So how do children stop making such errors? In this study, we test the assumption that children's ability to recover from error is related to their developing sensitivity to longer-range dependencies. We use a pre-registered corpus analysis to explore the predictive value of different cues with regards to children's verb-marking errors and observe a developmental pattern consistent with this account. We look at context-independent cues (the identity of the specific verb being used) and at the relative value of context-dependent cues (the identity of the specific subject+verb sequence being used). We find that the only consistent effect across a group of 2- to 3-year-olds and a group of 3- to 4-year-olds is the relative frequency of unmarked forms of <i>specific</i> subject+verb sequences being used. The relative frequency of unmarked forms of the verb alone is predictive only in the younger age group. This is consistent with an account in which children recover from making errors by becoming progressively more sensitive to context, at first the immediately preceding lexical contexts (e.g., the subject that precedes the verb) and eventually more distant grammatical markers (e.g., the fronted auxiliary that precedes the subject in questions).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Research Highlights</h3>\u0000 \u0000 <div>\u0000 <ul>\u0000 \u0000 <li>We provide a corpus analysis investigating input effects on young children's verb-marking errors (e.g., Mummy go) across development (between 2 and 4 years of age).</li>\u0000 \u0000 <li>We find evidence that these apparent errors of omission are in fact input-driven errors of commission that persist into the third year of life.</li>\u0000 \u0000 <li>We compare the relative effect on error rates of context-independent (e.g., verb) and context-dependent (e.g., subject+verb sequence) cues across developmental time.</li>\u0000 \u0000 <li>Our findings support the proposal that children recover from making verb-marking errors by becoming progressively more sensitive to preceding context.</li>\u0000 </ul>\u0000 </div>\u0000 </section>\u0000 </div>","PeriodicalId":48392,"journal":{"name":"Developmental Science","volume":"27 6","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/desc.13543","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141499294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Second, consistent with research on children's stereotypes about gender and math (e.g., associating boys with math competence), children might prefer to learn from exemplars who match their stereotypes about who is good at math (H2). We tested these hypotheses with children in middle school (<i>N</i> = 166), a time of development in which stereotypes are well-engrained, but before gender differences in math achievement appear.

Questions remain regarding the neural and cognitive processes differentiating children who pass versus fail behavioral false-belief tasks and the extent to which there is continuity versus change in the ToM neural network. To address these questions, we analyzed event-related spectral power in the electroencephalogram (EEG) to investigate how preschoolers’ neural activity during passive viewing of false-belief scenarios related to their explicit behavioral ToM performance. We found that neural activity during passive viewing of false-belief events (6–9 Hz EEG ‘alpha’ suppression in right temporoparietal [RTP] electrodes) strongly related to children's explicit ToM. However, children's RTP alpha suppression differed depending on their explicit behavioral ToM performance: Children who did better on a broad battery of standard ToM tasks and who passed explicit behavioral false-belief tasks showed greater RTP alpha suppression when the character's belief first became false (during the ‘location-change’ event); whereas children who did worse on the ToM battery and who failed explicit behavioral false-belief tasks showed greater RTP alpha suppression only later when they could evaluate the character's behavior in the context of prior events (during the ‘active-search’ event).

By capturing variability in how children respond to daily fluctuations in their environment, we can contribute to the early prediction of mental health problems and improve access to early intervention services for children and families who need them most.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Research Highlights</h3>\u0000 \u0000 <div>\u0000 <ul>\u0000 \u0000 <li>Children differ in how strongly their behavior depends on psychosocial factors including parent praise, child mood, child sleep, and parent stress.</li>\u0000 \u0000 <li>Children who are more sensitive to their parents’ praise at age 3 have fewer internalizing and externalizing problems at age 5–7 years.</li>\u0000 \u0000 <li>Child sensitivity to mood also predicts fewer internalizing and externalizing problems.</li>\u0000 </ul>\u0000 </div>\u0000 </section>\u0000 </div>","PeriodicalId":48392,"journal":{"name":"Developmental Science","volume":"27 5","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/desc.13531","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141307185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we studied motor skill learning in children, adolescents, and young adults to test the prediction that differences in the maturation of different learning mechanisms lead to distinct temporal patterns of motor learning during practice and overnight. We found that overall learning did not differ between children, adolescents, and young adults. However, we demonstrate that adult-like skill learning is characterized by rapid and large improvements in motor performance during practice (i.e., online) that are susceptible to forgetting and decay over time (i.e., offline). On the other hand, child-like learning exhibits slower and less pronounced improvements in performance during practice, but these improvements are robust against forgetting and lead to gains in performance overnight without further practice. The different temporal dynamics of motor skill learning suggest an engagement of distinct learning mechanisms in the human CNS during development. In conclusion, adult-like skill learning mechanisms favor online improvements in motor performance whereas child-like learning mechanisms favors offline behavioral gains.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Research Highlights</h3>\u0000 \u0000 <div>\u0000 <ul>\u0000 \u0000 <li>Many essential motor skills, like walking, talking, and writing, are acquired during childhood, and it is colloquially thought that children learn better than adults.</li>\u0000 \u0000 <li>We investigated dynamics of motor skill learning in children, adolescents, and young adults.</li>\u0000 \u0000 <li>Adults displayed substantial improvements during practice that was susceptible to forgetting over time.
