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. These phenomena have been used to investigate how bottom-up sensory and top-down cognitive processes interact to determine perceptual awareness. Individuals vary considerably in their switching patterns, and these patterns can be idiosyncratic. Perceptual switching has been related to cognitive flexibility and the tendency to change one’s mind. This raises the interesting question as to 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.
You will explore the relationships between cognitive and perceptual flexibility and their development through childhood, and investigate the neural correlates of perceptual flexibility and creative thinking.
