Strengthened to forgive workplace transgressions: priming new money increases interpersonal forgiveness

We propose that a focus on new money increases forgiveness of others. Three studies provided consistent support for our hypothesis. Working adults recalled an interpersonal offense by a colleague and were subsequently induced to think of either new or used banknotes. Thinking of new (vs. used) banknotes led to weaker destructive tendencies toward the offender (Study 1), more pro‐relationship thinking (Study 2), and higher forgiveness (Study 3). This effect was mediated by feelings of vitality (Study 3), indicating a strength‐based mechanism. We discuss implications for research on money, forgiveness, self‐regulation, and organizational behavior.     

Working memory capacity and a notorious brain teaser: the case of the Monty Hall Dilemma

The Monty Hall Dilemma (MHD) is an intriguing example of the discrepancy between people's intuitions and normative reasoning. This study examines whether the notorious difficulty of the MHD is associated with limitations in working memory resources. Experiment 1 and 2 examined the link between MHD reasoning and working memory capacity. Experiment 3 tested the role of working memory experimentally by burdening the executive resources with a secondary task. Results showed that participants who solved the MHD correctly had a significantly higher working memory capacity than erroneous responders. Correct responding also decreased under secondary task load. Findings indicate that working memory capacity plays a key role in overcoming salient intuitions and selecting the correct switching response during MHD reasoning.     

Automatic-heuristic and executive-analytic processing during reasoning: Chronometric and dual-task considerations

Human reasoning has been shown to overly rely on intuitive, heuristic processing instead of a more demanding analytic inference process. Four experiments tested the central claim of current dual-process theories that analytic operations involve time-consuming executive processing whereas the heuristic system would operate automatically. Participants solved conjunction fallacy problems and indicative and deontic selection tasks. Experiment 1 established that making correct analytic inferences demanded more processing time than did making heuristic inferences. Experiment 2 showed that burdening the executive resources with an attention-demanding secondary task decreased correct, analytic responding and boosted the rate of conjunction fallacies and indicative matching card selections. Results were replicated in Experiments 3 and 4 with a different secondary-task procedure. Involvement of executive resources for the deontic selection task was less clear. Findings validate basic processing assumptions of the dual-process framework and complete the correlational research programme of K. E. Stanovich and R. F. West (2000).     

Motivated information processing, strategic choice, and the quality of negotiated agreement

The authors tested a motivated information-processing model of negotiation: To reach high joint outcomes, negotiators need a deep understanding of the task, which requires them to exchange information and to process new information systematically. All this depends on social motivation, epistemic motivation (EM), and their interaction. Indeed, when EM (manipulated by holding negotiators process accountability or not) was high rather than low and prosocial rather than proself, negotiators recall more cooperative than competitive tactics (Experiment 1), had more trust, and reached higher joint outcomes (Experiment 2). Experiment 3 showed that under high EM, negotiators who received cooperative, rather than competitive, tactics reached higher joint outcomes because they engaged in more problem solving. Under low EM, negotiators made more concessions and reached low joint outcomes. Implications for negotiation theory and for future work in this area are discussed.     

When sanctions fail to increase cooperation in social dilemmas: considering the presence of an alternative option to defect

Previous social dilemma research has shown that sanctioning defection may enhance cooperation. The authors argue that this finding may have resulted from restricting participants to two behaviors (cooperation and defection). In this article, the authors introduce the concept of a "social trilemma" (a social dilemma in which an alternative option to defect is present) and tested the effect of a sanction. The authors show that a sanction only increased cooperation and collective interests in the traditional social dilemma. In a social trilemma, the sanction failed because it caused some people to choose the alternative option to defect. Moreover, the results indicate that this was especially the case when people did not expect fellow group members to cooperate. In this case, the sanction even worked counterproductive because it decreased collective interests. It is concluded that allowing individuals to consider alternative options to defect can reveal the potential detrimental effects of sanctioning systems for the collective.     

Dual processing in reasoning: two systems but one reasoner

Human reasoning has been characterized as an interplay between an automatic belief-based system and a demanding logic-based reasoning system. The present study tested a fundamental claim about the nature of individual differences in reasoning and the processing demands of both systems. Participants varying in working memory capacity performed a reasoning task while their executive resources were burdened with a secondary task. Results were consistent with the dual-process claim: The executive burden hampered correct reasoning when the believability of a conclusion conflicted with its logical validity, but not when beliefs cued the correct response. However, although participants with high working memory spans performed better than those with lower spans in cases of a conflict, all reasoners showed similar effects of load. The findings support the idea that there are two reasoning systems with differential processing demands, but constitute evidence against qualitative individual differences in the human reasoning machinery.     

Oral kinesthetic deficit in adults who stutter: a target-accuracy study

The current study was based on the hypothesis that chronic developmental stuttering in adults involves a deficiency in oral kinesthesia. The authors used a target-accuracy task to compare oral kinesthesia in adults who stutter (n = 17) and in normal speakers (n = 17). During the task, participants were instructed to make accurate jaw-opening movements in visual and nonvisual feedback conditions. The authors further contrasted oral movement control in a normal response time condition with that in a reaction time condition. Overall, the adults who stutter consistently made significantly less accurate and more variable movements than the control participants in the nonvisual condition, but particularly in the reaction time condition. In general, the present findings suggest that chronic developmental stuttering involves an oral kinesthetic deficiency, although without direct measures of somatosensory function, one cannot exclude a motor deficit interpretation.
