Chapter 3: The Psychophysics of Sensation

Chapter 3 examines the attributes of an external stimulus, which the brain collects and models to construct a sensation. An important aspect of this process is the sensory system's filtering capacity, which removes extraneous and irrelevant information from the modeled information. The response mechanisms of all five senses are discussed to establish the practice of viewing the discipline (psychophysics) from multiple perspectives (senses). The differences in multiple perspectives on the same data is compiled into a model of the attributes to which the brain attends to engage with a sensation.
