Social norms are a hallmark of human social intelligence, yet the reasoning processes involved in norm formation have been difficult to capture with traditional modeling frameworks. We developed a computational model of norm formation as joint planning via theory-of-mind. The model is designed to capture the distinctively human ability to flexibly develop more complex norms in more complex situations, via simulation of joint decision-making with other agents over an extended time horizon. We evaluated the predictions of the model against participant interactions in a 2-player iterated decision-making task. Across 3 conditions our model captured the way participants balanced joint reward, fairness, and complexity when forming norms.

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

People often select only a few events when explaining what happened. What drives people’s explanation selection? Prior research argued that people’s explanation choices are affected by event normality and causal structure. Here, we propose a new model of these existing findings and test its predictions in a novel experiment. The model predicts that speakers value accuracy and relevance. They choose explanations that are true, and that communicate useful information to the listener. We test the model’s predictions empirically by manipulating what goals a listener has and what actions they can take. Across twelve experimental conditions, we find that our model accurately predicts that people like to choose explanations that communicate optimal interventions

Do as I explain: Explanations communicate optimal interventions

Speakers are often over-informative, referring to the color and shape of a referent even when all objects in a scene are unique. Interestingly, this helps listeners locate the target. If speakers are indeed sensitive to listeners’ online processing demands, they should be more over-informative when addressing someone whose processing is especially slow. Here we show that English-speaking adults produce more redundant color adjectives when speaking to children than adults (Exp 1); that although Spanish-speakers produce fewer redundant color adjectives than English-speakers overall, they too do so more often for children (Exp 2); that these results are independent of experience with young children (Exp 3), and that children themselves (ages 4-10) are more over-informative when speaking to younger children than adults (Exps 4 and 5). Collectively, these results suggest that sensitivity to listeners’ online processing demands is robust, emerges early in development, and may be especially tailored to young learners.

Brown Bear, Brown Bear, what do you see? Speaker use more redundant color adjectives when speaking to children than adults

Recent research has provided experimental support for a new ``Inferentialist'' theory of conditionals, challenging the Equation P(If A, C) = P(C | A) and theories that support it. The key evidence comes from probability judgments involving conditionals whose antecedent and consequent are relevant vs. irrelevant to each other. Expanding on recent experimental work, we argue that Inferentialism has difficulty explaining the data. However, theories that support The Equation theory are well-placed to account for the results once we recognize an independent phenomenon of pragmatic intrusion on probability judgment - in this case, participants' tendency to assign lower probability to conditionals that are pragmatically incoherent.

Pragmatic intrusion in probability judgment: The case of conditionals

Generic statements (e.g., “girls wear makeup”) tie properties to groups and are a common way of transmitting stereotypes. One natural but untested way that people might try to undermine these statements is by making a similar statement about salient but not mentioned contrastive groups (e.g., “boys can wear makeup too”). Do can generics license the same judgments as do generics? Four studies examined how adults judge two novel groups when one group does a property (e.g., Zarpies make pizzas) while the other group can do the property (e.g., Gorps can make pizzas too). Compared to do generics, adults consistently judged groups described with can generics to be less likely to have, less interested in, less competent at, and for it to be less permissible for them to do the property. Overall, these results suggest that can generics are unlikely to be an effective means at equating beliefs about two groups.

Not all generics are created equal: Differentiating between ‘do’ and ‘can’ generic statements

This study examines the development of children's gaze during face-to-face conversations, following up on previous work suggesting a protracted development in attending to the interlocutor's face. Using recent mobile eye-tracking technology, we observed children interacting with their parents at home in natural settings. In contrast to previous work, we found that children, even in early middle childhood, exhibit adult-like gaze patterns toward the interlocutor. However, differences emerge in gaze allocation between speaking and listening roles, indicating that while children may focus on faces similarly to adults, their use of gaze for social signaling, such as turn-taking cues, may still be maturing. The work underscores the critical role of social context in understanding the development of non-verbal behavior in face-to-face conversation.

