Relations between anger expression and cardiovascular reactivity: reconciling inconsistent findings through a matching hypothesis

Previous psychophysiological research has demonstrated that both anger expression and anger suppression are related to cardiovascular responses, but in an inconsistent fashion. The present study tested the following hypotheses: (a) that the influence of anger expression style on psychophysiological responses would be limited to Ss exposed to an anger instigation, and (b) that the specific pattern of psychophysiological responses would vary as a function of whether Ss were induced to use their preferred vs. nonpreferred mode of anger expression style in response to the instigation. Seventy-eight male college undergraduates were randomly assigned to work on a task with either an annoying or a pleasant confederate and subsequently to write either a negative or a positive evaluation of the confederate. Blood pressure was measured intermittently and heart rate continuously throughout task performance and a subsequent 15-min rest period. Ss' preferred method of anger expression had been previously assessed by a self-report questionnaire. Systolic blood pressure results generally were consistent with the hypotheses. Implications of the findings for the etiology of cardiovascular diseases are discussed.     

Backward walking: a simple reversal of forward walking?

The purpose of this study was to determine whether backward walking represented a simple temporal reversal of forward walking and, hence, could be controlled by a reversed cycling of the same group of neurons. Electromyographic (EMG), joint angle, joint moment, and joint muscle power patterns were compared for forward and backward walking, in 6 subjects. The joint angle patterns with the time-base of the backward walking reversed were similar, with the exception of the ankle. The moment patterns were similar except for the knee, whereas the joint muscle powers were almost reversed-polarity images of each other. This suggests that somewhat similar muscle activation patterns could be used to produce both modes of locomotion, but the temporal cycling of muscle contraction would be reversed: Concentric muscle activity in forward walking would become eccentric activity in backward walking, and visa versa. The EMG results generally supported these findings.     

Gender and Sex-Role Influences on Children''s Self-Esteem

This study examined direct and moderating influences of gender and sex-role orientations on children's general self-esteem. Moderating influences of these variables on the prediction of self-esteem were examined with respect to two sets of competence beliefs regarding school achievement: perceived capacities and perceived strategies for doing well in school. One hundred nineteen fourth-, fifth-, and sixth-grade children were assessed using the Perceived Competence Scale for Children (Harter, 1982), the Multidimensional Measure of Children's Perceptions of Control (Connell, 1985), and the Children's Personal Attributes Questionnaire (Hall & Halberstadt, 1980). Correlational and hierarchical multiple regression analyses indicated that upper elementary schoolchildren's general self-esteem is (a) marginally related to biological gender, with boys showing a slight advantage; (b) significantly related to masculinity and androgyny; and (c) predicted more strongly by perceived capacities to do schoolwork in girls than in boys, and by perceived (lack of) strategies for academic success in nontraditionally sex-typed children than in traditionally sex-typed children. Of the two nontraditionally sex-typed groups, androgynous children were found to have more positive school competence beliefs than were undifferentiated children.     

Autobiographical memory in a case of multiple personality disorder

Previous research on multiple personality disorder (MPD) has been concerned with between-personalities amnesia, and little attention has been paid to within-personality memory function. This study examined the autobiographical memory of a multiple personality patient, I.C., with cueing procedures that have proven useful in previous studies of normal and abnormal memory. Results indicated that I.C. was able to retrieve autobiographical episodes from the recent past, although her performance differed in several respects from that of matched controls. The study also revealed a striking deficit in I.C.'s autobiographical memory for childhood: She was unable to recall a single episode from prior to the age of 10 in response to various retrieval cues, whereas control subjects had no difficulty recalling numerous childhood episodes. This phenomenon of extended childhood amnesia has not been reported previously in studies of MPD.     

The effects of depression on structural aspects of the recall of prose

Investigated depressed patients' memory for stories. This indicated that although normal Ss showed particularly good recall for units central to the structure of the story, this did not hold for depressed Ss. In contrast, effects of centrality were comparable in high- and low-IQ Ss and effects of imageability of story units were comparable in both depressed and normal Ss. These results are consistent with the hypothesis that depressed patients do not use structure to organize stories when encoding them. A failure to identify central aspects of material and selectively recall them is likely to be a handicap to everyday functioning.     

Metamemory, memory performance, and causal attributions in gifted and average children

Fifth and seventh graders who had been teacher-selected as high- or average-achieving were tested on the Kognitiver F?higkeits Test, a standardized test of intellectual abilities for German children. Children who met preestablished criteria as gifted or average were then tested on measures of metacognitive knowledge, attributional beliefs, and performance on a sort recall task. Results indicated ability-related differences in metamemory and sort recall performances. Responses to the attributional questionnaires also varied systematically according to ability: gifted children were more likely to attribute their academic successes to high ability than were average children, who showed a stronger belief in the importance of effort in determining task outcomes. Causal modeling analyses illustrated the strength of metacognitive knowledge as a performance predictor on the memory task, especially for average children. Results are discussed in terms of the value of metacognitive theory in understanding individual performance differences.     

Comparing Idiothetic, Ipsative, and Normative Indices of Consistency

ABSTRACT Lamiell's (1981) “idiothetic” index has been praised for raising significant conceptual and methodological issues, but Paunonen and Jackson (1986a) indicated that it might not provide any unique information The current study demonstrates that the unique value of the idiothetic index relative to the ipsative, normative, and normative-ipsative indices is dependent in part upon what information is collected and how it is analyzed Subjects completed inventories on three occasions that assessed seven dispositional variables Interindividual analyses indicated a high correlation between the idiothetic method and two of the other models, whereas intra-individual analyses indicated a much lower degree of correlation Intra-individual analyses indicated that the idiothetic method produced higher temporal stability coefficients The idiothetic index provides information not contained in a normative index and it may be more useful to personality researchers for the assessment of temporal stability and for the assessment of traits with extreme base rates     

Effects of Salience of Consciousness-Raising Information on Perceptions of Acquaintance versus Stranger Rape

In the present study the effects of salience of consciousness-raising information on the perception of acquaintance vs. stranger rape were focused on. One half of the subjects were exposed to information which emphasized the inappropriateness of sexual inequality (salient condition), while the other half were exposed to no such information (nonsalient condition). Subsequently, subjects read a passage which depicted an acquaintance rape or a stranger rape. The results indicated that those subjects in the salient condition perceived the victim more favorable and reported a lesser likelihood to commit rape (male subjects) than those in the nonsalient condition. Additionally, those in the stranger rape condition perceived the victim more favorably and reported a lesser likelihood of committing rape (male subjects) than those in the acquaintance rape condition. Finally, there was a significant interaction between salience and type of rape. To amplify, when subjects read the stranger rape passage, perceptions did not vary as a function of salience. On the other hand, when subjects read the acquaintance rape passage, those in the salient condition perceived the victim more favoraby and reported a lesser likelihood of committing rape than those in the nonsalient condition.
