Colour–Grapheme Synesthesia Affects Binocular Vision
In colour-grapheme synesthesia, non-coloured graphemes are perceived as being inherently coloured. In recent years, it is debated whether visual processing of synesthesia-inducing achromatic graphemes is similar to that of chromatic graphemes. Here, we exploit the phenomenon of binocular rivalry in which incompatible images presented dichoptically compete for conscious expression. Importantly, ...
متن کاملDefining (trained) grapheme-color synesthesia
There is a current debate over the possibility and validity of synesthesia training experiments (Deroy and Spence, 2013; Rothen and Meier, 2014). In order to test whether a trainee should be considered to have acquired a trained form of synesthesia, a precise definition and specific diagnostic criteria of synesthesia are necessary. There is currently not one specific checklist available includi...
متن کاملNeural correlates of induced grapheme-color synesthesia
Synesthesia is a perceptual anomaly where stimulation of one sensory modality elicits sensation of a concurrent stimulus from another modality. A previous study has shown that it is possible to establish such an alteration of perception in nonsynesthetes by means of hypnotic suggestion. We tried to extend these results to gain further insight in the underlying neural processes using magnetoence...
متن کاملSecond-order mappings in grapheme-color synesthesia.
Typically, the search for order in grapheme-color synesthesia has been conducted by looking at the frequency of certain letter-color associations. Here, we report stronger associations when second-order similarity mappings are examined--specifically, mappings between the synesthetic colors of letters and letter shape, frequency, and position in the alphabet. The analyses demonstrate that these ...
متن کاملGrapheme learning and grapheme-color synesthesia: toward a comprehensive model of grapheme-color association
Recent progress in grapheme-color synesthesia research has revealed that certain regularities, as well as individual differences, figure into grapheme-color associations. Although several factors are known to regulate grapheme-color associations, the impact of factors, including their interrelationships, on synesthesia remains unclear. We investigated determinants of synesthetic color for graph...
