Misbeliefs in one's inefficacy may retard development of the very subskills upon which more complex performances depend

Learning would be exceedingly laborious, not to mention hazardous, if people had to rely solely on the effects of their own actions to inform them what to do. Fortunately, most human behavior is learned observationally through modeling: from observing others one forms an idea of how new behaviors are performed, and on later occasions this coded information serves as a guide for action.

People’s beliefs about their abilities have a profound effect on those abilities.

People who are burdened by acute misgivings about their coping capabilities suffer much distress and expend much effort in defensive action... they cannot get themselves to do things they find subjectively threatening even though they are objectively safe. They may even shun easily manageable activities because they see them as leading to more threatening events over which they will be unable to exercise adequate control.

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

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

The presence of many interacting influences, including the attainments of others, create further leeway in how one's performances and outcomes are cognitively appraised
