Coercion theory provided the theoretical rationale for the present study. The hypothesis was that mothers' reports of child behavior problems and mothers' reports of external locus of control would be related to abuse potential. A total of 95 mother-child pairs were screened for child abuse potential during visits to a hospital-based pediatrie clinic. Following brief interviews, mothers completed three measures: Milner's Child Abuse Potential Inventory, Levenson's Locus of Control Scales, and the Revised Behavior Problem Checklist. Perceptions of control by powerful others and by chance were related to abuse potential for mothers of both sexes. Mothers' reports of their sons' anxiety-withdrawal and conduct-disorder behavior problems were related to abuse potential. There was a significant association among lie scores, internality, and abuse potential for mothers of female children. Mothers with high abuse potential reported significantly more behavior problems in their children. The findings were discussed in relation to coercion theory.Portions of this paper were presented at the biennial meeting of the Society for Research in Child Development, Detroit, April 1983. This research was conducted by the first author in partial fulfillment of the requirements for the Ph.D. at the University of Miami under the direction of Drs. Keith G. Scott and Annette M. La Greca. The first author wishes to thank the members of the committee, Drs. Herbert C. Quay, Simon B. Miranda, Daryl Greenfield, and Julia Rosenkrans, for their many contributions. Also, special thanks to the University of Miami Child Protection Team for their continuous support and guidance, and special appreciation to the mothers and children who participated in the study.  相似文献

Subjects were timed as they made decisions about the location of an asterisk placed to the left, right, top, or bottom of disoriented shapes, and their reaction times were plotted as a function of the angular departure of the shapes from the upright. In Experiment 1, the shapes were letters, and the functions suggested that the subjects generally mentally rotated some internal representation of each letter to the upright in order to decide whether the asterisk was to the left or the right, regardless of whether the letters were vertically symmetrical (A, T, U, V), horizontally symmetrical (B, C, D, E), or asymmetrical (F, G, R, L). For decisions about top and bottom, mental rotation rarely occurred, although there was some evidence for it in the case of horizontally symmetrical letters. Experiment 2 showed that mental rotation was not involved when subjects made one response if the asterisk was to the left or right, and another if it was at the top or bottom. In Experiment 3, the shapes were relatively unfamiliar architectural symbols, and in this case mental rotation was most strongly induced by those decisions requiring mirror-image discrimination, that is, left-right decisions for vertically symmetrical shapes and top-bottom decisions for horizontally symmetrical ones. Taken overall, the results suggest that there are two task ingredients that may induce mental rotation: One is the labeling of the left and right sides of a disoriented shape, and the other is the discrimination of mirror images.  相似文献

Trends in women's labor force participation between 1967 and 1981 are noted as background to this 14-year longitudinal study of 117 women who graduated from college in 1967 and were studied in 1967, 1970, and 1981. The women represent a stratified random sample of the graduating class of 1967 from one large midwestern university. The three strata are role-innovators (women in male-dominated occupations, traditionals (women in female-dominated occupations), and moderates (women in occupations having 30 to 50% women). Samplewide changes are consistent with national trends: increased employment, increased role-innovation, greater educational achievement, and later and smaller families than expected in 1967. There was also a dramatic increase in perceived conflict between marriage and career. Within these trends, however, large parts of the sample showed strong consistency: 81% of the original role innovators and 69% of the original traditionals were still role-innovators and traditionals, respectively, in 1981. This longer term consistency overrode a great deal of temporary change in the traditional direction between 1967 and 1970, particularly for the role innovators and moderates. Much of this temporary shift was associated with early child rearing. Factors associated with increased role innovation and increased traditionality were the importance women gave to having a career, the relative priorities they placed on career vs family, their expectations of marriage-career conflict, and their expections of husband's acceptance of their career. Increased role innovation was also associated with attaining more education, not marrying, and having fewer children.  相似文献

Conclusion The SS-B appears to be a promising measure of five modes of available supportive behavior: emotional support, socializing, practical assistance, financial assistance, and advice/guidance. The measure was designed to assess supportive behavior available from family and from friends. For specific purposes the measure might be modified to tap enacted supportive behavior, as was done in Study 4, or might focus on different sources (cf. Tardy, 1985). Further evidence of the divergence of mode-specific scales would be valuable and might be demonstrated by comparing samples with mode-specific deficits, by comparing support received for different problem types (in a more sophisticated fashion than was done here), and by showing differentiated associations between modes of support and various outcome variables. The reliable and valid assessment of specific modes of supportive behavior is an important agenda item in social support research: Such a measure would allow more elaborate theories to be tested, and will undoubtedly prove essential in a complete understanding of social support processes.  相似文献

