Delay discounting is a stable trait measure of impulsivity. Engaging in episodic future thinking (EFT) can reduce discounting, but whether individual differences in discounting are associated with differences in future thinking remains unclear. Here, this association was tested in healthy adolescents (= 49, age range = 12–16 years, fluent German speakers, from a large German city). Data collection was between December 2011 and December 2012. Vividness of EFT (assessed via the Autobiographical Memory Interview) was negatively correlated with discounting (= ?.41, 95% CI [?.63, ?.13], r2 = .17). Regression analyses confirmed that this association was stable when controlling for additional variables, including hormonal measures of pubertal maturation and intelligence. EFT may attenuate impulsivity in young people at risk of engaging in problematic behavior.  相似文献

Failure to delay gratification may not indicate poor control or irrationality, but might be an adaptive response. Two studies investigated 3.5‐ and 4.5‐year‐old children's ability to adapt their delay and saving behavior when their preference (e.g., to delay or not delay) became nonadaptive. In Study 1 (= 140), children's delay preference was associated with a risk of losing rewards. In Study 2 (= 142), children's saving preference was associated with an inability to play an attractive game. Whereas baseline delaying and saving preferences were unrelated to a standardized executive function measure, children who switched to their nonpreferred choice scored higher, suggesting flexibility of decision‐making may be a more meaningful dependent variable than baseline performance in developmental research on self‐control.  相似文献

Children (predominantly white and middle class) between 3 and 6 years (= 55.12 months, = 145 at Time 1, N = 102 at Time 2) participated in the prosocial choice test at two time points approximately 10 months apart. Children could share with strangers, close friends, nonfriends, and in a control, no recipient condition. Children shared more rewards with friends over time. Age interacted with recipient type such that older children had a higher probability of prosocial allocations toward friends and strangers compared to younger children. Theory of mind (ToM) predicted more prosocial allocations to friends over time, and the youngest children with higher ToM scores showed the largest increase in sharing with friends over time.  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

Age‐related differences in temporal discounting (TD) and risk taking, and their association, were examined in adolescents and young adults (= 337) aged 12–27 years. Since monetary rewards are typically used in TD and risk‐taking tasks, the association between monetary reward valuation and age and decision making in these tasks was explored as well. TD declined linearly with age, with a particularly sharp decline from 15 to 16 years. In contrast, risk taking was not correlated with age and TD. Reward valuation was not associated with TD and risk taking, and age‐related differences in TD remained significant after controlling for reward valuation. Together, these findings suggest that risk taking and TD are two separate constructs with distinct age‐related differences in adolescence and young adulthood.  相似文献

This study investigated age-dependent improvements of monitoring and control in 7/8- and 9/10-year-old children. We addressed prospective (judgments of learning and restudy selections) and retrospective metacognitive skills (confidence judgments and withdrawal of answers). Children (N = 305) completed a paired-associate learning task twice, with a 1-year delay. Results revealed improvements in retrospective, but not in prospective monitoring and control. Furthermore, control remained suboptimal, seemingly a consequence of overoptimistic monitoring. Both age groups showed stronger monitoring-based control at the second compared to the first assessment. The comparison with a cross-sectional sample (N = 144) revealed that improvements in retrospective monitoring can be mainly attributed to naturally occurring development, whereas retrospective control seemed to improve due to increased task familiarity.  相似文献

To evaluate the role of temperamental task orientation in adolescents' academic success, we examined its relation to educational accomplishments in high school and college using longitudinal data. Participants (N = 110) were assessed at 15, 16, and 17 years of age with a follow-up at 24 years. Adolescent self-report and parent reports of task orientation at 16 were used to predict high school and college GPA, SAT scores, perseverance in college, and degree attainment. Task orientation related to high school GPA and accounted for variance above and beyond SES and IQ in predicting high school and college GPA. An interaction emerged between IQ and task orientation: increasing levels of task orientation were associated with higher GPA for students with higher intelligence, but not for those with relatively lower intelligence. These findings highlight the contribution of non-intellective factors to academic achievement in secondary and post-secondary education.  相似文献

