We report three experiments designed to investigate interference effects in an auditory analog of Eriksen's visual flanker interference task (e.g. [1, 2]). In Experiment 1, participants made speeded auditory 'bat' versus 'bed' discrimination responses to a series of target words presented from a central loudspeaker while simultaneously trying to ignore auditory flanker words ('bat' or 'bed') presented from two loudspeakers positioned 30 degrees to either side of fixation. Participants respond...
