Over the last decade, cognitive science and allied fields have been criticized for being excessively “WEIRD,” i.e., overly reliant on participants from Western, Educated, Industrialized, Rich, and Democratic societies. The lack of diversity among research participants is now widely acknowledged, but it’s a rather superficial problem, symptomatic of other more fundamental ones. This poster outlines what we see as four overlapping problems. Cognitive science is WEIRD not only in terms of who makes up its participant pool, but also in terms of its theoretical commitments (e.g., individualism and universalism), methodological assumptions (e.g., measurement and analysis methods), and institutional structures (e.g., funding and publishing). Merely solving the problem of WEIRD participants by sampling more widely is insufficient to address cognitive science’s more fundamental WEIRD theoretical, methodological and institutional problems. Coming to terms with this is necessary if we wish to make cognitive science relevant for all humanity.

The 45th Annual Meeting of the Cognitive Science Society presents the latest research across cognitive science and highlights the theme of Cognition in Context.

Recent studies and models have been successful in describing human search in choice-rich environments in terms of different generalization and exploration strategies. However, it remains an open question how and to what extent people adapt these strategies to different environments. Therefore, we used a within-subject manipulation to study human search in two classes of environments, where the reward distributions differed in the strength of spatial correlations. These environments were chosen through simulations designed to maximize the need for deploying different generalization strategies. We describe participant behavior with the parameters of a model using Gaussian Process function learning to generalize and an Upper Confidence Bound to sample from unexplored options. Our results show that while participants adapted their exploration strategies, their generalization remained unchanged across environments. Together, these findings offer important first insights into how people adapt decision-making strategies depending on environmental demands in vast decision spaces.

Environment-sensitive generalization and exploration strategies

There has been a recent surge of interest in how people assign
subjective value to outcomes that are both risky and delayed,
referred to as risky intertemporal gambles. In most studies,
subjective value has been determined through preferences between
binary choices, yet subjective value and preference can
be determined by willingness-to-pay values or other prices
assigned to each prospect. The present study aims to compare
factors that influence the subjective value of risky intertemporal
prospects between a choice task and a pricing
task. Preferences during choice and pricing were assessed
when outcomes were beneficial (gains) or harmful (losses).
Cognitive models of each task quantify both common parameters
that influence subjective value and specific parameters
involved in each response process. Results suggest that differences
extend beyond simple differences in elicitation procedure:
during pricing, people paid greater attention to payoffs
while exhibiting greater self-control and risk aversion compared
to choice.

Inattentional blindness, the failure to detect obvious and 
unexpected events when attention is elsewhere, is consistently 
underestimated. Instead, people overestimate the ability to 
notice unexpected events in hindsight. No studies have yet 
determined whether beliefs about the noticing of unexpected 
events differ depending on whose visual experience is being 
evaluated. In the current experiment, one-hundred and fortyeight participants read four vignettes depicting legally-relevant 
scenarios. Half of participants imagined that they were the 
individual in the scenario, while the other half imagined that 
the individual was someone else. Participants rated the 
likelihood of noticing each unexpected event and their 
confidence in their judgment. Perspective did not affect 
likelihood ratings or confidence in isolation, but the effect of 
perspective on likelihood judgments did depend on the 
scenario. Additionally, there were differences in likelihood 
judgments and confidence based on scenario, with participants 
believing an event would be more likely to be noticed in more 
relatable legal scenarios (e.g., witness and driving) compared 
to highly specialized scenarios (e.g., CCTV and medicine). 
Thus, visual metacognitive judgments do not appear to 
reliability differ based on the individual being evaluated; 
instead, features of the scenario may be more important.

Does visual metacognition differ based on perspective?

While people report a multitude of factors that determine their food choices (Marcone et al., 2020), laboratory studies often focus on taste and health over other attributes, such as price and convenience, which are often considered irrelevant. In two studies, we found that convenience, a previously overlooked attribute, impacts lab-based food choice. Study 1 (N=118) used a thought-listing paradigm, identifying convenience (22.7%) as a frequently-considered thought during food choice, after taste (43.7%) and health (32.8%). Importantly, in study 2 (N = 94) we found that convenience (β=0.06, p<.001) predicted lab-based food choice, even after controlling for taste (β=0.40, p<.001) and health (β=0.08, p<.001). However, revealed food preferences from lab-based choices were not associated with self-reported preferences from questionnaires, suggesting that integrating more real-world considerations is needed to bridge between laboratory and naturalistic food choices.

