    Mechanisms of Reference Frame Selection in Spatial Term Use: Computational and Empirical Studies.Holger Schultheis & Laura A. Carlson - 2017 - Cognitive Science 41 (2):276-325.
    Previous studies have shown that multiple reference frames are available and compete for selection during the use of spatial terms such as “above.” However, the mechanisms that underlie the selection process are poorly understood. In the current paper we present two experiments and a comparison of three computational models of selection to shed further light on the nature of reference frame selection. The three models are drawn from different areas of human cognition, and we assess whether they may be applied (...)

  5. Casimir: An Architecture for Mental Spatial Knowledge Processing.Holger Schultheis & Thomas Barkowsky - 2011 - Topics in Cognitive Science 3 (4):778-795.
    Mental spatial knowledge processing often uses spatio-analogical or quasipictorial representation structures such as spatial mental models or mental images. The cognitive architecture Casimir is designed to provide a framework for computationally modeling human spatial knowledge processing relying on these kinds of representation formats. In this article, we present an overview of Casimir and its components. We briefly describe the long-term memory component and the interaction with external diagrammatic representations. Particular emphasis is placed on Casimir’s working memory and control mechanisms. Regarding (...)

    Action Selection in Everyday Activities: The Opportunistic Planning Model.Petra Wenzl & Holger Schultheis - 2024 - Cognitive Science 48 (4):e13444.
    While action selection strategies in well‐defined domains have received considerable attention, little is yet known about how people choose what to do next in ill‐defined tasks. In this contribution, we shed light on this issue by considering everyday tasks, which in many cases have a multitude of possible solutions (e.g., it does not matter in which order the items are brought to the table when setting a table) and are thus categorized as ill‐defined problems. Even if there are no hard (...)

    Modeling Mental Spatial Reasoning About Cardinal Directions.Holger Schultheis, Sven Bertel & Thomas Barkowsky - 2014 - Cognitive Science 38 (8):1521-1561.
    This article presents research into human mental spatial reasoning with orientation knowledge. In particular, we look at reasoning problems about cardinal directions that possess multiple valid solutions , at human preferences for some of these solutions, and at representational and procedural factors that lead to such preferences. The article presents, first, a discussion of existing, related conceptual and computational approaches; second, results of empirical research into the solution preferences that human reasoners actually have; and, third, a novel computational model that (...)

    A Smart Model of Imaginal Perspective Taking.Holger Schultheis - 2022 - Cognitive Science 46 (12):e13218.
    The ability to judge spatial relations from perspectives that differ from one's current body orientation and location is important for many everyday activities. Despite considerable research on imaginal perspective taking, however, detailed computational accounts of the processes involved in this ability are missing. In this contribution, I introduce Smart (Spatial Memory Access by Reference Frame SelecTion) as a computational cognitive model of imaginal perspective taking processes. In assuming that imaginal perspective taking is governed by reference frame selection for memory access (...)

    Just the tip of the iceberg: The bicoded map is but one instantiation of scalable spatial representation structures.Holger Schultheis & Thomas Barkowsky - 2013 - Behavioral and Brain Sciences 36 (5):565-566.
    Although the bicoded map constitutes an interesting candidate representation, proposing it as the predominant representation for three-dimensional space is too restrictive. We present and argue for scalable spatial representation structures as a more comprehensive alternative account that includes the bicoded map as a special case.

    Of mice and men: Revisiting the relation of nonhuman and human learning.Holger Schultheis & Harald Lachnit - 2009 - Behavioral and Brain Sciences 32 (2):224-225.
    To support their main claim, Mitchell et al. broach the issue of the relationship between the learning performance of human and nonhuman animals. We show that their argumentation is problematic both theoretically and empirically. In fact, results from learning studies with humans and honey-bees strongly suggest that human learning is not entirely propositional.
