Final answer:
James's increased engagement with the clinician using the MI approach is indicated by increased eye contact and conversation.
Step-by-step explanation:
In the first case scenario where the clinician uses the MI approach with James, his increased engagement is indicated by 1) increased eye contact and 3) increased conversation. This implies that both verbal and non-verbal communication signals are showing greater participation and interest during the intervention. Direct eye contact is a key indicator that someone is engaged and alert in a conversation, while increased conversation reveals that James is more actively participating in the session with the clinician. Looking away or avoiding eye contact may indicate lack of interest or disengagement.
