Delayed Development of Self-Control Compared to Working Memory in Teenagers Revealed by Extensive Study

Unlocking the Adolescent Mind

According to НВ — Техно: An expansive international study involving more than 45,000 teenagers from China and the United States has uncovered that self-control and impulse regulation mature later than working memory. Researchers from several Chinese institutions examined executive brain functions in adolescents aged 11 to 18. These findings provide valuable benchmarks for assessing cognitive growth and supporting adolescent mental well-being.

Key Findings from the Research

The study analyzed data from 33,622 Chinese teenagers, with the results validated by an additional sample of 11,549 American adolescents. Scientists compared inhibitory control and working memory by employing reaction time tests that included stop-signal tasks to evaluate self-regulation. Working memory was assessed through sequence memorization exercises. The data showed that working memory reaches maturity earlier, whereas inhibitory control continues to develop throughout late adolescence.

The research also highlights that deviations from typical age-related development in executive functions are linked to increased mental health risks. Such deviations were associated with:

• hyperactivity,
• inattention,
• communication difficulties,
• behavioral problems.

Early adolescence appears to be the most vulnerable period for mental health challenges, though the connection between executive function irregularities and mental health issues tends to weaken among older teenagers.

Understanding how cognitive functions evolve during adolescence is crucial, especially as young people face growing stress in today's fast-paced world. Insights into the timeline of self-control development can aid in early identification of potential issues and timely mental health interventions. This landmark study not only informs support programs but also opens avenues for future research into adolescent brain development.

As the understanding of cognitive development in adolescents deepens, recent findings from a comprehensive study reveal that increased screen time may have a surprising link to enhanced cognitive abilities. This intriguing perspective complements the insights on self-control and working memory maturation.
