The main study objective was to investigate the effect of interactive television-based cognitive training on cognitive performance of 119 healthy older adults, aged 60-87 years. Participants were randomly allocated to a cognitive training group or to an active control group in a single-blind controlled two-group design. Before and after training interactive television cognitive performance was assessed on well validated tests of fluid, higher-order ability, and system usability was evaluated. The participants in the cognitive training group completed a television-based cognitive training programme, while the participants in the active control group completed a TV-based programme of personally benefiting activities. Significant improvements were observed in well validated working memory and executive function tasks in the cognitive training but not in the control group. None of the groups showed statistically significant improvement in life satisfaction score. Participants' reports of "adequate" to "high" system usability testify to the successful development and implementation of the interactive television-based system and compliant cognitive training contents. The study demonstrates that cognitive training delivered by means of an interactive television system can generate genuine cognitive benefits in users and these are measurable using well-validated cognitive tests. Thus, older adults who cannot use or afford a computer can easily use digital interactive television to benefit from advanced software applications designed to train cognition.
主要研究目标是调查基于交互式电视的认知训练对119名年龄在60至87岁的健康老年人认知表现的影响。在单盲对照两组设计中，参与者被随机分配到认知训练组或积极对照组。在训练前后，通过经过充分验证的流体、高阶能力测试评估交互式电视认知表现，并评估系统可用性。认知训练组的参与者完成了基于电视的认知训练计划，而积极对照组的参与者完成了基于电视的个人受益活动计划。在经过充分验证的工作记忆和执行功能任务中，认知训练组有显著改善，而对照组没有。两组在生活满意度得分上均未显示出统计学上的显著改善。参与者对系统可用性从“足够”到“高”的报告证明了基于交互式电视的系统和合规认知训练内容的成功开发与实施。该研究表明，通过交互式电视系统进行的认知训练可以为用户带来真正的认知益处，并且可以使用经过充分验证的认知测试来衡量这些益处。因此，无法使用或负担不起计算机的老年人可以轻松使用数字交互式电视，从旨在训练认知的先进软件应用中受益。
