Just ran across this rather thoughtful piece. It would seem to have implications for interpersonal relationships in survival conditions, almost by definition times when people are stressed - emotionally and physically.

On a much less epic scale, i have come to realize that many of SAR experiences have put me in somewhat similar situations, although for shorter periods. Certainly there are other situations which breed similar responses...

Note that the author does not claim that all situations will resolve equally well.