This study was addressed to the determination of the stage at which semantic analysis occurs during a STM recognition task. A list of exemplars (memory set), drawn from 13 different categories, was presented at a rate of 11/2 sec/item, followed by a category name probe. Ss then indicated whether any of the exemplars in the memory set belonged to that category. List length was varied from 5 to 7, with each memory set containing items from either two or three categories. It was found that RT was independent of list length, but did increase by 60 msec as the number of categories represented in the list increased from two to three. From this, it was concluded that activation of a superordinate category representation occurred upon presentation of each memory-set item, and that the memory scan was done on these superordinate categories.  相似文献

Work-related needs and abilities appear to be significant factors in the vocational adjustment of psychiatric patients. When vocationally oriented patients were compared to a carefully matched normal sample, the patients were found to have significantly less agreement between their work needs and their work abilities. Although no difference was found to exist between the work needs of the patients and the matched normals, the work-related abilities of the patients were distinctly lower than those of the normal population, implying that the appropriate focus of vocational rehabilitation counseling is the augmentation of patient assets. Persons most likely to have incongruity vocationally between their needs and abilities are male psychiatric patients, aged 24 to 36, who have less than a high school education.  相似文献

At an early age, children attain concepts of sex-appropriate activities, behaviors, attitudes, and goals, i.e., sex-role stereotypes. These conceptual stereotypes seem to assign a less favorable role to females. Thus it seems plausible that their acceptance (by both sexes) might be at least partly responsible for the performance differences that begin to arise in adolescence and adulthood. In view of the importance of early adolescence as a transitional period during which sex-role requirements are augmented and intellectual sex differences emerge, 105 11-year-olds and 102 14-year-olds were selected as subjects. Their spatial abilities, sex-role concepts, and sex-role preferences were assessed. Stereotyping sex roles (in general) was not associated with spatial performance; stereotyping sex roles that included information regarding subjects' views about intellectual competence was related to performance. The sex difference in spatial ability that emerged at age 14 was among subjects with own-sex preferences only; there were no sex differences among subjects who preferred to be boys.This article is based upon a doctoral dissertation presented to the Department of Psychology of Columbia University. The author would like to express her thanks to her advisers, Phillip Shaver and Deanna Kuhn; to her committee members, Robert Krauss, Norma Graham, Patrick Lee, and Wayne Proudfoot; to Carol Jacklin and Ruth Wylie for their advice and support; and to Flora Churnin, Douglas Churnin, and Carl Nash for their invaluable assistance during all phases of this study.  相似文献

Data obtained from a two-year follow-up of 10 obese women treated via behavioral methods is presented. Failure to obtain lasting results was noted, and reasons for this failure suggested. Implications of these data for investigators in the area of obesity were discussed.A review of the recent literature indicates a number of studies with encouraging results obtained via the behavioral treatment of obesity (Hall and Hall, unpublished). However, long-term follow-up data are generally lacking. This lack of long-term data is especially troublesome in the area of obesity. With regard to traditional treatment methods, such as drugs, psychotherapy, and nutritional counseling, it has generally been noted that those overweight individuals who complete a course of treatment, and who lose weight, regain the weight lost (Stunkard and McClaren-Hume, 1958) Within the literature on the behavioral treatment of obesity, only one study (Stuart, 1967) has provided weight data for as long as 1 year after initiation of treatment Stuart's data indicated a gradual loss of weight over the year. However, these data did not reflect S's ability to control weight following termination of treatment, for during the year, follow-up sessions were scheduled monthly, and thus, therapist contact was available.The present paper, in an attempt to fill the need for long-term follow-up data, presents data obtained 2 years after the termination of a behavioral treatment program. None of the Ss had been in contact with the therapist since the termination of the study 2 years earlier.  相似文献

Ninety-nine teachers participated in a survey designed to assess teacher attitudes toward and experience with a variety of strategies for dealing with conduct problem children in regular classes. Results indicated that (a) a majority of teachers favored placing conduct problem children in regular rather than special classes; (b) current sources of assistance (school psychologists, clinical psychologists, principals, parents, and other teachers) were uniformly perceived as only slightly effective in helping teachers handle problem children; and (c) of 14 alternative educational and psychological assistance delivery strategies, teachers most frequently preferred smaller classes, teacher aides, increased counseling staff, and resource classrooms.This study was funded as part of Grant No. OEG-0-71-2872 from the U.S. Office of Education. The opinions expressed in this paper are in no way intended to reflect those of the granting agency. The suggestions of Marlene Schneider, Eleanor Wilcox, Ruth Shepard, and Susan O'Leary were extremely helpful in the initial formulation of the questionnaire used in this study. The authors are further indebted to Kenneth Kaufman, Marvin R. Goldfried, Leonard Krasner, Lillian Stevens, W. E. Hedley, and R. Mullaney for allowing us to use their continuing education courses as the sources of our sample of teachers, and to the many teachers who completed the questionnaire.  相似文献
