FIGURAL AFTEREFFECT Meaning and
Definition
-
The figural aftereffect is a perceptual phenomenon characterized by the illusion of perceiving an object or pattern in a distorted or altered manner after sustained exposure to a specific visual stimulus. It refers to the perceptual bias that arises when an individual's visual system adapts to a particular stimulus, resulting in an altered perception of subsequent stimuli.
The figural aftereffect occurs due to the brain's ability to adapt to repeated visual inputs over time, which can cause neural adaptation and selective fatigue in the relevant neural pathways. This adaptation can lead to a perceptual shift or distortion in the perception of subsequent stimuli. For example, if a person views a pattern that consists of horizontal lines for an extended period, they may subsequently perceive vertical lines as being slanted or tilted in the opposite direction.
This phenomenon is often demonstrated through the use of visual illusions, such as the famous "tilted lines illusion" where exposure to tilted lines can cause a subsequent perception of vertical lines as tilted in the opposite direction due to the figural aftereffect. The effect is temporary and typically diminishes over time as the visual system readapts to the new stimuli.
Understanding the figural aftereffect is crucial in elucidating the complexities of the human visual system and revealing the brain's remarkable capacity to adapt and interpret visual stimuli. It has implications in various fields, including cognitive psychology, vision research, and neurology, and continues to be an essential tool for investigating the mechanisms underlying perception and cognition.

Etymology of FIGURAL AFTEREFFECT
The word "figural" is derived from the Latin word "figūrālis", which means "pertaining to form or figure". It is related to the Latin word "figūra", meaning "shape" or "figure". The term "aftereffect" is formed by combining the prefix "after-" (meaning "later" or "following") and the noun "effect", ultimately derived from the Latin word "effectus", which means "execution" or "accomplishment".
Therefore, the etymology of "Figural Aftereffect" suggests that it refers to the visual phenomenon that occurs after prolonged exposure to a particular visual stimulus, causing a subsequent perception or distortion of figures or shapes.
