Hearing Words and Seeing Colours: An Experimental Investigation of a Case of Synaesthesia

  title={Hearing Words and Seeing Colours: An Experimental Investigation of a Case of Synaesthesia},
  author={Simon Baron-Cohen and Maria A. Wyke and C Binnie},
  pages={761 - 767}
A case of ‘chromatic–lexical’ (colour–word) synaesthesia is described, and its genuineness confirmed using the criterion of stable cross-modality imagery across time. The synaesthesia could not be accounted for by a memory hypothesis, nor was it associated with any psychiatric condition. Further analysis did not identify any semantic relationship between real words and colours, but the colours of nonwords were determined by the colours of the individual letters. Numbers also had their own… 
Coloured Speech Perception: Is Synaesthesia what Happens when Modularity Breaks Down?
A study is presented in which nine subjects were tested who also reported having coloured hearing and confirmed the genuineness of these nine cases of chromatic–lexical synaesthesia, with some consistency found in the colours evoked by hearing specific letters, suggesting the condition has a neurological basis.
The physiology of coloured hearing. A PET activation study of colour-word synaesthesia.
The results suggest that colour-word synaesthesia may result from the activity of brain areas concerned with language and visual feature integration, as conscious visual experience appears to occur without activation of the primary visual cortex.
Unconscious priming eliminates automatic binding of colour and alphanumeric form in synaesthesia
It is concluded that automatic binding of colour and alphanumeric form in synaesthesia arises after initial processes of letter and digit recognition are complete and that synaesthetic experiences can be prevented despite substantial processing of the sensory stimuli that otherwise trigger them.
Neural correlates of imagined and synaesthetic colours
The experience of colour is a core element of human vision. Colours provide important symbolic and contextual information not conveyed by form alone. Moreover, the experience of colour can arise
Processing compound words: Evidence from synaesthesia
The results show the influence of implicit linguistic measures on synaesthetic colours, and support multiple/dual-route models of compound processing.
Anomalous perception in synaesthesia: A cognitive neuroscience perspective
The latest findings on synaesthesia are reviewed, and its possible genetic, neural and cognitive bases are considered, and a neurocognitive framework for understanding anomalous perceptual experiences is proposed.
The neural correlates of coloured music: A functional MRI investigation of auditory–visual synaesthesia
The results support the idea of the parietal cortex acting as sensory nexus area in auditory-visual synaesthesia, and as a common neural correlate for different types of synaesthetic.
Investigation into the underlying linguistic cues of Chinese synaesthesia
Synaesthesia is a neurological condition in which a sensory or cognitive stimulus consistently co-activates another sensory/cognitive quality, in addition to its usual qualities. For example,
A systematic , large-scale study of synaesthesia : implications for the role of early experience in lexical-colour associations
For individuals with synaesthesia, stimuli in one sensory modality elicit anomalous experiences in another modality. For example, the sound of a particular piano note may be ‘seen’ as a unique
Synesthesia: a colorful word with a touching sound?
Current methods for both assessing synesthesia and examining its psychological basis, including the “test-retest” procedure, online battery assessments, and behavioral experiments are reviewed and a set of markers are provided that aid in distinguishing synesthesia from other closely related psychological phenomena.


Synesthesia I. A review of major theories and their brain basis
It is the reality and vividness of the cross-modal percept that makes synesthesia quite interesting-even charming-in its apparent violation of the law of specific nerve energies.
Types of synaesthesia.
The main part of the paper deals with empirical instances of some of the theoretically possible types of synaesthesia, taken from the literature, from reports of naturally occurring synaesthetic, and from a series of experiments with mescaline.

I found it extraordinarily difficult to fathom what experimental subjects were perceiving in the color-hearing experiments, and an investigation of subliminal auditory activity alerted me to this problem of intersensory perception.
