The Perceptual Contrast Explanation of Sequential Request Strategy Effectiveness

Although previous studies of the foot-in-the-door and the door-in-the-face techniques of interpersonal influence have established the effectiveness of these sequential request strategies, communication researchers have not discovered an adequate conceptual framework for explaining their compliance-enhancing properties. The present study tests the perceptual contrast explanation for sequential request efficacy. Compared with nonsequenced critical requests (i.e., controls), substantially higher compliance with various types of requests was obtained through the use of the foot-in-the-door and the door-in-the-face techniques, but measures of underlying cognitions failed to reveal significant anchoring effects as would be predicted by a perceptual contrast model. Limitations are discussed and suggestions for future research are offered.     

Experiments in Group Decision Making Communication Process and Outcome in Face-to-Face Versus Computerized Conferences

A 2 × 2 factorial design was used to explore the process and outcome of small group problem-solving discussions for two modes of communication (face-to-face and computerized conferencing) and two types of tasks (a qualitative human relations task and a scientific ranking test with a criterion solution). Interaction process was coded using Bales Interaction Process Analysis. There were two to three times as many communication units in the face to-face groups consisting of five members each as in the computerized conferencing mode of communication during the same elapsed time. Group decisions were equally good in the two modes, but the groups were less likely to reach agreement in the computerized conferencing mode. There were proportionately more of the types of task-oriented communication associated with decision quality in the computerized conferences.     

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.
