5.1 Sensation versus PerceptionReview Questions________ refers to the minimum amount of stimulus energy requiredto be detected 50% of thetime.a.absolute thresholdb.difference thresholdc.just noticeable differenced.transduction
Decreased sensitivity to an unchanging stimulus is known as ________.
________ involves the conversion of sensory stimulus energy into neural impulses.
________ occurs when sensory information is organized, interpreted, and consciously experienced.
Critical Thinking QuestionNot everything that is sensed is perceived. Do you think there could ever be a case wheresomething could be perceived without being sensed?Please generate a novel example of how just noticeable difference can change as a function ofstimulus intensity.Yes, statements regarding extrasensory perception are an example of this. Another example is thephantom limb phenomena, which amputees experience.One example is the identification of weight disparities. If two persons each hold a basic standardenvelope, one containing a coin and the other empty, the weight difference between the two iseasily discernible. However, if these two envelopes of identical weight are put inside a textbook,determining which one is heavier becomes considerably more difficult.
Personal Application QuestionThink about a time when you failed to notice something around you because your attention wasfocused elsewhere. If someone pointed it out, were you surprised that you hadn’t noticed it rightaway?
