What is Acquired Synesthesia?

  • Acquired Synesthesia: Synesthesia is a relatively common perceptual anomaly where a stimulus of one of the senses (e.g. hearing) results in an experience or sensation in another sensory modality or an unusual perception in the same sensory modality. The neurological anomaly is involuntary and there are a range of theories that attempt to explain the etiology of the condition. Synesthesia may be idiopathic (developmental) or acquired e.g. the use of certain drugs such as LSD may produce synesthesia. There is a wide range of possible perceptual anomalies. Other examples include:
    • perceiving months or weekdays as a color
    • perceiving months or weekdays as a particular spatial location e.g. July is always located 2 metres in front of you
    • perceiving a sound as a particular color e.g. a microwave beep is perceived as orange
    • particular words can trigger a specific taste in the mouth
    • smelling things can result in the sensation of touch - e.g. smelling a flower can feel like touching cold glass
    • pain perceived as a particular color
    • and many others.
