四个实验考察了与年龄有关的视觉注意返回抑制(IOR)的差异。使用静态刺激时，年轻人和老年人在检测先前暗示的物体中的目标时速度都较慢，表现出相同的IOR。对于在提示后移动的物体，年轻人在检测被提示物体中的目标时速度较慢(与未被提示的物体相比)，显示出基于物体的返回抑制，但老年人在检测这类物体中的目标时速度更快，未能表现出基于物体的返回抑制。两个年龄组在最初提示的位置检测目标的速度都较慢(基于位置的IOR)。结果表明，年龄对返回抑制的影响因抑制参照系的不同而不同：对物体的抑制随年龄的增长而降低，而对地点的抑制则不随年龄的增长而降低。这一结果模式与老年人存在特定的抑制缺陷的观点是一致的。
Four experiments examined age-related differences in inhibition of return (IOR) of visual attention. Using static stimuli, both young and older adults were slower to detect targets in previously cued objects, showing equivalent IOR. With objects that moved after they had been cued, young adults were slower to detect targets in the cued object (compared with uncued ones), revealing object-based IOR, but older adults were faster to detect targets in such objects, failing to demonstrate object-based IOR. Both age groups were slower to detect targets at the initially cued location (location-based IOR). The results show that age has a differential effect on IOR depending on the frame of reference of the inhibition: Inhibition for objects breaks down with age, but that for location does not. This pattern of results is consistent with the view that there are specific inhibitory deficits in old age.
