  • An Agent‐Based Model of Semantic Memory Search

    Open AccessDiego Morales, D Job Morales et al.ARTICLECognitive Science2025References: 62

    Verbal fluency tasks reveal clustering and switching patterns traditionally explained by strategic search or stochastic processes like Lévy or random walks. However, previous comparisons ignored how search processes interact with semantic structure, leaving unclear whether model performance reflects strategic mechanisms or fortuitous alignment with semantic organization. This study developed and validated a novel Area Restricted Search (ARS) agen…

  • A mathematical model of semantic access in lexical and semantic decisions

    Open AccessSergio E Chaigneau, Nicolás Marchant et al.ARTICLELanguage and Cognition2024

    In this work, we use a mathematical model of the property listing task dynamics and test its ability to predict processing time in semantic and lexical decision tasks. The study aims at exploring the temporal dynamics of semantic access in these tasks and showing that the mathematical model captures essential aspects of semantic access, beyond the original task for which it was developed. In two studies using the semantic and lexical decision tas…

  • Mechanisms Behind Public School Enrollment Trends in School Choice Systems

    Open AccessCatalina Canals, Marouli et al.ARTICLEJournal of Artificial Societies…2024

    Market-based reforms in education have expanded worldwide, often raising questions about their impact on the strength and sustainability of the public education sector.In this paper, we explore how such "school choice" policies affected public school enrollment in Chile, a country where a nationwide school choice reform coincided with a decline in public enrollment.To better understand the factors driving the public enrollment decline, we develop…

  • Mechanisms Underlying Choice-Set Formation

    Open AccessCatalina Canals, Marouli et al.ARTICLESocial Science Computer Review2022Cited by: 2References: 9

    Many decisions involve selecting among many more options than an individual can effectively examine and consider. Therefore, people usually consider smaller and different “choice sets” as viable options. To better understand the processes affecting choice-set formation, we developed a computational model of how households become aware of potential choices in a context for which understanding household decision-making has important public policy i…

  • Modeling stereotypes and negative self‐stereotypes as a function of interactions among groups with power asymmetries

    Open AccessRodrigo Lagos, Enrique Canessa et al.ARTICLEJournal for the Theory of Social…2019References: 76

    Stereotypes is one of the most researched topics in social psychology. Within this context, negative self‐stereotypes pose a particular challenge for theories. In the current work, we propose a model that suggests that negative self‐stereotypes can theoretically be accounted for by the need to communicate in a social system made up by groups with unequal power. Because our theory is dynamic, probabilistic, and interactionist, we use a computation…
