A time course analysis of the synesthetic colour priming effect.
A currently unresolved issue in research on synesthesia concerns the extent to which synesthetic experiences arise automatically. To shed light on this issue, we manipulated the stimulus onset asynchrony (SOA) in a synesthetic colour priming task (i.e., 0 ms, 200 ms, 1,000 ms). Results show that 200-ms presentations of synesthetic inducers produce reliable synesthetic colour priming at short SOAs. Based on this finding, we conclude that synesthesia is produced by fast-acting, automatic processes.
