Final answer:
The question refers to the behavioral theory of leadership, which holds that leadership skills and behaviors can be learned over time through experience, education, and interaction with others.
Step-by-step explanation:
When one suggests that a leader can acquire communication skills and leadership behavior over time, one is following the behavioral theory. This theory posits that leadership is not a static trait or solely dependent on one's personality or inherent characteristics; rather, it can be learned and improved upon through experience, observation, and education. Leaders can develop their style by responding to their environments and through interactions with followers, who each have individual needs for growth and development. This concept echoes the ideas of theorists such as Bandura, who highlighted the importance of reciprocal determinism and observational learning in the development of an individual's behavior.
