Flow is the state in which a person is totally engaged in a sense of focus that allows them to achieve themselves at full performance and enjoyment in the process of the activity. The term flow was coined by Mihaly Csikszentmihalyi, who held the position of head of the department of psychology at the University of Chicago, in 1975. The flow state is a state of intense concentration and focus where action and awareness merge. In the flow state, there is a feeling of personal agency or control over a situation or action. A temporal experience distortion occurs when one's subjective perception of time is affected. Autotelic experience refers to the perception of an action as inherently gratifying.
