This one project has constituted around 80% of Dr. Bernieri's entire research effort over the last ten years. The inspiration for it was his awareness that every additional measure taken on a research participant increases the number of empirically testable hypotheses exponentially. See Dr. Bernieri's presentation slideshow from the SPSP 2016 Nonverbal Preconference for a more detailed description of this project.
The BISP involved about 50 hours of observation or assessment of each participant over a ten week period. With this research paradigm we have tracked the development of trait perception accuracy within participants from zero-acquaintance (between strangers) to when they become well-acquainted with each other and have developed the rate at which accuracy increases across different traits and attributes such as intelligence. New measures of encoding ability (emotional communication), deception, and deception detection have been developed from this project as well.
The true intent of the BISP, however, is to establish the viability and utility of this relatively large social psychology research paradigm in order to secure funding for an even larger replication that will include measures of physical and mental health.
