The sample included 167 adolescents (47% girls) who were assessed at five time points with approximately 1 year between each assessment, beginning in middle adolescence (<i>M</i>_age= 14.07) and ending in the transition to young adulthood (<i>M</i>_age= 18.39). The adolescents reported their perceived attachment with both their mother and father during middle adolescence (Times 1 and 2), their internalizing and externalizing symptoms during late adolescence (Times 3 and 4), and their alcohol use during the transition to young adulthood (Time 5). The results showed that less secure adolescent–father attachment, but not adolescent–mother attachment, was predictive of heightened externalizing and internalizing symptoms. In turn, heightened externalizing symptoms were predictive of heightened alcohol use. Despite the nonsignificant direct association between adolescent–father attachment and alcohol use, less secure adolescent–father attachment was indirectly predictive of greater alcohol use, mediated through heightened externalizing symptoms. The findings highlight the importance of close and trusting father–adolescent relationships in the development of psychopathology and substance use behaviors. The developmental cascade from a less secure adolescent–father attachment to greater externalizing symptoms and heightened substance use, as well as implications for prevention and intervention of young adult substance use, are discussed.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Research Highlights</h3>\u0000 \u0000 <div>\u0000 <ul>\u0000 \u0000 <li>The differential pathways from adolescent–mother and adolescent–father attachment to substance use during the transition to young adulthood are not well known.</li>\u0000 \u0000 <li>Longitudinal data were used to test whether internalizing and externalizing symptoms may mediate the association between adolescent–mother and adolescent–father attachment and substance use.</li>\u0000 \u0000 <li>Less secure adolescent–father attachment predicted heightened internalizing and externalizing symptoms, and less secure adolescent–father attachment predicted greater alcohol use, mediated through heightened externalizing symptoms.</li>\u0000 \u0000 <li>The findings suggest that addressing insecure attachment with fathers during adolescence may reduce unhealthy substance use during the transition to young adulthood.</li>\u0000 </ul>\u0000 </div>\u0000 </section>\u0000 </div>","PeriodicalId":48392,"journal":{"name":"Developmental Science","volume":"27 6","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/desc.13539","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141503879","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}

Cortical thinning is a prominent feature of this development, and some researchers have suggested that differences in cortical thickness may be related to internalizing symptoms, which typically increase during the same period. However, research has yielded inconclusive results. We utilized a new method that estimates the combined effect of individual differences in vertex-wise cortical thickness on internalizing symptoms. This approach allows for many small effects to be distributed across the cortex and avoids the necessity of correcting for multiple tests. Using a sample of 8763 children aged 8.9 to 11.1 from the ABCD study, we decomposed the total variation in caregiver-reported internalizing symptoms into differences in cortical thickness, additive genetics, and shared family environmental factors and unique environmental factors. Our results indicated that individual differences in cortical thickness accounted for less than 0.5% of the variation in internalizing symptoms. In contrast, the analysis revealed a substantial effect of additive genetics and family environmental factors on the different components of internalizing symptoms, ranging from 06% to 48% and from 0% to 34%, respectively.

In the current study, we investigated how behavioral sensitivity at age 3 years predicts mental health in middle childhood. Using a novel repeated measures design, we calculated child sensitivity to multiple psychological and social influences: parent praise, parent stress, child mood, and child sleep. We conceptualized sensitivity as the strength and direction of the relationship between psychosocial influences and child behavior, operationalized as toothbrushing time, at age 3 years. When children were 5–7 years old (<i>n</i> = 60), parents reported on children's internalizing and externalizing problems. Children who were more sensitive to their parents’ praise at age 3 had fewer internalizing (<i>r</i> = −0.37, <i>p</i> = 0.016, <i>p_FDR</i> = 0.042) and externalizing (<i>r</i> = −0.35, <i>p</i> = 0.021, <i>p_FDR</i> = 0.042) problems in middle childhood. Higher average parent praise also marginally predicted fewer externalizing problems (<i>r</i> = −0.33, <i>p</i> = 0.006, <i>p_FDR</i> = 0.057).

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.

Prior work has established that infants rely on a variety of cues available in the speech signal (i.e., prosodic, statistical, acoustic-segmental, and lexical) to accomplish this task. In two experiments with French-learning 6- and 10-month-olds, we use a psychoacoustic approach to examine if and how degradation of the two fundamental acoustic components extracted from speech by the auditory system, namely, temporal (both frequency and amplitude modulation) and spectral information, impact word form segmentation. Infants were familiarized with passages containing target words, in which frequency modulation (FM) information was replaced with pure tones using a vocoder, while amplitude modulation (AM) was preserved in either 8 or 16 spectral bands. Infants were then tested on their recognition of the target versus novel control words. While the 6-month-olds were unable to segment in either condition, the 10-month-olds succeeded, although only in the 16 spectral band condition. These findings suggest that 6-month-olds need FM temporal cues for speech segmentation while 10-month-olds do not, although they need the AM cues to be presented in enough spectral bands (i.e., 16). This developmental change observed in infants’ sensitivity to spectrotemporal cues likely results from an increase in the range of available segmentation procedures, and/or shift from a vowel to a consonant bias in lexical processing between the two ages, as vowels are more affected by our acoustic manipulations.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Research Highlights</h3>\u0000 \u0000 <div>\u0000 <ul>\u0000 \u0000 <li>Although segmenting speech into word forms is crucial for lexical acquisition, the acoustic information that infants’ auditory system extracts to process continuous speech remains unknown.</li>\u0000 \u0000 <li>We examined infants’ sensitivity to spectrotemporal cues in speech segmentation using vocoded speech, and revealed a developmental change between 6 and 10 months of age.</li>\u0000 \u0000 <li>We showed that FM information, that is, the fast temporal modulations of speech, is necessary for 6- but not 10-month-old infants to segment word forms.</li>\u0000 \u0000 <li>Moreover, reducing the number of spectral bands impacts 10-month-olds’ segmentation abilities, who succeed when 16 bands are preserved, but fail with 8 bands.</li>\u0000 </ul>\u0000 </div>\u0000 </section>\u0000 </div>","PeriodicalId":48392,"journal":{"name":"Developmental Science","volume":"27 5","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/desc.13533","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141297084","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}

