The authors examined the role of cognitive-resource allocation in obtaining the often reported memory advantage for bizarre relative to common information by using the secondary-task method in 4 experiments. In Experiments 1 and 2, they investigated the relationship between differences in cognitive resource allocation during comprehension and in recall for common and bizarre information. In Experiments 3 and 4, they investigated the same relationship but measured cognitive-resource allocation during imaging rather than during comprehension. Although bizarre items required more time to comprehend and to image than did common items, the differences were not reliable predictors of the recall differences between item types. Furthermore, analyses of response latencies to a secondary task provided no compelling evidence in support of a cognitive-resource-allocation explanation of bizarreness effects. Implications for the development of a comprehensive model of the influence of bizarreness on memory are discussed.  相似文献

In this study, the authors examined the interplay between biomechanics and control strategies in the resolution of excess degrees of freedom at the joint level. Seven participants made aimed arm movements from 30 starting points and several starting postures to targets. Final arm postures for movements to a target exhibited substantial joint angle variation. Through regression modeling and by comparing observed final arm postures with biomechanically plausible postures, the authors identified 3 kinematic strategies: (a) Maintain deviations from the average angle at the starting point to the joint's final posture; (b) make torso rotations that are a fixed proportion of shoulder rotations; and (c) adopt a characteristic combination of 4 wrist-positioning approaches. The results demonstrated that kinematic strategies can account for substantial variance in final arm postures, if one takes into account 2 types of individual differences—those that arise inevitably from biomechanical constraints and those that reflect choices in movement strategy.  相似文献

Forty subjects took part in a one-handed catching task in which the period for which the mechanically projected tennis ball was illuminated in flight was varied systematically. Additionally, they were tested for (a) static visual acuity and (b) dynamic visual acuity, in which angular velocity was varied. As expected, both viewing period in the catching task and angular velocity in the acuity task were significant variables in performance. Correlation and principal-components analyses confirmed the findings of a previous experiment in that the correlated static visual acuity tasks were unrelated to both dynamic visual acuity (even when angular velocity was only 75°/sec) and catching performance. Further, dynamic acuity and catching were related under the majority of the combinations, and most frequently at the highest angular velocity, a fact which suggested that the dynamic element in both tasks is the common factor.  相似文献

College students were used to test the hypotheses that judgment of an achromatic Rorschach Inkblot as ‘masculine’ is a function of largeness of mass, and darkness of shading, and judgment of one as ‘feminine’ is a function of smallness of mass and lightness of shading. It was also predicted that the sex of the judge does not influence these judgments.

The standard inkblots and mass and shading control blots were used with the semantic differential and a masculine-feminine sort technique.

The results generally supported the hypotheses tested with the ‘shading hypotheses’ receiving the strongest support. The results were related, with reservation, to the “father” and “mother” hypotheses of cards IV and VII.  相似文献

To investigate gender differences in the dynaijiics of alcohol use, we gathered self-report data from male and female college students. Results of our experiment showed that dominance power motivations were correlated with negative drinking outcomes for both men and women; assertiveness power motivations were associated with negative outcomes only for women. For both sexes, a higher proportion of positive social motivations was associated with fewer negative drinking outcomes. We expect that, in addition to the more traditionally defined needs for dominance power shown to be important for drinking among men, women may use alcohol in relation to needs for assertiveness and self-expression.  相似文献

For this article, we examine gender differences in how staff members address inmate misconduct. Using in-depth interviews with forty-three correctional employees, we focus on how their various disciplinary styles create interpersonal conflict between staff members. We find that over half of interviewees are identified as “formal responders” who consistently punish inmate misconduct with formal sanctions, even if doing so creates conflict within the organization. However, female formal responders also claim that they work closely with male inmates to explain the importance of following the rules. They state that this puts them at odds with their male co-workers who misinterpret this behavior as instigating sexual relationships.  相似文献

A problem in the processing of emotions has long been thought to be strongly associated with the aetiology and maintenance of personality disorders. Previous research has demonstrated a hyposensitivity to the faces expressing fear in those high on the traits of psychopathy, while patients with BPD have been shown to be hypersensitive to expressions in general. However, many previous studies could be explained by a bias in reporting particular expressions rather than a change in sensitivity to these expressions. Using two tasks, the present study examined both the detection and the recognition of four emotional expressions (anger, happy, sad, and fear) in a community sample of males and females. Measures of self-reported psychopathy and Borderline Personality traits were administered. The results showed marked gender differences. Psychopathy was negatively related to performance in both the detection and recognition of fear, but only for males. Borderline Personality traits were positively related to overall performance in the recognitions task, but only for females. The results suggest strong differences in the role that emotional processing might play between the genders.  相似文献

This study examined the role of suppressor effects on age differences in anxious emotion. Children and adolescents (n = 1099) ages 7–18 years were assessed for separation anxiety, social anxiety, and generalized anxiety. Results of zero-order correlations indicated a significant negative association between age and separation anxiety but no association for social anxiety and generalized anxiety. However, semi-partial correlations indicated the presence of a cooperative suppressor effect such that the associations between age and social anxiety as well as age and generalized anxiety symptoms became significant and positive and the association with separation anxiety became larger in a simultaneous regression analysis of each facet with age. Similar effects occurred when controlling for hyperarousal in an ANCOVA across grade levels. Results suggest that attempts to understand developmental differences in anxious emotion in childhood and adolescence will be facilitated by parsing facets of anxious emotion and attention to potential suppressor effects.  相似文献

Abstract

This paper considers factors that make children “at risk” for postdivorce maladjustment. The risk factors include (a) demographic variables of sex, age and socioeconomic status; (b) predivorce family functioning; (c) postdivorce relationship with the ex-spouse; (d) postdivorce parentchild interaction; and (e) social support systems. Treatment programs incorporating these factors are briefly described. Recommendations are provided for the clinician and researcher.  相似文献

Opinions of parenting programs mostly have been obtained from mothers. Because mothers and fathers' interactions with children differ, gathering data from both parents regarding behavior modification and parenting programs is necessary. This project was part of a larger study and compared mothers and fathers' acceptability of Parent-Child Interaction Therapy (PCIT) and its various components. Acceptability data were obtained using the Treatment Evaluation Inventory-Short Form and a modified version of this measure assessing specific PCIT components. The sample consisted of 40 community mother-father pairs of a young male child. Findings suggest gender differences in PCIT treatment acceptability and various PCIT components.  相似文献
