KINESTHETIC AFTEREFFECT (KAE): Definition, History, and Further Reading
The kinesesthetic aftereffect (KAE) is a phenomenon in which the perception of a stimulus is altered by a prior experience. It is typically observed as an adaptation to a movement stimulus, such as a motion or force, where the aftereffect is a change in the perceived direction or intensity of the stimulus. KAE is thought to be a form of sensorimotor plasticity and is used as a measure of perceptual learning.
The concept of KAE can be traced back to the work of Fechner in the mid-19th century, who observed that when a repetitive stimulus was presented, people experienced a change in the perceived intensity of the stimulus. In the early 20th century, researchers sought to explain this phenomenon, and the term KAE was first used by Berthoz in 1967 to describe the phenomenon of motion adaptation. Subsequent research has sought to explain the mechanisms underlying KAE, and to use it as an index of perceptual learning and adaptation.
KAE is thought to involve a process of sensorimotor integration, which enables the sensory system to adapt to changing environmental conditions. This process is believed to involve a network of neural pathways that connect the sensory and motor systems, allowing for the coordination of movement and sensation. KAE is thought to be a form of short-term plasticity, in which the sensory system adapts to a changing environment. As such, KAE is believed to be a useful tool for studying the neural mechanisms underlying perceptual learning and adaptation.
Overall, KAE is a phenomenon in which the perception of a stimulus is altered by a prior experience. It is typically observed in the form of motion adaptation, and is thought to involve a process of sensorimotor integration. KAE is believed to be a form of short-term plasticity, and is used as a measure of perceptual learning and adaptation.
