Mean quick literally mixing of the senses , colours or tastes as touch sensations that have different shapes. Sensation: stimulus is received by sensory receptors, receptors translate stimulus properties into nerve impulse (transduction) 3: stimulus features are reconstructed into neural representation, neural representation is compared with previously stored information in. Feature detectors analyze stimulus features brain: matching process results in recognition of stimuli. Sensation: is the stimulus- detection process by which our sense organs respond to and translate environmental stimuli into nerve impulses that are sent to our brain. Perception: making sense of what our sense tell us- is the active process of organizing this stimulus input and giving it meaning.
