PSC 1 Lecture Notes - Lecture 5: Milgram Experiment, Reinforcement, Self-Actualization
Document Summary
Sensory: detection and transmission of external signals to the brain through sensory coding. Sensory coding: how external signals get transmitted into neural signals. Perception: how we organize, process, and interpret signals. Bottom up processing:perception of the physical properties of an object. Top down processing: using background knowledge and context to interpret sensory signals. Absolute threshold: the minimum amount of an stimuli you need to experience a stimuli. Difference threshold: the minimum amount of change you need. Sensory adaptation: when your senses adapt to a stimuli so its to detect a change in 2 stimuli sensitivity to it is reduced. Color perception: has 3 dimensions which are. Saturation: how much gray there is mixed in a color. Brightness: how light or dark a color appears. Rods: good for low light and just motion. Distribution in the retina: behind the ganglion cells. Trichromatic theory: color perception is based on 3 colors.
