Tall tales make fast friends: Exaggerating when retelling previous experiences fosters relational closeness
Holly Cole & Denise Beike
Journal of Social and Personal Relationships, forthcoming
Abstract:
This research explores the possibility that exaggerating in order to entertain the listener while sharing previous experiences can increase interpersonal closeness in new relationships. It is hypothesized that adding exaggerations about previous experiences will increase the quality of the story, which will lead to increased interpersonal closeness, and that even listeners who are provided with the actual facts will show this effect. Three studies with 592 total participants investigated the impact of exaggerating when sharing a story about a previous experience on feelings of closeness to the storyteller. In Study 1, participants read scenarios of a person telling a story about a previous experience. Results indicate a preference for exaggerated stories and a concomitant feeling of closeness to the storyteller. In Study 2, participants retold the events of a video to another participant who was a stranger. Participants instructed to give an entertaining recalling used more exaggerations, and listeners felt closer to them. In Study 3, participants watched a video of a confederate retelling events accurately or with clear exaggerations. Participants reported feeling closer to the confederate when exaggerations were included, even when they knew the facts the storyteller was retelling. Discussion centers on reasons why being entertaining was more beneficial in creating relationship closeness than being honest.
Beautiful mess effect: Self–other differences in evaluation of showing vulnerability
Anna Bruk, Sabine Scholl & Herbert Bless
Journal of Personality and Social Psychology, August 2018, Pages 192-205
Abstract:
Confessing romantic feelings, asking for help, or taking responsibility for a mistake constitute just a few examples of situations that require showing one’s vulnerability. Out of fear, many individuals decide against it. To explore whether these fears are reflected in the evaluation of others, we investigate self–other differences in evaluation of showing vulnerability. Drawing on construal level theory, we hypothesize that the mental representations of individuals who find themselves in a vulnerable situation are rather concrete, shifting the focus on the negative aspects of making oneself vulnerable and resulting in a relatively negative evaluation of showing vulnerability. By contrast, when depicting others in a vulnerable situation, individuals are expected to represent it more abstractly, focus more on the positive aspects of showing vulnerability, and, therefore, evaluate it more positively. A total of seven studies demonstrate the predicted self–other differences in the evaluation of showing vulnerability in various situations, such as confessing love, revealing imperfections of one’s body, or asking for help, including evidence on the generalizability of the effect in a real-life situation. Moreover, we report empirical evidence on the crucial role of level of construal in the emergence of the observed self-other differences.
Taking one for the team: Physiological trajectories of painful intergroup retaliation
Elizabeth Niedbala et al.
Physiology & Behavior, October 2018, Pages 277-284
Abstract:
Retaliating against a threatening outgroup offers group members specific rewards, such as restored group esteem, a reduction in anger, and a sense of gratification. Because retaliation is rewarding, group members may appraise an attack on the outgroup to be beneficial, even if it feels physically painful. We hypothesized that group members would be more willing to endure pain to retaliate against a threatening outgroup, and that appraising the painful retaliation as rewarding would down-regulate their physiological stress response to pain. Participants were manipulated to feel threatened by a rival group and then completed the cold-pressor. During the cold-pressor, participants either retaliated against the outgroup or not. Results showed that retaliation inhibited physiological responses to pain, alleviated intergroup anger, and felt less aversive. We propose that these responses are caused by a cognitive reappraisal of pain, where painful retaliation is expected to be rewarding instead of threatening.
