We study a special case of the Stable Roommates problem in which preferences are derived from a psychological model common in social choice literature. When preferences are 'single-peaked' and 'narcissistic', there exists a unique stable matching, and it can be constructed in O(n) time. We also show how to recognize quickly, when a set of preferences is single-peaked.
