Summary

Young children develop attentional control, crucial for managing emotions and behavior. By 30 months, they can resolve spatial conflicts, linking better attention to fewer behavioral issues.

Area of Science:

  • Developmental psychology
  • Cognitive neuroscience
  • Child temperament studies

Background:

  • Effortful control shows an inverse relationship with negative affectivity across development.
  • Effortful control is linked to conscience development and acts as a protective factor against behavioral disorders.

Purpose of the Study:

  • To investigate the development of attentional mechanisms underpinning effortful control in 2- to 3-year-old children.
  • To examine children's ability to make anticipatory eye movements and resolve spatial conflict.
  • To correlate these attentional abilities with parent-reported temperament.

Main Methods:

  • Assessed anticipatory eye movements to ambiguous locations in a sequential task.
  • Evaluated performance on a spatial conflict task involving location and identity.

Related Experiment Videos

  • Correlated eye-movement task performance with spatial task performance and reaction times.

    • Main Results:

    • Anticipatory eye movements to ambiguous locations were present by 24 months.
    • By 30 months, children could perform the spatial conflict task.
    • Success in the spatial conflict task at 30 months correlated with better performance on the ambiguous eye-movement task.

    Conclusions:

    • Attentional mechanisms supporting effortful control develop significantly between 24 and 30 months.
    • These developing attentional abilities are related to parent-reported temperament, including negative affectivity.
    • Findings suggest early attentional development is a key factor in emotional and behavioral regulation.
