Three studies examined the role of stereotype threat in boys' academic underachievement. Study 1 (children aged 4–10, n = 238) showed that girls from age 4 years and boys from age 7 years believed, and thought adults believed, that boys are academically inferior to girls. Study 2 manipulated stereotype threat, informing children aged 7–8 years (n = 162) that boys tend to do worse than girls at school. This manipulation hindered boys' performance on a reading, writing, and math test, but did not affect girls' performance. Study 3 counteracted stereotype threat, informing children aged 6–9 years (n = 184) that boys and girls were expected to perform similarly. This improved the performance of boys and did not affect that of girls. 相似文献

Preserving the Past: An Early Interview Improves Delayed Event Memory in Children With Intellectual Disabilities 
下载免费PDF全文
下载免费PDF全文 The influence of an early interview on children's (N = 194) later recall of an experienced event was examined in children with mild and moderate intellectual disabilities (CWID; 7–12 years) and typically developing (TD) children matched for chronological (7–12 years) or mental (4–9 years) age. Children previously interviewed were more informative, more accurate, and less suggestible. CWID (mild) recalled as much information as TD mental age matches, and were as accurate as TD chronological age matches. CWID (moderate) recalled less than TD mental age matches but were as accurate. Interviewers should elicit CWID's recall as early as possible and consider developmental level and severity of impairments when evaluating eyewitness testimony. 相似文献

The strategies children employ to selectively attend to different parts of the face may reflect important developmental changes in facial emotion recognition. Using the Moving Window Technique (MWT), children aged 5–12 years and adults (N = 129) explored faces with a mouse‐controlled window in an emotion recognition task. An age‐related increase in attention to the left eye emerged at age 11–12 years and reached significance in adulthood. This left‐eye bias is consistent with previous eye tracking research and findings of a perceptual bias for the left side of faces. These results suggest that a strategic attentional bias to the left eye begins to emerge at age 11–12 years and is likely established sometime in adolescence. 相似文献

This study aimed to test a four-wave sequential mediation model linking mother–child attachment to children's school readiness through child executive functioning (EF) and prosociality in toddlerhood and the preschool years. Mother–child attachment security was assessed when children (N = 255) were aged 15 months and 2 years, child EF at age 2, prosocial behavior at age 4, and finally cognitive school readiness in kindergarten (age 6). The results revealed three indirect pathways linking attachment to school readiness: one through EF only, one through prosocial behavior only, and a last pathway involving both EF and prosocial behavior serially. These findings suggest that secure attachment may equip children with both cognitive and social skills that are instrumental to their preparedness for school. 相似文献

This prospective study examined the latent growth trajectories of sensory patterns among a North Carolina birth cohort (N = 1517; 49% boys, 87% White) across infancy (6–19 months), preschool (3–4 years), and school years (6–7 years). Change rates of sensory hyper- and hyporesponsiveness better differentiated children with an autism diagnosis or elevated autistic traits from those with other developmental conditions, including non-autistic children with sensory differences. More sensory hyper- and hyporesponsiveness at infancy followed by steeper increases differentially predicted more autistic traits at school age. Further, children of parents with higher education tended to show stable or improving trajectories. These findings highlight the importance of tracking sensory patterns from infancy for facilitating early identification of associated challenges and tailored support for families. 相似文献

Four studies (N = 192) tested whether young children use nonverbal information to make inferences about differences in social power. Five‐ and six‐year‐old children were able to determine which of two adults was “in charge” in dynamic videotaped conversations (Study 1) and in static photographs (Study 4) using only nonverbal cues. Younger children (3–4 years) were not successful in Study 1 or Study 4. Removing irrelevant linguistic information from conversations did not improve the performance of 3‐ to 4‐year‐old children (Study 3), but including relevant linguistic cues did (Study 2). Thus, at least by 5 years of age, children show sensitivity to some of the same nonverbal cues adults use to determine other people's social roles. 相似文献

Distinguishing between equity and equality is essential when making social and moral decisions, yet the related neurodevelopmental processes are unknown. Evaluations of contextually based third‐party distributions incorporating recipient need and resource importance were examined in children and adolescents (N = 82; 8–16 years). Spatiotemporal neurodynamic responses show distinct developmental profiles to viewing such distributions. Event‐related potentials (ERPs) differentially predicted real‐life behaviors based on age, where older children's (8–10 years) evaluations were related to a fairly rapid, automatic ERP component (early posterior negativity), whereas adolescent and preadolescent (11–16 years) evaluations, first‐person allocations, and prosocial behaviors were predicted by later, cognitively controlled ERP components (P3 and late positive potential). Together, these results reveal age‐related changes regarding the neural responses that correspond to distributive justice decisions. 相似文献

