Aleman et al. (2001)

From Psy3242

This study looks at the most common form of synesthesia, seeing the words you hear in color (colored hearing). Aleman et. al. longed to find if the primary visual cortex (V1) would be triggered during “conscious visual perception without visual stimulation.” The subject in this study was a 32-year-old woman who reported having colored hearing since childhood. In the first test, she was asked to say what color she associated with each letter of the alphabet (alphabet-color test). Two years later, she was given the same test during an fMRI. She only missed one letter, for a 96% accuracy rate.
