Binding is key in multisensory perception. This study investigated the audio‐visual (A‐V) temporal binding window in 4‐, 5‐, and 6‐year‐old children (total N = 120). Children watched a person uttering a syllable whose auditory and visual components were either temporally synchronized or desynchronized by 366, 500, or 666 ms. They were asked whether the voice and face went together (Experiment 1) or whether the desynchronized videos differed from the synchronized one (Experiment 2). Four‐year‐olds detected the 666‐ms asynchrony, 5‐year‐olds detected the 666‐ and 500‐ms asynchrony, and 6‐year‐olds detected all asynchronies. These results show that the A‐V temporal binding window narrows slowly during early childhood and that it is still wider at 6 years of age than in older children and adults.  相似文献

This study tested the prediction that, with age, children should rely less on familiarity and more on expertise in their selective social learning. Experiment 1 (N = 50) found that 5‐ to 6‐year‐olds copied the technique their mother used to extract a prize from a novel puzzle box, in preference to both a stranger and an established expert. This bias occurred despite children acknowledging the expert model's superior capability. Experiment 2 (N = 50) demonstrated a shift in 7‐ to 8‐year‐olds toward copying the expert. Children aged 9–10 years did not copy according to a model bias. The findings of a follow‐up study (N = 30) confirmed that, instead, they prioritized their own—partially flawed—causal understanding of the puzzle box.  相似文献

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

Four studies (= 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

When tested in the Deese–Roediger–McDermott paradigm, children typically exhibit fewer false memories than do adolescents or adults. Here, participants’ moods and the valence of word lists were manipulated to explore the mechanism responsible for this developmental reversal in memory performance. Children (7‐ to 8‐year‐olds), adolescents (11‐ to 12‐year‐olds), and young adults (18‐ to 22‐year‐olds; N = 270) were assigned to one of three induced mood conditions and were presented with emotional word lists. In negative moods, adolescents and adults falsely recalled more negative information than did children, showing the typical developmental reversal effect. This effect, however, was eliminated when participants were in positive moods. The findings provide support for associative‐activation theory and have important implications for our understanding of the development of emotional false memories.  相似文献

The Supports Intensity Scale–Children's Version (SIS‐C) was developed to assess the support needs of children and youth aged 5 to 16 years with intellectual and developmental disabilities. Data from the standardization sample of the SIS‐C were analyzed to evaluate the impact of the age cohorts (5–6, 7–8, 9–10, 11–12, 13–14, and 15–16 years) used to stratify the sample on the measurement model, as well as the latent means, standard deviations, and correlations. The findings confirmed measurement invariance across age cohorts, but suggested that at the latent level, younger children, generally, have more intensive support needs and that as students with intellectual disability age, their support needs decrease. In addition, the 15‐ to 16‐year‐old cohort displayed differences in terms of the strength of correlations between support need domains, with stronger correlations than the other age groups. Implications for future research and practice are described.  相似文献

Power differences are observed in children's early relationships, yet little is known about how children conceptualize social power. Study 1 recruited adults (= 35) to assess the validity of a series of vignettes to measure five dimensions of social power. Using these vignettes, Study 2 (149 three‐ to nine‐year‐olds, 42 adults) and Study 3 (86 three‐ to nine‐year‐olds, 22 adults) showed that children visiting a science museum at a middle class university town are sensitive to several dimensions of social power from a young age; however, an adult‐like breadth of power concepts does not develop until 7–9 years. Children understand social power whether the powerful character is malevolent or benevolent, though malevolent power is easier to detect for children and adults.  相似文献

The purpose of this study was to ascertain whether children with summer birthdates, or the youngest children within their respective grades, comprised a larger portion of an annual elementary‐age special education referral population than would be expected by chance. The 1,222 referrals from grades K‐5 of a Southeastern school district were classified according to three seasons of birth (months 6‐9, 10‐1, and 2‐5), three age groups (ages 5‐7, 8‐9, and 10 and up), and gender. Expected numbers of referrals for each season of birth were computed based on the numbers of children within the respective groups for the overall elementary‐age school population of 16,379. Independent chi‐square analyses revealed differences at the <.0001 level of significance between the expected and obtained numbers of referrals for both the 5‐ to 7‐year‐old children overall and the 5‐ to 7‐year‐old boys, and at the .0011 level of significance for 5‐ to 7‐year‐old girls. No significant differences between the expected and obtained numbers of referrals were found for the two older groups. Alternative means for providing educational services for the younger, at‐risk primary‐age student population were discussed. © 2000 John Wiley & Sons, Inc.  相似文献

