Vision Transduction Wavelength conversion of one form of energy to another in sensation, transforming of stimulus energies into neural impulses Wavelength the distance from the peak of one wave to the peak of the next

Body Position and Movement Kinesthesis the system for sensing the position and movement of individual body parts Vestibular Sense the sense of body movement and position including the sense of balance

Chapter 6

Perception Selective Attention focus of conscious awareness on a particular stimulus Cocktail party effect

Perceptual Organization: Gestalt Visual Capture tendency for vision to dominate the other senses Gestalt--an organized whole tendency to integrate pieces of information into meaningful wholes

Perceptual Organization: Gestalt Grouping the perceptual tendency to organize stimuli into coherent groups Grouping Principles proximity--group nearby figures together similarity--group figures that are similar continuity--perceive continuous patterns closure--fill in gaps connectedness--spots, lines, and areas are seen as unit when connected

Perceptual Organization Figure and Ground--organization of the visual field into objects (figures) that stand out from their surroundings (ground)

Perceptual Organization Depth Perception ability to see objects in three dimensions allows us to judge distance Binocular cues retinal disparity images from the two eyes differ closer the object, the larger the disparity convergence neuromuscular cue two eyes move inward for near objects

Perceptual Organization: Depth Perception Visual Cliff

Perceptual Organization: Depth Perception Monocular Cues relative size smaller image is more distant interposition closer object blocks distant object relative clarity hazy object seen as more distant texture coarse --> close fine --> distant

Perceptual Organization: Depth Perception Interposition

If you remove other objects from your field of vision – objects appear to change size. Looking at a person standing at the end of a tunnel. Use other data in the environment to judge things. If you run into Wheeler at the mall…. You may not recognize her at first  Context Effects

Is There Extrasensory Perception? controversial claim that perception can occur apart from sensory input telepathy clairvoyance Precognition Parapsychology the study of paranormal phenomena ESP psychokinesis

Perception and the Human Factor Human Factors Psychology explores how people and machines interact explores how machine and physical environments can be adapted to human behaviors
