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 are related to other measures of cognition, such as executive functions, creativity or personality. Moreover, we want to investigate whether perceptual switching manifests similar or different patterns in children and whether executive functions and creativity are associated with perceptual switching. Transcranial magnetic stimulation will be used to determine whether parietal cortex is causally involved in both visual and auditory multistability.
