Causal Relationships Between Screen Use, Reading, and Brain Development in Early Adolescents

Advanced Science, Journal Year: 2024, Volume and Issue: 11(11)

Published: Jan. 2, 2024

Abstract The rise of new media has greatly changed the lifestyles, leading to increased time on these platforms and less spent reading. This shift particularly profound impacts early adolescents, who are in a critical stage brain development. Previous studies have found associations between screen use mental health, but it remains unclear whether is direct cause outcomes. Here, Adolescent Brain Cognitive Development (ABCD) dataset utlized examine causal relationships results revealed adverse effects language ability specific behaviors while reading positive their volume frontal temporal regions. Interestingly, identified as result, rather than cause, certain such rule‐breaking aggressive behaviors. Furthermore, analysis uncovered an indirect influence use, mediated by changes habits, These findings provide evidence for influences development highlight importance monitoring related habit change children.

Screen exposure, sleep quality, and language development in 6-month-old infants

Frontiers in Developmental Psychology, Journal Year: 2025, Volume and Issue: 3

Published: Feb. 12, 2025

Introduction Screen time can have important ramifications for children's development and health. Children exposed to greater screen score lower on assessments of language tend sleep less. However, most studies examining associations among time, development, quality focused older children and/or relied subjective exposure (i.e., parent report). The current study examined whether exposure, assessed via both maternal-report questionnaires in-home audio recordings, was associated with differences in infants at ~6 months age ( N = 187). Methods Mothers completed assess infant production, quality, as well family socioeconomic demographic factors. Language Environment Analysis (LENA) recorder used measure home use the environment. Results Higher income higher maternal education were less by report LENA recordings. Neither significantly environment, maternally-reported or quality. Maternally-reported showed a small but significant positive correlation LENA-derived exposure. Discussion We find no detectable association between maternally reported first 6 life.

Longitudinal sex-at-birth and age analyses of cortical structure in the ABCD Study^®

Abstract While the brain continues to develop during adolescence, such development may depend on sex-at-birth. However, elucidation of differences be hindered by analytical decisions (e.g., covariate selection address body/brain-size differences) and typical reporting cross-sectional data. To further evaluate adolescent cortical development, we analyzed data from Adolescent Brain Cognitive Development Study SM , whose cohort 11,000+ youth participants with biannual neuroimaging collection can facilitate understanding neuroanatomical change a critical developmental window. Doubly considering individual in context group-level effects, regional changes thickness, sulcal depth, surface area, volume between two timepoints (∼2 years apart) 9-to 12-year-olds assigned male or female First, conducted linear mixed-effects models gauge how controlling for intracranial volume, whole-brain (WBV), summary metric mean thickness) influenced interpretations age-dependent change. Next, evaluated relative thickness area as function sex-at-birth age. Here, showed that WBV (thickness, volume) total were more optimal covariates; different covariates would have substantially altered our overall sex-at-birth-specific development. Further, provided evidence suggest aggregate is changing generally comparable across those sex-at-birth, corresponding happening at slightly older ages Overall, these results help elucidate trajectories early adolescence.

Kidfluencers' lived experiences of influencer culture: a time for regulation?

International Journal of Sociology and Social Policy, Journal Year: 2024, Volume and Issue: 44(11/12), P. 1109 - 1122

Published: June 14, 2024

Purpose “Kidfluencer” is a relatively new term and refers to where young people actively exert influence on lifestyle consumer behaviour through the use of social media. This study focused capturing complexities this phenomenon, issues concern for policymakers that subsequently occur. Design/methodology/approach The used semi-structured interviews capture retrospective experiences ten as “kidfluencers” media platforms, Facebook, Instagram, TikTok YouTube. Findings findings identified several associated with being kidfluencer, such affecting individuals’ work-life balance, their education, how safe they felt online physically, maintained friendships, pressure increase profile mental health well-being. Overall, suggests kidfluencing has specific negative effects kidfluencers childhood experiences, which should be policy makers. Research limitations/implications All participants were above age eighteen. Therefore, contributions reflect upon past, rather than speaking about recent can lead bias. sample size small, reflecting difficulties in accessing sensitive area study. Practical implications provides support decision taken France introduce legislation protects kidfluencers, may suggest need other countries. Originality/value relevant context law adopted by French National Assembly 2020 provide legal framework activities child influencers range platforms. To date, only country laws have been enacted. So far, there no evaluation law, very little research welfare experienced themselves, making timely.

Cognitive processing speed and accuracy are intrinsically different in genetic architecture and brain phenotypes

Published: March 26, 2024

Abstract Since the birth of cognitive science, researchers have used reaction time and accuracy to measure ability. The initial use these two measures is probably a generalization from empiricism, but it also implies that most behavior has fundamental dimensions, namely processing speed (CPS) (CPA). In this study, we genomic-wide association studies (GWAS) data 14 traits show presence those factors revealed specific neurobiological basis underlying them. We found distinct neuroimaging signatures for CPS CPA white matter microstructures were predominantly associated with CPS, while cortical volumes preferably related CPA. identified bases (e.g. excitatory neurons) developmental periods (i.e. late infancy) not CPA, suggesting between function. Moreover, showed differential associations other health-related such as screen exposure sleep status, significant causal relationship psychiatric disorders major depressive disorder schizophrenia. Utilizing an independent cohort Adolescent Brain Cognitive Development (ABCD) uncovered contributions on development young adolescents. These findings various abilities, elucidated brain structural fingerprint genetic architecture hinted at complex interrelationship ability, lifestyle, mental health.
