Implicit theories, attributions, and coping: A meaning system approach.
Abstract
This research sought to integrate C. S. Dweck and E. L. Leggett's (1988) model with attribution theory. Three studies tested the hypothesis that theories of intelligence—the belief that intelligence is malleable (incremental theory) versus fixed (entity theory)—would predict (and create) effort versus ability attributions, which would then mediate mastery-oriented coping. Study 1 revealed that, when given negative feedback, incremental theorists were more likely than entity theorists to attribute to effort. Studies 2 and 3 showed that incremental theorists were more likely than entity theorists to take remedial action if performance was unsatisfactory. Study 3, in which an entity or incremental theory was induced, showed that incremental theorists' remedial action was mediated by their effort attributions. These results suggest that implicit theories create the meaning framework in which attributions occur and are important for understanding motivation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
