PSYC 1101 Chapter Notes - Chapter 4: Moon Illusion, Kurt Koffka, Olfaction
Document Summary
Transduction: converting external signals into a language the nervous system can understand. Sense receptor: specialized cell that transduces a specific stimulus. Sensory adaptation: response to a stimulus declines after first activation. Gustav fechner: absolute threshold: lowest level of stimulus we can detect, weber"s law: constant relationship between jnd and original stimulus intensity. Just noticeable difference: smallest change in stimulus that we can detect. Signal detection theory: david green and john swets: how we detect stimuli under certain conditions; signal-to-noise ratio, response biases. Johannes muller: doctrine of specific nerve energies the sensation we experience is determined by the nature of the receptor, not the stimulus: mcgurk effect: we integrate visual and auditory information when processing language. Rubber hand illusion : synesthesia: sir francis galton; rare condition in which people experience cross-modal sensations (hearing sounds when they see colors) Perceptual hypothesis: perceptual set: formed when our expectations influence our perceptions (top-down)