This research asks whether analogical processing ability is present in human infants, using the simplest and most basic relation—the same–different relation. Experiment 1 (= 26) tested whether 7‐ and 9‐month‐olds spontaneously detect and generalize these relations from a single example, as previous research has suggested. The attempted replication failed. Experiment 2 asked whether infants could abstract the relation via analogical processing (Experiment 2, = 64). Indeed, with four exemplars, 7‐ and 9‐month‐olds could abstract the same–different relation and generalize it to novel pairs. Furthermore, prior experience with the objects disrupted learning. Facilitation from multiple exemplars and disruption by individual object salience are signatures of analogical learning. These results indicate that analogical ability is present by 7 months.  相似文献

An investigation was conducted into the visual and auditory temporal processing profiles of two groups of 4‐ to 6‐year‐old children: pre‐alphabetic children, who showed no alphabetic ability (failing to read any non‐words in a test), and those who demonstrated some alphabetic ability. This alphabetic group showed higher scores in reading and spelling attainment than the pre‐alphabetic group. They were also faster than the pre‐alphabetic group in reacting to the onset and offset of auditory and visual stimuli. However, when age was used as a covariate, only reaction times (RTs) to the offsets of visual stimuli were found to be faster in the alphabetic than the pre‐alphabetic group. This suggests that responses to the offset of visual stimuli are becoming more rapid during the same developmental period when alphabetic ability is beginning to be acquired. Within the alphabetic group, after accounting for age, visual and auditory onset RTs were strongly correlated, whereas within the pre‐alphabetic group there were high correlations between visual and auditory offset RTs. It is therefore suggested that a strong association between RTs to visual and auditory onsets may be beneficial during early alphabetic acquisition, when phoneme–grapheme associations are established. Multiple regression analyses showed visual offset RT as the only variable to account for a significant amount of variance in spelling attainment after age was taken into account, which may relate to Frith's (1985) contention that spelling is important in driving early alphabetic ability.  相似文献

Three experiments examined 4‐ to 6‐year‐olds' use of potential cues to geographic background. In Experiment 1 (N = 72), 4‐ to 5‐year‐olds used a speaker's foreign accent to infer that they currently live far away, but 6‐year‐olds did not. In Experiment 2 (N = 72), children at all ages used accent to infer where a speaker was born. In both experiments, race played some role in children's geographic inferences. Finally, in Experiment 3 (N = 48), 6‐year‐olds used language to infer both where a speaker was born and where they currently live. These findings reveal critical differences across development in the ways that speaker characteristics are used as inferential cues to a speaker's geographic location and history.  相似文献

Do children believe that “everything happens for a reason?” That is, do children endorse purpose‐based, teleological explanations for significant life events, as they do for social behavior, artifacts, biological properties, and natural kinds? Across three experiments, 5‐ to 7‐year‐olds (= 80), 8‐ to 10‐year‐olds (= 72), and adults (= 91) chose between teleological and nonteleological accounts of significant life events and judged how helpful those accounts were for understanding an event's cause. Five‐ to 7‐year‐olds favored teleological explanations, but this preference diminished with age. Five‐ to 7‐year‐olds and 8‐ to 10‐year‐olds also found teleological explanations more helpful than did adults. Perceiving purpose in life events may therefore have roots in childhood, potentially reflecting a more general sensitivity to purpose in the social and natural worlds.  相似文献

This study investigates associations between trajectories of children's vocabulary development and subsequent behavioral and emotional difficulties via two potential mediating mechanisms; literacy and peer problems. Nationally representative data from 4,983 Australian children were used to examine trajectories of receptive vocabulary (4–5, 6–7, and 8–9 years) and hyperactivity-inattention, conduct problems and emotional symptoms (8–9, 10–11, 12–13, 14–15 years), and literacy and peer problems (8–9 years). Lower growth in vocabulary was related to trajectories of hyperactivity-inattention, conduct problems, and emotional symptoms. Literacy was a key mediator explaining these associations. Results were consistent for children below the 50th percentile for vocabulary at 4–5 years compared to the full sample. These findings suggest that early literacy-based interventions may alleviate declining academic, emotional and behavioral functioning in adolescence.  相似文献

The ability to evaluate “sins of omission”—true but pragmatically misleading, underinformative pedagogy—is critical for learning. This study reveals a developmental change in children's evaluation of underinformative teachers and investigates the nature of their limitations. Participants rated a fully informative teacher and an underinformative teacher in two different orders. Six‐ and 7‐year‐olds (N = 28) successfully distinguished the teachers regardless of the order (Experiment 1), whereas 4‐ and 5‐year‐olds (N = 82) succeeded only when the fully informative teacher came first (Experiments 2 and 3). After seeing both teachers, 4‐year‐olds (N = 32) successfully preferred the fully informative teacher (Experiment 4). These results are discussed in light of developmental work in pragmatic implicature, suggesting that young children might struggle with spontaneously generating relevant alternatives for evaluating underinformative pedagogy.  相似文献

