Developmental Differences in Memory During Early Childhood: Insights From Event‐Related Potentials 
下载免费PDF全文
下载免费PDF全文 Age‐related differences in behavioral and electrophysiological indices of memory were examined in 3‐ to 6‐year‐old children (N = 76). Behaviorally, no differences were observed in children's ability to identify old items; however, 3‐year‐old children were less accurate in correctly rejecting new items, and 3‐ and 4‐year‐old children recalled fewer contextual details compared to 5‐ and 6‐year‐old children. Age‐related differences in electrophysiological measures (800–1,000 ms after stimulus onset) were observed both to items recalled with contextual details, which increased between 3 and 4 years, and items recalled without contextual details, which were greatest in 5‐year‐old children, even after adjusting for global age‐related differences. These findings, interpreted within a dual‐process framework, may suggest changes in both recollection and familiarity processes during early childhood. 相似文献

Individual differences in infant attention are theorized to reflect the speed of information processing and are related to later cognitive abilities (i.e., memory, language, and intelligence). This study provides the first systematic longitudinal analysis of infant attention and early childhood executive function (EF; e.g., working memory, inhibitory control, cognitive flexibility). A group of 5‐month‐olds (n = 201) were classified as short or long lookers. At 24, 36, and 48 months of age, children completed age‐appropriate EF tasks. Infant short lookers (i.e., more efficient information processors) exhibited higher EF throughout early childhood as compared to infant long lookers, even after controlling for verbal ability (a potential indicator of intelligence). These findings are discussed in relation to the emergence of executive attention. 相似文献

Abilities to encode and remember events in their spatiotemporal context (episodic memory) rely on brain regions that mature late during childhood and are supported by sleep. We compared the temporal dynamics of episodic memory formation and the role of sleep in this process between 62 children (8–12 years) and 57 adults (18–37 years). Subjects recalled “what–where–when” memories after a short 1‐hr retention interval or after a long 10.5‐hr interval containing either nocturnal sleep or daytime wakefulness. Although children showed diminished recall of episodes after 1 hr, possibly resulting from inferior encoding, unlike adults, they showed no further decrease in recall after 10.5 hr. In both age groups, episodic memory benefitted from sleep. However, children's more effective offline retention was unrelated to sleep. 相似文献

Trajectories of cognitive and neural development suggest that, despite early emergence, the ability to extract environmental patterns changes across childhood. Here, 5- to 9-year-olds and adults (N = 211, 110 females, in a large Canadian city) completed a memory test assessing what they remembered after watching a stream of shape triplets: the particular sequence in which the shapes occurred and/or their group-level structure. After accounting for developmental improvements in overall memory, all ages remembered specific transitions, while memory for group membership was only observed in older children and adults (age by test-type interaction η2 = .05). Thus, while young children form memories for specifics of structured experience, memory for derived associations is refined later—underscoring that adults and young children form different memories despite identical experience. 相似文献

Maternal Behavior and Socioeconomic Status Predict Longitudinal Changes in Error‐Related Negativity in Preschoolers 下载免费PDF全文

The development self‐regulation has been called a primary task of childhood. One system of self‐regulation, self‐monitoring, is indexed at the level of neural activity as early as preschool as the error‐related negativity (ERN). However, how context elicits developmental changes in neural processes of self‐monitoring like the ERN is not well understood. Here, socioeconomic status (SES) and parenting were tested as environmental influences on ERN development between ages 3 and 4 (N = 119). Results showed the expected increases in ERN between ages 3 and 4 only when both maternal sensitivity and SES were high. This work demonstrates the importance of considering the early environment in order to understand the development of a neural process supporting self‐regulation in young children. 相似文献

This article tests the hypothesis that self-development plays a role in the offset of childhood amnesia; assessing the importance of both the capacity to anchor a memory to the self-concept, and the strength of the self-concept as an anchor. This research demonstrates for the first time that the volume of 3- to 6-year old's specific autobiographical memories is predicted by both the volume of their self-knowledge, and their capacity for self-source monitoring within self-referencing paradigms (N = 186). Moreover, there is a bidirectional relation between self and memory, such that autobiographical memory mediates the link between self-source monitoring and self-knowledge. These predictive relations suggest that the self-memory system is active in early childhood. 相似文献

The Development of Implicit Memory From Infancy to Childhood: On Average Performance Levels and Interindividual Differences 下载免费PDF全文

