Reinforcement theory relates to personality development by emphasizing the role of external rewards and punishments in shaping behavior. This approach suggests that individual behaviors are learned through a system of consequences; positive reinforcement encourages the repetition of a behavior while negative reinforcement or punishment discourages it.

As individuals interact with their environment, the reinforcement they receive can significantly influence their personality traits over time. For example, someone rewarded for being sociable may develop a more extroverted personality as they continue to engage in social interactions to receive positive feedback. This dynamic illustrates how experiences and the subsequent reinforcement can play a crucial role in the ongoing development and modification of personality traits throughout a person's life.

Other options do not align with this concept. The notion of a fixed and unchangeable personality does not account for the influence of behavioral learning through reinforcement. Focusing solely on unconscious memories pertains more to psychodynamic theories rather than the behavioral focus of reinforcement. While genetics can have an impact, claiming that personality is solely inherited ignores the nuanced interactions between behavior and environmental factors emphasized by reinforcement theory.
