The purpose of this study is (1) to understand how the brain processes sensory information and (2) how this is affected by factors like blindness or synesthesia.

Participants will complete simple online tasks, for example judging differences in auditory pitch; processing visual and auditory stimuli in congruent and incongruent pairings; rating the sound-symbolic properties of either real words, pseudowords, or both; or discriminating between two stimuli on the basis of their structural properties over a change in their surface properties, and vice versa.

Amount varies depending on the study
