Area of Science:

  • Developmental psychology
  • Neuroscience
  • Cognitive science

Background:

  • Affective decision-making is crucial for navigating complex choices.
  • Understanding its development in early childhood is essential.

Purpose of the Study:

  • To investigate the development of affective decision-making in 3- and 4-year-old children.
  • To examine age-related differences in decision-making strategies.

Main Methods:

  • A simplified version of the Iowa Gambling Task was administered to 48 children.
  • Children chose between two card decks with varying reward and loss structures over 50 trials.

Main Results:

  • Four-year-olds demonstrated more advantageous decision-making than 3-year-olds.
  • Four-year-olds' choices were better than chance, while 3-year-olds' choices were worse than chance.
  • These developmental trends were more pronounced in girls.

Conclusions:

  • Affective decision-making develops rapidly during the preschool years.
  • This development may be linked to the maturation of brain regions like the orbitofrontal cortex.
  • Early childhood is a critical period for the emergence of sophisticated decision-making abilities.
