最近的研究表明，计算机认知训练是有效的治疗，以减少认知能力下降与老化和功能障碍与神经精神疾病。虽然针对特定功能的认知训练和多领域认知训练都被证明具有显著的效果，但我们需要一个简单的行为训练范式来轻松地同时改善多个认知功能领域。我们开发了一种新的计算机化任务，旨在将计划、心算和发散思维等认知功能结合在一项工作记忆任务中。本研究的目的是通过比较健康老年受试者的七个已知的神经心理电池的得分来评估我们的新任务的认知特征。在我们的任务中的性能和获得的神经心理电池的分数之间的关系进行了检查。在我们的任务上的正确表现的百分比与类别流畅性测试，数字广度向后任务，和连线测试B的分数相关。多元逐步回归分析显示，类别流畅性测验和连线测验B的成绩与正确率呈显著正相关。虽然目前的研究并没有显示我们的任务和工作记忆功能作为一个主要目标的正确性能的百分比之间的高度相关性，我们观察到我们的任务和功能的分配注意力和文字流畅性的正确性能的百分比之间的中级相关性。我们的新任务不仅需要工作记忆，还需要注意力和发散思维。因此，这项任务可能是一个有用的工具，同时训练多种认知功能。
Recent studies have indicated that computerized cognitive training is effective as therapy for reducing the cognitive decline with aging and the dysfunction associated with neuropsychiatric illness. Although cognitive trainings that targets a specific function and multi-domain cognitive training have both been shown to have significant effects, we need one simple behavioral training paradigm to improve multiple domains of cognitive functions easily and simultaneously. We had developed a new computerized task that seeks to engage the cognitive functions of planning, mental calculation, and divergent thinking based on a working memory task in a single task. The purpose of this study was to assess the cognitive features of our new task by comparing the scores of seven known neuropsychological batteries in healthy elderly subjects. The relationships between performance in our task and the scores obtained by the neuropsychological batteries were examined. The percentage of correct performance on our task was correlated with the scores on the category fluency test, the digit span backward task, and the Trail making test B. Stepwise multiple regression analyses revealed that the scores on the category fluency test and the Trail making test B showed significant positive correlations with the percentage of correct performance on our task. Although the present study did not show high correlations between the percentage of correct performance on our task and working memory functions as a primary target, we observed mid-level correlations between the percentage of correct performance on our task and functions for divided attention and word fluency. Our new task requires not only working memory, but also attention and divergent thinking. Thus, this task might be a useful tool for training multiple cognitive functions simultaneously.
