As mental representations are standardly thought to underlie all cognitive processes, a major goal of cognitive science has been to uncover representations. Methods for representation learning from behavioral data often model choice or reaction time data alone, but not jointly, leaving out potentially useful information. Here we develop two models of choice and RT in the odd-one-out task, including one based on the Linear Ballistic Accumulator. Parameter recovery simulations show joint modeling of choice and RT with LBA recovers representations more accurately than modeling choice alone with softmax. However, on two empirical datasets of images and words, joint models performed no better than choice-only models, despite a significant correlation of reaction time with two measures of similarity and choice difficulty in both datasets. We speculate on reasons for the unrealized promise of joint modeling of RT and choice in representation learning.

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

This study introduces an innovative approach to readability assessment, integrating cognitive science principles with artificial intelligence to evaluate text comprehensibility. Traditional methods of determining text readability have largely focused on surface-level features, neglecting educational complexity and curriculum alignment of the content. This study proposes a novel method that employs large language models (LLMs) to assess text difficulty by considering content depth and its alignment with educational standards. By leveraging the extensive knowledge encapsulated in LLMs, the method evaluates whether the content of the text corresponds to a specific educational level, ranging from elementary to university. Our readability assessment method provides a more nuanced understanding of text accessibility. The difficulty of the text content is assessed using a combination of language resources to measure the amount of scientific knowledge contained in the text. It promises to enhance educational resources' alignment with learners' capabilities, facilitating more effective learning experiences.

Advanced Readability Estimation through Educational Content Complexity

Language is fundamental in human cognition and communication, helping us to encode the world around us. Adjectives represent a linguistic form used extensively, particularly in the social domain. Adjectives vary in both their valence and their breadth (e.g., “punctual” is narrower than “dependable”). Variations in adjectival breadth have not been studied extensively but may have significant consequences across various domains. The present study explores how subtle distinctions in adjective use may relate to descriptions of experiences that people share. To assess linguistic breadth in online communication, we examine whether online reviews with different star ratings are associated with differences in adjectival breadth. Through an analysis of over 200,000 reviews from Amazon digital music (Study 1) and Yelp restaurants (Study 2), we find evidence that linguistic desirability and breadth of adjectives in reviews positively correlate with their ratings. Specifically, higher-rated reviews tend to use broader and more desirable adjectives. However, this relationship varies between product categories, with high-rated music reviews showing increased linguistic breadth and desirability, while top-rated restaurant reviews demonstrate a decrease in breadth. This paper contributes to understanding linguistic breadth in social media contexts, highlighting how subtle language variations in evaluations can reflect different cognitive and communicative processes.

Large Language models (LLM) exhibit human-like proficiency in various tasks such as translation, question answering, essay writing, and programming. Emerging research explores the use of LLMs in collective problem-solving endeavors, such as tasks where groups try to uncover clues through discussions. Although prior work has investigated individual problem-solving tasks, leveraging LLM-powered agents for group consensus and decision-making remains largely unexplored. This research addresses this gap by (1) proposing an algorithm to enable free-form conversation in groups of LLM agents, (2) creating metrics to evaluate the human-likeness of the generated dialogue and problem-solving performance, and (3) evaluating LLM agent groups against human groups using an open source dataset. Our results reveal that LLM groups outperform human groups in problem-solving tasks. LLM groups also show a greater improvement in scores after participating in free discussions. In particular, analyses indicate that LLM agent groups exhibit more disagreements, complex statements, and a propensity for positive statements compared to human groups. The results shed light on the potential of LLMs to facilitate collective reasoning and provide insight into the dynamics of group interactions involving synthetic LLM agents.

Large Language Models for Collective Problem-Solving: Insights into Group Consensus Decision-Making

Phonological anticipation, the ability to predict forthcoming words based on phonological cues, plays a pivotal role in language processing (Brunellière et al., 2018; Ito et al., 2018). Although predictive language abilities have been observed in infants, the mechanisms and developmental trajectories within native Spanish-speaking populations remain underexplored. This study delves into the investigation of phonological anticipation in Mexican Spanish-speaking infants through the utilization of eye-tracking methodology. The objective is to ascertain whether infants across different age groups can anticipate phonologically related words within semantically restrictive sentences. To achieve this, auditory sentences such as "La gallina pone... huevos" (The hen lays... eggs) were presented, accompanied by visual stimuli that included both phonologically related ("hueso" - bone) and unrelated competitor ("calcetín" - sock). Results indicate that 18- and 24-month-olds did not exhibit anticipation based solely on semantics, necessitating the auditory presentation. However, 30-month-olds demonstrated phonological anticipation, signaling developmental changes.

