Use of affective priming to measure the implicit self-reference effect.

Area of Science:

• Cognitive Psychology
• Social Psychology
• Neuroscience

Background:

• The self-reference effect (SRE) describes enhanced memory for information processed in relation to the self.
• Implicit measures offer insights into unconscious cognitive processes, complementing explicit self-report methods.
• Affective priming, using brief emotional stimuli, can subtly influence judgments and perceptions.

Purpose of the Study:

• To develop and validate an implicit measure of the self-reference effect (Implicit Self-Reference effect, ISR).
• To investigate the influence of affective priming on the implicit self-reference effect.
• To examine how subliminal emotional cues (disgust vs. joy) modulate self-relevance judgments.

Main Methods:

• A modified suboptimal affective priming paradigm was employed.
• Participants (N=26, ages 21-25) judged the self-relevance of hexagrams symbolizing characteristics.
• Suboptimal primes consisted of faces with neutral, disgusted, or joyful expressions (17ms exposure).

Main Results:

• Hexagrams primed with disgusted faces were judged as significantly less self-relevant compared to those primed with joyful faces.
• This finding suggests that negative affective states, even when presented subliminally, can reduce the perceived self-relevance of stimuli.
• The study successfully demonstrated an implicit self-reference effect influenced by affective valence.

Conclusions:

• Affective states significantly modulate the implicit self-reference effect.
• Subliminal negative affect (disgust) can decrease self-referential processing.
• The developed paradigm provides a novel tool for studying implicit self-related cognition and emotion interactions.
