Two experiments investigated the relative influence of speech and pointing gesture information in the interpretation of referential acts. Children averaging 3 and 5 years of age and adults viewed a videotape containing the independent manipulation of speech and gestural forms of reference. A man instructed the subjects to choose a ball or a doll by vocally labeling the referent and/or pointing to it. A synthetic speech continuum between two alternatives was crossed with the pointing gesture in a factorial design. Based on research in other domains, it was predicted that all age groups would utilize gestural information, although both speech and gestures were predicted to influence children less than adults. The main effects and interactions of speech and gesture in combination with quantitative models of performance showed the following similarities in information processing between preschoolers and adults: (1) referential evaluation of gestures occurs independently of the evaluation of linguistic reference; (2) speech and gesture are continuous, rather than discrete, sources of information; (3) 5-year-olds and adults combine the two types of information in such a way that the least ambiguous source has the most impact on the judgment. Greater discriminability of both speech and gesture information for adults compared to preschoolers indicated small quantitative progressions with development in the ability to extract and utilize referential signals. 相似文献

Short (N21−P27) and long (N130−P200) latency somatosensory evoked potentials (SEPs) and personality [Eysenck Personality Questionnaire (EPQ) and a short-form Sensation Seeking scale (SS)] were investigated in 26 young healthy adults. Various modes of analysis were carried out on the SEPs, including peak-to-peak, root mean square, absolute area and perimeter measures, over various time windows. The amount of SEP variance accounted for by personality correlations depended on the mode of analysis. High Psychoticism and high Sensation Seeking (and to some extent high Extraversion) correlated negatively with measures of SEP amplitude, the relationship being stronger for later SEP components. 相似文献

This research explored the relationship between behavioral intentions to engage in AIDS-risky sexual practices and a variety of variables that are theoretically and/or popularly assumed to be important factors in AIDS prevention. These variables included beliefs and knowledge about AIDS, fear of AIDS, perceived vulnerability of self and others, as well as probability that self and others on one's campus would contract AIDS, perceived efficacy to control exposure to AIDS, self-esteem, general locus of control, and past behavioral reaction to the threat of AIDS. General intention to “do something to protect oneself against AIDS,” and specific behavioral intention to use condoms in vaginal sex were measured and considered as possible proxies for future behavior. Data were collected from 124 black respondents in a southeastern university. In a series of multiple regression analyses, each of these measures of behavioral intentions was “predicted” from the other variables. Results showed that situational efficacy (to protect oneself from AIDS) was the best predictor of general intention, followed by reports of past behavioral changes as a result of the AIDS epidemic, and by knowledge. Proximal fear of AIDS was a negative predictor. For specific intentions, a specific belief about inconvenience in condom use was the best predictor, followed by past behavioral change, followed by knowledge. Normative beliefs, a belief that condoms would prevent disease, and distant threat of AIDS were also significant predictors. Theoretical and policy implications of the findings are discussed. 相似文献

Summary Four experiments investigated the perception of tonal structure in polytonal music. The experiments used musical excerpts in which the upper stave of the music suggested a different key than the lower stave. In Experiment 1, listeners rated the goodness of fit of probe tones following an excerpt from Dubois's Circus. Results suggested that listeners were sensitive to two keys, and weighted them according to their perceived importance within the excerpt. Experiment 2 confirmed that music within each stave reliably conveyed key structure on its own. In Experiment 3, listeners rated probe tones following an excerpt from Milhaud's Sonata No. 1 for Piano, in which different keys were conveyed in widely separate pitch registers. Ratings were collected across three octaves. Listeners did not associate each key with a specific register. Rather, ratings for all three octave registers reflected only the key associated with the upper stave. Experiment 4 confirmed that the music within each stave reliably conveyed key structure on its own. It is suggested that when one key predominates in a polytonal context, other keys may not contribute to the overall perceived tonal structure. The influence of long-term knowledge and immediate context on the perception of tonal structure in polytonal music is discussed. 相似文献

11 instruments for assessing beliefs and attitudes about men or masculinity standards (masculinity ideology) and 6 instruments that assess first-person accounts of gender role conflict, stress, or conformity to masculinity ideology are evaluated in this review. The 17 instruments were all developed in the past 2 decades and peer reviewed, and are readily accessible. An introductory section distinguishes between gender ideology and gender orientation and defines the scope of the first set of 11 scales as indexing the extent to which subjects accept the ideas and beliefs used to justify gender roles and relations. The second set of 6 scales focus on how men individually experience their gender. All scales were systematically evaluated according to whether they include items comparing the sexes or concerning gender relations or items assessing attitudes and beliefs about women. Inclusion of these types of items is noted in a table, along with information on whether the authors assumed one dominant form of masculinity, whether subscales were identified, and the psychometric properties of the scale and subscale. The review suggests that measures of gender orientation and measures of gender ideologies are independent and have differential correlates. Evidence also suggests that gender ideologies about men are distinct from and have differential correlates from gender ideologies about women or about gender relations in general. Items comparing genders should thus be avoided in measures of attitude toward masculinities. Several of the measures have too narrow a definition of masculinity. 相似文献

Black and white adolescent males' perceptions of ideal body size 总被引:2,自引:0,他引:2
A stratified random sample of 496 white (n =337) and black (n =159) adolescent males participated in a survey of ideal body size beliefs. Responses to the questionnaire and a series of nine female and male body size drawings were analyzed using the General Linear Model Analysis of Variance and Categorical Modeling. Using SES and race as independent variables and BMI (kg/m
2)as a covariate, black males were found to prefer a significantly heavier ideal female body size than whites (p <.0001) and also perceived that their parents, female friends, and male friends would select as ideal a significantly heavier female body size than white subjects. Black subjects were 1.9 times (O.R. = 1.88, 95% C.I. = 1.44, 2.47) more likely to select a larger ideal female hip/buttocks size and 1.7 times (O.R. = 1.72, 95% C.I. = 1.25, 2.37) more likely to choose a larger ideal female thigh size than white subjects. Our findings seem to point toward a greater approval and social acceptance of a larger body size for black females by black males.

The Perception of Teasing Scale (POTS): a revision and extension of the Physical Appearance Related Teasing Scale (PARTS) 总被引:11,自引:0,他引:11
This article describes the development and validation of a revised measure for the assessment of history of being teased about physical appearance. Study 1 involved the preliminary psychometric evaluation of the questionnaire on a sample of 227 college women, Two factors emerged: Weight-Related Teasing (WT) and Teasing About Abilities/Competencies (Competency Teasing; CT). The integrity of the factor structure of these two scales was established in Study 2 with a sample of 87 college women. Internal consistency ratios in this sample were also found to be acceptable. In Study 3, 92 college women were administered measures of body image, eating disturbance, and self-esteem to test for convergence with the Perception of Teasing Scale. Subjects also rated teasing items for frequency and effect (e.g., how upset they were by the teasing). Two-week test-retest reliabilities for these measures were acceptable. Weight-Related Teasing correlated to a greater degree with other measures than Competency Teasing. Regression analyses revealed the importance of a frequency versus effect dimension. Findings are discussed in light of recent research on developmental factors in body image and eating disturbance. 相似文献
