Developmental Differences in Subjective Recollection and Its Role in Decision Making.

Area of Science:

• Cognitive Psychology
• Developmental Psychology

Background:

• Subjective assessments of memory recollection significantly influence decision-making processes.
• The relationship between subjective recollection and objective accuracy in memory tasks is complex and warrants further investigation.

Purpose of the Study:

• To investigate how subjective feelings of recollection impact decision-making in a recognition task.
• To examine the dissociation between memory accuracy and subjective recollection across different age groups and experimental conditions.

Main Methods:

• A forced-choice recognition task was employed with varying distractor types (similar to targets vs. similar to other studied items).
• Three experiments assessed 223 participants (including children and adults) across different decision-making constraints.
• Measures included accuracy, subjective recollection claims, and memory selections, particularly in anticipation of rewards.

Main Results:

• In Experiment 1, children and adults showed less accuracy but higher subjective recollection and reward-driven selections in the nonmatch condition.
• This pattern disappeared in younger children (6-7 years) when selection numbers were limited (Experiment 2).
• The pattern re-emerged when selections were required to be counted (Experiment 3), highlighting the role of decision complexity.

Conclusions:

• Subjective recollection can guide decision-making independently of accuracy, especially when choices are less constrained.
• Decision complexity influences children's ability to reflect on their memory confidence and make strategic choices.
• Findings underscore the nuanced interplay between memory, confidence, and decision-making in development.