Real-world convenience shapes laboratory food choices even when irrelevant

Fermi problems are often taught in science and engineering as a technique for difficult numerical estimation in which a question is broken down into sub-questions that people can more confidently estimate. Thus, they may be tools providing insight into how people estimate numbers. However, there are no empirical studies into the effectiveness of Fermi problems. This study presented participants with the same questions as both Fermi problems (with sub-questions) and as non-Fermi problems (no sub-questions) and tested the hypothesis that participants’ estimates would be more accurate when presented with Fermi problems than non-Fermi problems. The same data tested a hypothesis that participants would better fit to Benford’s law when presented with Fermi problems than non-Fermi problems. Neither hypothesis was supported, although the strong fit of peoples estimates to Benford’s law was replicated. This first attempt to empirically examine Fermi problems pointed to ways to more rigorously test these hypotheses.

Fermi problems as tools for understanding number generation and Benford’s law

We propose a method to use anchor-biased numerical estimates to enhance the wisdom of the crowd (i.e., aggregating individual estimates becomes more accurate). We predicted that better wisdom of crowds could be achieved by combining estimates affected by two sufficiently different anchors. This prediction was based on the hypothesis that anchoring effects could be used to collect estimates from diverse perspectives, and better crowd wisdom could be achieved by aggregating anchor-biased estimates. To test this hypothesis, we conducted a behavioral experiment on anchoring effects and computer simulations of the wisdom of crowds. The behavioral experiment revealed that anchor-biased estimates did not always produce larger errors but produced more accurate or less accurate estimates depending on the relationship between the anchor and true values. We also found that even in the absence of anchoring effects, the estimates were biased. Thus, estimates without anchor bias were not always more accurate than anchor-biased estimates. The results of computer simulations revealed that robust and better wisdom of crowds could be achieved using the proposed method. Contrastingly, aggregating estimates that were not biased by anchors did not always lead to better wisdom of crowds.

Effective utilization of anchor-biased estimates for the wisdom of crowds

Existing studies of the serial reproduction paradigm focused on stimuli that were statistically independent of each other. We explored serial reproductions of random walk series and examined whether Bayesian models previously built for independent stimuli could be adapted to autocorrelated stimuli. We found that Bayesian models captured most of the empirical results qualitatively, but could be further improved by incorporating recency effects. Besides, given that the optimal strategy of iterative prediction of random walk was to reproduce the current stimuli, we also compared serial prediction of random walk to serial reproduction. We found that serially reproduced and predicted series both decorrelate as a function of chain position and that the means of the series increase in both tasks, which matched qualitative predictions of the Bayesian models.

Comparing serial reproduction and serial prediction of random walk

Confidence is an important concept in cognitive science, as it integrates seamlessly with our beliefs, goals, and decisions. However, the dynamics of how beliefs about hypotheses (represented by a Bayesian posterior probability distribution) give rise to explicitly reported confidence judgments about predictions (which are typically measured on various numerical scales) in the human mind is not well understood. In this work, we report findings on this question from a concept learning and confidence judgment experiment. We compare how leading theories in the present literature stands against our data and propose some new model-based measurements and future directions for predicting humans' confidence judgments.

Towards a model of confidence judgements

During class, taking notes helps the encoding process, especially when students reformulate what is presented. After class, notes can be used for revision. Previous studies, mostly conducted in laboratory contexts, showed that note-taking on paper seems to be more efficient than on computer, probably because students are more likely to reformulate on paper. The originality of this study is to investigate students’ perceptions and strategies depending on their note-taking method during but also after class. Data of 108 students showed that students on paper (30%) declare making more reformulations and less multitasking that students on computer (70%). After class, review sheets are written for a large majority of the students on paper, whatever the method they used during class. These results suggest that even if computer is the most used method during class, paper is still used after class, and with paper are associated better strategies.

Note-taking during and after class: which strategies for which method?

Science teaching is a complex socio-cognitive practice, where teachers simultaneously collaborate with and influence student minds. This process is distributed across textbooks, explanations, blackboard activities, classroom dynamics, student questions, student performance, etc.; and enactive, as teachers act out scientific mechanisms using descriptions, gestures, teaching props, models etc. This complex process of Teacher Cognition (TC) is not well understood, as existing studies are disparate, and based on disjointed approaches. The lack of a TC theory limits the design of systematic education policies - currently based on intuitions about teacher cognition - leading to policy guidelines that teachers find difficult to implement. Recent developments in embodied/enactive cognition theory – particularly the enactive simulation model of language and the enactive simulation theory of other minds – provide useful ways to develop models of TC, especially related to science teaching. Here we extend and develop a finer-grained version of a recent enactive model of TC, using classroom data.
