Cognitive contributions of the ventral parietal cortex: an integrative theoretical account

Although ventral parietal cortex (VPC) activations can be found in a variety of cognitive domains, these activations have been typically attributed to cognitive operations specific to each domain. In this article, we propose a hypothesis that can account for VPC activations across all the cognitive domains reviewed. We first review VPC activations in the domains of perceptual and motor reorienting, episodic memory retrieval, language and number processing, theory of mind, and episodic memory encoding. Then, we consider the localization of VPC activations across domains and conclude that they are largely overlapping with some differences around the edges. Finally, we assess how well four different hypotheses of VPC function can explain findings in various domains and conclude that a bottom-up attention hypothesis provides the most complete and parsimonious account.     

Stability and Change of Social Goals in Adolescence

This study provides a comprehensive analysis of continuity and change in social goals using the interpersonal circumplex (IPC) model across adolescence (ages 11–16). Five complementary definitions of stability were examined: structural, rank‐order, absolute, individual, and ipsative. Data were taken from a longitudinal study of early adolescent problem behavior. Social goals were assessed during each wave, with data collection occurring at three annual intervals (Wave 1, ages 10–12). A community sample of adolescents (N = 387) was recruited. Adolescents were evenly split on gender, and a majority (82.7%) was White. Results suggest a modest increase in stability across social goals, yet significant interindividual heterogeneity. Although levels of Agentic and Communal factors increase over time, these patterns were driven by decreases in the Submissive and Separate octants. This offers evidence for the utility of examining lower‐order facets of interpersonal dispositions, as it provides a nuanced picture of adolescent personality development. Furthermore, findings suggest that change and continuity in social goals may both be relevant in this developmental period. The difficulty is accounting for trait stability as well as change, and the IPC model may be particularly useful for meeting this challenge.     

Psychological Distress and Associated Factors Among a Sample of Pregnant Women in South Africa

We sought to identify the prevalence of psychological distress and associated factors among pregnant women who were patients at antenatal primary care clinics in a South Africa district. A cross-sectional study using systematic sampling was conducted among 1497 pregnant women (age range=18 to 47 years; mean age=26.6 years, SD=6.1; Black African=98%), with a mean gestational age of 6.5 months (SD=1.6). They completed the Kessler Psychological Distress Scale, a measure of psychological distress. Results showed high rates of severe psychological distress (26.5%). Increased distress was in multivariate analysis associated with having had an STI (other than HIV), being unhappy about current pregnancy, and HIV positive. Identification of pregnant women with psychological distress in public health clinics is crucial for effective and appropriate targeted interventions.     

Being a Body: Women’s Appearance Related Self-Views and their Dehumanization of Sexually Objectified Female Targets

When sexually objectified, women are reduced to their bodies or sexual body parts and become likely targets of dehumanization. Not only men, but also women engage in this process. In the present research, we tested the link between women’s appearance related self-views and their tendency to dehumanize sexually objectified female targets. Specifically, we test two mediational models and predict that (1) women’s motivation to look attractive to men and (2) their tendency to internalize the sociocultural beauty standards are linked with the dehumanization of sexually objectified female targets, and their level of self-objectification mediates both relations. To test these hypotheses, a sample of 55 heterosexual undergraduate female students from Northern Italy volunteered. Participants’ motivation to look attractive to men, their level of internalization of the sociocultural beauty standards, and their tendency to self-objectify was measured. Results confirmed that only sexually objectified female targets were significantly dehumanized, while their non-objectified counterparts were not. Moreover, both participants’ motivation to look attractive to men and their tendency to internalize the sociocultural beauty standards were positively linked with the dehumanization of sexually objectified female targets. As expected, these relations were mediated by participants’ level of self-objectification. These results show that higher levels of self-objectification among those women who are motivated either to look attractive to men or to internalize the sociocultural beauty standards are linked with their tendency to dehumanize sexually objectified female targets.     

Some Remarks on For-me-ness and Empathy

Abstract

My discussion of Self and Other takes issue with two distinct theses defended by Zahavi. The first concerns Zahavi's argument for the first-personal character of experience and its related thought experiment. My second remark is about Zahavi’s restriction of empathy to direct perception.     

Avoidant coping in panic disorder: a yohimbine biological challenge study

Abstract

Few studies have addressed whether the use of avoidance-oriented coping strategies is related to the development of panic in patients with panic disorder(PD). Self-report, clinician-rated, and physiological data were collected from 42 individuals who participated in a yohimbine biological challenge study, performed under double-blind, placebo-controlled conditions. Participants included 20 healthy controls and 22 currently symptomatic patients who met DSM-IV-TR diagnostic criteria for PD. Consistent with prediction, patients with PD who had higher perceived efficacy of avoidance-oriented strategies in reducing anxiety-related thoughts reported increased severity in panic symptoms during the yohimbine challenge condition as compared to the placebo. Further, patients with PD who had more fear of cognitive dyscontrol, cardiovascular symptoms, and publicly observable anxiety also reported increased severity in panic symptoms during the challenge. Healthy controls who had more fear of cardiovascular symptoms similarly reported increased severity in panic symptoms during the challenge. No effects were found for heart rate response to the challenge agent. These results provide support for the role of avoidance-oriented coping strategies and fear of anxiety-related symptoms as risk and maintenance factors in the development of panic symptoms, particularly within a biological challenge model.
