干扰抑制对前瞻记忆影响的认知机制

The Cognitive Mechanism of Interference Control of the Effect on Prospective Memory

本文设计前瞻记忆新范式计数干扰任务,选取大学生和初中生为被试,探究干扰抑制对前瞻记忆的作用机制以及年龄因素的影响。结果发现,提高干扰抑制负荷后,大学生组的前瞻记忆成绩仅在中断模式下显著降低,初中生组在中断和非中断模式下均有明显下降,这说明中断模式下干扰抑制更多参与了前瞻记忆的认知加工,且这种作用机制受到了年龄因素的影响。

To explore the mechanism of interference control on prospective memory and the influence of age factor, the study designed the counting interference task as a new paradigm for prospective memory and selected college students and junior high school students as subjects. Results showed that after improving the interference control load, the prospective memory performance of college students was significantly reduced only in interruption mode, and junior high school students’ performance was significantly reduced in both interruption and non-interruption modes. This showed that interference control in interruption mode was more involved in the cognitive processing of prospective memory, which was influenced by age.
