What does this research mean for the field?

Individualized arousal is more consistently associated with stronger recognition memory confidence for words than individualized valence, exhibiting a nonlinear increase at higher arousal levels. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To examine how individualized arousal and valence ratings relate to recognition confidence for emotional words, and to evaluate how different learning tasks affect subsequent recognition.

Overview

Behavioral experiment reveals higher recognition confidence linked to individualized arousal and semantic encoding in adults, suggesting arousal uniquely shapes subjective memory strength.

Key Points

To examine how individualized arousal and valence ratings relate to recognition confidence for emotional words, and to evaluate how different learning tasks affect subsequent recognition.
Tested 40 participants who encoded neutral, positive, and negative Chinese words under semantic-judgment or recognition-judgment learning conditions.
Administered a six-point old/new confidence recognition test after a 24-hour delay, followed by post-test word ratings for valence and arousal.
Analyzed behavioral responses using linear mixed-effects models and signal-detection metrics, including sensitivity index (d′) and response criterion.
Individualized arousal was more consistently associated with higher old-response confidence than valence, showing a nonlinear increase at high arousal levels.
Semantic-judgment learning led to significantly higher old-item confidence and hit probability than recognition-judgment learning.
Valence-category differences were primarily observed in false-alarm rates, response criteria, and sensitivity estimates rather than the primary confidence model.
