The physiological basis of hypothesized adult age increases in the persistence of stimuli was studied in 16 young (X age 19.1 years) and 16 old (X age 70.1 years) male and female subjects. Changes in CFF threshold and skin conductance were measured as a function of loud white noise activation and artificial pupil. CFF was significantly lower in the old group and with artificial pupil in both age groups. Significant effects were also found for activation x sex and activation x age x sex. Skin conductance change was significant for activation, activation x sex, artificial pupil x age, artificial pupil x order and artificial pupil x order x activation. The results were interpreted as supporting an overarousal basis of an age increase in stimulus persistence.
在16名年轻(平均年龄19.1岁)和16名年长(平均年龄70.1岁)的男性和女性受试者中,研究了假设的成年人随着年龄增长刺激持续存在的生理基础。测量了临界闪光融合频率(CFF)阈值和皮肤电导率随大声白噪声激活和人工瞳孔的变化。年长组的CFF显著较低,且两个年龄组中人工瞳孔条件下的CFF也较低。还发现激活×性别以及激活×年龄×性别存在显著影响。皮肤电导率变化在激活、激活×性别、人工瞳孔×年龄、人工瞳孔×顺序以及人工瞳孔×顺序×激活方面具有显著性。结果被解释为支持刺激持续存在随年龄增长的过度唤醒基础。
