对 4 组年龄不同的 Ss 进行巴甫洛夫心率 (HR) 和眨眼 (EB) 调节评估：年轻 = 19-33 岁，年轻中年 = 35-48 岁，老年中年 = 50-63 岁，老年 = 66-78 岁。 100 毫秒的角膜吹气是无条件刺激，600 毫秒的音调是条件刺激。非联想对照组接受明确不配对的语气和吹气演示。所有 Ss 均进行了 2100 次试验，间隔大约 7 天。老年和中年 Ss 的 EB 和 HR 反应获取均受到损害，但所有年龄组都表现出明显高于对照组的条件作用。第二次训练后，表现略有提高。这些发现表明一般联想过程中存在与年龄相关的障碍。
Pavlovian heart rate (HR) and eyeblink (EB) conditioning were assessed in 4 groups of Ss who differed in age: young = 19-33 years, young middle-aged = 35-48 years, old middle-aged = 50-63 years, and old = 66-78 years. A 100-ms corneal airpuff was the unconditioned stimulus and a 600-ms tone was the conditioned stimulus. A nonassociative control group received explicitly unpaired tone and airpuff presentations. All Ss were studied for 2 100-trial sessions separated by approximately 7 days. An impairment in acquisition of both the EB and HR responses occurred in the old and middle-age Ss, but all age groups showed significantly greater conditioning than did the control group. Slight increases in performance resulted from a 2nd session of training. These findings suggest an age-related impairment in a general associative process.
