Affective Priming Task

The affective priming task, developed by Hermans, De Houwer, and Eelen in 1994, demonstrates that stimulus evaluation is automatic and goal-independent. Like evaluative priming it pairs a valenced prime with a valenced target, but instead of asking participants to judge the target's valence it asks them simply to pronounce or name the target aloud as fast as possible. Targets are named faster when preceded by an affectively congruent prime than an incongruent one, even though the naming task never requires evaluating valence. This is a crucial theoretical point: because evaluation facilitates responding even when it is irrelevant to the task, the affective reaction must be triggered automatically and unintentionally. The naming variant became an important tool for distinguishing genuinely automatic evaluation from response-competition artifacts that can arise in valence-classification tasks.
