Final answer:
A communication barrier such as cultural norms, discomfort, shyness, or respect may contribute to Mr. Ono's lack of eye contact with his doctor during their interaction.
Step-by-step explanation:
The communication barrier most likely explaining Mr. Ono's lack of eye contact with his doctor could be attributed to cultural differences, discomfort, shyness, or a sign of respect. In some cultures, looking someone in the eyes is seen as confrontational or inappropriate, whereas in others it can be a sign of active listening and respect. Additionally, patients may avoid eye contact due to nervousness or fear about medical consultations, or as a non-verbal communication indicating that they are overwhelmed or unsure.
