One of the core functions of explanation is to support prediction and generalization. However, some explanations license a broader range of predictions than others. For instance, an explanation about biology could be presented as applying to a specific case (e.g., “this bear”) or more generally across “all animals.” The current study investigated how 5‐ to 7‐year‐olds (N = 36), 11‐ to 13‐year‐olds (N = 34), and adults (N = 79) evaluate explanations at varying levels of generality in biology and physics. Findings revealed that even the youngest children preferred general explanations in biology. However, only older children and adults preferred explanation generality in physics. Findings are discussed in light of differences in our intuitions about biological and physical principles. 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 (N = 80), 8‐ to 10‐year‐olds (N = 72), and adults (N = 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

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

Power differences are observed in children's early relationships, yet little is known about how children conceptualize social power. Study 1 recruited adults (n = 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

This study examined the effect of a “ghost” demonstration on toddlers’ imitation. In the ghost condition, virtual pieces moved to make a fish or boat puzzle. Fifty‐two 2.5‐ and 3‐year‐olds were tested on a touchscreen (no transfer) or with 3D pieces (transfer); children tested with 3D pieces scored above a no demonstration baseline, but children tested on the touchscreen did not. Practice on the touchscreen (n = 23) by 2.5‐ and 3‐year‐olds prior to the ghost demonstration did not improve performance. Finally, children who learned the puzzle task via a social demonstration and were tested on the touchscreen (n = 26) performed better than the ghost conditions. Taken together, these studies demonstrate that social demonstrations enhance learning from novel touchscreen tools during early childhood. 相似文献

Adults implicitly judge people from certain social backgrounds as more “American” than others. This study tests the development of children's reasoning about nationality and social categories. Children across cultures (White and Korean American children in the United States, Korean children in South Korea) judged the nationality of individuals varying in race and language. Across cultures, 5‐ to 6‐year‐old children (N = 100) categorized English speakers as “American” and Korean speakers as “Korean” regardless of race, suggesting that young children prioritize language over race when thinking about nationality. Nine‐ and 10‐year‐olds (N = 181) attended to language and race and their nationality judgments varied across cultures. These results suggest that associations between nationality and social category membership emerge early in life and are shaped by cultural context. 相似文献

Getting to No: Pragmatic and Semantic Factors in Two‐ and Three‐Year‐Olds' Understanding of Negation 下载免费PDF全文
下载免费PDF全文 Although infants say “no” early, older children have difficulty understanding its truth‐functional meaning. Two experiments investigate whether this difficulty stems from the infelicity of negative sentences out of the blue. In Experiment 1, given supportive discourse, 3‐year‐olds (N = 16) understood both affirmative and negative sentences. However, with sentence types randomized, 2‐year‐olds (N = 28) still failed. In Experiment 2, affirmative and negative sentences were blocked. Two‐year‐olds (N = 28) now succeeded, but only when affirmatives were presented first. Thus, although discourse felicity seems the primary bottleneck for 3‐year‐olds' understanding of negation, 2‐year‐olds struggle with its semantic processing. Contrary to accounts where negatives are understood via affirmatives, both sentence types were processed equally quickly, suggesting previously reported asymmetries are due to pragmatic accommodation, not semantic processing. 相似文献

Four studies (N = 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

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

The Development of Selective Copying: Children's Learning From an Expert Versus Their Mother 下载免费PDF全文

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

“I Know You Don't Know I Know…” Children Use Second‐Order False‐Belief Reasoning for Peer Coordination 下载免费PDF全文
下载免费PDF全文 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

Parochial Compliance: Young Children's Biased Consideration of Authorities’ Preferences Regarding Intergroup Interactions 下载免费PDF全文
下载免费PDF全文 Prosocial behavior is arguably influenced by an interaction between intrinsic dispositions (e.g., group bias) and extrinsic factors (e.g., institutional regulations). The current study investigated this interaction developmentally. Preschoolers (3‐ to 4‐year‐olds) and kindergarteners (5‐ to 6‐year‐olds; N = 111) participated in a resource distribution task in which they had to consider both the recipients’ group membership (minimal color‐based groups), and their own teachers’ preferences regarding how to distribute (give “all” or “none”). The results revealed that only kindergarteners were influenced by the experimental factors and differently across genders. Specifically, when the recommendation was to give “none,” girls followed it indiscriminately toward in‐ and out‐group recipients, but boys did so only toward out‐group recipients. Thus, boys exploited an authority's legitimization to act antisocially, according to a parochial bias. 相似文献

Can children learn to select the right strategy for a given problem? In one experiment, 9‐ to 10‐year‐olds (N = 50), 11‐ to 12‐year‐olds (N = 50), and adults (N = 50) made probabilistic inferences. Participants encountered environments favoring either an information‐intensive strategy that integrates all available information or an information‐frugal strategy that relies only on the most valid pieces of information. Nine‐ to 10‐year‐olds but not older children or adults had more difficulties learning to select an information‐frugal strategy than an information‐intensive strategy. This counterintuitive finding is explained by children’s less developed ability to selectively attend to relevant information, an ability that seems to develop during late childhood. The results suggest that whether a strategy can be considered “easy” depends on the development of specific cognitive abilities. 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

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

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

Place value notation is essential to mathematics learning. This study examined young children's (4‐ to 6‐year‐olds, N = 172) understanding of place value prior to explicit schooling by asking them write spoken numbers (e.g., “six hundred and forty‐two”). Children's attempts often consisted of “expansions” in which the proper digits were written in order but with 0s or other insertions marking place (e.g., “600402” or “610042”). This partial knowledge increased with age. Gender differences were also observed with older boys more likely than older girls to produce the conventional form (e.g., 642). Potential experiences contributing to expanded number writing and the observed gender differences are discussed. 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

Two experiments examined 4‐ and 5‐year‐olds' use of vocal affect to learn new words. In Experiment 1 (n = 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 (n = 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

If You're Happy and You Know It: Positive Moods Reduce Age‐Related Differences in False Memory 下载免费PDF全文
下载免费PDF全文 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
