Long-term ability to interpret facial expression after traumatic brain injury and its relation to social integration

There is considerable evidence that individuals with traumatic brain injury (TBI) experience problems interpreting the emotional state of others. However, the functional implications of these changes have not been fully investigated. A study of 13 individuals with severe TBI and an equal number of matched controls found that TBI participants had significantly more difficulty interpreting facial expression and matching emotions to social situations. A significant relationship was also established between social integration and ability to interpret facial expression for TBI participants. These results support the inclusion of therapy targeting this area within rehabilitation programs for individuals with TBI.     

Examining the components of children's peer liking as antecedents of school adjustment

Children's social interactions with their peers influence their psychosocial adjustment; consequently, the relationship between class‐wide peer liking, same‐gender peer liking, and school adjustment was explored in two age groups. Peer liking was analysed using the social relations model (SRM). In Study 1, 205 children (103 female and 102 male, M_age= 7.15, SD= 7 months) completed measures of peer liking and school adjustment, and teachers completed the Short‐Form Teacher Rating Scale of School Adjustment (Short‐Form TRSSA). In Study 2, 197 children (98 female and 90 male, M_age= 9.87, SD= 5.9 months) completed measures of peer liking and school adjustment. Both studies yielded evidence of reciprocal liking and individual differences in the ratings of liking awarded to, and elicited from, both peer groups. Multigroup path analysis, with groups created according to gender, revealed that elements of liking predicted different aspects of school adjustment with some variation according to age and gender. Together, these findings suggest that the SRM can be used to examine peer liking and underscore the importance of children's peers for school adjustment.     

Cognitive models of stereotype change (4): Motivational and cognitive influences

Three experiments investigating the effects of cognitive and motivational factors on stereotype change are reported. Trait ratings in all three experiments showed there to be greater stereotype-change when stereotype-inconsistent information was dispersed across many group members than when it was concentrated in only a few. A sorting task (Experiment 1) indicated that, in the concentrated conditions the stereotype disconfirmers were more strongly isolated from the rest of the group than in the dispersed conditions. Free recall protocols (Experiment 2) showed greater memory for the target exemplars when subjects anticipated interaction with a group member than when no interaction was anticipated. The questions subject chose to ask target group exemplars were also influenced by anticlpated future interaction. Subjects chose more stereotype-inconsistent questions when interactian was anticipated than when no interaction was anticipated. Experment 3 showed the impact of stereotype-inconsistent information to be greater when expectancies for the stereotyped group are weaker A cued-recall task yielded evidence of spontaneous subtyping. All these studies support the subtyping model, even in the presence of cognitive and motivational factors that might be expected to impede stereotype change.     

Cognitive models of stereotype change: (2) Perceptions of homogeneous and heterogeneous groups

The reported study compared change in stereotypic perceptions of homogeneous and heterogeneous groups, when subjects were presented with a pattern of stereotype-inconsistent information that was either concentrated in two extreme group members or dispersed across six members. Results pro vided some support for the ‘conversion’ model (in which stereotypes change in response to salient instances) in the case of a homogeneous group, where stereotypical responding was lower in concentrated than dispersed conditions. In the heterogeneous-group conditions, there was no effect of pattern. In addition, subjects' estimates of stereotype-consistent information were higher, and of inconsistent information were lower, and they perceived more members as typical, and fewer as atypical, when the target group was heterogeneous versus homogeneous. There was also support for the ‘subtyping’ model (in which disconfirming individuals are isolated from other group members) in the concentrated conditions. A theoretical account of these findings is given in terms of stereotype change via salience for homogeneous groups, and the need to integrate research on cognitive models of stereotype change and perceived group variability.     

Social categorization and person memory: The pervasiveness of race as an organizing principle

Two studies investigated the pervasiveness of race as a social categorization and whether the organization of information around racial categories is sensitive to contextual factors. Both studies measured accentuation effects (more intra- than inter-race errors) and own-group bias (fewer confusions between own- than other-group members) in person memory, using the paradigm developed by Taylor, Fiske, Etcoff and Ruderman (1978). Experiment 1 studies the generalization of these effects across ethnic group membership (black/white) and topic (categorization-relevant/irrelevant) in a 2 × 2 [× 4] between-subject design, with type of error as a repeated measure. There was a highly significant accentuation effect, which was not affected by either topic or group membership. Experiment 2, using white subjects only, manipulated anticipated future interaction/no interaction, which affected overall accuracy/error rate, but not the strong accentuation effect. Neither study found any support for an own-group bias. Results are discussed in terms of the automaticity of race as a basis for social categorization.     

