ABSTRACT Lamiell's (1981) “idiothetic” index has been praised for raising significant conceptual and methodological issues, but Paunonen and Jackson (1986a) indicated that it might not provide any unique information The current study demonstrates that the unique value of the idiothetic index relative to the ipsative, normative, and normative-ipsative indices is dependent in part upon what information is collected and how it is analyzed Subjects completed inventories on three occasions that assessed seven dispositional variables Interindividual analyses indicated a high correlation between the idiothetic method and two of the other models, whereas intra-individual analyses indicated a much lower degree of correlation Intra-individual analyses indicated that the idiothetic method produced higher temporal stability coefficients The idiothetic index provides information not contained in a normative index and it may be more useful to personality researchers for the assessment of temporal stability and for the assessment of traits with extreme base rates 相似文献

In the present study the effects of salience of consciousness-raising information on the perception of acquaintance vs. stranger rape were focused on. One half of the subjects were exposed to information which emphasized the inappropriateness of sexual inequality (salient condition), while the other half were exposed to no such information (nonsalient condition). Subsequently, subjects read a passage which depicted an acquaintance rape or a stranger rape. The results indicated that those subjects in the salient condition perceived the victim more favorable and reported a lesser likelihood to commit rape (male subjects) than those in the nonsalient condition. Additionally, those in the stranger rape condition perceived the victim more favorably and reported a lesser likelihood of committing rape (male subjects) than those in the acquaintance rape condition. Finally, there was a significant interaction between salience and type of rape. To amplify, when subjects read the stranger rape passage, perceptions did not vary as a function of salience. On the other hand, when subjects read the acquaintance rape passage, those in the salient condition perceived the victim more favoraby and reported a lesser likelihood of committing rape than those in the nonsalient condition. 相似文献

Issues pertaining to the accurate diagnosis of personality disorders are discussed from a scientist-practitioner perspective. An attempt is made to distinguish state (Axis I) from trait (Axis II) disorders, and personality (“normal”) from personality disorders (“abnormal”). The reliability and validity of personality disorder diagnoses are explored, and the four criteria for all personality disorder diagnoses are clarified: These criteria are: 1) presence of psychological symptomology, 2) stability over time, 3) consistency across situations, and 4) under-responsiveness to currently available treatments. Also, a distinction is made between categorical and dimensional diagnostic criteria, similar to the distinction between personality type and trait approaches. Recommendations are provided for improving the clinical and empirical work in this area, and implications for treatment are discussed. 相似文献

This study identifies the direct effects of objective job conditions on individual perceptions of job conditions. The assumptions that (1) group perceptions mediate the relationship between objective job conditions and individual perceptions of job conditions, and (2) group consensus enhances the relationship be-between group perceptions and individual perceptions were tested. Respondents were white, male, blue collar workers (N= 1240) in a tire and rubber manufacturing plant. Work groups (N= 156), consisting of four or more men on the same shift, in the same department, and who had the same supervisor, were identified. Objective job conditions included work group size, pay style, shift, and job technology. Group and individual perceptions of amount of work-load, role conflict, responsibility pressure, and intrinsic rewards were measured. The findings indicated that objective job conditions have important effects on individual perceptions of stressful and rewarding job conditions. Smaller work groups, and jobs that pay on an hourly rather than a piece-work basis, allow for some control over the pace of work, and allow for interaction among fellow workers resulted in higher levels of intrinsic rewards and lower levels of workload, role conflict, and responsibility pressures. An intriguing pattern appeared where, in perceptions involving interpersonal relations, work group influence was relatively more important than objective job conditions. When assessing task oriented aspects of work, objective job conditions were more important than group perceptions. 相似文献

The influence of perceived somatotype on stereotypes of behavior associated with body build was investigated among 160 male and 140 female Nigerian children in secondary school. In both groups, the perception of subjects' own physiques and discrepancy between their perceived and preferred physiques significantly explained the variance in the character trait scores attributed to body types. In general, the subjects attributed positive character traits to their perceived somatotypes and undesirable traits to the physiques with which they were dissatisfied. Thus, the perception of somatotype and discrepancy between perceived and preferred physique could significantly differentiate the character traits attributed to body build among male and female children. 相似文献

Summary Four experiments were conducted to examine processes in identification and selective adaptation of hues in color perception that exactly parallel processes in identification and adaptation of auditory detectors that provide information for phonemic perception. The first experiment demonstrated an effect of adaptation on identification of blue and green when a hue category center was used as the adaptor; this experiment also assessed recovery from adaptation. Adaptation to one hue was found to shift identification to favor the alternative hue, implicating a single detector underlying hue categorization. The second experiment demonstrated similar effects of adaptation between green and yellow. The third experiment compared the magnitudes of shift following adaptation with a category center, a near-boundary hue, and variously graded adaptation series. Adaptation was found to be related to the category representativeness of the adaptor(s). Results of the third experiment also provided support for the view that adaptation, rather than response bias, is responsible for shifts in the position of identification functions following extended stimulus exposure. The fourth experiment explored the neural loci of adaptation by an interocular transfer test. Hue adaptation was found to occur at both central and peripheral loci. In the four main experiments, reaction times to identify hues in unadapted and adapted states were also analyzed and compared. Subsidiary experiments assessed the effects of stimulus luminance on the magnitude of adaptation. General principles of categorical perception and its underlying bases, including the sweep, magnitude, and symmetry of adaptation, are discussed. The principal findings of these studies provide new data on hue perception which strikingly parallel findings in speech perception. 相似文献

Aggressive behavior inhibition by serotonin and quipazine injected into the amygdala in the rat 总被引:1,自引:0,他引:1
The effects on aggressive behavior, open-field activity, and pain threshold of bilateral microinjections of serotonin (20 micrograms) and quipazine (20 micrograms), the direct serotonergic receptor agonist, into the cortico-medial amygdala were investigated in Wistar rats. Both drugs significantly prolonged the attack latency in isolated killer rats (predatory aggression model), and suppressed the incidence of aggressive postures/attacks in shock-induced fighting test (affective aggression). The only difference in the open-field behavior was the lower number of central square entries in drug-treated compared to saline-injected rats. None of the substances produced any significant change in jump threshold. It is concluded that stimulation of serotonin receptors within the amygdala produces inhibition of affective and muricidal behavior in isolated rats. The effect does not seem to be dependent on changes in general activity and pain sensitivity. 相似文献

Microcomputers can serve as automated testing stations for use in psychometric assessment. There are economic advantages in conducting aptitude and intelligence testing with such stations. It is possible to improve the quality of cognitive assessment by extending the range of cognitive abilities to be assessed? Two types of extension are considered; modifying and expanding testing procedures for psychological functions that are components of conventional tests, and the extension oof testing to psychological functions not generally assessed by conventional intelligence or aptitude tests. Computerized presentations will make relatively little difference in our ways of testing verbal comprehension. Computer controlled testing could well extend the ways in which we evaluate spatial-visual reasoning and memory. The impact of testing on the evaluation of reasoning is unclear. Computer-controlled item presentation makes it possible to conceive of tests of learning and attention, neither of which are evaluated in most psychometric programs today. The psychological nature of the abilities being assessed raises problems in assessment that are not addressed by the fact oof computer-control. Some research questions are identified that ought to be explored before testing is extended into these fields. Computer-controlled evaluation could be extended to the assessment of criterion performance, either in the normal working situation or in a simulation of the workplace. While evaluation of this sort does raise social questions, it clearly presents an opportunity to obtain validation data for psychological assessment studies. 相似文献