Unveiling the Path to Phonological Anticipation: Insights from Infants' Eye Movements

We examine the role of referential contrast in the learning of homophone versus superordinate terms: when an unfamiliar word is mapped to a broad range of referents across learning instances, how do learners decide whether the word has distinct meanings or a single superordinate meaning? We hypothesize that learners can accomplish this via semantic contrast among candidate referents within the referential domains. Learners will be more likely to establish homophonous meanings when contrasting referents are from a neighboring category of the target, and more likely to establish a superordinate meaning when contrasting referents are from more distant categories. We also expect homophone learning to be more difficult because of their additional demands on learning and memory. Our predictions were borne out in a series of experiments and in a cross-situational model of word learning. Overall, this study offers new perspectives for how learners form hypotheses for novel word meanings.

Is it a bat or a thing? Referential contrast in the learning of homophones and superordinate terms

The current study used a real-time interactive “advisor-decider” task, in which advice given by one participant results in an onerous workload for another participant, to show that self-conscious affect based on performance in one domain shapes decisions to engage in prosocial behavior in an unrelated domain: Advisors that performed at or worse than the norm, in terms of giving incorrect advice, made more frequent subsequent charity donations. Intriguingly, when advisors were given social information about their performance relative to the norm, this pattern was reversed, such that advisors that performed worse than the norm made less frequent donations. We interpret this finding as reflecting a shift in the emotion driving the behavior, from guilt to shame. Consistent with this interpretation, trait measures of guilt proneness but not of shame proneness predicted an increase in both the probability and magnitude of donations.

Exogenous Self-Blame Modulates Charitable Giving

This study investigates the processing of structurally ambiguous relative clause (RC) constructions in Japanese by Persian-Japanese learners, examining the influence of their native language (L1) on second language (L2) processing. It challenges the universality of parsing strategies through a self-paced reading (SPR) task. The results indicate a preference for High Attachment (HA) and a stronger tendency towards NP-high when it's an animate noun, in both Persian and Japanese. Descriptive analyses further revealed a shift from Low Attachment (LA) to HA among native Japanese speakers, suggesting unforced revision. However, there was an absence of a clear animacy effect on their preference. These findings suggest parallel interactive mechanisms in sentence processing and the transfer of syntax and semantic information from L1 to L2. Moreover, the study underscores language-specific differences in sentence processing, emphasizing the impact of language dominance in cross-linguistic transfer and contributing to our understanding of bilingual sentence processing.

Processing of Relative Clause Structural Ambiguity by Iranians' Japanese Learners - From the Perspective of the Effect of L1 and the Animacy of the Head Nouns on L2 Sentence Processing -

Exploration in sequential decision problems is a computationally challenging problem. Yet, animals exhibit effective exploration strategies, discovering shortcuts and efficient routes toward rewarding sites. Characterizing this efficiency in animal exploration is an important goal in many areas of research, from ecology to psychology and neuroscience to machine learning. In this study, we aim to understand the exploration behavior of animals freely navigating a complex maze with many decision points. We propose an algorithm based on a few simple principles of animal movement from foraging studies in ecology and formalized using reinforcement learning. Our approach not only captures the search efficiency and turning biases of real animals but also uncovers longer spatial and temporal dependencies in the decisions of animals during their exploration of the maze. Through this work, we aspire to unveil a novel approach in cognitive science of drawing interdisciplinary inspiration to advancing the field's understanding of complex decision-making.

Temporal Persistence Explains Mice Exploration in a Labyrinth

Recent neuroscience studies suggest that the hippocampus encodes a low-dimensional ordered representation of evidence through sequential neural activity. Cognitive modelers have proposed a mechanism by which such sequential activity could emerge through the modulation of the decay rate of neurons with exponentially decaying firing profiles. Through a linear transformation, this representation gives rise to neurons tuned to a specific magnitude of evidence, resembling neurons recorded in the hippocampus. Here we integrated this cognitive model inside reinforcement learning agents and trained the agents to perform an evidence accumulation task designed to mimic a task used in experiments on animals. We found that the agents were able to learn the task and exhibit sequential neural activity as a function of the amount of evidence, similar to the activity reported in the hippocampus.
