Race and gender on the brain: Electrocortical measures of attention to the race and gender of multiply categorizable individuals.

The degree to which perceivers automatically attend to and encode social category information was investigated. Event-related brain potentials were used to assess attentional and working-memory processes on-line as participants were presented with pictures of Black and White males and females. The authors found that attention was preferentially directed to Black targets very early in processing (by about 100 ms after stimulus onset) in both experiments. Attention to gender also emerged early but occurred about 50 ms later than attention to race. Later working-memory processes were sensitive to more complex relations between the group memberships of a target individual and the surrounding social context. These working-memory processes were sensitive to both the explicit categorization task participants were performing as well as more implicit, task-irrelevant categorization dimensions. Results are consistent with models suggesting that information about certain category dimensions is encoded relatively automatically.

The changing signs in the relationships among self-efficacy, personal goals, and performance.

The common interpretation of the positive correlation among self-efficacy, personal goals, and performance is questioned. Using self-efficacy theory (A. Bandura, 1977), it was predicted that cross-sectional correlational results were a function of past performance's influence on self-efficacy, and using control theory (W. T. Powers, 1973), it was predicted that self-efficacy could negatively influence subsequent performance. These predictions were supported with 56 undergraduate participants, using a within-person procedure. Personal goals were also positively influenced by self-efficacy and performance but negatively related to subsequent performance. A 2nd study involving 185 undergraduates found that manipulated goal level positively predicted performance and self-efficacy positively predicted performance in the difficult-goal condition. The discussion focuses on conditions likely to affect the sign of the relationship among self-efficacy, goals, and performance. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Neural correlates of posttraumatic growth after severe motor vehicle accidents.

Frontal brain asymmetry has been associated with emotion- and motivation-related constructs. The authors examined the relationship between frontal brain asymmetry and subjective perception of posttraumatic growth (PTG) after severe motor vehicle accidents (MVAs). Eighty-two survivors of MVAs completed self-report measures of PTG, trait and state affect, and diagnostic interviews assessing clinical status, and underwent measurement of resting electroencephalographic activity. As predicted, increased relative left frontal activation was significantly related to PTG, even when statistically controlling for dispositional positive affect. The authors assume that approach-related motivational tendencies associated with higher relative left frontal brain activity may be involved in the process and outcome of PTG.

The reasons for turnover of information systems personnel

The study examines the effects of the individual characteristics, job type, role stressors, boundary spanning activities, career outcomes, and job characteristics on the turnover propensity of 464 information systems personnel. Results show that age, organizational level, organizational tenure, job tenure, and number of years in the computer field are negatively correlated with the intention to leave the organization. Education was found to be positively correlated with turnover intentions, and while project leaders are more likely to leave the organization, IS managers are less likely. Results also show that both role stressors (role ambiguity and role conflict) and boundary spanning activities are positively correlated with turnover intentions, and that job involvement, career plateau, promotability, salary, organizational commitment, job satisfaction, satisfaction with progress, promotion, pay, status, and projects are negatively correlated while career opportunity is positively correlated with turnover intentions. Finally, all job characteristics are negatively correlated with turnover intentions. Implications of the results for practice and research are offered.     

Tripartite dimensions of emotion in a child clinical sample: Measurement strategies and implications for clinical utility.

Several measurement strategies to assess the tripartite model of emotion in child and adolescent samples have been developed. However, no studies have comparatively examined the most suitable strategies in clinical samples of children and adolescents. This study involved the evaluation of 2 distinct measures of tripartite constructs relative to anxiety and depression criterion variables in a clinical sample of 226 children in Grades 1 through 12. Results indicated that the measures performed similarly overall, but some differences were pronounced enough to suggest that the measures indexed slightly different aspects of the same constructs. These differences appear consistent with the scale design of each instrument. Implications for measurement of these constructs in future research are highlighted.

Neural correlates of age-related declines in the formation and realization of delayed intentions.

Neural correlates of age-related declines in prospective memory were studied by using event-related brain potentials (ERPs) in a task in which individuals formed and later realized simple intentions. The behavioral data revealed that prospective responding was less accurate and slower in older than in younger adults. The electrophysiological data revealed age-related differences in the amplitude of modulations of the ERPs associated with the encoding of intentions, the detection of cues, and disengagement from the ongoing activity. These findings support the hypothesis that age-related declines in prospective memory result from a reduction in the efficiency with which older adults encode intentions and detect cues.

