We studied the correlation of one measure of imagery ability, the Visual Elaboration Scale, with two others, absorption of image and effort required to form a mental image. Significant correlations were obtained between the Visual Elaboration Scale and the other scales, with the exception of Absorption for women.  相似文献

INDIVIDUAL AND SITUATIONAL CORRELATES OF WHISTLE-BLOWING   总被引:5,自引:0,他引:5  
Although popular interest in whistle-blowing continues to increase, little is known about why some employees who observe wrongdoing report it, while others do not. In the present study, we analyze archival survey data from individuals who observed wrongdoing in any of 22 organizations. Results are generally consistent with predictions based on a model of whistle-blowing as a type of prosocial behavior. Whistle-blowing was more likely when observers of wrongdoing (1) held professional positions, (2) had more positive reactions to their work, (3) had longer service, (4) were recently recognized for good performance, (5) were male (though race was unrelated to whistle-blowing), (6) were members of larger work groups, and (7) were employed by organizations perceived by others to be responsive to complaints. Implications for research and practice are described.  相似文献

This paper gives a method for determining a sample size that will achieve a prespecified bound on confidence interval width for the interrater agreement measure,. The same results can be used when a prespecified power is desired for testing hypotheses about the value of kappa. An example from the literature is used to illustrate the methods proposed here.  相似文献

Executive career counselling is relatively new. Some of its implications are examined and a three-tiered approach by organisations is advocated. Executives are verbally fluent, and this highlights the importance of the 'opening paragraph' of words they use in counselling. Neuro-linguistic programming offers a useful set of tools to the executive career counsellor. Left-handedness, probably overlooked in most types of counselling, is briefly considered. However, counselling is not only about problems, but also offers executives a welcome chance to review their lives and careers.  相似文献

One hundred and thirty-three college students responded to percentage definitions of “good,” “minimal,” and “no” eye contact. They also judged their perceptions of a speaker with “little or no eye contact” on a semantic differential scale containing 60 polarized adjective pairs regarding personality traits. The majority of the student respondents defined an individual with “good” eye contact as looking at his/her audience/listener 90–100% of the time. This is a more stringent definition than other literature has indicated. Furthermore, speakers with little or no eye contact were judged less favorably on 70% of the items, which indicates that low eye contact adversely affects perceptions of a speaker's personality. Therefore, stutterers need to be made aware of the importance of and determinants of effective eye contact in communication. Also, the development of effective eye contact needs to be incorporated as a major goal in stuttering therapy.  相似文献

Interactions between area and numerosity   总被引:2,自引:0,他引:2  
Summary The concept of filled area, i.e. the impressionistic ensemble of parts of a stimulus field occupied by dots, is used to account for various kinds of numerosity illusions due to perceptual interaction between a number of dots and their spatial arrangement. A measure of filled area is derived from a model for the perceptual clustering of dots on the basis of relative proximity. It is shown that the quantified concept of filled area successfully predicts illusion data from earlier studies. Subsequently, a two-alternatives forced-choice numerosity experiment is reported, the data of which gave further evidence of the predictive power of the filled-area hypothesis. Our approach is discussed with respect to spatial features of dot stimuli that might be in rivalry with the filled-area factor in numerosity-estimation tasks.  相似文献

Emotional sequelae of abortion: implications for clinical practice   总被引:2,自引:0,他引:2  
For women in therapy who have had abortions, an exploration of the context and aftermath of each abortion has been suggested. This inquiry should include: characteristics of the woman herself before and at the time of the abortion, the nature of the interpersonal and cultural milieu at the time, characteristics of the medical environment and procedure, and any events subsequent to the abortion that may evoke regrets about the earlier decision.
Whether or not such an inquiry results in the identification of unresolved issues surrounding the abortion, it is likely to enhance one's general understanding of the client. Exploring a woman's decision to have an abortion can bring into relief developmental and family issues, relationship conflicts, and her aspirations for education, work, and family. A woman's approach to establishing and asserting her priorities and values in making difficult personal decisions becomes clear as does her ability to tolerate and resolve the ambivalence inherent in making difficult decisions.
In psychotherapy, it is important to understand and address those aspects of experience that women have difficulty resolving. Hence, the emphasis on categories of experience that may have a negative impact on a woman's emotional well-being after abortion. Nevertheless, the clinician should remember that even women who report negative post-abortion sequelae overwhelmingly report that they feel that the decision was the right one for them. Having ambivalent feelings to resolve does not necessarily mean that one has made a wrong choice, only that one has made an emotionally significant choice with far-reaching personal implications, in a sociocultural environment that reinforces the ambivalence inherent in such decisions.  相似文献

This study evaluated the efficacy of the Garren-Edwards Behavior Modification Program, which uses the Garren-Edwards Gastric Bubble as an adjunct to treatment. Group therapy sessions were conducted with 23 morbidly obese subjects for 6 months on a biweekly basis. Each therapy session used a five-stage problem-solving sequence designed to facilitate adaptive behavioral alternatives. In evaluating weight change, a multivariate analysis of variance was conducted along with two preplanned orthogonal comparisons. Patients lost significant amounts of weight between initial to 3-month (p<.0001) and 3- to 6-month intervals (p<0001). A similar treatment effect was noted in an additional sample of 24 morbidly obese subjects following 3 months of treatment (p<0005). The findings support the value of longer goal-oriented programs in promoting continued weight loss. Implications for treatment process and therapist interventions prompted by this new format are discussed.  相似文献

Among Drosophila melanogaster, divergently selected for geotaxis intermittently over 600 generations (28 years), about 80,000 animals have been analyzed behavior-genetically. Each major chromosome pair from two lines was isogenized on an unselected isogenic background. Measurement of their behavioral effects revealed the relative magnitudes II greater than III greater than X for the negatively geotactic (high) line and X greater than III greater than II for the positively geotactic (low) line. When reversing selection for the now phenotypically stable high and low lines and then repeatedly relaxing the reversals, a new genetic homeostasis in the low line was indicated by the return of the reversed-line average scores towards the low extreme; that is, the low line has attained a stable equilibrium for positive geotaxis, an uncharacteristic behavior and an effect not seen before 1979. This change suggests the recent evolution of a new coadaptation among genes. Although not as conclusive, a similar genetic interpretation is suggested for the high line.  相似文献
