    Animal Foraging and the Evolution of Goal‐Directed Cognition.Thomas T. Hills - 2006 - Cognitive Science 30 (1):3-41.
    Foraging‐ and feeding‐related behaviors across eumetazoans share similar molecular mechanisms, suggesting the early evolution of an optimal foraging behavior called area‐restricted search (ARS), involving mechanisms of dopamine and glutamate in the modulation of behavioral focus. Similar mechanisms in the vertebrate basal ganglia control motor behavior and cognition and reveal an evolutionary progression toward increasing internal connections between prefrontal cortex and striatum in moving from amphibian to primate. The basal ganglia in higher vertebrates show the ability to transfer dopaminergic activity from (...)

    Foraging in Semantic Fields: How We Search Through Memory.Thomas T. Hills, Peter M. Todd & Michael N. Jones - 2015 - Topics in Cognitive Science 7 (3):513-534.
    When searching for concepts in memory—as in the verbal fluency task of naming all the animals one can think of—people appear to explore internal mental representations in much the same way that animals forage in physical space: searching locally within patches of information before transitioning globally between patches. However, the definition of the patches being searched in mental space is not well specified. Do we search by activating explicit predefined categories and recall items from within that category, or do we (...)

    (1 other version)Feature Biases in Early Word Learning: Network Distinctiveness Predicts Age of Acquisition.Tomas Engelthaler & Thomas T. Hills - 2016 - Cognitive Science 40 (6):n/a-n/a.
    Do properties of a word's features influence the order of its acquisition in early word learning? Combining the principles of mutual exclusivity and shape bias, the present work takes a network analysis approach to understanding how feature distinctiveness predicts the order of early word learning. Distance networks were built from nouns with edge lengths computed using various distance measures. Feature distinctiveness was computed as a distance measure, showing how far an object in a network is from other objects based on (...)

    Simple Threshold Rules Solve Explore/Exploit Trade‐offs in a Resource Accumulation Search Task.Ke Sang, Peter M. Todd, Robert L. Goldstone & Thomas T. Hills - 2020 - Cognitive Science 44 (2):e12817.
    How, and how well, do people switch between exploration and exploitation to search for and accumulate resources? We study the decision processes underlying such exploration/exploitation trade‐offs using a novel card selection task that captures the common situation of searching among multiple resources (e.g., jobs) that can be exploited without depleting. With experience, participants learn to switch appropriately between exploration and exploitation and approach optimal performance. We model participants' behavior on this task with random, threshold, and sampling strategies, and find that (...)

  13. The Evolutionary Origins of Cognitive Control.Thomas T. Hills - 2011 - Topics in Cognitive Science 3 (2):231-237.
    The question of domain-specific versus domain-general processing is an ongoing source of inquiry surrounding cognitive control. Using a comparative evolutionary approach, Stout (2010) proposed two components of cognitive control: coordinating hierarchical action plans and social cognition. This article reports additional molecular and experimental evidence supporting a domain-general attentional process coordinating hierarchical action plans, with the earliest such control processing originating in the capacity of dynamic foraging behaviors—predating the vertebrate-invertebrate divergence (c. 700 million years ago). Further discussion addresses evidence required for (...)

    Behavioral Network Science: Language, Mind, and Society.Thomas T. Hills - 2024 - Cambridge University Press.
    Behavioural Network Science provides a comprehensive introduction to network science for social and behavioral researchers and students. It is a self-contained guide to the fundamentals of network science, beginning with principles of representing and making networks, network metrics, and network evolution. It then delves into specific applications of network science to behavioral research including language evolution, learning, memory, aging, creativity, conspiracies, group problem-solving, opinion polarization, and social conflict. Within each application, theoretical aspects surrounding a core problem are discussed, providing readers (...)

  18. Age‐Related Diversification and Specialization in the Mental Lexicon: Comparing Aggregate and Individual‐Level Network Approaches.Dasol Jeong & Thomas T. Hills - 2024 - Cognitive Science 48 (11):e70008.
    The mental lexicon changes across the lifespan. Prior work, aggregating data among individuals of similar ages, found that the aging lexicon, represented as a network of free associations, becomes more sparse with age: degree and clustering coefficient decrease and average shortest path length increases. However, because this work is based on aggregated data, it remains to be seen whether or not individuals show a similar pattern of age-related lexical change. Here, we demonstrate how an individual-level approach can be used to (...)
