Impression management in the forced compliance situation: Two studies using the bogus pipeline

Two studies were performed to assess the interpersonal concerns of subjects in the forced compliance paradigm. The first study counterposed dissonance and impression management theory predictions in a 2 × 2 design by varying the public versus private nature of the counterattitudinal behavior and by assessing attitudes with the usual pencil-and-paper method or with a bogus pipeline technique designed to create strong pressures toward sincere reporting. Attitude change occurred only in the Public/Pencil-and-Paper condition and thus supported an interpersonal or impression management interpretation. The second study examined the effect of measuring the critical attitude a second time in the mode not experienced in the first assessment. This three-group design (Pencil-and-Paper/Bogus Pipeline, Bogus Pipeline/Pencil-and-Paper, Control) demonstrated that attitude change occurred only in the Pencil-and-Paper/Bogus Pipeline condition and was maintained on the second assessment when measured by the bogus pipeline. A common-factor analysis of the secondary measures in the second study demonstrated that the Pencil-and-Paper/Bogus Pipeline subjects reported a great deal of negative arousal such as embarrassment and guilt, while the subjects in the Bogus Pipeline/Pencil-and-Paper condition reported feeling manipulated and constrained. The findings of both studies were interpreted as consistent with impression management theory.     

Unclogging the bogus pipeline: A critical reanalysis of the Cherry,Byrne, and Mitchell study

The assignment of subjects to conditions on the basis of social desirability scores could not have been done in the manner described by Cherry, Byrne, and Mitchell (Journal of Research in Personality, 1976, 10, 69–75). Even if subject assignment procedures were not challenged the data do not support the authors' conclusions. Additional statistical analyses were carried out to test the hypotheses of the original study. It is concluded that either the demand cue manipulation was not successful or else paper-and-pencil and bogus pipeline measurement procedures are equally reliable measurement devices for the attitude similarity effect.     

Verbal accounts and attributions of social motives

The effects of verbal accounts offered by a threatener on targets' subsequent attributions of the threatener's social motives was studied. Following a standardized interaction in a Prisoner's Dilemma game the subjects' opponent offered one of three accounts for using threats: cooperative intent, establishment of transrelational equity, or ignorance. In a fourth condition the confederate offered no account for his actions. Attributions were assessed by having subjects rate each of four responses representative of the social motives of cooperation, competition, apathy, and deceit in five different situations. It was found that the type of account had specific attributional effects. A cooperative account led to a correspondent inference of a cooperative disposition, a transrelational equity account was apparently perceived as illegitimate and led to an attribution of a deceitful motive, and an excuse of ignorance was linked with apathy.     

Comprehension,selective imitation,and the CIP hypothesis

The role of comprehension training in the selective imitation of indirect-direct object sentences was assessed for six preschool children. A modeling condition resulted in normal usage of indirect-direct object sentences for five of six subjects, but reversed usage was not obtained when modeling was reversed. Subsequent receptive comprehension training on normal and reversed forms of indirect-direct object sentences resulted in generalization to the productive mode. These results were related to an hypothesis about language acquisition in which selective imitation is a function of comprehension.     

Distraction and social comparison as mediators of social facilitation effects

Sanders and Baron (Journal of Personality and Social Psychology, 1975, 32, 956–963) suggested that increases in drive produced by the presence of others (social facilitation) are due to the tendency for others to distract task performers as they worked on a task. This Distraction-Conflict theory proposes that socially mediated drive induction will occur whenever there is some reason to shift attention from the task to the social stimuli. In the case of humans, one such reason may be the opportunity to obtain social comparison information from an audience or coactors. The present research demonstrated that social facilitation effects (improved simple task performance and impaired complex task performance produced by the presence of others) occurred only when subjects were motivated to obtain comparison information (Experiment I) and when comparison information was available (Experiment II). The availability of comparison information also led to increased accuracy in estimating the coactor's performance. This indicated that in conditions manifesting social facilitation, subjects were spending some time monitoring the coactor's work, which is an inherently distracting activity. Several supplementary measures of distraction were generally consistent in indicating greater distraction under conditions manifesting social facilitation. The present results offer no support for the explanations of social facilitation suggested by Zajonc and by Cottrell.     

An ethological analysis of open-field behavior in rats and mice

In our view open-field testing entails both a predatory encounter, which occurs as a consequence of handling and placement of subjects into the testing apparatus, and sudden social separation from conspecifics. We hypothesize, therefore, that open-field behavior represents a compromise between responses aimed at minimizing detectability as a predator evasion tactic, and those which are motivated by attempts to reinstate contact with companions. Six experiments were conducted using rats and mice to test various implications of this model. Pretest shock and the presence of a human observer each retarded the appearance of social reinstatement behaviors and enhanced responses which minimize detectability in both species. Likewise, because of diminished reinstatement tendencies animals tested in pairs froze longer than those tested individually. The applicability of this model to other aspects of open-field behavior in rodents was examined, and the contrast between this view and the general emotionality hypothesis was briefly discussed.     

Probabilistic contingency theories of animal conditioning: A critical analysis

Seven contingency theories of classical and instrumental conditioning were defined in relation to the contingency matrix and to six separate probabilities which can be derived from this matrix. These theories were compared on the basis of formal similarities and differences, and were judged against three separate empirical variables which have been discussed in the contingency literature: the duration of the intertrial interval, partial reinforcement, and negative contingencies between the two events of conditioning. All previous theories had some difficulty predicting the effects of one or more of these variables upon animal conditioning. Also, some formulas make the unusual prediction that there will be less conditioning when there is more than one conditioning trial. The paper concluded with an extensive discussion of the problems that are created by conditioning events with temporal extension; events which are then categorized by a contingency matrix which has no temporal character. Some possible solutions to the problems were discussed.     

Reinforcement rate and force proportional reinforcement

The research examines the consequences of making two reinforcement contingencies simultaneously available for the same bar-pressing response. Specifically, two experiments are described which concern the effects of reinforcement rate upon force proportional reinforcement (FPR). In Experiment 1, reinforcement rate was constrained by combining differential reinforcement of low rate with a force-proportional reinforcement contingency. The group of rats exposed to this regimen eventually showed a significant increase in response force compared to control groups. Experimental vs control response rates were not significantly different. In Experiment 2, reinforcement rate was affected through the expedient of relating the probability of obtaining a single pellet to the response force. The group for which the probability-force relationship was discontinuous came to exert higher forces than either a group for which the relationship was fairly continuous or an ordinary variable ratio control group. Response rate was significantly higher for the control group.     

An analysis of the word-superiority effect

It is easier to decide which of two letters was presented tachistoscopically if the critical letter was in a word rather than in a scrambled word. We showed that this word-superiority effect holds just as strongly for pronounceable nonwords as for words, even when the critical letters are constant over all trials. This finding rules out word meaning and familiarity as variables accounting for the effect. In addition, it was found that the superiority of pronounceable stimuli holds for two-letter stimuli as well as four, and it is therefore concluded that the effect is not due to a memory limitation. An explanation of the effect in terms of the use of additional acoustic information is ruled out by showing that the effect was not diminished when the two possible words sounded exactly alike. An experiment using correctly and incorrectly spelled chemical formulas suggested that spelling regularities, regardless of pronounceability per se, account for the superiority effect. Finally, when decisions about two critical letters must be made on each trial, the correlation between being correct on one and on the other is higher for pronounceable stimuli under some conditions.
