The personality of man is a biologic system structured on the individual’s genetic and anatomic-physiologic potentials for species-specific adaptations. The system also projects him into a social and physical environment. His relationship with this environment is as integral to his being as the unity of his organ parts are to the function of his body. His personality is the end product of all the processes inherent in this biosocial interaction. It is the final statement of his biologic presence on this planet. 相似文献

The basic models of signal detection theory involve the parametric measure,d, generally interpreted as a detectability index. Given two observers, one might wish to know whether their detectability indices are equal or unequal. Gourevitch and Galanter (1967) proposed a large sample statistical test that could be used to test the hypothesis of equald values. In this paper, their large two sample test is extended to aK-sample detection test. If the null hypothesisd
1=d
2=...=d
K
is rejected, one can employ the post hoc confidence interval procedure described in this paper to locate possible statistically significant sources of variance and differences. In addition, it is shown how one can use the Gourevitch and Galanter statistics to testd=0 for a single individual.This paper was written while the author was associated with the Institute of Human Learning at the University of California at Berkeley. 相似文献

The peripheral pathway transmitting the unconditioned stimulus information is described in a vertebrate model system for studying learning-visually conditioned heart rate change in the pigeon. In this system footshock serves as the unconditioned stimulus, and it is shown that the effective stimulation field of this stimulus, defined with respect to the unconditioned cardioacceleratory response, includes cutaneous dermatomes 21-25 (L1-Sl). The stimulus information is then transmitted by Group III and IV fibers in portions of the femoral and sciatic nerves which enter the spinal cord over segments 21-25. Further, it is shown that interrupting this pathway by section of dorsal roots 21-25 precludes establishing conditioned heart rate change with footshock as the unconditioned stimulus. 相似文献

Three procedures were assessed to determine their effectiveness in reducing anger. The procedures were: desensitization, desensitization with cognitive relaxation, and desensitization with the absence of relaxation training. Anger was aroused by exposing white males, selected for their reports of anger toward blacks, to black racial stimuli. The desensitization group reported reductions in anxiety and disgust relative to a no-treatment control group. Therapist ratings indicated reductions in anger for Ss in both the desensitization and desensitization with cognitive relaxation groups. In addition the latter group reported reductions in anger concurrently with increases in diastolic and systolic blood pressure. Post-hoc analyses indicated that Ss for whom desensitization was most effective reported less anger after the pretreatment anger arousal procedure, greater depth of relaxation during treatment, and were liked more by their therapists. These Ss also reported a greater reduction in ethnocentrism and a trend toward lower overt hostility following treatment. 相似文献

In previous investigations (Jacobson, Berger, Bergman, Millham and Greeson, 1971; Jacobson and Greeson, 1972), it was reported that as a result of the use of a behavior modification program, preschool children from poverty backgrounds demonstrated rapid conceptual acquisition. In addition, the Ss increased from the dull-normal to the normal range of intellectual functioning within approximately 20 hr of program participation. Since the increases in IQ found were most pronounced for children of lowest IQ (IQs = 46–83), the investigators hypothesized that the program would prove to be useful with Ss of greater cognitive and behavioral deficits than the initial population investigated.The present study reports the use of a variant of the conceptual acquisition program with an institutionalized, profoundly retarded microcephalic teenager with chronic brain syndrome and cerebral palsy. Prior to the study the boy demonstrated neither language nor an ability to comprehend and follow verbal directions. 相似文献

This study was designed to test the effectiveness of a short bladder training procedure to increase bladder capacity and to improve enuresis. Eighteen enuretic children, aged 5–13 years, were randomly assigned to either an experimental or control group. Pre- and post-treatment measures of bladder capacity and frequency of bedwetting were obtained from subjects in both groups. The experimental group received 35 days of bladder training administered at first by the experimenter and then by the parents. The training consisted of required drinking, practice in holding and rewards for retaining progressively larger volumes of fluid before voiding. The control group received no training during the duration of the experiment. The results showed that the mean bladder capacity of the experimental subjects increased significantly with bladder training compared to controls. However, the frequency of bedwetting of the experimental subjects did not decrease significantly with training. Consequently, the efficacy of a bladder training procedure in the treatment of enuresis is questioned 相似文献

Pigeons were exposed to a signal paired with either blackout or blackout plus shock and to another signal paired with food superimposed on a baseline of concurrent variable-interval reinforcement of pecks on two keys. The signals were changes of color of one of the two keys. The rate of pecking both keys during the signal paired with blackout or blackout plus shock was lower than the baseline rate of pecking (a conditioned emotional response), but the decrease in pecking was greater on the signal key. When the intensity of shock was increased, the rate of pecking did not decrease further on the signal key but did decrease on the other key. Rate of pecking during the signal paired with food increased sharply on the signal key (an autoshaping effect) and decreased sharply on the other key. These results support a view that there are two effects of the interaction between classical and instrumental conditioning, a stimulus-directed effect and a generalemotional effect. 相似文献