Prior research points to gender differences in some early language skills, but is inconclusive about the mechanisms at play, providing evidence that both infants' early input and productions may differ by gender. This study examined the linguistic input and early productions of 44 American English-learning infants (93% White) in a longitudinal sample of home recordings collected at 6–17 months (in 2014–2016). Girls produced more unique words than boys (Cohen's d = .67) and this effect grew with age, but there were no significant gender differences in language input (d = .22–.24). Instead, caregivers talked more to infants who had begun to talk (d = .93–.97), regardless of gender. Therefore, prior results highlighting gender-based input differences may have been due, at least partly, to this talking-to-talkers effect. 相似文献

Children's Increased Emotional Egocentricity Compared to Adults Is Mediated by Age‐Related Differences in Conflict Processing 下载免费PDF全文
下载免费PDF全文 This study investigated the cognitive mechanisms underlying age‐related differences in emotional egocentricity bias (EEB) between children (aged 7–12 years, n = 30) and adults (aged 20–30 years, n = 30) using a novel paradigm of visuogustatory stimulation to induce pleasant and unpleasant emotions. Both children and adults showed an EBB, but that of children was larger. The EEB did not correlate with other measures of egocentricity. Crucially, the developmental differences in EEB were mediated by age‐related changes in conflict processing and not visual perspective taking, response inhibition, or processing speed. This indicates that different types of egocentricity develop independently of one another and that the increased ability to overcome EEB can be explained by age‐related improvements in conflict processing. 相似文献

In human adults, visual dominance emerges in several multisensory tasks. In children, auditory dominance has been reported up to 4 years of age. To establish when sensory dominance changes during development, 41 children (6–7, 9–10, and 11–12 years) were tested on the Colavita task (Experiment 1) and 32 children (6–7, 9–10, and 11–12 years) were tested on the sound‐induced flash illusion (Experiment 2). In both experiments, an auditory dominance emerged in 6‐ to 7‐year‐old children compared to older children. Adult‐like visual dominance started to emerge from 9 to 10 years of age, and consolidated in 11‐ to 12‐year‐old children. These findings show that auditory dominance persists up to 6 years, but switches to visual dominance during the first school years. 相似文献

Children and adolescents (N = 153, ages 8–14 years, Mage = 11.46 years) predicted and evaluated peer exclusion in interwealth (high-wealth and low-wealth) and interracial (African American and European American) contexts. With age, participants increasingly expected high-wealth groups to be more exclusive than low-wealth groups, regardless of their depicted race. Furthermore, children evaluated interwealth exclusion less negatively than interracial exclusion, and children who identified as higher in wealth evaluated interwealth exclusion less negatively than did children who identified as lower in wealth. Children cited explicit negative stereotypes about high-wealth groups in their justifications, while rarely citing stereotypes about low-wealth groups or racial groups. Results revealed that both race and wealth are important factors that children consider when evaluating peer exclusion. 相似文献

The development of language attitudes and perception of talker regional background was investigated across the life span (N = 240, age range = 4–75 years). Participants rated 12 talkers on dimensions of geographic locality, status, and solidarity. Children could classify some dialects by locality by age 6–7 years and showed adult-like patterns by age 8 years. Children showed adult-like status ratings for some dialects by age 4–5 years but were not fully adult-like until age 12 years. Solidarity ratings were more variable and did not exhibit a clear developmental trajectory, although some adult-like patterns were in place by age 6–7 years. Locality ratings were a significant but modest predictor of attitude ratings, suggesting that geographic knowledge is one contributor to language attitudes throughout development. 相似文献

This meta-analysis examined associations between the quantity and quality of parental linguistic input and children’s language. Pooled effect size for quality (i.e., vocabulary diversity and syntactic complexity; k = 35; N = 1,958; r = .33) was more robust than for quantity (i.e., number of words/tokens/utterances; k = 33; N = 1,411; r = .20) of linguistic input. For quality and quantity of parental linguistic input, effect sizes were stronger when input was observed in naturalistic contexts compared to free play tasks. For quality of parental linguistic input, effect sizes also increased as child age and observation length increased. Effect sizes were not moderated by socioeconomic status or child gender. Findings highlight parental linguistic input as a key environmental factor in children’s language skills. 相似文献

