This experiment tested the hypothesis that the sequence of ability and effort attributional feedback influences children's attributions, self-efficacy, and skillful performance. Children deficient in subtraction skills received training on subtraction operations and solved problems over four sessions. During the problem solving, some children…

Two experiments were conducted to test the hypotheses that the ability to draw inferences from a text about an unstated agent is based on the quality of information available to the reader, and that the quality of the information is itself based on the unique nature of cues embedded in the text and on the relevance of prior knowledge held by the…
