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

Executive function (EF) plays a foundational role in development. A brain-based model of EF development is probed for the experiences that strengthen EF in the dimensional change card sort task in which children sort cards by one rule and then are asked to switch to another. Three-year-olds perseverate on the first rule, failing the task, whereas 4-year-olds pass. Three predictions of the model are tested to help 3-year-olds (N = 54) pass. Experiment 1 shows that experience with shapes and the label “shape” helps children. Experiment 2 shows that experience with colors—without a label—helps children. Experiment 3 shows that experience with colors induces dimensional attention. The implications of this work for early intervention are discussed. 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

Strategic collaboration according to the law of comparative advantage involves dividing tasks based on the relative capabilities of group members. Three experiments (N = 405, primarily White and Asian, 45% female, collected 2016–2019 in Canada) examined how this strategy develops in children when dividing cognitive labor. Children divided questions about numbers between two partners. By 7 years, children allocated difficult questions to the skilled partner (Experiment 1, d = 1.42; Experiment 2, d = 0.87). However, younger children demonstrated a self-serving bias, choosing the easiest questions for themselves. Only when engaging in a third-party collaborative task did 5-year-olds assign harder questions to the more skilled individual (Experiment 3, d = 0.55). These findings demonstrate early understanding of strategic collaboration subject to a self-serving bias. 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

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

This study investigated whether seeing iconic gestures depicting verb referents promotes two types of generalization. We taught 3- to 4-year-olds novel locomotion verbs. Children who saw iconic manner gestures during training generalized more verbs to novel events (first-order generalization) than children who saw interactive gestures (Experiment 1, N = 48; Experiment 2, N = 48) and path-tracing gestures (Experiment 3, N = 48). Furthermore, immediately (Experiments 1 and 3) and after 1 week (Experiment 2), the iconic manner gesture group outperformed the control groups in subsequent generalization trials with different novel verbs (second-order generalization), although all groups saw interactive gestures. Thus, seeing iconic gestures that depict verb referents helps children (a) generalize individual verb meanings to novel events and (b) learn more verbs from the same subcategory. 相似文献

Three experiments were conducted to study on a more fine-grained level how processing a picture facilitates learning from text. In Experiment 1 (N = 85), results from a drawing task revealed that the global spatial structure of a pulley system picture was extracted even from its brief inspection (for 600 ms, 2 s). In Experiment 2 (N = 105), students who initially inspected the pulley system picture (for 600 ms, 2 s, or self-paced) had better comprehension of the system's functions and made more eye movements in line with the system's global spatial structure when listening to text than students who listened to text only. In Experiment 3 (N = 39), students who first saw the picture (for 2 s) processed written text of the pulley system's spatial structure more efficiently than students who read text only. Results suggest that global spatial information extracted from the picture was used as a mental scaffold to facilitate mental model construction. 相似文献

This study examined whether executive functions impact how flexibly children represent task context in performing repeated sequential actions. Japanese children in Experiments 1 (N = 52; 3–6 years) and 2 (N = 50, 4–6 years) performed sequential actions repeatedly; one group received reminders. Experiment 1 indicated that reminders promote flexible changes in contextual representations. Experiment 2 observed such effects in younger children and showed executive functions were associated with the flexible representation of task context. Reminders did not perfectly compensate for the role of executive functions but wiped out individual differences in executive functions that contribute to children’s acquisition of routines. Therefore, setting goals before context-dependent actions is necessary, but not sufficient, to modulate contextual representations in routines. 相似文献

Explicit Theory of Mind Is Even More Unified Than Previously Assumed: Belief Ascription and Understanding Aspectuality Emerge Together in Development 下载免费PDF全文
下载免费PDF全文 Existing evidence suggests that children, when they first pass standard theory‐of‐mind tasks, still fail to understand the essential aspectuality of beliefs and other propositional attitudes: such attitudes refer to objects only under specific aspects. Oedipus, for example, believes Yocaste (his mother) is beautiful, but this does not imply that he believes his mother is beautiful. In three experiments, 3‐ to 6‐year‐olds' (N = 119) understanding of aspectuality was tested with a novel, radically simplified task. In contrast to all previous findings, this task was as difficult as and highly correlated with a standard false belief task. This suggests that a conceptual capacity more unified than previously assumed emerges around ages 4–5, a full‐fledged metarepresentational scheme of propositional attitudes. 相似文献

Social working memory (WM) has distinct neural substrates from canonical cognitive WM (e.g., color). However, no study, to the best of our knowledge, has yet explored how social WM develops. The current study explored the development of social WM capacity and its relation to theory of mind (ToM). Experiment 1 had sixty-four 3- to 6-year-olds memorize 1–5 biological motion stimuli, the processing of which is considered a hallmark of social cognition. The social WM capacity steadily increased between 3- and 6-year-olds, with the increase between 4 and 5 years being sharp. Furthermore, social WM capacity positively predicted preschoolers' ToM scores, while nonsocial WM capacity did not; this positive correlation was particularly strong among 4-year-olds (Experiment 2, N = 144). 相似文献

Children often judge that strange and improbable events are impossible, but the mechanisms behind their reasoning remain unclear. This article (N = 250) provides evidence that young children use a similarity heuristic that compares potential events to similar known events to determine whether events are possible. Experiment 1 shows that 5- to 6-year-olds who hear about improbable events go on to judge that similar improbable events can happen. Experiment 2 shows that 5- to 6-year-olds more often affirm that improbable events can happen if told about related improbable events than if told about unrelated ones. Finally, Experiment 3 shows that 5- to 6-year-olds affirm the possibility of improbable events related to known events, but deny that related impossible events can happen. 相似文献

