Biological and social influences on cognitive control processes dependent on prefrontal cortex

Area of Science:

• Neuroscience
• Developmental Psychology
• Educational Psychology

Background:

• Executive functions (EFs), including attentional control, self-regulation, working memory, and inhibition, are critical for academic and life success.
• Prefrontal cortex (PFC) development underpins EFs, yet many children enter school with deficits.
• EF disturbances are linked to mental health disorders like ADHD and depression.

Purpose of the Study:

• To explore the biological and environmental factors modulating EFs.
• To discuss the implications of EF development for clinical disorders and education.
• To highlight the PFC's unique vulnerability to genetic and environmental influences via the dopamine system.

Main Methods:

• Review of existing research on EFs, PFC development, and neurochemistry.
• Analysis of environmental influences, including educational programs and early childhood activities.
• Examination of the interplay between genetics, environment, and EF development.

Main Results:

• The prefrontal dopamine system's unusual properties make the PFC particularly susceptible to variations.
• EFs, despite depending on a late-maturing brain region, can be improved early in development.
• Activities like play, physical education, and arts enhance EFs and academic performance, contrary to curriculum-cutting trends.

Conclusions:

• Early interventions focusing on play and arts can improve EFs and academic outcomes.
• Educational and health initiatives should integrate EF development strategies.
• Addressing EF deficits requires a holistic approach, recognizing the intersection of education and health.
