The affective consequences of visual attention in preview search

Comparisons of emotional evaluations of abstract stimuli just seen in a two-object visual search task show that prior distractors are devalued, as compared with prior targets or novel items, perhaps as a consequence of persistent attentional inhibition (Raymond, Fenske, & Tavassoli, 2003). To further explore such attention-emotion effects, we measured search response time in a preview search task and emotional evaluations of colorful, complex images just seen therein. On preview trials, the distractors appeared 1,000 msec before the remaining items. On no-preview trials, all the items were presented simultaneously. A single distractor was then rated for its emotional tone. Previewed distractors were consistently devalued, as compared with nonpreviewed distractors, despite longer exposure and being associated with an easier task. This effect was observed only in the participants demonstrating improved search efficiency with preview, but not in others, indicating that the attentional mechanisms underlying the preview benefit have persistent affective consequences in visual search.     

Culture, trauma, and wellness: a comparison of heterosexual and lesbian, gay, bisexual, and two-spirit native americans

In a community-based sample of urban American Indian and Alaska Native adults, 25 lesbian, gay, bisexual, and two-spirit participants were compared with 154 heterosexual participants with respect to sociodemographic characteristics, Native, cultural participation, trauma, physical and mental health, and substance use. Compared with their heterosexual counterparts, two-spirit participants reported higher rates of childhood physical abuse and more historical trauma in their families, higher levels of psychological symptoms, and more mental health service utilization. Two-spirit participants reported differences in patterns of alcohol use and were more likely to have used illicit drugs other than marijuana. Discussion and recommendations for health promotion interventions and future research are presented in consideration of an "indigenist" health model and the multiple minority status of two-spirit people.     

The role of joint attention in the development of infants' play with objects

Year-old infants' play was scored within and outside joint attention with mother and when alone for four levels of maturity: stereotypical, inappropriate relational, appropriate relational, functional. Maternal sensitivity within joint attention was rated on two measures: following infants' interests and scaffolding infants' activities. Infants' play was more advanced with mother than when alone. With mother, infants had more functional and appropriate relational play within joint attention and more stereotypical play outside joint attention, indicating more advanced play within joint attention and more immature play outside joint attention. Functional play within joint attention, but not outside joint attention, correlated with functional play when alone. Mothers' ability to scaffold infants' activities within joint attention may be particularly facilitative to infants' advanced play.     

A multimethod examination of the stability of depressive symptoms in childhood and adolescence

In an 8-wave, 2-cohort longitudinal study, children and adolescents were followed from the fall of 5th grade to the spring of 8th grade. Participants (N = 1,269), their parents, and peers completed reports of depressive symptoms at 6-month intervals. The use of a 2-group latent variable autoregressive model to examine the stability of depressive symptomatology revealed several trends. First, the 6-month stability of depressive symptoms was high for boys and girls. Second, the stability of depressive symptomatology was lower between the spring of 6th grade and the fall of 7th grade than during any other point in the study. Finally, the stability of depressive symptoms did not differ with respect to gender.     

Infants' perception of information along object boundaries: concavities versus convexities

Object parts are signaled by concave discontinuities in shape contours. In seven experiments, we examined whether 5- and 6 1/2-month-olds are sensitive to concavities as special aspects of contours. Infants of both ages detected discrepant concave elements amid convex distractors but failed to discriminate convex elements among concave distractors. This discrimination asymmetry is analogous to the finding that concave targets among convex distractors pop out for adults, whereas convex targets among concave distractors do not. Thus, during infancy, as during adulthood, concavities appear to be salient regions of shape contours. The current study also found that infants' detection of concavity is impaired if the contours that define concavity and convexity are not part of closed shapes. Thus, for infants, as for adults, concavities and convexities are defined more readily in the contours of closed shapes. Taken together, the results suggest that some basic aspects of part perception from shape contours are available by at least 5 months of age.     

