Virtual reality offers a good possibility for the implementation of real-life tasks in a laboratory-based training or testing scenario. Thus, a computerized training in a driving simulator offers an ecological valid training approach. Visual attention had an influence on driving performance, so we used the reverse approach to test the influence of a driving training on visual attention and executive functions. Thirty-seven healthy older participants (mean age: 71.46 ± 4.09; gender: 17 men and 20 women) took part in our controlled experimental study. We examined transfer effects from a four-week driving training (three times per week) on visual attention, executive function, and motor skill. Effects were analyzed using an analysis of variance with repeated measurements. Therefore, main factors were group and time to show training-related benefits of our intervention. Results revealed improvements for the intervention group in divided visual attention; however, there were benefits neither in the other cognitive domains nor in the additional motor task. Thus, there are no broad training-induced transfer effects from such an ecologically valid training regime. This lack of findings could be addressed to insufficient training intensities or a participant-induced bias following the cancelled randomization process.
虚拟现实为在基于实验室的培训或测试场景中实施现实生活任务提供了很好的可能性。因此,在驾驶模拟器中进行的计算机化培训提供了一种生态有效的培训方法。视觉注意力对驾驶性能有影响,所以我们采用反向方法来测试驾驶培训对视觉注意力和执行功能的影响。37名健康的老年参与者(平均年龄:71.46 ± 4.09;性别:17名男性和20名女性)参与了我们的对照实验研究。我们研究了为期四周的驾驶培训(每周三次)对视觉注意力、执行功能和运动技能的迁移效应。使用重复测量方差分析来分析效应。因此,主要因素是组和时间,以显示我们干预措施与培训相关的益处。结果显示干预组在分散视觉注意力方面有所改善;然而,在其他认知领域以及额外的运动任务中均未发现益处。因此,这种生态有效的培训方案没有产生广泛的训练诱导迁移效应。这一未发现结果可能归因于训练强度不足或随机化过程取消后参与者导致的偏差。
