Moderators of the relationships between coworkers' organizational citizenship behavior and fellow employees' attitudes

The authors developed and tested the prediction that the relationship hetween coworkers' organizational citizenship behaviors (OCBs) and fellow employees' attitudes depends on the supervisors' abusiveness. Results of a longitudinal study using data collected from 173 supervised employees at 2 points in time (separated by 7 months) suggested that coworkers' OCB was positively related to fellow employees' job satisfaction and affective commitment when abusive supervision was low. However, when abusive supervision was high, coworkers' OCB was negatively related to job satisfaction and was unrelated to organizational commitment. The results of a 2nd study were consistent with the idea that the attributions employees make for their coworkers' OCB explains the moderating effect of abusive supervision on the relationship between coworkers' OCB and job satisfaction.     

Increasing differentiation of women and men: gender trait analysis 1974-1997

Analysis of the responses of some 4,000 college students showed increasing differentiation in the ratings of gender characteristics of typical women and men, especially with regard to feminine traits. Roughly similar patterns were observed in five other studies using the same gender traits. All studies showed continued or increased sex typing on affectionate and sympathetic. In the present study women became more feminine, and males became less, on all but one of the feminine traits. This increasing differentiation of women and men is not consistent with predictions from the sociocultural model; they are more consistent with those of the evolutionary model.     

Vicarious responses to pain in anterior cingulate cortex: Is empathy a multisensory issue?

Results obtained with functional magnetic resonance imaging show that both feeling a moderately painful pinprick stimulus to the fingertips and witnessing another person’s hand undergo similar stimulation are associated with common activity in a pain-related area in the right dorsal anterior cingulate cortex (ACC). Common activity in response to noxious tactile and visual stimulation was restricted to the right inferior Brodmann’s area 24b. These results suggest a shared neural substrate for felt and seen pain for aversive ecological events happening to strangers and in the absence of overt symbolic cues. In contrast to ACC 24b, the primary somatosensory cortex showed significant activations in response to both noxious and innocuous tactile, but not visual, stimuli. The different response patterns in the two areas are consistent with the ACC’s role in coding the motivational-affective dimension of pain, which is associated with the preparation of behavioral responses to aversive events.     

The role of perceived specificity level of failure events in self-enhancement and in constructive self-criticism

Three studies tested the role played by perceived specificity level of failures in self-enhancement and in constructive self-criticism. The first study demonstrated that perceived specificity level of events can serve as a self-protection mechanism (N = 137). The second study, based on retrospective reports of past failures and their implications, showed that perception of failures as specific induced a higher level of constructive self-criticism (N = 171). The third study tested reactions to failures induced in the laboratory. It was found that self-improvement processes are more pronounced and negative emotional reaction is weaker in failures that are specific (shape perception test) than in those that are global (intelligence test). Statistical control over perceived severity of the failure diminished the difference between the two conditions in negative emotional reaction but not in self-improvement (N = 84).     

Configural processing in the perception of eye-gaze direction

Traditional accounts of gaze perception emphasise the geometric or configural cues present in the eye; the position of the iris in relation to the corner of the eye, for example. This kind of geometric account has been supported, in part, by findings that gaze judgments are impaired in faces rotated through 180 degrees, a manipulation known to disrupt the processing of relations between facial elements. However, studies involving this manipulation have confounded inversion of the face context with inversion of the eye region. The effects of inversion might therefore have been caused by a disruption of the computation of gaze direction from the eye region itself and/or a disruption of the influence that face context might exert on gaze processing. In the experiment reported here we independently manipulated eye orientation and the orientation of the face context, and measured participants' sensitivity to gaze direction. Performance was severely affected by inversion of the eyes, regardless of the orientation of the face, whereas face inversion had no significant effect on gaze sensitivity. Previous reports of a face-inversion effect on gaze perception can therefore be attributed to inversion of the eye region itself which, we suggest, disrupts some form of configural or relational processing that is normally involved in the computation of eye-gaze direction.     

'In sickness and in health': the development of alternative discourses in work with families with parental illness

This paper outlines the development of clinical understanding and a clinical model for working with families with parental physical illness. The lens of gender to explore clinical process reveals blind spots and can uncover alternative perspectives on parental illness. The authors look at the very different needs of children and parents for coherent explanations. The impact of this way of working on therapists and the importance of reflecting teams, as part of the process of working collaboratively with families, are addressed.     

