摘要

We propose that voluntary and involuntary attention affect different mechanisms and have differentconsequences for performance measured in reaction time. Voluntary attention enhances the perceptualrepresentation whereas involuntary attention affects the tendency to respond to stimuli in one locationor another. In a spatial-cueing paradigm, we manipulated perceptual difficulty and compared volun-tary and involuntary attention. For the voluntary-attention condition, the spatial cue was predictive ofthe target location, whereas in the involuntary-attention condition it was not. Increasing perceptualdifficulty increased the attention effect with voluntary attention, but decreased it with involuntaryattention. Thus voluntary and involuntary attention have different consequences when perceptual dif-ficulty is manipulated and hence are probably caused by different mechanisms.
