Facial and vocal cues of deception and honesty

Facial expressions and vocal cues (filtered speech) of honest and deceptive messages were examined in posed and spontaneous situations. The question of interest was the degree to which nonverbal cues transmit information about deception. Results indicated that (a) for both the facial and vocal channels, posing (as compared to spontaneous behavior) produced a higher level of communication accuracy; (b) facial expressions of deceptive (as compared to honest) messages were rated as less pleasant, while vocal expressions of deception were rated as less honest, less assertive, and less dominant, particularly in the posed condition; (c) the sender's ability to convey honesty was negatively correlated with his/her ability to convey deception, suggesting the existence of a demeanor bias—individual senders tend to appear and sound consistently honest (or dishonest) regardless of whether they deliver an honest or a deceptive message; (d) in the posing condition, the sender's abilities to convey honesty/deception via facial and vocal cues were positively and significantly correlated, whereas in the spontaneous condition they were not; and (e) senders whose full (unfiltered) speech indicated more involvement with their responses were judged as more honest from both their vocal (filtered speech) and facial cues, in both the honest and deceptive conditions.     

Selective perception of events

Two hundred and twelve subjects were given one of two interpretive sets prior to viewing an event. Following observation, the first interpretation was discredited, and subjects were asked to interpret the event they had seen under the contrasting set. Some subjects were only provided with the alternate interpretation, while others were also given an opportunity to view the event a second time. Both the perceptual segmentation and the subjects' impressions of the participants in the event were assessed. Results disclosed that (1) the two sets produced both differing perceptual organization and differing impressions of the participants; (2) reversing the sets produced a reversal of the impressions of the participants only when accompanied by a second viewing; and (3) the reversal of the impressions was accompanied by a shift in the perceptual organization of the event. It was concluded that observers may differ in their initial perception of an event as the result of differences in prior expectations, and that the resulting biased sample of information they acquire may limit their retrospective reinterpretation of the event.     

The dispositional shift in attribution over time

Two experiments examined the effect of time on causal attributions. In Experiment I, subjects who described themselves into a tape recorder assumed more personal responsibility for their behavior after 3 weeks' time than others who explained their behavior immediately after its occurrence. In Experiment II, actor-subjects took part in a getting acquainted conversation and explained their behavior more dispositionally and less situationally after 3 weeks' time than they had initially, while observer-subjects experienced no change over time. Results were interpreted in terms of an altered self-perspective in memory and the diminished salience of situational details over time.     

Alleys in visual space

Geometry of frameless visual space is dealt with. First, parallel and equidistant alleys, horopters in the horizontal plane of eyes' level are discussed within the framework of the Luneburg's model that the frameless visual space is a Riemannian space of constant curvature. That basic postulate and the specific mapping functions assumed by Luneburg between the euclidean map of visual space and the physical space are kept separate, and efforts are directed to make the model applicable to more natural conditions of our visual space. A possibility is pointed out to remove the constraint “frameless” in the sense that perceptual geometrical properties are primarily determined by the convergence of optic axes. So far, only alleys in the horizontal plane extending from us toward infinity have been studied, but more often we perceive parallel lines, horizontal or vertical, in front of us like shelves of a bookcase. Hence, equations are derived for horopter plane appearing fronto-parallel in the three-dimensional visual space and alleys running horizontally or vertically on the horopter plane. It is shown that parallel and equidistant alleys are not the same in the horopter plane as in the horizontal plane, if the visual space is not euclidean. A method to evaluate the discrepancy between the two alleys without using any mapping functions is stated with some numerical examples.     

