Albert Bandura (1925–2021) was a Canadian-born American psychologist whose work reshaped how learning, motivation, and human action are understood. Across six decades at Stanford University he moved psychology away from the view that behaviour is stamped in by reward and punishment toward an account in which people learn by watching others, regulate themselves by thought, and act on beliefs about what they can do. His social cognitive theory and the construct of Self-Efficacy are among the most cited ideas in twentieth-century psychology, and both reach deep into education.
Bandura was born on 4 December 1925 in Mundare, a small town in Alberta, Canada, the youngest of six children of Eastern European immigrant farmers. He took his bachelor's degree at the University of British Columbia (1949), then a master's (1951) and a doctorate in clinical psychology (1952) at the University of Iowa, where the rigour of the experimental tradition marked his approach. He joined the faculty of Stanford University in 1953 and remained there for the rest of his career, named David Starr Jordan Professor of Social Science in Psychology in 1974 and becoming professor emeritus in 2010. That same year, 1974, he was elected president of the American Psychological Association. His standing was recognised late with the National Medal of Science, presented by President Barack Obama in 2016. He died on 26 July 2021 in Stanford, California, at the age of 95.
Bandura's books trace the arc from behaviour observed to belief examined. His early studies of aggression yielded Adolescent Aggression (1959, with Richard Walters) and Aggression: A Social Learning Analysis (1973). The most influential statement of his early framework was Social Learning Theory (1977), which argued that much of what people learn comes not from acting and being reinforced but from watching others and forming expectations. Over the following decade he broadened the theory into a full account of human functioning in Social Foundations of Thought and Action: A Social Cognitive Theory (1986), the work in which "social learning" became "social cognitive" to mark the central place of thought. His culminating treatment of the efficacy construct appeared in Self-Efficacy: The Exercise of Control (1997), drawing together two decades of research that began with his 1977 Psychological Review article.
Four interlocking ideas carry Bandura's mark. The first is observational learning, established by the Bobo doll experiments he ran with collaborators in 1961: nursery-school children who watched an adult attack an inflatable clown doll later imitated the aggression, while children who saw no such model did not. The studies showed that behaviour can be acquired simply by watching, without the watcher ever being rewarded, a direct challenge to strict behaviourism. The second is reciprocal determinism, his model of three forces, the person (thoughts and beliefs), behaviour, and environment, each shaping and being shaped by the others, so that a learner is neither the passive product of surroundings nor a free agent above them. The third is self-efficacy, the belief in one's capability to carry out a specific task, which became the most generative of his ideas for education, clinical psychology, and health. The fourth, drawing the others together, is human agency: his insistence that people are self-organising, proactive, and self-reflective rather than reactive to forces around them.
For teaching, the influence is concrete. Self-efficacy reframed motivation around competence beliefs and gave educators specific levers, success experiences and credible feedback, to raise them. Observational learning underwrites modelling and demonstration as core instructional moves. His later work on self-regulation fed directly into research on how learners plan, monitor, and adjust their own studying. The reach also draws criticism. Reviewers note that the breadth of social cognitive theory can make it hard to falsify, that the central efficacy–outcome distinction has been contested as conceptually entangled, and that the agentic emphasis can underweight social and structural constraints on what learners are actually free to do. Bandura engaged these critiques directly across his career, and the framework remains a working foundation of educational and motivational psychology.
