The congruency effect is a slowing of responses for incongruent trials compared to control and congruent trials. Similarly, negation effect is a slowing of responses for negated phrases compared to their affirmative counterparts. Both congruency and negation studies claim ‘conflict’ to be responsible for this slowing. In the present study we further investigated the nature of this conflict in a masked semantic congruency paradigm. In our reaction time experiment, we asked participants to distinguish between animal related words and other words. The experiment consisted of two blocks one with and one without negations. In the latter, semantic congruency was realized by presenting words related to brightness in either white (i.e. congruent) or black (i.e. incongruent) font, while the reverse applied to negated block. For example, the word ‘sun’ presented in white was defined as congruent and the phrase ‘no sun’ in white font was defined as incongruent. We predicted that in negated incongruent conditions two types of conflict would cancel each other out leading to a decrease in reaction time. Our results indicate that there was no difference in reaction time for congruent and incongruent trials. While we found slower reaction times in the negated block, this did not depend on congruency. We propose that the conflict arising from negations should be distinguished from that arising of incongruency. Keywords: Embodied Cognition, Stroop-task, Negations, Conflict