The present multimethod longitudinal study aimed at investigating development and stability of implicit memory during infancy and early childhood. A total of 134 children were followed longitudinally from 3 months to 3 years of life assessing different age‐appropriate measures of implicit memory. Results from structural equation modeling give further evidence that implicit memory is stable from 9 months of life on, with earlier performance predicting later performance. Second, it was found that implicit memory is present from early on, and no age‐related improvements are found from 3 months on. Results are discussed with respect to the basic brain structures implicit memory builds on, as well as methodological issues. 相似文献

Temporal memory in 7‐year‐olds, 10‐year‐olds, and young adults (N = 78) was examined introducing a novel eye‐movement paradigm. Participants learned object sequences and were tested under three conditions: temporal order, temporal context, and recognition. Age‐related improvements in accuracy were found across conditions; accuracy in the temporal conditions was correlated with conventional time knowledge. Eye movements tracked the veridicality of temporal order memory in adults and 10‐year‐olds seconds before providing memory judgments, suggesting that these movements reflect implicit access to temporal information. Seven‐year‐olds overall did not show this eye‐movement effect, but those who did were more accurate than those who did not. Results suggest that eye movements capture aspects of temporal memory development that precede overt decision processes—with implications for hippocampal development. 相似文献

Dysregulated Fear,Social Inhibition,and Respiratory Sinus Arrhythmia: A Replication and Extension 下载免费PDF全文
下载免费PDF全文 Behavioral inhibition indicates increased risk for development of social anxiety. Recent work has identified a pattern of dysregulated fear (DF), characterized by high fear in low‐threat situations, that provides a more precise marker of developmental risk through early childhood. This study tested a new longitudinal sample of children (n = 124) from ages 24 to 48 months. Replicating prior findings, at 24 months, we identified a pattern of fearful behavior across contexts marked by higher fear to putatively low‐threat situations. DF was associated with higher parental report of social inhibition at 24, 36, and 48 months. Extending prior findings, we observed differences in cardiac physiology during fear‐eliciting situations, suggesting that the neurobiological underpinnings of DF relate to difficulty with regulation. 相似文献

This study examined future-oriented behavior in children (3–6 years; N = 193) from three diverse societies—one industrialized Western city and two small, geographically isolated communities. Children had the opportunity to prepare for two alternative versions of an immediate future event over six trials. Some 3-year-olds from all cultures demonstrated competence, and a majority of the oldest children from each culture prepared for both future possibilities on every trial. Although there were some cultural differences in the youngest age groups that approached ceiling performance, the overall results indicate that children across these communities become able to prepare for alternative futures during early childhood. This acquisition period is therefore not contingent on Western upbringing, and may instead indicate normal cognitive maturation. 相似文献

Episodic prospection is the mental simulation of a personal future event in rich contextual detail. This study examined age-related differences in episodic prospection in 5- to 11-year-olds and adults (N = 157), as well as factors that may contribute to developmental improvements. Participants’ narratives of past, future, and make-believe events were coded for episodic content, and self-concept coherence (i.e., how coherently an individual sees himself or herself) and narrative ability were tested as predictors of episodic prospection. Although all ages provided less episodic content for future event narratives, age-related improvements were observed across childhood, suggesting future event generation is particularly difficult for children. Self-concept coherence and narrative ability each independently predicted the episodic content of 5- and 7-year-olds’ future event narratives. 相似文献

We tested whether changes in attribution processes could account for the developmental differences observed in how children’s use fluency to guide their memory decisions. Children ranging in age from 4 to 9 years studied a list of familiar or unfamiliar cartoon characters. In Experiment 1 (n = 84), participants completed a recognition test during which the perceptual fluency of some items was enhanced using a prime. In Experiment 2 (n = 96), participants completed a source recollection judgment on their recognition decisions. Primed items were recognized at a higher rate than unprimed items. However, while young children rely on fluency for all items, older children use fluency only for unfamiliar items. This pattern came together with a reduction in familiarity-based—but not recollection-based—memory responses. 相似文献

The relation between episodic and semantic memory was examined by testing how semantic knowledge influences children’s episodic memory for events and their locations. Five-, six-, and seven-year-olds (N = 87) engaged in events in a children’s museum designed as a town. Events were semantically congruent or incongruent with the spatial location (e.g., sorting mail at post office vs. grocery store). In addition to this experimental paradigm, a semantic interview assessed children’s semantic knowledge about real-world locations. Accuracy in the experimental paradigm showed that children’s semantic memory influenced memory for locations. Interviews revealed age-related improvements in children’s semantic knowledge. Regression analyses examined factors that best supported episodic memory. These results provide novel insights and highlight the utility of research in naturalistic settings. 相似文献

