Fundamental Limitations of Human Decision Making
Our lab is interested in understanding the architecture of human information processing. Within this domain, we have focused on the requirements of concurrent task processing. This project is specifically aimed at discovering the fundamental limitations on the decision making aspect of performing multiple tasks. Subjects in dual-task experiments are exposed to stimuli varying on color, shape, size, texture, and/or lexicality for the visual stimuli and tone frequency and/or pitch for auditory stimuli.
In the current experiment, the subject's first task is to identify a letter shown on the computer screen. At the same time the subject is asked to respond to an auditory stimulus. Reaction times for both tasks are measured, and the interference that one task may cause in the other as they are performed concurrently is examined. The primary focus is on decision making behavior during the performance of the multiple tasks.