Four- to 10-year-olds and adults (N = 205) responded to vignettes involving three individuals with different expectations (high, low, and no) for a future event. Participants judged characters’ pre-outcome emotions, as well as predicted and explained their feelings following three events (positive, attenuated, and negative). Although adults rated high-expectation characters more negatively than low-expectation characters after all outcomes, children shared this intuition starting at 6–7 years for negative outcomes, 8–10 years for attenuated, and never for positive. Comparison to baseline (no expectation) indicated that understanding the costs of high expectations emerges first and remains more robust across age than recognition that low expectations carry benefits. Explanation analyses further clarified this developing awareness about the relation between thoughts and emotions over time. 相似文献

Using data from a subsample of 913 study children and their friends who participated in the NICHD Study of Early Child Care and Youth Development, the interactive contributions of child-reported attribution biases and teacher-reported child emotional intensity (EI) at Grade 4 (M = 9.9 years) to observed child–friend interaction at Grade 6 (M = 11.9 years) were examined. Study children's hostile attribution bias, combined with high EI, predicted more negative child–friend interaction. In contrast, benign attribution bias, combined with high EI, predicted more positive child–friend interaction. The findings are discussed in light of the “fuel” interpretation of EI, in which high-intensity emotions may motivate children to act on their cognitive biases for better or for worse. 相似文献

Accurate time perception is crucial for hearing (speech, music) and action (walking, catching). Motor brain regions are recruited during auditory time perception. Therefore, the hypothesis was tested that children (age 6–7) at risk for developmental coordination disorder (rDCD), a neurodevelopmental disorder involving motor difficulties, would show nonmotor auditory time perception deficits. Psychophysical tasks confirmed that children with rDCD have poorer duration and rhythm perception than typically developing children (N = 47, d = 0.95–1.01). Electroencephalography showed delayed mismatch negativity or P3a event-related potential latency in response to duration or rhythm deviants, reflecting inefficient brain processing (N = 54, d = 0.71–0.95). These findings are among the first to characterize perceptual timing deficits in DCD, suggesting important theoretical and clinical implications. 相似文献

Two studies ask whether scaffolded children (n = 243, 5–6 years and 9–10 years) recognize that assistance is needed to learn to use complex artifacts. In Study 1, children were asked to learn to use a toy pantograph. While children recognized the need for assistance for indirect knowledge, 70% of scaffolded children claimed that they would have learned to use the artifact without assistance, even though 0% of children actually succeeded without assistance. In Study 2, this illusion of self-sufficiency was significantly attenuated when observing another learner being scaffolded. Learners may fail to appreciate artifacts’ opacity because self-directed exploration can be partially informative, such that learning to use artifacts is typically scaffolded instead of taught explicitly. 相似文献

The ability to learn from expectations is foundational to social and nonsocial learning in children. However, we know little about the brain basis of reward expectation in development. Here, 3- to 4-year-olds (N = 26) were shown a passive associative learning paradigm with dynamic stimuli. Anticipation for reward-related stimuli was measured via the stimulus preceding negativity (SPN). To our knowledge, this is the first study to measure an SPN in children younger than age 6. Our findings reveal distinct anticipatory neural signatures for social versus nonsocial stimuli, consistent with previous research in older children. This study suggests an SPN can be elicited in preschoolers and is larger for social than nonsocial stimuli. 相似文献

This study examined whether executive functions impact how flexibly children represent task context in performing repeated sequential actions. Japanese children in Experiments 1 (N = 52; 3–6 years) and 2 (N = 50, 4–6 years) performed sequential actions repeatedly; one group received reminders. Experiment 1 indicated that reminders promote flexible changes in contextual representations. Experiment 2 observed such effects in younger children and showed executive functions were associated with the flexible representation of task context. Reminders did not perfectly compensate for the role of executive functions but wiped out individual differences in executive functions that contribute to children’s acquisition of routines. Therefore, setting goals before context-dependent actions is necessary, but not sufficient, to modulate contextual representations in routines. 相似文献

Latinos are the largest minority group in the United States (U.S. Census, 2014), yet this term comprises individuals from multiple ethnicities who speak distinct varieties of Spanish. We investigated whether Spanish–English bilingual children (N = 140, ages 4–17) use Spanish varieties in their social judgments. The findings revealed that children distinguished varieties of Spanish but did not use Spanish dialects to make third-person friendship judgments until 10–12 years; this effect became stronger in adolescence. In contrast, young children (4–6 years) made friendship judgments based on a speaker's language (English, Spanish). Thus, using language varieties as a social category and as a basis for making social inferences is a complex result of multiple influences for Spanish-speaking children growing up bilingual in the United States. 相似文献
