Oxytocin increases willingness to socially share one's emotions

Oxytocin (OT) is a neuropeptide that is attracting growing attention from researchers interested in human emotional and social behavior. There is indeed increasing evidence that OT has a calming effect and that it facilitates pair‐bonding and social interactions. Some of OT's effects are thought to be direct, but it has been suggested that OT also may have indirect effects, mediated by changes in behavior. One potentially relevant behavioral change is an increased propensity for “emotional sharing” as this behavior, like OT, is known to have both calming and bonding effects. In this study, 60 healthy young adult men were randomly assigned to receive either intranasal placebo (PL; n = 30) or oxytocin (OT; n = 30). Participants were then instructed to retrieve a painful memory. Subsequently, OT and placebo participants’ willingness to disclose to another person event‐related facts (factual sharing) vs. event‐related emotions (emotional sharing) was evaluated. Whereas the two groups were equally willing to disclose event‐related facts, oxytocin was found to specifically increase the willingness to share event‐related emotions. This study provides the first evidence that OT increases people's willingness to share their emotions. Importantly, OT did not make people more talkative (word counts were comparable across the two groups) but instead increased the willingness to share the specific component that is responsible for the calming and bonding effects of social sharing: emotions. Findings suggest that OT may shape the form of social sharing so as to maximize its benefits. This might help explain the calming and bonding effects of OT.     

Cultural influences on terror management: Independent and interdependent self-esteem as anxiety buffers

Terror management theory (TMT) proposes that self-esteem serves as a defense against the fear of death. Previous research has suggested that independent self-esteem is more salient in individualist cultures, whereas interdependent self-esteem is more salient in collectivist cultures. Thus, we hypothesized that in collectivist cultures, independent self-esteem would play a lesser role and interdependent self-esteem a greater role in terror management, compared to individualist cultures. The results support this prediction. In Study 1, personal self-esteem was negatively associated with death anxiety in samples from a Western (Austria) and Eastern (China) culture. However, both self-liking and self-competence were negatively associated with death anxiety among Austrian participants, but only self-liking (and not self-competence) was so among Chinese participants. Surprisingly, collective self-esteem was not significantly correlated with death anxiety. Yet, Study 2 showed that among Chinese participants, relational self-esteem was negatively associated with death anxiety. Study 3 examined the roles of relational versus personal self-esteem in moderating the effects of mortality salience on worldview defense. Among Chinese participants, relational rather than personal self-esteem increased the defense of worldviews centered on collectivist-Chinese values following mortality salience (Study 3a). In contrast, among Austrian participants, personal rather than relational self-esteem attenuated the effect of mortality salience on the defense of individualist-Austrian worldviews (Study 3b). Self-esteem serves a terror management function in both collectivist and individualist cultures; however, the differences between cultural worldviews determine the type of self-esteem that is more relevant to terror management processes.     

Construct Validity of the Social Physique Anxiety Scale in a French Adolescent Sample

The present study explored the validity of constriction as an indicator of depression. Twenty-five patients displaying constriction in their Bender records and 25 patients not showing this indicator were compared with regard to MMPI Depression scores. A significant difference was found between D scores of these two groups (p<.05), supporting the validity of the indicator as an index of depression. Constriction was found to be infrequent, occurring in only 5.5% of the patient records. Although the indicator seems to be of some value as an indicator of depression its utility is lessened due its low rate of occurrence.     

Self-Induced Water Intoxication in a Psychiatric Asylum: A Case Study of Diagnostic Categorization and Regulation

In this article, we examine the regulation of psychiatric patients becoming intoxicated from drinking excessive amounts of liquids at a large psychiatric asylum in Canada. We analyze how medical staff created a formalized diagnostic category and a specialized ward for its treatment. We consider the institutional context in which “water intoxication” was developed as a diagnostic category and we examine the impact of this diagnosis on the regulation of asylum patients. Finally, we discuss the patients’ opposition to treatment as well as the impact of “water intoxication” on their self-identity and institutional status.     

