Event-Related Potential and Behavioral Measures of Attention in 5-, 7-, and 9-Year-Olds

In 2 experiments, the development of auditory selective attention in children was assessed. The participants, aged 5, 7, and 9 years, responded to target stimuli in the left ear for 1 series (ignoring the standard stimuli) and in the right ear for the other series. In Experiment 1, event-related potentials (ERPs) evoked by the auditory stimuli were recorded from frontal, central, and parietal sites. The 9-year-olds showed a greater processing negativity (Nd) to the attended channel compared with the 5-year-olds. Both 7-and 9-year-olds showed significantly larger amplitudes for the P3 component of ERPs in the attended vs. ignored condition. Behaviorally, the 5-year-olds made fewer hits and more false alarms than did older children, and the 9-year-olds made significantly more false alarms than did the 7-year-olds. The results of Experiment 2 showed that the detriment in the performance of the 9-year-olds was a result of task parameters. The inability of 5-year-olds to attend selectively appears to involve problems with the inhibition of the processing of irrelevant information and with selection of the correct response.     

Fostering Social Competence in Preschool Children Exposed to Intimate Partner Violence: Evaluating the Preschool Kids' Club Intervention

This study assessed whether participation in an intervention program enhanced social competence in 113 preschool-aged children who were exposed to intimate partner violence. Change in competence was evaluated from baseline to approximately five weeks postbaseline and compared preschool children who did and did not receive intervention services. Protective factors, such as exposure to less severe violence, were identified that predicted change in competence scores. Results indicated that children with the highest social competence pre-intervention exhibited a significant increase in their postintervention scores, if they participated in the program. The extent of this change was predicted by a higher preintervention score and exposure to less severe violence. This study indicates that even short-term intervention could result in meaningful change in key aspects of child functioning.     

Mental relaxation improves long-term incidental visual memory

Experimental evidence has linked increased arousal to enhanced memory retention. There is also evidence that procedures reducing arousal, i.e., mental relaxation, might improve memory, but conflicting results have been reported. To clarify this issue, we studied the effects of a single session of relaxation training on incidental visual long-term memory. Thirty-two relaxation-naive subjects viewed 280 slides without being told that there would be subsequent memory testing. Afterwards, subjects listened to a 12 min relaxation tape; 16 subjects relaxed by following the instructions (relaxation group), and the other 16 subjects pressed a button whenever a body part was mentioned (control group). While listening to the relaxation tape, high frequency heart rate variability (HRV) was greater and low frequency HRV was lower in the relaxation group, implying effective relaxation and increasing parasympathetic activation. The relaxation group had superior memory retention 4 weeks later (p = .004), indicating enhancement of long-term memory performance. This effect could not be explained by retroactive interference experienced in the control group because short-term memory performance immediately after the tape was slightly better in the control group. Retention of materials acquired after the relaxation session remained unaffected, suggesting relaxation has retrograde effects on memory consolidation. Our data demonstrate a favorable influence of relaxation on at least this aspect of learning. Our data also extend previous knowledge on the beneficial effects of ascending parasympathetic stimulation on memory retention in that enhanced long-term memory consolidation may also occur in the presence of central and descending parasympathetic activation triggered by willful psychomotor activity.     

Beyond intimacy: conceptualizing sex differences in same-sex friendships

This study was designed to replicate and extend prior findings that same-sex friendships of women and men are equally important but that women's friendships are more intimate. A group of adolescents and a group of adults were asked to complete an anonymous questionnaire regarding the quality of their close friendships, the degree to which they would support a close friend in times of difficulty, and the degree to which they would celebrate with a friend in times of success. Results demonstrated that both females and males saw and spoke with their close friends and were equally willing to confront and trust their close friends. Females, however, reported more desire to spend time with a close friend in times of difficulty and to celebrate with a close friend who had just experienced a positive event. Results are discussed in terms of the differing functions of women's and men's same-sex friendships and women's greater general interest in and attention to transitions in the lives of other individuals.     

The Relationship Between Racial Identity Cluster Profiles and Psychological Distress Among African American College Students

One hundred eighty‐two African American college students completed the Racial Identity Attitudes Scale. Results from the multivariate categorization scheme revealed 5 types of empirically derived racial identity attitude profiles: “dissonance internalization” (34%), “committed internalization” (30%), “cngaged internalization” (21%), “undifferentiated racial identity” (8%), and “dormant racial identity” (7%). The profiles significantly differed on Brief Symptom Inventory subscale scores.

Coping Mechanisms as Antecedents of Justice and Organization Citizenship Behaviors: A Multi-Focal Perspective of the Social Exchange Relationship

The purpose of this study was to examine approach and avoidance coping strategies in the context of a natural disaster as antecedents of justice and organizational citizenship behavior. Using a multi-focal perspective of social exchange theory, the study uses both reciprocity and rationality to enhance the theoretical underpinnings of behavior in a justice context. Survey data was collected from full-time employees who had experienced a hurricane three weeks earlier (n?=?255). The differences between approach and avoidance coping are clear in the results suggesting that coping strategy helps account for individual differences in justice perceptions. Findings demonstrated that employees who use approach coping strategies had higher perceptions of justice and higher levels of organizational citizenship behavior while employees who use avoidance coping strategies had lower perceptions of justice and lower levels of organizational citizenship behavior. This has implications for employers who could introduce coping skills training as a practical means of assisting employees in a disaster situation.     

Examining the between- and within-person effects of relative deprivation: Results from a 7-year longitudinal panel sample

Despite the extensive literature on relative deprivation theory, few studies have examined the longitudinal effects of individual- and group-based relative deprivation (IRD and GRD, respectively) on individual- and group-based outcomes, nor has research investigated the between-person and within-person effects of these constructs. Using two random intercept cross-lagged panel models, we address these oversights by estimating the between-person and average annual within-person associations IRD and GRD have with psychological distress and collective action support in a nation-wide longitudinal panel sample (N = 64,607). As expected, IRD and GRD were more strongly associated with psychological distress and collective action support, respectively, at the between-person level and contemporaneously at the within-person level. However, contrary to expectations, temporary departures in IRD and GRD predicted within-person increases in collective action support and psychological distress, respectively. These results raise questions about how and when people respond to inequality and provide the foundations for future longitudinal research.     

The structure of mood: A comparison between sleep deprivation and normal wakefulness conditions

The stability of the factor structure of mood was examined under two different experimental conditions, sleep deprivation and normal wakefulness In the first phase of the study, two different forms of a mood scale were administered to several college classes, and the ratings for each scale were intercorrelated and factored Eight interpretable factors emerged from each analysis, and the two sets of factors were highly congruent. In the second phase of the study subjects completed the mood ratings after staying awake all night or after getting a good night's rest Comparisons between the means for the two groups showed significant differences on 26 of the 44 variables included in the scale The scores for the sleep-deprived group were then intercorrelated and factored, and the factor structure was compared with the relevant factor structure obtained in the first phase of the study The results of the comparison showed that six of the eight factors appeared under both conditions of sleep deprivation and normal wakefulness Additional analysis indicated that a seventh factor appeared, but in the guise of different variables The only factor which failed to appear under sleep deprivation was elation. It was concluded that although variable ratings showed high sensitivity to the experimental operations, the basic structure of the underlying mood states remained remarkably stable The results indicate that the search for a list of basic mood states may be quite fruitful An important methodological implication was that a variable may be selected to measure a mood under various experimental operations with the assurance that the nature of the mood to be measured does not change as a result of those operations
