本研究以探索记忆中意识和无意识贡献大小为目的 ,采用年龄和材料两个自变量 ,年龄分中青年和老年两组 ,被试均为 2 3人 ,材料分文字和非文字两种。实验通过PDP的包含和排除测验计算意识和无意识的贡献大小。结果发现 :(1)意识在不同年龄和不同材料的记忆中所起作用的差异极为显著 ;(2 )无意识在文字材料的记忆中所起作用的差异极为显著 ;(3)无意识在非文字材料和不同年龄的记忆中所起的作用的差异均不显著。由此推论 ,老年人记忆中无意识贡献并未下降。这似说明 ,老年人内隐记忆并未老化。
In order to explore the contribution of consciousness and unconsciousness in memory, this study used two independent variables, age and material. There were 23 youths and seniors in both groups. The subjects were both in literal and nonverbal categories. The experiment passed the inclusion and exclusion test of the PDP to calculate the size of the unconscious and unconscious contributions. The results show that: (1) the difference of consciousness plays an important role in the memory of different ages and different materials; (2) the difference of unconsciousness in the memory of written materials is extremely significant; (3) There was no significant difference in the role of memory in different age groups. It follows that the contribution of unconsciousness in the memory of the elderly has not declined. This may state that the implicit memory of the elderly does not age.
