The present study aimed at investigating the processing stage underlying stimulus–stimulus (S–S) congruency effects by examining the relation of a particular type of congruency effect (i.e., the ﬂanker effect) with a stimulus–response (S–R) spatial correspondence effect (i.e., the Simon effect). Experiment 1 used a unilateral ﬂanker task in which the ﬂanker also acted as a Simon-like accessory stimulus. Results showed a signiﬁcant S–S Congruency S–R Correspondence inter- action: An advantage for ﬂanker–response spatially corresponding trials was observed in target– ﬂanker congruent conditions, whereas, in incongruent conditions, there was a noncorresponding trials’ advantage. The analysis of the temporal trend of the correspondence effects ruled out a tem- poral-overlap account for the observed interaction. Moreover, results of Experiment 2, in which the ﬂanker did not belong to the target set, demonstrated that this interaction cannot be attributed to perceptual grouping of the target–ﬂanker pairs and referential coding of the target with respect to the ﬂanker in the congruent and incongruent conditions, respectively. Taken together, these ﬁnd- ings are consistent with a response selection account of congruency effects: Both the position and the task-related attribute of the ﬂanker would activate the associated responses. In noncorresponding- congruent trials and corresponding-incongruent trials, this would cause a conﬂict at the response selection stage.
