Important concepts to know – Module 1The concepts listed below are the most important ones for you to understand in this module. You can use this list to help you with notetaking while you watch the videos. Unit 1 – What is perception Are there really five senses? What is sensation? What is perception? Neural transduction: receptors, transduction and neural response What is phenomenology? Aristotle and the five senses Thomas Young: colors are coded by three different kinds of nerve fibers Johannes Mueller: doctrine of specific nerve energies Von Helmholtz: o perception is constructed from both senses and cognitive processeso unconscious inferenceo three basic color receptors (like Young) Hering: colors are perceived through 2 pairs of opposing colors (four primary colors, not three)  Weber’s Law: the just-noticeable difference between two stimuli is related to the magnitude or strength of the stimuli. Fechner: father of psychophysics, the study of the relation between physical stimuli and the perception they elicit. Fechner’s law: sensation is a logarithmic function of physical intensity Gestalt psychology: The whole is larger than the sum of its parts Gestalt laws:o Law of Proximityo Law of Common Fateo Law of Closureo Law of Similarityo Law of Good Continuation Gibson and Direct Perception Information Processing Approach Computational Approach Neuroscience in Sensation and Perception (brain organization) Methodologies in Neuroscience:o Microelectrodeo Neurophysiology: agnosia, prosopagnosiao Electroencephalography (EEG)o Functional MRI (fMRI)Unit 2 – Research Methodology What is a Psychophysical Scale Absolute Threshold Method of Limits (using crossover points) Method of Constant Stimuli (50% detection) Method of Adjustment (observer adjusts) Sensitivity Magnitude Estimation Steven’s Power Law Catch Trials and Their Use Signal Detection Theoryo Criteriono d primeo Hito Misso False Alarmo Correct Rejectiono Receiver Operating Characteristic Changes in Criterion Differences in Sensitivity (d
