The goal of the present study was to ascertain whether individual differences in self‐esteem, self‐confidence, assertiveness and number of siblings could predict young children's responses to cross‐examination style questioning. Five‐ and 6‐year‐old children (N = 137) participated in a unique staged event and were then interviewed with analogues of direct and cross‐examination. Despite highly accurate direct examination reports, children made a large number of changes to these reports during cross‐examination, resulting in a significant decrease in accuracy. Poor cross‐examination performance was associated with low levels of teacher‐rated self‐confidence, self‐esteem and assertiveness, raising concern that the children who are likely to fare poorly during cross‐examination may be the very children who are most likely to appear as witnesses in the courtroom. Furthermore, number of siblings was inversely related to cross‐examination performance. Further research is required to pinpoint the specific mechanism(s) behind this finding.

ABSTRACT— Mammals, including humans, show sex differences in juvenile play behavior. In rodents and nonhuman primates, these behavioral sex differences result, in part, from sex differences in androgens during early development. Girls exposed to high levels of androgen prenatally, because of the genetic disorder congenital adrenal hyperplasia, show increased male-typical play, suggesting similar hormonal influences on human development, at least in females. Here, we report that fetal testosterone measured from amniotic fluid relates positively to male-typical scores on a standardized questionnaire measure of sex-typical play in both boys and girls. These results show, for the first time, a link between fetal testosterone and the development of sex-typical play in children from the general population, and are the first data linking high levels of prenatal testosterone to increased male-typical play behavior in boys. 相似文献

The goal of the present research is to demonstrate, and then alleviate, the role of thought suppression in depressing women’s math performance under stereotype threat. We hypothesize that when taking a math test, women (but not men) attempt to suppress thoughts of the math-related gender stereotype. Suppression leads to underperformance when it uses up cognitive resources. In Study 1, women underperform on a math test and show postsuppressional rebound of the stereotype when cognitive resources are reduced. In Study 2, women suppress the stereotype after a math test begins, but show rebound when the test is complete. In Study 3, making the stereotype irrelevant to the test improves performance and reduces postsuppressional rebound. In Studies 4 and 5, we test a strategy women can use to make suppression easier, and show that it restores math performance. Theoretical and practical implications are discussed. 相似文献

In-depth interviews were conducted with 42 women and men (aged 22–62 years) to explore their relationships with their bodies. The particular focus was age-related changes in body image and attitudes toward the body aging, an area that has received little research attention to date. Thematic analysis revealed distinctive gender differences. Men commonly conceptualized their bodies as a holistic entity, whereas women commonly had compartmentalized conceptualizations. They also construed the importance of their bodies differently: men tended to focus on functionality, and women tended to focus on display. These findings may help to explain gendered consequences of body dissatisfaction. Accounts about the aging of the body support a “double standard of aging.” Women viewed aging most negatively in terms of its impact on appearance, whereas men reported a neutral or even positive impact on appearance. 相似文献

The main purpose of this study was to explore the relation between teacher expectations and student achievement in physical education classes, in the light of three complementary hypotheses. Student achievement may confirm teacher expectations because these expectations create self‐fulfilling prophecies, create perceptual biases, or accurately predict, without influencing, student achievement (Jussim, 1989 ). Another purpose was to examine the mediating role played by students' perceived ability in the teacher expectancy process. Study data were obtained from 173 students and 7 teachers. Path analysis revealed that teacher expectations have weak self‐fulfilling effects, strongly predicted student achievement mainly because they are accurate, and have no biasing effects on teacher judgements. Results also show evidence concerning the role of partial mediator of perceived student ability in the confirmation process of teacher expectations. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献

Reinforcement, instruction giving, partner support strategies, bedtime routine, and standard extinction were taught to the parents of three boys (aged 5–10 years) with an intellectual disability and sleeping difficulties. Sleep was measured using sleep diaries and actigraphy, and daytime behaviour was monitored using diaries and direct observation. At referral, all children needed a parent present to fall asleep, two had co‐sleeping difficulties, and two had night waking difficulties. At post‐intervention, all children were falling asleep independently, co‐sleeping was eliminated for two children, and night waking was reduced in one child. An extinction burst was experienced by two children, with one family putting their child back to bed 259 times on the first night. Though one child still had night waking difficulties following intervention, actigraph recording demonstrated an improvement in his sleep quality. In addition to the children's independence, improvements were seen for sleep length, sleep latency, and morning wake time. However, improvements in daytime behaviour showed inconsistency across behaviours and settings. Improvement in sleep was maintained at a three month follow‐up. It was concluded that using extinction to address sleep problems in children with an intellectual disability is effective and approved of by parents, but any impact on daytime behaviour is equivocal.

