associative synesthesia: feeling a very strong and involuntary connection between the stimulus and the sense that it triggers; For example, in chromesthesia (sound to color), a projector may hear a trumpet, and see an orange triangle in space, while an associator might hear a trumpet, and think very strongly that it sounds "orange".
Alternatively, synesthesia may arise through "disinhibited feedback" or a reduction in the amount of inhibition along feedback pathways (Grossenbacher & Lovelace 2001).It is well established that information not only travels from the primary sensory areas to association areas such as the parietal lobe or the limbic system, but also travels back in the opposite direction, from "higher order ...
Synesthesia is when input from one sense triggers the brain to associate it with another sensory experience. Dr. Hersh: Synesthesia occurs when more than one sense is experienced simultaneously ...
Sound-color synesthesia is far more common than color-sound synesthesia, although there are reported cases where sounds and colors activate bidirectionally. One individual sees colors when she hears sounds and also hears sounds when she sees colors. [7] This type of synesthesia interferes greatly with daily life.
His personal life is described as being lived in a "haze", and eventually he was confined to a mental institution because of the burden of his exceptional abilities. But S is a rare exception and drawbacks are not normally associated with the acquisition of an exceptional memory by using synesthesia mnemonically. [48]
Mirror-touch synesthesia is a rare condition which causes individuals to experience a similar sensation in the same part or opposite part of the body (such as touch) that another person feels. For example, if someone with this condition were to observe someone touching their cheek , they would feel the same sensation on their own cheek.
A common example of synesthesia is the association between graphemes and colors, usually referred to as grapheme–color synesthesia. Here, letters of the alphabet are associated with vivid experiences of color. Studies have indicated that the perceived color is context-dependent and is determined by the extracted meaning of a stimulus.
Examples include synesthesia, sensory substitution and the McGurk effect, in which vision and hearing interact in speech perception. Crossmodal perception, crossmodal integration and cross modal plasticity of the human brain are increasingly studied in neuroscience to gain a better understanding of the large-scale and long-term properties of ...
