Posterior parietal cortex (PPC) participates in the planning of visuospatial behaviors, including reach movements, in gaze-centered coordinates. It is not known if these representations encode the visual goal in retinal coordinates, or the movement direction relative to gaze. Here, by dissociating the intrinsic retinal stimulus from the extrinsic direction of movement, we show that PPC employs a visual code. Using delayed pointing and event-related functional magnetic resonance imaging, we identified a cluster of PPC regions whose activity was topographically (contralaterally) related to the direction of the planned movement. We then switched the normal visual-motor spatial relationship by adapting subjects to …

To be considered a vulnerability marker for depression, a variable should, in addition to demonstrating sensitivity and specificity, also show evidence of temporal stability (i.e., remain present in the absence of depressive symptomatology). Although many cognitive factors are associated with depression, the majority of them appear to be episode rather than vulnerability markers. This study examined cognitive organization of positive and negative interpersonal and achievement content in clinically depressed, remitted, and nonpsychiatric controls. At initial assessment, a sample of 54 clinically depressed individuals and 37 never-depressed controls completed self-report measures of positive and negative automatic thoughts and two cognitive organizational …

Heads Up!
College students who violate campus alcohol policies (adjudicated students) are at high risk for experiencing negative alcohol-related consequences and for undermining campus life. Further, college women may be especially at risk due to differential intoxication effects and sexual consequences experienced mainly by female students. Research on interventions for adjudicated students, especially adjudicated females, has been limited. One hundred and fifteen college women who received a sanction for violating campus alcohol policies participated in the study. The two hour group intervention focused on female-specific reasons for drinking and included decisional balance, goal setting and other exercises. Participants completed follow-up surveys for …
