The Limited Capacity Model of Motivated Mediated Message Processing (LC4MP) is a prominent model for investigating how human biological systems engage with and process messages. This chapter is a commentary on the LC4MP discussion by Lang and provides an engaging overview of the foundation and development of the LC4MP. Lang discusses her motivation for abandoning the LC4MP in favor of the Dynamic Human Centered Communication Systems Theory (DHCCST) and suggests that a recently published review and update of the LC4MP misrepresent the model’s assumptions and predictions. This chapter briefly responds to Lang’s arguments, highlighting the continued utility of the LC4MP for investigating human communication behavior.
