Zusammenfassung Die ursprünglich von John Bowlby entwickelte Bindungstheorie gewinnt zunehmend an Relevanz im Bereich der Psychotherapie(forschung). Diese übersicht beginnt mit einer Kl?rung der zentralen Begriffe und Annahmen dieser Theorie und fa?t einige Befunde zur Entwicklung und den Korrelaten von Bindung zusammen, die vornehmlich aus entwicklungspsychologischen Untersuchungen stammen. übertragen auf Erwachsene, bedürfen die Konzepte der Bindungstheorie einer Revision, die in dieser Arbeit skizziert wird. Schlie?lich werden auf dieser Basis einige heute übliche Methoden zur Erfassung von Bindungsstilen und Bindungsverhalten im Erwachsenenalter dargestellt, die bei Untersuchungen im klinischen Feld (Inhalt des 2. Teils der übersichtsarbeit) eine wichtige Rolle spielen.   相似文献

In the August 1993 issue ofJournal of Applied Psychology, Deniz Ones, Vish Viswesvaran, and Frank Schmidt published a monograph on the validity of integrity tests as revealed by meta-analysis. They concluded that integrity tests have substantial and generalizable predictive validity for criteria of both overall job performance and counterproductive behaviors on the job (e.g., disciplinary problems, absenteeism, rule breaking, violence on the job, theft, etc.). During the Fall of 1992, the authors sent a preprint of this study to David Lykken of the University of Minnesota, stimulating the exchange of letters that is reproduced here. The doubts, concerns, and feelings about integrity tests expressed by Professor Lykken are likely to be shared by others. The responses by Professors Schmidt, Ones, and Viswesvaran attempt to show that these worries are unfounded.  相似文献

A quantitative method is developed for assessing the quality of pattern information in imagery, using the magnitude of color aftereffects as an objective index. Subjects were given instructions to project imagined bar patterns of particular width and orientation onto adapting color fields, in such a manner as to simulate standard conditions for establishing the McCollough effect. Our control procedures indicate that the resulting orientation-specific complementary color aftereffects cannot be attributed to the conditioning of particular directions of eye scanning movements to color processing during adaptation, or to other possible sources of experimental bias. Furthermore, subjects who rated themselves prior to the adaptation procedure as having relatively vivid imagery showed significantly larger aftereffects than those who reported having relatively low imagery. These results not only provide an important confirmation of our earlier finding that imagination can replace physical pattern information in the formation of basic color-feature associations in the human visual system, but also demonstrate that these aftereffects can provide a practical measure of the fidelity of pattern representation in visual images.  相似文献

The variable that affect motor programming time may be studied by changing the nature of the response and measuring the subsequent changes in reaction time (RT). One notion of motor programming suggests that aiming responses with reduced target size and/or increased target amplitude require more "complex" motor programs that require longer RTs. In a series of five experiments which movement time (MT) was experimentally varied target size neither influences RT when the movement amplitude was 2 or 30 cm nor when the target sizes differed by as much as a factor of 16:1. Increasing the movement amplitude from 15 to 30 cm also had no influence on RT. Movement time, however, did affect RT, with 200-msec movements having longer RTs than 120-msec movements. Target size and movement amplitude did not appear to be factors that influence programming time or program complexity.  相似文献

This paper describes a test chamber, a food acquisition task, and a training procedure for the long-term testing of an implanted mouse in a circadian rhythm experiment. For the training phase, a special-purpose controller is provided to a single cage. For the experimental phase, behavioral, electrophysiological, and environmental measures are collected by means of a mini-computer.  相似文献

The present study compares the effects of two different socialization environments—the Israeli kibbutz and the city—on the social values held by 16-17 year-olds. A total of 352 boys and girls, 195 porn the city and 157 porn the kibbutz, filled out a specially prepared thirteen-item questionnaire on social values. The results revealed the existence of four factors underlying these values: self-oriented concerns (factor 1), other-oriented concerns (factor 2), reliance on innate spiritual capacities (factor 3), reliance on physical and productive capacities (factor 4). Significant differences on factors 1 and 3 were uncovered for the kibbutz and the city subjects, while boys and girls differed significantly on factors 2 and 4. The findings were discussed in light of the differences in educational systems between the kibbutz and the city, and in light of sex-role differences characteristic of Western society in general.  相似文献

A 2×2×2 factorial design was employed to examine the influence of instructed leadership style, sex of leader, and sex of followers on leader behavior, subordinate satisfaction, and productivity in a simple task. In general, male and female leaders were equally able and equally willing to display autocratic and democratic leadership styles if so instructed. Similarly, leader sex did not have a significant influence on subordinate satisfaction or productivity either by itself or in interaction with leadership style or follower sex.  相似文献

Task dynamics corresponding to rhythmic movements emerge from interactions among dynamical resources composed of the musculature, the link segments, and the nervous and circulatory systems. This article investigated whether perturbations of interlimb coordination might be effect over circulatory and nervous elements. Stiffness of wrist-pendulums oscillated at a common tempo and at 180 degrees relative phase was perturbed through the use of tonic activity about an ankle. Left and right stiffnesses, the common period, and the phase relation all changed. Stiffnesses increased with ankle torque in proportion to the wrist's inertial load. Despite different changes in stiffness at the two wrists, isochrony was preserved. The stability was shown to be consistent with the proportionality of changes in stiffness to the inertial loads. The phase departed from antiphase in proportion to the asymmetry of inertial loads. The size of departures decreased with increasing ankle torque. An account was developed in terms of muscular, circulatory, and nervous functions.  相似文献
