Three-, four-, and five-year-old children's categorical and comparative understanding of high and low were examined in two experiments. Categorical knowledge was assessed by presenting subjects with a single object at varying heights (from 0 to five feet above the ground), and asking if the object was high or low. Comparative understanding of the terms was assessed by showing children two objects at a time and asking which was higher or lower. We observed two patterns of performance in children's categorical treatments: younger children in particular defined disjoint categories for high and low such that they only labelled the extreme heights as high or low, and maintained that middle heights were neither high nor low. Older children defined either-or categories such that all heights were labelled either high or low. We also found that children who defined either-or categories made correct comparative judgments across the entire range of variation whereas children who defined disjoint categories could only judge which of two objects was higher if the objects were not low (at 0 and 1 feet) and which of the objects was lower if the objects were not high (at 4 and 5 feet). The results were interpreted as reflecting a lack of appreciation that the terms are interdefined as negations of each other, and were discussed in terms of the similar semantic-congruity effects found in adults.  相似文献

The purposes of this study were to evaluate the effects of self-monitoring on increasing the on-task behaviors of four at-risk middle school students, and to examine its indirect effects on academic performance. Additionally, we attempted to develop and validate cost- and time-efficient procedures that typical classroom teachers could use. The data from a multiple baseline design across three academic settings, replicated with four students, revealed immediate increases in on-task behavior as each student began to self-monitor in each sequential setting. The data also revealed slightly higher levels of academic performance and, in most instances, gradually accelerating trends. These findings suggest that self-monitoring is a cost- and time-efficient procedure that classroom teachers can use to teach at-risk students to manage their own behaviors.  相似文献

Examined the effectiveness of an HIV intervention program among 151 adolescents ages 13 to 24 years who were randomly assigned to (a) seven sessions of 1.5 hr each (10.5 hr); (b) three sessions of 3.5 hr each (10.5 hr); or (c) a no-intervention condition. Using cognitive-behavioral intervention strategies, social skills and HIV-related beliefs, perceptions, and norms were targeted in both the three- and seven-session, small-group intervention conditions. Regression analysis indicated that over 3 months, the number of unprotected risk acts and the number of sexual partners were lower in the seven-session condition compared to the other conditions. Factors mediating risk acts changed in a complex manner: For example, perceived vulnerability increased for those with initially lower vulnerability scores among youths in the seven-session condition compared to others. Self-approval of condom use was also higher for those with initially low scores in the seven-session compared to the three-session condition. Self-efficacy for risk avoidance and condom use was significantly higher in the three-session condition for those with initially low scores compared to other groups. On the role-play measure, those with higher baseline scores in the low-pressure situation improved significantly only in the three-session intervention; in the high-pressure situation, the participants reported significantly higher scores in the seven-session intervention, and those with higher scores improved the most. Results suggest the importance of multisession HIV intervention programs to be delivered with fidelity in community settings.  相似文献

This study examines data from questionnaires to establish the prevalence and correlates of women's binge drinking, defined as four or more drinks per episode, at women's colleges ( n = 508) and at coeducational colleges ( n = 9,624). Results showed that women at women's colleges binged less frequently, had fewer alcohol-related problems, experienced fewer negative effects of others' drinking, and were less likely to drink and drive. The correlates of binge drinking were similar for the two groups of women. The differences appear to be related not to the quantity or amount of socializing but to its quality. The absence of fraternities and coeducational dormitories, the reduced likelihood of a party-centered lifestyle, and self-selection factors at women's colleges all may contribute to a healthier environment for women. Interventions designed to lower the risk of college binge drinking should further explore the peer-group contexts in which problem drinking is reduced.  相似文献

Consistent evidence demonstrates that many women who encounter the trauma of rape experience a range of both acute reactions and chronic psychological sequelae. This article reviews both the short- and long-term psychological adjustment issues associated with rape. In addition, we propose a culturally inclusive ecological model of sexual assault recovery (CIEMSAR), which integrates and extends existing models to better examine the complex factors leading to differential postrape adjustment. Important components of the CIEMSAR are placing rape in the broader sociocultural context of the United States and explicated socioracial and ethnic factors influencing the recovery process. The five primary factors of CIEMSAR are outlined, including (a) macrosystem or sociocultural context factors; microsystem/individual factors such as (b) assault characteristics, (c) person variables, (d) coping responses; and mesosystems factors such as (e) social-support systems. Suggestions for future research are also provided.  相似文献

The Personality Inventory for Children-Revised (PIC-R) is a parent-report measure of social-emotional adjustment for children 3 to 16 years of age. The present study examined the clinical value of the PIC-R by exploring the impact of age and developmental status on PIC-R profiles, particularly on the Psychosis (PSY) scale, within a sample of preschool and school-age children referred for assessment of suspected cognitive impairment and learning problems. Compared to school-age children, significantly more preschoolers obtained elevated scores on the Psychosis scale; those preschoolers with cognitive impairments were even more likely to obtain significantly elevated Psychosis scale scores, despite the absence of diagnosed childhood psychosis. No significant relationship was found between Psychosis scale elevations and cognitive impairment in the school-age group. The PIC-R was moderately accurate in identifying cognitively impaired preschoolers but only minimally accurate in identifying cognitively impaired school-age children.  相似文献

This study tested the hypothesis that the moderate correlation between optimism (O) and pessimism (P) scores (their non-bipolarity) found in earlier studies may be an artifact of the differential sensitivity of O and P items to two response sets: defensive pessimism and Pollyannaism. The data failed to support either component of the hypothesis. Thus, defensive pessimists, as measured in two quite different ways, had lower depression scores (BDI) than genuine pessimists, but contrary to prediction, had higher depression scores than optimists. Moreover, deleting P items with a strong defensive quality from the P scale failed to increase the correlation between O and P scores. Similarly, controlling Pollyannaism by a partial correlation procedure failed to increase the strength of the relation between O and P. The results in general support the notion that optimism and pessimism are not polar opposites. This article is based on a dissertation presented by the senior author to the Division of Graduate Studies and Research of the University of Cincinnati in partial fulfillment of the Doctor of Philosophy degree.  相似文献

Most previous research on sex differences in experienced aggression has confounded the sex of the aggressor and of the target by considering married or dating couples. In the present study, black and white male and female college students were asked about specific acts of aggression which they had received from or directed toward a male or female. As predicted, males were likely to have both received and exhibited more forms of aggressive behavior, although females were somewhat more likely to have been honked at, to have been forced by a male to have sex, and to have slapped someone. Few racial differences were found, but it appeared that blacks might have been relatively more likely to exhibit physical aggression and whites to exhibit nonphysical aggression. Some differences were found in specific behaviors directed toward and received from males and females, but in general subjects said that they received more aggressive behaviors than they directed toward others. © 1992 Wiley-Liss, Inc.  相似文献
