Postextinction infusion of a mitogen-activated protein kinase inhibitor into the medial prefrontal cortex impairs memory of the extinction of conditioned fear

We investigated whether postextinction training infusion of PD098059, a selective inhibitor of mitogen-activated protein kinase (MAPK) activation, into the medial prefrontal cortex, would impair retention of extinction learning in rats. We found that immediate, but not late (2 or 4 h), postextinction infusion of PD098059 provoked a full return of conditioned freezing. These results suggest that activation of prefrontal MAPK in early stages of postextinction training participates in processes that protect against spontaneous recovery of aversive responses.     

In the privacy of their own homes: using the internet to assess racial bias

Recent studies suggest that research participants show reduced distortion of their taboo attitudes and behaviors when they take part in Internet-based procedures from outside the laboratory. We explored whether such procedures would reduce distortion in the assessment of racial bias. In Study 1, White participants who completed the study in the laboratory evaluated Black targets more favorably than White targets. This unexpected "outgroup-favoring" pattern occurred in both pencil-and-paper and Internet versions of the study, showing that modality did not produce it; but when participants worked outside the laboratory via the Internet, this pattern disappeared. Study 2 replicated the above findings and further indicated that the reduced distortion in Internet-based studies was due to the removal of the experimenter rather than removing the participants from the laboratory environment. The implications of these findings for the study of controlled processes of prejudice and the nature of Internet-based social communication are discussed.     

Who's Being Served? "Self-Serving" Attributions in Social Hierarchies

Making external attributions for negative events, though often considered “self-serving,” also implies that the attributor is not in control of critical resources. We hypothesized that making external attributions for negative events will lead to impressions of powerlessness. Because individuals in high-status roles are expected to have power and control, external attributions may violate these role expectations; thus, we further hypothesized that status would moderate the relationship between attributions and interpersonal outcomes. Specifically, more negative impressions and affect will be directed toward high-status individuals who make external attributions than toward their lower status counterparts. Three studies were conducted, one using a role-play methodology, one using an experimentally created hierarchy, and one using vignettes. The results supported our hypotheses: external attributions can be highly disserving for people in high-status positions.     

Women of the “Sandwich” Generation and Multiple Roles: The Case of Russian Immigrants of the 1990s in Israel

It has been suggested that adding elder care tothe list of women's multiple roles may significantlyjeopardize their well-being and mental health. Thisstudy explored the experiences with multiple roles among Jewish women who immigrated to Israelfrom the former Soviet Union in the early 1990s withtheir extended families. The thirty informants for thestudy (aged between 35 and 55) represented a variety of pre-emigration backgrounds. Their commondenominator was in multiple roles (employment andcaregiving to both children and ageing parents) coupledwith the challenges of resettlement in a country swept by the mass influx of immigrants. Facingdownward social mobility, marital distress, and problemswith adolescent children, the women of thissandwich generation also had to supporttheir uprooted parents. The growing dependency and declininghealth of the elders significantly burdened the womenand hindered their occupational upgrading and socialintegration in Israel. Exhaustion and tight time budgets led to somatization and poor self-careamong middle-aged women. Social services' role in eldercare was minimal. The informants' social networks weremainly co-ethnic, and their coping tools drew on Israeli-Russian subculture. The studyconcludes that, even in the relatively egalitarianRussian-Soviet gender system, women function asprincipal caregivers, often at the expense of other lifegoals.     

A Lay Perspective on the Accuracy of Eyewitness Testimony1

To understand more about what laypeople think they “know” about eyewitness testimony, 276 jury-eligible university students were asked to indicate what factors they believe affect the accuracy of eyewitness testimony. In contrast to the large proportion of eyewitness-memory research that concerns system variables, the lay respondents overwhelmingly generated factors related to estimator variables, while system-variable factors such as police questioning and identification procedures were rarely mentioned. Respondents also reported that their own common sense and everyday life experiences were their most important sources of information about the accuracy of eyewitness testimony. Not only do these results clarify the need for further research on the lay perspective of eyewitness testimony, but they also provide some insight into the way in which many jurors might approach cases involving eyewitness evidence.     

Attachment Style Differences and Depression in African American and European American College Women: Normative Adaptations?

This study examined ethnic differences in attachment styles and depression among African American and European American college women. African American women reported less favorable views of others, which suggests that attachment styles emphasizing caution in relationships may be normative and adaptive for these women. There were no differences between groups in views of self or reports of depressive symptoms. Implications for long‐term relationships and counseling are discussed. Este estudio examinó las diferencias étnicas en estilos de apego y depresión entre estudiantes universitarias Afroamericanas y Euroamericanas. Las mujeres Afroamericanas expresaron una visión menos favorable sobre los demás, lo que sugiere que los estilos de apego que enfatizan la precaución en las relaciones pueden ser normativos para estas mujeres, y el resultado de su adaptación. No hubo diferencias entre los grupos en cuanto a la visión de sí mismas o expresión de síntomas depresivos. Se discuten las implicaciones para las relaciones a largo plazo y la consejería.     

On Categories and A Posteriori Necessity: A Phenomenological Echo

This article argues for two related theses. First, it defends a general thesis: any kind of necessity, including metaphysical necessity, can only be known a priori. Second, however, it also argues that the sort of a priori involved in modal metaphysical knowledge is not related to imagination or any sort of so‐called epistemic possibility. Imagination is neither a proof of possibility nor a limit to necessity. Rather, modal metaphysical knowledge is built on intuition of philosophical categories and the structures they form.
