This study tests the hypothesis that female analysts, relative to male analysts, receive a disproportionately small percentage of male referrals. Referral patterns for 170 analysts from four institutes accredited by the American Psychoanalytic Association were examined. One thousand, five hundred and ten patients referrals were studied. The findings were extremely robust and offered dramatic confirmation of our hypothesis. The major implications of the study are as follows: (1) Women analysts receive relatively few adult male referrals, making it difficult for them to gain requisite clinical experience with men. (2) Analysts and nonanalysts alike demonstrate a reluctance to refer male patients to female analysts. (3) Adult referrals, including those made by analysts, are significantly influenced by the issue of gender match between patient and analyst. (4) Analysts' behavior with regard to making referrals does not correspond to explicit clinical theory regarding how analysts make referrals--specifically, the extent to which gender influences the referral process is not adequately described by theory. We believe that these findings are of some concern from the standpoint of analytic education and that they also raise questions regarding unacknowledged aspects of how gender match between patient and analyst enters into clinical decision making.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

Darwin and others have perceived parallels between the erect bearing of proud, successful humans and the expansive demeanor of dominant animals. Various additional parallels between man and other primates in the characteristics of dominance hierarchies, the facial and postural expression of dominance, and its possible neural mediation are described. In the present study, success by human subjects in various situations was found to be reflected by erect posture. In a longitudinal study, boys who had been ranked by peers as tough, or dominant in agonistic encounters, in early grade school were observed to have erect posture in high school. Further, high school students who were judged by peers as successful by group standards tended to have erect posture. Finally, erectness of posture was related to performance on a college examination, with students' posture changing in erectness upon their receiving their grade. These results are consistent with the hypothesis that human competition for social success is based upon a biological capacity for dominance hierarchization.This research was supported in part by a Wayne State University Faculty Research Award to the first author. Portions of this report were presented at the Animal Behavior Society meeting in June 1980 at Fort Collins, Colorado.  相似文献

Vandalism is a major problem facing educators and taxpayers alike. The present investigation analyzed how vandalism costs and student disruption were related to the implementation of a training and consultation package designed to increase the reinforcing ambience of the school. A positive environment, it was posited, would displace previous events that may have set the occasion for vandalism, with cues to promote productive school performance. Eighteen elementary and junior high schools were involved over a 3-year period. Using a delayed treatment control design, treatment was delivered following either 4 or 13 months of baseline. During treatment, teams of school personnel attended training workshops in behavioral strategies for reducing vandalism and disruption by students in school. Each team also met regularly on its campus to plan and implement programs on a schoolwide basis. To demonstrate that reinforcing procedures were actually implemented and accompanied by change in student performance, these variables were periodically probed throughout the study. Project staff also provided consultation. Vandalism costs decreased significantly (p < .05) more in treatment than control schools, with an average reduction of 78.5% for all project schools. Rates of praise delivered by project teachers and other randomly selected teachers in the school increased significantly (p < .05), and rates of off-task behavior by students decreased significantly (p < .05) following treatment. The staff development model used in this study appeared to be both feasible and economical.  相似文献

This paper presents examples of mistakes committed in the process of developing an inexpensive computer laboratory for problem solving research and a larger mulituser cognitive psychology laboratory at the University of California at Santa Barbara. Major mistakes include failure to adequately plan whether the system will work, failure to check for compatibility among components, failure to develop adequate software, and failure to anticipate maintenance problems.  相似文献

In two experiments, subjects listened to a text about radar while either shadowing or not shadowing the passage. Results of Experiment 1 produced a pattern in which both groups performed at similar levels on retention of single facts, the nonshadowers excelled on transfer of the presented information to novel problem solving, and shadowers excelled on verbatim recognition of words. In Experiment 2, there was a pattern in which both groups performed at similar levels for recall of specific information, the nonshadowers excelled on recall of conceptual principles, and shadowers excelled on recall of modifying details. Implications for transfer-appropriate processing and the cognitive capacity hypothesis were examined.  相似文献

Among numerous procedures for determination of the psychophysical relation, one approach has seldom been applied. Essential in this method is to present a set of stimuli whose intensity increases in fixed time following different forms. The objective stimulus increment, which the subjects perceive as linear growth directly, represents the inverse psychophysical relation. In this paper the method was tested in the fields of click frequency and sound pressure. This procedure was named "Perception of the Form of Stimulus Increment in Time". In comparison to other psychophysical approaches, this one has several advantages. The principal ones are the following: (1) In assessing the psychophysical relation it is not necessary to try to measure the perceptual magnitude; and (2) the psychophysical relation is directly determined by its dynamic pattern. In this paper modifications to the method are reported which facilitate the subject's task and avoid some differences in subjects' individual approaches to the task. The modified procedure leads to results satisfactory independent of the influence of the factors irrelevant to the psychophysical relationship.  相似文献

In the present study, spider-phobic children (N = 22) were exposed to subliminal presentations of spiders, snakes, and mushrooms, while skin conductance responses (SCRs) were measured. In addition, pre- and post-treatment symptom severity data were obtained. As a group, spider-phobic children did not react with differential SCRs to masked phobic pictures. In addition, no convincing evidence was found to suggest that individual variation in differential SCRs to phobic stimuli is linked to pre-treatment symptom severity or therapy outcome. These findings cast doubts on the idea that phobics' phenomenal experience of their fear as irrational and uncontrollable is a result of pre-attentive physiological fear activation.  相似文献

Abstract The revised version of the Screen for Child Anxiety Related Emotional Disorders (SCARED-R) is a self-report questionnaire that intends to measure symptoms of childhood anxiety disorders as defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM; American Psychiatric Association, 1994). The current article presents three studies which examined in more detail the reliability and validity of the SCARED-R. Study 1 (N=101) demonstrated that the SCARED-R possesses satisfactory test-retest stability. Study 2 (N=71) shows that the child-parent agreement of the SCARED-R is rather low. Study 3 (N=88) provides support for the concurrent validity of the SCARED-R. More specifically, SCARED-R scores were correlated in a meaningful way with scores on the Children's Anxiety Scale, a questionnaire that also measures DSM-defined childhood anxiety symptoms.  相似文献

The influence of adaptation to taste stimuli of 1 quality on tastants with other qualities was investigated by comparing the reaction time (RT) to a test solution after adapting-solution flow with the RT to the same test solution after water flow. Adapting solutions were strong concentrations of NaCl, HCl, QHCl, and sucrose; test solutions were the same compounds but in lower concentrations. Adaptation to sucrose significantly shortened RT to NaCl and HCl, and to a lesser degree to QHCl. A similar cross-enhancement was found in sucrose when other compounds served as adapting solutions, In all other taste combinations, only a cross-adaptation effect was observed. Results are discussed in relation to some adaptation phenomena, water taste data, and magnitude-estimation data.  相似文献
