Nancy Suchman and the colleagues she influenced have produced ground-breaking and attitude-challenging work in understanding how parenting and substance use come together. Dr Suchman and her colleagues make the claim that there is nothing about a substance-use disorder that precludes effective and sensitive caring for children especially with interventions that focus on the parent–child relationship. Suchman's legacy is to highlight how substance use as an illness pulls individuals away from important, caring relationships and limits their giving themselves to those relationships. Restoring the salience of caring relationships and of the individual's ability to care may be as impactful on their substance use as a strict focus on the reduction of drug use and achieving abstinence. 相似文献

Response latencies were obtained from 10 Ss in auditory signal-detection experiments. The response latencies were inversely related to certainty that a signal was (or was not) presented. The S’s decision criterion was found to have an influence on response latency, which was consistent with the hypothesis that stimuli close to the current criterion elicit longer response latencies than stimuli more distant from the criterion. Comparisons among receiver operating characteristics derived from binary decisions, from the latencies of binary decisions, and from confidence ratings show that response latencies and binary decisions together yield more information about the stimulus than does the binary decision alone. However, the increment in information gained from the measurement of response latencies is in general (though not for every S) smaller than that gained by shifting from yes-no responses to a confidence-rating procedure. 相似文献

Body size estimates of 69 children aged 5–13 years were obtained using a TV video methodology. Tasks included an adjustment procedure where children manipulated the width of their body image on a TV, and a discrete task, where they judged the accuracy of their TV image which was presented as either normal or distorted, that is, too wide or too thin. On the continuous task, judgments were more accurate on ascending trials where children had to increase the width of the image. On the discrete task, a signal detection analysis revealed older children were better in detecting size distortion in their images and that the differences were due to differences in the biological sensory system and not due to a bias to report that they were too fat or too thin. However, there were response bias differences between genders. Females were more likely to report size distortion with increasing age while males were less likely. 相似文献

The Hippocratic Oath has survived, with overriding power, the test of time. Written somewhere between 600 B.C. and 100 A.D., it addresses the intrinsic nature of medicine. Even those of us who know little of it or reject parts of it acknowledge it to be a symbol of the values of medicine. Such "canonization" is unlikely to be arbitrary; it is more likely that the oath strikes some key chord of truth. I suggest that it is its drive to the heart of medicine that makes the Hippocratic Oath inspiring today. 相似文献

Abstract— Two experiments investigated the role of spatial organisation in the discrimination and generalization of complex visual stimuli by pigeons. In Experiment 1, after pigeons had been trained to discriminate line drawings of four objects, they were tested with novel pictures in which the same component parts of the objects were spatially rearranged. The spatially scrambled pictures led to a dramatic drop in recognition accuracy, hut responding remained above chance. In Experiment 2, pigeons reached a high level of discriminative performance when required to choose among four different spatial arrangements of the same object parts. These results confirm Cerella's (1980) conclusion that pigeons discriminate the component parts of complex visual stimuli, but. unless it is assumed that the scrambling deleted or created emergent features, the results disconfirm his conclusion that spatial organization plays no role in pigeons' picture perception. 相似文献

This investigation focused on the interrelationships among students' study activities, students' self-concept of academic ability ratings, students' academic achievement, and instructional practices in 12 high school biology courses. Using a framework derived from a previous investigation, course features were classified into those that appear to (a) place demands on, (b) support, or (c) compensate for student engagement in particular study activities. Students' study activities, self-concept of academic ability ratings, and achievement were measured with experimenter-developed instruments. Results are reported for (a) characteristics of instruments and course features, (b) relationships between central factors of the investigation, and (c) multi-level relationships between course features and student variables. Results at the student level indicated that self-concept of academic ability and, to a lesser extent, students' study activities were positively associated with student achievement. Students' self-concept of academic ability ratings were also linked to students' engagement in generative, proactive study activities. At the course level the supportive practices of providing challenging homework assignments and extensive feedback on student coursework were associated with student engagement in effortful, generative, proactive study activities. The provision of extensive feedback was also associated with high student achievement. Multi-level relationships were analysed using hierarchical linear modelling (HLM) analyses. These analyses revealed, for example, that in courses in which little or no feedback is given on homework assignments, the relationship between achievement and student engagement in diligent effort management activities was enhanced. Other HLM analyses were conducted to examine the mediating role of course features on the relationship between students' self-concept of academic ability and their study activities and achievement. For example, the presence of challenging course demands was associated with an enhancement of the relationship between self-concept of academic ability and achievement whereas the presence of instructor provisions (supports and compensations) designed to reduce course demands was associated with a reduction in this relationship. 相似文献

A major critical issue in marriage and family therapy today is the professionalization of the discipline. Thus the focus on training individuals for a career in marriage and family therapy necessitates the revisitation of the debate over personal growth versus skill development. The trend toward training the person of the therapist, however, would suggest that the field is moving toward the integration of self awareness and skill in the therapeutic system. With the popularization of training the person of the therapist comes other issues, challenges, and dilemmas for the field, including the crucial issue of training gender and culturally sensitive therapists. The potential for creating dual relationships when training the person of the therapist is both a dilemma and a challenge. 相似文献
