Patrolling the boundaries of social domains: Neural activations to violations of expectations for romantic and work relationships

The Role of Subgenual Resting-State Connectivity Networks in Predicting Prognosis in Major Depressive Disorder

Background

A seminal study found higher subgenual frontal cortex resting-state connectivity with 2 left ventral frontal regions and the dorsal midbrain to predict better response to psychotherapy versus medication in individuals with treatment-naïve major depressive disorder (MDD). Here, we examined whether these subgenual networks also play a role in the pathophysiology of clinical outcomes in MDD with early treatment resistance in primary care.

Methods

Forty-five people with current MDD who had not responded to ≥2 serotonergic antidepressants (n = 43, meeting predefined functional magnetic resonance imaging minimum quality thresholds) were enrolled and followed over 4 months of standard care. Functional magnetic resonance imaging resting-state connectivity between the preregistered subgenual frontal cortex seed and 3 previously identified left ventromedial, ventrolateral prefrontal/insula, and dorsal midbrain regions was extracted. The clinical outcome was the percentage change on the self-reported 16-item Quick Inventory of Depressive Symptomatology.

Results

We observed a reversal of our preregistered hypothesis in that higher resting-state connectivity between the subgenual cortex and the a priori ventrolateral prefrontal/insula region predicted favorable rather than unfavorable clinical outcomes (rs39 = -0.43, p = .006). This generalized to the sample including participants with suboptimal functional magnetic resonance imaging quality (rs43 = -0.35, p = .02). In contrast, no effects (rs39 = 0.12, rs39 = -0.01) were found for connectivity with the other 2 preregistered regions or in a whole-brain analysis (voxel-based familywise error-corrected p < .05).

Conclusions

Subgenual connectivity with the ventrolateral prefrontal cortex/insula is relevant for subsequent clinical outcomes in current MDD with early treatment resistance. Its positive association with favorable outcomes could be explained primarily by psychosocial rather than the expected pharmacological changes during the follow-up period.

The social domains organization of mentalizing processes in adolescents: a contribution to the conceptualization of personality function and dysfunction in young people

BACKGROUND

We propose and evaluate a contribution to the conceptualization and assessment of personality functioning based on social domains and mentalizing hypotheses. Social domains are distinct social contexts, such as with acquaintances and friends, with differentiated expectations regarding participants' behaviours and social attributions. The capacity to organize social participation according to these expectations requires the ability, we suggest, to modulate mentalizing processes domain by domain. Drawing on evidence that social domain organization is impaired in borderline personality disorder (BPD) and that hypermentalizing, a heightened interpretation of others' motives, thoughts or emotions, is elevated in adolescent BPD, we hypothesized that hypermentalizing levels in adolescents will vary by social domain and that elevated BPD features will be associated with impairment of this domain organization of hypermentalizing.

METHODS

Measures including the borderline personality features scale for children (BPFSC) and the movie for the assessment of social cognition (MASC) were administered to 171 adolescents aged 12-17 recruited from public schools and community organizations in a large metropolitan area in southwestern United States. Mean hypermentalizing scores were computed for adolescent interpretations of sequences in the MASC focusing on the social domains of acquaintance, friends and romantic interactions.

RESULTS

There was a progressive increase in hypermentalizing scores across the acquaintance, friends and romantic interactions (repeated measures ANOVA, p < .001, all pairwise comparisons, p ≤ .02), which was markedly reduced in the presence of elevated BPD features (interaction term, p = .007).

CONCLUSIONS

Hypermentalizing is organized according to social domain and this organization is impaired in the presence of elevated BPD features. The findings are consistent with the proposal that personality functioning entails a social domains organization of hypermentalizing, which is impaired in personality dysfunction. Identifying mentalizing processes domain by domain has the potential to create a personalized focus for the treatment of adolescents with personality difficulties.

Neural Correlates of Antisocial Behavior: The Victim’s Perspective

Antisocial behavior involves actions that disregard the basic rights of others and may represent a threat to the social system. The neural processes associated with being subject to antisocial behavior, including social victimization, are still unknown. In this study, we used a social interaction task during functional magnetic resonance imaging to investigate the neural bases of social victimization. Brain activation and functional connectivity (FC) were estimated and correlated with the Big 5 Questionnaire, Temperament Evaluation in Memphis, Pisa and San Diego (TEMPS-M), and a Questionnaire of Daily Frustration scores. During social victimization, the right occipital and temporal cortex showed increased activation. The temporal cortex also had reduced FC with homotopic areas. Compared to the prosocial interaction, social victimization showed hyperactivation of the dorsomedial and lateral prefrontal cortex, putamen, and thalamus and increased FC of the medial-frontal–striatal–thalamic areas with the ventrolateral prefrontal cortex, insula, dorsal cingulate, and postcentral gyrus. Lastly, neuroticism, irritable temperament, and frustration scores were correlated with the magnitude of neural responses to social victimization. Our findings suggest that social victimization engages a set of regions associated with salience, emotional processing, and regulation, and these responses can be modulated by temperamental and personality traits.

“Don’t Get Your Meat Where You Get Your Bread”: Beliefs and Advice about Workplace Romance

This investigation identified contemporary beliefs about workplace romance and compared how those beliefs have changed since 1986. Different kinds of advice about workplace romance, and how that advice was related to extant beliefs, were also evaluated. A nationwide sample (N = 259) of organizational members with a variety of professional experiences responded to an anonymous online survey. Results indicated that there were three fundamental underlying beliefs about workplace romance: workplace romance is valuable, the right to demand privacy about workplace romance, and anti-workplace romance. Different types of advice—encouraging, warning, gender concern, and silence—were related to these existing beliefs. The substantial associations between beliefs and advice provide evidence for an implicit theory of workplace romance. Personal experience with such relationships was strongly related to the belief that workplace romance is valuable and the right to demand privacy about workplace romance. Additionally, personal experience was also associated with providing advice promoting workplace romance and advocating that employees should remain silent about engaging in such relationships. These results are discussed within the theoretical lens of boundary blending between the work sphere and the private sphere of social life.
