Document Summary

First chapter provides an introduction to sorts of questions and the methods that researchers have developed to find answers to them. Your own sensory experience is directly accessible only to you. Sensation ability to detect a stimulus and perhaps turn that detection into a private experience. Perception act of giving meaning to a detected sensation. S and p are central to mental life. We can demonstrate that different people do, sometimes, inhabit different sensory worlds. Method 3: signal detection theory - measuring difficult decisions. Perceptual decisions (is the tumor benign or not?) have real consequences. This will introduce the ways in which sensory receptors and nerves undergird your perceptual experience. Method 5: neuroimaging - an image of the mind. Binocular rivalry when two images compete to dominate your perception. Modern brain-imaging techniques enable us to see traces of that experience as it takes place in the brain. Gustav fechner sometimes considered the true founder of experimental psychology.
