on their observations of others' minor traits such as eye contact, fidgeting, open-handed gestures, stiff posture, smiling, etc. Behaviors such as frowning, fidgeting, and gazing down had poor ratings for traits describing the teacher's confidence, warmth and optimism while teachers with positive ratings for these traits smiled more, were more likely to walk around and touch their upper torsos. Ambady and Rosenthal ultimately found that those who rated the teachers after being subjected to thin slicing produced ratings that were very similar to those who rated the teachers after having substantial interactions with them. Additionally, the accuracy of these ratings was not significantly different among those who saw the 2-, 5- and 10-second clips. This demonstrates the impressive amount of information that is conveyed in thin slices of everyday behavior and the insight that it can provide about an individual's personality, no matter how briefly the behavior is observed. Domains People would expect that thin slices of themselves only reveal socially valued characteristics. Otherwise, they would be more willing to reveal minor imperfections about themselves before others make inferences based on their observations. Nonetheless, both desirable and undesirable characteristics are usually visible through the peephole of thin slices. Thin slices of individuals' behaviors could expose characteristics of their personality, internal states, sexuality, relationship, biases, etc. Even individuals' future behaviors could be predicted with reasonable accuracy through thin slicing. Interpersonal relationship First impression In the research paper published in 2007 by Dana R. Carney et al., it was discovered that increased exposure time, i.e. length of the slice, helped people to obtain more information, so that they could better judge social approach and positive affect. The same increased length of the slice was less related to judging threats and negative affect. The accuracy of the judgement based on a five-second long slice is significantly lower than the accuracy of judgments based on longer exposures. Also, slices extracted from the later stage of the interaction potentially allowed people to make more accurate judgments. Dana R. Carney et al. also drew the conclusion that women tended to make more accurate judgments using thin slicing than did men. Speed dating Marian L. Houser et al. built on Deyo & Deyo's earlier work and studied thin slicing in speed dating. They found out that a few moments of communication evaluation in Speed dating indeed helped the participants to predict outcomes and make speculated assessments of
