This study investigated the effectiveness of an AIDS educator as a function of his HIV status and sexual orientation. A 2 × 2 factorial design was employed where 136 heterosexual undergraduates viewed I of 4 videotapes of an AIDS educator who introduced himself as either HIV positive or negative and either heterosexual or homosexual. The videos were identical except for the introduction. Results revealed that all videos increased knowledge about AIDS. However, students' perceptions of risk increased only when they believed the educator was HIV positive and heterosexual. Intentions to get tested for HIV increased when they perceived the educator as HIV positive but declined when they thought she was HIV negative. Results suggest the sexual orientation and HIV status of educators can impact their effectiveness. 相似文献

We examined the possible relevance of locus equations to human production and perception of stop consonants. The orderly output constraint (OOC) of Sussman, Frachter, and Cable (1995) claims that humans have evolved to produce speech such thatF2 at consonant release andF2 at vowel midpoint are linearly related for consonants so that developing perceptual systems can form representations in anF2 ons-by-F2 vowel space. The theory claims that this relationship described by locus equations can distinguish consonants, and that the linearity of locus equations is captured in neural representations and is thus perceptually relevant. We investigated these claims by testing how closely locus equations reflect the production and perception of stop consonants. In Experiment 1, we induced speakers to change their locus equation slope and intercept parameters systematically, but found that consonants remained distinctive in slope-by-intercept space. In Experiment 2, we presented stop-consonant syllables with their bursts removed to listeners, and compared their classification error matrices with the predictions of a model using locus equation prototypes and with those of an exemplar-based model that usesF2 ons andF2 vowel, but not locus equations. Both models failed to account for a large proportion of the variance in listeners’ responses; the locus equation model was no better in its predictions than the exemplar model. These findings are discussed in the context of the OOC. 相似文献

Occupational violence may be an issue in a number of workplaces, and be of two main sources—those sites where cash is handled, and sites with aggressive clients. Legal requirements make it mandatory for an employer to provide a safe workplace, but just how controllable is occupational violence? A risk management equation is developed to assist the manager to ascertain the level of risk for violence in the workplace. 相似文献

This study examined the effects of variant versus invariant high-probability (high-p) request sequences on the performance of requests to initiate a social bid by young children with emotional-behavioral disorders. In the initial phases of the investigation, a multiple baseline design showed that the delivery of invariant sequences (i.e., high-p requests delivered in the same sequence) produced initial increases in compliance to requests to initiate a social bid to a peer. However, increases were not maintained across the invariant condition. The delivery of variant high-p sequences produced increases in compliance to requests to initiate social bids that were maintained across the variant condition. In a follow-up condition, the number of requests within the pool of the variant and invariant high-p requests were controlled. Results of the follow-up condition replicated those found in the initial condition. Implications for applied use and future research are discussed. 相似文献

As John Locke pointed out, there are at least two sources of the contents of the mind: events that occur in the world and events that originate in the mind. Memory, as a record of experience, should contain information from both sources. The present studies investigated memory for the frequency of externally and internally generated events. Individual items were presented to subjects varying numbers of times and tested varying numbers of times. Later, subjects were asked to estimate the frequency of both types of events. Experiment 1 showed that internally generated events influenced the judged frequency of externally generated events and vice versa. The first of these was called the IFE effect and the second the IFI effect. Experiment 2 indicated that the IFE effect was greater when tests consisted of overt, as compared to covert, recall trials. The results were discussed in terms of a model for storing and using occurrence information which would account for both our ability to discriminate between and our tendency to confuse internally and externally generated memory representations. 相似文献

Two letters varying in level of confusability were presented either simultaneously for 75 msec or sequentially for 75 msec each in adjacent retinal locations. The retinal locus of presentation varied from trial to trial, and subjects both identified and located the presented letters. Identification accuracy was higher on nonconfusable than on confusable letter pairs in the simultaneous condition, but not in the sequential condition. This result is interpreted as support for the notion that inhibition between similar or identical features shared by confusable letters occurs only when letters are presented simultaneously. A relative position effect, with performance on the peripheral letter higher than on the central letter, was found for simultaneously and second sequentially presented letters, but not for first sequentially presented letters. This result is interpreted in terms of the assumption that feature perturbations, with foveal perturbations more likely than peripheral perturbations, affect simultaneously and secondpresented letters, but not first-presented letters. The pattern of results for relative location accuracy showed many of the same effects as identification performance. A model assuming location errors reflect feature transpositions is outlined and is able to account for the absolute and relative location results and the correlation between relative location and identification accuracy. 相似文献

This paper proposes that test-taking behavior can be regarded as a kind of self-presentation formally identical to that which goes on in most social interaction. It follows from this analysis that the success of such self-presentations should be affected by the actor's role-taking ability or empathy. Evidence is presented that supports this conjecture; the paper then suggests that role-taking ability may limit in a systematic manner validity coefficients in much assessment research. 相似文献

Psychological androgyny and personality adjustment in college and psychiatric populations 总被引:1,自引:0,他引:1
In two separate studies, 106 female and 84 male undergraduates and 48 female and 48 male psychiatric inpatients were administered the Bem Sex Role Inventory (BSRI) and the Faschingbauer Abbreviated Minnesota Multiphasic Personality Inventory. The masculine, feminine, androgynous, and undifferentiated groups identified from the BSRI differed on a variety of personality scales in both normal and clinical populations. Androgynous females were significantly lower on the Depression (D) and Social Introversion (Si) scales than feminine females, and, in the college sample, were also lower on the Schizophrenia and Mania scales than masculine females. In the hospitalized male sample, this pattern was partially sustained, with androgynous and masculine subjects being significantly less deviant than feminine on the Si scale, and tending to score lower on the D scale. In the group of college males, androgynous males scored lower on the Si scale than feminine males. Hypotheses concerning the relationship of sex-role flexibility (androgyny) to mental health appear to be supported for females in both college and psychiatric populations by these results. These results also indicate that sex-role conformity may relate differently to personality development and psychological functioning for males and females. 相似文献

Three experiments examined young children's ability to evaluate the relationship between concepts as one of inclusion. In Experiment 1, the same group of 4-to 7-year-old children were given three tasks: one in which they made judgments about whether “all” or “some” members of a category were included in another category, and two tasks in which they made inferences based on knowledge of inclusion relations. The majority of children succeeded on at least one of the tasks, thereby implying that they could evaluate inclusion relations. Two further experiments provided more evidence for this hypothesis: Experiment 2 confirmed that nursery children could answer quantitative questions about conceptual interrelationts; Experiment 3 demonstrated that nursery schoolers could solve certain inference problems involving the construction and evaluation of hierarchies. 相似文献
