Long-term recall is influenced by what originally was encoded as well as by the efficacy of retrieval processes. The possible explanatory role of post-encoding processes by which initially labile memory traces are stabilized and integrated into long-term memory (i.e., consolidated) has received relatively less research attention. In the current research, we examined 3- and 4-year-old children's recall of multi-step event sequences immediately after seeing them modeled as a measure of encoding, 1week later as a measure of the status of the memory trace post-encoding, and 1month later as an assessment of long-term recall. We tested recall of events with three different levels of internal structure and with three different levels of support for retrieval. Measures of the post-encoding status of the memory trace explained significant variance in long-term recall when they were the sole predictors of performance, and they contributed unique variance in long-term recall even after accounting for the variance associated with encoding. The results imply that a complete explanation of forgetting during childhood must include not only roles for encoding and retrieval processes but also roles for post-encoding processes. 相似文献

Family-based interventions targeting parenting factors, such as parental monitoring and parent–child communication, have been
successful in reducing adolescent offenders’ substance use and delinquency. This pilot, exploratory study focuses on family
and parenting factors that may be relevant in reducing juvenile offenders’ substance use and sexual risk taking behavior,
and in particular examines the role of family emotional involvement and responsiveness in young offenders’ risk-taking behaviors.
Participants included 53 juvenile drug court offenders and their parents. Results indicate that poor parent–child communication
is associated with marijuana use and unprotected sexual activity for young offenders; however, family affective responsiveness
is also a significant unique predictor of unprotected sexual activity for these youth. Findings suggest that interventions
focused on improving parent–child communication may reduce both marijuana use and risky sexual behavior among court-involved
youth, but a specific intervention focused on improving parents and young offenders’ ability to connect with and respond to
one another emotionally may provide a novel means of reducing unprotected sexual risk behaviors. 相似文献

In this research, we examined overall performance and gender differences in measurement skills in elementary-school students from low-income families. In Study 1, accuracy and error patterns were analyzed in a large sample of fourth-graders; in Study 2 error patterns and strategy usage were examined with a smaller sample of fourth-graders. Study 1 showed no main effect of gender on students’ performance. Instead, as predicted, the direction of gender difference varied as a function of problem type: boys outperformed girls on spatial/conceptual measurement, whereas girls outperformed boys on formula-based measurement, as well as on a test of computation skills. Study 2 revealed both similarities and differences in the way boys and girls approached measurement problems. Girls appeared to have specific difficulty with spatial/conceptual problems where objects and measurement units were not pictorially presented. When recording their solutions, girls generally wrote down calculations while boys made drawings. Overall, the students performed poorly in measurement; strategy analysis allowed for examination of common weaknesses, indicating possible ways of improving performance of underserved groups. 相似文献

The experience of social rejection can lead to an aggressive response. However, the ability to maintain a sense of social connection may reduce the likelihood of this type of response. We tested a computer-based intervention designed to use simple learning principles to boost the sense of social connection and acceptance. Adolescents aged 9–15 (n=138) first completed a conditioning game on computer that repeatedly paired their own name with images of social acceptance (versus a control condition with no systematic pairing), and subsequently reported how aggressively they would behave in response to being rejected by a peer. Those completing the self-acceptance conditioning (particularly those low in self-esteem) reported less aggressive feelings and intentions. 相似文献

It is surprising how easily we are able to recognize people whom we have not seen in many years, somehow compensating for the aging-related facial changes that occurred. We measured the limits of the ability to recognize faces across the lifespan by young versus old men and women. Images of five males and five females at young and middle ages were morphed in 10% increments to create aged face images across the lifespan. Fifty-eight participants (28 females) judged whether pairs of photographs were of the same or different identity. Women outperformed men for female faces, exhibiting a sex difference and own-sex bias. Additionally, older participants showed an own-age bias and outperformed their younger counterparts with older stimuli. It appears that the recognition of faces is affected by the own-age and own-sex biases, potentially allowing us to remember some people better than others, thus mediating our interaction with the world. 相似文献

ABSTRACTWe examined recall of events by children 4–11 years to inform patterns of retention of autobiographical memories as well as factors that predict their survival. 101 children participated in a 4-year prospective study. At study inception, children were 4, 6, and 8 years. They were tested annually for three more years for a total of four waves of data collection. At each wave, we obtained narrative reports of recent (all waves) and distant (Waves 2–4) events, resulting in virtually continuous sampling of memories formed by 4- to 11-year-olds and recalled after 1–3-year delays. We also measured children's language, and domain-general and memory-specific cognitive skills. Multi-level modelling revealed age-related increases in the likelihood of survival of memories over the delays. Critically, the rate of increase in retention of individual memories was the same across the cohorts. In addition to age, thematic coherence of original memory reports predicted memory survivability. Other factors were not predictive. The dense sampling and prospective tracking of memories across the 4–11-year age period permitted an especially strong test for continuity versus discontinuity in autobiographical memory across the second half of the first decade of life. The data are strongly indicative of continuity and gradual change. 相似文献

Across five experiments we examined the role of valence in children's and adults’ true and false memories. Using the Deese/Roediger-McDermott paradigm and either neutral or negative-emotional lists, both adults’ (Experiment 1) and children's (Experiment 2) true recall and recognition was better for neutral than negative items, and although false recall was also higher for neutral items, false recognition was higher for negative items. The last three experiments examined adults’ (Experiment 3) and children's (Experiments 4 and 5) 1-week long-term recognition of neutral and negative-emotional information. The results replicated the immediate recall and recognition findings from the first two experiments. More important, these experiments showed that although true recognition decreased over the 1-week interval, false recognition of neutral items remained unchanged whereas false recognition of negative-emotional items increased. These findings are discussed in terms of theories of emotion and memory as well as their forensic implications. 相似文献

This cross-cultural study investigates the impact of background experience on four verbal and visuo-spatial working memory (WM) tasks. A total of 84 children from low-income families were recruited from the following groups: (1) Portuguese immigrant children from Luxembourg impoverished in terms of language experience; (2) Brazilian children deprived in terms of scholastic background; (3) Portuguese children from Portugal with no disadvantage in either scholastic or language background. Children were matched on age, gender, fluid intelligence, and socioeconomic status and completed four simple and complex span tasks of WM and a vocabulary measure. Results indicate that, despite large differences in their backgrounds and language abilities, the groups exhibited comparable performance on the visuo-spatial tasks dot matrix and odd-one-out and on the verbal simple span task digit recall. Group differences emerged on the verbal complex span task counting recall with children from Luxembourg and Portugal outperforming children from disadvantaged schools in Brazil. The study suggests that whereas contributions of prior knowledge to digit span, dot matrix, and odd-one-out are likely to be minimal, background experience can affect performance on counting recall. Implications for testing WM capacity in children growing up in poverty are discussed. 相似文献
