Artificial neural networks trained using deep-learning methods to solve a simple reference game by optimizing a task-specific utility develop efficient semantic categorization systems that trade off complexity against informativeness, much like the category systems of human languages do. But what exact type of structures in the semantic space could result in efficient categories, and how are these structures shaped by the contexts of communication? We propose a NN model that moves beyond the minimal dyadic setup and show that the emergence of convexity, a property of semantic systems that facilitates this efficiency, is dependent on the amount of variability in communication contexts across partners. We use a method of input representation based on compositional vector embeddings that is able to achieve a higher level of communication success than regular non-compositional representation methods, and can achieve a better balance between maintaining the structure of the semantic space and optimizing utility.

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

Human cognition is highly flexible– even when posed with novel questions and situations, we are able to manipulate existing knowledge to draw reasonable conclusions. All human cognition requires flexibility, yet we lack a well-justified computational explanation for how humans might learn and manipulate conceptual knowledge in a way that allows for cognitive flexibility. Here, we develop and test a novel model of concept learning that has roots in multitask learning and multidimensional scaling. In contrast to previous models of concepts, which are often defined through a single-task learning mechanism, our multitask learning model frames concepts as latent vector representations that are learned through observations across multiple task domains. Testing using simulated data shows that our multitask model is capable of generalizing knowledge across tasks, and additionally may also generalize better than single-task models within tasks. Our results so far support a multitask learning framework for capturing concept learning and generalization ability.

A multitask model of concept learning and generalization

The discrete entities of symbolic systems and their explicit relations make symbolic systems more transparent and easier to communicate. This is in contrast to neural systems, which are often opaque. It is understandable that psychologists often pursue interpretations of human cognition using symbolic characterizations, and it is clear that the ability to find symbolic variables within neural systems would be beneficial for interpreting and controlling Artificial Neural Networks (ANNs). Symbolic interpretations can, however, oversimplify non-symbolic systems. This has been demonstrated in findings from research on children’s performance on tasks thought to depend on a concept of exact number, where recent findings suggest a gradience of counting ability in children’s learning trajectories. In this work, we take inspiration from these findings to explore the emergence of symbolic representations in ANNs. We demonstrate how to align recurrent neural representations with high-level, symbolic representations of number by causally intervening on the neural system. We find that consistent, discrete representations of numbers do emerge in ANNs. We use this to inform the discussion on how neural systems represent quantity. The symbol-like representations in the network, however, evolve with learning, and can continue to vary after the neural network consistently solves the task, demonstrating the graded nature of symbolic variables in distributed systems.

Symbolic Variables in Distributed Networks that Count

How does globalization impact the interaction between perception and language? Building on Berlin and Kay's foundational study of color naming, we recruited 2,280 online participants speaking 22 different languages. We show that color naming maps differ structurally across languages, even among internet users living in (mostly) industrial societies. We use Large Language Models (LLMs) to simulate the limits of globalization by reproducing the naming task with a highly multilingual artificial agent with access to global digital information. We show that while the LLM has access to all languages, it has language-specific color representations and the number of color terms is correlated across humans and LLMs. However, LLMs use more color terms than humans, indicating differences in the representation. These results suggest that globalization has not removed cultural distinctions in color concepts, as language continues to be a key factor in the diversity of perception and meaning.

Studying the Effect of Globalization on Color Perception using Multilingual Online Recruitment and Large Language Models

Drift-Diffusion Models (DDMs) are a widely-used class of models that assume an accumulation of evidence during a quick decision. These models are often used as measurement models to assess individual differences in cognitive processes, such as an individual’s evidence accumulation rate and response caution. An additional underlying assumption of these models is that there is internal noise in the evidence accumulation process. However, fitting DDMs to experimental choice-response time data alone cannot yield estimates of an individual's evidence accumulation rate, caution, and internal noise at the same time. This is due to an intrinsic joint-unidentifiability of these parameters when fitting DDMs to behavioral data. We introduce methods of estimating these parameters at the same time with additional data types. The methods to estimate model parameters rely on Bayesian inference and simulation-based Bayesian inference. We show why these methods are useful without making strong assumptions.

Using additional data types to identify the unidentifiable components of cognition during decision-making

It has been suggested that humans mentally simulate the outcomes of their actions when making decisions. However, this process can be challenging in real-world decision-making, which typically involves temporally extended decision trees with numerous potential outcomes. Here, we demonstrate with a computational model that temporally extended decisions can be achieved with just a few forward simulations, formalized as rollouts. We also show that, under resource constraints, performing many partial (shallow) rollouts can yield more favorable outcomes than performing fewer full (deep) rollouts. Additionally, our model captures behaviors traditionally attributed to reflexive pruning or satisficing strategies without the need for explicit heuristics, providing an alternative explanation for these phenomena. Finally, we show that the dynamics of value estimation over successive rollouts closely resemble evidence accumulation models. Our framework offers a plausible mechanism for temporally extended decision-making and provides insights into the neural underpinnings underlying this process.

