As a general rule, moderate levels of arousal facilitate deployment of skills, whereas high arousal disrupts it. This is especially true of complex activities requiring intricate organization of behavior
Albert BanduraPeople'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
Albert BanduraSelf-appraisals of efficacy are reasonably accurate, but they diverge from action because people do not know fully what they will have to do, lack information for regulating their effort, or are hindered by external factors from doing what they can