Child-Caregiver Gaze Dynamics in Naturalistic Face-to-Face Conversations

Toddlers are sensitive to the reliability of speakers in their environment \cite{koenig2010}.
While previous work suggests that children prefer labels from reliable speakers, it remains unclear how these social representations guide lower-level information-seeking processes that affect speaker preferences. The current study introduces a gaze-contingent eye-tracking paradigm to investigate how children engage in sampling during word learning. Toddlers (22-24m) view videos of two speakers labeling familiar objects; one speaker provides reliable labels and the other speaker provides unreliable labels. Toddlers then sample novel labels from the speakers using a gaze-contingent interface: only the speaker they are fixating on provides a novel label. Preliminary data (N = 18) suggests that participants prefer to sample first from the reliable speaker over the unreliable speaker. However, there is little difference in overall sampling preferences. Our findings suggest that toddlers can assess speaker reliability, but remain open to exploring information from unreliable speakers.

Toddlers Actively Sample from Reliable and Unreliable Speakers

A wealth of evidence indicates that children use their developing linguistic knowledge to incrementally interpret speech and predict upcoming reference to objects. For verbs, determiners, case-markers, and adjectives, hearing linguistic information that sufficiently constrains referent choice leads to anticipatory eye-movements. There is, however, limited evidence about whether children also use spatial prepositions predictively. This is surprising and theoretically important: spatial prepositions provide abstract semantic information that must interface with spatial properties of, and relations between, objects in the world. Making this connection may develop late because of the complex mapping required. In a visual-world eye-tracking task, we find that adults and 4-year-olds hearing 'inside' (but not 'near') look predictively to objects that afford the property of containment. We conclude that children make predictions about the geometric properties of objects from spatial terms that specify these properties, suggesting real-time use of language to guide analysis of objects in the visual world.

A Look “Inside” Children’s Real-time Processing of Spatial Prepositions

Do children reason that people in close relationships accurately represent each other’s minds? In two experiments (total N = 123), we found that 7- to 9-year-old children from the US (i) reason that people who are close will accurately represent each other’s goals and desires and (ii) infer that people are socially close when they accurately predict each other’s emotional states. These findings suggest that children reason flexibly about mental state attributions within close relationships.

Children Expect People to Accurately Represent the Minds of Their Close Social Partners

We study referential communication about concepts at different levels of abstraction in an interactive concept-level reference game. To better understand processes of abstraction, we investigate superordinate referring expressions (animal). Previous work identified two main factors that influence speakers’ choice of referring expressions for concepts: the immediate context and the basic-level effect, i.e. a preference for basic-level terms such as dog. Here we introduce a new concept-level reference game that allows us to study differences in the basic-level effect between comprehension and production and to elicit superordinate referring expressions experimentally. We find that superordinate referring expressions become relevant for groups of objects. Further, we reproduce the basic-level effect in production but not in comprehension. In conclusion, even though basic-level terms are most readily accessible, speakers tailor their expressions to the context, allowing the listener to identify the target concept.

Superordinate referring expressions in abstraction: Introducing the concept-level reference game

Adults often learn new semantic information in face-to-face communication with other adults (e.g., teachers, colleagues). More knowledgeable individuals provide an ensemble of multimodal behaviours that can shape the information that their interlocutors learn. Using the naturalistic ECOLANG corpus of dyadic conversations, we ask whether multimodal behaviours (pitch, speaking rate, representational gestures, points, object manipulations, and gaze) support adults’ semantic learning of unknown objects above and beyond verbal properties of utterances (number of utterances, lexical diversity, mean length of utterances, concreteness) and learners’ individual differences (vocabulary, working memory). We found that individual differences, pointing and object manipulations affected learning, with verbal and multimodal factors also interacting to predict adult semantic learning. Our results highlight the relevance of accounts of multimodal learning in adulthood and the importance of considering naturalistic interaction in its complexity to understand the factors that influence adult learning.
