Encoding and decoding of nonverbal behavior through facial expressions

Ten males and ten females served as both senders and receivers of nonverbal expressions in an experiment designed to examine various kinds of sending-receiving relationships. While the overall sending-receiving relationship for five types of expressions combined was positive and nearly statistically significant (.10 > p > .05), the category-specific sending-receiving relationships were near zero in magnitude or slightly negative. Sending-receiving relationships that were category specific and involved same-sex communication attempts only were found to be more negative with some being statistically significant. Females were found to be significantly better receivers but not significantly better senders than males. The results were discussed in terms of recent theoretical notions concerning sending and receiving processes.     

Exposure effects in person perception: Familiarity,similarity, and attraction

Two experiments explored the relationship between familiarity, similarity, and attraction. In the first experiment, subjects viewed photographs of faces at various exposure frequencies and then rated them for likeableness and similarity. Familiar people were regarded by the subjects as both more likeable and more similar to themselves. The effects of familiarity on perceived similarity were primarily mediated by changes in attraction, although some evidence of a direct link between familiarity and perceived similarity was also found. In the second experiment, subjects viewed the same stimuli at a single exposure frequency, and received bogus information regarding the similarity of the people shown therein. Subsequent ratings of likeableness and perceived familiarity revealed that people who seemed similar to the subjects were regarded as both more likeable and more familiar. The effects of similarity on perceived familiarity were almost entirely mediated by changes in attraction. Some of the theoretical implications of these findings are discussed.     

Immediate and delayed effects of victim suffering on the attacker's aggression

On the first day of a two-day experiment, male undergraduates were either angered or not, and they were given either high, low, or no metered pain feedback after each shock they supposedly delivered to their previous evaluator for his errors on a learning task. After the learning task the subjects made a number of ratings, including how much they had enjoyed this first session. On the second day, all subjects were simply required to administer shocks to a different person for his mistakes on the same learning task. The angered subjects were more punitive on both days toward both learners than the nonangered men. On the first day the angered men also increased the intensity of the shocks they delivered over trial blocks. Most interestingly, the angered men showed more enjoyment of the first session of the experiment as their victim's pain increased, and this enjoyment rating was related to the angered subjects' level of aggression on the second day of the experiment when they punished an “innocent” victim. The results were interpreted as consistent with the hypothesized reinforcement process which essentially states that signs and/or knowledge of the victim's suffering can reinforce impulsive or angry aggressive behavior.     

Developmental differences in reactions to children labeled mentally retarded

In an attempt to examine age-related differences in response to the mental retardation label, 48 4th and 5th graders and 48 11th and 12th graders were told of a child of their own age and sex who was either labeled mentally retarded or unlabeled and who performed either competently or incompetently in giving a report. Incompetent target children were viewed more negatively than competent ones at both grade levels. The mental retardation label had less generalized impacts, leading girls but not boys (a) to cite lack of ability as the reason for a retarded child's failure, and (b) to hold low expectations that retarded targets would hold jobs, marry, or have children. A developmental shift in responses to the label was evident only on a trait perception measure; younger children stigmatized retarded targets, while older children granted special dispensation of a failing retarded child by viewing him or her more positively than a similarly incompetent but unlabeled child. Since only adolescent boys showed special dispensation, even though girls were more generally attentive to the label, both sex and age differences warrant further examination.     

Functional similarity and interpersonal attraction

A pair of related experiments examined the relationship of functional similarity (i.e., the degree of similarity between two interactants in assessing mutually known others on personal construct dimensions) to interpersonal attraction. In Experiment I, 10 previously unacquainted college students of both sexes participated in 10 hours of dyadic disclosure exercises over a 5-week period. As predicted, members of high functional similarity dyads evidenced greater attraction to one another than did members of low functional similarity dyads. Experiment II investigated the relationship of functional similarity to level of acquaintance (i.e., friends, nominals) and type of assessment (i.e., physical, interactional, psychological) in a 2 × 3 factorial design. As hypothesized, “friendship” pairs of male undergraduates displayed greater functional similarity than did “nominal” pairs from the same population, particularly at the deeper level of “psychological” assessment. Results are discussed in relation to classical conditioning (D. Byrne, In L. Berkowitz (Ed.), Advances in experimental social psychology, Vol. 4. New York. Academic Press, 1969), affect-reinforcement (G. L. Clore, In S. W. Duck (Ed.), Theory and practice in interpersonal attraction. New York/London: Academic Press, 1977) and information processing ( I. Ajzen, In S. Duck (Ed.), Theory and practice in interpersonal attraction, New York/London: Academic Press, 1977) models of interpersonal attraction, and are interpreted as supporting and extending (S. Duck's Theory and practice in interpersonal attraction, New York/London: Academic Press, 1977) filtering theory of friendship formation.     

