Balance,positivity, and agreement in the Jordan Paradigm: A defense of balance theory

It was argued that Heider's p?o?x triad can best be conceptualized according to a three- factor analysis of variance model in which the p?o, p?x, and o?x bands are all factors. From this perspective the balance effect is the triple interaction, the positivity effect a main effect for the p?o factor, and the agreement effect a p?x by o?x interaction. Although the existence of the latter two effects has previously been regarded as damaging to balance theory, it was shown that these effects could be interpreted from a balance perspective and that balance theory could be used to generate supportable propositions regarding these effects. Thus in agreement with a unit-relation interpretation it was shown, in accordance with balance theory, that positivity effects are obtained when the subject, or p, assumes future contact with o, that reverse positivity effects are obtained when the subject anticipates breaking off contact with o, and that no positivity effect is obtained when there is absolutely no contact, past or future. It was also demonstrated in an experiment involving the p?o?q triad that, in accordance with balance theory, positivity effects may be produced by the assumption or inference of same-sign reciprocation in sentiment. Evidence for two balance processes underlying agreement effects was also found. One of these processes was based on the assumption that the subject would have or reveal psycho-logical reasons for the disagreement and thus produce imbalance. Consistent with this interpretation it was found that the agreement effect was significantly larger when future contact with discussion of x was assumed than when future contact without discussion of x was assumed. The other, or unit-relation interpretation was supported by evidence indicating that the breaking off of contact resulted in a reversed agreement effect. In general, it was argued that balance theory did quite well in such phenomenological investigations when attention was not narrowly restricted to the three-sign pattern but considered other potential cognitive bands.     

Rational Selective Exploitation Among Americans and Chinese: General Similarity, With One Surprise

A cross-cultural experiment tested predictions regarding reward allocation decisions among subjects in the United States and Taiwan. The experiment included five independent variables—two between-subject factors (American vs. Chinese; instrumental vs. unspecified vs. social-emotional allocator orientation) and three within-subject factors (high vs. low employee competence, social skill, and mobility). In general, Americans and Chinese distributed rewards quite similarly: In both cultures, allocators distributed greater rewards to employees who were more competent and possessed greater social skill. In both cultures, instrumental allocator orientation induced stronger tendencies to base allocations on competence; social-emotional allocator orientation induced stronger tendencies to base allocations on social skill. In both cultures, subjects engaged in competence-based "rational selective exploitation"—among highly competent employees, those with greater professional mobility received larger portions of the reward pool than did counterparts with constrained mobility. In both cultures, subjects also evidenced an unexpected social-skill-based rational selective exploitation—among employees with good social skill those with greater professional mobility received larger portions of the reward pool than did counterparts with constrained mobility. However, there were a number of interactions with culture that ran contrary to our a priori predictions: We hypothesized that Americans would exhibit greater individualism by focusing on competence in allocating outcomes, and that Chinese would exhibit greater collectivism by focusing on social skill. Although Americans did attend to employee competence more than Chinese, Americans also attended to employee social skill more than Chinese. These findings are discussed in terms of an expanded conceptualization of the nature of individualism and collectivism.     

Group Learning Curves: The Effects of Turnover and Task Complexity on Group Performance1

This study examined the effects of turnover and task complexity on group performance. Two hundred and forty subjects arranged into three-person groups performed a production-type task for six experimental periods. The design was a 2 (Turnover vs. No Turnover) × 2 (Simple vs. Complex Task) × 2 (Male vs. Female) × 6 (Periods) factorial with repeated measures on the last factor. The analysis revealed that group performance improved markedly as groups gained experience with the task. Groups which did not experience turnover (closed groups) produced significantly more products than did groups which experienced turnover (open groups). The superior performance of closed over open groups was amplified over periods. Groups produced more of the simple than of the complex product, and this difference was also amplified over periods. The gap in the performance of closed versus open groups increased over periods, and the increase in the gap was greater for the simple than for the complex task. The lesser impact of turnover on the complex task is consistent with an innovation hypothesis, according to which increases in the production of complex tasks are due more to innovation than to repetition. Supportive analyses of innovation data are reported.     

