๐๏ธ
afterimage
[ หษหftษrหษชmษชdส ]
visual perception
An afterimage is a visual illusion that occurs when you continue to see an image even after the stimulus has been removed. This phenomenon is caused by the overstimulation of photoreceptors in the eye, leaving a residual impression on the retina. Afterimages often appear in complementary colors to the original stimulus.
Synonyms
ghost image, retinal image

Etymology
The term 'afterimage' comes from the combination of 'after' and 'image', referring to the phenomenon that occurs after an initial visual stimulus has been removed. The concept has been studied since the 19th century, as scientists began to understand more about human vision and perception. Early experiments by researchers such as Hermann von Helmholtz explored the mechanics of how images are perceived and how they linger in the mind. The understanding of afterimages played a role in the development of color theory and the study of optical illusions. The phenomenon is not only of interest in psychology but also has applications in art, photography, and even neuroscience, as it provides insights into the functioning of the human eye and brain's processing of visual information.
