Synaesthesia – some thoughts and questions

 

Synaesthesia is a perceptual phenomenon where people seem to have atypical experiential sensory properties in one or more perceptual categories (e.g. that letter shapes induce a perceptual colour quality). The prevalence of synaesthesia have varied from the early studies and until today where there is a consensus that this is a fairly common condition affecting approximately 1 in 23 og healthy people. Various explanations on the phenomenon (e.g. genetics) have been proposen, but synaesthesia may in fact just be an instance of the perceptual variations that exists between observers. I this talk I will try and argue for some of the perceptual phenomena that suggest that perceptual strategies may vary to a high degree between individuals and finally I will also try and emphasise some of the large questions that still challenge our understanding of synaesthesia.     

Measuring priority in visual attention and working memory with EEG

Our visual system is confronted with more stimuli it can process at any given moment. Attention allows the selection of a subset of the incoming information to optimally use the limited resources. Working memory allows the maintenance of selected stimuli over short periods of time. Which factors determine the visual priority in attention and working memory? I addressed this question with electroencephalography (EEG) because this methods provides precise neural markers of attention deployment and working memory maintenance. In this talk I will present evidence of how various factors such as physical salience, current goals, emotional content, reward or associative learning affect the visual priority in attention and WM.
