Abstract: The main goal of this research was to determine the role played by visual imagery and spatial thinking in high level cognition, such as in problem-solving and reasoning. In conjunction with the experimental work, the project developed a computational modeling system (4CAPS) as well as the development of 4CAPS models for particular tasks. The cognitive level of 4CAPS accounts for human errors and performance times in various tasks, whereas the cortical modeling accounts for the time course and amplitude of the brain activation in a number of cortical areas (focusing on association cortex). The overall scientific objectives were to characterize the brain activation and cognitive processes underlying mental imagery and visual thinking, particularly as they apply to the use of vehicle navigation systems. The research explored display technologies and task variables that affect human performance and brain activity.
