Expanding understanding of adolescent neural sensitivity to peers: Using social information processing theory to generate new lines of research

Adolescence is a period of normative heightened sensitivity to peer influence. Individual differences in susceptibility to peers is related to individual differences in neural sensitivity, particularly in brain regions that support an increasingly greater orientation toward peers. Despite these empirically-established patterns, the more specific psychosocial and socio-cognitive factors associated with individual differences in neural sensitivity to peer influence are just beginning to gain research attention. Specific features of the factors that contribute to how adolescents process social information can inform understanding of the psychological and neurobiological processes involved in what renders adolescents to be more or less susceptible to peer influences. In this paper, we (1) review the literature about peer, family, and broader contextual influences on sensitivity to peers' positive and negative behaviors, (2) outline components of social information processing theories, and (3) discuss features of these models from the perspectives and social cognitive development and social neuroscience. We identify gaps in the current literature that need to be addressed in order to gain a more comprehensive view of adolescent neural sensitivity to peer influence. We conclude by suggesting how future neuroimaging studies can adopt components of this social information processing model to generate new lines of research.

Towards the understanding of the core of general personality disorder factor: g-PD and its relation to hostile attributions

There is a general consensus that personality disorders (PDs) share a general factor (g-PD) overlapping with the general factor of psychopathology (p-factor). The general psychopathology factor is related to many social dysfunctions, but its nature still remains to some extent ambiguous. We posit that hostile attributions may be explanatory for the factor common for all PDs, i.e., interpersonal problems and difficulty in building long-lasting and satisfying relationships of all kinds. Thus, the main objective of the current project was to expand the existing knowledge about underlying factors of g-PD with regard to hostile attributions. We performed a cross-sectional study on a representative, community sample of Poles (N = 1031). Our hypotheses were primarily confirmed as hostile attributions predicted p-factor. However, the relation was positive only for hostile attributions related to ambiguous situations involving relational harm and physical harm done by female authorities and negative in case of hostile attributions in situations involving physical harm done by peers. Additionally, paranoia-like thoughts strongly related to hostile attributions and independently predicted g-PD. The results contribute to the current discussion on the nature of the g-PD, confirm that hostile attributions and paranoia are a crucial aspect of personality pathology, and indicate the importance of working on these cognitions in the course of therapeutic work.

Reduced attention toward faces, intentionality and blame ascription in violent offenders and community-based adults: Evidence from an eye-tracking study

People typically have a strong bias in attention toward faces to help them understand social interactions. Nonetheless some people, like incarcerated offenders and psychopaths, exhibit deficits in "face reading," which may impair their interpretations, especially in case of attribution allocation in harmful events. In these cases, the ascription of intentionality is key in understanding the allocation of blame and structuring social information processing. Consequently, in the current study, in addition to typically studied intentionality and blame ascription levels (subfactors of hostile attributions), we also propose a new indicator of hostile attributions: intentionality/blame isomorphism, indicating reduced differentiation between those two factors. Violent prison inmates (N = 63) and community-based adults without previous history of incarceration (N = 63) took part in an eye-tracking study. In line with our hypotheses, offenders exhibited reduced attention orienting to faces as well as greater intentionality/blame isomorphism. In the case of both groups, people looked longer at the faces of the harm doer compared with the harm receiver. Additionally, greater intentionality/blame isomorphism predicted reduced attention to faces; however, when group status was included in the model, it became the only significant predictor of the attention to faces. Future studies should examine the origins of these gaze and attribution patterns and investigate consequences related to social perception and interactions of people prone to violence.

External locus of control and cognitive ability independently distinguish men in prison from community living non-offending men

BACKGROUND

The ability to cope with failure and subsequent feedback is crucial for prisoner rehabilitation. Impaired executive function in prisoners, high trait aggression and external locus of control can undermine the capacity to react to feedback in socially adaptive ways.

AIM

To investigate the relationships between aggression, locus of control, and attribution in an experimental task involving feedback about failure and success.

METHODS

Two groups were compared: 1. Imprisoned men, 2. Community living men without a history of incarceration. Aggression, locus of control and reasoning ability were assessed by means of psychometric instruments. An experimental task building on cognitive ability and providing performance-related feedback was carried out. Attributions of failure and success were measured using an ad hoc rating scale.

RESULTS

Prisoners reported higher levels of aggression and generalised externality, but poorer reasoning ability than the comparison group. Aggression was associated with external locus of control. In the experimental task, the community group showed higher success rates; higher scores on the task were correlated with less external attribution of own performance. Higher external locus of control and lower reasoning ability were independently associated with being a prisoner in a logistic regression model.

CONCLUSIONS AND IMPLICATIONS

Men in prison were characterised by greater social and fatalistic externality paired with lower reasoning ability than never incarcerated community men. In-prison rehabilitation strategies should pay early attention to improving reasoning ability and enabling men to recognise likely overuse of externally attributing their difficulties to fate, then helping them to become more realistic in their attributions and make use of realistic feedback.

Situational context influences the degree of hostile attributions made by individuals with schizophrenia or autism spectrum disorder

OBJECTIVES

Previous work has demonstrated that the tendency to make hostile attributions is not a stable trait but varies across different social situations. Therefore, we sought to investigate whether hostile attributions within clinical samples are better understood as a persistent characteristic or one that varies across contexts.

METHODS

The current analyses investigated patterns of attributions among people diagnosed with schizophrenia (SCZ, n = 271) or autism spectrum disorder (ASD, n = 100) and non-clinical control participants (NCC, n = 233) in an existing data set.

RESULTS

Results showed that specific relational features in vignettes portraying different social encounters influence the way people make attributions and that variability across contexts is present in both non-clinical and clinical populations. Like non-clinical participants, participants diagnosed with ASD ascribed the greatest hostility to a scene involving an authority figure. In contrast, SCZ participants reported the greatest hostility in response to a scene involving a friend.

CONCLUSIONS

These findings suggest that salient environmental factors should be considered when assessing social cognitive skills and biases.

PRACTITIONER POINTS

Hostile attributions should be perceived as situational constructs rather than stable and persistent characteristics. Hostile attributions were most prevalent among persons diagnosed with schizophrenia; however, on average, all participants showed greater hostility for situations involving an authority figure, an acquaintance, or a friend relative to those involving a co-worker or stranger. Psychotherapists and clinicians working with people diagnosed with schizophrenia or autism spectrum disorder could work on identifying situation triggers, which may prompt hostile attributions. Psycho-educational and psychotherapeutic interventions can be altered based on individual triggers of hostile attributions, and attempts can be made to lessen these attributions. Paranoia appears to be linked to hostile attributions regardless of the specific clinical diagnosis and should be considered in the therapeutic process.
