In this experiment we studied the cognitive processes involved in problem solving. Using EEG we examined brain activation involved in two tasks that seem to be very different on the surface to discover if these tasks rely on the same underlying mechanisms. The hypothesis was that both tasks rely on the same declarative and working memory system. This was done by manipulating retrieval and transformation in an algebra task and in a word swapping task. Analysis of the behavioural data showed significant differences in accuracy and reaction time when retrieval and transformation were manipulated in both tasks. Analysis of the EEG data also showed similar patterns in activation between tasks, supporting the hypothesis. While this is a step towards understanding how these task processes function in the brain, a more in depth comparison of the underlying mechanisms of two seemingly different tasks is needed using the power of a statistical model.
