In this study, we describe the process of transforming neuron polarization values that meet the assumptions of ratio data into ordinal data. This is a crisp-to-fuzzy set transformation. A computerized simulation of the application of this process is discussed and nonparametric methods of analyzing fuzzy-set data are presented. 相似文献

The sentence verification technique (SVT), developed by Royer, Hastings, and Hook (1979), provides developmental and educational researchers with an alternative way of assessing text comprehension based on all of the information contained in a passage. Students must decide if test sentences have the same meaning as sentences that appeared in an original passage. The program described here automates the more laborious aspects of constructing SVT tests. The user must create a passage using a word processor. The program will prompt the user for information as needed. Finally, printable text files (SVT test and answer key) are generated. The program is written in BASIC for IBM and IBM-compatible computers. 相似文献

A controlled comparative investigation of psychological treatments for chronic sleep-onset insomnia 总被引:4,自引:1,他引:3
A sample of physician-referred chronic insomniacs was randomly allocated to either progressive relaxation, stimulus control, paradoxical intention, placebo or no treatment conditions. Treatment process and outcome were investigated in terms of mean and standard deviation (night to night variability) measures of sleep pattern and sleep quality. Only active treatments were associated with significant improvement, but the nature of treatment gains varied. In particular, stimulus control improved sleep pattern, whereas relaxation affected perception of sleep quality. All improvements were maintained at 17 month follow-up. Results are discussed with reference to previous research and guidelines are given for clinical practice. 相似文献

The purpose of this work is to explore the phenomenon of negativism and the analyst's response to it during the course of analytic work with a patient in whom negativism is a central behavioral pattern. Melville's short story, "Bartleby the Scrivener," describing in telling detail the response of a sympathetic lawyer to profound and pervasive negativism in his legal scribe, is discussed as a literary analogy to the analyst-analysand dyad. Aspects of the concept of negativism within psychoanalysis are discussed. The potential usefulness of understanding certain unexpected countertransference responses to pervasive negativism is explored, as this is a relatively neglected area of psychoanalytic technique. A case is presented describing the analysis of a patient whose character, like Bartleby's, is a mixture of profound negativism along with schizoid, obsessional, and masochistic elements. 相似文献

Pregnant adolescents who smoke present a double obstetrical risk. Not only is the adolescent mother at risk from the biological, social, educational, and economic factors associated with childbearing at a young age, she and her developing infant also risk the complications associated with maternal smoking. This paper describes a psychosocial intervention designed to reduce smoking in a group of pregnant adolescents. Five modules are presented. Each is designed to: (1) heighten awareness of the issue, (2) provide motivational messages, (3) enhance the adolescent's social skills, and (4) teach specific smoking-cessation skills. 相似文献

Microgenesis as traced by the transient paired-forms paradigm 总被引:2,自引:0,他引:2

Two successive, spatially overlapping human faces were exposed for recognition with SOAs ranging from 20 to 160 msec. The subjects effectively perceived one face, which at short SOAs mostly resembled the first stimulus and with increasing SOAs gradually shifted towards the appearance of the second, dimmer stimulus. These results replicated those from the study by Calis, et al, and extended them to the experimental conditions of controlled simultaneity of each of the two temporally separate, extremely brief stimuli and to the conditions of personally unfamiliar stimulus-subjects. In the second experiment we employed a direct measurement of the microgenetic focus in real time by using a procedure by which the subjects' judgments about the relative temporal order of the critical visual stimulus and an auditory click were recorded. Via this procedure it was shown that one of the effects of the first visual stimulus is to speed up the microgenetic process for the second stimulus which then appears subjectively earlier as compared to the single-stimulus control. 相似文献

Loneliness as part of the human condition is first explored from an experiential-philosophical perspective. A biblical survey suggests loneliness is normative to the faith experience and may portray a more realistic religiosity. Desert imagery in Scripture indicates a strong association among solitude, spiritual development, and potential dangers of spiritual deception. God's not yet-ness-itself a cause of existential loneliness—is paradoxically the way in which communion with God functions in the here and now. The creative use of solitude may enhance social, psychological, and spiritual well-being, and provide a way to theologize about personal isolation and disorientation.He is also editor of theHarding Journal of Religion and Psychiatry. 相似文献

This study assessed sex differences affecting the psychological well-being of Chinese adolescents. Various instruments were used to measure psychiatric symptoms and positive mental health. The results showed that female adolescents displayed significantly more psychiatric as well as somatic symptoms and scored lower on scales reflecting positive mental health. The findings are generally consistent with those found in the Western literature, but suggest that, in the Chinese culture, sex differences in mental health begin to appear in adolescents. 相似文献

Shavelson's hierarchical, multifaceted self-concept model (HMFM) has proven useful to educational and psychological researchers. The reliability and factorial validity of a well-known HMFM instrument - the Fleming-Courtney Self-Rating Scales (SRS) - were examined for a sample of 198 Filipino college students. Confirmatory factor analysis compared six structural models. A six-factor, oblique model that included two social factors (Social Acceptance and Social Anxiety) fit the data best, and a second-order factor analysis supported the hierarchical structure of the SRS. The men were significantly higher than the women on three self-concept scales, but the only large effect was for Physical Abilities, consistent with findings in a U.S. college sample. Results provided some support for the utility of both the SRS and HMFM for Filipinos. 相似文献
