After the study, how do you think the prisoners and guards felt when they saw each other in the same civilian clothes again and saw their prison reconverted to a basement laboratory hallway.

I believe the prisoners and guards would have felt awkward on seeing each other in same civilian clothes.

It would be hard for them to handle while walking through the hallway.

Explanation:

At the conclusion of the study, I believe the students would have probably felt awkward on interacting with one another in classes and in public. Definitely the guards may feel ashamed of how they treated the prisoners. On the other hand the prisoners would feel cowed in the presence of those who treated them so poorly. Dr. Zimbardo says that the effect of study won't last long on the lives of the participants.

Walking through the hallway again will make prisoners to handle it hard as they lived in prison there for some time. Especially when they were in psychology classes, because it was the room where they were isolated from the outside world and verbally abused. I'm sure it will be difficult for the participants to adjust back into their normal behaviors and routines.
