Insights

Children aged 8-10 show the most significant improvements in attention and executive functions, like response inhibition and selective attention. Performance plateaus by age 10, suggesting parallel development with frontal brain functions.

Area of Science:

  • Developmental Psychology
  • Neuroscience
  • Cognitive Science

Background:

  • Executive functions and attention are critical for cognitive development.
  • Understanding their developmental trajectory in children is essential for identifying potential deficits.

Purpose of the Study:

  • To investigate the developmental trajectory of attention and executive functions in typically developing children aged 7-12 years.
  • To assess the utility of a novel selective reaching task for measuring multiple cognitive dimensions simultaneously.

Main Methods:

  • A novel selective reaching task was employed, requiring rapid target reaching while ignoring distractors.
  • This task measured vigilance, set-shifting, response inhibition, selective attention, and impulsive responding.

Main Results:

  • Significant improvements in all measured functions were observed between ages 8 and 10.
  • Performance plateaued between ages 10 and 12.
  • Developmental gains aligned with a step-wise model and frontal brain function development.

Conclusions:

  • Attention and executive functions develop in parallel during childhood.
  • The selective reaching task is a valuable tool for assessing these functions and may aid in identifying cognitive impacts in childhood disorders.

Information Processing Approach01:30

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is also...
Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
