Disentangling affect from self-esteem using subliminal conditioning

Abstract

Across three experiments, participants underwent conditioning sequences where the self-referential term I AM (Conditioned Stimulus, or CS+) or a scrambled counterpart M IA (CS-) was paired with either neutral (Unconditioned Stimulus, or US-) or positive attributes (US+). CS and US were presented under subliminal and/or visible conditions. A normalized indicator of affective shift and an explicit self-esteem measure were deployed as outcome measures. In Experiment 1 (N = 60), subliminal CS+ followed by visible US+ produced a significant affective shift only. Experiment 2 (N = 59) presented CS and US under subliminal conditions, which did not influence either outcome measure. In Experiment 3 (N = 60), visible CS appeared with visible US, which resulted in a significant effect on explicit self-esteem only. These findings highlight the central roles of CS and/or US visibility towards influencing reported affect and self-esteem. We theorize that configural components of subliminally presented stimuli can become perceptually encoded and influence self-related affect non-consciously.
