His theory defines human behavior as a three-way, dynamic, and reciprocal interaction of personal factors, behavior, and the environment. According to this theory, the behavior of an individual is determined by three factors with more emphasis on the cognitive processes that mediate learning. Response consequences of a behavior are used as expectations of behavioral outcomes. It is the ability to form these expectations that give humans the capacity to predict the outcomes of their behavior, before the behavior is performed. In addition, the social cognitive theory posits that most behavior is learned vicariously. Bandura's social cognitive theory suggests that humans can learn through observation without imitating the observed behavior. Bandura is also credited with the theoretical construct of self-efficacy and is responsible for the research in the influential 1961 Bobo doll experiment.
