Research Interests:
Dr. Lassiter's main line of research centers on the problem of how people come to organize and comprehend the information contained in another person's ongoing stream of behavior. This is a question that is of fundamental importance to several areas of psychology, including social, cognitive, and clinical as well as to other disciplines such as sociology, communication, and political science whose focus is also concerned with issues related to the nature of social action and interaction. The overall goal of Lassiter's work, which has been funded by the National Science Foundation, is to further illuminate the nature of the behavior perception process and at the same time establish its prominent role in a variety of psychological phenomena.
Dr. Lassiter's interest in behavior perception has recently branched out into the study of decision-making in simulated juries. This research has also been funded with a grant from the National Science Foundation. Within the criminal justice system, there is a growing trend toward using videotape technology to record and present confession evidence. Videotaping confessions has the ostensible advantage of helping trial fact finders determine more objectively whether a confession was voluntary or coerced. However, the social-psychological literature on perceptual salience suggests that certain aspects of this process could inadvertently bias or prejudice judgments of voluntariness and guilt.
Consistent with this literature, Dr. Lassiter's research shows that, relative to other confession-presentation formats (e.g., audiotapes and transcripts), videotapes that are recorded with the focus on the confessor tend to produce judgments of greater voluntariness and guilt. In light of both a recent U. S. Supreme Court ruling stating that the improper use of involuntary confessions may in certain instances be considered "harmless error," and the fact that actual criminal interrogations are usually videotaped with the focus on the confessor, these findings have important legal implications. The real-world impact of Dr. Lassiter's research is demonstrated by the fact that it has already influenced New Zealand's national policy on the videotaping of police interrogations.
