Working Memory Training in Healthy Adults

This is a database of healthy adults, aged 30-60, who participated in a study comparing online working memory training to online processing speed training. Participants are English speaking and data was collected at the University of Calgary, Calgary, Alberta, Canada between 2011-2013.Participants completed a demographics questionnaire, a brief measure of intelligence (Wechsler Abbreviated Scale of Intelligence; WASI), and measures of working memory, processing speed, and fluid intelligence. After completing 5-weeks of working memory training or processing speed training, participants again completed measures of working memory, processing speed, and fluid intelligence. Of the 81 participants who consented to participate, 61 (75%) completed baseline and post-training testing. Four participants were removed from analysis due to low training dosage, resulting in 57 participants.The University of Calgary Conjoint Faculties Research Ethics Board approved this study, and all participants provided written informed consent. <br>

本数据集为健康成人受试数据库，受试年龄介于30至60岁之间，参与一项对比在线工作记忆训练与在线加工速度训练的研究。所有受试均为英语使用者，数据采集工作于2011至2013年间在加拿大阿尔伯塔省卡尔加里市的卡尔加里大学完成。
受试需完成人口学问卷、简易智力测评（韦氏简智力量表，Wechsler Abbreviated Scale of Intelligence, WASI），以及工作记忆、加工速度与流体智力相关测评。在完成为期5周的在线工作记忆训练或在线加工速度训练后，受试再次完成工作记忆、加工速度与流体智力相关测评。
初始共有81名受试签署参与同意书，其中61名（占比75%）完成了基线与训练后测评。另有4名受试因训练剂量不足被排除出分析队列，最终有效受试共57名。
本研究已通过卡尔加里大学联合学院研究伦理委员会审批，所有受试均签署了书面知情同意书。
