“…Third, it might be that the stimuli used here allowed for better estimation of prime perception, d′ . In previous studies (e.g., Finkbeiner, 2011; Muscarella et al, 2013), the prime and target have been perceptually similar (i.e., both words) so the target could interfere with the prime response, which would lead to underestimated prime perception, d′ (Vermeiren and Cleeremans, 2012). In contrast, in the current experiment, primes and targets were highly dissimilar (i.e., a word and colored rectangle); as discussed by Van den Bussche et al (2013), this makes it easier for participants to judge whether or not they perceived the prime.…”