Selective attention and secondary message analysis: A reconsideration of Broadbent's filter model of selective attention

If the type of channel sharing which Broadbent (1958) hypothesized for low information messages also occurs with high information verbal messages, then his filter model is an adequate model of the selective attention process. Analysis which proceeds by a hierarchy of tests and the fluctuating redundancy of primary prose messages can together account for the characteristics of secondary message detection. This hypothesis was tested using four levels of redundancy in the primary message, and two types of secondary message targets, requiring analysis to two different levels in the hierarchy of tests for detection. It was predicted that there should be more target detection as redundancy increased, and more detection of the targets requiring the lower level of analysis than of those requiring the higher. The predictions were confirmed with the exception that the higher level targets were detected with equal frequency at all levels of redundancy. A possible reason for this is suggested.     

Heart-beat perception, panic/somatic symptoms and anxiety sensitivity in children

There is considerable evidence implicating heart-beat perception (HBP) accuracy and anxiety sensitivity (AS) in the development of panic in adults. However, to date there have been no studies exploring the association between HBP, AS and childhood panic/somatic symptoms. Seventy-nine children aged 8 to 11 years completed a mental tracking paradigm (Psychophysiology 18 (1981) 483) to assess HBP, the Children's Anxiety Sensitivity Index (J Clin Chil Psychol 20 (1991) 162) and the Screen for Childhood Anxiety Related Emotional Disorders (J Am Acad Child Adoles Psych 38 (1999) 1230). Those with good HBP (n = 7, 9%) had significantly higher panic/somatic symptoms (t = -1.71, P < 0.05), and AS (t = -2.16, P < 0.02) than those with poor HBP. There were no effects of age, sex or BMI on HBP. Those with high levels of panic/somatic symptoms were seven times more likely to have good HBP and had AS scores 1 S.D. higher than the remainder of the sample. Multivariate analyses revealed that these two phenotypes had independent associations with high panic/somatic symptoms. These results extend the literature on HBP and panic and suggest that in children, as in adults, increased panic/somatic symptoms are associated with enhanced ability to perceive internal physiological cues, and fear of such sensations.     

The Development and Validation of a Personological Measure of Work Drive

Using six studies based on 23,823 individuals in diverse settings, we developed and validated a personality measure of Work Drive—a disposition to work long hours and extend oneself for one's job. The factor structure was confirmed in four settings. Work Drive was related to job performance showing incremental validity beyond cognitive aptitude and Big Five personality traits in five validation studies. It predicted academic performance at six different grade levels, even beyond Big Five traits. Construct validity was examined via work values, job involvement, normal personality scales, satisfaction measures, and cognitive ability. Little adverse impact was found. Occupational groups differed on Work Drive. Overall validity and areas of application were discussed.     

Understanding multiple dimensions of compensation satisfaction

We conducted meta-analyses of multiple dimensions of compensation satisfaction. An examination of 213 samples from 182 studies yielded several interesting findings of importance to practice and future research. We examined the relationships among four dimensions of compensation satisfaction (pay level, pay raises, benefit level, pay structure and administration satisfaction), and found that the three dimensions related to direct pay are highly related to one another. The relationships between benefits and the three direct pay dimensions were modest. We also analyzed antecedents, correlates, and consequences of the four compensation satisfaction dimensions. The antecedents of pay raise satisfaction have received the most attention, and our results indicate that both perceptual (e.g., perceptions of the basis for a pay raise) and objective (i.e., the amount of the pay raise) antecedents play roles in determining pay raise satisfaction. Previous research on the relationship between employee costs for benefits and benefit satisfaction have been inconclusive. The meta-analysis yields a modest, negative relationship between employee costs and benefit satisfaction. Additional results provide the foundation for our discussion of the current state of research in these areas, recommendations for practice, and suggestions for future research.     

Attention orienting effects of hesitations in speech: evidence from ERPs

Filled-pause disfluencies such as um and er affect listeners' comprehension, possibly mediated by attentional mechanisms (J. E. Fox Tree, 2001). However, there is little direct evidence that hesitations affect attention. The current study used an acoustic manipulation of continuous speech to induce event-related potential components associated with attention (mismatch negativity [MMN] and P300) during the comprehension of fluent and disfluent utterances. In fluent cases, infrequently occurring acoustically manipulated target words gave rise to typical MMN and P300 components when compared to nonmanipulated controls. In disfluent cases, where targets were preceded by natural sounding hesitations culminating in the filled pause er, an MMN (reflecting a detection of deviance) was still apparent for manipulated words, but there was little evidence of a subsequent P300. This suggests that attention was not reoriented to deviant words in disfluent cases. A subsequent recognition test showed that nonmanipulated words were more likely to be remembered if they had been preceded by a hesitation. Taken together, these results strongly implicate attention in an account of disfluency processing: Hesitations orient listeners' attention, with consequences for the immediate processing and later representation of an utterance.
