The relationship between attentional blink and psychological refractory period.

This study examined the relationship between attentional blink (AB) and psychological refractory period (PRP) using a conventional AB procedure combined with a requirement of speeded responses to the second target (T2). Experiments 1 and 2 showed that, as with PRP, memory retrieval of targets is not a necessary condition for the occurrence of AB in terms of accuracy and that AB occurred in the speed data. Experiment 3 further indicated that the PRP-like speed data were not due to the first target serving as a warning signal that triggered preparation of responses to T2. Experiment 4 manipulated T2 stimulus intensity to be normal or low. Results showed an underadditive interaction between stimulus intensity and lag position in the speed data, whereas an overadditive interaction was found in the accuracy data, suggesting 2 sources of interference leading to AB: the single-channel bottleneck and resource-limited visual-processing capacity.

Cultural psychology, a new look: Reply to Bond (2002), Fiske (2002), Kitayama (2002), and Miller (2002).

M. H. Bond (2002) (see record 2002-00183-002), A. P. Fiske (2002) (see record 2002-00183-003), S. Kitayama (2002) (see record 2002-00183-004), and J. G. Miller (2002) (see record 2002-00183-005) joined D. Oyserman, H. M. Coon, and M. Kemmelmeier (2002) (see record 2002-00183-001) in highlighting limitations of the individualism-collectivism model of culture. Concern is warranted; nevertheless, individualism-collectivism helps structure discourse on the influence of culture on the mind. To avoid level-of-analysis entanglements, Oyserman et al propose an integrative model that includes distal, proximal, and situated cultural features of societies and internalized models of these features, highlights the importance of subjective construal, and uses evolutionary perspectives to clarify the basic problems cultures address. Framed this way, it is clear that, depending on situational requirements, both individualism- and collectivism-focused strategies are adaptive; thus, it is likely that human minds have adapted to think both ways.

Clinical adolescent psychology: What it is, and what it needs to be.

This commentary on the special section on clinical adolescent psychology (G. Holmbeck & P. Kendall, 2002) reviews and critiques the conceptual and empirical articles that this compilation comprises. As articulated in the conceptual contributions to this collection, two fundamental principles should guide research on the etiology, prevention, and treatment of psychological disorder and dysfunction during adolescence: First, drawing on the field of developmental psychopathology, the study of clinical adolescent psychology should focus on the trajectories of disorder that precede, characterize, and follow adolescence. Second, drawing on the literature on normative adolescent development, the study of clinical adolescent psychology must proceed with an explicit recognition of the unique biological, cognitive, psychosocial, and contextual features that define adolescence as a developmental period. Although the study of clinical adolescent psychology, as evidenced by this collection of articles, is appropriately grounded in the broader enterprise of developmental psychopathology, less progress has been made with respect to die integration of the study of clinical phenomena in adolescence with the study of normative adolescent development.

Couples coping with congestive heart failure: Role and gender differences in psychological distress.

Psychological distress and marital quality were assessed with male (n=128) and female (n=49) congestive-heart-failure (CHF) patients and their spouses. Hopkins Symptom Check List-25 scores were in the distressed range for 57% of patients and 40% of spouses. This role difference was greater for men than for women, and a gender difference (more distress in women than men) was greater for spouses than for patients. The patient's distress, but not the spouse's, reflected the severity of the patient's illness, and distress for both partners correlated negatively with ratings of marital quality. Female-patient couples reported better relationship quality than male-patient couples, however, and a mediation analysis indicated that the gender difference in spouse distress could be explained by marital quality. Results highlight the contextual nature of CHF distress and suggest that role differences in distress vary by gender. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychological impact of benign breast biopsy: A longitudinal, comparative study.

The impact of benign breast biopsy (BBB) on distress and perceptions of risk for breast cancer (BC) was examined. Interviews were conducted with 100 women shortly after notification of biopsy results and 4 and 8 months post-BBB. Compared with matched healthy comparison (HC) women without BBB, the BBB group evidenced greater BC-specific distress at baseline. BC-specific distress declined after BBB, remaining elevated relative to the HC group at the 8-month follow-up. Dispositional (optimism, informational coping style), demographic (education), clinical (family history of BC), and cognitive (BC risk perception) variables were associated with baseline levels of BC-specific distress or persistence of distress. Results support the monitoring process model (S. M. Miller, 1995) and the cognitive social health information processing model (S. M. Miller, Y. Shoda, & K. Hurley, 1996).

