Thirty-Five Years of Computerized Cognitive Assessment of Aging—Where Are We Now?

Figure 1. (A) average standardized scores on the 12 Cambridge Brain Sciences (CBS) tasks taken at home and in the lab by 19 healthy young adult controls. The results showed no significant effect of at home versus in laboratory testing (F = 1.71, p = 0.2); (B) average raw scores on 4 CBS tasks as well as simple and choice reaction time tasks taken at home and in the lab by 27 patients with Parkinson’s Disease. Again, there was no significant effect of at home versus in-lab testing (p > 0.1) and the tasks showed reliable correlations across the two testing environments (p < 0.05).

Figure 2. Average scores on 3 CBS tasks (Digit Span, Spatial Span and Token Search), taken at home and in the lab by more than 100 young adult controls. The results showed no significant effect of at home versus in laboratory testing [35]. In the case of Token Search (lower panel), the overlap in performance for participants tested at home using Amazon’s MTurk and those tested in the laboratory persisted even after several weeks of intensive training on the task [35].

Figure 3. The CBS composite score was highly correlated with Montreal Cognitive Assessment (MoCA) scores and better differentiated impaired and unimpaired individuals. The border colour of each datapoint indicates the categorization of individuals based on MoCA scores alone. The fill colour indicates to which group borderline participants are categorized when the composite score of 3 CBS tests is used.