Escalation in groups: Focus on information sampling

The purpose of this experiment was to examine if groups escalate more than individuals when information is not distributed to all group members. The experiment also attempted to replicate Bazerman, Beekun, and Schoorman's (1992) findings, that participants with high responsibility escalate more than participants with low responsibility. The task was a modified version of the Heeley Store Case (Bazerman et al., 1992). The dependent measures fell into three categories: rewards, appropriateness of layoff/demotion, and forecasted future performance. The results showed little support for the hypotheses. First, high responsibility participants escalated significantly more than low responsibility candidates for only one of the six measures. This may have been due to the fact that all participants felt responsible for their decisions. For the other dependent variables, the effect was either not significant or in the wrong direction. Second, no significant interaction was found between responsibility and decision-making context (individual, groups with all shared information, and groups with shared and unshared information). We then analyzed the data using a measure of felt responsibility as a covariate. The interaction between felt responsibility and decision-making context was significant only for layoff decision. For all of the other measures, no significant interaction was found. One possible reason why our hypotheses were not supported may have been that the groups felt a diffusion of responsibility. Larger groups may have also demonstrated the effects of group processes more effectively. No clear conclusions can be made regarding the influence of information sampling on escalation. An earlier version of this paper was presented at the 1998 meetings of the American Psychological Society.     

Reexamining Bases of Power From an Attributional Perspective1

Four replications of Rodrigues' (1995) study on genotypical similarities of Raven's (1965) power taxonomy are reported. Rodrigues found that compliance induced by reward, informational, and referent power is perceived as more internal and controllable than compliant behavior induced by expert, legitimate, and coercive power. The replications included 4 new aspects: (a) subjects are highly ego-involved in the hypothetical situation presented; (b) subjects are actors rather than observers; (c) subjects are from another culture; and (d) subjects are asked to play the role of a supervisor and apply sanctions to the person who complied as a result of the influence attempt, thus affording an empirical testing of Weiner's (1995) thought-affect-action sequence when responsibility judgments are made. The results of all 5 studies, with a total of 570 subjects, support Rodrigues' (1995) findings and confirm Weiner's (1995) hypothesis     

Storage of verbal associations is sufficient to activate the left medial temporal lobe

Neuroimaging studies have shown that memory encoding activates the medial temporal lobe (MTL). Many believe that these activations are related to novelty but it remains unproven which is critical - novelty detection or the rich associative encoding it triggers. We examined MTL activation during verbal associative encoding using functional magnetic resonance imaging. First, associative encoding activated left posterior MTL more than single word encoding even though novelty detection was matched, indicating not only that associative encoding activates the MTL particularly strongly, but also that activation does not require novelty detection. Moreover, it remains to be convincingly shown that novelty detection alone does produce such activation. Second, repetitive associative encoding produced less MTL activation than initial associative encoding, indicating that priming of associative information reduces MTL activation. Third, re-encoding familiar associations in a well-established way had a minimal effect on both memory and MTL activation, indicating that MTL activation reflects storage of associations, not merely their initial representation.     

Computation of Conditional Probability Statistics by 8-Month-Old Infants

A recent report demonstrated that 8-month-olds can segment a continuous stream of speech syllables, containing no acoustic or prosodic cues to word boundaries, into wordlike units after only 2 min of listening experience (Saffran, Aslin, & Newport, 1996). Thus, a powerful learning mechanism capable of extracting statistical information from fluent speech is available early in development. The present study extends these results by documenting the particular type of statistical computation–transitional (conditional) probability–used by infants to solve this word-segmentation task. An artificial language corpus, consisting of a continuous stream of trisyllabic nonsense words, was presented to 8-month-olds for 3 min. A postfamiliarization test compared the infants' responses to words versus part-words (trisyllabic sequences spanning word boundaries). The corpus was constructed so that test words and part-words were matched in frequency, but differed in their transitional probabilities. Infants showed reliable discrimination of words from part-words, thereby demonstrating rapid segmentation of continuous speech into words on the basis of transitional probabilities of syllable pairs.
