Psychology 1101 Chapter 4 Page 130 Visual agnosia-an inability to recognize objects through sight. As Dr. P’s case illustrates,without effective processing of sensory input,our  familiar world can become a chaos of bewildering sensations. Sensation-stimulation of sense organs.This involves the absorption of energy, such  as light or sound waves,by sensory organs,such as the eyes and ears. Perception-selection,organization,and interpretation of  sensory input.This  involves organizing and translating sensory input into something meaningful. Psychophysics-the study of how physical stimuli are translated into psychological  experience. Sensation begins with a stimulus Page 131 Threshold-dividing point between energy levels that do and do not have a  detectable effect. Absolute threshold-minimum stimulus intensity that an organism can detect Absolute thresholds define the boundaries of an organism’s sensory capabilities. A just noticeable difference(JND) is the smallest difference in stimulus intensity  that a specific sense can detect. In general, as stimuli increase in magnitude,the JND between them becomes  larger.

Signal-detection theory proposes that the detection of stimuli involves decision  processes as well as sensory processes,which are both influenced by a variety of  factors besides stimulus intensity. Page 132
