Appearance-based inferences bias source memory

Area of Science:

• Psychology
• Social Psychology
• Cognitive Psychology

Background:

• Facial characteristics influence trustworthiness and source memory.
• Babyfaceness elicits spontaneous trait inferences, impacting social cognition.

Purpose of the Study:

• To investigate how babyfaceness and face-behavior congruence affect source memory accuracy.
• To examine the moderating role of target age and task difficulty on these memory biases.

Main Methods:

• Participants viewed younger/older individuals with babyfaced/mature features paired with congruent/incongruent sentences.
• Source memory accuracy for dominance/submission attributions was assessed.
• Task difficulty was manipulated across two experiments.

Main Results:

• Source memory errors were highest when behavior mismatched facial traits and lures shared facial characteristics with the target.
• This effect was moderated by target age in Experiment 1 (older faces more affected) but not in Experiment 2.
• Increased task difficulty reduced the age moderation but maintained the face-behavior congruence effect.

Conclusions:

• Trait expectations from facial maturity bias source memory for own- and other-age faces.
• Own-age faces show less vulnerability to these biases, particularly under increased cognitive load.
• Findings highlight the complex interplay between facial cues, behavior, and age in memory recall.
