Two research questions pertaining to the applicant age bias effect were addressed in this study: the effect of age-related information exposure on selection decisions and the issue of between-sample generalizability with reference to the age bias effect. Manager and student selectors made selection decisions after viewing one videotape of a simulated selection interview of either an old or a young job applicant. Before viewing the interview tape, half of each subject group was given an item of age-related information and the other half was given neutral information. The results showed that, under the neutral information condition, managers preferred hiring the young applicant for the low-status job, and students favored the old candidate for the high-status position. Under the age-related information condition, managers shifted to favoring the old candidate for the low-status job, and students preferred the young applicant for both the low- and high-status positions. Age discrimination in selection decisions and the lack of external validity of student results in selection research are then discussed.  相似文献

The incidence of secondary enuresis in 16 institutionalized conduct-disordered children was examined. In contrast to a control group of 16 noninstitutionalized conduct-disordered children, the former showed significantly more enuretic behaviour. Also, enuresis began within 6 mo. of the children's separation from their families, suggesting this problem is very likely related to the emotional trauma surrounding the change in living conditions. However, the small number of subjects limits further interpretation of the findings.  相似文献

To assess temporal variations in the perception of "phasic" heat pain stimuli a psychophysical tracking procedure was developed that enables repeated assessment of the pain threshold at short intervals. This "double-tracking" procedure produces two tracking curves simultaneously, one that approaches the pain threshold gradually from above, the other from below. The threshold for phasic heat pain was measured in 80 tracking trials with stimuli at temperatures near the pain threshold. Concurrently, the threshold for "tonic" heat pain was determined after every 20 tracking trials with a stimulus adjustment procedure. Eleven healthy subjects (age: 26.4 yr. +/- 6.0) participated in 2 sessions each. Phasic stimulation near the pain threshold did not produce any trends in either of the two threshold measures. Hence there was no long-term adaptation or sensitization. However, there were random variations (random walks) in the tracking curves, which we interpret as resulting from a stochastic relationship between stimulus and sensation. In agreement with other reports, discrimination seemed to be better at painful than at nonpainful temperatures.  相似文献

The purpose of this study was to examine the effect of massed and distributed practice upon the learning by 8 autistic children of rotary pursuit tracking at 20 rpm. The massed practice group of four completed 10 30-sec. trials with 5-sec. rests for 10 consecutive days on the Photoelectric Pursuit Rotor. The distributed practice group completed 10 30-sec. trials with 30-sec. rests for 10 consecutive days on the same device. The results of a 2 x 10 x 10 (group x practice days x trials) analysis of variance with repeated measures on the last two factors indicated that learning occurred for both groups but no differences between groups were significant. It is suggested that further investigations into the applicability of motor learning principles to special populations be conducted using larger groups.  相似文献

The purpose of this study was to determine whether test anxiety could be significantly reduced through regular practice of relaxation exercises or physical exercise. Test anxiety was assessed at pretest and posttest using the 37-item true-false Test Anxiety Questionnaire developed by Sarason. 47 undergraduate students self-selected to participate. The 9 subjects in the group who engaged in a nonmeditative relaxation exercise 3 times per week for 7 weeks showed a significant decline in test anxiety. The 16 subjects in a supervised aerobic dance class 3 times per week for 7 weeks improved their fitness and their test anxiety significantly declined. The 20 control subjects did not meet over the 7-week study ahd showed no significant change in test anxiety, fitness, or relaxation.  相似文献

Cognitive change processes in psychotherapy   总被引:1,自引:0,他引:1  
Several types of cognitive-behavioral therapy are now practiced that use different sets of theoretical concepts and propose different kinds of change mechanisms. None, however, is directly grounded in experimental research in cognitive and social psychology, and few address basic issues such as the relevance of conscious versus nonconscious cognitive processes and the validity of the self-report data on which therapy depends. Put forward in this article is a model that describes the conscious and nonconscious processing of emotional stimuli and distinguishes between knowledge that is verbally accessible and knowledge that can only be recovered by exposure to situational cues. Also proposed are three mechanisms of cognitive change that involve altering verbally accessible knowledge, the accessibility of nonconscious situational memories, and self-regulatory strategies. These mechanisms are related to the current practices of behavioral and cognitive-behavioral therapists.  相似文献
