Summary Three experiments are reported to test a claim by previous subjects that lack of motivation for performing well in memory experiments yielded less than optimal performance. In each experiment the subjects of one group were informed of monetary incentives prior to study; in a second group they were informed of these incentives after study but prior to the test; no mention of incentives was made to the subjects of a third group. Recall and recognition procedures were used to assess memory performance. The data of all three experiments demonstrated no differences between the three groups with respect to performance. The claim that subjects in regular memory experiments would typically perform less than optimally is thus rejected. Subjective reports, however, revealed that incentives had affected the amount of effort put into the memory tasks. This dissociation between performance data and subjective reports is discussed in relation to the concept of motivation. 相似文献

In this paper, we present a BASIC program for Apple II series computers that allows the user to obtain perspective drawings of two-dimensional functions of known analytical expression. Also, we outline a procedure for obtaining perspective representations of two-dimensional arrays of data using the same program. The program should run on any computer with graphics mode with only slight modifications in the graphics commands. 相似文献

The psychotherapeutic life-work of psychiatrist Arthur Kronfeld has almost fallen into oblivion. Against the background of the 100th anniversary of his birth the author traces Kronfeld's psychotherapeutic career, pointing out his activity at the Berliner "Institute of Sexual Research" under Magnus Hirschfeld, and his psychotherapeutic concept--the psychagogic guidance of the patient--and its connection with the individual psychology of Alfred Adler. Kronfeld translated his theoretical positions into activities directed towards socialization and the teachability of psychotherapy which are still worthy of note by those engaged in the field. 相似文献

Cognitive, motivational, social, and environmental influences on children's food choices 总被引:2,自引:0,他引:2
This study tested the applicability of a cognitive-motivational model of health behavior to children's food choices. A sample of 107 elementary schoolchildren provided ratings of 15 foods in terms of possible choice criteria (e.g., how tasty or healthful specific foods were) and social or environmental influences (e.g., whether foods were eaten by friends or were easy to get). Several measures of food consumption were taken, and cognitive-developmental level was assessed. Within-person correlations were calculated between food choices and each choice criterion and social/environmental factor. These "correlational indices" of influences on food choice subsequently were used to identify five distinct subgroups in the sample. Children at the operational level of cognitive development tended to be in one of three groups characterized by health orientation in food choice, taste orientation, or multiple-motive orientation. Dietary quality was poorest in the taste-oriented group. Children at the preoperational level tended to have one of two undifferentiated patterns of values across the correlational indices. Results provide evidence of: the viability of cognitive-motivational models to explain children's food choices, the promise of within-person research methodology, and the potential for enhanced health behavior-change programs by use of population segmentation and tailored interventions. 相似文献

A questionnaire was developed to measure beliefs about and experiences with violence in the family. Two groups of persons in two different states who had attended conferences on battered women participated in this research. Of the 177 subjects (84% women, 16% men), none of the men had been battered, yet over one-third of the women had been; more older women reported having been adult battering victims than did younger women; the women had less formal education than the men; the women in the lower educational groups were more likely to have been battered and to report fear of becoming victims; and the social service workers reported little fear of battering. 相似文献

A general structural equation model with dichotomous,ordered categorical,and continuous latent variable indicators 总被引:21,自引:0,他引:21
Bengt Muthén 《Psychometrika》1984,49(1):115-132
A structural equation model is proposed with a generalized measurement part, allowing for dichotomous and ordered categorical variables (indicators) in addition to continuous ones. A computationally feasible three-stage estimator is proposed for any combination of observed variable types. This approach provides large-sample chi-square tests of fit and standard errors of estimates for situations not previously covered. Two multiple-indicator modeling examples are given. One is a simultaneous analysis of two groups with a structural equation model underlying skewed Likert variables. The second is a longitudinal model with a structural model for multivariate probit regressions.This research was supported by Grant No. 81-IJ-CX-0015 from the National Institute of Justice, by Grant No. DA 01070 from the U.S. Public Health Service, and by Grant No. SES-8312583 from the National Science Foundation.

One of the most serious psychosocial problems worldwide is substance abuse because of its repercussions not only on the physical and psychological health of the abuser but also on their relational functioning. Among the well-established therapeutic approaches for the treatment of substance abuse is family therapy, which, in addition to influencing personal variables, promotes changes in family dynamics. The main objective of this study is to review the scientific literature published from 2010 to the present on the efficacy and effectiveness shown by family-based treatment approaches for substance use problems both in adolescent and adult samples. In addition, the effect on secondary variables such as family functioning and behavioral problems is evaluated. The empirical evidence accumulated in the last decade and reviewed in the present study indicates that the incorporation of family members in the treatment of substance abuse produces benefits by diminishing consumption and improving family functioning. Limitations of this study and of the research reviewed are discussed and directions for future research are provided. 相似文献

This article focuses on the shift in sensitivities that took place between the 1980s and 2019 toward psychological suffering in Algeria. Promoters of psychotherapy showed an increase in receptivity—via the media, public authorities, and the general population—to their practices and discourses during this period. Based on professional literature, interviews with psychologists, psychiatrists, and psychoanalysts, and newspaper articles and essays, this article considers the following aspects: the use of psychotherapy, the authority of psychoanalytic/psychopathological analyses, and the ethics of relation in politics. Taking a social and cultural history of politics approach, it traces the discontinuous politicization of psychotherapy over the course of events (namely the uprising of 1988, the civil war of the 1990s, and the 2019 popular movement) and examines the interactions between the state, popular mobilizations, and the psychotherapists. The civil war of the 1990s coincided with the normalization of “trauma” on a global scale, and procedures for the prevention of posttraumatic stress disorder were put in place in Algeria from 1997 onwards. In this process of legitimizing psychological suffering and its treatment, the promoters of psychotherapy who belonged to the less visible margins gained authority. The year-long protest movement (2019) against the regime performed the ethics of relation, focusing on human relations, reflexivity, and living together. Promoters of psychotherapy identified consistently with the political subjectivities produced within the 2019 popular movement characterized by massive pacifist marches against the regime. 相似文献
