Consistency
English Synaesthetic consistency is the hallmark of synaesthesia and plays an important role in the definition and validation of synaesthesia. It has been hypothesised that initially unspecified grapheme-colour associations become consistent due to consolidation processes. Thus, we investigated in non-synaesthetes whether repeatedly engaging with grapheme-colour associations mimics the developmental trajectory of synaesthetic consistency in genuine grapheme-colour synaesthesia. This was indeed observed for two experimental groups, irrespective of whether they were instructed to memorize the chosen associations, but not for a passive control group. After the training, associations of the experimental groups
resembled those frequently found in genuine synaesthesia. Furthermore, the acquisition of consistent grapheme-colour associations resulted in a transfer of
benefits to performance in recognition memory for abstract stimuli, as also found in genuine synaesthesia. Our results support the hypothesis that consistent synaesthetic associations are based on consolidation processes due to repeated engagement with graphemes and colours.
