Sensation is when we detect physical energy (stimuli). Perception is when we select & organize these sensations. They use transduction to take in stimuli then convert it into neural activity. Sensory receptors are specialized neurons that can be stimulated by the. Retina of eyes hair cells in inner ear. Difference threshold (just noticeable difference): perceiving the change of a: sensory thresholds stimulus. Minimum stimulation needed to detect a difference in stimulus 50% of time. (stimulus changes) stimulation 50% of the time (same stimulus) Absolute threshold: minimum stimulation needed to detect a particular. Habitation: tendency for the brain to stop attending to constant, unchanging information. Sensory adaptation: tendency of sensory receptors to become less responsive to a stimulus that is changing. Habitation is when the stimulus is still being sensed, but the brain begins to ignore them. But sensory adaptation is when the receptors become less responsive to stimulus.
