Individual differences in visual and auditory bistability

Investigate the relationships between switching rates in multistable perception, cognitive abilities, creativity and personality.

Disciplines:

    • Experimental psychology
    • developmental psychology
    • neuroscience

When viewing or listening to ambiguous stimuli (stimuli with more than one possible interpretation) people experience changes in perceptual awareness in the absence of the stimulus change. Perceptual multistability is a useful tool for investigating the neural correlates of perceptual awareness without stimulus confounds; people switch between different perceptions of the same unchanging sensory signal.  Perceptual switching has been related to cognitive flexibility and the tendency to change one’s mind.

The aim of this project is to see whether perceptual switching patterns correspond to other measures of cognitive style, such as creativity or tolerance for monotony and at what age these different predispositions can be detected.Moreover, we will examine the neurocoletates of switching.
