How people reach consensus in social networks with locally distributed interactions is relevant to understanding collective group decision-making, problem-solving, and voting. However, while the importance of theory of mind in consensus problems has been hypothesized, little work has been done to test it systematically. We present both computational modeling and behavioral experiments designed to test the impact of theory of mind on individual choices within such consensus networks. We test 2,108 computational models informed by theoretical work on a graph-coloring consensus task to compare models using theory of mind to other behavioral parameters. We then use behavioral responses from 107 participants in a similar task to evaluate support for theory of mind in consensus formation. We find that the computational model that best accounts for prior behavioral data uses theory of mind, and our behavioral results likewise support use of theory of mind over other potential decision-making models.

The 46th Annual Meeting of the Cognitive Science Society presents the latest research across cognitive science and highlights the theme of Cognition in Context.

Do decision makers’ strategies of integrating different risks depend on framing? In the present study, participants were either instructed that they were choosing between two solutions to a complex problem or between two generic options. The former was framed as an industrial scenario that required choices between modifying and replacing a module (Adapt or Exchange). The risk was higher for Adapt to harm the product and for Exchange to harm the plant. Participants were either told that the consequences of both risks were equally severe (content-same group), or that harming the plant was worse (content-different group). A third group received a generic task framing (no-content group). We expected framing to affect risk integration, inducing different choices and strategies in the content-same than the no-content group. The data refuted this hypothesis, but decisions clearly diverged from the content-different group. These findings question whether ecological validity can be enhanced merely by framing.

Adapt/Exchange decisions or generic choices: Does framing influence how people integrate qualitatively different risks?

Trust is an important factor in interaction with automated agents. This study tracks users’ trust calibration to automated agents in a vocabulary learning task. We hypothesize that trust declines as agent reliability declines and that anthropomorphism should buffer against this decline.
Replicating de Visser et al. (2016), 60 participants guessed the meaning of 96 foreign words in a 4x4x2 mixed experiment. In each trial, they guessed alone, then got an agent’s recommendation and gave trust judgments, and made a final decision. Four pedagogical agents varying in anthropomorphism (within-subject: human, robot, smart speaker, computer) recommended answers with decreasing reliability (within-subject: 100%, 67.5%, 50%, 0%). Furthermore, participants either did or did not watch an introductory video about the agents (between-subject). Behavioral and judgment data were analysed via mixed-effects models and ANOVAs. Two-way interaction shows that trust declined differently in various agents, but there is little evidence supporting trust resilience in any agent.

Trust Resilience in Pedagogical Agents: Will Anthropomorphism Help Against Trust Decline?

People solve a myriad of coordination problems without explicit communication every day. A recent theoretical account, virtual bargaining, proposes that, to coordinate, we often simulate a negotiation process, and act according to what we would be most likely to agree to do if we were to bargain. But very often several equivalent tacit agreements — or virtual bargains — are available, which poses the challenge of figuring out which one to follow. Here we take inspiration from virtual bargaining to develop a cognitive modeling framework for dynamic coordination problems. We assume that players recognize their common goal, identify one or more possible tacit agreements based on situational features, observe the history of their partner’s choices to infer the most likely tacit agreement, and play their role in the joint plan. We test this approach in two experiments (n = 125 and n = 133) based on a dynamic coordination game designed to elicit agreement-based behavior. We fit our model at the individual level and compare its performance against alternative models. Across four different conditions, our model performs best among the set of models considered. Behavioral results are also consistent with players sustaining coordination and cooperation in the task by converging on tacitly agreed strategies or “virtual bargains”.

Coordination in dynamic interactions by converging on tacitly agreed joint plans

Humans can learn from observing diverse others, even when they know little about their exact preferences, skills, or goals. Yet, while our remarkable social learning abilities have been a popular research topic, prior work has generally been limited to tasks in which observer and demonstrator share the same value function. 
To address this discrepancy, we use the socially correlated bandit task, where participants explore positively correlated, rather than identical, environments in groups. We extend existing work using this paradigm by comparing behaviour across individual and social rounds within participants.
We replicate findings that humans are able to use correlated social information effectively, with behaviour being best described by a model noisily integrates social information. In comparing individual and social search behaviour, we find that social learning partially replaces directed exploration. In conclusion, we find that humans use social information flexibly, employing it as an exploration tool, despite our differences.

