Peter's expression when jan saw him at lunch was difficult to decode. one part of his face registered one emotion and another part of his face registered a different emotion. therefore, peter was demonstrating an ambivalent display dissembling a decptive display an affect blend

Therefore, Peter was demonstrating an "affect blend."


Affect blend alludes to an outward appearance in which one part of the face is enrolling one feeling and another piece of the face is enlisting an alternate feeling. In short we can say that it is facial expressions uncovering at least two feelings at the same time. 

This one hard but um i have no idea i’m sorry
