Koherenssiehdot

Koherenssiehdot, also known as coherence dots, are a phenomenon observed in the visual perception of humans and some animals. They are small, dark spots that appear to move coherently with the observer's eye movements, despite being stationary in the environment. This effect is often described as a form of visual illusion where the dots seem to follow the observer's gaze.

The phenomenon was first described by the psychologist James J. Gibson in the 1950s. He proposed that coherence dots are a result of the brain's attempt to stabilize the visual field during eye movements. When the eyes move, the image on the retina shifts, and the brain uses coherence dots to maintain a stable perception of the environment.

Koherenssiehdot have been studied extensively in the field of visual perception and have been used to investigate various aspects of human vision, including eye movement control, visual attention, and the integration of sensory information. They are also of interest in the study of visual illusions and the mechanisms underlying visual stability.

The exact mechanisms by which coherence dots are generated and perceived are still not fully understood. However, research suggests that they may be related to the brain's processing of visual motion and the use of eye movements to explore the environment. Further studies are needed to elucidate the underlying neural mechanisms and the functional significance of coherence dots in visual perception.
