Document Summary

Impressions of strangers are formed very quickly -> snap judgements: ex. Participants shown faces and have to rate how trustworthy, competent, likeable, aggressive, and attractive they were. Iv: some were given lots of time to examine the face, others only milliseconds. Results: time didn"t make a signi cant difference on the ratings: correlation between judgements made at leisure and those made under time pressure. Much of what we conclude about a person based on their face is determined instantaneously. Adults with baby-faces judged to be weak, naive, and submissive. Adults with small eyes, forehead, and angular chin judged as strong, competent, dominant. People can make reasonably accurate judgements from thin slices of behaviour: ex. experimenters showed participants shorts clips of inmates and asked which ones they thought were psychopaths. Their judgements correlated signi cantly with the trained assessments made on the basis of extensive interviews: ex. students shown short clips of different professors and asked to rate them.
