Document Summary

Chapter outline: a few interesting findings , basics of sensation and perception, the chemical senses: smell and taste, the tactile or cutaneous senses: touch, pressure, pain, vibration, the auditory sense: hearing, the visual sense: sight. Synesthesia: a subjective experience of an aspect of a sense other than the one being stimulated. Brain regions for different sensory modalities cross-activate each other. Examples include : the basketball tracking task, door study. Sensation the act of using our sensory systems to detect environmental stimuli. Sensory receptor cells specialized cells that convert a specific form of environmental stimuli into neural impulses. Sensory transduction the process of converting a specific form of sensory data into a neural impulse that our brain can read. Absolute threshold is the smallest amount of a stimulus that one can detect. In other words, this is the difference between sensing and not sensing . Just noticeable difference (jnd): the minimal change in a stimulus that can just barely be detected.
