在负启动实验中，对老年人抑制过程效率下降的假设进行了验证。负启动被解释为由于先前对后续目标项目的抑制。以20名大学生和20名老年人为研究对象，进行了负启动条件下的视觉选择性注意任务实验。用红色和绿色字母部分重叠的字母阅读任务来评估消极启动的年龄差异。受试者阅读红色字母，忽略绿色字母。结果显示，年龄和分散注意力的信息之间存在显著的相互作用，与年轻人相比，老年人在看到绿色字母时反应更慢。然而，老年人没有表现出负启动效应，而年轻人却表现出负启动效应。这些发现被解释为抑制过程中的年龄缺陷，这可能导致选择性注意任务的表现下降。
The hypothesis that older adults experience a decline in the efficiency of inhibitory processes was tested in a negative priming experiment. Negative priming is interpreted as being due to the previous inhibition of a subsequent target item. An experiment involving a visual selective attention task with a negative priming condition was conducted with 20 college students and 20 older adults. A letter-reading task with partially superimposed red and green letters was used to assess age differences in negative priming. Subjects read red letters and ignored green letters. Results showed a significant interaction between age and the effect of distracting information, with older adults being more slowed by the presence of green letters than young adults. However, older adults failed to show negative priming effects, whereas young adults did show negative priming. These findings are interpreted in the context of age deficits in inhibitory processes, which may lead to decreased performance on selective attention tasks.