Investigating Physiological and Self-Reported Mediators of Stereotype Lift Effects on a Motor Task

Achievement gaps between social groups may result from stereotype threat effects but also from stereotype lift effects—the performance boost caused by the awareness that an outgroup is negatively stereotyped. We examined stereotype lift and threat effects in the motor domain and investigated their mediation by task involvement and self-confidence, measured by heart rate reactivity and self-reported indices. Males and females performed a balance task about which negative stereotypes about either males or females were given. No gender information was given in a control condition. Results showed no stereotype threat but a stereotype lift effect, participants performing significantly better after negative outgroup stereotypes were explicitly linked to performance on the balance task compared to the control condition. Concerning males, this effect was mediated by higher self-confidence and task involvement. The implications of these results for understanding the gender inequalities in the motor domain are discussed.     

Responsividad y condicionamiento semántico en relación con el ciclo menstrual

Resumen

El trabajo examina el efecto de cambios internos atribuibles al ciclo menstrual en la responsividad y condicionamiento psicofisiológico de un grupo de mujeres normales con ciclos naturales. Los sujetos fueron examinados Premenstrualmente (PM) o Intermenstrualmente (IM), utilizando como variables dependientes medidas psicofisiológicas (Conductancia de la Piel y Tasa Cardíaca) y cuestionarios. Los sujetos IM mostraron mayor responsividad y habituación en la actividad cardíaca y menores latencies de recuperación en la conductancia de la piel ante estimulación auditiva intensa, así como mayor condicionamiento en la conductancia de la piel (respuestas al segundo intervalo) que los sujetos PM. Las medidas actuales y retrospectivas de estados emocionales mostraron mayor afecto negativo (fatiga y tensión) en los sujetos PM y en l a fase premenstrual. Estos resultados son comparados con los de estudios similares realizados con pacientes fóbicas y son discutidos en términos de diferentes estados emocionales y de activación fisiológica asociados a las fases menstruales examinadas.     

La falacia de la validación personal: Más efectos placebo

RESUMEN

En este artículo se pone a prueba la influencia de efectos placebo en la aceptación de informes evaluativos y diagnósticos por los sujetos. Tras introducir brevemente el tema y plantear las hipótesis, los autores describen el método y los resultados de su investigación. En la discusión explican que estos resultados sugieren que la aceptación del diagnóstico que ofrece un profesional es un fenómeno general independiente de las características personales de los individuos que lo reciben, poniendo en entredicho el fenómeno de la validación personal y, al mismo tiempo, interactúa con determinadas características profesionales de los sujetos, ligadas a imágenes de personalidad a las que son más propensos. Los autores también analizan una limitación importante de su trabajo, el tamaño reducido de la muestra, y finalizan destacando que es el contenido del informe, más que el tipo de pruebas o profesionales, lo que parece afectar diferencialmente a distintos grupos profesionales.     

The Eating Attitudes Test-26 Revisited using Exploratory Structural Equation Modeling

Most previous studies have failed to replicate the original factor structure of the 26-item version of the Eating Attitudes Test (EAT-26) among community samples of adolescents. The main objective of the present series of four studies (n?=?2178) was to revisit the factor structure of this instrument among mixed gender community samples of adolescents using both exploratory structural equation modeling (ESEM) and confirmatory factor analysis (CFA). First, results from the ESEM analyses provided satisfactory goodness-of-fit statistics and reliability coefficients for a six-factor model of the EAT with 18 items (EAT-18) closely corresponding to the original seven-factor structure proposed for the 40-item version of the EAT. Second, these analyses were satisfactorily replicated among a new sample of community adolescents using CFA. The results confirmed the factor loading and intercept invariance of this model across gender and age groups (i.e., early and late adolescence), as well as the complete invariance of the EAT-18 measurement model between ethnicities (i.e., European versus African origins) and across weight categories (i.e., underweight, normal weight and overweight). Finally, the last study provided support for convergent validity of the EAT-18 with the Eating Disorder Inventory and with instruments measuring global self-esteem, physical appearance, social physique anxiety and fear of negative appearance evaluation.
