三个实验考察了成人在内源性(自愿)和外源性(非自愿)注意力转移效率上的年龄差异。在空间线索任务中，年轻和年长的被试在目标刺激之前以50到250毫秒的间隔呈现突然出现的外周线索(实验1)或中央符号线索(实验2和3)。对于外围线索，老年人的线索效应至少和年轻人一样大，并且遵循类似的时间进程。符号线索也得到了类似的结果，尽管老年人的线索效应因线索难度的不同而不同。结果表明，线索编码可能会随着年龄的增长而下降，但转移过程的效率保持不变。
Three experiments examined adult age differences in the efficiency of endogenous (voluntary) and exogenous (involuntary) attention shifts. Younger and older subjects performed a spatial cuing task in which abruptly onset peripheral cues (Experiment 1) or central, symbolic cues (Experiments 2 and 3) were presented before a target stimulus at intervals ranging from 50 to 250 ms. With peripheral cues, the magnitude of cuing effects was at least as great for older as for younger adults and followed a similar time course. Similar results were obtained with symbolic cues, although cuing effects for older adults varied with cue difficulty. The results suggest that cue encoding may decline with advancing age but that the efficiency of the shift process is preserved.
