Adolescence is thought of as a stress-sensitive developmental period. While many studies have compared adolescent responses to stress relative to that of adults, a growing body of work has examined stress responses in juveniles. Here we investigated if a chronic stressor has a differential effect on spatial memory in rats depending on whether it occurs during adolescence or the juvenile period. Male rats were exposed to the stress hormone corticosterone (Cort) in their drinking water, a vehicle control (2.5% ethanol), or water, for 7 days before being tested on a novel Object/Place task 6 days or 6 weeks later. Exposure to Cort or ethanol at either age impaired spatial memory at the 6-day test. The ethanol induced impairment was attenuated 6 weeks later. However, rats given Cort during adolescence, but not the juvenile period, were still impaired. Together, these results suggest that adolescence is indeed a stress-sensitive period.

Anger is often associated with approach motivation, and most self-report scales measuring trait anger tap this approach orientation. However, some research has suggested that individuals occasionally experience anger and respond with avoidance motivation. This suggests that individuals may differ in chronic tendencies toward responding to anger with avoidance. The current research introduces a new self-report instrument, the Avoidance Motivated Response to Anger Scale, designed to assess this trait. We report findings of four studies conducted with American and Polish individuals. The studies provide evidence of the scale's internal consistency, test-retest reliability, convergent validity, and discriminant validity.

The present research aimed to better understand individual differences in attitudes towards emotions with a focus on anger. We report findings of four studies conducted with American and Polish individuals. Results showed that individuals who have more positive attitudes toward anger are higher in trait anger (Studies 1–4), are more likely to think about getting revenge (Study 1), and expect that getting revenge will make them feel good (Studies 1–2). In addition, these individuals are lower in agreeableness and lower in the tendency to engage in avoidance when angered (Studies 1–4). They score lower in humility (Studies 3–4), lower in secure romantic attachment but higher in anxious and avoidance attachment (Study 3). Finally, they are more likely to believe a wide range of conspiracies (Studies 2–4). Discussion focuses on the implications of these results.