Prior work has established that gender essentialism in children correlates with prejudice against people who do not conform to gender norms, but to date no causal link has been established. The present study investigated this link more directly by testing whether children's gender essentialism and prejudice against gender nonconformity can be reduced by exposure to anti-essentialist messaging. Children ages 6–10 years of age (&lt;i&gt;N &lt;/i&gt;= 102) in the experimental condition viewed a short video describing similarities between boys and girls and variation within each gender; children in the control condition (&lt;i&gt;N &lt;/i&gt;= 102) viewed a corresponding video describing similarities between two types of climate and variation within each. Children then received measures of gender essentialism and prejudice against gender nonconformity. Finally, to ask whether manipulating children's gender essentialism extends to another domain, we included assessments of racial essentialism and prejudice. We found positive correlations between gender essentialism and prejudice against gender nonconformity; both also correlated negatively with participant age. However, we observed no differences between children in the experimental versus control conditions in overall essentialism or prejudice, indicating that our video was largely ineffective in manipulating essentialism. Accordingly, we were unable to provide evidence of a causal relationship between essentialism and prejudice. We did, however, see a difference between conditions on the discreteness measure, which is most closely linked to the wording in the video.

Among a sample of 180 mostly White middle-class families (91 girls), we examined if childcare participation in infancy was related to two aspects of EF (Delay and Conflict) at 3 years, and whether two aspects of maternal parenting behavior (sensitivity and autonomy support) moderated these associations.

Although a belief in upward mobility (e.g., that status can improve) can be helpful for economically disadvantaged adolescents and adults, a belief in upward social mobility in adults is also associated with greater acceptance of societal inequality. While this belief might have similar benefits or consequences in children, no previous work has examined whether children are even capable of reasoning about social mobility. This is surprising, given that elementary-aged children exhibit sophisticated reasoning about both social status, as well as about the fixedness or malleability of properties and group membership. Across an economically advantaged group of 5- to 12-year-old American children (<i>N</i> = 151, <i>M_age</i> = 8.91, 63% racial majority, 25% racially marginalized; <i>M</i>_{household income}= $133,064), we found evidence that children can reason about social mobility for their own families and for others. Similar to research in adults, children believe that others are more likely to experience upward than downward mobility. However, in contrast to adult's typical beliefs—but in line with economic realities—between 7- and 9-years-old, children become less likely to expect upward mobility for economically disadvantaged, versus advantaged, families. In sum, children are capable of reasoning about social mobility in nuanced ways; future work should explore the implications of these beliefs.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Research Highlights</h3>\u0000 \u0000 <div>\u0000 <ul>\u0000 \u0000 <li>Despite harsh economic realities, a belief in upward social mobility and the American Dream is alive and well.</li>\u0000 \u0000 <li>Between 7 and 9 years of age, economically advantaged, American children begin to expect economically disadvantaged families to experience less upward mobility than economically advantaged families.</li>\u0000 \u0000 <li>Children's beliefs about social mobility better accord with reality than adults’ do.</li>\u0000 </ul>\u0000 </div>\u0000 </section>\u0000 </div>","PeriodicalId":48392,"journal":{"name":"Developmental Science","volume":"27 5","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141082761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Across cultures, speech and music are two dominant auditory signals in infants’ daily lives. Decades of research have repeatedly shown that both quantity and quality of speech input play critical roles in infant language development. Less is known about the music input infants receive in their environment. This study is the first to compare music input to speech input across infancy by analyzing a longitudinal dataset of daylong audio recordings collected in English-learning infants’ home environments, at 6, 10, 14, 18, and 24 months of age. Using a crowdsourcing approach, 643 naïve listeners annotated 12,000 short snippets (10 s) randomly sampled from the recordings using Zooniverse, an online citizen-science platform. Results show that infants overall receive significantly more speech input than music input and the gap widens as the infants get older. At every age point, infants were exposed to more music from an electronic device than an in-person source; this pattern was reversed for speech. The percentage of input intended for infants remained the same over time for music while that percentage significantly increased for speech. We propose possible explanations for the limited music input compared to speech input observed in the present (North American) dataset and discuss future directions. We also discuss the opportunities and caveats in using a crowdsourcing approach to analyze large audio datasets.