Interpersonal congruency,attitude similarity,and interpersonal attraction

To examine relationships among interpersonal congruency, attitude similarity, and interpersonal attraction, the present study required pairs of subject to rate their attraction to each other in response to two proportions of similar attitudes orthogonally varied with two treatments of interpersonal congruency. Findings showed that attitude similarity determined attraction when congruency was uncontrolled, but that similarity and attraction were unrelated within the two congruency treatments. Additional correlational analyses suggest that different judgments of the accuracy of other's perceptions of oneself accompany previous findings on attitude similarity and attraction, and it is proposed that interpersonal attraction may be understood in terms of stabilizing processes postulated by the theory of interpersonal congruency.     

Belief similarity and attitude similarity as determinants of interpersonal attraction

It was predicted that attraction would be a function of both attitude similarity and belief similarity, but that attitude similarity would have the greater influence. In Expt I, 60 subjects were presented with strangers that were either similar or dissimilar on attitude and on belief. Attraction was a positive function of both attitude similarity (p < .05) and belief similarity (p < .01). Experiment II replicated and extended Expt I with the addition of a 50% similar group for both attitude and belief. Attraction was a positive linear function of both attitude similarity (p < .001) and belief similarity (p < .02); departure from linearity was not significant. Attitude similarity also had greater effects on other aspects of interpersonal evaluation than belief similarity. The results were discussed in terms of the locus of reinforcement of attitude similarity and of belief similarity.     

The effects of sensation seeking and misattribution of arousal on attraction toward similar or dissimilar strangers

While previous research has indicated that certain situational variables can mediate the typical positive relationship between attitudinal similarity and attraction, investigations focusing on the impact of individual difference variables on this relationship have typically yielded unimpressive results. The present experiment was conducted to test the prediction that individual differences in sensation seeking do moderate this relationship. The major results showed that, as predicted, high sensation seekers were more attracted than low sensation seekers to dissimilar others, whereas low sensation seekers were more attracted than high sensation seekers to people with similar attitudes. The data also indicated that a misattribution of arousal manipulation serves to increase attraction under certain conditions. Specifically, misattribution of aversive arousal increased low sensation seekers' attraction to a dissimilar stranger and increased high sensation seekers' attraction to a similar stranger.     

Some attitudinal and cognitive consequences of thought

A “reinterpretation of inconsistent cognitions” explanation of the previous finding that thought about an object tends to polarize attitudes toward that object was tested. Under the assumption that ambiguity facilitates reinterpretation, ambiguity of inconsistent information and opportunity for thought were manipulated. Consistent with expectations, (a) thought resulted in attitude polarization and this effect was increased with ambiguity (p < .01) and (b) evaluation (interpretation) of the inconsistent information varied as a function of thought (p < .05) and ambiguity (p < .01).     

II. The comparability of the WISC-R and WAIS among 16-year-old EMR children

Thirty 16-year-old EMR children were administered the WAIS and WISC-R in counterbalance order to determine the comparability of the two assessment instruments. The WAIS was found to yield significantly higher Verbal, Performance, and Full Scale IQ scores. The comparisons of corresponding subtests indicate that all WAIS subtests were significantly higher than the WISC-R except Picture Completion. Correlations between corresponding WAIS and WISC-R IQ scales and subtests, however, were significant. The results suggest differences between the two instruments among children of subnormal intelligence, thus presenting the possibility that a child may be differentially classified based on the selection of the intelligence test.     

The effects of verbal and behavioral noncompliance on third party instigation of aggression

Females, assigned to one of four conditions defined in terms of a confederate's behavior, suggested which shock intensity the confederate ought to set for an opponent during a reaction time competition, should the opponent lose the trial (had slower reaction time). Confederates either verbally complied or disagreed with suggestions to set high shock, while either actually setting the intensity suggested or setting a lower intensity. Over trials, the opponent became increasingly provocative. Results revealed the main effects and interaction of confederate's verbal and actual behaviors, as well as provocativeness of the opponent, significantly influenced the level of shock subjects suggested. Subjects with verbally and behaviorally compliant confederates suggested more intense shock than subjects who encountered any noncompliance.     

The effects of observation on emotional arousal and affiliation

This study assessed the influence of anticipated experimenter surveillance during the performance of a painful or potentially embarrassing act on affiliative preferences before engaging in that act. As predicted, there was an overall preference for isolation when the act to be performed was embarrassing, and this tendency increased with anticipated surveillance. There was an overall preference for affiliation under fear arousal, and this preference also increased with anticipated surveillance. Contrary to previous research, whether or not the potential affiliate was a subject in the experiment (i.e., in a similar or dissimilar emotional state) did not affect these tendencies. Possible ways of accounting for these findings are discussed.     

Relation of the verbal transformation and the phonemic restoration effects

This study examined the relationship between illusory changes of repeated words (“verbal transformations” or VTs) and illusory presence of phonemes replaced by noise (“phonemic restorations” or PhRs). Separate groups of 20 subjects were each presented with one of four taped variations of the repeated stimulus word “magistrate”: stimulus intact (MAGISTRATE); speech sound “s” removed and replaced with a silent gap (MAGI TRATE); speech sound “s” removed and replaced with a louder extraneous sound (MAGI¹TRATE); syllable “gis” removed and replaced with a louder extraneous sound (MA⁷¹TRATE). The stimuli MAGI¹TRATE and MA⁷¹TRATE evoked PhRs, and with these stimuli, the phonetic changes corresponding to VTs were concentrated at the perceptually restored portions of the word. It is suggested that both PhRs and VTs are related directly to perceptual processes employed normally for the correction of errors and resolution of ambiguities in speech. Other effects of PhRs upon VTs are described and implications of these findings for mechanisms underlying speech perception are discussed.     

