Four experiments examined the conceptual organization of narrative passages and the extent to which these representations were explanatory in a variety of experimental tasks. The conceptual representation of a passage consisted of a graph of labeled nodes and labeled, directed arcs which were adopted from the Conceptual Dependency Theory. These representations included both explicitly stated information and inferences which had been empirically extracted by a question-answering procedure. Symbolic procedures for answering how- and why-questions were also delineated. The conceptual representations and the symbolic procedures that operate on these representations together accounted for 91% of the answers generated from question-answering protocols in Experiment 1, and also the rated quality of specific answers to specific questions in Experiment 2. Experiments 3 and 4 supported the hypothesis that structural properties of the representations can predict recall of explicitly stated nodes and verification ratings of inference nodes. The results provide encouraging support for the proposed graphic representations and also for the use of question-answering protocols in uncovering prose inferences. 相似文献

A system for monitoring blood pressure or other physiological variables in the unanesthetized and chronically instrumented dog is described. An indwelling catheter attaches to a pressure transducer affixed to the underside of a leather shield, which snaps onto a custom-fitted leather vest worn by the dog. The transducer cable ascends vertically through a hollow, flexible, stainless steel tether, which is attached at the lower end to the leather shield and at the upper end to a fluid and electrical swivel. The swivel is attached to an overhead counterbalanced boom assembly, which moves in concert with the dog, maintaining a constant minimal tension on the tether. The boom assembly is attached to a wall plate via a universal joint approximately 7 ft above floor level. Dogs can be maintained comfortably in this system 24 h/day over periods of months, with freedom of posture and movement, including rotational behavior. The system is economical to construct and provides versatile stimulation and record-ing capability and reliable long-term performance. 相似文献

The purpose of this study was to illustrate the use of time-series analysis with long-term cardiovascular responding. Analyses of two successive 1000-minute mean blood pressure and heart-rate series in five chronically instrumented dogs showed that the autocorrelation function of the original series appeared highly nonstationary and that differencing the data produced a simple autocorrelation pattern which could be successfully modeled with stepwise autoregression. Evidence for reliable individual differences as well as change over sessions is presented and discussed. 相似文献

This study of kindergarten-aged hyperactive children evaluated the effects of three modes of treatment in relation to an untreated control group. The treatments were administered over a 3-month period and included cognitive behavior modification, methylphenidate, and the two treatments combined. A follow-up assessment was done approximately 1 year later at the end of the first grade. Analyses of psychological, rating scale observational, and interview data showed that hyperactive children became less symptomatic over time;the data did not provide evidence indicating that any of the treatments studied was more effective than any other or than no treatment at all.This research was supported by grants from the Ontario Mental Health Foundation (Grant No. 701-76/78) and The Hospital for Sick Children Foundation (Grant No. 77-22). The authors wish to thank Mr. Syl Sauro, of the Etobicoke Board of Education, and Mrs. M. Stijovic, of the Etobicoke Community Health Department, for their cooperation. 相似文献

The present study investigated the effect of attitudes toward women, physical attractiveness, and competence on impression formation of women. Male and female undergraduates read a competent or incompetent essay allegedly written by a physically attractive or unattractive female and responded to questions about the essay and its writer. Subjects were classified as traditionals, moderates, or liberals on the basis of their scores on the Attitudes Toward Women Scale. Female subjects' impressions were affected by the competence of the stimulus person and by their sex-role attitudes, but were not influenced by the physical attractiveness of the writer. Males, however, were influenced by all three variables. Evidence was found for a reversal of the physical attractiveness stereotype for liberal males with reference to incompetent women. The implications of these findings for physical attractiveness research are discussed.The authors wish to express their appreciation to Walter Stephan, Judith Langlois, Janet Spence, and Richard Archer for their helpful comments on an earlier draft of this article. Thanks are also due to Richard Roberson for assistance in data collection. 相似文献

We advocate the use of a family systems approach to premarital pastoral work, involving exploration of the families of origin of the intended spouses. Family systems theory argues that a marriage is like a merger of two corporations, each having its own stockholders; thus, adequate preparation for marriage involves coming to terms with the realities of one's family of origin and that of one's intended spouse. Exploratory techniques include genograms, house tours, family photo albums, and discussions of the rules and rituals in the respective families. Leaving father and mother is the central prerequisite to marriage.Dr. Mitchell is Professor of Pastoral Care and Theology, Eden Theological Seminary, 475 E.

This paper reflects the working through of a group's fantasy that the deceased group leader wished the group to continue. As in any defense, the fantasy protected members from the pain of the finality of the leader's death. This article reveals the subjective experience concerning the effect of the leader's death on the group and members' intrapsychic struggle to separate and individuate from the deceased leader, while attending to and striving toward the group's continuation. The group's painful and growing individuation enabled the group to follow its own tasks without the spector of the deceased leader. 相似文献
