This study examined the effects of rewards on the ideational fluency of 75 preschool children. Assigned to a reward or nonreward condition, the children were administered two ideational fluency tasks, Unusual Uses and Pattern Meanings. Analyses revealed a significant main effect for reward on the ideational fluency components of originality, total fluency, and flexibility. In all cases the rewarded subjects scored lower than the nonrewarded group. These findings support the growing body of evidence that rewards are detrimental to creative functioning. 相似文献

A first step towards the design and implementation of a successful mainstreaming program requires a careful examination of two key issues. First, what are children's attitudes towards disability, and second, what are the critical elements involved in facilitating attitude change? This paper examines the current research literature on children's attitudes towards disability and programs aimed at attitude change. The review culminates in a synthesis of the key themes and issues involved and provides a foundation for further study. 相似文献

Twenty acquisition curves were obtained from each of 8 pigeons in a free-operant choice procedure. Every condition began with a phase in which two response keys had equal probabilities of reinforcement, and, as a result, subjects’ responses were divided fairly evenly between the two keys. This was followed by a phase in which one key had a higher probability of reinforcement than the other, and the development of preference was observed. In all but a few cases, response proportions increased for the key with the higher probability of reinforcement. In most conditions, the two probabilities differed by .06, but the actual probabilities varied (from .16 and .10 in one condition to .07 and .01 in another). Development of preference for the key with the higher probability of reinforcement was slower when the ratio of the two reinforcement probabilities was small (.16/.10) than when it was large (.07/.01). This finding is inconsistent with the predictions of several different quantitative models of acquisition, including the kinetic model (Myerson & Miezin, 1980) and the ratio-invariance model (Horner & Staddon, 1987). However, the finding is consistent with a hypothesis based on Weber’s law, which states that the two alternatives are more discriminable when the ratio of their reinforcement probabilities is larger, and, as a result, the acquisition of preference is faster. 相似文献

A census and survey of schools in the district of Ga, Ghana, explored the nature and extent of private education, and compared
inputs to public and private schooling. Three quarters of all schools found were private, with almost as many unregistered
private as government schools. Several important differences between registered and unregistered private schools were noted,
including age, fee levels charged, teacher salaries and class size. A range of inputs, such as teacher activity, availability
of desks, chairs, libraries, toilets and drinking water, were used to compare inputs to government, unregistered and registered
private schools. Some conclusions are explored about the potential role for the private sector in helping meet “education
for all” targets. 相似文献

ABSTRACTResearch Findings: Continuity of care is a recommended practice in child care intended to promote secure and supportive relationships between infants and toddlers and their caregivers. Toddlers (N = 115) between 12 and 24 months were observed in 30 continuity and 29 noncontinuity classrooms. The average duration of care for toddlers with caregivers was 14 months in the continuity rooms and 5 months in noncontinuity rooms. Toddlers observed in continuity rooms experienced higher levels of interactive involvement with their caregivers and were rated by their caregivers as having fewer problem behaviors compared with the toddlers in noncontinuity rooms. Toddlers in rooms with higher staff–child ratios also experienced more involved caregiving. We did not find evidence that the level of involved caregiving mediated the association between continuity of care and toddlers’ social competence or problem behaviors. Practice or Policy: Continuity of care may be a promising practice for programs that strive to provide high-quality care for infants and toddlers. 相似文献

Parent-daughter transmission of the androgen receptor gene as an explanation of the effect of father absence on age of menarche 总被引:2,自引:0,他引:2
Based on an evolutionary theory of socialization, Belsky and colleagues proposed that girls exposed to a stressful environment, especially when due to father absence in the first 7 years of life, showed an early onset of puberty, precocious sexuality, and unstable relationships as adults. The authors of this article examined an alternative explanation that a variant X-linked androgen receptor (AR) gene, predisposing the father to behaviors that include family abandonment, may be passed to their daughters causing early puberty, precocious sexuality, and behavior problems. The results of a study of 121 White males and 164 White females showed a significant association of the short alleles of the GGC repeat polymorphism of the AR gene with a range of measures of aggression and impulsivity, increased number of sexual partners, sexual compulsivity, and lifetime number of sex partners in males; and paternal divorce, father absence, and early age of menarche in females. These findings support a genetic explanation of the Belsky psychosocial evolutionary hypothesis regarding the association of fathers' absence and parental stress with early age of onset of menarche and early sexual activity in their daughters. A genetic explanation of the father absence effect is proposed in which fathers carrying the AR alleles are more likely to abandon a marriage (father absence) and pass those alleles to their daughters in whom they produce an earlier age of menarche and behavioral problems. 相似文献

Recent demographic trends and growth in the public sector of higher education have created severe strains for many private liberal arts colleges. The population ecology model, which explains the survival or demise of organizations in terms of their ability to negotiate for resources in their environment, provides a framework for assessing predictors of continued success among colleges. A three-way discriminant analysis based on the population ecology framework and other empirical research led to the successful classification of almost 72% of a sample of colleges in terms of their experiences during the 1970s. Number of departments, median state income, library holdings per enrollee, sectarian affiliation, annual tuition, Roman Catholic affiliation, and SAT composite score were found to be major predictors. 相似文献
