Parent and Adolescent Responses to PovertyRelated Stress: Tests of Mediated and Moderated Coping Models

We tested several models of the associations among economic strain, life stress, coping, involuntary stress responses, and psychological symptoms in a sample of 57 parent-adolescent dyads from rural, lower-income families. Economic strain and life stress predicted symptoms for both parents and adolescents. Stressor-symptom specificity was found for parents, such that economic strain uniquely predicted depression, whereas negative life events predicted hostility. Involuntary stress responses were associated with higher levels of symptoms for both parents and the adolescent children. Secondary control coping was associated with fewer symptoms for both parents and adolescents. Results support a mediational role of coping and responses to stress during adolescence, with a shift to moderational status in adulthood. Implications of these results are discussed with regard to developmental coping theory and potential interventions with at-risk families.     

Is self special? A critical review of evidence from experimental psychology and cognitive neuroscience

Varied research findings have been taken to support the claim that humans' representation of the self is "special," that is, that it emerges from systems that are physically and functionally distinct from those used for more general purpose cognitive processing. The authors evaluate this claim by reviewing the relevant literatures and addressing the criteria for considering a system special, the various operationalizations of self, and how the studies' findings relate to the conclusions drawn. The authors conclude that many of the claims for the special status of self-related processing are premature given the evidence and that the various self-related research programs do not seem to be illuminating a unitary, common system, despite individuals' subjective experience of a unified self.     

Patterns of brain-electrical activity during declarative memory performance in 10-month-old infants

This study of infant declarative memory concurrently examined brain-electrical activity and deferred imitation performance in 10-month-old infants. Continuous electroencephalogram (EEG) measures were collected throughout the activity-matched baseline, encoding (modeling) and retrieval (delayed test) phases of a within-subjects deferred imitation task. Infants were divided into two memory performance groups based on the exhibition of ordered-recall after a 24-h delay. Whereas no group differences were found in EEG collected during encoding, performance-group differences in EEG were present during retrieval. Infants who successfully displayed ordered-recall showed a pattern of increasing EEG from baseline to task at anterior temporal scalp locations, whereas infants showing no ordered-recall displayed no changes in EEG from baseline to task. These findings are discussed with respect to the biobehavioral developments underlying declarative memory abilities.     

Is the loss of diagnosticity of the eye region of the face a common aspect of acquired prosopagnosia?

A recent study published in this journal has shown an abnormal performance at discriminating differences with respect to the eyes of unfamiliar faces in two acquired prosopagnosic patients, but preserved processing of the mouth region. Here we extend these findings by showing a similar lack of sensitivity to the eyes in the very same face matching experiment for the prosopagnosic patient PS, who also showed normal performance for detecting differences in the mouth region. These results complement previously published evidence that the patient PS presents a lack of sensitivity to diagnostic information located on the eyes of familiar faces during individual face recognition tasks. More generally, they indicate that the impaired processing of the eyes of faces is a fundamental aspect of acquired prosopagnosia that can arise following damage to different brain localizations.     

Impact of Sluggish Cognitive Tempo and Attention-Deficit/Hyperactivity Disorder Symptoms on Adults’ Quality of Life

The symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) have been linked to dysfunction in numerous life domains for both children and adults. As such, it is likely that individuals with these and other related symptoms (e.g., sluggish cognitive tempo, SCT) may also experience impaired quality of life. The current study examines the association between ADHD and SCT symptoms and quality of life (QOL) in a community sample of adults. Quality of life data collected from 983 participants (M age = 45.6 years) were analyzed primarily through a series of hierarchical multiple regressions employing SCT and ADHD symptom clusters, demographic, and anxiety and depression scale variables as predictors. Results generally supported the hypothesis that ADHD and SCT symptoms would negatively associate with QOL. Amongst the indicators, inattention and SCT emerged as the strongest predictors of low QOL. These findings underscore the negative impact of ADHD symptoms in adulthood, the independent contribution of SCT, and the importance of considering QOL in prospective research and intervention.     

