Our perceptual system accepts various sensory information that changes from time to time by selecting, interpreting, and inferencing meaningful information. This process is profound to our perception in which certain information will be chosen and consciously perceived. One method we are using to study the process of visual awareness is binocular rivalry, in which the two dissimilar images presented each eye switch between two competing states of awareness (see Dr. Randolph Blake’s website for more information: From low-level visual information such as contrast, motion, and shape to complex high-level information like music reading and facial stimulation with various social meanings, we aim to figure out how these various types of information relate to human perceptual inference and visual awareness processes.


We have been studying perceptual inference and visual awareness using low-level stimuli and high-level stimuli.
