CONCEPT
The Feedback Timing Problem
The learning-science finding — uncomfortable and replicated — that immediate, specific feedback short-circuits development by eliminating the diagnostic gap in which mental representations are built.
There is a gap between an error and its correction that most practitioners experience as wasted time. The developer stares at a failing test. The musician replays a passage that refuses to sound right. In each case, there is a moment during which the practitioner knows something has gone wrong but does not yet know what. The natural impulse is to close the gap as quickly as possible. Ericsson's research, and the broader learning sciences his framework draws upon, suggest that this gap is not wasted time. It is the most developmentally productive phase of the entire practice cycle — the space in which the practitioner must engage her own cognitive resources to diagnose the problem, generate hypotheses, test them against what she knows, and construct a corrective response. The constructive process is the mechanism through which mental representations are assembled. The gap is where the learning lives. AI closes the gap with unprecedented immediacy and completeness, eliminating the diagnostic process in the name of efficiency.
