Physical Markers as Predictors of Behavior

    This study examined the connection between external, physical traits (markers) and behavior.  Using the Big Five personality dimensions derived from standard personality tests and markers identified in literature on the topic, a researcher found statistically significant correlations (p > .01) within some dimensions.  For example, adults, drawn from a pool of 123 subjects and scoring high on extroversion, possessed a complex of specific markers such as long index fingers, strong thumbs, firm stylus pressure, strong, high-ascending crossing of lower case ts and darker eye coloration.  The findings are not surprising, based on genetic and zoological studies that have found consistent polygenic interactions between physical traits and animal behavior.  These noninvasive methods could aid in basic patient behavioral assessment.
