Here we examine whether cues not only inXuence the speed with which responses are produced, but also impact or bias which location is ultimately selected as requiring a response. SpeciWcally, can cues inXuence not only the speed with which we respond but also inXuence the behavior produced? To examine this question, a choice localization task was used in which no targets were presented, and subjects were asked to choose which eVector (left hand, right hand) to use in response to a centrally presented tone. Thus, following either a left or right peripheral cue, and then a central tone, subjects were free to respond with either their left or right hand. Early facilitation and later inhibition with this choice procedure were found in both response times and the proportion of responses to the cued and uncued locations. These results suggest that there are processes which initially bias response selection toward cued loca- tions and then subsequently bias response selection away from cued locations.  2006 Elsevier B.V.
