Social cognitive theory also differs from self-regulation in terms of self-reactions. According to Bandura and Cervone(1986), three types of self-influences mediate the relationship between goals and performance. These influences are self-satisfaction, self-efficacy and the regulation of internal standards. Self-regulation theory focuses primarily on the internal regulation of standards. Social cognitive theory, in contrast, stresses the importance of the self-reactive influences of satisfaction and self-efficacy. Self-efficacy is a key construct within social cognitive theory. Self-efficacy describes a person's self-assessment of the capabilities necessary to perform a specific task. Self-efficacy can influence aspirations, effort, persistence and thought patterns.