Williams syndrome (WS) is a genetic disorder which results in an uneven cognitive profile. Despite superior language compared to other syndromes in the phenotypic outcome, toddlers with WS are as delayed in their language onset and early linguistic development as are toddlers with other syndromes. The cause of this delay in WS is as yet unknown. In a series of experiments, we examined whether atypical socio‐interactive precursors to language could contribute to the explanation of the late language onset and atypical developmental pathways observed in WS. Experiment 1 showed that despite superficially good social skills, toddlers with WS were only proficient at dyadic interaction. They were impaired in triadic interaction, essential for the referential uses of language, and showed none of the correlations between socio‐interactive markers and language seen in the typical controls. Experiment 2 focused on the comprehension and production of referential pointing. Again, the WS group was impaired, despite vocabulary levels higher than those of typically developing controls. Finally, Experiment 3 examined fine motor skills. The WS lack of pointing could not be explained in terms of motor impairments, since the WS toddlers were proficient at fine motor control, such as the pincer grip. Overall, our data indicate that the early stages of WS language follow an atypical pathway. The findings challenge the frequent claims in the literature that individuals with Williams syndrome have preserved linguistic and social skills. 相似文献

Probed recall tasks are often used to assess aspects of children's verbal short-term memory development because they are not subject to potentially confounding output effects. However, the marked recency effects that are observed in probed recall means that these tasks are potentially insensitive to experimental manipulations when later serial positions are probed. This clouds the interpretation of data from probed recall studies in which children of different ages are presented with to-be-remembered lists of different lengths. In two experiments we examined the magnitude of phonological similarity and lexicality effects in both 5- to 6- and 8- to 9-year-old children. In each case performance on probed recall tasks was contrasted with that seen on tests of serial recognition. The results indicated that probed recall tasks are potentially less sensitive to experimental manipulations in younger than older children. However, comparable effects of both phonological similarity and lexicality were seen in both age groups using serial recognition procedures. These findings have implications for the interpretation of other studies that have examined the development of verbal short-term memory using probed recall and for theoretical accounts of the development of phonological similarity and lexicality effects in children. 相似文献

A randomised, double-blind, placebo-controlled, between subjects study design (N=37) was used to investigate the effects of dexamphetamine on explicit new name learning. Participants ingested 10mg of dexamphetamine or placebo daily over 5 consecutive mornings before learning new names for 50 familiar objects plus fillers. The dexamphetamine group recognised and recalled the new names more accurately than the placebo group over the 5 days and 1 month later. Word learning success was not associated with baseline neuropsychological performance, mood, cardiovascular arousal, or sustained attention. These results may have implications for the pharmacological treatment of acquired naming difficulties. 相似文献

The current study examined the persistence and phenotypic presentation of inattention/overactivity (I/O) into early adolescence,
in a sample of institution reared (IR) children adopted from Romania before the age of 43 months. Total sample comprised 144
IR and 21 non-IR Romanian adoptees, and a comparison group of 52 within-UK adoptees, assessed at ages 6 and 11 years. I/O
was rated using Rutter Scales completed by parents and teachers. I/O continued to be strongly associated with institutional
deprivation, with continuities between ages 6 and 11 outcomes. There were higher rates of deprivation-related I/O in boys
than girls, and I/O was strongly associated with conduct problems, disinhibited attachment and executive function but not
IQ more generally, independently of gender. Deprivation-related I/O shares many common features with ADHD, despite its different
etiology and putative developmental mechanisms. I/O is a persistent domain of impairment following early institutional deprivation
of 6 months or more, suggesting there may be a possible pathway to impairment through some form of neuro-developmental programming
during critical periods of early development. 相似文献
