Is symmetry identity?

Wigner found unreasonable the "effectiveness of mathematics in the natural sciences". But if the mathematics we use to describe nature is simply a carefully coded expression of our experience then its effectiveness is quite reasonable. Its effectiveness is built into its design. We consider group theory, the logic of symmetry. We examine the premise that symmetry is identity; that group theory encodes our experience of identification. To decide whether group theory describes the world in such an elemental way we catalogue the detailed correspondence between elements of the physical world and elements of the formalism. Providing an unequivocal match between concept and mathematical statement completes the case. It makes effectiveness appear reasonable. The case that symmetry is identity is a strong one but it is not complete. The further validation required suggests that unexpected entities might be describable by the irreducible representations of group theory.     

Reduction of interindividual-intergroup discontinuity: the role of leader accountability and proneness to guilt

Two experiments contrasted interactions between group leaders with interactions between individuals in a mixed-motive setting. Consistent with the idea that being accountable to the in-group implies normative pressure to benefit the in-group, Experiment 1 found that accountable leaders were more competitive than individuals. Consistent with the idea that being unaccountable to the in-group implies normative pressure to be cooperative and that high guilt proneness provides motivation to be moral, Experiment 2 found that when guilt proneness was high, unaccountable leaders were less competitive than accountable leaders and did not differ significantly from individuals. In other words, the robust interindividual-intergroup discontinuity effect was eliminated when groups had unaccountable leaders who were high in guilt proneness.     

The effects of alignments: examining group faultlines, organizational cultures, and performance

By integrating literature on group faultlines, organizational cultures, and value congruence, this research presents a framework that explains how cultural alignment across organizational levels may influence the relationship between faultlines and performance. The hypotheses were tested using representatively sampled multisource qualitative and quantitative data on 138 teams from a Fortune 500 company. The present findings demonstrate that although informational faultlines were detrimental for group performance, the negative relationship between faultlines and performance was reversed when cultures with a strong emphasis on results were aligned, was lessened when cultures with a weak emphasis on results were aligned, and remained negative when cultures were misaligned with respect to their results orientation. These findings show the importance of recognizing alignments not only within groups (group faultlines) but also outside groups (cultural alignments between the group and departments) when considering their implications for group performance.     

The Relation of the Galvanic Skin Reflex Recovery Curve to Reactivity,Resistance Level,and Perspiration

The effect of stimulus compounding in classical conditioning was investigated by conditioning one group of rats to a compound CS consisting of a buzzer and light and then conditioning separate groups of rats to the individual elements of the compound CS. On hurdle-jump test trials, the group of Ss conditioned to the compound CS performed better than Ss conditioned to the elements of the compound. Strength of conditioning to each of the elements of the compound CS was about equal. There was some evidence of a summation effect resulting from conditioning to the compound CS. Strength of conditioning to the compound CS was somewhat greater than the sum of the response strengths conditioned to the elements of the compound CS.     

Role of emotions and behavioural responses in mediating the impact of face loss on relationship deterioration: Are Chinese more face‐sensitive than Americans?

Face loss, defined as the deterioration in one's social image, has been regarded as a consequence of interpersonal conflict and a provocation for counter-attack. The present research was aimed at assessing whether the role of face loss in leading to relationship deterioration has more impact for Chinese than for Americans. We hypothesized that the linkage from face loss to relationship deterioration is mediated by two social-emotional complexes (anger and shame) and two behavioural reactions (retaliation and avoidance) arising from interpersonal harm. Structural equation modelling confirmed this mediation model, and indicated that in both cultures, the linkage between face loss and relationship disintegration was mediated by shame and avoidance, but not by anger and retaliation. Consistent with widely held hypotheses, face loss was found to be more influential in directly provoking a target's anger and relationship deterioration, and more influential in inhibiting a target's retaliating responses, for Hong Kong Chinese than for Americans.     

The survival of a cooperative tradition in the intergroup discontinuity context

Interindividual-intergroup discontinuity is the tendency, in mixed-motive situations, for groups to interact more competitively, or less cooperatively, than individuals, even though mutual competition yields worse results that mutual cooperation. The present laboratory experiment attempted to assess whether the discontinuity effect could be reduced by the establishment of an intergroup cooperative tradition. Cooperation between intact pairs of groups was induced by placing in each group confederates who successfully convinced their fellow group members of the long-term advantage of trust and cooperation. On subsequent blocks of trails, the confederate was replaced by an actual subject, and then each of the original subjects was replaced so as to simulate generational turnover. By the time all initial members were replaced, their level of cooperation had eroded to the level of groups never experiencing mutual cooperation. The results are discussed in the context of other means of reducing discontinuity.

The Relation of Cognitive and Memorial Processes to Persuasion in a Simulated Jury Trial

Four experiments investigated the dependence of persuasion on cognitive factors. All experiments employed a court case for which 795 subjects acted as jury members, reading summaries of both the prosecution and defense's testimony. The amount of objective information on both sides of the case was varied. Persuasion was a position function of the number of prosecution arguments and the number of defense arguments. This finding was extended by obtaining measures of the subjects'cognitive reactions to the case as well as their opinions and by following both of these measures over time. Both analysis of variance and multiple regression techniques showed that subjects could have derived their opinions from their cognitions about the case. This relationship also held up over time. These results suggest the general form of an information-processing theory of persuasion. One prediction of this theory is for an asymptotic function relating objective information to persuasion. This prediction received empirical support.     

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.
