Working Memory Trial Data

This database contains cognitive testing data from healthy young adults (aged 18-40) who participated in a randomized trial of online working memory training compared to both active and passive control groups. All participants are English speaking, and data were collected at the University of Calgary, Calgary, Alberta, Canada, between 2015 and 2016. Participants were recruited via printed advertisements distributed throughout the community. Study involvement included completing cognitive tests of general intelligence, fluid intelligence, and working memory both before and after approximately 6 weeks of online working memory training, processing speed training (active control condition), or no contact with experimenters. Participants also completed several questionnaires regarding demographic and psychological variables. Functional and structural neuroimaging data was also collected before and after the training period for those assigned to the working memory training group and the processing speed active control group. Of the 107 participants that consented to participate, a total of 76 were included in the final analyses. The University of Calgary Conjoint Faculties Research Ethics Board approved this study, and all participants provided written informed consent.
