Humans display a reduced set of consistent behavioral phenotypes in dyadic games.

ABSTRACT: Socially relevant situations that involve strategic interactions are widespread among animals and humans alike. To study these situations, theoretical and experimental research has adopted a game theoretical perspective, generating valuable insights about human behavior. However, most of the results reported so far have been obtained from a population perspective and considered one specific conflicting situation at a time. This makes it difficult to extract conclusions about the consistency of individuals' behavior when facing different situations and to define a comprehensive classification of the strategies underlying the observed behaviors. We present the results of a lab-in-the-field experiment in which subjects face four different dyadic games, with the aim of establishing general behavioral rules dictating individuals' actions. By analyzing our data with an unsupervised clustering algorithm, we find that all the subjects conform, with a large degree of consistency, to a limited number of behavioral phenotypes (envious, optimist, pessimist, and trustful), with only a small fraction of undefined subjects. We also discuss the possible connections to existing interpretations based on a priori theoretical approaches. Our findings provide a relevant contribution to the experimental and theoretical efforts toward the identification of basic behavioral phenotypes in a wider set of contexts without aprioristic assumptions regarding the rules or strategies behind actions. From this perspective, our work contributes to a fact-based approach to the study of human behavior in strategic situations, which could be applied to simulating societies, policy-making scenario building, and even a variety of business applications.

Project description:Background: Understanding how pretend play is related to positive emotions is important for supporting children's development and promoting their wellbeing. However, previous studies have mainly examined this association at individual levels and overlooked the potential links at interpersonal levels. This is an important knowledge gap because pretend play is commonly performed in social contexts. The current study investigates how peer pretend play is associated with children's display of positive emotions at both individual and dyadic levels. Methods: One hundred and eight Chinese children (M age = 8.95 years, SD = 0.99, 51.9% girls) were observed playing in peer dyads with toys. An interaction of 10 min was coded for each child's pretend play behavior, social and emotional pretend play themes, and display of positive emotions. Multilevel modeling was used to examine age and gender differences in peer pretend play. Actor-Partner Interdependence Models (APIM) were estimated to test the hypothesized associations between dyadic pretend play and children' display of positive emotions. Results: Compared to children whose playmates engaged in less pretend play, children whose playmates engaged in more pretend play were more likely to display positive emotions (p = 0.021). Additionally, children's display of positive emotions was predicted by both their own (p = 0.027) and their playmate's (p = 0.01) pretend play with emotional themes. Compared to younger children, older children were less likely to engage in pretend play (p = 0.002), but more likely to engage in pretend play with social themes (p = 0.03) when the total frequency of pretend play was controlled for. Boys were 4.9 times and 2.16 times as likely as girls to create aggressive pretend themes (p < 0.001) and non-aggressive negative pretend themes (p = 0.007), respectively. No significant gender differences were found in positive pretend themes. Conclusions: Pretending with peers may increase not only children's own, but also their play partner's display of positive emotions. Pretend play may not simply decline in middle childhood as previously assumed.
