One consistent finding in research using the memory search task developed by Sternberg (1966) is that negative set size has no effect on search reaction time, even when the negative set contains fewer items than the positive set. Such inefficient behavior appears to result from an intense positive focus generated by standard memory search task instructions. The present research was designed to explore the conditions under which a subject will switch focus to a smaller negative set. Two experiments were carried out using standard Sternberg instructions. The first experiment examined the effects of making the contents of the negative set explicit. The result was a shift to negative focus when the negative set was much smaller than the positive set. In the second experiment the size of the positive set was increased systematically to induce a shift to negative focus. The second experiment also examined the relationship between focus shift and measures of intelligence (Raven Progressive Matrices) and information storage capacity (digit span). The results are evidence that negative set size can affect reaction time in the memory search task, and that individual differences in ability to shift focus are related to intelligence.  相似文献

A sample of 112 administrators provided self-report data used to test two hypotheses derived from Korman's consistency model of work behavior. As predicted, those with high self-esteem experienced significantly greater need gratification than did those with low self-esteem, and self-esteem also significantly positively moderated the relationship between n gratification and work satisfaction. Need gratification was assessed for only those needs that were most salient for each person, thus eliminating a rival interpretation of the findings derived from the self-enhancement model of self-esteem. The moderating effect of self-esteem on the n gratification-work satisfaction relationship was limited to those experiencing low levels of n gratification, indicating a possible “boundary condition” of consistency theory. A problem with the use of moderator variables in behavioral science was also discussed.  相似文献

Multifactorial assessment of bulimia nervosa   总被引:1,自引:0,他引:1  
We investigated a multifactorial approach to the assessment of bulimia nervosa by means of hierarchical factor analysis. Two hundred forty-five bulimia nervosa patients and 68 patients with either anorexia nervosa or eating disorders not otherwise specified were administered a self-report battery that was organized into 21 dimensions relevant to eating disorder patients. When dimensions from this battery were subjected to hierarchical factor analysis, support for bulimia nervosa as a unique diagnostic category was obtained. However, the emergence of 3 secondary factors and 6 primary factors suggests that bulimia nervosa can also be described more complexly. The emergence of a multifactorial model of bulimia nervosa that incorporates several existing undimensional models suggests the potential for both divergent and complicated clinical presentation in bulimia nervosa patients.  相似文献

Previous research suggests that pet owners are psychologically different than non-owners in terms of self-esteem and other personality characteristics. In this study, 82 pet owners and 48 non-owners were tested on self-esteem, extraversion, neuroticism, and social self-esteem. Special emphasis was placed on highly attached pet owners compared with non-owners. Level of attachment was determined by scores from the CENSHARE pet attachment survey. No significant differences were found between the groups using analysis of variance and multivariate analysis of variance statistical procedures. It was concluded that pet owners and non-owners may not be different in terms of personality but may have become victims of stereotyping by both the general population and scientific researchers. Discussion was given to related significant findings and recommendations for further research.  相似文献

Goren, Sarty, and Wu (1975) claimed that newborn infants will follow a slowly moving schematic face stimulus with their head and eyes further than they will follow scrambled faces or blank stimuli. Despite the far-reaching theoretical importance of this finding, it has remained controversial and been largely ignored. In Experiment 1 we replicate the basic findings of the study. In Experiment 2 we attempt a second replication in a different maternity hospital, and extend the original findings with evidence suggesting that both the particular configuration of features, and some aspects of the features themselves, are important for preferential tracking in the first hour of life. In Experiment 3 we use a different technique to trace the preferential tracking of faces over the first five months of life. The preferential tracking of faces declines during the second month. The possible causes and consequences of this observation are discussed.  相似文献

The effect of prevocational contact on postentry behavior was studied using a sample of staff nurses. The results indicated that those nurses who had prevocational contact with the nursing occupation had different conceptions of the nursing role and more positive work attitudes than those who did not have prevocational contact with the profession. The groups. however, did not differ with respect to turnover.  相似文献

We evaluated the initial effectiveness, maintenance, and transferability of the results of functional communication training as an intervention for the challenging behaviors exhibited by 3 students. Assessment indicated that escape from academic demands was involved in the maintenance of the challenging behaviors. Social attention was also implicated as controlling the behavior of 1 student. The intervention involved teaching alternative assistance-seeking and attention-getting phrases to the students in an effort to replace challenging behavior with these verbal equivalents. Multiple baseline data collected across the 3 students indicated that not only did the intervention substantially reduce challenging behavior but also that these results transferred across new tasks, environments, and teachers, and were generally maintained from 18 to 24 months following the introduction of functional communication training. These results are discussed in light of recent efforts to develop effective interventions for severe challenging behavior and to understand the processes underlying transfer and maintenance of intervention effects.  相似文献

Although loss of perceived control has been implicated in the development of eating disorders, previous research has not directly tested the relationship between perceived control and food consumption. This study investigated the hypothesis that individuals with anorexic tendencies react to low perceived control by restricting food intake as a means of regaining a sense of control. Forty female undergraduates who scored either low or high on the Drive for Thinness Scale (Garner & Olmsted, 1984) were led to believe they would be participating in two separate studies. Perceived control was experimentally manipulated such that half of the subjects experienced low control and half experienced high control over a social situation. Under the guise of a second experiment, subjects tasted breakfast cereals and completed measures relevant to eating and body image. Results showed that subjects who were high in drive for thinness (DT) who experienced low control ate less sweetened cereal and planned to eat less at dinner than high DT subjects who experienced high control. Low DT subjects were unaffected by the control manipulation. The results are discussed in terms of displaced reactance.  相似文献

Naming the ink color of an incongruent color word (e.g., RED printed in green) usually takes longer than naming the ink color of a color bar. However, when the ink matches the word (e.g., RED printed in red), naming tends to be faster. These phenomena are known as the STroop interference effect and the Stroop congruency effect, respectively. Although the interference effect has been robust and reliable across studies, the congruency effect tends to be elusive. It was hypothesized that this variation in outcomes might be related to subjects' response strategy. The experiment conducted to test this hypothesis induced either a speed or an accuracy strategy in two separate groups of subjects. Significant interference effects were found for both groups and the magnitudes did not differ. At the same time, the congruency effect was observed in the speed group but not in the accuracy group. These results suggest that researchers who wish to observe and study the Stroop congruency and interference effects should place special emphasis on speed. Implications of the study for a model of the Stroop effect are also discussed.  相似文献

A 3-mo. follow-up was made of 64 male veterans who were discharged from a 21-day Alcohol Detoxification Treatment Program at the Veterans Affairs Medical Center at Lyons, NJ. Scores on the Rotter I-E and Alcohol Responsibility Scales were significantly correlated with tendencies toward a more external direction among the 13% who relapsed, significant on the I-E scale and nonsignificant on the Alcohol Responsibility Scale. When tests were compared as possible predictor variables of alcoholic relapse, the difference in favor of the I-E scale was statistically nonsignificant.  相似文献
