Recent studies using the spatial interference paradigm have found qualitative differences regarding the congruency effect observed for gaze and arrows: whereas arrow targets elicit the usual standard congruency effect (SCE), gaze targets elicit a reversed congruency effect (RCE). It has been proposed that gaze targets would produce the same SCE produced by arrows, but also an additional opposite social component that would lead to the observed RCE. To test this proposal, in this study we investigated whether the presence of a pre-cueing and an alerting signal, which have been shown to respectively reduce and increase the SCE, also modulate the RCE (respectively increasing/reducing the reversion of the congruency effect). We divided the experiment into two blocks, a cueing block with a peripheral non-predictive cue presented 100 ms before the target, and an alerting block with a 2000-Hz tone present in 50% of the trials 450 ms before the target. The results showed that part of our preregistered hypotheses was corroborated, observing a SCE and a RCE in the standard conditions, i.e., for the un-cued location trials in the cueing block, and when the tone was absent in the alerting block. However, when the tone was present, we observed an increment of the congruency effect for arrows, and a more negative effect with gaze (instead of the predicted reduction). In the cueing block, the expected reduction of the SCE on cued trials was observed with arrows. However, when gaze was used as a target, a decreased, rather than increased RCE was also observed on cued trials. In other words, cueing and alerting manipulations produced opposite rather than similar effects for arrow and gaze targets. These results suggest that although the spatial interference component produced by gaze and arrows might share some specific equivalent mechanisms and be similarly modulated with some manipulations, they are differently affected by others.

Abstract
Recent studies using the spatial interference paradigm have found qualitative differences regarding the congruency effect observed for gaze and arrows: whereas arrow targets elicit the usual standard congruency effect (SCE), gaze targets elicit a reversed congruency effect (RCE). It has been proposed that gaze targets would produce the same SCE produced by arrows, but also an additional opposite social component that would lead to the observed RCE. To test this proposal, in this study we investigated whether the presence of a pre-cueing and an alerting signal, which have been shown to respectively reduce and increase the SCE, also modulate the RCE (respectively increasing/reducing the reversion of the congruency effect). We divided the experiment into two blocks, a cueing block with a peripheral non-predictive cue presented 100 ms before the target, and an alerting block with a 2000-Hz tone present in 50% of the trials 450 ms before the target. The results showed that part of our preregistered hypotheses was corroborated, observing a SCE and a RCE in the standard conditions, i.e., for the un-cued location trials in the cueing block, and when the tone was absent in the alerting block. However, when the tone was present, we observed an increment of the congruency effect for arrows, and a more negative effect with gaze (instead of the predicted reduction). In the cueing block, the expected reduction of the SCE on cued trials was observed with arrows. However, when gaze was used as a target, a decreased, rather than increased RCE was also observed on cued trials. In other words, cueing and alerting manipulations produced opposite rather than similar effects for arrow and gaze targets. These results suggest that although the spatial interference component produced by gaze and arrows might share some specific equivalent mechanisms and be similarly modulated with some manipulations, they are differently affected by others.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
