Document Summary
Sensation: detection of physical energy by sense organs (eyes, ears, nose, skin, tongue). Sense organs relay info to the brain. Perception: brain"s interpretation of input from sense organs. Gives meaning and coherence to raw data. How stimuli are detected under different conditions. Signal to noise ratio- harder to detect a signal clearly as background noise increases. Response biases: hits and misses sin signal detection. Mcgurk effect: hearing audio of one syllable, while watching a video of someone articulating a different syllable, produces an experience of a third sound. Rubber hand illusion: sense of touch and sight can interact to produce a false perceptual experience. Experience of cross-model sensations by a small number of people. More common among children, fine arts students, musicians. Grapheme-colour synaesthesia: numbers associated with specific colours. Lexical-taste synaesthesia: words have taste associated with them. Paying attention to multiple sense modalities simultaneously. Bottom-up processing: construct a whole from its component parts. Moves from visual cortex to association cortex.
