[Two types of facial impression judgments and recognition memory for faces]

Area of Science:

• Cognitive Psychology
• Social Psychology
• Neuroscience

Background:

• Facial recognition memory is crucial for social interaction.
• Semantic processing, or understanding meaning, may influence memory recall.
• The impact of personality traits on facial recognition requires further investigation.

Purpose of the Study:

• To examine the semantic processing advantage effect on facial recognition memory.
• To differentiate the influence of expression-independent versus expression-dependent personality traits.
• To assess recognition memory under varying facial expressions and recognition conditions.

Main Methods:

• Experiment 1: Selected personality trait words based on facial impression ratings.
• Experiment 2: Participants rated faces on physical or personality traits, followed by a yes-no recognition test.
• Recognition tests included identical pictures and expression-changed pictures of faces.

Main Results:

• A semantic processing advantage was found in both expression-dependent and independent trait groups for identical-picture recognition.
• In expression-changed recognition, the advantage was significant only for the expression-independent trait group.
• Results suggest stable personality traits enhance facial recognition memory.

Conclusions:

• Semantic-codes explanation is plausible for the observed effects.
• Expression-independent traits, linked to stable semantic information, better support facial recognition memory.
• The findings contribute to understanding memory mechanisms and social cognition.
