description <p>The primary focus of this thesis is the development of an automatic Raven’s-like test generator, called Corvus. Corvus was designed to be capable of investigating the relative validity of repeat testing for Raven’s Standard Progressive Matrices (SPM). Raven’s SPM is often considered a ‘Gold Standard’ for general intelligence testing. However, following studies conducted using Corvus, this thesis found evidence that Raven’s SPM lacks validity as a measure of intelligence on repeat testing. Specifically that retesting with Raven’s SPM resulted in the tests losing correlation between item difficulty and time taken per item, while maintaining participant rank order (Spearman’s ρ, n = 53).</p> <p>An additional study using Corvus showed that mouse tracking can enhance information gain in online cognitive testing without significant impact to test score or time. An alternative way of scoring digit span tests was also investigated, and found to address common criticisms of traditional scoring methods.</p> <p>This DPhil was written in an epidemiological context where studies routinely conduct repeat cognitive testing over sustained periods of time to assess cognitive trajectory. However, despite this, there is little research into the validity of repeated cognitive tests.</p> <p>Corvus was designed through an ongoing iterative process together with a detailed quantitative analysis of established Raven’s-like tests. Corvus is made available under an open source licence, for other researchers to use or develop, as are other pieces of code developed as part of this thesis.</p>
