Previous work has shown that toddlers readily encode each noun in the sentence as a distinct argument of the verb. However, languages allow multiple mappings between form and meaning that do not fit this canonical format. Two experiments examined French 28‐month‐olds' interpretation of right‐dislocated sentences (nouni‐verb, nouni) where the presence of clear, language‐specific cues should block such a canonical mapping. Toddlers (N = 96) interpreted novel verbs embedded in these sentences as transitive, disregarding prosodic cues to dislocation (Experiment 1) but correctly interpreted right‐dislocated sentences containing well‐known verbs (Experiment 2). These results suggest that toddlers can integrate multiple cues in ideal conditions, but default to canonical surface‐to‐meaning mapping when extracting structural information about novel verbs in semantically impoverished conditions.  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

Two experiments investigated the development of metacognitive monitoring and control, and conditions under which children engage these processes. In Experiment 1, 5‐year‐olds (N = 30) and 7‐year‐olds (N = 30), unlike adults (N = 30), showed little evidence of either monitoring or control. In Experiment 2, 5‐year‐olds (N = 90) were given performance feedback (aimed at improving monitoring), instruction to follow a particular strategy (aimed at improving control), or both. Across conditions, feedback improved children's monitoring, and instruction improved both monitoring and control. Thus, children's poor metacognitive performance likely reflects a difficulty engaging the component processes spontaneously rather than a lack of metacognitive ability. These findings also suggest that the component processes are distinct, with both undergoing protracted development.  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

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

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

Two experiments examined 4‐ and 5‐year‐olds' use of vocal affect to learn new words. In Experiment 1 (= 48), children were presented with two unfamiliar objects, first in their original state and then in an altered state (broken or enhanced). An instruction produced with negative, neutral, or positive affect, directed children to find the referent of a novel word. During the novel noun, eye gaze measures indicated that both 4‐ and 5‐year‐olds were more likely to consider an object congruent with vocal affect cues. In Experiment 2, 5‐year‐olds (= 15) were asked to extend and generalize their initial mapping to new exemplars. Here, 5‐year‐olds generalized these newly mapped labels but only when presented with negative vocal affect.  相似文献

It is widely believed that exploration is a mechanism for young children's learning. The present investigation examines preschoolers’ beliefs about how learning occurs. We asked 3‐ to 5‐year‐olds to articulate how characters in a set of stories learned about a new toy. Younger preschoolers were more likely to overemphasize the role of characters’ actions in learning than older children were (Experiment 1, N = 53). Overall performance improved when the stories explicitly stated that characters were originally ignorant and clarified the characters’ actions, but general developmental trends remained (Experiment 2, N = 48). These data suggest that explicit metacognitive understanding of the relation between actions and learning is developing during the preschool years, which might have implications for how children learn from exploration.  相似文献

In accumulating knowledge, direct modes of learning are complemented by productive processes, including self‐generation based on integration of separate episodes. Effects of the number of potentially relevant episodes on integration were examined in 4‐ to 8‐year‐olds (= 121; racially/ethnically heterogeneous sample, English speakers, from large metropolitan area). Information was presented along with unrelated or related episodes; the latter challenged children to identify the relevant subset of episodes for integration. In Experiment 1, 4‐ and 6‐year‐olds integrated in the unrelated context. Six‐year‐olds also succeeded in the related context in forced‐choice testing. In Experiment 2, 8‐year‐olds succeeded in open‐ended and forced‐choice testing. Results illustrate a developmental progression in productive extension of knowledge due in part to age‐related increases in identification of relevant information.  相似文献

Executive functions enable flexible thinking, something young children are notoriously bad at. For instance, in the dimensional change card sort (DCCS) task, 3‐year‐olds can sort cards by one dimension (shape), but continue to sort by this dimension when asked to switch (to color). This study tests a prediction of a dynamic neural field model that prior experience with the postswitch dimension can enhance 3‐year‐olds' performance in the DCCS. In Experiment 1A, a matching game was used to preexpose 3‐year‐olds (= 36) to color. This facilitated switching from sorting by shape to color. In 3 , 3‐year‐olds (n = 18) were preexposed to shape. This did not facilitate switching from sorting by color to shape. The model was used to explain this asymmetry.  相似文献

This study investigated the nature of infants’ difficulty understanding references to hidden inaccessible objects. Twelve‐month‐old infants (N = 32) responded to the mention of objects by looking at, pointing at, or approaching them when the referents were visible or accessible, but not when they were hidden and inaccessible (Experiment I). Twelve‐month‐olds (N = 16) responded robustly when a container with the hidden referent was moved from a previously inaccessible position to an accessible position before the request, but failed to respond when the reverse occurred (Experiment II). This suggests that infants might be able to track the hidden object's dislocations and update its accessibility as it changes. Knowing the hidden object is currently inaccessible inhibits their responding. Older, 16‐month‐old (N = 17) infants’ performance was not affected by object accessibility.  相似文献

Numerous studies have investigated children's abilities to attribute mental states, but few have examined their ability to recruit these abilities in social interactions. Here, 6‐year‐olds (N = 104) were tested on whether they can use first‐ and second‐order false‐belief understanding to coordinate with peers. Children adjusted their decisions in a coordination game in response to either their partner's erroneous belief or their partner's erroneous belief about their own belief—a result that contrasts with previous findings on the use of higher order “theory of mind” (TOM) reasoning at this age. Six‐year‐olds are thus able to use their higher order TOM capacities for peer coordination, which marks an important achievement in becoming competent social collaborators.  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

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

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

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

Preschoolers have limited capacity to use past experiences to prepare for the future. Two experiments sought to further understand these limitations. Experiment 1 (N = 42) showed that 3- to 4-year olds’ difficulty performing anticipated future actions was constrained by their memory for relevant past actions, especially those including temporal information. Experiment 2 (N = 94) sought to determine whether preschoolers fail to see that past experiences can inform future-oriented actions. When the connection between the past and future was experimentally heightened, future thinking accuracy improved, but only if preschoolers remembered past experiences. The results indicate that past recall is a prerequisite for future thinking but failure to bridge past and future further accounts for observed limitations in future thinking in early childhood.  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 how children negotiate social norms with peers. In Study 1, 48 pairs of 3‐ and 5‐year‐olds (N = 96) and in Study 2, 48 pairs of 5‐ and 7‐year‐olds (N = 96) were presented with sorting tasks with conflicting instructions (one child by color, the other by shape) or identical instructions. Three‐year‐olds differed from older children: They were less selective for the contexts in which they enforced norms, and they (as well as the older children to a lesser extent) used grammatical constructions objectifying the norms (“It works like this” rather than “You must do it like this”). These results suggested that children's understanding of social norms becomes more flexible during the preschool years.  相似文献

During communication, conversational partners should offer as much information as is required and relevant. For instance, the statement “Some Xs Y” is infelicitous if one knows that all Xs Y. Do children understand the link between speaker knowledge and utterance strength? In Experiment 1, 5‐year‐olds (= 32) but not 4‐year‐olds (= 32) reliably connected statements of different logical strength (e.g., “The girl colored all/some of the star”) to observers who were fully or partially informed. Four‐year‐olds’ performance improved when observer knowledge could be assessed more easily (Experiment 2a, = 25) but remained the same in a nonlinguistic version of Experiment 1 that preserved the epistemic requirements of the original study (Experiment 2b, = 26). These findings have implications for the development of early communicative abilities.  相似文献
