Prevailing theories propose that confidence in two-alternative forced-choice decisions is based on the probability that the selected option is correct. However, recent findings from three-alternative tasks suggest that adults’ confidence might irrationally reflect the difference between the probabilities of the best and next-best options only, with other options disregarded. Using a novel probability task (in which participants guess the colour of a ball to be randomly selected from varying distributions) and a uniquely sensitive confidence measure, we investigated metacognition in multi-option decision making in children (N = 97, aged 6-9-years) and adults (N = 51). Contrary to previous findings, children’s and adults’ confidence was primarily explained by the probability of the best option. However, preliminary findings suggest that among older children and adults, additional irrelevant factors also accounted for unique variance in confidence. In some contexts, human confidence might be initially calibrated rationally but increasingly reflect irrational factors over development.

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

Humans have increasing opportunities to offload internal cognitive demand, such as by setting reminders to aid future memory performance. Here, we examine how children begin to balance mind and world: weighing up when to offload cognition and when to rely on their unaided capacities. Australian children aged 6 to 9 years (N = 120) were tasked with remembering the locations of 1, 3, 5, and 7 targets hidden under 25 cups. In the critical test phase, children were provided with a limited number of ‘tokens’ to distribute across trials, which they could use to mark target locations and assist future performance. Following the final search period, children were invited to evaluate and adjust their initial allocation. Results showed that 8- to 9-year-olds prospectively allocated proportionately more tokens to difficult trials, whereas 6- to 7-year-olds did so only in retrospect. Throughout childhood, humans become increasingly adept at balancing internal and external cognition.

Children’s Emerging Ability to Balance Internal and External Cognitive Resources

Social interaction plays a key role in children's development of language structure and use. In particular, children must successfully navigate the complex task of coordinating their communicative intents with people around them in early conversations. This study leveraged advanced NLP techniques to analyze a large corpus of child-caregiver conversations in the wild, combining methods for communicative intent inference and for turn contingency evaluation. Key findings include the prevalence of classic adjacency pairs like question-response; caregivers initiated the overwhelming majority of these sequences. We also document new developmental shifts in intent expression and an interesting dissociation between frequency vs. well-coordinated use across the early years of development. This framework offers a new approach to studying language development in its naturalistic, social context.

Analysing Communicative Intent Coordination in Child-Caregiver Interactions

What drives lexical alignment in the context of language emergence? We test the theory that limited context promotes alignment, because individuals cannot make use of iconic mappings between shared meanings and forms. Using a novel referential communication paradigm where participants use pre-recorded gesture videos to communicate, we test different context conditions. We find, unexpectedly, no alignment differences between dyads with shared context and dyads with limited context, even though the former have fewer communicative errors. Importantly, we do observe differences when it comes to the iconic strategies used: less shared context promotes the use of (shared) visual iconicity.

Shared context and lexical alignment: an experimental investigation

Despite decades of study, we still know less than we would like 
about the association between joint attention (JA) and language 
acquisition. This is partly because of disagreements on how to 
operationalise JA. In this study, we examine the impact of applying 
two different, influential JA operationalisation schemes to the same 
dataset of child-caregiver interactions, to determine which yields a 
better fit to children’s later vocabulary size. Two coding schemes—
one defining JA in terms of gaze overlap and one in terms of social 
aspects of shared attention—were applied to video-recordings of 
dyadic naturalistic toy-play interactions (N=45). We found that JA 
was predictive of later production vocabulary when operationalised 
as shared focus (study 1), but also that its operationalisation as 
shared social awareness increased its predictive power (study 2). 
Our results emphasise the critical role of methodological choices in 
understanding how and why JA is associated with vocabulary size.

Why does Joint Attention Predict Vocabulary Acquisition? The Answer Depends on What Coding Scheme you Use

Children rapidly learn to use language to effect a variety of communicative acts, such as proposing actions, asking questions, and making promises. While prior work has characterized this development in cross-sectional corpora, these analyses have been unable to comprehensively track individual differences in children's acquisition of communicative acts. We analyzed a longitudinal corpus of parent-child interactions from ages 14 to 58 months. We find that children's repertoires of communicative acts diversify over this period, with stable individual differences in the diversity of children's communicative act repertoires. Further, the diversities of parents' and children's communicative act repertoires are correlated. Children with more diverse communicative act repertoires also have larger vocabularies and use more diverse syntactic frames, suggesting links between discourse development and lexical and syntactic knowledge. Taken together, this work provides new insight into individual trajectories of communicative development and connections between communicative act use and other levels of language structure.

