressions as cues for instructed threat-of-shock or safety, with a focus on defensive responding.
In addition, reversal instructions were introduced to test the impact of explicit safety instructions on
fear extinction. Forty participants were instructed that they would receive unpleasant electric shocks,
for instance, when viewing happy but not angry faces. In a second block, instructions were reversed
(e.g., now angry faces cued shock). Happy, neutral, and angry faces were repeatedly presented, and
auditory startle probes were delivered in half of the trials. The defensive startle reflex was potentiated
for threat compared to safety cues. Importantly, this effect occurred regardless of whether threat
was cued by happy or angry expressions. Although the typical pattern of response habituation was
observed, defense activation to newly instructed threat cues remained significantly enhanced in the
second part of the experiment, and it was more pronounced in more socially anxious participants.
Thus, anxious individuals did not exhibit more pronounced defense activation compared to less anxious
participants, but their defense activation was more persistent
The degree of safety behaviors to a safety stimulus predicts development of threat beliefs
Safety behaviors are behavioral responses that aim to prevent or minimize an imminent threat when confronting a feared stimulus. Despite its adaptive purpose, preliminary evidence suggests that unnecessary safety behaviors to a safety stimulus induce threat beliefs to it. By allowing participants to engage in safety behaviors dimensionally, this study tested whether the degree of safety behaviors to a safety stimulus predicts the subsequent level of threat expectancies to it. To this end, participants first acquired safety behaviors to a threat-related stimulus (A). Safety behaviors then became available only for one safety stimulus (C), but not to another safety stimulus (B). After engaging in safety behaviors to C, participants exhibited greater threat expectancies to C compared to B, albeit with a small effect size. Importantly, the degree of safety behaviors predicted an increase in threat expectancies. The current findings suggest that safety behaviors to safety stimuli are linked to the development of threat beliefs.</p
Donât look at me like that: Integration of gaze direction and facial expression
Public Significance Statement This study highlights flexible and emotion-specific temporal aspects of gaze and face information integration processes that are involved in social perception and attention. The findings strengthen the approach-avoidance congruency hypothesis with an integration of gaze and face information at early processing stages. Efficient decoding of facial expressions and gaze direction supports reactions to social environments. Although both cues are processed fast and accurately, when and how these cues are integrated is still debated. We investigated the temporal integration of gaze and emotion cues. Participants responded to letters that were randomly presented on four faces. Two of these faces initially showed direct gaze, two showed averted gaze. Upon target presentation, two faces changed gaze direction (from averted to direct and vice versa). Simultaneously, facial expressions changed from neutral to either an approach- or an avoidance-oriented emotion expression (Experiment 1a: angry/fearful; Experiment 1b: happy/disgusted). Although angry and fearful expressions diminished any effects of gaze direction (Experiment 1a), a direct gaze advantage was found for happy and an averted gaze advantage for disgusted faces (Experiment 1b). This pattern is consistent with hypotheses suggesting a processing benefit when emotion expression and gaze information are congruent in terms of approach- or avoidance-orientation. In Experiment 2, we tracked eye movements and, again, found evidence for an approach-avoidance-congruency advantage for happy and disgusted faces both in performance and gaze behavior. Gaze behavior analyses suggested an integration of gaze and emotion information that was already visible from 300 ms after target onset

Mapping Research Domain Criteria using a transdiagnostic mini-RDoC assessment in mental disorders: a confirmatory factor analysis
This study aimed to build on the relationship of well-established self-report and behavioral assessments to the latent constructs positive (PVS) and negative valence systems (NVS), cognitive systems (CS), and social processes (SP) of the Research Domain Criteria (RDoC) framework in a large transnosological population which cuts across DSM/ICD-10 disorder criteria categories. One thousand four hundred and thirty one participants (42.1% suffering from anxiety/fear-related, 18.2% from depressive, 7.9% from schizophrenia spectrum, 7.5% from bipolar, 3.4% from autism spectrum, 2.2% from other disorders, 18.4% healthy controls, and 0.2% with no diagnosis specified) recruited in studies within the German research network for mental disorders for the Phenotypic, Diagnostic and Clinical Domain Assessment Network Germany (PD-CAN) were examined with a Mini-RDoC-Assessment including behavioral and self-report measures. The respective data was analyzed with confirmatory factor analysis (CFA) to delineate the underlying latent RDoC-structure. A revised four-factor model reflecting the core domains positive and negative valence systems as well as cognitive systems and social processes showed a good fit across this sample and showed significantly better fit compared to a one factor solution. The connections between the domains PVS, NVS and SP could be substantiated, indicating a universal latent structure spanning across known nosological entities. This study is the first to give an impression on the latent structure and intercorrelations between four core Research Domain Criteria in a transnosological sample. We emphasize the possibility of using already existing and well validated self-report and behavioral measurements to capture aspects of the latent structure informed by the RDoC matrix
Sometimes I feel the fear of uncertainty: How intolerance of uncertainty and trait anxiety impact fear acquisition, extinction and the return of fear
It is hypothesized that the ability to discriminate between threat and safety is impaired in individuals with high dispositional negativity, resulting in maladaptive behavior. A large body of research investigated differential learning during fear conditioning and extinction protocols depending on individual differences in intolerance of uncertainty (IU) and trait anxiety (TA), two closely-related dimensions of dispositional negativity, with heterogenous results. These might be due to varying degrees of induced threat/safety uncertainty. Here, we compared two groups with high vs. low IU/TA during periods of low (instructed fear acquisition) and high levels of uncertainty (delayed non-instructed extinction training and reinstatement). Dependent variables comprised subjective (US expectancy, valence, arousal), psychophysiological (skin conductance response, SCR, and startle blink), and neural (fMRI BOLD) measures of threat responding. During fear acquisition, we found strong threat/safety discrimination for both groups. During early extinction (high uncertainty), the low IU/TA group showed an increased physiological response to the safety signal, resulting in a lack of CS discrimination. In contrast, the high IU/TA group showed strong initial threat/safety discrimination in physiology, lacking discriminative learning on startle, and reduced neural activation in regions linked to threat/safety processing throughout extinction training indicating sustained but non-adaptive and rigid responding. Similar neural patterns were found after the reinstatement test. Taken together, we provide evidence that high dispositional negativity, as indicated here by IU and TA, is associated with greater responding to threat cues during the beginning of delayed extinction, and, thus, demonstrates altered learning patterns under changing environments.
