Sex Roles - Many young children often exhibit a strong desire to wear extremely gender-typed clothing (appearance rigidity), reflecting their emerging gender identities. However, research on... 相似文献

Cross-lateralisation and increased motor difficulties have been reported in children with attention-deficit/hyperactivity disorder (ADHD). Nevertheless, the question of how crossed (i.e. mixed preference) or uncrossed (i.e. same side preference) lateralisation impacts motor performance in children with ADHD has yet to be examined. In this study, previously validated observational measures of hand and foot preference were used to identify right-handed children with ADHD who display cross- (n = 29) and uncross-lateralisation (n = 31). An uncross-lateralised typically developing (TD) group (n = 32) was also identified, and included as a control. Motor performance was assessed with seven valid and reliable fine and gross motor tasks performed with both preferred and non-preferred limbs. Group, task and sex-related effects were examined. Findings revealed that male (but not female) cross-lateralised children with ADHD performed significantly worse, respectively, in two of the fine motor tasks (spiral tracing [p < .01], and dot filling [p < .05]). Results suggest that cross-lateralised hand and foot preference may affect complex motor skills in male children with ADHD. Furthermore, characteristics of ADHD may manifest differently in male and female children. Findings highlight the importance of considering both hand and foot preference when targeting motor interventions for children with ADHD. 相似文献

In order to evaluate the utility of genetic counseling at the time of first trimester screening in patients with no previously
identified genetic concerns, we reviewed family history data for 700 women seen for genetic counseling in Utah during 2005-2006.
The mean maternal age was 35 years (Range: 16–47 years). The majority of patients seen were non-Jewish Caucasians (90.8%,
634/700). A three-generation pedigree was obtained from each woman by one of two certified genetic counselors and subsequently
classified as “negative” (no birth defects/genetic disorders); “positive” (birth defect or genetic condition with a minimal/low
risk of recurrence; additional evaluation/genetic testing during pregnancy not indicated); or “significant” (birth defect
or genetic condition with an increased risk of recurrence; additional evaluation/genetic testing during the pregnancy indicated).
About 72% (501/700) of the histories were negative, 19% (134/700) were positive, and about 9% (65/700) were significant. Among
patients with significant family histories, 66% (n = 43) were women less than 35 years of age. We conclude that assessing a patient’s family history at the time of first trimester
serum screening is a valuable resource for pregnancy management. 相似文献

Here we explore whether mental training in the form of meditation can help to overcome age-related attentional decline. We compared performance on the attentional blink task between three populations: A group of long-term meditation practitioners within an older population, a control group of age-matched participants and a control group of young participants. Members of both control groups had never practiced meditation. Our results show that long-term meditation practice leads to a reduction of the attentional blink. Meditation practitioners taken from an older population showed a reduction in blink as compared to a control group taken from a younger population, whereas, the control group age-matched to the meditators’ group revealed a blink that was comparatively larger and broader. Our results support the hypothesis that meditation practice can: (i) alter the efficiency with which attentional resources are distributed and (ii) help to overcome age-related attentional deficits in the temporal domain. 相似文献

Whether human infants spontaneously represent number remains contentious. Clearfield & Mix (1999 ) and Feigenson, Carey & Spelke (2002 ) put forth evidence that when presented with small sets of 1–3 items infants may preferentially attend to continuous properties of stimuli rather than to number, and these results have been interpreted as evidence that infants may not have numerical competence. Here we present three experiments that test the hypothesis that infants prefer to represent continuous variables over number. In Experiment 1, we attempt to replicate the Clearfield & Mix study with a larger sample of infants. Although we replicated their finding that infants attend to changes in contour length, infants in our study attended to number and perimeter/area simultaneously. In Experiments 2 and 3, we pit number against continuous extent for exclusively large sets (Experiment 2) and for small and large sets combined (Experiment 3). In all three experiments, infants noticed the change in number, suggesting that representing discrete quantity is not a last resort for human infants. These results should temper the conclusion that infants find continuous properties more salient than number and instead suggest that number is spontaneously represented by young infants, even when other cues are available. 相似文献

Young people in Catalonia are studied in order to better understand differences between satisfaction with spirituality and
satisfaction with religion. Results suggest a reactive position on the part of most Spanish youngsters towards traditional
religion; they consider it not very important either for their well-being or to give a sense of meaning to their own lives.
While the importance given to spirituality is clearly higher, the concept seems to have several very different interpretations
among young people. The discussion underlines the importance of discovering young people’s own points of view in order to
understand the meaning they give to religion and spirituality in the context of an ever more rapidly changing society. The
implications for future research and practice are discussed. 相似文献

Aims. This study investigated the effect of simulated visual impairment on the speed and accuracy of performance on a series of commonly used cognitive tests. Methods. Cognitive performance was assessed for 30 young, visually normal subjects (M=22.0±3.1 years) using the Digit Symbol Substitution Test (DSST), Trail Making Test (TMT) A and B and the Stroop Colour Word Test under three visual conditions: normal vision and two levels of visually degrading filters (VistechTM) administered in a random order. Distance visual acuity and contrast sensitivity were also assessed for each filter condition. Results. The visual filters, which degraded contrast sensitivity to a greater extent than visual acuity, significantly increased the time to complete (p<.05), but not the number of errors made, on the DSST and the TMT A and B and affected only some components of the Stroop test. Conclusions. Reduced contrast sensitivity had a marked effect on the speed but not the accuracy of performance on commonly used cognitive tests, even in young individuals; the implications of these findings are discussed. 相似文献

ABSTRACT Although the role of emotional processing is central to contemporary models of risky decision making, to date the role of trait emotional understanding has not been explored experimentally in this context. The current experiment ( N =326) explores the role of alexithymia with respect to performance on the standard Iowa Gambling Task (IGT) and a version where cumulative financial feedback is obscured. Standard learning on the IGT was observed for those low in alexithymia. Those high in alexithymia learned to avoid disadvantageous decks over the first half of the task. However, over the later trials they showed a change in performance, shifting from advantageous to disadvantageous and back to advantageous decks again (termed an "explore-learn-change-return" strategy). It is argued that this is due to an inability to fully consolidate earlier learning and reduced sensitivity to losses. The absence of cumulative feedback independently resulted in reduced performance. 相似文献

ABSTRACT We tested the structure and magnitude of genetic and environmental influences on the overlap among self-esteem, negative emotionality, and major depression symptoms in adolescent girls ( N =706) from the Minnesota Twin Family Study. Genetic and environmental influences on all three operated via a general, heritable factor. Genetic influences explained the majority of overlap among the three constructs, as well as most of the variance in self-esteem and negative emotionality. Genetic influences on depression were more modest and largely due to genetic factors specific to depression. These findings support the theory that self-esteem, depression, and neuroticism represent aspects of a common temperamental core. The interrelations among the three constructs in mid-adolescence is consistent with their interrelations in adulthood. 相似文献

In the first part of this paper I characterize a minimal form of self-consciousness, namely pre-reflective self-consciousness. It is a constant structural feature of conscious experience, and corresponds to the consciousness of the self-as-subject that is not taken as an intentional object. In the second part, I argue that contemporary cognitive neuroscience has by and large missed this fundamental form of self-consciousness in its investigation of various forms of self-experience. In the third part, I exemplify how the notion of pre-reflective self-awareness can be of relevance for empirical research. In particular, I propose to interpret processes of sensorimotor integration in light of the phenomenological approach that allows the definition of pre-reflective self-consciousness. 相似文献