How does developing attentional control operate within visual short‐term memory (VSTM)? Seven‐year‐olds, 11‐year‐olds, and adults (total n = 205) were asked to report whether probe items were part of preceding visual arrays. In Experiment 1, central or peripheral cues oriented attention to the location of to‐be‐probed items either prior to encoding or during maintenance. Cues improved memory regardless of their position, but younger children benefited less from cues presented during maintenance, and these benefits related to VSTM span over and above basic memory in uncued trials. In Experiment 2, cues of low validity eliminated benefits, suggesting that even the youngest children use cues voluntarily, rather than automatically. These findings elucidate the close coupling between developing visuospatial attentional control and VSTM.  相似文献

The present research examined the influence of peer characteristics on children's reactions to upward social comparisons. In Experiment 1, one hundred twenty‐six 5‐, 8‐, and 10‐year‐olds were told that they were outperformed by an expert or novice peer. Older children reported higher self‐evaluations after comparisons with an expert rather than a novice, whereas 5‐year‐olds reported high self‐evaluations broadly. In Experiment 2, ninety‐eight 5‐ to 6‐year‐olds and 9‐ to 10‐year‐olds were told that the peer possessed a positive or negative trait that was task relevant (i.e., intelligence) or task irrelevant (i.e., athleticism). Older children reported higher self‐evaluations after hearing about positive rather than negative traits, irrespective of relevance. Younger children reported high self‐evaluations indiscriminately. Results inform the understanding of social comparison development in childhood.  相似文献

Western preschool children often assign ownership based on first possession and some theorists have proposed that this judgment might be an early emerging, innate bias. Five‐ to 9‐year‐olds (n = 112) from a small‐scale group in Kenya (Kikuyu) watched videotaped interactions of two women passing an object. The object's starting position and the women's gestures were varied. Use of the first possession heuristic increased with age, and 8‐ to 9‐year‐olds performed similarly to German 5‐year‐olds (= 24). Starting position and gestures had no effect. A control study confirmed that 5‐year‐old Kikuyus (= 20) understood the video material. The findings reveal that the first possession heuristic follows different developmental trajectories cross‐culturally and stress the role of children's sociocultural environment.  相似文献

Children often “overimitate,” comprehensively copying others' actions despite manifest perceptual cues to their causal ineffectuality. The inflexibility of this behavior renders its adaptive significance difficult to apprehend. This study explored the boundaries of overimitation in 3‐ to 6‐year‐old children of three distinct cultures: Westernized, urban Australians (N = 64 in Experiment 1; N = 19 in Experiment 2) and remote communities of South African Bushmen (N = 64) and Australian Aborigines (N = 19). Children overimitated at high frequency in all communities and generalized what they had learned about techniques and object affordances from one object to another. Overimitation thus provides a powerful means of acquiring and flexibly deploying cultural knowledge. The potency of such social learning was also documented compared to opportunities for exploration and practice.  相似文献

This study investigated the benefits of self‐distancing (i.e., taking an outsider's view of one's own situation) on young children's perseverance. Four‐ and 6‐year‐old children (N = 180) were asked to complete a repetitive task for 10 min while having the option to take breaks by playing an extremely attractive video game. Six‐year‐olds persevered longer than 4‐year‐olds. Nonetheless, across both ages, children who impersonated an exemplar other—in this case a character, such as Batman—spent the most time working, followed by children who took a third‐person perspective on the self, or finally, a first‐person perspective. Alternative explanations, implications, and future research directions are discussed.  相似文献

The mechanical transmission of motion, which is observable in gears’ turning direction (TD) and turning speed (TS) can be understood as part of the core concept “force and motion”. Previous studies have suggested that most children before the age of nine have naïve concepts of gears’ TD and TS. However, these studies relied on children's explanation data and might have therefore underestimated young children's potential. Moreover, these studies did not examine whether preschoolers can overcome their naïve concepts through teaching. Recently, educators have proposed guided play as an educational approach that combines children's play with teacher guidance in a purposefully designed environment. We conducted two subsequent studies. In Study 1, we investigated the children's (naïve) concepts of gears’ TD and TS with a cross‐sectional approach using a nonverbal test procedure. This study comprised 248 children aged 5–10 years and 73 adults. The results showed that the proportion of children with adequate concepts increased with age. More specifically, 7‐ to 8‐year‐olds differed significantly from 5‐ to 6‐year‐olds, indicating a developmental shift around this age. However, naïve concepts of TS were more persistent with age than naïve concepts of TD. Altogether, the results indicated the potential to foster 5‐ to 6‐year‐olds’ concepts of both TD and TS in an intervention. Thus, in Study 2, we developed and tested a guided play intervention to foster 5‐ to 6‐year‐old children's concepts of TD and TS. We conducted a prepost‐intervention design with a guided play group (n = 19) and a free play group (n = 21). The results suggested stronger learning gains in the guided play group (dTD = 0.337, dTS = 0.758) than in the free play group (dTD = 0.224, dTS = 0.158).  相似文献
