Androginia psicológica y flexibilidad comportamental

RESUMEN

Los autores investigan la hipótesis de que los sujetos andróginos son más flexibles en su implicación y bienestar ante tareas que se tipifican culturalmente como pertenecientes al “otro” sexo. Comienzan repasando la literatura psicológica acerca de androginia psicológica y flexibilidad comportamental y seguidamente concretan sus hipótesis: comprobar que los individuos andróginos a) mostrarán una mayor implicación en tareas tanto masculinas como femeninas, b) preferirán en menor medida actividades apropiadas a su sexo y c) experimentarán un mayor bienestar psicológico al desarrollar este tipo de actividades que cualquier otro grupo de rol sexual. Tras describir el método y los resultados del trabajo, los autores ofrecen una discusión final de éstos, en la que destacan que su investigación parece confirmar los resultados de Bem: parece que es el rol sexual andrógino el que siente un mayor grado de bienestar al realizar conductas que son sancionadas socialmente como inapropiadas a su sexo y el que escoge un mayor número de este tipo de comportamientos. Los autores finalizan afirmando que también parece haber quedado respaldada la validez predictiva del Bem Sex Role Inventory.     

Wanting, having, and needing: integrating motive disposition theory and self-determination theory

Four studies explored the motivational and experiential dynamics of psychological needs, applying both self-determination theory and motive disposition theory. In all 4 studies, motive dispositions toward achievement and affiliation ("wanting" particular experiences) predicted corresponding feelings of competence and relatedness ("having" those experiences). Competence and relatedness in turn predicted well-being, again indicating that these 2 experiences may really be "needed." Illuminating how wanting gets to having, in Studies 2 and 3, participants reported greater self-concordance for motive-congruent goals, which, in longitudinal Study 3, predicted greater attainment of those goals and thus enhanced well-being. Study 4 replicated selected earlier results using an implicit as well as an explicit motive disposition measure. Supporting the presumed universality of competence and relatedness needs, in no studies did motive dispositions moderate the effects of corresponding need-satisfaction on well-being. Discussion focuses on a "sequential process" model of psychological needs that views needs as both motives that instigate and outcomes that reward behavior.     

Testing the cognitive catalyst model of depression: does rumination amplify the impact of cognitive diatheses in response to stress?

Recent studies have found that rumination functions as a catalyst of cognitive vulnerability to depression. Specifically, these studies have reported synergistic effects between rumination and negative cognitive content (beliefs and attitudes), such that rumination amplifies the association between negative cognitive content and depression (Ciesla & Roberts, 2002, 2007; Robinson & Alloy, 2003). The current study extended this work by testing whether cognitive vulnerability involving the combination of negative cognitive content and rumination increases the impact of stress on the course of depressive symptoms. One hundred ninety-one college students with elevated depressive symptoms participated in a two-wave longitudinal study. Results indicate that the maintenance of depressive symptoms was predicted by the three-way interaction of negative cognitive content, rumination, and stressful life events. More specifically, students who endorsed both maladaptive cognitive content and a tendency to ruminate were particularly vulnerable to the deleterious impact of life stress.     

Self-construal and social anxiety: Considering personality

Self-construal has been identified as a potential means to explain cultural differences in social anxiety. Yet, research findings suggest that self-construal is an individual difference as much as a cultural difference. We tested for mediation and moderation regarding self-construal, social anxiety, and other primary individual difference constructs. Our results indicated that the relation of extraversion and neuroticism to social anxiety was partially mediated by independent self-construal. In addition, the relationship between social anxiety and interdependent self-construal was moderated by neuroticism. These results suggest that personality traits play an important role in the relationship between social anxiety and self-construal. Clinical interventions that consider the interplay between self-construal and personality may be helpful in decreasing social anxiety.     

A taxometric analysis of actual Internet sports gambling behavior

This article presents findings from the first taxometric study of actual gambling behavior to determine whether we can represent the characteristics of extreme gambling as qualitatively distinct (i.e., taxonic) or as a point along a dimension. We analyzed the bets made during a 24-month study period by the 4,595 most involved gamblers among a cohort of 48,114 people using an Internet service to gamble on sporting events. We applied two taxometric procedures (i.e., MAMBAC and MAXCOV) to three indicators of betting behavior: total money lost, total number of bets, and total money wagered. The results fail to provide support for the view that the most involved Internet sports gamblers include a distinct category of gamblers. More research is necessary to clarify the similar features of recreational and extreme gamblers and the dimensions that scientists can use to measure these behaviors. Finally, we discuss the implications of these findings for clinical, research, and public policy activities.     

