Document Summary
The first chapter in most academic textbooks forms the foundation for material to be presented in later chapters and the fundamentals of sensory perception is not different in this respect. Much of what you learn in this chapter will be applied to specific sensory systems in later chapters. In this chapter, you will come to appreciate the various psychophysical methods that have been developed and how they are used to understand our sensory perceptual systems. As such, the focus in this chapter is on gaining an understanding of the basic relationship between our perceptual experience and the physical stimulus that acts upon a sensory system to produce the perception. You will learn about classical methods of psychophysics, including the methods of adjustment, limits, and contant stimuli, highlighting the work of fechner and weber. Weber"s law deals with how much additional stimulus intensity is needed for a subject to just notice a difference in the stimulus intensity.
