Dividing attention between the color and the shape of objects

摘要: In many dual-task experiments, the priority observers give to each task is experimentally varied. Most experiments using this methodology have studied effect of dividing attention between spatially distinct objects. We examined performance when had be divided stimulus attributes other than spatial location. first experiment, identified color and shape a single letter. Accuracy was same for single- conditions, trialby-trial analysis revealed strong positive correlation in correct identification shape. second judgments were separated space, with opposite results: Dual-task worse single-task performance, trial-by-trial indicated negative tasks. The results that often only one dimension processed within trial. support object space models attention.
