Early Infancy and School Entry: Screens Linked to Later Learning Gaps

Early Infancy and School Entry: Screens Linked to Later Learning Gaps

A 502-child longitudinal study finds that screen exposure matters as much by when it happens as how much is viewed. Elevated screen time at age 1 (infancy) and around age 6 (school entry) predicted poorer academic performance at age 9 and weaker working memory at 10.5, while exposure at ages 2–3 showed no lasting effects. The infancy window shows the strongest risk due to displacement of face-to-face interaction; even small population-level shifts toward more screen time could lower overall learning outcomes. Implications point to early-life limits and further research on content, devices, and parental co-viewing.

Infant nutrition linked to lower adolescent IQ, comprehensive review finds

A comprehensive review of 73 studies finds that poor diets in infancy are linked to lower intelligence scores in adolescence, while adolescence as a second opportunity for nutritional intervention remains unsettled; authors call for a life-course framework and seven guiding principles to improve future nutritional neuroscience research.

Adolescent Cannabis Use Linked to Slower Cognitive Growth in Large U.S. Study

Adolescent Cannabis Use Linked to Slower Cognitive Growth in Large U.S. Study

A UC San Diego-led analysis of more than 11,000 youths finds that teens who begin using cannabis show slower gains in memory, attention and processing speed over time, with THC exposure associated with worse memory; CBD exposure showed no clear pattern. The researchers caution that causality isn’t proven and will continue tracking participants into young adulthood to understand long-term effects.

Video Gaming Associated With a Modest IQ Boost in Children, Study Finds

Video Gaming Associated With a Modest IQ Boost in Children, Study Finds

A US ABCD study followed about 9,855 kids aged 9–10, with over 5,000 re-evaluated after two years. Those who spent more time playing video games showed an average IQ increase of roughly 2.5 points beyond the typical rise, even after adjusting for genetics and socioeconomic factors. No significant cognitive effects were found for TV watching or social media. Gains were linked to tasks in reading, visual-spatial processing, memory, flexible thinking, and self-control. The study does not prove causation and did not differentiate game types; more research is needed. Published in Scientific Reports.

Low-Income Bright Children Lose Cognitive Edge in Early Secondary School

A UK study found that bright children from low-income families perform similarly to their wealthier peers until secondary school, after which they experience a sharp decline in attitudes, behavior, mental health, and academic achievement between ages 11 and 14, highlighting the impact of socioeconomic environment on development.

Video Games Boost Kids' IQ, Study Finds

A 2022 study found that children who spend more time playing video games experience a small but notable increase in IQ, challenging the notion that gaming is harmful to young minds. The research, which controlled for genetic and socio-economic factors, suggests that gaming may have positive effects on cognitive abilities, while watching TV and social media showed no significant impact. The findings highlight the complex relationship between screen time and childhood development, emphasizing the need for further research.

Study Reveals Video Games Boost Kids' IQ

A study involving nearly 10,000 children in the US suggests that playing video games may boost intelligence, with those spending more time gaming showing an average increase of 2.5 IQ points over two years. The research, which accounted for genetic and socio-economic factors, found no significant cognitive effects from watching TV or using social media. While the study highlights potential cognitive benefits of gaming, it calls for further research to explore other environmental impacts on childhood brain development.

Toddlers Decode New Words Using Grammar Cues

Toddlers Decode New Words Using Grammar Cues

A study from MIT reveals that toddlers use grammatical focus cues, such as emphasis in speech, to learn new words, challenging the previous belief that children rely on mutual exclusivity to assign meanings. Experiments with 106 children showed that when a word was emphasized, children were more likely to associate it with a new object. This finding highlights the sophisticated linguistic abilities of young children and suggests that they leverage existing grammatical knowledge to acquire new vocabulary.

The Wisdom of Age: Enhanced Decision-Making Skills

The Wisdom of Age: Enhanced Decision-Making Skills

A study published in PLOS Biology reveals that decision-making improves with age due to a decrease in decision noise, which is the variability in choices. Adolescents exhibit higher decision noise, leading to suboptimal choices, but this decreases as they mature, enhancing goal-directed behaviors and adaptability. The research highlights the role of cognitive development in decision-making and suggests that understanding decision noise could provide insights into neurodevelopmental disorders.

Study Finds Asthma May Impair Children's Memory Skills

Study Finds Asthma May Impair Children's Memory Skills

A study from UC Davis links asthma in children to memory deficits, particularly affecting episodic memory. Children with asthma scored lower on memory tasks compared to peers without the condition, with early-onset asthma linked to slower memory development. The study suggests chronic inflammation or oxygen disruption from asthma may impact cognitive development, potentially increasing the risk of dementia later in life. This highlights the importance of monitoring cognitive development in children with asthma.

Study Reveals Patterns in Infant Gaze Behavior

A meta-analysis by researchers from MIT, Northeastern University, and Johns Hopkins University has identified two distinct patterns in infant looking behavior, influenced by different factors. The study, published in Nature Human Behavior, found that looking at unexpected stimuli is influenced by infant age, while looking at visually new stimuli is predicted by habituation rate. These findings suggest that perceptual and conceptual novelty guide infant looking behavior independently, offering new insights into cognitive development.

"Space Invaders Game Boosts Reading Skills in At-Risk Preschoolers"

A study found that preschoolers at risk for dyslexia who played "Space Invaders Extreme 2" for 45 minutes a day, four times a week, over 1.5 months showed significant improvement in phonemic awareness compared to those who underwent traditional speech therapy or played other non-action games. The research suggests that action video games could be an effective tool for early intervention in children at risk for dyslexia and potentially other neurodevelopmental disorders.
