Individual Differences in Visual Cognition

Abstract

Our research plan had three parts: First, we needed to develop a task battery. This goal has been accomplished; many iterations were required to equate the tasks for difficulty. In fact, the task battery (including a paper-and-pencil version) was modified in response to feedback from Air Force researchers S. Chaiken and P. Kyllonen. Second, we wanted to validate the battery using positron emission tomography (PET). This testing and the preliminary analyses are complete. As expected, the tasks do in fact activate at least sotne distinct brain areas. However, of greater interest is the question of whether individual differences in activation of different areas predicts performance in different tasks. Those analyses are still underway. Finally, the original plan was to use the battery to illuminate the nature of performance in real-world tasks. The period of the grant was reduced, and we have not had time to pursue this line of research. We hope to be able to do so in a subsequent project.