Some and Done? Temporally extended decisions with very few rollouts

Emotions can be insensitive to certain attributes of a situation. A large body of evidence shows that information on probabilities, large numerical counts, or intentions is frequently disregarded in the elicitation and regulation of emotions. To date, no existing theory comprehensively accounts for the features that tend to be overlooked by emotion. I call attention to the common denominator of such features: they cannot be perceived nor contribute to the iconic representation of events. For instance, the exceedingly low probability of a plane crash does not affect its imagistic representation (i.e., the iconic representation of the event is silent about the event’s probability). I introduce the Iconic Prioritization Hypothesis, positing that the prioritization of the iconic format in emotion can explain the neglect of information that is representationally silent in this format. Emotion may favour iconicity as it is the format of immediate, first-hand evidence about our surroundings.

Iconic prioritization and Representational Silence in emotion

To investigate, in an ecological way, how people evaluate the truthfulness of universal and probabilistic statements we introduce a modified version of the Wason Selection Task. Participants see four decks of cards (instead of four cards), and are asked to turn as many cards as they deem necessary to judge if a given statement is true or false, both for the observed sample (deductive task) and for an imaginary reference population (inductive task). Participants encounter universal (“All P are Q”) or probabilistic statements (“more/less than x% of P are Q”; between-subjects) with abstract, realistic neutral, and realistic polarizing statements (within-subjects). Half of the participants receive an endowment for each turn, correct (incorrect) deductive judgments are rewarded (penalized), and turning a card incurs a cost (other half: fixed participation fee). We report results from two online experiments, thereby also contrasting prescriptive models of evidence search with actual behaviors.

The Wason selection task in the long-run: Evaluating the truthfulness of universal and probabilistic statements through evidence search

When making decisions, humans often rely on information from their social networks through a process termed social sampling. Prior work suggests that when drawing social samples, people search through their contacts in a sequential manner based on structured social categories (e.g., family vs. friends; online vs. offline contacts). We examined whether the problem domain impacts how one categorizes their social contacts and which social categories they sample from. In our study, participants answered questions about the relative popularity of either national parks or social media platforms, respectively associated with offline activities (e.g., visit a national park) and online activities (e.g., use an online social media platform). Participants then provided frequency information about the number of their contacts who have visited the parks or used the social media platforms in different social groups. Adopting a hierarchical Bayesian modeling approach, we compared two social sampling models: one defining social groups based on closeness of social relations (i.e., family, friends, acquaintances), and one using social groups based on contact mode (i.e., online vs. offline contacts). Results indicate that when making comparison judgments related to online activities (social media usage), participants are more likely to sample from social circles of online contacts, and when judgments are related to offline activities (national park visits), they are more likely to sample from social circles of offline contacts. These findings suggest that people sample from different members of their social network depending on the type of decision they are making.

Social Sampling in Decision Making for Online and Offline Activities

Developmental psychologists have often turned to children to clarify understanding of functional and mechanistic cognition. Here, we investigate children’s epistemic inferences of function – what a thing is for – and mechanism – how a thing works. Children, like adults, believe a mechanism-knower knows more than a function-knower (Study 1). Yet, unlike adults, children do not expect that a mechanism-knower is also more likely to know function than a function-knower is to know mechanism (Study 2). Children’s experience of learning function and mechanism of complex systems sheds light on this asymmetry; Children who are taught just mechanism can infer the complementary function, but, interestingly, children who are taught just function can likewise infer the complementary mechanism (Study 3). This paper considers the nature of children’s epistemic intuitions and whether those beliefs are reflective of children’s learning experience.

Children’s unexpected inferences across knowledge types

Engaging in science lessons requires creative thinking skills. These skills are expressed in the verbalized ideas of students during these activities. The objective of this study was to analyze how momentary teacher behavior is associated with the level of novelty of scientific reasoning in teacher-student interactions. Participants were 14 teachers together with a small teaching group of 4-7 year old students (around 64 students in total). One lesson per teacher was recorded prior to a professional intervention. We categorized the verbalizations of both teachers and students in real-time, assessing level of novelty for all student statements and categorizing teacher utterances as divergent, convergent, or neutral. Sequential analyses showed that interaction patterns are specific for each teacher and class. Generally, students tended to express lower levels of novelty following teachers' convergent statements. However, teachers' divergent statements did not lead to higher levels of student novelty.
