The behavioural approach to personality emphasizes the significance of observable behaviour, asserting that personality can be understood as the responses of individuals to their environment rather than relying on introspective techniques or unobservable constructs. Key figures in this approach include John B. Watson and B.F. Skinner, who focused on learning processes such as classical conditioning, operant conditioning, and observational learning. This approach suggests that personality development is influenced by reinforcement and conditioning, allowing individuals to adapt their behaviours in accordance with situational demands. In addition, concepts such as self-regulation highlight the importance of individuals managing their behaviours based on external requirements and internal standards. The relevance of this approach extends to various fields, including education and clinical psychology, providing tools for behaviour modification and assessment.
