Form E of Cattell's 16PF test was administered to 515 hospitalized schizophrenics. This sample was compared to Cattell's standardization population for both raw scores and sten scores. Comparisons were made between males and females, acute patients and chronic patients, and amongst three categories of schizophrenia (paranoid, undifferentiated, schizo-affectives). The results indicate that the "schizophrenic profile," reported in previous research with Form A, did not obtain expected differentiations among schizophrenic categories. The question of the usefulness of Form E in diagnosing schizophrenia was raised. 相似文献

Studied the validity of a self-administered semi-projective packet of tests and questionnaires developed to provide quick, inexpensive information preparatory, or ancillary, to further diagnostic examinations. Brief writeups of inferences derived from the packet of tests were compared to diagnostic inferences based on from one to three psychiatric interviews, and with full examinations, which included psychiatric and social work interviews and extensive psychological testing. Generally, high comparability between the packet and both criteria were shown on questions of global diagnostic impression, character and defense, central conflicts, and basic ego functions; and significant information was often added by the packet to the data collected in diagnostic interviews. The patients filled out the packet forms conscientiously, and their written self-reports indicated that some patients could learn and otherwise benefit just from performing this task. 相似文献

The present study investigated adult behavior while interacting with a three-month-old infant under conditions in which the child was introduced as a boy, as a girl, or with no gender information given. Gender labels did not elicit simple effects, but rather interacted significantly with the sex of the subject on both toy usage and physical contact measures. There was a stronger tendency for both male and female adults to utilize sex-stereotyped toys when the child was introduced as a girl. Most of the findings, however, reflected a differential response of men and women to the absence of gender information. In this condition, male subjects employed a neutral toy most frequently and handled the child least; in contrast, females used more stereotyped toys and handled the child more. All subjects attempted to guess the gender of the child (with “boy” guesses more frequent, although the child was actually female) and all justified their guess on the basis of stereotyped behavioral or physical cues like strength or softness. 相似文献

The consistently positive relationship between initial riskiness and perceived influence obtained in past work led us to speculate that (1) the deliberative effort involved in making a choice increases with its riskiness, as a result (2) individuals who select a risky course of action will be more committed to their choice than conservative individuals, and (3) the former will be more influential in group decisions. The following support was obtained for these conjectures When individuals had to select a reaction time interval to beat, those who were risky, that is, who selected a short interval, were more confident in having chosen wisely, were less likely to feel they might change their choice given the opportunity, and took longer to make their choice than those who were conservative, that is, who selected a long interval The first two of these measures were assumed to reflect commitment to the choice, and the third was taken as a rough indication of the amount of effort involved in choosing A group decision was also made regarding the reaction time interval It tended to be riskier than that preferred by the average individual prior to the decision if the riskiest member was more committed and/or expended more effort in choosing than his partners, on the other hand, it tended to be more conservative than the average prior preference if the most conservative member was more committed and or expended more effort 相似文献

A new status index derived from sociometric analysis 总被引:21,自引:0,他引:21
Leo Katz 《Psychometrika》1953,18(1):39-43
For the purpose of evaluating status in a manner free from the deficiencies of popularity contest procedures, this paper presents a new method of computation which takes into accountwho chooses as well ashow many choose. It is necessary to introduce, in this connection, the concept of attenuation in influence transmitted through intermediaries.This work was done under the sponsorship of the Office of Naval Research. 相似文献

A novel multiple-event, multiple-item procedure was employed to identify individuals who were habitually susceptible to accepting post-event misinformation. Using this procedure, it was found that many people succumbed at least once to the effects of misinformation, given enough opportunities. Moreover, some individuals could be identified who showed a pattern of repeated susceptibility, accepting some misinformation for each of three separate events. Several individual difference measures discriminated between individuals who were habitually susceptible to false post-event information and those who were not; these include empathy, self-reported vividness of visual imagery and a memory accuracy measure. © by John Wiley & Sons, Ltd. 相似文献

Drug effects on responding maintained by stimulus-reinforcer and response-reinforcer contingencies. 下载免费PDF全文
R D Spealman J L Katz J M Witkin 《Journal of the experimental analysis of behavior》1978,30(2):187-196
The effects of pentobarbital and d-amphetamine were assessed on key pecking by pigeons under conventional single-key multiple schedules and under two-key multiple schedules in which discriminative stimuli appeared on one key (stimulus key) while pecks on a second key (constant key) produced food. Pecks on the stimulus key had no scheduled consequences. A 60-second variable-interval schedule operated in one component of each multiple schedule: either extinction or a 60-second variable-time schedule operated in the alternate component. When the alternate-component schedule was extinction, a high rate of responding was maintained in the variable-interval component of the single-key schedule; responding on both keys was maintained in the variable-interval component of the two-key schedule. Pentobarbital increased responding in the variable-interval component of the single-key schedule and increased stimulus-key, but not constant-key responding in that component of the two-key schedule. When the alternate-component schedule was changed to variable time, responding declined in the variable-interval component of the single-key schedule; stimulus-key responding was no longer maintained under the two-key schedule. Pentobarbital decreased responding in the variable-interval component of both schedules. With an exception, d-amphetamine only decreased responding in the variable-interval component of the single- and two-key schedules both when the alternate-component schedule was extinction and when it was variable time. The results suggest that the effects of pentobarbital, but not d-amphetamine, depend on the nature of the contingency (stimulus-reinforcer, response-reinforcer) that maintains responding. 相似文献

Theoretical dynamics of ethnic humor are juxtaposed with Jewish wit, showing that there is a distinct factor which operates in the Jewish humor response to oppression. Drawing from Ziv's (1986) rich anthology of research and case studies, this factor is conceptualized as creative pseudo-reality. It is hypothesized that Jewish wit features this element of self-effacing humor besides the factors which it shares with the ethnic humor of other marginal groups. The implicit ability to construct a perceived environment which is bound neither to reason nor to logic, is seen as the last line of defense for an oppressed minority whose other options have been denied. Irony and triumph, suggested as key elements in this factor, are illustrated in annotated stereotypical excerpts of Jewish wit. Throughout the analysis, the dialectic principle—maintaining the co-existence of inconsistent dynamics—is highlighted in contrast to the reductionistic either/or approach commonplace in psychological and sociological discourse. 相似文献
