Now you feel it, now you don't: frontal brain electrical asymmetry and individual differences in emotion regulation

Recent theoretical accounts of emotion regulation assign an important role in this process to the prefrontal cortex, yet there is little relevant data available to support this hypothesis. The current study assessed the relation between individual differences in asymmetric prefrontal activation and an objective measure of uninstructed emotion regulation. Forty-seven participants 57 to 60 years old viewed emotionally arousing and neutral visual stimuli while eyeblink startle data were collected. Startle probes were also presented after picture presentation to capture the persistence or attenuation of affect following the offset of an emotional stimulus. Subjects with greater relative left-sided anterior activation in scalp-recorded brain electrical signals displayed attenuated startle magnitude after the offset of negative stimuli. This relation between resting frontal activation and recovery following an aversive event supports the idea of a frontally mediated mechanism involved in one form of automatic emotion regulation.     

Facts,values, and policies: a comment on Howard H. Kendler (2002)

In a recent article, Howard H. Kendler (2002) criticized Kenneth B. Clark and the other social scientists who worked in Brown v. Board of Education for polluting their science with value judgments. This article argues that Kendler's critique is misguided because it conflates a policy judgment with a value judgment. In addition, Kendler inconsistently applied his own standard of objectivity when he examined in the social science used in Brown.     

Differences in psychosocial experiences of employed, unemployed, and student samples of young adults

The author conducted this cross-sectional study to assess the extent to which employed, unemployed, and student samples of young adults could be differentiated on the basis of psychosocial experiences. Forty-four employed, 41 unemployed, and 42 student volunteers completed measures of emotional distress, time structure, financial strain, skill use, task variety, social support, and demographic information. After the effects of educational and income differences were statistically controlled, results indicated that unemployed participants reported poorer functioning than employed and student respondents on most measures. In a discriminant function analysis, 66% of the sample was correctly identified from scores on psychosocial measures, with higher classification rates for employed and unemployed participants. The findings provide additional support for contextual models of mental health and suggest that full-time education partially buffers the negative psychological consequences of unemployment when opportunities for employment are absent.     

Ethnocultural resistance to multicultural training: students and faculty

Teaching diversity courses in mental health programs presents a unique set of issues for the faculty. These courses generate various forms of emotional reactions in students that could take the form of anger, silence, avoidance, and passivity. The purpose of this article is to specifically focus on the experience of students of color who find themselves in these courses and the various ways they respond. This learning process is often impeded by resistance because of the personal experiences of all students, but students of color experience a unique set of resistances in each stage of this process, either because of their own experience or because of a lack of experience with racism, racial and biracial identity development, cultural and bicultural identity, or acculturation issues. Resistance in the classroom interferes with the reciprocal communication between instructors and students and interferes with learning and the development of trust between instructors and students of color. Suggestions are made to help faculty to understand these resistances and to develop appropriate responses for working through the process.     

Influence of the teacher-student relationship on childhood conduct problems: a prospective study.

Examined the influence of the quality of the teacher-student relationship on children's subsequent levels of aggression in a sample of 61 second and third-grade children nominated and rated by their teachers as aggressive. The stability of teachers' and children's reports of relationships quality across academic years was in the low to moderate range. Teachers and children showed little agreement in their reports of relationship quality. Teachers' and children's reports of relationship quality in year 1 (Y1) predicted teacher-rated aggression the following year, controlling for Y1 ratings of aggression. Teachers' reports of relationship quality across Y1 and Y2 predicted peer-rated aggression, but not teacher-rated aggression, in Y3, controlling for Y1 aggression. Consistent with a buffering role for teacher-student relationships, a positive teacher-student relationship was of greatest benefit to children whose mothers reported rejecting parenting histories. We discuss implications for school-based prevention programs.     

Military training and personality trait development: does the military make the man, or does the man make the military?

Military experience is an important turning point in a person's life and, consequently, is associated with important life outcomes. Using a large longitudinal sample of German males, we examined whether personality traits played a role during this period. Results indicated that personality traits prospectively predicted the decision to enter the military. People lower in agreeableness, neuroticism, and openness to experience during high school were more likely to enter the military after graduation. In addition, military training was associated with changes in personality. Compared with a control group, military recruits had lower levels of agreeableness after training. These levels persisted 5 years after training, even after participants entered college or the labor market. This study is one of the first to identify life experiences associated with changes in personality traits. Moreover, our results suggest that military experiences may have a long-lasting influence on individual-level characteristics.     

Attending to detail by communal spider-eating spiders

Communal predators may often need to make especially intricate foraging decisions, as a predator's success may depend on the actions of its neighbours. Here,we consider the decisions made by Portia africana, a jumping spider (Salticidae) that preys on other spiders, including Oecobius amboseli (Oecobiidae), a small prey spider that lives under small sheets of silk (nests) on the walls of buildings. P. africana juveniles settle near oecobiid nests and then ambush oecobiids as they leave or enter the nest. Two or more P. africana juveniles sometimes settle at the same nest and, when an oecobiid is captured, the P. africana juveniles may share the meal. We investigated the joining decisions made by na?ve P. africana juveniles. Experiments were based on using lures (dead spiders positioned in lifelike posture) arranged in a series of 17 different scenes defined by the presence/absence of a nest, the lure types present and the configuration of the lures and the nest. Our findings imply that P. africana juveniles make remarkably precise predatory decisions, with the variables that matter including whether a nest is present, the identity of spiders inside and outside a nest and how spiders are positioned relative to each other and the nest.
