Subjects were presented with word pairs (e.g., bed-mattress) and timed as they decided whether one word named part of the item named by the other word. Yes responses were facilitated, and no responses were impeded, by relation similarity (i.e., the similarity of the relation between the two stimulus items to the part-whole relation). Item similarity, the similarity of the two stimulus items to each other, had no effect. The results support the view that similarity effects in semantic decision tasks are due to the comparison of elements of the relation between the two stimulus words against relation elements that serve as criteria for the target relation that the subject has been asked to identify.  相似文献

Thirty pediatricians and 30 parents were interviewed on (a) how and when children develop concepts about death, (b) children's emotional responses to the thought of death, (c) the possibility of dialogue between adults and children about death, and (d) differences in healthy and seriously ill children's conceptualization of death. Pediatricians were no different than parents in their opinions. Moreover, in some cases, less educated parents and older doctors tended to hold opinions that were even farther from reality. Overall, the results suggest that children, healthy or sick, are left alone with the problem of death and are not helped either by their parents or by their doctors.  相似文献

Training in systemic therapy necessitates a structured approach to teaching systemic thinking. The Systemic Therapy Sessions Summary Form, a record-keeping method, is presented as a tool for enhancing training in systemic therapy. The purpose of this form is to provide the structure for the trainee to develop circular hypotheses, to connect reflexively the assessment and intervention components of therapy, and to maintain a sense of the evolving nature of therapy across sessions. A case example illustrates the use of this record-keeping format.  相似文献
