The effect of disagreement on children's source memory performance.

Area of Science:

• Cognitive Development
• Developmental Psychology
• Social Cognition

Background:

• Source memory, crucial for belief formation and social transmission, is hypothesized to be particularly important during interpersonal disagreement.
• Understanding how children process and recall information based on its source is vital for cognitive development research.

Purpose of the Study:

• To investigate if children's source memory performance improves when faced with disagreement.
• To examine the interaction between disagreement and different source types (first-hand vs. second-hand information).
• To assess age-related differences (3- vs. 4-year-olds) in source memory sensitivity to social context.

Main Methods:

• Employed a 2x2 repeated-measures design with 100 children aged 3-4 years.
• Children received information about a container's contents via direct observation or verbal report.
• An interlocutor puppet either agreed or disagreed with the child's subsequent recall, with source memory assessed via free recall and forced-choice questions.

Main Results:

• Four-year-olds, but not three-year-olds, showed improved free recall source memory performance when the interlocutor disagreed, compared to agreement.
• Source memory recall was better for 'being told' (second-hand) information than for 'having seen' (first-hand) information.
• The effect of disagreement on source memory was specific to the free recall measure, not the forced-choice measure.

Conclusions:

• By age four, children's source memory is sensitive to communicative context, particularly disagreement.
• Source memory serves social functions, with disagreement enhancing recall in older preschoolers.
• Findings underscore the developing ability of children to utilize social cues in memory recall.
