McConnelsville, Ohio, 27 January ; d. Ithaca, New York11 Decemberpsychology, perception, vision, ecological psychology, perception-action, epistemology Gibson was an innovative twentieth-century experimental psychologist whose work focused primarily on visual perception of the everyday world. His research and theoretical contributions over five decades culminated in a highly original perspective, the ecological approach to perceiving. This approach is unique in providing theoretical grounds and empirical support for the epistemological position of direct realism, which is the view that individuals perceive the environment directly.
Psychologists assess the acuity of our senses by measuring the absolute threshold and the difference threshold and by applying signal detection theory. Sensory adaptation is the decrease in sensitivity to an unchanging stimulus.
Babies are born with all the Kinesthesis involves sensory abilities and some perceptual skills, which develop and become more sensitive over time.
Vision The sense of vision depends on light, which is a kind of electromagnetic radiation emitted by the sun, stars, fire, and lightbulbs. We experience light as color, brightness, and saturation, which depend respectively on wavelength, amplitude, and complexity of light waves.
The eye is composed of the cornea, the iris, the pupil, the lens, the retina, and the fovea. The lens adjusts its shape to focus light from objects that are near or far away in a process called accommodation.
Dark and light adaptation are processes by which receptor cells sensitize and desensitize to light, respectively.
The retina has millions of photoreceptor cells called rods and cones. Rods and cones connect via synapses to bipolar neurons, which connect to ganglion cells. The axons of the ganglion cells make up the optic nerve, which connects to the eye at the optic disk, also called the blind spot.
After being processed in the brain, visual signals reach the primary visual cortex, where feature detectors respond to the signals. Color is a psychological experience created when the eyes and the brain interpret light. Trichromatic theory, or the Young-Helmholtz theory, states that there are three types of cones in the retina, which are sensitive to light of different wavelengths corresponding to red, green, or blue.
This theory accounts for color blindness. The opponent process theory states that receptors act in opposite ways to wavelengths associated with three pairs of colors: The theory accounts for the perception of four primary colors.

Shares Precognition involves the theory that people are able to think of an event before it happens. It is still considered supernatural—a form of clairvoyance—and not generally accepted as possible.
It also accounts for afterimages, or colors perceived after other complementary colors are removed. An example is the phi phenomenon, in which an illusion of movement occurs when images are presented in a series, one after another.
Gestalt psychologists describe principles people use to organize vision into units that make sense, including: Binocular and monocular cues enable people to determine distance from an object.
Perceptual constancy is the ability to recognize that an object is the same when it produces different images on the retina. Visual constancies relate to shape, size, brightness, color, and location.
Visual illusions are misinterpretations of visual stimuli. Selective attention is the ability to focus on some pieces of sensory information and ignore others.
