Although the concept of interpersonal pursuing and distancing has been introduced and used clinically, the lack of a reliable and valid measure has deterred its more formal investigation and relevance to personality theory. The Pursuing-Distancing (P-D) Scale, a 92-item measure of the behavioral expression of these characteristics, was developed. Evidence for internal consistency as well as internal support of construct validity is presented and discussed. An 80-item revised scale is available from the authors and is currently being evaluated in a variety of external validation settings.  相似文献

This was a study of the differences among individuals on their performance on oral and written versions of the Washington University Sentence Completion Test of ego development. The study included 192 subjects from three age groups: College age, community residents, and retired people. No oral versus written differences were found in scores. Gender was the only factor to exhibit a consistently significant effect on Sentence Completion Test score differences.  相似文献

Two studies were conducted which created and tested a scale to measure self-righteousness. Self-righteousness was defined as the conviction that one's behaviors or beliefs are correct, especially in contrast to alternate behaviors or beliefs. In the first study, a 4-item scale to measure general self-righteousness was derived which demonstrated adequate levels of internal consistency and was related to dogmatism and ambiguity intolerance. In the second study, the items were worded to be specific to running a race. This study succeeded in demonstrating that the scale possessed predictive validity. This study also demonstrated the usefulness of rewording the general items to make them specific about the content of self-righteousness.  相似文献

Male subjects were placed into one of three intoxication conditions (no ethanol, low dose, high dose) and were exposed to humorous segments from television programs. During manifest intoxication or the corresponding period in the no-intoxication control condition, they were exposed, in a balanced order, to a segment containing blunt (i.e., unsophisticated, raw) humor and to a segment containing subtle (i.e., sophisticated, refined) humor. Subjects' facial reactions to the humorous stimuli were unobtrusively recorded and later analyzed by judges who were naive about the experimental conditions. Subjects also rated the funniness of the segments. The perceived funniness of blunt humor was found to increase with ethanol intoxication. For subtle humor, in contrast, perceived funniness was found to decrease with intoxication. This divergent interaction of reported humor appreciation was less apparent in the analysis of facial expressiveness. Although correlations between ratings and aspects of facial expression were generally positive, clearly corroborative support for the humor appraisals was found only in the frequency of smiles in response to subtle humor.  相似文献

A social dilemma (Dawes, 1980) may be defined as a situation in which a collection of individuals is faced with a conflict between maximizing selfish interests and maximizing collective interests. The dilemma is based on the fact that if all choose to maximize selfish interests, all are worse off than if all choose to maximize collective interests. In a decomposed social dilemma (Pruitt, 1967), the outcomes are divided into two components: one component is based on one's own choice and the second component is based on the choices made by the others. Using 3-person decomposed games, two types of incentives were contrasted: a positive incentive (bonus) for cooperative choices and a negative incentive (penalty) for noncooperative choices. Two experiments were conducted using male college students. The results of both experiments showed that the positive incentive evoked a higher level of cooperation than the negative incentive. The results are discussed in terms of nonadditive utility components, Pruitt's motivational interpretation, and Kelley and Thibaut's (1978) theory of interdependence.  相似文献

Administered the Indian adaptation of the Rosenzweig P-F Study to 144 Scheduled Caste (SC) adolescent and 158 young adult male Indians. The results show that SC adolescents scored significantly higher on ego-defensive (ED) and extragressive (EA) and lower on need-persistive (NP), introgressive (IA) and imgressive (MA) reactions as compared to the Non-Scheduled caste (Non-SC) adolescents while there was no significant difference on any reaction among SC and Non-SC young adults. SC adolescents scored higher on NP and lower on obstacle-dominance (OD) reaction as compared to the SC young adults. Non-SC young adults were higher on EA, ED, and OD and lower on IA and NP as compared to those of adolescents. The pattern of reactions was ED-EA-NP-IA-MA-OD among adolescents and ED-EA-IA-NP-MA-OD among young adults of both the castes.  相似文献
