Patients’ Characteristics Affecting Physician-Patient Nonverbal Communication

Previous research has reported that nonverbal elements of physician-patient communication influence medical outcomes such as patients’ understanding, compliance, and saris/action with health care delivery. This investigation examined the impact of various patients’ characteristics (age, sex, education, anxiety, and relational history with the physician) on patterns of nonverbal communication exhibited in 41 physician-patient interactions at a family practice clinic. Several findings were noteworthy. First, although they were relatively consistent in their nonverbal responses to different patients, physicians generally reciprocated patient's adjustments in response latency, pauses during speaking turns, body orientation, and interruptions and compensated patient's modifications in turn duration and gestural rates. Second, physicians nonverbally interacted with patients over 30 years of age in a less domineering and more responsive fashion (e.g., comparable turn durations, more vocal back-channels, and more nonverbal behavior reciprocity) than they did when conversing with patients under 30. Third, physicians appeared responsive to patients experiencing various degrees of anxiety. Specifically, relative to their interactions with less worried patients, physicians used less task touch with anxious patients and to a greater degree compensated the worried patients nonverbal responses. Finally, the patients sex, education, and visit (i.e., first versus repeat) had little impact on the structure of physician-patient nonverbal exchanges.     

THE TRUTH-DECEPTION ATTRIBUTION: EFFECTS OF FAMILIARITY ON THE ABILITY OF OBSERVERS TO DETECT DECEPTION

This study investigated the relationship between an observer's familiarity with the normal, truthful communicative behavior of an individual, and the observer's ability to detect deception on the part of that individual. Specifically, an attempt was made to provide an experimental test of the degree of linearity between familiarity and judgmental accuracy in detecting deception. After exposure to varying amounts of a communicator's normal, truthful behavior (baseline segment), observers made judgments of a communicator's veracity following observation of truthful or lying behavior (test segment). The results indicate a significant deviation from linearity in the relationship between familiarity and judgmental accuracy, and that the relationship is better described by an inverted parabolic curve (quadratic function). The possibility of information overload, the possibility of communicator-specific characteristics which provide clues to deception, and the possibility of observer fatigue were proposed as possible explanations of these results.
