Final answer:
Interacting with a rationally behaving customer, Gwendolyn should engage in empathetic listening and present technical information, aligning with Rogers' principles of genuineness and empathy.
Step-by-step explanation:
When Gwendolyn is interacting with a customer who is exhibiting rational behavior patterns, a good response would be to engage in empathetic listening. This communication approach is aligned with the principles identified by Carl Rogers, who emphasized the importance of providing genuineness, empathy, and acceptance to clients to help them deal with their problems effectively. Rational customers typically appreciate when their thoughts and opinions are heard and understood, and they tend to respond well to logical explanations and factual information that can help them make informed decisions. Therefore, presenting clear, concise, and relevant technical information may also be effective, as it caters to the customer's desire for rational decision-making based on data and evidence, rather than emotional appeals or creative sales tactics.
