Effort-related decision-making and its underlying processes during childhood

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Neuroscience

Background:

• Human adults exhibit a general tendency to avoid cognitive effort, but this behavior's developmental trajectory in children remains unclear.
• Existing research on children's effort-based decision-making presents conflicting findings due to varied experimental designs.

Purpose of the Study:

• To investigate the emergence and development of effort-related decision-making in children aged 5 to 11.
• To examine how children make choices between low- and high-effort cognitive tasks.
• To explore cognitive factors influencing these decisions, such as metacognition and effort perception.

Main Methods:

• Utilized a parametric induction of cognitive effort in 79 children (5–11 years old).
• Employed three decision-making paradigms: demand avoidance, effort discounting, and explicit effort manipulation.
• Assessed task performance, metacognitive accuracy, effort perception, and mental demand.

Main Results:

• Children across all age groups reported sensitivity to cognitive effort levels.
• No overall implicit preference for low-effort tasks was observed in children.
• Older children explicitly preferred low-effort tasks, and all children discounted effort.
• Implicit preferences were linked to metacognitive insight into task performance capabilities.

Conclusions:

• Children are sensitive to cognitive effort but their decision-making is influenced by the salience of effortful features.
• The development of effort-based decision-making involves an interplay between cognitive sensitivity and metacognitive awareness.
• Understanding these factors is crucial for comprehending children's engagement with challenging cognitive tasks.
