This study compared the relationship between computer experience and performance on computerized cognitive tests and a traditional paper-and-pencil cognitive test in a sample of older adults (N = 634).
Participants completed computer experience and computer attitudes questionnaires, three computerized cognitive tests (Useful Field of View (UFOV) Test, Road Sign Test, and Stroop task) and a paper-and-pencil cognitive measure (Trail Making Test). Multivariate analysis of covariance was used to examine differences in cognitive performance across the four measures between those with and without computer experience after adjusting for confounding variables.
Although computer experience had a significant main effect across all cognitive measures, the effect sizes were similar. After controlling for computer attitudes, the relationship between computer experience and UFOV was fully attenuated.
Findings suggest that computer experience is not uniquely related to performance on computerized cognitive measures compared with paper-and-pencil measures. Because the relationship between computer experience and UFOV was fully attenuated by computer attitudes, this may imply that motivational factors are more influential to UFOV performance than computer experience. Our findings support the hypothesis that computer use is related to cognitive performance, and this relationship is not stronger for computerized cognitive measures. Implications and directions for future research are provided.
本研究比较了计算机经验与计算机认知测试和传统纸笔认知测试在老年人群体(N=634)中表现的关系。
参与者完成了计算机经验和计算机态度问卷、三项计算机认知测试(有用视野测试、路标测试和斯特鲁普任务)和一项纸笔认知测试(连线测试)。在调整了混杂变量后,使用协方差的多变量分析比较了有和无计算机经验的参与者在四项测试中的认知表现差异。
尽管计算机经验在所有认知测试中都有显著的主效应,但效应大小相似。在控制了计算机态度后,计算机经验与 UFOV 的关系完全减弱。
研究结果表明,与纸笔测试相比,计算机经验与计算机认知测试的表现并不具有独特的相关性。由于计算机经验与 UFOV 的关系完全被计算机态度所削弱,这可能意味着动机因素对 UFOV 表现的影响比计算机经验更大。我们的研究结果支持了计算机使用与认知表现有关的假设,而且这种关系在计算机认知测试中并不更强。提供了研究的影响和未来方向。
