Synesthesia  is characterized  by consistent extra perceptual experiences in response to normal sensory input. Recent studies provide evidence for a specific profile of enhanced memory performance in synesthesia, but focus exclusively on explicit memory paradigms for which the learned content is consciously accessible. In this study, for the first time, we demonstrate with an implicit memory pa...

Richard Cytowic has done considerable service to the scientific study of synesthesia, conducting important research and publishing two recent books on the subject. The study of synesthesia raises interesting questions about scientific method, both because of the negative reception it received initially--often being viewed as tainted by a reliance upon introspective reports--and because of the c...

Synesthesia is a condition that affects an individual’s conscious perception of the world. Individuals with this disorder vary greatly, but have in common the phenomenon of cross-modal perceptions. For example, grapheme-color synesthetes perceive color when presented with graphemes, such as letters and numbers. In this review, we investigate this phenomenon further in order to evaluate the plau...

In this paper the research on a person declaring synesthetic abilities will be presented. According to the current state of knowledge synesthesia activates additional cortical fields in the brain which can be found in the EEG. The research was conducted using an EGI-EEG system (Electrical Geodesic Inc., Eugene, Oregon, USA) with the GeoSource software. GeoSource is a tool that implements the al...

Synesthesia is a hereditary, neurological condition in which a wide range of common stimuli (e.g., letters, sounds, flavors) trigger unexpected secondary sensations, for example, synesthetes listening to music might see colors in addition to hearing sounds (Ward et al., 2006; see Simner and Hubbard, 2013, for review). Current explanations of synesthesia posit structural and/or functional differ...

Synaesthesia may facilitate the expression of creativity. Therefore synaesthetes may be more common in the world of creative art. To test this possibility, we used behavioural and phenomenological measures to assess the existence of grapheme-colour synaesthesia in a sample of art students (N = 99) and a control sample (N = 96). We found a prevalence of about 7% in the former and about 2% in the...

People with sequence-space synesthesia (SSS) report stable visuo-spatial forms corresponding to numbers, days, and months (amongst others). This type of synesthesia has intrigued scientists for over 130 years but the lack of an agreed upon tool for assessing it has held back research on this phenomenon. The present study builds on previous tests by measuring the consistency of spatial locations...
