title: Intention formation induces episodic inhibition of distracting stimuli.
abstract: In two experiments we show that (a) distracting stimuli are inhibited after intention formation, (b) this inhibition is episodic rather than semantic in nature, and (c) inhibition of distracting stimuli is terminated once intentions are completed. In both experiments participants were asked to form an intention to press the space bar in response to six cues (i.e. intention cues). After intention formation we measured accessibility of intention cues, of words that are semantically related to the intention cues (i.e. related cues) and of semantically unrelated words (i.e. control cues). In Experiment 1, we obtained slower responses towards related cues compared with both intention cues and control cues in a recognition task, but not in a lexical decision task. In Experiment 2, we showed that inhibition of related cues is terminated after intention completion. Together these results are consistent with theorizing that inhibition of distracting (i.e. related) stimuli is functional for completing previously formed intentions, and give insight in the nature of inhibitory processes during goal pursuit.