Inequalities are everywhere, yet little is known about how children respond to people affected by inequalities. This article explores two responses—minimizing inequalities and favoring those who are advantaged by them. In Studies 1a (N = 37) and 1b (N = 38), 4‐ and 5‐year‐olds allocated a resource to a disadvantaged recipient, but judged advantaged recipients more positively. In Studies 4 (N = 38) and 5 (N = 74), a delay occurred between seeing the inequality and allocating resources, or stating a preference, during which time participants forgot who was initially more advantaged. Children then favored advantaged recipients on the preference and resource allocation measures, suggesting an implicit “affective tagging” mechanism drives the tendency to favor the advantaged. In contrast, reducing inequalities through resource allocation appears to require explicit reasoning.  相似文献

The susceptibility to gaze cueing in deaf children aged 7–14 years old (N = 16) was tested using a nonlinguistic task. Participants performed a peripheral shape-discrimination task, whereas uninformative central gaze cues validly or invalidly cued the location of the target. To assess the role of sign language experience and bilingualism in deaf participants, three groups of age-matched hearing children were recruited: bimodal bilinguals (vocal and sign-language, N = 19), unimodal bilinguals (two vocal languages, N = 17), and monolinguals (N = 14). Although all groups showed a gaze-cueing effect and were faster to respond to validly than invalidly cued targets, this effect was twice as large in deaf participants. This result shows that atypical sensory experience can tune the saliency of a fundamental social cue.  相似文献

This report compares the effects (concurrent and lagged) of the anticipated rewards and costs of violent crime on engagement in severe violence in a sample of male juvenile offenders (N = 1,170; 42.1% black, 34.0% Hispanic, 19.2% white, and 4.6% other; ages 14–18 at baseline). Anticipated rewards (social approval, thrill) are more predictive of concurrent severe violence than are anticipated costs (social disapproval, risk of punishment). The analysis finds no evidence that perceptions of the rewards and costs of violent crime influence engagement in severe violence 6 months later. The results support the view that adolescence is a time of heightened reward salience but raise doubt about the longitudinal predictive validity of perceptions about crime during this time of life.  相似文献

The goal was to examine the scope and development of early visual memory durability. We investigated individual- and age-related differences across three unique tasks in 6- to 12-month-olds (Mage = 8.87, N = 49) by examining the effect of increased delay on memory performance. Results suggest longer-term memory processes are quantifiable by 8 months using a modified Change Detection paradigm and spatial-attention cueing processes are quantifiable by 10 months using a modified Delayed Response paradigm, utilizing 500–1,250 ms delays. Performance improved from 6 to 12 months and longer delays impaired performance. We found no evidence for success on the Delayed Match Retrieval task at any age. These outcomes help inform our understanding of infant visual memory durability and its emergence throughout early development.  相似文献

Children need to learn to persist through challenges, yet adults sometimes step in to solve problems for them. Here, we looked at how adult taking over related to children’s persistence. In an observational study (N = 34, ages 4–8), we found that parents who took over more often during a challenging puzzle task rated their children as dispositionally less persistent. To establish whether taking over can cause reduced persistence, we ran two preregistered experiments (N = 150, ages 4–5). Children assigned to a taking over condition persisted less on a subsequent task compared to those in a teaching or a baseline condition. Reframing the context did not ameliorate the negative impact of taking over. The results suggest that taking over impairs children’s persistence.  相似文献

Children's ability to flexibly shift attention between different representational schemes was investigated using the dimensional change card sorting task. Across three experiments (N = 56 three‐year‐olds and N = 40 four‐year‐olds in 2 ; N = 14 three‐year‐olds in 3 ; and N = 14 three‐year‐olds in 4 ) the role of perceptual information on children's cognitive flexibility was investigated by manipulating different aspects of the task materials between pre‐ and postswitch phases. Better performance was observed when either task‐relevant (the color or shape of the images on the cards) or task‐irrelevant information (the background color or shape of the actual cards) was changed, with this improvement occurring when the changes were salient enough to induce a stimulus novelty effect.  相似文献

