计划能力在许多日常任务中都很重要，比如做饭和购物。之前的研究已经调查了年龄对计划的影响，研究对象要么是广泛使用的实验室神经心理学任务，比如伦敦塔（TOL），要么是更自然的计划任务，比如组织购物。在当前的研究中，我们比较了正常成人年龄对TOL和一个更生态有效的计划任务，计划一天（PAD）任务的影响。TOL计划表现随年龄的增长而下降，但年龄与PAD计划表现之间无显著相关性。年龄相关的差异部分可以用信息处理速度和教育程度的差异来解释。在更生态有效的规划任务中，处理速度的年龄变化可以通过任务相关知识来补偿。考虑对老年人日常规划绩效的影响。
Planning ability is important in many everyday tasks, such as cooking and shopping. Previous studies have investigated aging effects on planning, looking at either widely used laboratory-based neuropsychological tasks such as the Tower of London (TOL) or more naturalistic planning tasks, such as organizing shopping errands. In the current study, we compare the effects of normal adult aging on both the TOL and a more ecologically valid planning task, the Plan-a-Day (PAD) task. There was a reliable decline in TOL planning performance with age, but no significant correlation between age and PAD planning performance. Age-related variance was partly explained by variance in information processing speed and education. It is proposed that in more ecologically valid planning tasks, age changes in processing speed can be compensated for by task-related knowledge. Implications for everyday planning performance by older adults are considered.
