Further toward a model of the Mind’s eye’s movement

An experiment that tests two models to account for shifts of attention in the visual field is described. One model posits that a shift of attention corresponds to a shift in processing resources among several simultaneously analyzed locations. The other model assumes that a shift of attention involves adding a prior stage of analysis that concentrates on the attended location to an otherwise simultaneous processing of several locations. Examination of reaction time distribution characteristics provided support for the latter model.
