The separate questions on an essay test or the individual judges on a rater panel may constitute congeneric parts rather than
tau-equivalent parts. Also, it may be necessary to infer the lengths of the congeneric parts from their variances and covariances,
rather than from some obvious feature of each part, such as the range of possible scores. Cronbach's alpha coefficient applied
to such part-tests data will underestimate total score reliability. Several reliability coefficients are developed for such
instruments. They may be regarded as extensions of the coefficient developed by Kristof for a three-part test. 相似文献

The component scales from which Bem's index of psychological androgyny is derived are better thought of as measures of dominance and nurturance, rather than “masculinity” and “femininity.” When the Bem scales were administered to 202 male and female college students, along with eight scales that form an interpersonal circumplex, it was once again found that stereotyped, near-stereotyped, and androgynous classifications on the Bem index generalized to sex-role stereotype classifications on other dimensions of interpersonal behavior, as well. Moreover, the Bem index was found to be based on the best available combination of orthogonal interpersonal scales for measuring sex-role stereotypy. In this recent sample of college students, the hypothesis that Bem's index of androgyny reflects the more general construct of interpersonal flexibility was confirmed for both male and female subjects. The recognition that Bem's index of androgyny is specific to the interpersonal domain should encourage others to develop androgyny indices in other domains such as temperatment, interests, and cognitive styles. 相似文献

Conclusions Except for Mowbray, the commentators approach the issue of mental health services quite differently than we do, a fact which may have contributed to some of their misconceptions. Although not stressed in our original report, our view of mental health services is eclectic and pragmatic, encompassing a wide range of psychosocial approaches. We agree with Salem that a range of options needs to be developed and maintained. The motivation for the development of both the ACT and DIC programs was to address the needs of a population neglected by existing mental health services. By contrast, the commentators' agendas converged on the promotion of nonprofessional forms of help-giving. Like the commentators, we have long advocated for consumer choice, self-help groups, and the use of natural supports. Where we part company with them is what we hypothesize would be a minimally sufficient response to over 2 million persons with SMI in the United States. For us, it is not enough to assert that self-help groups might be a partial answer. For us, the self-selection into self-help groups and drop-in centers (which all of the commentators readily acknowledge) leaves open some troubling questions from apolicy standpoint about what happens to those who do not self-select into such groups, especially because we believe that those who select themselves out are likely to include some of the most vulnerable segments of the SMI population.

The effects of positive and negative interactions on children's performance and preferences for the adults associated with each type of interaction were studied. Five children served as subjects during daily sessions in which each of three adults followed prescribed patterns of social interaction. One adult (positive) dispensed positive comments contingent upon either color-sorting or completion of arithmetic problems; a second adult (negative) mildly reprimanded the child for off-task behavior; and the third adult (extinction or nonreactive) said nothing to the child when he was present. Following each session the three adults reentered and the child chose one of them for an additional period of interaction. Three response measures (frequency, latency, and percent of time on-task) and children's adult preferences were obtained daily. The negative adult affected the most task behavior and had strongest stimulus control; the positive adult, though exerting little control over children's behavior, was the most preferred. Children's adult preferences were not specific to the task setting, but were observed across a variety of contexts. 相似文献

Rats received either partial reward (PR) or partial delay (PD) in acquisition with one, two, or three delay or nonreward trials followed by an immediately rewarded trial or one delay or nonreward trial followed by an immediately rewarded trial. These four groups were then split in half and given either continuous delay or continuous nonreward (extinction) in a “response persistence” phase. In addition, two continuously reinforced groups, one experiencing continuous delay, and the other experiencing extinction were included. The results showed that response persistence was greater when PD groups were given continuous delay rather than extinction, but the opposite was true for PR groups. The “length” (1, 2, or 3 versus 1 nonreward or delay trial) also transferred to the response persistence phase with the length 1, 2, and 3 conditions being more persistent than the 1 length conditions. The results were discussed with respect to theoretical notions of response persistence. 相似文献

Published reports provide contradictory evidence concerning the cause, nature, and course of Sydenham's chorea: Physiological, psychological, and interactional hypotheses have been advanced. Reports supporting any of these views suffer from lack of detail, objective observations, and/or longitudinal behavioral sampling. This case was studied longitudinally with numerous psychological tests. They revealed acute encephalopathy and severe personality disturbance in the acute stage, followed by rapid and lasting clearing of both symptoms. Thus, this case provided evidence consistent with virtually all published reports and with each hypothesis about Sydenham's chorea, suggesting the need for more careful longitudinal studies and a conceptual framework which can more fully embrace all the data.This study was begun while the author was at the William S. Hall Psychiatric Institute in Columbia, South Carolina.The author gratefully acknowledges the comments of Professor Arthur L. Benton. 相似文献

In Expt 1, male Betta splendens were given a choice between food and a mirror image in a T-maze. All fish consistently preferred food. In Expt 2, the choice of fish that lived in the T-maze for the duration of the experiment was compared with the choice of fish that were transferred to the T-maze for each experimental session. Fish that lived in the T-maze consistently preferred food, but fish that were transferred showed a shift in preference toward mirror image. Differential inhibition of hunger and aggression by fear is suggested as the cause of the preference shift. 相似文献

To determine whether correspondence in appearance between helper and helped will increase the rate of helping behavior, two types (Hippie and Straight) and two sexes of experimenters approached each of the four corresponding types of subjects and asked to borrow a dime for a telephone call. As predicted, a significantly greater number of persons were willing to lend money to someone who resembled them in appearance. Furthermore, as predicted, his tendency to match on the basis of appearance was stronger for male subjects than for female subjects. It was hypothesized that dress styles, like race, provide a basis for assumptions about other areas of similarity and create a greater willingness to help a similar other. 相似文献

For the past two and one-half years, the self-defeating behavior (SDB) theory has been applied to a population of veterans who had a history of problems in job training, vocational placement, and academic settings. A group-therapy structure meeting eight times during a four-week period is the basic approach of the SDB seminar. In conjunction with the SDB seminar, a variety of support people and agencies have combined efforts to develop a systems approach to helping the veterans eliminate behaviors that are self-defeating. Results from the systems approach have been excellent. 相似文献