Twenty‐nine grade‐matched 4th–8th‐grade males, 12 with attention‐deficit/hyperactivity disorder (ADHD) (age M= 12.2 years, SD= 1.48), and 17 without (age M= 11.5, SD= 1.59), completed two working memory tasks (digit span and the Simon game) and three long‐term episodic memory tasks (a personal event memory task, story memory task, and picture recognition task). In line with clinical observations, children with ADHD performed worse than peers on all working memory tasks, but performed as well as or better than peers on long‐term episodic tasks, demonstrating particularly detailed memory for personally experienced past events. Participants' parents also completed questionnaires about their children's memories in daily life. Parents rated children with ADHD lower than children without ADHD on working and semantic memory (e.g., remembering names, spelling, and math), but rated them as high or higher on memory for events. Implications for theory and educational practice are discussed. 相似文献

Young Children's Self‐Concepts Include Representations of Abstract Traits and the Global Self 下载免费PDF全文
下载免费PDF全文 There is debate about the abstractness of young children's self‐concepts—specifically, whether they include representations of (a) general traits and abilities and (b) the global self. Four studies (N = 176 children aged 4–7) suggested these representations are indeed part of early self‐concepts. Studies 1 and 2 reexamined prior evidence that young children cannot represent traits and abilities. The results suggested that children's seemingly immature judgments in previous studies were due to peculiarities of the task context not the inadequacy of children's self‐concepts. Similarly, Studies 3 and 4 revealed that, contrary to claims of immaturity in reasoning about the global self, young children update their global self‐evaluations in flexible, context‐sensitive ways. This evidence suggests continuity in the structure of self‐concepts across childhood. 相似文献

An Examination of the Sibling Training Hypothesis for Disruptive Behavior in Early Childhood 下载免费PDF全文
下载免费PDF全文 Sibling training for disruptive behavior (one sibling teaching another disruptive behavior) is examined during early childhood. We used a conservative, recently developed, statistical model to identify sibling training. Sibling training was operationalized as the cross‐lagged association between earlier child behavior and later sibling behavior, and differentiated from other reasons that contribute to sibling similarity. A three‐wave longitudinal study tracked 916 children (Mage = 3.46, SD = 2.23) in 397 families using multi‐informant data. Evidence for sibling training was found. Earlier younger siblings’ disruptive behavior predicted later lower levels of older siblings’ disruptive behavior. Thus, the sibling training found in early childhood was producing greater dissimilarity, rather than similarity, on disruptive behavior. 相似文献

We examined visual recognition memory and executive functioning (spatial working memory [SWM], spatial planning, rule learning, and attention shifting) in 12‐year‐olds (n = 150) who participated in the Bucharest Early Intervention Project, a randomized controlled trial of foster care for institutionally reared children. Similar to prior reports at 8 years of age, institutionally reared children showed significant deficits in visual recognition memory and SWM. Deficits in attention shifting and rule learning were also apparent at this time point. These data suggest that early experiences continue to shape the development of memory, learning, and executive functioning processes in preadolescence, which may explain broader cognitive and learning difficulties commonly associated with severe early life neglect. 相似文献

The self‐reference effect in memory is the advantage for information encoded about self, relative to other people. The early development of this effect was explored here using a concrete encoding paradigm. Trials comprised presentation of a self‐ or other‐image paired with a concrete object. In Study 1, 4‐ to 6‐year‐old children (N = 53) were asked in each trial whether the child pictured would like the object. Recognition memory showed an advantage for self‐paired objects. Study 2 (N = 55) replicated this finding in source memory. In Study 3 (N = 56), participants simply indicated object location. Again, recognition and source memory showed an advantage for self‐paired items. These findings are discussed with reference to mechanisms that ensure information of potential self‐relevance is reliably encoded. 相似文献

Newborn infants orient preferentially toward face‐like or “protoface” stimuli and recent studies suggest similar reflexive orienting responses in adults. Little is known, however, about the operation of this mechanism in childhood. An attentional‐cueing procedure was therefore developed to investigate protoface orienting in early childhood. Consistent with the extant literature, 5‐ to 6‐year‐old children (n = 25) exhibited orienting toward face‐like stimuli; they responded faster when target location was cued by the appearance of a protoface stimulus than when location was cued by matched control patterns. The potential of this procedure to investigate the development of typical and atypical social perception is discussed. 相似文献
