Metacognitive processes in executive control development: the case of reactive and proactive control

Area of Science:

• Cognitive psychology
• Developmental neuroscience
• Executive functions

Background:

• Young children often use reactive cognitive control, responding to events rather than preparing proactively.
• Previous explanations focused on cognitive capacity limitations, but metacognitive control is also key.

Purpose of the Study:

• To investigate whether young children's executive control limitations stem from capacity or metacognitive decision-making.
• To explore the development of proactive cognitive control and its relation to metacognition.

Main Methods:

• Used a task-switching paradigm with three conditions varying cue timing relative to target onset.
• Measured reaction times (RTs), event-related potentials (ERPs), and pupil dilation to assess cognitive control.
• Compared 5-year-olds and 10-year-olds' performance across conditions.

Main Results:

• Five-year-olds demonstrated proactive control (advance preparation) only when reactive control demands were high.
• Ten-year-olds exhibited proactive control more consistently, engaging it whenever possible.
• Behavioral and neural data (RTs, ERPs, pupil dilation) supported these findings.

Conclusions:

• Young children's cognitive control is influenced by metacognitive judgments about when to engage proactive strategies.
• Developmental changes in executive control involve refining metacognitive decision-making, not solely cognitive capacity.
• Highlights the importance of metacognition in the development of executive functions.
