Eliminating age differences in children's and adults' suggestibility and memory conformity effects

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Memory Research

Background:

• Typical developmental trends suggest a decrease in suggestion-induced false memories with age.
• Spontaneous false memory principles offer insights into modifying these developmental trends.

Purpose of the Study:

• To investigate if developmental trends in suggestion-induced false memories can be altered.
• To examine age-related differences in misinformation effects and memory conformity.

Main Methods:

• Experiment 1 adapted the misinformation procedure with stories and subsequent misleading narratives for children and adults.
• Experiment 2 utilized a memory conformity paradigm with paired picture viewing and collaborative/individual recall for different age groups.
• Participants included children (7-12 years) and adults.

Main Results:

• Children and adults demonstrated equal susceptibility to the misinformation effect in Experiment 1.
• Both age groups exhibited similar memory conformity effects in Experiment 2.
• After correcting for response bias, adults showed higher false memory scores than children.

Conclusions:

• Age trends in suggestion-induced false memories are not developmentally invariant.
• The study challenges the assumption of a consistent age-related decrease in false memories.
• Findings suggest that external factors and memory procedures can influence developmental trajectories of false memory formation.
