A self-determination theory and motivational interviewing intervention to decrease racial/ethnic disparities in physical activity: rationale and design.

Background: Although the mental and physical benefits of physical activity are well-established, there is a racial/ethnic disparity in activity such that minorities are much less likely to engage in physical activity than are White individuals. Research suggests that a lack of motivation may be an important barrier to physical activity for racial/ethnic minorities. Therefore, interventions that increase participants' motivation may be especially useful in promoting physical activity within these groups.

The Politics of Affirmation Theory: When Group-Affirmation Leads to Greater Ingroup Bias.

It has been well established in the literature that affirming the individual self reduces the tendency to exhibit group-favoring biases. The limited research examining group-affirmation and bias, however, is inconclusive. We argue that group-affirmation can exacerbate group-serving biases in certain contexts, and in the current set of studies, we document this phenomenon directly.

Sleep Duration and Waist Circumference in Adults: A Meta-Analysis.

Background: Previous research has demonstrated a relation between insufficient sleep and overall obesity. Waist circumference (WC), a measure of central adiposity, has been demonstrated to improve prediction of health risk. However, recent research on the relation of insufficient sleep duration to WC in adults has yielded inconsistent findings.

Boasts are a boost: achievement prime self-reactivity predicts subsequent academic performance.

The present research tests the hypothesis that self-reactivity following an achievement prime reflects the strength of achievement goals and is a predictor of future goal-relevant performance. In Studies 1-3, undergraduates reported their grade-point averages (GPAs) following either an achievement goal prime or a control prime. Academic exaggeration (higher self-reported than official GPA) was the indicator of self-reactivity to the prime.

Disentangling child and family influences on maternal expressed emotion toward children with attention-deficit/hyperactivity disorder.

Objective: We used multi-level modelling of sibling-pair data to disentangle the influence of proband-specific and more general family influences on maternal expressed emotion (MEE) toward children and adolescents with attention-deficit/hyperactivity disorder (ADHD).

Method: MEE was measured using the Five Minute Speech Sample (FMSS) for 60 sibling pairs (aged 5 through 17 years) each comprising one proband with ADHD and one child without ADHD. Questionnaire measures were used to assess child and adolescent conduct and emotional problems and maternal depression and ADHD.

Red, rank, and romance in women viewing men.

In many nonhuman species of vertebrates, females are attracted to red on male conspecifics. Red is also a signal of male status in many nonhuman vertebrate species, and females show a mating preference for high-status males. These red-attraction and red-status links have been found even when red is displayed on males artificially.

Individual differences in self-enhancement and self-protection strategies: an integrative analysis.

Research has identified a large number of strategies that people use to self-enhance or self-protect. We aimed for an empirical integration of these strategies. Two studies used self-report items to assess all commonly recognized self-enhancement or self-protection strategies.

Beyond oversights, lies, and pies in the sky: exaggeration as goal projection.

The adaptiveness of overly positive self-evaluation is heavily debated. The present research emphasizes that costs and benefits of positive biases are contingent upon their underlying motives. Five studies explored psychological and performance correlates of the tendency to exaggerate academic performance.

Big tales and cool heads: academic exaggeration is related to cardiac vagal reactivity.

Students who exaggerate their current grade point averages (GPAs) report positive emotional and motivational orientations toward academics (Gramzow & Willard, 2006; Willard & Gramzow, 2007). It is conceivable, however, that these self-reports mask underlying anxieties. The current study examined cardiovascular reactivity during an academic interview in order to determine whether exaggerators respond with a pattern suggestive of anxiety or, alternatively, equanimity.

Exaggerating current and past performance: motivated self-enhancement versus reconstructive memory.

The authors propose distinct reasons why individuals exaggerate their current and past performance. Current performance is of motivational and self-evaluative significance, and exaggerations of current performance often stem from motivated self-enhancement concerns. Self-reports of past performance are influenced less by motivated self-enhancement, instead reflecting more subtle biases in reconstructive memory.

Self-esteem and favoritism toward novel in-groups: the self as an evaluative base.

The self-as-evaluative base (SEB) hypothesis proposes that self-evaluation extends automatically via an amotivated consistency process to affect evaluation of novel in-groups. Four minimal group studies support SEB. Personal trait self-esteem (PSE) predicted increased favoritism toward a novel in-group that, objectively, was equivalent to the out-group (Study 1).

Perceiving personal discrimination: the role of group status and legitimizing ideology.

It was hypothesized that relative group status and endorsement of ideologies that legitimize group status differences moderate attributions to discrimination in intergroup encounters. According to the status-legitimacy hypothesis, the more members of low-status groups endorse the ideology of individual mobility, the less likely they are to attribute negative outcomes from higher status group members to discrimination. In contrast, the more members of high-status groups endorse individual mobility, the more likely they are to attribute negative outcomes from lower status group members to discrimination.
