Constructing priors in synesthesia

Constructing second-order data dependent probability matching priors from first-order probability matching priors

Executive functions in synesthesia.

In grapheme-color synesthesia, a number or letter can evoke two different and possibly conflicting (real and synesthetic) color sensations at the same time. In this study, we investigate the relationship between synesthesia and executive control functions. First, no general skill differences were obtained between synesthetes and non-synesthetes in classic executive control paradigms. Furthermor...

Color Synesthesia

Synesthesia is a condition in which stimulation in one sensory or cognitive stream involuntarily, or automatically, leads to associated internal or external (illusory or hallucinatory) experiences in a second unstimulated sensory or cognitive system [1–9]. Although most cases of synesthesia are developmental and run in families, acquired cases have also been reported following traumatic brain i...

Validating a standardised test battery for synesthesia: Does the Synesthesia Battery reliably detect synesthesia?

Synesthesia is a neurological condition that gives rise to unusual secondary sensations (e.g., reading letters might trigger the experience of colour). Testing the consistency of these sensations over long time intervals is the behavioural gold standard assessment for detecting synesthesia (e.g., Simner, Mulvenna et al., 2006). In 2007 however, Eagleman and colleagues presented an online 'Synes...

Acquired Synesthesia in Retinitis Pigmentosa

Patient PH developed retinitis pigmentosa in childhood and progressively lost his vision until he became completely blind at 40 years old. At age 42, he started experiencing vivid ‘synesthesia’; tactile stimuli on the hand evoked a vivid visual sensation of ‘movement’, ‘expansion’ or ‘jumping’. Intriguingly, the synesthesia was much more vivid when the hand was in front of the face rather than ...