A longitudinal analysis of children's communicative acts

Dyadic social interaction is a complex coordination task involving a large number of interconnected variables. Previous research has shown that metastability -- persistence for an extended,  but impermanent, period of time in a non-stable state of a system -- can be a useful lens for understanding what makes an interaction successful. However, this framework has thus far only been applied to para-conversational signals like heart rate and prosody -- not to the semantic content of a conversation. Here, we present pink noise analysis of semantic trajectories as a metric for conversational success and apply this technique to a large open conversation dataset. Our results demonstrate that pink noise in a conversation predicts a host of variables representing participants' perception of  conversation quality. These results have implications for optimizing a whole host of difficult dyadic conversations -- like those between political partisans -- and human-computer interactions, with applications for improving large language models' adaptability.

Pink noise in speakers' semantic synchrony dynamics as a metric of conversation quality

There is considerable debate about the origin, mechanism, and extent of humans’ capacity for recursive mindreading: the ability to represent beliefs about beliefs about beliefs (and so on). Here we quantify the extent to which language exposure could support this ability, using a Large Language Model (LLM) as an operationalization of distributional language knowledge. We replicate and extend O’Grady, et al. (2015)’s finding that humans can mindread up to 7 levels of embedding using both their original method and a stricter measure. In Experiment 2, we find that GPT-3, an LLM, performs comparably to humans up to 4 levels of embedding, but falters on higher levels, despite being near ceiling on 7th-order non-mental control questions. The results suggest that distributional information (and the transformer architecture in particular) can be used to track complex recursive concepts (including mental states), but that human mentalizing likely draws on resources beyond distributional likelihood.

Learning traps are false beliefs that entrench themselves by discouraging the exploration required to correct them. In previous lab experiments, these learning traps have proven remarkably difficult to prevent. Here, we investigate whether learning traps remain stable in contexts in which both individual and social learning are possible. In two of our three experiments, we found that learners trapped by a false belief were significantly more likely to escape a learning trap when they were able to observe another decision-maker's choices (without observing their outcomes). However, social learning was not a panacea. Social learning was constrained by the challenge of inferring others' beliefs, and trapped learners struggled to learn from partners with sub-optimal decision rules, even when their partner's choices were informative. Collectively, these results suggest that while social learning can help overcome the limits of individual learning, learning from others comes with its own challenges and limitations.

How does social learning affect stable false beliefs?

Disparate impact rules are formally neutral but indirectly discriminate against protected groups (i.e., by targeting a characteristic that is more prevalent in a given group). Because these rules are not obviously malicious, they have been widely enacted to circumvent policies against explicit discrimination. In a series of four experiments, we show that adults and children are sensitive to the moral implications of disparate impact rules. However, we also find that they are more accepting of these rules when strong justification is provided, compared to rules with no justification. Crucially, demographic differences also impact people's judgments of disparate impact rules and their creators. We find that conservatives and those from groups not directly affected by the rule tend to be more accepting of it. By studying people's reasoning about disparate impact rules, this work aims to identify the mechanisms by which these rules may evade detection. Finally, we discuss how these insights may inform the development of interventions that highlight the problematic effects of indirectly discriminatory policies.

The Hair Club for Boys: How children and adults judge disparate impact rules

Spatial demonstratives are deictic expressions used to point to a referent with language. In the standard view, they encode a spatial proximal\distal contrast between “near” (this) and “far” (that) from the speaker. Several studies have shown that such contrast maps on a perceptual contrast between peripersonal and extrapersonal space. Still, other factors beyond spatial distance influence demonstrative choice. Here we investigate whether the proximal/distal contrast maps also onto a more general contrast between being in physical control/not in control of a target referent. Participants were presented with two circles (red and blue) on a screen. They had to move them with the mouse to find the target circle (the one with two gaps). One circle followed the mouse trajectory (controllable), while the other moved randomly in the center of the screen (not controllable). Unknown to the participants, the gaps only appeared if the stimuli crossed a distance threshold. Importantly, participants had to use stimulus controllability to solve the task. They were instructed to answer by indicating the target to the experimenter using this/that and red/blue (in Italian questo/quello and rosso/blu). Results show that participants used the proximal demonstrative more frequently to refer to the target stimulus when in control. These findings suggest that, similarly to spatial distance, physical control influences demonstrative choice.
