Mastery versus performance goals
Also known as: Learning goals vs performance goals, Task vs ego goals
Aiming to get better at something behaves very differently from aiming to prove you're good at it.
What it means
This is the central distinction within achievement goal theory between mastery goals, oriented toward developing competence and understanding using a self-referential standard, and performance goals, oriented toward demonstrating competence relative to others. Mastery goals are typically associated with deep processing, intrinsic interest, help-seeking, and adaptive responses to failure, because errors are information rather than verdicts. Performance goals tie self-worth to outcomes and social comparison, which can spur effort in the short run but invites anxiety, surface learning, and self-handicapping when difficulty mounts. The crucial refinement is the approach-avoidance split: performance-approach goals (outperforming others) sometimes predict high achievement, whereas performance-avoidance goals (not looking incompetent) are reliably maladaptive. It matters because how a teacher or manager frames a task can install one orientation or the other.
Examples
A pianist practicing to deepen her musicality keeps experimenting after mistakes; one practicing to win a competition freezes when a passage exposes a weakness.
A developer told the code review is for learning asks about the parts she found confusing; one told it feeds her ranking submits only the file she is sure about.
A learner using a language app to hold a real conversation keeps talking through mistakes; one chasing the leaderboard streak replays easy lessons that guarantee a perfect score.
