The document discusses sensory perception and the five senses. It explains that the sensory system processes sensory information through sight, touch, hearing, smell, and taste. Sensory receptors allow individuals to gather information about their environment. The brain is deeply connected to sensory data, creating memories. Sensory perception helps explain why some born without a sense can later regain it through technology like cochlear implants. There are reasons to trust or distrust sensory data based on feedback from the environment.