Social learning functions as an exploration tool in correlated environments

Commitment is a defining feature of human rationality. This study explores a social origin of spontaneous intentional commitment, assuming commitment in individual decision-making arises from an internalized self-presentation, transferring the audience of commitment from a real partner to an inner eye perspective. To test this "social inner eye" hypothesis, we exposed participants to different social contexts while maintaining the individual nature of the task. Across three experiments, we found that (a) individuals consistently showed stronger commitment when acting in front of others, (b) different social contexts had different impacts on the process of commitment formation, with the mere outside observer accelerating commitment, while a parallel player delays it, (c) participants spontaneously coordinated their intentions to avoid conflicts when playing with another parallel player, despite no coordination was required. Taken together, we demonstrated how social context influences the strength, content, and timing of individual commitment.

Intentional commitment as a spontaneous presentation of self

There has been considerable interest exploring how the utility of an outcome impacts the probability with which it is mentally simulated. Earlier studies using varying methodologies have yielded divergent conclusions with different directions of the influence. To directly examine such mental process, we employed a random generation paradigm in which all the outcomes were either equally (i.e., followed a uniform distribution) or unequally (i.e., a binomial distribution) probable. While our results revealed individual differences in how the utility influenced responses, the overall findings suggested that it is the outcomes' probabilities, not their utilities, that guide this process. Notably, an initial bias emerged, with individuals displaying a tendency to start with smaller values when all outcomes are equally likely. Our findings offer insights into the benefits of studying the mental sampling processes and provide empirical support for particular sampling models in this domain.

Probability, but not utility, influences repeated mental simulations of risky events

Whether logical inference is available without language is highly debated. One such inference is the disjunctive syllogism (A Or B, Not A, Therefore B). Evidence from non-linguistic search tasks suggests that that the syllogism may be unavailable before age 3 (Mody & Carey, 2016). However, in a replication of the same task using language (i.e., verbal negation), even 2.5-year-olds succeeded (Grigoroglou, et al., 2019). Here we explore the role of language in children’s logical reasoning. 2.5-, 3- and 4-year-olds performed a non-linguistic search task, after a short training in reasoning by exclusion. Half of the children received linguistic training (e.g., heard “there is no coin in X cup”); half received non-linguistic training (i.e., saw that one location was empty). Results show that 2.5-year-olds who received linguistic training succeeded in disjunctive syllogism but those who received non-linguistic training failed. We conclude that the presence of verbal negation facilitated logical reasoning.

Efficient cognitive algorithms enhance problem-solving in many cognitive domains but can be difficult to discover and use. Classical studies of seriation suggest that children struggle to apply algorithmic strategies in a simple sorting problem, yet it remains unclear why. We examined children's solutions to a modified variant of the sorting problem in which object ranks were hidden. Children independently discovered at least two efficient algorithmic solutions to this problem. Older children were more efficient sorters.

Children spontaneously discover efficient sorting algorithms in a seriation task

Spatial abilities and their developmental trajectory are an important part of human intelligence and have been the subject of numerous studies, including mental rotation and perspective taking. However, little is known about these processes in under-represented populations. Here we report a study on 10-year-old children in such a context who participated in four spatial tasks – animal picture mental rotation, abstract figures mental rotation, memory for object location, and picture perspective taking. Results revealed no male advantage on any task, and better performance in the abstract figures task for girls following an alternative school program in mathematics. Furthermore, the analysis found no correlation between the mental rotation and perspective taking performance. Research on under-represented populations is an important drive towards greater generalizability of findings and conclusions

The Role of Gender and Curriculum in Mental Rotation & Perspective Taking

Learned fears of stimuli from phylogenetically fear-relevant categories (such as snakes and spiders) tend to be significantly more resistant to extinction than those from fear-irrelevant categories (such as birds and butterflies.) Olsson et al. (2005) demonstrated that representations of outgroup members, as defined by race, can act as fear-relevant stimuli in a classical conditioning paradigm. It is not as clear, however, whether (and how) persistent fear of outgroup members can be acquired vicariously. We investigate whether observers of interactions with negative outcomes associated with representations of outgroup members develop extinction-resistant fears. Our results indicate that outgroup members can act as fear-relevant stimuli in an observational scenario. The effect is not sensitive to self-relevance manipulations; importantly, however, other-oriented empathy may reduce the tendency toward forming extinction-resistant conditioned responses to outgroup members. Implications of these preliminary results, including limitations and suggestions for future research, are discussed.
