Truth over falsehood
The English poet John Milton portrayed truth as a powerful warrior capable of defeating falsehood in open combat. The spread of false information online suggests otherwise. Here, we test the persuasive power and transmission potential of true versus false messages in a controlled experimental setting, free from the effects of social media algorithms and bot amplification. Across four experiments (combined N = 4,607), we tested how perceived verac…
Core Vocabulary in Language Representation and Processing
The question of which words are most important or fundamental to a language has been explored in many ways. However, many of these approaches place little emphasis on how humans learn, represent, and process language from a psychological perspective. In this study, we define and compare three distinct psycholinguistic measures of core vocabulary—word frequency, age‐of‐acquisition, and centrality in semantic networks—and test how well these core w…
Changing your mind about the data
When people use samples of evidence to make inferences, they consider both the sample contents and how the sample was generated ("sampling assumptions"). The current studies examined whether people can update their sampling assumptions - whether they can revise a belief about sample generation that is discovered to be incorrect, and reinterpret old data in light of the new belief. We used a property induction task where learners saw a sample of i…
Trans-inclusive gender categories are cognitively natural
Ambiguity attitudes in qualitative contexts
Most studies of ambiguity aversion rely on experimental paradigms involving monetary bets. Thus, the extent to which ambiguity aversion occurs outside of such contexts is much less understood, particularly when the situation cannot easily be reduced to numerical terms. The present work seeks to understand whether people prefer to avoid ambiguous decisions in a variety of different qualitative domains (e.g., work, family, love, friendship, exercis…

Saycam
We introduce a new resource: the SAYCam corpus. Infants aged 6–32 months wore a head-mounted camera for approximately 2 hr per week, over the course of approximately two-and-a-half years. The result is a large, naturalistic, longitudinal dataset of infant- and child-perspective videos. Over 200,000 words of naturalistic speech have already been transcribed. Similarly, the dataset is searchable using a number of criteria (e.g., age of participant,…
Social meta-inference and the evidentiary value of consensus
Reasoning beyond available data is a ubiquitous feature of humancognition. But while the availability of first-hand data typically diminishesas the concepts we reason about become more complex, our ability to drawinferences seems not to. We may offset the sparsity of direct evidence byobserving the statements of others, but such social meta-inference comes withchallenges of its own. The strength of socially-provided evidence depends onmultiple fa…
Culture and global societal threats
The COVID-19 global pandemic has brought into sharp focus the urgency of tackling the question of how globalized humanity responds to a global societal threat, which can adversely affect a large portion of the human population. Changing geospatial distribution of COVID-19 morbidity paints a gloomy picture of cross-national differences in human vulnerabilities across the globe. We describe the dynamic nexus among societal – particularly pathogen –…
The “Small World of Words” English word association norms for over 12,000 cue words
Word associations have been used widely in psychology, but the validity of their application strongly depends on the number of cues included in the study and the extent to which they probe all associations known by an individual. In this work, we address both issues by introducing a new English word association dataset. We describe the collection of word associations for over 12,000 cue words, currently the largest such English-language resource …
Even arbitrary norms influence moral decision-making
Piaget, Probability, Causality, and Contradiction
Bayesian Models of Cognition
This article explores some of the philosophical implications of the Bayesian modeling paradigm. In particular, it focuses on the ramifications of the fact that Bayesian models pre-specify an inbuilt hypothesis space. To what extent does this pre-specification correspond to simply ''building the solution in''? I argue that any learner (whether computer or human) must have a built-in hypothesis space in precisely the same sense that Bayesian models…
Probabilistic models of cognition
Variability, negative evidence, and the acquisition of verb argument constructions
We present a hierarchical Bayesian framework for modeling the acquisition of verb argument constructions. It embodies a domain-general approach to learning higher-level knowledge in the form of inductive constraints (or overhypotheses), and has been used to explain other aspects of language development such as the shape bias in learning object names. Here, we demonstrate that the same model captures several phenomena in the acquisition of verb co…
Picking up speed in understanding
To explore how online speech processing efficiency relates to vocabulary growth in the 2nd year, the authors longitudinally observed 59 English-learning children at 15, 18, 21, and 25 months as they looked at pictures while listening to speech naming one of the pictures. The time course of eye movements in response to speech revealed significant increases in the efficiency of comprehension over this period. Further, speed and accuracy in spoken w…
