- Background: Individuals with child maltreatment (CM) experiences show alterations in emotion recognition (ER). However, previous research has mainly focused on populations with specific mental disorders, which makes it unclear whether alterations in the recognition of facial expressions are related to CM, to the presence of mental disorders or to the combination of CM and mental disorders, and on ER of emotional, rather than neutral facial expressions. Moreover, commonly, recognition of static stimulus material was researched. Objective: We assessed recognition of dynamic (closer to real life) negative, positive and neutral facial expressions in individuals characterised by CM, rather than a specific mental disorder. Moreover, we assessed whether they show a negativity bias for neutral facial expressions and whether the presence of one or more mental disorders affects recognition. Methods: Ninety-eight adults with CM experiences (CM+) and 60 non-maltreated (CM-) adult controls watched 200 non-manipulated coloured video sequences, showing 20 neutral and 180 emotional facial expressions, and indicated whether they interpreted each expression as neutral or as one of eight emotions. Results: The CM+ showed significantly lower scores in the recognition of positive, negative and neutral facial expressions than the CM- group (p < .050). Furthermore, the CM+ group showed a negativity bias for neutral facial expressions (p < .001). When accounting for mental disorders, significant effects stayed consistent, except for the recognition of positive facial expressions: individuals from the CM+ group with but not without mental disorder scored lower than controls without mental disorder. Conclusions: CM might have long-lasting influences on the ER abilities of those affected. Future research should explore possible effects of ER alterations on everyday life, including implications of the negativity bias for neutral facial expressions on emotional wellbeing and relationship satisfaction, providing a basis for interventions that improve social functioning.

- BackgroundIndividuals with a history of child maltreatment (CM) are more often disliked, rejected and victimized compared to individuals without such experiences. However, contributing factors for these negative evaluations are so far unknown.ObjectiveBased on previous research on adults with borderline personality disorder (BPD), this preregistered study assessed whether negative evaluations of adults with CM experiences, in comparison to unexposed controls, are mediated by more negative and less positive facial affect display. Additionally, it was explored whether level of depression, severity of CM, social anxiety, social support, and rejection sensitivity have an influence on ratings.MethodsForty adults with CM experiences (CM +) and 40 non-maltreated (CM-) adults were filmed for measurement of affect display and rated in likeability, trustworthiness, and cooperativeness by 100 independent raters after zero-acquaintance (no interaction) and 17 raters after first-acquaintance (short conversation).ResultsThe CM + and the CM- group were neither evaluated significantly different, nor showed significant differences in affect display. Contrasting previous research, higher levels of BPD symptoms predicted higher likeability ratings (p = .046), while complex post-traumatic stress disorder symptoms had no influence on ratings.ConclusionsThe non-significant effects could be attributed to an insufficient number of participants, as our sample size allowed us to detect effects with medium effect sizes (f(2) = .16 for evaluation; f(2) = .17 for affect display) with a power of .95. Moreover, aspects such as the presence of mental disorders (e.g., BPD or post-traumatic stress disorder), might have a stronger impact than CM per se. Future research should thus further explore conditions (e.g., presence of specific mental disorders) under which individuals with CM are affected by negative evaluations as well as factors that contribute to negative evaluations and problems in social relationships.

- Background: Childhood maltreatment (CM) is frequently linked to interpersonal problemssuch as difficulties in social relationships, loneliness, and isolation. These difficulties mightpartly stem from troubles regulating comfortable interpersonal distance (CIPD).Objective: We experimentally investigated whether CM manifests in larger CIPD and whetherall subtypes of CM (i.e., physical, emotional, or sexual abuse and physical or emotional neglect)affect CIPD.Methods: Using the stop-distance method (i.e. a team member approached participants untilthe latter indicated discomfort), we assessed CIPD in 84 adults with a self-reported history ofCM (24 with depressive symptoms) and 57 adult controls without a history of CM (withoutdepressive symptoms).Results: Adults with CM showed a larger CIPD (Mdn = 86 cm) than controls (Mdn = 68 cm), andCIPD was largest for those with CM combined with current depressive symptoms (Mdn =145 cm) (p’s < .047). In the latter group, all subtypes of CM were associated with a largerCIPD compared to controls (p’s < .045). In the CM group without depressive symptoms, onlythose with emotional abuse (p = .040) showed a larger CIPD than controls.Conclusions: These results add to findings of differential socio-emotional long-termconsequences of CM, depending upon the subtype of CM. Future research should explorewhether a larger CIPD has a negative impact on social functioning in individuals exposed toCM, particularly in those with depressive symptoms.

- The phenomenon of physiological linkage describes similar fluctuations of two individuals' physiology, for example, the cardiac inter-beat interval (IBI). Physiological linkage is a well-documented occurrence in research settings of interacting dyads but the literature on non-interacting dyads, that is, someone watching a video of another person, is sparse. The current study investigated whether physiological linkage, based on IBI, occurs from watching videos where strangers report about personal (neutral, positive, negative non-traumatic, and negative traumatic) experiences. Videos were produced with six individuals and then presented to observers (N = 26). Time-frequency-domain cross-wavelet analyses supplemented by threshold-free cluster enhancement (TFCE; to account for multiple testing) showed significant physiological linkage between the IBI of observers and persons in the videos for 16 out of the 21 tested videos. Although significant physiological linkage also emerged for neutral videos and positive, negative valence videos led to such associations more reliably. This study shows that physiological linkage can be investigated in highly controlled conditions based on video stimuli paving the path for experimental manipulation in future research. Furthermore, due to the provision of information on time and frequency, the use of cross-wavelet analysis is encouraged to learn more about factors modulating physiological linkage. The current study presents the next step toward identifying psychophysiological causal and modulating factors of physiological linkage.
