Abstract This study examined the interrelationships among certain personality traits, expressive behaviors, and naive judgments of personality. One hundred forty-nine subjects completed a variety of self-report personality measures and submitted handwriting samples. A subset of these subjects was videotaped in two separate situations. A number of expressive cues were coded from both the handwriting samples and the videotape segments. Groups of naive judges also rated handwriting samples and videotaped subjects on selected personality dimensions. The results indicated that specific personality traits, particularly extraversion, would be detected from naive observation of expressive behavior from both the videotaped expressive behavior and from handwriting samples. However, we were unable to uncover many of the specific behavioral cues that mediated the relationship between assessed personality and naive personality judgments. This research continues the investigation of the relationships between personality and expressive behavior—an area of research that is more than 50 years old, but one that has been much neglected.
