联觉的发展与习得

联觉具有基因遗传性, 基因遗传在决定联觉中起到重要作用, 但并不意味着基因遗传就是决定联觉的唯一因素, 联觉具有在后期发展的可能, 并且这种发展呈现倒U形曲线。既然联觉是发展的, 那么联觉可否通过训练习得呢？目前不少研究对非联觉者进行了配对关联训练, 发现训练后的非联觉者具有类似于联觉者的表现, 也发现训练后的非联觉者与真正的联觉者具有一定的差异。但目前研究还没有直接或强有力的证据表明训练所致的配对关联就是一种联觉, 训练后的非联觉者就能变成联觉者。相反地, 越来越多的证据显示非联觉者经过配对关联训练后可能无法成为真正的联觉者。

The Development and Acquisition of synesthesia

Synaesthesia seems to have a genetic basis and runs in families, the genetic predisposition play a important role in determining synesthesia, but it doesn’t mean that the gene is the only factor to determine synesthesia. Current studies have showed that the development of synaesthesia in different age groups, and its development follows the inverted U shape curve. A related question with developmental aspects of synesthesia is: synesthesia can be learned? Some researches have been carried out the paired-association training to non-synesthetes, but there are no direct or strong evidences that the paired-association obtained from training is a kind of synesthesia. On the contrary, more and more evidences indicate that non-synesthetes after the paired-association training can not become a true synesthetes.