Neural Basis for Verb Processing in Alzheimer's Disease: An fMRI Study.

Patients with probable Alzheimer's disease (AD) have difficulty understanding verbs. To investigate the neural basis for this deficit, the authors used functional magnetic resonance imaging to examine patterns of neural activation during verb processing in 11 AD patients compared with 16 healthy seniors. Subjects judged the pleasantness of verbs, including MOTION verbs and COGNITION verbs. Healthy seniors and AD patients both activated posterolateral temporal and inferior frontal regions during judgments of verbs. These activations were relatively reduced and somewhat changed in their anatomic distribution in AD patients compared with healthy seniors, particularly for the subcategory of MOTION verbs, but AD patients showed minimal activation in association with COGNITION verbs. These findings imply that poor performance with verbs in AD is due in part to altered activation of the large-scale neural network that supports verb processing.

Behavioral correlates of peer exclusion and victimization of East Asian American and European American young adolescents.

The present study examined behavioral correlates of peer exclusion and victimization among sixth-grade European and East Asian American young adolescents, with an emphasis on aggressive and socially withdrawn behaviors. Concurrent and short-term longitudinal (over 1 academic year) associations between behavior and the distinct forms of peer adversity (victimization/exclusion) were assessed. Results varied by gender and ethnicity and suggested that social withdrawal was associated with exclusion, whereas aggression was associated with victimization. Interactions between gender and aggression predicted peer victimization after controlling for prior victimization. Extremely aggressive girls were more likely to be victimized than nonaggressive girls. Interactions between gender, ethnicity, and behavior predicted exclusion, controlling for prior exclusion. Extremely withdrawn European American girls were less excluded than nonwithdrawn European American girls. Universals emerged in the prediction of exclusion from withdrawal for all other groups and from aggression for all four groups. These results highlight the importance of considering ethnicity and gender in the links between different behaviors and the distinct forms of peer adversity.

Impact of valence and age on olfactory induced brain activation in healthy women.

The aim of the present study was to assess the effect of age on cerebral correlates of olfactory induced negative emotions. We investigated 15 healthy women (aged 21–47) in a functional MRI (fMRI) study during passive smelling of one negative odor (rotten yeast) and two control conditions presenting a neutral odor (vanilla) and odorless ambient air. Besides odor-specific differences in ratings of valence (yeast less pleasant than vanilla and air), intensity (yeast more intense than vanilla and air), and arousal (yeast more arousing than vanilla and air), self-ratings verified the intended mood induction effect: subjects experienced more disgust during yeast stimulation compared to ambient air and vanilla. Along with the superior temporal cortex, medial, and lateral orbitofrontal activations were found to discriminate between negative and neutral olfactory stimulation (yeast and vanilla) directly. Activations of the dorsolateral prefrontal cortex and the caudate were correlated with age and showed stronger valence-related responses (yeast vs. vanilla) in younger compared to older women. Stronger BOLD signals within the anterior cingulate gyrus, insula and motor areas were found during negative compared to neutral stimulation and are considered to represent an attempt to down-regulate the strong emotional experience and the organisms' preparation for withdrawal, respectively. Our results stress the role of orbitofrontal and superior temporal brain regions in odor-related valence coding and stress the necessity to consider age as a modulating factor for further studies, even in relatively young samples.

Psychological aspects of asthma.

Asthma can be affected by stress, anxiety, sadness, and suggestion, as well as by environmental irritants or allergens, exercise, and infection. It also is associated with an elevated prevalence of anxiety and depressive disorders. Asthma and these psychological states and traits may mutually potentiate each other through direct psychophysiological mediation, nonadherence to medical regimen, exposure to asthma triggers, and inaccuracy of asthma symptom perception. Defensiveness is associated with inaccurate perception of airway resistance and stress-related bronchoconstriction. Asthma education programs that teach about the nature of the disease, medications, and trigger avoidance tend to reduce asthma morbidity. Other promising psychological interventions as adjuncts to medical treatment include training in symptom perception, stress management, hypnosis, yoga, and several biofeedback procedures.