Adolescence is an important time for social development during which friendships become more intimate and complex. In this functional magnetic resonance imaging (fMRI) study we tested how outcomes for friends are processed on the neural level across adolescence. Participants between 8 and 27 years of age were tested twice with a 2‐year difference between the first (N = 299) and second (N = 254) time points. Participants performed a task in which they could win and lose money for themselves and their best friend. Mixed linear models revealed a linear decrease in activity in social brain regions for friend > self over development. These results confirm changes in the social brain network across adolescent development, we further show that individual differences are related to these neural changes.  相似文献

Previous research suggests that people encode gender starting in childhood. The present research asked whether gender diverse children (i.e., children whose gender identity or expression differs from that expected based on assigned sex) encode gender. Results showed that 3- to 5-year-old gender diverse participants (N = 71), siblings of gender diverse children (N = 52), and gender conforming controls (N = 69) did not significantly differ in degree of gender encoding. These results converge with prior research to suggest that gender diverse children process gender in ways that do not differ from gender conforming children, and provide further evidence that gender encoding may be a common aspect of person perception in societies that support a binary view of gender.  相似文献

This investigation examined parental scaffolding of children’s prospective control over decisions and actions during a joint perception-action task. Parents and their 6-, 8-, 10-, and 12-year-old children (N = 128) repeatedly crossed a virtual roadway together. Guidance and control shifted from the parent to the child with increases in child age. Parents more often chose the gap that was crossed and prospectively communicated the gap choice with younger than older children. Greater use of an anticipatory gap selection strategy by parents predicted more precise timing of entry into the gap by children. This work suggests that social interaction may serve as an important experiential mechanism for the development of prospective control over decisions and actions in the perception–action domain.  相似文献

Deficits in numerical magnitude perception characterize the mathematics learning disability developmental dyscalculia (DD), but recent studies suggest the relation stems from inhibitory control demands from incongruent visual cues in the nonsymbolic number comparison task. This study investigated the relation among magnitude perception during differing congruency conditions, executive function, and mathematics achievement measured longitudinally in children (n = 448) from ages 4 to 13. This relation was investigated across achievement groups and as it related to mathematics across the full range of achievement. Only performance on incongruent trials related to achievement. Findings indicate that executive function in a numerical context, beyond magnitude perception or executive function in a non-numerical context, relates to DD and mathematics across a wide range of achievement.  相似文献

To learn language, children must map variable input to categories such as phones and words. How do children process variation and distinguish between variable pronunciations (“shoup” for soup) versus new words? The unique sensory experience of children with cochlear implants, who learn speech through their device's degraded signal, lends new insight into this question. In a mispronunciation sensitivity eyetracking task, children with implants (N = 33), and typical hearing (N = 24; 36–66 months; 36F, 19M; all non-Hispanic white), with larger vocabularies processed known words faster. But children with implants were less sensitive to mispronunciations than typical hearing controls. Thus, children of all hearing experiences use lexical knowledge to process familiar words but require detailed speech representations to process variable speech in real time.  相似文献

The pervasive income–achievement gap has been attributed in part to deficiencies in executive functioning (EF). The development of EF is related to children's planning ability, an aspect of development that has received little attention. Longitudinal data from the National Institute of Child Health and Human Development study of early child care show that early childhood poverty (1 and 24 months) is significantly related to fifth grade, math, and reading achievement (n = 1,009). The ability to plan in Grade 3, indexed by the Tower of Hanoi task, mediates the income–achievement gap in math and to a lesser extent in reading. IQ was incorporated as a statistical control throughout.  相似文献

Jigsaw puzzles are ubiquitous developmental toys in Western societies, used here to examine the development of metarepresentation. For jigsaw puzzles this entails understanding that individual pieces, when assembled, produce a picture. In Experiment 1, 3- to 5-year-olds (N = 117) completed jigsaw puzzles that were normal, had no picture, or comprised noninterlocking rectangular pieces. Pictorial puzzle completion was associated with mental and graphical metarepresentational task performance. Guide pictures of completed pictorial puzzles were not useful. In Experiment 2, 3- to 4-year-olds (N = 52) completed a simplified task, to choose the correct final piece. Guide-use associated with age and specifically graphical metarepresentation performance. We conclude that the pragmatically natural measure of jigsaw puzzle completion ability demonstrates general and pictorial metarepresentational development at 4 years.  相似文献