Effects of perceived similarity on vicarious emotional conditioning

The present experiment tested the hypothesis that perceived similarity between observers and models enhances vicarious emotional conditioning. Subjects were led to believe that they were either similar to the model in beliefs and attitudes, different from him or were given no information about him. They then underwent a vicarious classical conditioning procedure by witnessing the model express pain reactions in conjunction with a neutral stimulus. Observers developed emotional reactions to the neutral stimulus alone after seeing it paired with modeled pain expressions. Preceived similarity, however, had no significant effect on either the level of vicarious conditioning or the rate of extinction. Subjects who had no information concerning the model displayed stronger autonomic responses to the model's pain expressions, and more frequent and intense autonomic responses to the conditioned stimulus during tests for acquisition and extinction. In correlational analyses, subjects in the latter condition also yielded a significant positive relationship between self-reported arousal and vicarious emotional conditioning. The obtained findings were interpreted in terms of the emotion arousing properties of unfamiliarity.     

The meaning of observed violence: Real vs. fictional violence and consequent effects on aggression and emotional arousal

Sixty male subjects were either attacked or treated neutrally by a confederate, after which each saw a videotape of two men fighting. Subjects were informed that fight was either real or fictitious or were given no explanation of it. Subjects who had previously been attacked and had observed the fight under a set to perceive it as real were subsequently more punitive in their treatment of the confederate than subjects in all other conditions. The combination of prior attack and observation of real violence also sustained blood pressure (BP) at near the level produced by the attack, whereas BP of attacked subjects in the other conditions declined during the time the fight was observed. Palmar sweat measures revealed that observation of real violence was more arousing than observation of fictitious fighting. The results are discussed in terms of the effects that the reality of observed violence has on emotional arousal.     

Self-awareness and physical aggression

A theory of self-awareness was applied to aggression. In Experiment I, men were given an opportunity to aggress against women in the presence of a mirror, an audience, or neither. The mirror significantly inhibited aggression, but the audience did not. In Experiment II, an audience inhibited aggression, but only when there was frequent eye contact between the aggressor and the audience. These results were consistent with the predictions derived from the theory.     

The effects of perceived similarity upon the use of reward and punishment

Subjects were led to perceive a trainee as either similar or dissimilar to themselves. During subsequent influence trials, subjects attempted to assess the causes of the trainee's performance and to employ rewards, punishments, or manipulations of the trainee's environment to optimize her performance. It was predicted that subjects would perceive the performance of dissimilar trainees as caused more by the dispositional factor of motivation than the performance of similar trainees, and that dissimilar trainees would thus be rewarded more upon success as well as punished more upon failure. The hypotheses were supported, and a model of reward-punishment behavior and attribution is discussed.     

Attibution of attitudes to speakers and listeners under assigned-behavior conditions: Does behavior engulf the field?

A conceptual replication of the assigned-behavior conditions of previous research in attitude attribution was conducted. Participants made attitude attributions about themselves and also about others who had either given, listened to, or not been exposed to either a proattitudinal or counterattitudinal essay. The position adopted in the essay significantly affected the attitudes attributed to those assigned to deliver the essay. Essay position had an equally strong effect upon attitudes attributed to those who merely listened to the essay, however. Thus, the fact that the actor had delivered a particular assigned essay apparently did not in itself convey information to the observers about the actor's attitudes. Experimental results suggested that essay direction affects attitudes attitudes attributed to others in an assigned-behavior setting because observers use their own attitudes to infer the attitudes of others. Since observers' own attitudes change after exposure to different essays, they attribute different attitudes to others.     

Disinhibition of aggression through diffusion of responsibility and dehumanization of victims

The present study tested derivations from social learning theory on the disinhibition of aggression through processes that weaken self-deterring consequences to injurious conduct. Subjects were provided with opportunities to behave punitively under diffused or personalized responsibility toward groups that were characterized in either humanized, neutral, or dehumanized terms. Both dehumanization and lessened personal responsibility enhanced aggressiveness, with dehumanization serving as the more potent disinhibitor. Escalation of aggression under conditions of dehumanization was especially marked when punitiveness was dysfunctional in effecting desired changes. The uniformly low level of aggression directed toward humanized groups, regardless of variations in responsibility and instrumentality of the conduct, attested to the power of humanization to counteract punitiveness. Results of supplementary measures are consistent with the postulated relationship between self-disinhibiting processes and punitiveness. Dehumanization fostered self-absolving justifications that were in turn associated with increased punitiveness. Findings on the internal concomitants of behavior performed under different levels of responsibility suggest that reducing personal responsibility heightens aggressiveness more through social than personal sources of disinhibition.
