Craig Chapman studies how the brain makes decisions that allow people to successfully navigate their world, targeting relevant objects for action and ignoring or avoiding irrelevant ones.
These decisions play an essential role in healthy living, but often fall below conscious awareness. Chapman asks what is the added value of consciousness, and what does it mean for non-conscious decision processing to play such a strong role. The question suggests an important blurring of the distinction between the conscious and the non-conscious. In his lab, Chapman uses a detailed analysis of sensorimotor processing that integrates eye-tracking, electroencephalography and motion-tracking. This has shown that a decision about making a movement doesn’t end once the movement is initiated, but continues until the movement is complete. Therefore, movements provide a window into deciding and thinking, and movement recording is a powerful research tool for science and a diagnostic tool for medicine.
