Paths from core belief disruption to post-traumatic stress symptoms and post-traumatic growth among Korean undergraduates: The mediating role of rumination

The post-traumatic growth (PTG) model proposes that cognitive processing is a key mechanism that leads to growth in the aftermath of traumatic events. Building upon the PTG model, the present study examined the paths from the disruption of core beliefs to post-traumatic stress symptoms (PTSS) and PTG via intrusive and deliberate rumination. The sample includes 370 Korean undergraduate students who reported at least one highly stressful experience in their lifetime. Structural equation modeling demonstrated that disruption of core beliefs predicted PTG both directly and indirectly through multiple pathways: via deliberate rumination, intrusive rumination, and the path from intrusive to deliberate rumination. The disruption of core beliefs positively predicted PTSS only through intrusive rumination. No bivariate relationship was found between PTSS and PTG. These findings support the different roles of intrusive rumination and deliberate rumination in mediating the paths from disruption of core beliefs to PTSS and PTG. Implications and limitations of this study were discussed.     

Epistemic injustice in mathematics

We investigate how epistemic injustice can manifest itself in mathematical practices. We do this as both a social epistemological and virtue-theoretic investigation of mathematical practices. We delineate the concept both positively—we show that a certain type of folk theorem can be a source of epistemic injustice in mathematics—and negatively by exploring cases where the obstacles to participation in a mathematical practice do not amount to epistemic injustice. Having explored what epistemic injustice in mathematics can amount to, we use the concept to highlight a potential danger of intellectual enculturation.

Age,gender, race,socioeconomic status,and birth cohort differences on the children's depression inventory: a meta-analysis

A within-scale meta-analysis was performed on 310 samples of children (ages 8-16; N = 61,424) responding to the Children's Depression Inventory (CDI). Girls' depression scores stayed steady from ages 8 to 11 and then increased between ages 12 and 16. Boys' CDI scores were stable from ages 8 to 16 except for a high CDI score at age 12. Girls' scores were slightly lower than boys' during childhood, but girls scored higher beginning at age 13. There were no socioeconomic status effects and no differences between White and Black samples. However, Hispanic samples scored significantly higher on the CDI. Analyses for birth cohort showed a slight decrease in boys' CDI scores over time and no change for girls. Longitudinal studies demonstrated a marked testing effect.     

The Infrequency-Posttraumatic Stress Disorder scale (Fptsd) for the MMPI-2: development and initial validation with veterans presenting with combat-related PTSD

Researchers have identified difficulties associated with the use of traditional Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) validity scales with survivors of traumatic events. A new scale, the Infrequency-Posttraumatic Stress Disorder scale (Fptsd), was created from MMPI-2 items that were infrequently endorsed by 940 male combat veterans presenting for treatment at the posttraumatic stress disorder (PTSD) clinics of 2 Veterans Affairs Medical Centers. A variety of statistical methods were implemented that preliminarily established Fptsd's validity with a validation sample of 323 additional PTSD-diagnosed combat veterans. Results indicate that, relative to previously established validity and overreporting scales (F, Fb, and Fp), Fptsd was significantly less related to psychopathology and distress and better at discriminating simulated from genuinely reported PTSD. Clinical implications are discussed concerning the use of Fptsd to assess disability-seeking veterans suspected of overreporting PTSD symptoms.     

Gender is a dimension of face recognition

In an experiment, the authors investigated the impact of gender categorization on face recognition. Participants were familiarized with composite androgynous faces labeled with either a woman's first name (Mary) or a man's first name (John). The results indicated that participants more quickly eliminated faces of the opposite gender than faces of the same gender than the face they were looking for. This gender effect did not result from greater similarity between faces of the same gender. Rather, early gender categorization of a face during face recognition appears to speed up the comparison process between the perceptual input and the facial representation. Implications for face recognition models are discussed.     

Cultural Identity and Groups of Belonging

Research into the cultural foundations of psychic structure must take place simultaneously at the individual, group, and psychosocial level of analysis. Identity, as both an individual and a collective phenomenon, and the primacy of the group dimension become manifest in the imaginary space created by groups, in Bion's protomental system. Cultural incorporates function like somatic processes and establish the synchrony of all cultural interactions. Individuation would thus emerge from the shared common base, which in turn is related to the individual's internalization of his group of belonging. A distinction is drawn between primary groups of belonging, which are extensions of family structure and supply the group's cultural identity, and secondary belonging groups, which are instituted by the society. The relationship between transcultural experiences, aiming at achieving unity, and intercultural experiences, which recognize limits and differences, is a source of tension for the individual and the group. Examples are given of the function of excitation screens within instituted groups and of the cultural dimension of the analytic setting.     

Menarche,Menstruation, and Gender Identity: Retrospective Accounts from Women Who Have Undergone Premenopausal Hysterectomy

Hysterectomy (the surgical removal of the uterus) precipitates the end of menstrual cycles in premenopausal women. In this article I explore whether that premature termination of menstrual function negatively affects women's subjective gender identities. Using the grounded theory research approach, I conducted in-depth interviews with 40 diverse respondents who had undergone premenopausal hysterectomy. These women generally acknowledged that, since the time of menarche, they had closely associated menstruation with their gender identities. However, despite some regrets, respondents' primary reaction was almost unanimous relief that they had ceased menstruating. This finding must be viewed in the context of overwhelming and uncontrollable menstrual pain and bleeding that many respondents had previously experienced. Contrary to expressing remorse that they no longer identified with normal women, who menstruate, most respondents sought to disassociate themselves from the normalized suffering that they perceived is endured by all menstruating women.     

Immediate serial recall of words and nonwords: Tests of the retrieval-based hypothesis

In two experiments, the immediate serial recall of lists of words or nonwords was investigated under quiet and articulatory suppression conditions. The results showed better item recall for words but better order recall for nonwords, as measured with proportion of order errors per item recalled. Articulatory suppression hindered the recall of item information for both types of lists and of order information for words. These results are interpreted in light of a retrieval account in which degraded phonological traces must undergo a reconstruction process calling on long-term knowledge of the tobe-remembered items. The minimal long-term representations for nonwords are thought to be responsible for their lower item recall and their better order recall. Under suppression, phonological representations are thought to be minimal, producing trace interpretation problems responsible for the greater number of item and order errors, relative to quiet conditions. The very low performance for nonwords under suppression is attributed to the combination of degraded phonological information and minimal long-term knowledge.
