The effects of outcome expectancies on performance motivation are partly governed by self-beliefs of efficacy

Perceived self-efficacy and beliefs about the locus of outcome causality must be distinguished

Expected outcomes contribute to motivation independently of self-efficacy beliefs when outcomes are not completely controlled by quality of performance. This occurs when extraneous factors also affect outcomes, or outcomes are socially tied to a minimum level of performance so that some variations in quality of performance above and below the standard do not produce differential outcomes

For many activities, people cannot rely solely on themselves in evaluating their ability level because such judgments require inferences from probabilistic indicants of talent about which they may have limited knowledge. Self-appraisals are, therefore, partly based on the opinions of others who presumably possess evaluative competence

Behavior must also be adequately assessed under appropriate circumstances. Ill-defined global measures of perceived self-efficacy or defective assessments of performance will yield discordances. Disparities will also arise when efficacy is judged for performances in actual situations but performance is measured in simulated situations that are easier to deal with than the actualities

Most of the images of reality on which we base our actions are really based on vicarious experience.

Reasonably accurate appraisal of one's own capabilities is, therefore, of considerable value in successful functioning. Large misjudgments of personal efficacy in either direction have consequences. People who grossly overestimate their capabilities undertake activities that are clearly beyond their reach. As a result, they get themselves into considerable difficulties, undermine their credibility, and suffer needless failures. Some of the missteps, of course, can produce serious, irreparable harm
