PSYA01H3 Chapter Notes - Chapter 4: Detection Theory, Neural Adaptation, Psychophysics
Document Summary
What is the difference between sensation and perception, what are the principles of guided perception. Sensation-process of detecting external events wit sense organs and turning those stimuli into neural signals. Perception- involves attending to, organizing, and interpreting the stimuli we sense. Transduction occurs when specialized receptors transform the physical energy of the outside world into neural impulses. This gives rise to our internal representation of the world. It is not the original sensory input that is most important for generating our perceptions but, rather, the brain area that processes this information. Doctrine of specific nerve energies was first proposed by m ller and states that the different senses are seperated in the brain. Orienting response describes how we quickly shift our attention to stimuli that signal a change in our sensory world. Sensory adaptation is the reduction of activity in sensory receptors with repeated exposure to a stimulus (over time and such)
