Analyzing false memories in children with associative lists specific for their age

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Memory Research

Background:

• Previous research on false memory development in the Deese-Roediger-McDermott (DRM) paradigm yielded contradictory findings.
• The DRM paradigm, a standard tool for studying false memories, has not been extensively applied to very young children.

Purpose of the Study:

• To resolve conflicting results on developmental trends in false memories.
• To adapt and extend the DRM paradigm for use with preschoolers.
• To investigate the impact of age-appropriate associative lists on false memory formation across different age groups.

Main Methods:

• Two experiments were conducted using the DRM paradigm with improved methodology.
• Experiment 1 involved 320 participants across four age groups: 3-4 years (preschoolers), 7-8 years (second-graders), 11-12 years (preadolescents), and adults.
• Experiment 2 involved 64 participants, focusing on preschoolers and preadolescents, utilizing age-appropriate associative lists.

Main Results:

• The use of age-appropriate associative lists significantly increased false recall across all age groups.
• Preschoolers exhibited lower overall false recall compared to older children and adults.
• Despite lower levels, preschoolers demonstrated substantial false memory formation when presented with materials tailored to their age.
• Developmental trends in false memory were observed, with variations across age groups.

Conclusions:

• Age-appropriate materials are crucial for accurately assessing false memory development, particularly in young children.
• The DRM paradigm can be effectively extended to study preschoolers' false memories.
• Findings support theories such as fuzzy-trace theory, source-monitoring framework, and activation-spreading models in explaining false memory development.
