We examined whether self-biases in perceptual matching reflect the positive valence of self-related
stimuli. Participants associated geometric shapes with either personal labels (e.g., you, friend,
stranger) or faces with different emotional expressions (e.g., happy, neutral, sad). They then judged
whether shape-label or shape-face pairs were as originally shown or re-paired. Match times were
faster to self-associated stimuli and to stimuli associated with the most positive valence. In addition,
both the self-bias and the positive emotion-bias were reliable across individuals in different test
sessions. In contrast there was no sign of a correlation between the self-bias and the emotion-bias
effects. We argue that self-bias and the bias to stimuli linked to positive emotion are separate and may
reflect different underlying processes.
