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

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

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

Realizing Relevance: The Influence of Domain‐Specific Information on Generation of New Knowledge Through Integration in 4‐ to 8‐Year‐Old Children 下载免费PDF全文
下载免费PDF全文 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 (N = 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

The study investigated if 2.5‐year‐olds are susceptible to suspense and express tension when others' false expectations are about to be disappointed. In two experiments (N = 32 each), children showed more tension when a protagonist approached a box with a false belief about its content than when she was ignorant. In Experiment 2, children also expressed more tension when the protagonist's belief was false than when it was true. The findings reveal that toddlers affectively anticipate the “rude awakening” of an agent who is about to discover unexpected reality. They thus not only understand false beliefs per se but also grasp the affective implications of being mistaken. The results are discussed with recourse to current theories about early understanding of false beliefs. 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

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

Three experiments investigate how self‐generated explanation influences children's causal learning. Five‐year‐olds (N = 114) observed data consistent with two hypotheses and were prompted to explain or to report each observation. In Study 1, when making novel generalizations, explainers were more likely to favor the hypothesis that accounted for more observations. In Study 2, explainers favored a hypothesis that was consistent with prior knowledge. Study 3 pitted a hypothesis that accounted for more observations against a hypothesis consistent with prior knowledge. Explainers were more likely to base generalizations on prior knowledge. Findings suggest that attempts to explain drive children to evaluate hypotheses using features of “good” explanations, or those supporting generalizations with broad scope, as informed by children's prior knowledge and observations. 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 (N = 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, N = 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

The present experiments tested bilingual infants' developmental narrowing for the interpretation of sounds that form words. These studies addressed how language specialization proceeds when the environment provides varied and divergent input. Experiment 1 (N = 32) demonstrated that bilingual 14‐ and 19‐month‐olds learned a pair of object labels consisting of the same syllable produced with distinct pitch contours (rising and falling). Infants' native languages did not use pitch contour to differentiate words. In Experiment 2 (N = 16), 22‐month‐old bilinguals failed to learn the labels. These results conflict with the developmental trajectory of monolinguals, who fail to learn pitch contour contrasts as labels at 17–19 months (Hay, Graf Estes, Wang, & Saffran, 2015). Bilingual infants exhibited a prolonged period of flexibility in their interpretation of potential word forms. 相似文献

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

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

Three experiments (N = 130) used a minimal group manipulation to show that just perceived membership in a social group boosts young children's motivation for and learning from group‐relevant tasks. In Experiment 1, 4‐year‐old children assigned to a minimal “puzzles group” persisted longer on a challenging puzzle than children identified as the “puzzles child” or children in a control condition. Experiment 2 showed that this boost in motivation occurred only when the group was associated with the task. In Experiment 3, children assigned to a minimal group associated with word learning learned more words than children assigned an analogous individual identity. The studies demonstrate that fostering shared motivations may be a powerful means by which to shape young children's academic outcomes. 相似文献

Three studies investigated 3‐year‐old children's ability to determine a speaker's communicative intent when the speaker's overt utterance related to that intent only indirectly. Studies 1 and 2 examined children's comprehension of indirectly stated requests (e.g., “I find Xs good” can imply, in context, a request for X; N = 32). Study 3 investigated 3‐ and 4‐year‐old children's and adults' (N = 52) comprehension of the implications of a speaker responding to an offer by mentioning an action's fulfilled or unfulfilled precondition (e.g., responding to an offer of cereal by stating that we have no milk implies rejection of the cereal). In all studies, 3‐year‐old children were able to make the relevance inference necessary to integrate utterances meaningfully into the ongoing context. 相似文献

Similes require two different pragmatic skills: appreciating the intended similarity and deriving a scalar implicature (e.g., “Lucy is like a parrot” normally implies that Lucy is not a parrot), but previous studies overlooked this second skill. In Experiment 1, preschoolers (N = 48; ages 3–5) understood “X is like a Y” as an expression of similarity. In Experiment 2 (N = 99; ages 3–6, 13) and Experiment 3 (N = 201; ages 3–5 and adults), participants received metaphors (“Lucy is a parrot”) or similes (“Lucy is like a parrot”) as clues to select one of three images (a parrot, a girl or a parrot-looking girl). An early developmental trend revealed that 3-year-olds started deriving the implicature “X is not a Y,” whereas 5-year-olds performed like adults. 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

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

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
