Abstract
Living in a complex world, our cognitive system has to rely on efficient processes to attend to task-relevant objects while ignoring the currently irrelevant and possibly interfering ones. In this talk I compare ignoring of distracting stimuli between vision and touch. In particular, aftereffects of ignored distractors (i.e.Negative Priming) were found to be different for visual as compared to tactile distractors. Tactile distractors led to larger effects as visual ones and were observed under conditions in which no effects are typically reported using visual material (Frings, Amendt, & Spence, 2011). In addition, Gestalt or grouping effects modulated the processing of tactile distractors in a more complex fashion as compared to vision (Frings & Spence, in revision). In sum, so far the evidence suggests differences in distractor processing between the modalities.
