Document Summary

Synesthesia: mixing of the senses people who experience sounds as colours or tastes as touch sensations that have different shapes. The five stages that constitute the process of sensory processing and perception of information: Receptors translate stimulus properties into nerve impulses (transduction) Stimulus features are reconstructed into neural representation and is compared with previously stored information in brain. Matching process results in recognition and interpretation of stimuli (perception) Sensation: the stimulus-detection process by which our sense organs respond to and translate environmental stimuli into nerve impulses that are sent to the brain. Perception: making sense of what our senses tell us, the active process of organizing this stimulus input and giving it meaning. Psychophysics: studies relations between the physical characteristics of stimuli and sensory capabilities. What is the softest sound or the weakest salt solution that humans can detect: differences between stimuli. Absolute threshold: the lowest level of stimulation that a person can detect correctly 50 percent of the time.
