Psychology Terms - Accommodation
1. The voluntary or involuntary modification of the curvature of the crystalline lens of the eye to maintain image focus on the fovea as the distance to the viewed object varies; specifically, it serves as one of the monocular cues for visual depth perception, with the curvature degree of the lenses conveying information regarding the distances of objects projected onto the retinas. Also referred to as visual accommodation. Refer to accommodation reflex, dark focus, far point, near point, Purkinje–Sanson picture, and range of accommodation. 2. In the works of Swiss psychologist Jean Piaget (1896–1980) and his adherents, a type of adaptation is described wherein psychological structures or processes are altered to accommodate the evolving requirements of the environment, exemplified by an infant adjusting its perceptual processes and behavioral repertoire in response to the introduction of a novel toy into its surroundings. Refer to equilibration as well. Contrast assimilation (2). 3. A diminished likelihood of a neuron generating a *action potential, with the decreased responsiveness resulting from repetitive activation.
