Document Summary
Vision: differentiate between sensation and perception and differentiate between bottom-up and top-down processing and give examples of each. Sensation: detection of stimuli by sense organs. Transduction: transforming sensory input (light, sound, waves, etc. ) into neural impulses our brain can interpret: specific types of specialized cell/sense receptor transduce a specific stimulus, requires sensory coding. Different stimuli are connected to different stimuli. Different stimuli result in different firing rates (often representing intensity) Receive sensory stimuli using specialized receptors: 2. Bottom up processing: detect specific features of stimulus combine specific features into more complex forms recognize stimulus: starts with raw info (experiences and expectations), includes some low-level analysis then forms a meaningful concept, building schema. Perception: formation of a mental representation of these stimuli (organization and interpretation of input, recognize meaningful objects and events) Allows us to assemble these signals into something meaningful. Parallel processing: ability to attend to many sense modalities simultaneously: bottom-up processing.