Conformity as a function of the consistency of positive self-evaluation with being liked and being right

Insko, Sedlak, and Lipsitz (European Journal of Social Psychology, 1982, 13, 143–167) have presented evidence that agreement effects in p?o?x triads, or semicycles, are at least partially a function of the consistency of positive self-evaluation with being liked and the consistency of positive self-evaluation with being right. Consistent with the Insko et al. balance interpretation of agreement effects, results indicated that conformity in an Asch-type experiment is a joint function of the concern with being liked and the concern with being right. The judgment stimuli were sets of three colors, and the subjects' task was to indicate whether the middle color was more like the color on the left or the color on the right. In the main experiment, subjects conformed more with public than with private responding, and also when they were led to believe that the relationships among the colors were objectively determined rather than undetermined. The first of these two results (in conjunction with the lack of an interaction and the presence of a difference between the public condition and a private camera control condition) was taken as evidence for the concern with being liked. The second finding of a difference between the determined and undetermined conditions was taken as evidence both for the concern with being right and also as indicating that conformity can occur with objective stimuli. Although concepts similar to the concerns with being right and liked have been widely discussed, a review of the literature indicated that the previously presented evidence is not totally convincing.     

Beyond the group mind: a quantitative review of the interindividual-intergroup discontinuity effect

This quantitative review of 130 comparisons of interindividual and intergroup interactions in the context of mixed-motive situations reveals that intergroup interactions are generally more competitive than interindividual interactions. The authors identify 4 moderators of this interindividual-intergroup discontinuity effect, each based on the theoretical perspective that the discontinuity effect flows from greater fear and greed in intergroup relative to interindividual interactions. Results reveal that each moderator shares a unique association with the magnitude of the discontinuity effect. The discontinuity effect is larger when (a) participants interact with an opponent whose behavior is unconstrained by the experimenter or constrained by the experimenter to be cooperative rather than constrained by the experimenter to be reciprocal, (b) group members make a group decision rather than individual decisions, (c) unconstrained communication between participants is present rather than absent, and (d) conflict of interest is severe rather than mild.     

Interpersonal attraction and person perception: Two tests of three balance models

Two experiments tested the adequacy of three balance models (equal-weights tetrahedron model, unequal-weights tetrahedron model, Feather model) for the p?o?x triad. In the first experiment, involving a variation of Byrne's anonymous-stranger technique, a PDP-11 computer was used to provide feedback on five attitude issues for each of the cells of a design created by five levels of the p?x variable (?2, ?1, 0, +1, +2) and five levels of the o?x variable (?2, ?1, 0, +1, +2). The dependent variable was p?o, interpersonal attraction. In the second experiment there were five-level manipulations of both p?x and o?p with an o-x (person perception) dependent variable. The correlations between obtained results and the predicted values for each of the three models were quite high (.64, .65, .61, respectively, in the first experiment and .60, .59, and .58, respectively, in the second), but the Feather model was judged least adequate. The data in the first experiment were best described by the unequal-weights tetrahedron model, and the data in the second experiment were best described by the equal-weights tetrahedron model. It was argued that avoidance of mutual dislike was responsible for the relatively greater support for the unequal-weights than equal-weights tetrahedron model in the first experiment.     

Popular induction: When is consensus information informative?1

An experiment was conducted in which information regarding a target persons evaluation of a target object was presented either in written form or via video tape, and information regarding the evaluations of four other people was also presented either in written form or via video tape. The results indicated that the effect of consensus on both person and object attribution was significantly weaker when the target-person information was video taped (concrete) and the other-people information was written (abstract) than in the other three conditions created by the combination of the two informational variables. It is argued that, in contrast to earlier speculation in the literature, type of consensus and its mode of presentation represent conceptually orthogonal dimensions. Further research is urged to map out the boundary conditions of consensus information; it is demonstrated that current work has largely concentrated upon only a portion of this attributional domain due to the prevalent confounding of these two independent dimensions.     

A two-valued logic or two-valued balance resolution of the challenge of agreement and attraction effects in p-o-x triads,and a theoretical perspective on conformity and hedonism

Investigated the effect of three different variables on agreement effects in p-o-x triads. The subjects were 740 male and female undergraduates at the University of North Carolina. Experiment 1 found that assumed similarity modified the agreement effect—but only on cognitive rating scales (expectancy, consistency, stability). Experiment 2 found that assumed knowledgeability of o regarding × modified the agreement effect on both affective (pleasantness, harmony) and cognitive (expectancy, consistency, stability) scales. Experiment 3 found that a manipulation of o to p liking that was either consistent or inconsistent with p and o agreement modified the agreement effect primarily on the affective scales.
