B. F. Skinner, a strict behaviorist, believed that the environment is solely responsible for all human behavior. This includes the enduring and consistent patterns of behavior studied by personality theorists, which he viewed as entirely shaped by environmental consequences rather than by internal traits or biological influences.

B. F. Skinner, a prominent behaviorist, theorized that personality is not a fixed trait established in childhood but rather a collection of learned behaviors that develops continuously throughout life. He argued that what we perceive as personality is the result of 'response tendencies'—consistent patterns of behavior that are shaped and maintained by environmental reinforcements and consequences. According to Skinner, as an individual's environment and its system of rewards and punishments change, so too can their behavior and, consequently, their personality.

In B. F. Skinner's personality theory, response tendencies are the foundation of consistent behavior patterns. These are not inborn traits but learned inclinations to behave in certain ways. An individual develops these tendencies over time by learning to increase behaviors that lead to positive outcomes (reinforcement) and decrease behaviors that result in negative outcomes (punishment).

Response Tendencies (Skinner)

B. F. Skinner's and Sigmund Freud's theories on personality development are fundamentally opposed. Freud posited that personality is largely fixed in early childhood. In contrast, Skinner argued that personality is fluid and develops continuously throughout a person's life. Consequently, Skinner's model allows for significant personality changes over time as individuals encounter new situations and different patterns of reinforcement, a level of variability not anticipated by Freudian theory.

Skinner's vs. Freud's Views on Personality Development

An illustration of Skinner's theory involves Greta, a young woman who is a risk-taker, enjoying activities like fast driving and extreme sports. After she marries and has children, her environment's system of rewards and punishments changes. Risky behaviors are no longer reinforced, and she ceases to engage in them. As a result, her behavior pattern shifts, and she begins to describe herself as a cautious person, demonstrating how personality can evolve in response to new life circumstances.
