This aligns with the faculty member's statement about people being unaware of the unconscious drives behind their actions. Choice A, F. Skinner, is incorrect because Skinner focused on observable behavior and reinforcement.

Choice C, 'Atypical development,' pertains to deviations from typical developmental patterns and is not directly related to the continuous changes across the lifespan. Choice D, 'Maturation,' specifically refers to the biological process of growth and development, which is different from the broader concept of developmental changes occurring across the lifespan.
