The Family Adaptability and Cohesion Evaluation Scales (FACES), a measure of family functioning, contains three scales: cohesion, adaptability, and social desirability. These were slightly modified (FACES- R) on the basis of pilot data and were administered to 42 clinic families (families seeking or receiving psychological services) and 206 nonclinic families. Support for the scales was found in high coefficient alpha reliabilities and similarity of the sample means and standard deviations to those of the standardization sample. However, there was little agreement among family members' scale scores. Therapists' ratings of cohesion and adaptability did not correlate with scale scores among clinic families. There was no difference between clinic and nonclinic samples on the cohesion or adaptability scales, although the social desirability scale did discriminate between groups. Factor analysis suggested that cohesion, adaptability, and social desirability cannot be clearly differentiated using this measure.This work was supported by the American Association of University Women and by Grant R01HD13820 from the National Institute of Child Health and Human Development.  相似文献

Nine- and eleven-year-old children differing in reading proficiency read and commented on brief expository passages containing three different types of embedded problems (nonsense words, prior knowledge violations, and internal inconsistencies). Half of the children were specifically instructed as to the types of standards they should apply in order to detect the problems (lexical, external consistency, and internal consistency); the remaining children were simply instructed to look for problems. Both quantitative and qualitative differences in standard use were revealed by the children's comments about all parts of the passages. Older and better readers used more different standards and they used them more frequently than younger and poorer readers. The lexical standard was more likely to be adopted spontaneously than the other two standards and it was the only standard used by a substantial proportion of both younger and poorer readers. Finally, the consistent effects of instruction type indicate that children's evaluation activities were strongly influenced by the amount of guidance received.  相似文献

The functional significance of learned population differences in male song in the white-crowned sparrow was explored in natural populations using playback tests. Laboratory results have shown that learning of the population-specific song seems to take place in early life and is strongly dependent upon the nature of the auditory experience at that time. However, the varied results of recent studies make it difficult to reach a confident conclusion about the ecological functions of song learning. The present research took advantage of naturally occurring variation in the differences between songs of adjacent populations to determine a function relating degree of difference in song to intensity of territorial singing elicited. Applying a typological evaluation of syllable structure to the four segments of the song allowed a crude quantitative ranking of the differences between local songs and playback stimuli. These results, together with those of other studies, suggest a unimodal aggressive response function of males to songs of other males. A maximum response to songs slightly different from the local song environment suggests that male exclusion based upon acquired song components may contribute to the maintenance of discrete and stable song dialects.  相似文献

The attractiveness bias suggests that people who are more attractive will be positively favored across life outcomes. This study sought to test whether candidate attractiveness, sex, and race, affect perceptions of candidate strength in a job recruitment task. In total, 338 White women (Mage = 20.94 ± 5.65) were asked to make judgements of a potential candidate for an administrative job (resume with candidate photograph). The vignettes differed in terms of candidate ability (strong/weak), sex (male/female), race (Black/White), and attractiveness (attractive/less attractive). Participants rated perceived candidate strength and likelihood to invite for interview. Results showed no significant main effects for attractiveness. However, there was a significant interaction for target attractiveness and race, such that attractive/White candidates were more likely to be invited for interview than less attractive/White candidates. There was also a significant main effect for race such that Black candidates were rated as stronger and more likely to be interviewed. Sensitivity analyses (with nonheterosexual women removed from the sample) also showed a main effect for target sex such that female candidates were favored over male candidates. Overall, these findings provide evidence that attractiveness, sex, and race have important, albeit complex, effects on hiring decisions in the workplace.  相似文献

A signal detection measure of visual recognition was used to assess the visual recognition of two-digit numbers in three different conditions: (1) voicing of the number as it was presented visually; (2) voicing of a different number than the one presented; and (3) no voicing. The three treatment means were significantly different, with matched voicing resulting in the best performance and no voicing, in the worst. There was no evidence that the treatments differentially affected response criteria.  相似文献

The CFF was determined with three sectored disks, each of which corresponded to one of the three rings in a Helmholtz disk. The fusion frequency is identical for all three rings of a Helmholtz disk but with the three sectored disks it was found that the rate of stimulus occlusion is a major factor in determining the CFF. It was tentatively concluded that the effect was not a consequence of different stimulus wave-forms. The phenomenon appears to have been reported late in the last century.  相似文献

The widespread use of seclusion and restraint in child psychiatric hospitals to manage aggression and noncompliance is based on the assumption that coercive consequences reduce the frequency of undesirable behaviors exhibited by the patients. We report a study of the use of seclusion and restraint in a public child psychiatric hospital during a 3-year period. Twenty-eight percent of the patients had been secluded or restrained a total of 1670 times. About 25% of these patients had been secluded more than five times during their hospitalization, and 32% had been placed in restraints more than once. Behaviors that typically resulted in repeated seclusion included physical aggression toward staff, verbal aggression toward peers, non-compliant or oppositional behavior, and self-harm. Variables that predicted patients most at risk for repeated seclusion included age, gender, and psychiatric diagnosis. The predictor variables for those most at risk for repeated restraint included age, property destruction, and self-harm. The high rates of use of seclusion and restraint suggest that these methods for controlling the behavior of children and adolescents in this child psychiatric hospital may not have been therapeutic. We suggest that staff in such hospitals engage in a pattern of behavior characterized by an aggression-coercion cycle, in which increasingly aggressive and coercive behaviors are exhibited by both patients and staff.  相似文献

The twin design was used to examine the importance of different experiences of siblings within the family and to identify relations between twins' personality differences and their differential experiences. A sample of 161 monozygotic and 74 dizygotic twin individuals between the ages of 18 and 75 years retrospectively reported on their different experiences when growing up. The Sibling Inventory of Differential Experience (SIDE) was used for the first time with a sample of twin siblings. In addition, the twins provided self-report measures of affect and personality. In contrast to results from a sibling adoption design, this study of twins showed greater evidence for genetic variance in the SIDE scales. Nevertheless, the SIDE showed significant associations with differences in personality and affect for monozygotic twins, which reflect pure environment-behavior relations.  相似文献