Thin Slices of Athletes’ Nonverbal Behavior Give Away Game Location: Testing the Territoriality Hypothesis of the Home Game Advantage
Philip Furley, Geoffrey Schweizer & Daniel Memmert
Evolutionary Psychology, May 2018
Abstract:
The present research investigated whether perceivers could detect who is playing at home or away in soccer matches based on thin slices of professional (Experiment 1) and amateur (Experiment 3) athletes’ nonverbal behavior prior to the match and whether perceivers rated athletes playing at home relatively higher on behavioral dimensions (Experiments 2 and 3) linked to territoriality. In Experiment 1 (N = 80), participants watched short videos depicting soccer players prior to a UEFA Champions League match and rated whether athletes were more likely to be playing at home or away. In Experiment 2 (two groups N = 102 and N = 101), perceivers rated these videos in terms of assertiveness, dominance, and aggression. In Experiment 3, we replicated the procedure of Experiments 1 and 2 with different stimulus material from amateur soccer (N = 112). Participants could significantly differentiate between home playing and away playing athletes (Experiment 1: d = 0.44 and Experiment 3: d = 1.07). Experiments 2 and 3 showed that perceivers rated professional and amateur soccer players higher on assertiveness (d = 0.34–0.63), dominance (d = 0.20–0.55), and aggression (d = 0.16–0.49) when playing at home compared to playing away. Findings are supportive of evolutionary accounts of nonverbal behavior, ecological approaches to person perception, and the thin slices of behavior hypothesis by demonstrating that humans change their nonverbal behavior depending on game location. We discuss the relevance of the present findings for the home advantage in sports.
Learning to Trust: From Relational Exchange to Generalized Trust in China
Victor Nee, Håkan Holm & Sonja Opper
Organization Science, forthcoming
Abstract:
Where does generalized trust — that is, the inclination to place trust in strangers — come from? Our claim is that in economic action, sources of generalized trust may not differ much from the sources of personalized trust. Contrary to a common assumption of a sharp distinction between personalized and generalized trust, we assert a likely spillover effect from relational exchange to a person’s expectations in interacting with an anonymous other. Our research integrates behavioral measures elicited by a novel incentivized trust game with survey data using a random sample of 540 entrepreneurs of private industrial firms in the Yangzi delta region of China. We show that entrepreneurs with more experience in relational exchange display greater trust in strangers. Likewise, we find robust evidence of a positive association between beliefs in the effectiveness of community business norms and generalized trust.
Pupil mimicry promotes trust through the theory-of-mind network
Eliska Prochazkova et al.
Proceedings of the National Academy of Sciences, forthcoming
Abstract:
The human eye can provide powerful insights into the emotions and intentions of others; however, how pupillary changes influence observers’ behavior remains largely unknown. The present fMRI–pupillometry study revealed that when the pupils of interacting partners synchronously dilate, trust is promoted, which suggests that pupil mimicry affiliates people. Here we provide evidence that pupil mimicry modulates trust decisions through the activation of the theory-of-mind network (precuneus, temporo-parietal junction, superior temporal sulcus, and medial prefrontal cortex). This network was recruited during pupil-dilation mimicry compared with interactions without mimicry or compared with pupil-constriction mimicry. Furthermore, the level of theory-of-mind engagement was proportional to individual’s susceptibility to pupil-dilation mimicry. These data reveal a fundamental mechanism by which an individual’s pupils trigger neurophysiological responses within an observer: when interacting partners synchronously dilate their pupils, humans come to feel reflections of the inner states of others, which fosters trust formation.
Autonomous task sequencing in a robot swarm
Lorenzo Garattoni & Mauro Birattari
Science Robotics, July 2018
Abstract:
Robot swarms mimic natural systems in which collective abilities emerge from the interaction of individuals. So far, the swarm robotics literature has focused on the emergence of mechanical abilities (e.g., push a heavy object) and simple cognitive abilities (e.g., select a path between two alternatives). In this article, we present a robot swarm in which a complex cognitive ability emerged. This swarm was able to collectively sequence tasks whose order of execution was a priori unknown. Because sequencing tasks is an albeit simple form of planning, the robot swarm that we present provides a different perspective on a pivotal debate in the history of artificial intelligence: the debate on planning in robotics. In the proposed swarm, the two robotics paradigms — deliberative (sense-model-plan-act) and reactive (sense-act) — that are traditionally considered antithetical coexist in a particular way: The ability to plan emerges at the collective level from the interaction of reactive individuals.
