Document Summary

Chapter 5: sensation and perception synesthesia: a condition where stimuli are experienced by more than one sense. Literally means mixing of the senses can experience sounds as colours or tastes as touch sensations that have different shapes. Sensory receptors must translate information into nerve impulses. Then, specialized neurons break down and analyze the specific features of the stimuli. At the next stage, these numerous stimulus pieces are reconstructed into a neural representation that is then compared with our knowledge of what particular objects look, smell, or feel like. 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. The difference threshold: the smallest difference between two stimuli that ppl can perceive 50% of the time also called the just noticeable difference (jnd)
