A Cognitive Model of Positive and Negative Congruency Effects in Unmasked Priming: The Role of Attentional Limit and Conflict

Positive priming effect has been found with a short interval between the prime and the target, while negative priming effect (i.e., a congruent prime causes longer RTs) has been found with a long time between the prime and the target. Negative priming effect has been shown mainly using masked priming but some recent studies have shown it without masks (i.e., in unmasked or conscious conditions). We employed our previous model of masked priming for the unmasked condition here, only by removing mask presentation. The model successfully simulated the negative priming effect in unmasked condition found in previous experimental studies.
