Jälkikokemus

Jälkikokemus refers to the residual sensory impression or feeling that lingers after a stimulus has ceased. This concept is particularly relevant in the fields of psychology, perception, and sensory science. It describes the continuation of a sensory experience, such as a taste, smell, sound, or visual image, even after the original source has been removed or is no longer present.

For example, the lingering taste of a strong spice after swallowing is a form of jälkikokemus. Similarly, a visual afterimage, where you continue to see a bright light or pattern after closing your eyes, is another manifestation. In auditory perception, the echo or reverberation of a sound can be considered a type of jälkikokemus. These experiences are typically brief and fade over time, but their duration and intensity can vary depending on the individual and the nature of the initial stimulus. The study of jälkikokemus helps researchers understand the mechanisms of sensory processing and memory in the brain.