Gender-nonconforming (GN) children are often perceived less positively, which may harm their well-being. We examined the development of such perceptions and an intervention to modify them. Chinese children’s appraisals were assessed using multiple measures (verbal responses, sharing, and rank order task) after viewing vignettes of gender-conforming (GC) and GN hypothetical peers. In Study 1, children (N = 210; 4-, 5-, 8-, and 9-year-olds) were less positive toward GN than GC peers, especially if they were older or if the peers were boys. In Study 2 (N = 211, 8- and 9-year-olds), showing children exemplars of GN peers who displayed positive and GC characteristics subsequently reduced bias against gender nonconformity. These findings inform strategies aimed at reducing bias against gender nonconformity. 相似文献

In higher education, there are calls to incorporate active learning experiences that place the student at the center of learning, rather than encouraging students to be passive listeners. For students to have a deeper and more meaningful learning experience, educators can use an active learning approach. This approach attempts to engage students at higher levels of thinking so that they are more interested in, better engaged with, and understand the course material better. The aim of this study was to investigate students’ perceptions of Plickers and crossword puzzles as low‐cost pedagogical tools to foster active learning in an undergraduate course in food science and technology. A mixed‐method survey consisting of a 5‐point Likert scale and open‐ended qualitative questions was administered via Blackboard to elicit student responses. A total of 121 students were enrolled for the course and 70.2% (n = 85) completed the survey. Plickers were found to be easy to use (mean = 4.66), provided opportunities to answer to formative questions anonymously (mean = 4.60), and helped increase participation in class (mean 4.05). The majority of students felt that crossword puzzles required them to think critically (mean = 4.53) and provided them with the opportunity to assess how well they understood the course content (mean = 4.45). Moreover, a statistically positive relationship was found between student collaborative learning and crossword puzzle implementation scores (r = .506, p < .01). The findings demonstrated that when implemented effectively, Plickers and crossword puzzles contributed to greater enhanced student engagement. These pedagogical tools can be applied as formative assessment instruments and offer a low‐cost alternative to the limitations encapsulated by didactic pedagogy. 相似文献

We explored the ability of children to adapt their communication to the needs of their communication partner. Monolingual and bilingual 3-year-old children (N = 110) observed two puppets looking for puzzle pieces. One puppet showed its appreciation of the children's help, the other puppet wanted to solve the puzzle on its own. The children's communicative acts were coded in terms of level of ostension (how obviously they indicated the hiding place of the puzzle piece) and level of information (how clearly they indicated the location). Monolinguals and bilinguals were equally helpful and informative. In contrast, only bilingual children adapted their level of ostension selectively between the two puppets. These findings point to the greater skills of bilinguals to adapt their communication accordingly. 相似文献

Children need to learn to persist through challenges, yet adults sometimes step in to solve problems for them. Here, we looked at how adult taking over related to children’s persistence. In an observational study (N = 34, ages 4–8), we found that parents who took over more often during a challenging puzzle task rated their children as dispositionally less persistent. To establish whether taking over can cause reduced persistence, we ran two preregistered experiments (N = 150, ages 4–5). Children assigned to a taking over condition persisted less on a subsequent task compared to those in a teaching or a baseline condition. Reframing the context did not ameliorate the negative impact of taking over. The results suggest that taking over impairs children’s persistence. 相似文献

The papers presented at the 2004 Academy meetings can be thought of as pieces from jigsaw puzzles. While the employment of this metaphor over the years has been useful, we may be ready for a new image, one that is both more accurate and inspiring. We can picture ourselves working at different locations along a river bank. Some of us work upstream, near the headwaters, at the molecular and genetic level. Others work on anatomy, physiology, culture, psychological well-being, ethics, and even spirituality—all different places along the shore as we move down the river toward the broad and deep waters by the bay. But no matter what our location, we all work on water in one form or another. This forces us to come to grips with our interdependence as researchers and with far more complex notions of causation that have been popular heretofore. The riverbank metaphor promises a kind of cooperation, unity, and mutual appreciation that cannot be gained when we come to interdisciplinary meetings carrying our independently produced and prized puzzle pieces. 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

We examined the quality of 4‐ to 6‐year‐olds' production of narratives from picture sequences. Children (N = 81) first viewed a narrative picture sequence and then completed the narrative production task in each of two orders: either before or after answering a set of questions about the core elements of the story. Narratives elicited after questions were more coherent than those produced before the questions. In contrast, task order did not influence the cohesion of narratives nor the accuracy of responses to questions. An independent measure of memory was related to the gains in narrative coherence after answering questions. The results are discussed in relation to the role of questions as a guide to the structural elements of a narrative and a scaffold for understanding. 相似文献

In two experiments, eye tracking was used to investigate whether learners construct a mental representation during learning that integrates information from text and pictures. The experimental groups received inconsistent text-picture information on one or two pages of the learning materials. The control groups received only consistent text-picture information. It was expected that learners of the experimental groups should have difficulties in integrating text-picture information when faced with the inconsistencies. This should be reflected in their gaze behavior. Experiment 1 (N = 51) and Experiment 2 (N = 45) confirmed that assumption for several eye tracking variables. Regarding learning outcomes, only in Experiment 1 worse performance of the experimental group was observed. Furthermore, Experiment 2 revealed that the majority of learners did not remember the inconsistency between text and picture when asked for it after learning. In sum, the results add to our understanding about the cognitive processes underlying multimedia learning. 相似文献
