Encouragement and Ethnicity in African American College Students

Encouragement and ethnicity were examined in 112 African American college students attending 2 historically Black colleges and universities (HBCUs) and a predominantly White institution (PWI). Results indicated a positive relationship between Ethnic Pride and View of Others for the HBCU group and positive relationships between Ethnic Pride and the Encouragement Scale for the PWI group. Ethnic Worry was negatively correlated with the Encouragement Scale for both groups. In addition, Ethnic Discrimination was negatively correlated with Openness to Experience for the PWI group. The usefulness of conceptualizing encouragement and ethnicity together for African American college students and practice implications are discussed.     

Explicit and implicit cognition: a preliminary test of a dual-process theory of cognitive vulnerability to depression

Two studies were conducted to test a dual-process theory of cognitive vulnerability to depression. According to this theory, implicit and explicit cognitive processes have differential effects on depressive reactions to stressful life events. Implicit processes are hypothesized to be critical in determining an individual's immediate affective reaction to stress whereas explicit cognitions are thought to be more involved in long-term depressive reactions. Consistent with hypotheses, the results of study 1 (cross-sectional; N=237) showed that implicit, but not explicit, cognitions predicted immediate affective reactions to a lab stressor. Study 2 (longitudinal; N=251) also supported the dual-process model of cognitive vulnerability to depression. Results showed that both the implicit and explicit measures interacted with life stress to predict prospective changes in depressive symptoms, respectively. However, when both implicit and explicit predictors were entered into a regression equation simultaneously, only the explicit measure interacted with stress to remain a unique predictor of depressive symptoms over the five-week prospective interval.     

A goal-striving life event and the onset of hypomanic and depressive episodes and symptoms: perspective from the behavioral approach system (BAS) dysregulation theory

On the basis of the behavioral approach system (BAS) dysregulation theory of bipolar disorder, this study examined the relation between occurrence of a BAS activation-relevant life event--goal striving--and onset of hypomanic and depressive episodes and symptoms. In particular, the authors examined the relation between preparing for and completing final exams (a goal-striving event) and onset of bipolar spectrum episodes and symptoms in college students with bipolar II disorder or cyclothymia (i.e., "soft" bipolar spectrum conditions). One hundred fifty-nine individuals with either a bipolar spectrum disorder (n=68) or no major affective psychopathology (controls; n=91) were further classified on the basis of whether they were college students (i.e., completed final exams). Consistent with the BAS dysregulation theory, preparing for and completing final exams was associated with an increase in hypomanic but not depressive episodes and symptoms in individuals with a soft bipolar spectrum diagnosis. Furthermore, self-reported BAS sensitivity moderated the presence of certain hypomanic symptoms during final exams.     

Does Self-Reported Posttraumatic Growth Reflect Genuine Positive Change?

ABSTRACT— In this study, we evaluated the validity of self-reported posttraumatic growth (PTG) by assessing the relation between perceived growth and actual growth from pre- to posttrauma. Undergraduate students completed measures tapping typical PTG domains at Time 1 and Time 2 (2 months later). We compared change in those measures with scores on the Posttraumatic Growth Inventory (PTGI; Tedeschi & Calhoun, 1996 ) for those participants who reported a traumatic event between Time 1 and Time 2 ( n = 122). PTGI scores generally were unrelated to actual growth in PTG-related domains. Moreover, perceived growth was associated with increased distress from pre- to posttrauma, whereas actual growth was related to decreased distress, a pattern suggesting that perceived and actual growth reflect different processes. Finally, perceived (but not actual) growth was related to positive reinterpretation coping. Thus, the PTGI, and perhaps other retrospective measures, does not appear to measure actual pre- to posttrauma change.     

What Are Nervous Systems For?

Abstract

An underlying bias of contemporary cognitive science is that the brain and nervous system are in the business of carrying out computations and building representations. Gibson’s ecological approach, in contrast, is decidedly noncomputational and nonrepresentational. How, then, are we to construe the role of brain and nervous system? We consider this question against the backdrop of evidence for rich achievements in perception and action by agents without brains or nervous systems. If fundamental coordination of perception and action does not require a neural substrate, then what value is added in having one? And if the neural substrate is not in the representational–computational business, then what business is it in? We pursue answers grounded in the constraints of macroscopic, multicellular life and thermodynamics.
