Sensation and Perception Remarkably, using just five basic senses, our brains translate simple external stimuli (e.g. light and sound waves) into unique and vivid perceptual experiences enabling us to interact with our surrounding physical reality. Focusing primarily on the underlying mechanisms of vision and audition, we will explore how our brains construct detailed representations of our world. Throughout these explorations, we will identify perceptual limitations and investigate how mental processes such as attention and emotion affect our perceptions. We will review recent scientific articles and conduct experiments.
