From my experience with IRNs I don't believe this is a reinforced behaviour, it's just something IRNs do when they don't like something in their environment, his trust and security issues are challenged when a stranger enters his environment. Personally I think the only way you are going to avoid the screaming is to move him when you know a visitor is coming and put him back to his regular environment when there are no visitors.
Or that.