Regions of the MPFC differentially tuned to social and nonsocial affective evaluation

The medial prefrontal cortex (MPFC) reliably activates in social cognition and reward tasks. This study locates distinct areas for each. Participants made evaluative (positive/negative) or social (person/not a person) judgments of pictured positive or negative people and objects in a slow event-related design. Activity in an anterior rostral region (arMPFC) was significantly greater for positive than for negative persons but did not show a valence effect for objects, and this was true regardless of the judgment task. This suggests that the arMPFC is tuned to social valence. Interestingly, however, no regions of the MPFC were found to be responsive to social information independently of valence. A region-of-interest analysis of the paraanterior cingulate cortex (pACC), previously implicated in reward processing, demonstrated sensitivity to the valence of all stimuli, whether persons or objects, across tasks. Affective evaluation may be a general function of the MPFC, with some regions being tuned to more specific domains of information (e.g., social) than are others.     

Trust

Children rely extensively on others' testimony to learn about the world. However, they are not uniformly credulous toward other people. From an early age, children's reliance on testimony is tempered by selective trust in particular informants. Three- and 4-year-olds monitor the accuracy or knowledge of informants, including those that are familiar. They prefer to seek and endorse information provided by someone who has proved accurate in the past rather than someone who has made mistakes or acknowledged ignorance. Future research is likely to pinpoint other heuristics that children use to filter incoming testimony and may reveal more generalized patterns of trust and mistrust among individual children.     

Perceptions of Sexual Orientation: A Hierarchically Restrictive Trait

Categorizing a person according to group membership (sexual orientation) attaches group stereotypes and behavioral expectations to that individual. For Study 1, students from New Mexico, United States (N?=?127) were asked to indicate the number of inconsistent behaviors it would take to change expectations about a categorized person. Study 1 revealed that sexual orientation is a hierarchically restrictive trait: for heterosexual targets, only a few inconsistent behaviors changed expectations, and for homosexual targets, many inconsistent behaviors did not change expectations. For Study 2, survey research (N?=?163) and path analyses revealed different patterns between male and female respondents for relationships between religiosity, attitudes toward homosexuals, attitudes toward sexuality, and the degree of hierarchical restrictiveness of sexual orientation.     

Memories affect mood: evidence from covert experimental assignment to positive, neutral, and negative memory recall

Memory recall has been proposed as a common and effective mood regulation strategy. Although several studies have presented results suggesting that recalling valenced memories affects subsequent mood, their designs allow for alternative interpretations of the observed effects. Two such alternatives include the reverse effect (mood effects on memory due to non-experimental assignment to memory recall condition) and demand characteristics of the experiment. We used covert experimental assignment to memory condition, asking subjects (N=314; 56% female) to recall memories that were primarily positive, neutral, or negative. Results showed the expected effect on mood (p<.002), with reported mood worst in the negative memory condition, better in the neutral condition, and best in the positive condition. These results suggest that valenced memory recall does indeed exert an effect on mood, and may do so even without the individual's awareness.     

Self-esteem moderates the response to forgiveness instructions among women with a history of victimization

The present study examined whether self-esteem would moderate women’s affect after being exposed to brief instructional interventions tapping into two dimensions of forgiveness: an interpersonal dimension focusing on forgiving the offender, and an intrapersonal dimension focusing on letting go of one’s negative affect toward the offender. The positive and negative affect of 79 women with a history of victimization was assessed after they listened to instructions for either granting forgiveness, letting go of their negative affect, or relaxation (control). Results indicated differential effects of the instructions on emotions directed toward themselves versus toward the offender. Women had more negative emotions about themselves when they received the granting forgiveness instructions, but they had greater positive emotions toward their offenders. Women’s responses were moderated by self-esteem in that there was no differential effect of the instructions among women low in self-esteem, but women high in self-esteem had a relatively positive response to the letting-go instructions and a generally negative reaction to the traditional forgiveness instructions.
