Research in the Goodale Lab has shown that blind echolocation experts use a similar click and echo technique to bats or dolphins to interact and navigate in the world around them. Their studies also revealed that these experts are using what is normally the 'visual' part of their brain to process these clicks and echoes.

Past Research has included exploration of the idea of separate but interactive visual systems - one for perception of objects and one for control of actions directed at those objects. Also, a long term lab goal is to find out how the brain controls the complex behaviour of reaching towards and grasping an object.
