About the Task
Ian Deary is a renowned professor in psychology, particularly known for his work in differential psychology and general intelligence. Together with members of his Edinburgh (Scotland) research group, he published an article about a four-choice response task.
Given that we know that response times correlate with general intelligence, it is useful to have an agreed standard procedure, and the Deary-Liewald task provides this (in a similar way as the Jensen task, Jensen, 2006).
