Conde et al (2011) reported a modulation of the spatial compatibility effect by the affective valence of soccer team figures. For Favorite team, it was faster to respond by pressing the key located on the stimulus side than the opposite key (ipsi- and contralateral keys, respectively). For Rival team, this pattern was reversed. These findings were interpreted as being due to approach and avoidance reactions which facilitate both the ipsilateral response to a positive stimulus and the contralateral response to a negative one and vice-versa. This hypothesis was challenged by arguing that there is no spatial compatibility effect when a mixed-rule task was used and that approach/avoidance reactions are not elicited when a keyboard was employed to execute the responses. Alternatively, it was proposed that Conde et al. (2011) results were due to task-set effects. Here, emotional faces (Happy, Angry and Fearful) faces were used to test the generality of effects elicited by affective stimuli and to disentangle task-set and approach/avoidance reactions hypotheses. We found that there is no task-set effect when the Happiness-Anger pair was used. Moreover, for the Happiness/Fear pair, there was an interaction between valence and spatial compatibility within a block of trials. These results suggest that: (i) the interaction between valence and spatial compatibility in the Affective SC task modulates the spatial compatibility effect; (ii) this modulation elicits a task-set effect that varies according to the pair of affective stimuli and (iv) the task-set effect may be due to an automatic orientation of the visual attention to the positive stimulus which facilitates the ipsilateral response conjoined with an inhibition of the ipsilateral response to the aversive stimulus, simulating a reversed compatibility effect to the negative stimulus.
