摘　　要：本研究选取12名大学生、18名老年人,运用SRC任务考察老年人反应抑制能力的发展。研究结果显示:(1)老年人在相容性反应、不相容性反应条件下平均反应时均显著长于大学生,支持速度加工理论。(2)离心率不影响被试反应速度,老年人、大学生对远、近目标表现为相同反应速度。(3)无论是外源线索条件还是内源线索条件,老年人平均冲突效应量均有高于大学生趋势。抑制衰退理论在此有所体现。In current study, 12 university students and 18 older adults participated in the stimulus-response compatibility task. The results showed that the older adults responded more slowly in either compatible response or compatible response, which supported processing speed theory; The eccentricity of target had no influence on partipants, response. The university students and older adults had similar response speed; The older adults had slightly more conflict in either exogenous cue condition or endogenous cue condition, which supported decline in inhibition theory.
