近年来，认知训练作为一种具有成本效益和可获得的干预措施越来越受欢迎，旨在补偿甚至抵消成年期与年龄相关的认知下降。虽然一般认知训练的有效性的证据是不一致的，但处理速度训练是一个值得注意的成功例外，在未经训练的任务和日常认知功能中显示出有希望的普遍益处。这项研究的目的是调查为什么以及何时处理速度训练可以导致整个成人寿命的转移。具体来说，我们将测试（1）在未经训练的情况下，训练引起的证据积累率的变化是否支持转移到认知表现，以及（2）这些转移效应是否随着训练任务的注意力控制需求的增加而增加。我们将采用多中心、纵向、双盲和主动对照研究设计，目标样本量为N = 400例18至85岁的成人受试者。参与者将被随机分配到三种具有不同注意力控制要求（选择反应时间，切换或双重任务）的处理速度训练干预措施中的一种，并将其与具有最小注意力控制要求的简单反应时间任务的主动控制组进行比较。所有小组将完成10个家庭为基础的培训课程，包括三个任务。在训练之前、之后和训练后三个月（即，分别为前测、后测和随访）。我们将使用扩散模型估计证据积累率（漂移率），并进行假设检验的潜在变化评分模型。这项研究将有助于确定在整个成年期内，当训练具有不同注意力控制需求的加速任务时，认知过程会发生变化。更好地了解处理速度训练如何影响特定的认知机制，将使研究人员能够最大限度地提高认知训练的有效性，从而产生广泛的心理意义的日常生活结果。开放科学框架注册中心（Open Science Framework Registries），注册https：//doi.org/10.17605/OSF.IO/J5G7E;注册日期：2022年5月9日。
In recent years, cognitive training has gained popularity as a cost-effective and accessible intervention aiming at compensating for or even counteracting age-related cognitive declines during adulthood. Whereas the evidence for the effectiveness of cognitive training in general is inconsistent, processing speed training has been a notable successful exception, showing promising generalized benefits in untrained tasks and everyday cognitive functioning. The goal of this study is to investigate why and when processing speed training can lead to transfer across the adult lifespan. Specifically, we will test (1) whether training-induced changes in the rate of evidence accumulation underpin transfer to cognitive performance in untrained contexts, and (2) whether these transfer effects increase with stronger attentional control demands of the training tasks. We will employ a multi-site, longitudinal, double-blinded and actively controlled study design with a target sample size of N = 400 adult participants between 18 and 85 years old. Participants will be randomly assigned to one of three processing speed training interventions with varying attentional control demands (choice reaction time, switching, or dual tasks) which will be compared to an active control group training simple reaction time tasks with minimal attentional control demands. All groups will complete 10 home-based training sessions comprising three tasks. Training gains, near transfer to the untrained tasks of the other groups, and far transfer to working memory, inhibitory control, reasoning, and everyday cognitive functioning will be assessed in the laboratory directly before, immediately after, and three months after training (i.e., pretest, posttest, and follow-up, respectively). We will estimate the rate of evidence accumulation (drift rate) with diffusion modeling and conduct latent-change score modeling for hypothesis testing. This study will contribute to identifying the cognitive processes that change when training speeded tasks with varying attentional control demands across the adult lifespan. A better understanding of how processing speed training affects specific cognitive mechanisms will enable researchers to maximize the effectiveness of cognitive training in producing broad transfer to psychologically meaningful everyday life outcomes.