Effects of household sex composition on the salience of one's gender in the spontaneous self-concept

It was hypothesized that being a boy or a girl becomes more salient in a child's self-concept to the extent the other sex numerically predominates in the child's household. This prediction was based upon an information-processing, distinctiveness postulate that a person contemplating a complex stimulus (such as the self) selectively notices and encodes its more distinctive, information-rich aspects. The spontaneous self-concept elicited by nondirective “Tell us about yourself” interviews of 560 school children were scored for spontaneous mention of one's gender. As predicted, boys spontaneously mentioned their maleness more often when they came from households where females were in the majority; girls mentioned their femaleness more often when from households with male majorities; boys mentioned their maleness more often when from father-absent than from father-present homes. Incidental findings are that gender is more salient in the negation self-concept (“Tell us what you are not”) than in the affirmation self-concept (“Tell us about yourself”) especially for girls and that gender becomes increasingly salient as the child grows older.     

The role of attribution in the experience of crowding

The theory that the subjective experience of crowding results from an attribution of arousal process was examined. Specifically, it was predicted that subjects who were aroused by having their personal space violated would experience less crowding if they were led to believe that some other environmental factor was responsible for the arousal. Groups of subjects were placed in a room in which their personal space was either violated or not violated. Some subjects were told that either an arousing or a relaxing subliminal noise would be played into the room. (Actually there was no noise.) Other subjects were told nothing about subliminal noise. The subjects worked on a number of tasks and were then asked to report how crowded they felt. The noise manipulation had no effect on subjects' performance nor on feelings of crowdedness when their personal space was not being violated. However, when there was a violation of personal space, subjects who felt the noise would arouse them reported being less crowded and performed better than subjects in the relaxing noise or no explanation conditions. It was suggested that subjects attributed their arousal to the “arousing noise” and hence felt less crowded.     

Indirect social influence: Change in judgmental process or anticipatory conformity?

In three experiments, subjects imposed sentence in a criminal case before and after reading the harsh sentence imposed by the trial judge. They then read and imposed sentence in another case. In one experimental condition the subjects anticipated learning the judge's sentence in Case 2; in the other condition they were told not to anticipate learning the judge's sentence. Control subjects made their judgments without ever seeing the judge's sentence. Direct influence was the change in sentences within cases; indirect influence was the difference between initial sentences in Cases 1 and 2. Though direct influence was minimal and not significant, indirect influence was substantial, and was greater in the anticipation than no-anticipation than control conditions, indicating that both modification of the judgmental process and anticipatory conformity were operating. Indirect influence may then reflect a change of either type, depending on a number of methodological and other factors.     

Student counseling groups in senior high school settings: An evaluation of outcome

This paper reviewed the studies which evaluated counseling groups in senior high school settings. A methodological evaluation was conducted within four areas: subjects, counselors, treatment, and outcome criteria. The studies were reviewed according to the type of outcome measure: achievement, attitude and personality, behavioral, and vocational. Three levels of voluntariness (voluntary, semivoluntary, and nonvoluntary) were examined in relation to outcome. Subjects who were free to volunteer for the group experience achieved greater gains than subjects who were coerced into participation. Overall, behavioral and directive groups achieved greater success than nondirective or client-centered groups. The time spent on topics relating to treatment goals appeared to be an important factor for success. Future researchers should assess the effects of treatment on each participant instead of relying upon group mean changes.     

The effects of conditioning and novelty on the rat's analgesic and pyretic responses to morphine

Six experiments with rat subjects investigated the role of conditioning in morphine tolerance. Concurrent assessments of body temperature and pain sensitivity were conducted. Experience with morphine produced tolerance to its analgesic effects but enhancement of its hyperthermic effects. Environmental novelty enhanced analgesia but not body temperature (Experiments 1 and 4). Under conditions in which a discriminated hyperthermic CR provided clear evidence that morphine-environment learning had developed, discriminated analgesic tolerance was not obtained (Experiments 2 and 3). Similarly, whereas placebo administrations extinguished the hyperthermic CR (Experiments 4 and 6), analgesic tolerance remained unaffected (Experiments 4, 5, and 6). These experiments suggest that the pyretic and analgesic systems are differentially sensitive to conditioning and the effects of novelty.