Report of the AMA Council on Ethical and Judicial Affairs: professionalism in the use of social media

Although many physicians have been using the internet for both clinical and social purposes for years, recently concerns have been raised regarding blurred boundaries of the profession as a whole. In both the news media and medical literature, physicians have noted there are unanswered questions in these areas, and that professional self-regulation is needed. This report discusses the ethical implications of physicians' nonclinical use of the internet, including the use of social networking sites, blogs, and other means to post content online. It does not address the clinical use of the internet, such as telemedicine, e-prescribing, online clinical consultations, health-related websites, use of electronic media for clinical collaboration, and e-mailing patients (some of which are already covered in the AMA's Code of Medical Ethics).     

False recognition in women with a history of childhood emotional neglect and diagnose of recurrent major depression

While previous research has suggested that adults with a history of childhood sexual abuse may be more prone to produce false memories, little is known about the consequences of childhood neglect on basic memory processes. For this reason, the authors investigated how a group of women with a history of childhood emotional neglect (CEN) and diagnosed with recurrent Major Depressive Disorder (MDD) performed on the Deese–Roediger–McDermott paradigm in comparison to control groups. The results indicated that women with MDD and CEN were actually less prone to produce false memories relative to both women with MDD but no CEN and healthy women without MDD and any form of childhood maltreatment. These findings were explained in terms of the inability to extract/retrieve gist memories that support false recognition of critical lures, an explanation that seems to fit well with emerging MRI findings linking childhood neglect to reduced volume of brain regions associated to memory function.     

Perception of facial expression depends on prior attention

Attending versus ignoring a stimulus can later determine how it will be affectively evaluated. Here, we asked whether attentional states could also modulate subsequent sensitivity to facial expressions of emotion. In a dual-task procedure, participants first rapidly searched for a gender-defined face among two briefly displayed neutral faces. Then a test face with the previously attended or ignored face’s identity was presented, and participants judged whether it was emotionally expressive (happy, angry, or fearful) or neutral. Intensity of expression in the test face was varied so that an expression detection threshold could be determined. When fearful or angry expressions were judged, expression sensitivity was worse for faces bearing the same identity as a previously ignored versus attended face. When happy expressions were judged, sensitivity was unaffected by prior attention. These data support the notion that the motivational value of stimuli may be reduced by processes associated with selective ignoring.     

Self-Objectification and Pregnancy: Are Body Functionality Dimensions Protective?

Objectification theory contends that women are socialized to view their body as an object to be evaluated by others (Fredickson and Roberts 1997). In contrast, pregnancy may be a time that women are more attuned to their body??s functionality. Extending objectification theory, we investigate relationships among body surveillance, awareness and appreciation of body functionality, depressive symptoms, and prenatal health behaviors among an on-line sample of 156 predominantly White, middle-class pregnant women from throughout the U.S recruited through maternity stores, message boards, listservs, and snowballing techniques. We examine whether higher levels of awareness and appreciation of body functionality may attenuate, and thereby possibly protect women from the negative effects of high body surveillance. We found that higher body surveillance was associated with depressive symptoms and, although not significant, tended to be associated with engagement in unhealthy prenatal behaviors. Awareness and appreciation of body functionality were each associated with fewer depressive symptoms and less engagement in unhealthy prenatal behaviors. Supporting our hypotheses, we found that at higher levels of appreciation of body functionality, the relationship between body surveillance and engagement in unhealthy behaviors was attenuated. However, in contrast to our hypotheses, the relationship between body surveillance and depression was stronger at higher levels of awareness of body functionality, and attenuated at lower levels. These findings suggest appreciation of body functionality may buffer negative effects of body surveillance. Future research examining these relationships over the course of pregnancy, and among ethnically and socioeconomically diverse women, is needed.     

Mother-Child and Father-Child Interactional Synchrony in Dyadic and Triadic Interactions

Patterns of interactional synchrony were compared in mother-child and father-child dyads during dyadic and triadic interactions. Forty-two dual-earner families from the French province of Québec, Canada, participated in the study with their 32 months-old child. Parent?Cchild interactions were coded using a taxonomy including the social partners?? physical proximity, visual and body orientation, and dyadic involvement. Analyses show similar patterns of interactional synchrony in mother-child and father-child dyads in the dyadic context while father-child dyads presented less interactional synchrony than mother-child dyads when interacting in triad. Discussion focuses on the impact of the context and on the factors that could explain the changes in father-child patterns of interaction from one context to another.
