Preview The Synesthesia Battery

The Synesthesia Battery aims to understand and objectively quantify synesthetic perception.
The first part of the battery is a comprehensive questionnaire that gathers information about the types of synesthesia, their characteristics, and relevant information about the synesthete.

Grapheme→Color Synesthesia is one of the most common varieties of synesthesia for which we have developed two types of software programs.

The Color-Picker program allows the synesthete to assign colors to the graphemes presented in random order with repetitions. Click here for a short demo version of the program.

Speeded-Congruency is a program that makes the synesthete respond to graphemes presented in colors matching with (congruent) or not matching with (incongruent) colors as chosen on the Color-Picker program. The accuracy and reaction times are measured as a read-out of the synesthetic perception. Click here for a short demo version of the program.
