Show moreThis study investigates whether there exist differences in facial emotion detection accuracy in patients suffering from Vestibular Schwannoma (VS) due to their facial paresis. Forty-four VS patients, half of them with, and half of them without a facial paresis, had to classify pictures of facial expressions as being emotional or non-emotional. The visual information of images was systematically manipulated by adding different levels of visual noise. The study had a mixed design with emotional expression (happy vs. angry) and visual noise level (10% to 80%) as repeated measures and facial paresis (present vs. absent) and degree of facial dysfunction as between subjects' factors. Emotion detection accuracy declined when visual information declined, an effect that was stronger for anger than for happy expressions. Overall, emotion detection accuracy for happy and angry faces did not differ between VS patients with or without a facial paresis, although exploratory analyses suggest that the ability to recognize emotions in angry facial expressions was slightly more impaired in patients with facial paresis. The findings are discussed in the context of the effects of facial paresis on emotion detection, and the role of facial mimicry, in particular, as an important mechanism for facial emotion processing and understanding.

Show moreThe very early perceptional processes that underlie social categorization can be detected with event-related brain potentials (ERPs). Using this methodology, the present work aims to detect differential attentional processing of ingroup and outgroup members based on gender categories. Specifically, three EEG studies tested how factors that enhance social identity relevance, namely gender identification and contextual salience of gender representation, moderate neural gender categorization effects. Study 1 showed that both women (Study 1a) and men (Study 1b) were more likely to show preferential attention to ingroup over outgroup members, but only when they identified strongly with their gender group. Study 2 showed that when gender categories in an intergroup leadership context were made salient (i.e., when women were numerically underrepresented versus equally represented compared to men), women, irrespective of their level of gender identification, showed preferential attention to ingroup over outgroup members. Together, this work provides empirical evidence for (1) the neural gender categorization effect among both men and women as soon as 100 ms after face perception and (2) the moderating role of factors that enhance social identity relevance in early gender categorization.

Show moreParenting interventions have proven to be effective in enhancing positive parenting behavior and child outcomes. However, the neurocognitive mechanisms explaining the efficacy remain largely unknown. We tested effects of the Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline (VIPP-SD) on mothers' neural processing of child faces. Our primary focus was on the N170 and the secondary focus on the LPP. We expected the intervention to enhance the amplitudes of both ERP components in response to emotional compared to neutral faces. A total of 66 mothers visited the lab for two identical sessions separated by 4.28 months (SD = 0.86) during which a random 33% of the mothers received the VIPP-SD. During both pre- and post-intervention sessions, mothers' electroencephalographic (EEG) activity in response to photographs of children's neutral, happy and angry facial expressions were acquired. In contrast to our expectations, we found smaller (less negative) N170 amplitudes at post-test in the intervention group. There was no intervention effect on the LPP, although overall LPP amplitudes were more positive for neutral and angry compared to happy faces. Our study shows that the N170 is affected by the VIPP-SD, suggesting that the intervention promotes efficient, less effortful face processing.

Show moreThe current study investigated whether changes in the neural processing of faces of infants with a facial abnormality – a cleft lip – mediate effects of the cleft lip on judgments of infant cuteness and approachability. Event-related potentials (ERPs) in response to pictures of faces of healthy infants and infants with a cleft lip, and ratings of cuteness and approachability of these infant faces, were obtained from 30 females. Infants with a cleft lip were rated as less attractive (less cute and approachable) than healthy infants, and both the N170 and P2 components of the ERP were of reduced amplitude in response to pictures of infants with a cleft lip. Importantly, decreased configural processing of infant faces with a cleft lip, as evidenced by reduced N170 amplitudes, mediated the reduced attractiveness ratings for infants with a cleft lip compared to healthy infants. Our findings help elucidate the mechanisms behind the less favorable responses to infants with a cleft lip, highlighting the role of face-specific rather than domain-general neural processes.

Show moreProcesses like gender socialization (the ways in which parents convey information to their children about how girls and boys should behave) often happen unconsciously and might therefore be studied best with neuroscientific measures. We examined whether neural processing of gender-stereotype-congruent and incongruent information is more robustly related to mothers' gendered socialization of their child than mothers' implicit and explicit gender stereotypes. To this end, we examined event-related potentials (ERPs) of mothers (N = 35) completing an implicit gender-stereotype task and mothers' gender stereotypes in relation to observed gendered communication with their child (2-6 years old) in a naturalistic picture-book-reading setting. Increased N2 activity (previously related to attentional processes) to gender stimuli in the implicit gender-stereotype task was associated with mothers' positive evaluation of similar gendered behaviors and activities in the picture book they read with their child. Increased P300 activity (previously related to attention to unexpected events) to incongruent trials in the gender-stereotype task was associated with a more positive evaluation of congruent versus incongruent pictures. Compared to mothers' gender stereotypes, neural processing of gendered information was more robustly related to how mothers talk to their children about boys' and girls' stereotype-congruent and incongruent behavior, and masculine and feminine activities.

Show moreSocial cognitive skills are indispensable for successful communication with others. Substantial research has determined deficits in these abilities in patients with mental disorders. In neurobiological development and continuing into adulthood, cross-cultural differences in social cognition have been demonstrated. Moreover, symptomatic patterns in mental disorders may vary according to the cultural background of an individual. Cross-cultural studies can thus help in understanding underlying (biological) mechanisms and factors that influence behavior in health and disease. In addition, studies that apply novel paradigms assessing the impact of culture on cognition may benefit and advance neuroscience research. In this review, the authors give an overview of cross-cultural research in the field of social cognition in health and in mental disorders and provide an outlook on future research directions, taking a neuroscience perspective.

Show moreSocial acceptance is of key importance for healthy functioning. We used functional magnetic resonance imaging (fMRI) to examine age-related changes in the neural correlates of social acceptance and rejection processing. Participants from four age groups participated in the study: pre-pubertal children (8-10 years), early adolescents (12-14 years), older adolescents (16-17 years) and young adults (19-25 years). During the experiment, participants were presented with unfamiliar faces of peers and were asked to predict whether they expected to be liked or disliked by the other person, followed by feedback indicating acceptance or rejection. Results showed that activation in the ventral mPFC and striatum to social feedback was context-dependent; there was increased activation when participants had positive expectations about social evaluation, and increased activation following social acceptance feedback. Age-related comparisons revealed a linear increase in activity with age in these brain regions for positive expectations of social evaluation. Similarly, a linear increase with age was found for activation in the striatum, ventral mPFC, OFC, and lateral PFC for rejection feedback. No age-related differences in neural activation were shown for social acceptance feedback. Together, these results provide important insights in the developmental trajectories of brain regions implicated in social and affective behavior. Show less
