In this study, we examined the performance appraisal process from a developmental perspective. Components of cognitive structure, measured in terms of differentiation and hierarchic integration, were obtained from 45 American students representing three different academic levels at three times during a 15-week semester. These students' performance evaluations (ratings) of their psychology instructors were collected during the first and final sessions. The results indicated that although both differentiation and hierarchic integration seemed to change systematically, even over a short period of time, there was no corresponding change in the halo inherent in the raters' ratings. We present possible explanations for the failure of developmental changes in cognitive structure to be reflected in the halo inherent in the performance ratings, as would be predicted by Schneier's (1977) cognitive compatibility hypothesis. Increased emphasis on developmental aspects of the performance appraisal process is recommended. 相似文献

Factors influencing the tendency to be aggressive were investigated in male house mice using a series of paired encounters. Body size, body lenght, body temperature, age, and anogenital distance were measured on all males. Paired encounters were conducted using a standard mouse cage as an arena. Across 64 males involved in 224 encounters, the tendency to be dominant and win encounters was significantly correlated only with anogenital distance (r = 0.383). These findings suggest that there are significant behavioral effects in male mice that could parallel the intrauterine position and related prental hormone effects that have been elucidated in female house mice and other rodents. © 1995 Wiley-Liss, Inc. 相似文献

Microcomputers can serve many functions in undergraduate education, including control of laboratory experiments, presentation of classroom demonstrations, generation of handouts, and monitoring student performance. Panel members of a symposium presented several general guidelines for the use of microcomputers, and specific guidelines for selecting and purchasing equipment and for daily operation of a microcomputer facility. 相似文献

Microcomputers may be used to simulate traditional equipment in the psychology laboratory, such as tachistoscopes, memory drums, and reaction timers. With the diminishing price of microcomputers, such simulation is especially attractive, since it is considerably less expensive than the original special-purpose equipment, and also allows greater versatility. The undergraduate laboratory described here requires only inexpensive microcomputers, simple experimental control programs, and little or no additional peripheral equipment. 相似文献

The responding of pigeons was studied in a chamber with two adjacent keys that could each be lit with either a red or a green dot. Fixed-length trials were used, with pecking on positive trials reinforced by presenting food at the end of the trial. In each session the first 40 trials were one-key trials with one key lit on each trial, either red or green, and the next four trials were choice trials with both keys lit, one red and the other green. When blocks of sessions were presented in which all one-key trials were positive trials of a single color, choice responding gradually shifted to the color presented most recently during one-key trials. When all one-key trials were nonreinforced trials of a single color, responding on choice trials shifted toward the other color. When positive one-key trials of one color were intermingled with negative one-key trials of the other color, choice responding shifted exclusively to the reinforced color. These shifts in choice responding occurred even when responding on choice trials was never reinforced, and were viewed as based on separate response tendencies for pecking red and pecking green built up during one-key trials. 相似文献

Rats received unavoidable, inescapable shock at each end of a shuttle box. A predictive signal preceded the shock when the rat was at one end of the shuttle box, while a random signal was presented when the rat was at the other end. Subjects spent significantly more than 50% of their time at the end with the predictive signal. Examination of crossover data suggested that the occurrence of crossover responses from one end to the other was influenced by the consequences of those responses, and raised the possibility that preference for predicted shock in this and previous studies was due to differential consequences that normally exist for crossover responses in each direction. 相似文献

What Good is a Feminist Identity?: Women’s Feminist Identification and Role Expectations for Intimate and Sexual Relationships 总被引:1,自引:0,他引:1
Women’s feminist identification is associated with a growing list of favorable outcomes, predicting that these correlations
will extend to egalitarian and assertive role expectations for committed and sexual partnerships, respectively. Surveying
165 undergraduate US women, nonfeminist passive acceptance was linked to low egalitarian expectations overall and across all
seven subscales of the marriage role expectation inventory. It also was related to depressed sexual assertiveness overall
and specifically in initiating sexual encounters and engaging in safe sexual practices. These negative associations were nonsignificant
or positive for women with stronger feminist identification. When endorsement of passive acceptance was controlled for, the
positive correlation between egalitarian and assertive expectations fell to nonsignificance, consistent with regarding nonfeminist
attitudes as a confounded third common factor. 相似文献

PERSISTENCE OF MEN'S MISPERCEPTIONS OF FRIENDLY CUES ACROSS A VARIETY OF INTERPERSONAL ENCOUNTERS 总被引:1,自引:0,他引:1

This study examined whether gender differences in sexually based perceptions of social interactions persist when traditional male–female power roles are reversed, when the interaction becomes progressively more sexually harassing, and when the response to the harassment is accepting or rejecting. A laboratory experiment was conducted in which 187 female and 165 male undergraduate students viewed a 5-minute videotape. Twelve versions of a scenario depicting a professor interacting with a cross-sex student were created which manipulated the sex of the powerholder, level of harassment, and response to harassment. Results indicated that men perceived the female target as behaving in a "sexier" manner regardless of her status, the level of harassment, or the victim's response. Women's sexually based perceptions of the most harassing male professor were greater than men's, however. Incorporating these gender differences in perceptions into a much-needed comprehensive model of sexual harassment (Zedeck & Cascio, 1984) appears to be warranted. 相似文献

Maternal aggression was examined in wild female mice (Mus musculus domesticus) derived from animals trapped in Alberta, Canada. Lactating females were tested for their behavior toward intruder males during the time of postpartum estrus while housed in a two-cage apparatus containing a defensible nest area. Prior to being used as intruders, sexually naive males were screened for their behavior toward a newborn pup (83% exhibited infanticide). Only infanticidal males were then housed in pairs and allowed to establish a dominance hierarchy. Dominance status was further verified by a urine marking test. The dominant and subordinate infanticidal males were then placed into a lactating female's cage and observed for 1 hr. The test was terminated immediately when a male began to attack the pups. Lactating females attacked the males in both groups, but subordinate males received more intense attacks than dominant males. Dominant males elicited significantly more fear/defense behavior than subordinate intruders. All of the dominant males and only one submissive male attacked the pups. Females were thus successful in blocking infanticide only by infanticidal subordinate males. Since females do not persist in attacking males with high fighting ability, one function of maternal aggression could be to assess the fighting, and resource holding, potential of a future mate. © 1994 Wiley-Liss, Inc. 相似文献