Exchange Relationships: Examining Psychological Contracts and Perceived Organizational Support.

The authors surveyed 347 public sector employees on 4 measurement occasions to investigate the conceptual distinctiveness of the psychological contract and perceived organizational support (POS) and how they are associated over time. Results support the distinctiveness of the 2 concepts. In terms of their interrelationships over time, by drawing on psychological contract theory the authors found little support for a reciprocal relationship between POS and psychological contract fulfillment. Under an alternative set of hypotheses, by drawing on organizational support theory and by separating psychological contract fulfillment into its 2 components (perceived employer obligations and inducements), the authors found that perceived employer inducements were positively related to POS, which, in turn, was negatively related to perceived employer obligations. The results suggest that POS and the components of psychological contract fulfillment are more important in predicting organizational citizenship behavior than psychological contract fulfillment.

Intergenerational Family Conflict and Coping Among Hmong American College Students.

Problem solving and social support, as different styles of coping with intergenerational family conflict, were examined among 86 Hmong American college students. Problem solving and social support were hypothesized to differentially moderate the effects of family conflict on psychological adjustment. Furthermore, the effects of attributions of blame on the adjustment of Hmong American college students were examined. Results indicate that social support buffered and problem solving enhanced the negative effects of family conflict on symptoms of distress but not on affect. Additionally, there were significant interaction effects between family conflict and self-blame on distress. Specifically, students who were more likely to blame themselves reported higher levels of distress. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychological and Physiological Adaptations to Sperm Competition in Humans.

Postcopulatory competition between males, in the form of sperm competition, is a widespread phenomenon in many animal species. The extent to which sperm competition has been an important selective pressure during human evolution remains controversial, however. The authors review critically the evidence that human males and females have psychological, behavioral, and physiological adaptations that evolved in response to selection pressures associated with sperm competition. The authors consider, using evidence from contemporary societies, whether sperm competition is likely to have been a significant adaptive problem for ancestral humans and examine the evidence suggesting that human males have physiological and psychological mechanisms that allow for "prudent" sperm allocation in response to variations in the risk of sperm competition.

Psychological Stress Tasks in the Prediction of Blood Pressure Level and Need for Antihypertensive Medication: 9-12 Years of Follow-Up.

Increased blood pressure (BP) reactivity to subtypes of psychological stimuli may differentially predict the development of future BP elevation or hypertension. The authors present the 9-12-year follow-up results of 82 (86%) of 95 male participants with different BP levels. They were healthy, untreated, and age-matched volunteers from a routine health checkup carried out on all 35-, 40-, and 45-year-olds from a medium-sized city. Intra-arterial systolic blood pressure (SBP) during the psychological tasks improved the prediction of future casual SBP and noninvasive 24-hr ambulatory SBP compared with predictions from casual diagnostic measurements. Diastolic blood pressure (DBP) was very useful when added to casual DBP in predicting the need for antihypertensive medication. Reactivity to active tasks especially predicts the need for antihypertensive medication. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Finances and Well-Being: A Dynamic Equilibrium Model of Resources.

This study of 513 Dutch farmers tested a dynamic equilibrium model of resources (an extension of the conservation of resources theory; S. E. Hobfoll, 1989, 1998, 2001). With structural equation modeling, the advantages of a 3-wave longitudinal design were comprehensively used, such as addressing bidirectional causal effects and within-individual vs. between-individual change. This allowed for a careful analysis of the management function of resources in the stress process. Results showed that well-being had stronger within-person stability than finances. Increased levels of financial problems temporarily increased psychological distress but not self-reported illness. Conversely, farmers with higher stable baselines of psychological distress also had higher baselines of self-reported illness and experienced more negative changes in their financial situation.
