Do First Impressions Last

Is three seconds the definitive time for a 1st Impression?

 Hang onto your hat. Recent studies have shown that all it takes is one tenth of a second to form a first impression of a stranger after seeing their face. Research has shown that although longer exposures might increase the confidence in that first impression, it does not significantly alter that first impression. It seems that you never have a second chance to make a good first impression professionally and rarely have a second chance to make a good first impression on a personal level. When getting a 1^st impression of another individual, take context into consideration. Pick up on multiple body-language cues and be sensitive to cultural differences that may impact expression of body language.
