Illusion: when the image we perceive is not the reality of it. Sensation: the detection of physical energy by our sensory organs, which relay the info to our brains. Perception: the brain"s interpretation of the sensory inputs. Making it from just the sensations we feel into a picture or thing we know. Filling is the process of making a picture whole. Transduction: the process by which the nervous system converts an external stimuli; like light or sound, into electrical signals within neurons. A specific sense receptor transduces a specific stimuli. Sensory adaption: the 1st time we detect a stimuli, the activation is the greatest. Psychophysics: the study of how we perceive sensory stimuli based on their characteristics. Absolute threshold: lowest level of stimuli we can detect. Just noticeable difference: the smallest change in the intensity of a stimuli that we can detect. Weber"s law believes there is a constant proportional relationship between.
