The importance of individual differences in grapheme-color synesthesia.
In this issue of Neuron, Hubbard et al. show individual differences in how grapheme-color synesthetes perform on cognitive tasks. Importantly, these behavioral differences were correlated with fMRI measures. Such individual differences have important ramifications for synesthesia research. If individual differences are ignored, then synesthesia research will be characterized by erroneous conclusions and failures to replicate.