Optimism in close relationships: How seeing things in a positive light makes them so

Does expecting positive outcomes--especially in important life domains such as relationships--make these positive outcomes more likely? In a longitudinal study of dating couples, the authors tested whether optimists (who have a cognitive disposition to expect positive outcomes) and their romantic partners are more satisfied in their relationships, and if so, whether this is due to optimists perceiving greater support from their partners. In cross-sectional analyses, both optimists and their partners indicated greater relationship satisfaction, an effect that was mediated by optimists' greater perceived support. When the couples engaged in a conflict conversation, optimists and their partners saw each other as engaging more constructively during the conflict, which in turn led both partners to feel that the conflict was better resolved 1 week later. In a 1-year follow-up, men's optimism predicted relationship status. Effects of optimism were mediated by the optimists' perceived support, which appears to promote a variety of beneficial processes in romantic relationships.     

Adverse psychological outcomes in colorectal cancer screening: does health anxiety play a role?

People who are anxious about their health are more likely to misinterpret health information as personally threatening and less likely to be reassured by medical investigations that show they are free from disease. Consequently, health anxious people would be expected to react more adversely to cancer screening, but this possibility has rarely been explored. The moderating role of health anxiety on the psychological impact of participating in colorectal cancer screening was examined among a sub-sample of 3535 participants in a large, community-based trial of colorectal cancer screening in the UK. The screening modality was flexible sigmoidoscopy, which examines the bowel for pre-cancerous polyps. It was predicted that health anxiety would be associated with more worry about cancer before screening, a greater increase in worry if polyps were detected, and less reassurance after a clear result. As expected, health anxious participants were more anxious and more worried about bowel cancer both before and after screening. However, they experienced greater reductions in anxiety and worry about cancer following the examination. They reported lower levels of reassurance following screening, but also expressed more positive reactions to the experience. The positive psychological benefits of attending medical investigations should be examined in future work, because this may go some way towards explaining why health anxious people repeatedly seek medical interventions.     

Family structure and age at menarche: a children-of-twins approach

Girls who grow up in households with an unrelated adult male reach menarche earlier than peers, a finding hypothesized to be an evolutionary strategy for families under stress. The authors tested the alternative hypothesis that nonrandom selection into stepfathering due to shared environmental and/or genetic predispositions creates a spurious relation between stepfathering and early menarche. Using the unique controls for genetic and shared environmental experiences offered by the children-of-twins design, the authors found that cousins discordant for stepfathering did not differ in age of menarche. Moreover, controlling for mother's age of menarche eliminated differences in menarcheal age associated with stepfathering in unrelated girls. These findings strongly suggest selection, and not causation, accounts for the relationship between stepfathering and early menarche.     

Characteristics of successful fakers versus unsuccessful fakers: is empathy, intelligence, or personality associated with faking PTSD on the MMPI-2?

Moyer, Burkhardt, and Gordon found in 2002 that some individuals could fake PTSD on the MMPI-2. In light of these results, a follow-up study was conducted to assess whether attributes such as empathy, intelligence, subjectivity, or insightfulness influenced ability to fake a PTSD profile on the MMPI-2. 35 subjects from the previous study were divided into two groups, successful fakers and unsuccessful fakers. Analysis indicated no significant differences between groups on the measures of empathy or intelligence. However, a significant difference was found between groups on the Schizophrenia and Cynicism scales and falling just short of significance on the Hypochondriasis scale. These results suggested that individuals able to fake PTSD are more insightful and less subjective, which makes them better at role-playing.     

Depressive Symptomatology among HIV-Positive Women in the Era of HAART: A Stress and Coping Model

Objective: An enhanced stress and coping model was used to explain depression among HIV-positive women in healthcare and community settings where highly active anti-retroviral treatment (HAART) was commonplace. Method: HIV-infected women in four cities (N=978) were assessed, cross-sectionally, for mental and physical health, stress, social support, and other background factors. Results: Self-reported level of depressive symptomatology was high. Number of physical symptoms, illness intrusiveness, and perceived stress were positively associated with depressed mood, while coping self-efficacy and social support were negatively associated. Stress mediated the effect of health status on depression and coping self-efficacy mediated the effect of psychosocial resources on depression. Our enhanced stress and coping model accounted for 52% of variance in depressive symtpomatology. Conclusions: Interventions focused on improving coping self-efficacy, bolstering social supports, and decreasing stress in the lives of HIV-positive women may help to reduce the negative effects of HIV disease on mood.
