Abstract

Automatic attentional capture by a salient distractor can be prevented by spatial attentional control settings (ACSs) (e.g., Yantis and Jonides in J Exp Psychol Hum Percept Perform 16:121134, 1990). Earlier, converging evidence for a spatial ACS (Eason et al. 1969) was found in event-related potentials (ERPs). In these studies, the ACS was defined by a single target-relevant location. In an extension, Ishigami et al. (Vis Cogn 17:431456, 2009) demonstrated a successful ACS in performance that was based on multiple (two) target-relevant locations. The purpose of the current study is to seek converging evidence from ERPs for a spatial ACS defined by multiple (two) target-relevant locations, using the methods in Ishigami et al. (Vis Cogn 17:431456, 2009). Any one of four figure-8s brightened uninformatively (cue) before presentation of a digit target calling for a speeded identification (2 or 5). A spatial ACS was encouraged because in different blocks, the digit targets appeared only on the horizontal or vertical axis. Performance was more impaired following the invalid-attended cues than following invalid-unattended cues, consistent with Ishigami et al. (Vis Cogn 17:431456, 2009) and verifying a successful spatial ACS. The direction of attention significantly affected the visual evoked potentials (VEPs) elicited by otherwise identical cues: the amplitudes of early VEPs were greater when the location the cue was presented in was target-relevant than when the location was target-irrelevant. These results reaffirm that attentional capture by irrelevant salient stimuli can be modulated by spatial ACSs defined by multiple target locations in performance and provide converging evidence from ERPs for the previously established behavioral findings.
