Synaesthesia: The Prevalence of Atypical Cross-Modal Experiences
The first test of synaesthesia prevalence with sampling that does not rely on self-referral, and which uses objective tests to establish genuineness is presented, and it is suggested that female biases reported earlier likely arose from (or were exaggerated by) sex differences in self-disclosure.
Somatosensory activations during the observation of touch and a case of vision-touch synaesthesia.
The results suggest that, in C, the mirror system for touch is overactive, above the threshold for conscious tactile perception.
Sound-Colour Synaesthesia: to What Extent Does it Use Cross-Modal Mechanisms Common to us All?
The results support the conclusion that this form of synaesthesia recruits some of the same mechanisms used in normal cross-modal perception rather than using direct, privileged pathways between unimmodal auditory and unimodal visual areas that are absent in most other adults.
Non-random associations of graphemes to colours in synaesthetic and non-synaesthetic populations
It is shown that biases exist in the associations of letters with colours across individuals both with and without grapheme-colour synaesthesia, and that graphemed people tend to associate higher frequency graphemes with higher frequency colour terms.
Mirror-touch synesthesia is linked with empathy
Evidence for the existence of 'mirror-touch' synesthesia is provided and it is shown that it correlates with heightened empathic ability, consistent with the notion that the authors empathize with others through a process of simulation.
What is the relationship between synaesthesia and visuo-spatial number forms?
The presence of synaesthetic colour sensations enhances the tendency to explicitly represent numbers in a visuo-spatial format although the two symptoms may nevertheless be logically independent (i.e. it is possible to have number forms without colour, and coloured numbers without forms).
Prevalence, characteristics and a neurocognitive model of mirror-touch synaesthesia
The first study on the prevalence of so-called ‘mirror-touch synaesthesia’ indicates that it is just as common, if not more common than some of the more frequently studied varieties of synaesthetic, and proposes a neurocognitive model to account for these characteristics.

The results suggest that the memory enhancement found in synaesthetes is related to an enhanced retention of colour in both synaesthetic and nonsynaesthetic situations, which may account for the fact that synaesthesia associations, once formed, remain highly consistent.
Visual experiences in the blind induced by an auditory sensory substitution device
The phenomenology of two blind users of a sensory substitution device - "The vOICe" - that converts visual images to auditory signals is described and may constitute an example of acquired synaesthesia.
Lexical-gustatory synaesthesia: linguistic and conceptual factors
The results suggest that synaesthesia does not simply reflect innate connections from one perceptual system to another, but that it can be mediated and/or influenced by a symbolic/conceptual level of representation.
