科学领域:
- 认知神经科学是一种认知神经科学.
- 老年学是一门学科.
- 应用语言学应用语言学
背景情况:
- 假设双语能提供对抗衰老和痴呆症的认知保护.
- 之前的研究还没有系统地研究双语作为缓解与年龄相关的认知衰退的方法.
- 一个新的认知训练计划,双语言干预语义记忆计算机化 (DISC),是为老年人开发的.
研究的目的:
- 与单语言培训和对照组相比,评估双语认知培训计划的有效性.
- 为了确定双语培训是否有利于认知健康和认知障碍的老年人.
主要方法:
- 招募了50名认知健康 (CH) 和48名认知障碍 (CI) 的老年人.
- 参与者被随机分配到单语言 (SL) 组,双语言 (DL) 组或对照组 (没有培训).
- SL和DL组在各自的模式中完成了24个DISC课程;对照组继续正常活动.
主要成果:

Cognitive Development During Adulthood
