Disentangling Perceptual and Process-Related Sources of Behavioral Variability in Categorization
People often categorize the same object variably over time. Such intraindividual behavioral variability is difficult to identify because it can be confused with a bias and can originate in different categorization steps. The current work discusses possible sources of behavioral variability in categorization, focusing on perceptual and cognitive processes, and reports a simulation with a similarity-based categorization model to disentangle these s…
Identifying similarity- and rule-based processes in quantitative judgments
Quantitative judgments have been suggested to result from a mixture of similarity- and rule-based processing. People can judge an object’s criterion value based on the object’s similarity to previously experienced exemplars and based on a rule that integrates the object’s cues like a linear regression. In order to better understand these processes, the present work combines cognitive modeling and eye tracking and tests whether people who rely mor…
A robust Bayesian test for identifying context effects in multiattribute decision-making
Research on multiattribute decision-making has repeatedly shown that people’s preferences for options depend on the set of other options they are presented with, that is, the choice context. As a result, recent years have seen the development of a number of psychological theories explaining context effects. However, much less attention has been given to the statistical analyses of context effects. Traditionally, context effects are measured as a …
Testing three coping strategies for time pressure in categorizations and similarity judgments
This article compares three psychological mechanisms to make multi-attribute inferences under time pressure in the domains of categorization and similarity judgments. Specifically, we test if people under time pressure attend to fewer object features (attention focus), if they respond less precisely (lower choice sensitivity), or if they simplify a psychological similarity function (simplified similarity). The simpler psychological similarity con…
Cognitive abilities affect decision errors but not risk preferences
When making risky decisions, people should evaluate the consequences and the chances of the outcome occurring. We examine the risk-preference hypothesis , which states that people’s cognitive abilities affect their evaluation of choice options and consequently their risk-taking behavior. We compared the risk-preference hypothesis against a parsimonious error hypothesis , which states that lower cognitive abilities increase decision errors. Increa…
Risk preferences and risk perception affect the acceptance of digital contact tracing
Digital contact-tracing applications (DCTAs) can help control the spread of epidemics, such as the coronavirus disease 2019 pandemic. But people in Western societies fail to install DCTAs. Understanding the low use rate is key for policy makers who support DCTAs as a way to avoid harsh nationwide lockdowns. In a preregistered study in a representative German-speaking Swiss sample ( N = 757), the roles of individual risk perceptions, risk preferen…
The influence of visual attention on memory-based preferential choice
Distinguishing three effects of time pressure on risk taking
Quick decision making under risk is ubiquitous in modern times, yet its consequences are not fully understood. Time pressure might change people's risk preferences, lead to less consistent choices, or change people's decision strategy. With the present work, we make the novel contribution of testing all hypotheses against each other in a unifying hierarchical Bayesian model. In two studies, participants decided repeatedly between two risky gamble…
Reaching for the star ratings
Online consumer ratings provide information about the average evaluation but also about the number of people who provided a rating (i.e., the sample size) and thus the rating's reliability. Using aggregated data, previous research has provided mixed results with regards to whether people pay attention to the sample size of statistical information. In our experiment, people choose between two competing hotels based on previous visitors' ratings. F…
A sampling model of social judgment
Studies of social judgments have demonstrated a number of diverse phenomena that were so far difficult to explain within a single theoretical framework. Prominent examples are false consensus and false uniqueness, as well as self-enhancement and self-depreciation. Here we show that these seemingly complex phenomena can be a product of an interplay between basic cognitive processes and the structure of social and task environments. We propose and …
Risk preference shares the psychometric structure of major psychological traits
On the basis of 39 risk-taking measures, this study finds evidence for a general and stable factor of risk preference.
On Narrow Norms of Rationality and Questionable Data Analyses
In many areas of psychology, it has been argued that people are equipped with a repertoire of strategies to solve the problems they face. Past work has also shown that in situations in which people receive feedback about the correctness of their inferences, substantial learning effects occur, such that simple heuristics that perform well in an environment also do well in describing people's inferences (e.g., Rieskamp, 2006; Rieskamp & Otto, 2006)…
The risk elicitation puzzle
Probabilistic Inferences Under Emotional Stress
Many models of decision making neglect emotional states that could affect individuals' cognitive processes. The present work explores the effect of emotional stress on people's cognitive processes when making probabilistic inferences. Two contrasting hypotheses are tested against one another: the uncertainty‐reduction and attention‐narrowing hypotheses of how emotional stress affects decision making. In the experimental study, emotional stress wa…
Intuitive judgments of social statistics
SSL
The assumption that people possess a repertoire of strategies to solve the inference problems they face has been raised repeatedly. However, a computational model specifying how people select strategies from their repertoire is still lacking. The proposed strategy selection learning (SSL) theory predicts a strategy selection process on the basis of reinforcement learning. The theory assumes that individuals develop subjective expectations for the…
