ABSTRACT

Family conversations about science-related topics, including those involving storybook reading, may set the stage for children’s interest in science. We investigated how parents from two cultural backgrounds engaged in science talk while reading a science-related storybook with their preschool-aged daughters and sons. Consistent with our commitment to avoid deficit thinking, our questions focus on variability within a group of European-American parents and a group of Latine parents, rather than comparing groups. Our sample included 38 European-American families (20 girls), and 27 Latine families (12 girls) from three coastal regions of California, varying in educational background. Our results indicate that parents from both groups read most of the text, had conversations beyond the text, and specifically engaged in science talk when elaborating beyond the book with their children. European-American parents with 12–16 years of schooling engaged in science talk more with boys than with girls, whereas the science talk of European-American parents with more than 16 years of schooling did not differ by children’s gender. Latine parents did not differ significantly in their science talk by years of parents’ schooling or by children’s gender. Results are discussed as they relate to current conversations about early socialization of science interest and engagement for boys and girls in diverse families.  相似文献

The aim of the study is to evaluate the usefulness of the Bem Sex Role Inventory (BSRI; Bem, 1974), an overall measurement of the cultural construct of masculinity and femininity, in the psychological assessment of Spanish transsexuals. Seventy male-to-female transsexuals (MF), 51 female-to-male transsexuals (FM), 77 control men, and 79 control women completed the Spanish version of the BSRI. Statistically significant differences between groups were only found on the femininity scale, on which MF transsexuals and control women scored significantly higher than FM transsexuals and control men. The results indicate that (a) only the femininity scale of the BSRI appears to be useful today for evaluating differences in the sex-role identification in Spanish controls and transsexuals; and (b) MF and FM transsexuals score as a function of their gender identity instead of their anatomical sex on the BSRI femininity scale.  相似文献

The study of intimate partner violence among adolescent and young couples in Spain remains unattended, although such abuses are well known and more frequent than in adulthood. The aim of this study is, on the one hand, to provide epidemiological information on dating relationships, and on the other hand, to identify attitudes towards violence. 2205 women enrolled in schools in diverse provinces of Spain, participated in the study. Average age was near 19 years (SD= 2.25). The Dating Violence Questionnaire (DVQ, in Spanish, CUVINO), a questionnaire that assesses both frequency and distress associated with violent behavior, was used. The DVQ allowed differentiating between groups of women self-labeled as abused and not abused on the basis of the frequency of sustained violence, although the levels of distress in the face of violence were statistically similar in both groups. Implications for future research and prevention programs are discussed.  相似文献

Aging has been associated with several brain changes that often affect the cognitive functioning of adults, but changes in executive functions, particularly in the field of decision making, have not been fully investigated. The Iowa Gambling Task (IGT) is a widely used tool to evaluate decision making, but little is known about the effect of age on its results. This study used the IGT and compared healthy young (n = 40) and elderly (n = 40) adults to evaluate their decision making processes. There were significant differences in the learning curve of the two age groups, but no difference in overall IGT performance. The results for the first IGT block were different from those of the rest of the task, and the group of elderly adults had a better performance in this block. Elderly adults also showed a preference for deck A, the one that resulted in greater losses. Findings confirmed the results of other studies, which reported that the IGT block score is the variable with the greatest sensitivity to age in this instrument.  相似文献

The study of sleep deprivation is a fruitful area of research to increase our knowledge of cognitive functions and their neural basis. In the current work, 26 healthy young adults participated in a sleep deprivation study, in which the Attentional Networks Test for Interactions and Vigilance (ANTI-V) was performed at 10a.m. after a night of normal sleep and again at 10 a.m. after 25.5-27.5 h of total sleep deprivation. The ANTI-V is an experimental task that provides measures of alerting, orienting and executive control attentional functions. Compared with previous versions, the ANTI-V includes a vigilance task, more reliable auditory alerting signals, non-predictive peripheral orienting cues, and also a neutral no-cue condition allowing the analysis of reorienting costs and orienting benefits. Thus, new evidence to evaluate the influence of sleep deprivation on attentional functioning is provided. Results revealed differences in both tonic and phasic alertness after sleep deprivation. Vigilance performance was deteriorated, while a warning tone was more helpful to increase participants' alertness, resulting in slightly faster RT and, in particular, fewer errors. The reorienting costs of having an invalid spatial cue were reduced after sleep loss. No sleep deprivation effect on the executive control measure was found in this study. Finally, since no control group was used, particular precautions were taken to reduce the influence of potential practice effects.  相似文献

It remains unclear how memory load affects attentional processes in visual search (VS). No effects, as well as beneficial and detrimental effects of memory load, have been found in this type of task. The main goal of the present research was to explore whether memory load has a modulating effect on VS by means of a different attentional set induced by the order of trials (mixed vs. blocked) and by the time presentation of visual display (long vs. short). In Experiment 1, we randomized the order of type of trial (5, 10 and 15 items presented in the display) while it remained constant (10 items) in Experiments 2A and 2B. In the later experiments, we also changed time presentation of visual display (3000 vs. 1300 ms, respectively). Results showed no differential effects of memory load in Experiments 1 and 2A, but they showed up in Experiment 2B: RTs were longer in the attentional task for trials under high memory load conditions. Although our hypothesis of the attentional set is supported by the results, other theoretical implications are also worth discussing in order to better understand how memory load may modulate attentional processes in VS.  相似文献

The paper makes a twofold contribution. Firstly, it advances a preliminary account of the conditions that need to obtain for constitutional rights to be democratic. Secondly, in so doing, it defends precommitment-based theories from a criticism raised by Jeremy Waldron—namely, that constitutional rights do not become any more democratic when they are democratically adopted, for the people could adopt undemocratic policies without such policies becoming democratic as a result. The paper shows that the reductio applies to political rights, yet not to non-political rights, such as reproductive, environmental, or privacy rights. The democratic status of the former is process-independent. The latter, by contrast, are democratic precisely when they are adopted by democratic means.  相似文献

The purpose of this study was to delimit the psychological and social disturbances that individuals who have suffered psychological abuse within a social group on an ongoing basis can experience. A comprehensive classification of these disturbances was developed based on a review of the scientific literature. Its content was revised by an international panel of 38 experts on the topic. Experts also judged the frequency and intensity with which each disturbance is commonly experienced by survivors of abusive groups. The taxonomy, which includes 20 components classified into four main categories, showed adequate content validity. The components considered the most frequent and intense were related to emotional difficulties, followed by those associated with relational and social integration difficulties, cognitive difficulties, and, finally, other specific problematic behaviors. Operationalizing and classifying the specific psychological and social disturbances commonly experienced by survivors of abusive groups contributes to a better delimitation of the phenomenon. Likewise, it contributes to the understanding of the long-term effects of psychological abuse, which is useful in both the academic and clinical settings.  相似文献
