People with synaesthesia show an enhanced memory relative to demographically matched controls. The most obvious explanation for this is that the 'extra' perceptual experiences lead to richer encoding and retrieval opportunities of stimuli which induce synaesthesia (typically verbal stimuli). Although there is some evidence for this, it is unlikely to be the whole explanation. For instance, not all stimuli which trigger synaesthesia are better remembered (e.g., digit span) and some stimuli which do not trigger synaesthesia are better remembered. In fact, synaesthetes tend to have better visual memory than verbal memory. We suggest that enhanced memory in synaesthesia is linked to wider changes in cognitive systems at the interface of perception and memory and link this to recent findings in the neuroscience of memory.
联觉者相对于人口统计学匹配的对照组表现出增强的记忆力。对于这种现象，最明显的解释是，这种“额外”的知觉体验导致了对引发联觉的刺激（通常是言语刺激）更丰富的编码和检索机会。尽管有一些证据支持这一点，但它不太可能是全部解释。例如，并非所有引发联觉的刺激都能被更好地记住（例如，数字跨度），而一些不会引发联觉的刺激反而能被更好地记住。事实上，联觉者往往具有比言语记忆更好的视觉记忆。我们认为，联觉中的增强记忆与知觉和记忆界面的认知系统的更广泛变化有关，并将其与记忆神经科学的最新发现联系起来。
