Self-belief does not necessarily ensure success, but self-disbelief assuredly spawns failure.

Self-efficacy is the belief in one's capabilities to organize and execute the sources of action required to manage prospective situations.

People's conceptions about themselves and the nature of things are developed and verified through four different processes: direct experience of the effects produced by their actions, vicarious experience of the effects produced by somebody else's actions, judgments voiced by others, and derivation of further knowledge from what they already know by using rules of inference

The difficulty in judging what type of behavior works well arises not only because a given course of action does not always produce the outcomes. Similar outcomes can occur for reasons other than the person's actions, which further complicates inferential judgment. Effects that arise independently of one's actions distort the influence of similar effects produced by the actions, but only on some occasions. Given a strong cognitive set to perceive regularities, even chance joint occurrences of events can be easily misjudged as genuine relationships of low contingent probability

This has increased with the tremendous technological advances in communications. We have a vast new world of images brought into our sitting rooms electronically. Most of the images of reality on which we base our actions are really based on vicarious experience. This has increased with the tremendous technological advances in communications. We have a vast new world of images brought into our sitting-rooms electronically.

Comparative appraisals of efficacy require not only evaluation of one;s own performances but also knowledge of how others do, cognizance of nonability determinants of their performances, and some understanding that it is others, like oneself, who provide the most informative social criterion for comparison

Measures of self-precept must be tailored to the domain of psychological functioning being explored.
