Investigated was the criterion validity of confidence-testing as applied to a multiple-choice test in introductory psychology. Examinees made confidence judgements in addition to choosing the correct alternative. The test was scored conventionally with a penalty for guessing and again using confidence-weightings.

High test anxiety was associated with low confidence and poor achievement.
