slices were accurate, and approximately 70% of the judgments based on 10 second silent video slices were accurate. Such perception and judgment would be more accurate if the materials provided were of dynamic nonverbal nature (e.g.: silent videos containing much gestural information) rather than of static information nature (e.g.: still photographs). Also in her studies, gay men and lesbians were generally more accurate than heterosexuals in making judgments. Clinical Cognitive ability An individual's mood has been known to distort cognitive abilities. Emotions cloud rational quick thoughts. The three most influential studies were conducted in 2002 by Nalini Ambady and Heather M. Gray. In the first study, induced sadness led to reduced accuracy in judgments of teacher effectiveness from brief samples of nonverbal behavior. In the second study, sad participants showed reduced accuracy in judging relationship type from thin-slices as well as diminished judgmental efficiency. The third study showed the possibility that sadness impairs accuracy by promoting a more deliberative information-processing style. All of these studies have the basic principle that emotions do in fact affect judgement as seen through effects on thin-slicing. They disprove conclusions from some previous studies that sadness would lead to more cautious processing strategy or would not have a strong effect in social perception, and argue that short-term induced sadness would hinder individual's social interpretation skills. Personality disorder Jacqueline N.W. Friedman et al. (2007) examined people's ability to detect personality disorder using a thin-slicing approach. They found that people were capable of detecting pathological personality traits in 30 seconds of videotaped behavior. By looking at the "thin slices" of videos, research participants were able to accurately identify targets with personality pathology from the video. Also, when participants were exposed to an increased number of personality traits, i.e.: increasing spectrum instead of "thickness" of the slices, they performed better at identifying targets' negative traits. This correlation between "thin slices" with richer content and participants' better performance in detecting personality disorder is found to be stronger than correlations found in other studies using thin slice methodology. Deception detection Albrechsten, Meissner and Susa (2009) of the University of Texas at El Paso conducted two separate studies of processing style (intuitive vs. deliberative processing) in a deception detection task. In the first experiment, a thin-slicing manipulation was used to show that intuitive processing can lead to more accurate judgments of deception when compared with traditional forms of processing, i.e.: forms
