    Building Cognition: The Construction of Computational Representations for Scientific Discovery.Sanjay Chandrasekharan & Nancy J. Nersessian - 2015 - Cognitive Science 39 (8):1727-1763.
    Novel computational representations, such as simulation models of complex systems and video games for scientific discovery, are dramatically changing the way discoveries emerge in science and engineering. The cognitive roles played by such computational representations in discovery are not well understood. We present a theoretical analysis of the cognitive roles such representations play, based on an ethnographic study of the building of computational models in a systems biology laboratory. Specifically, we focus on a case of model-building by an engineer that (...)

    Building to Discover: A Common Coding Model.Sanjay Chandrasekharan - 2009 - Cognitive Science 33 (6):1059-1086.
    I present a case study of scientific discovery, where building two functional and behavioral approximations of neurons, one physical and the other computational, led to conceptual and implementation breakthroughs in a neural engineering laboratory. Such building of external systems that mimic target phenomena, and the use of these external systems to generate novel concepts and control structures, is a standard strategy in the new engineering sciences. I develop a model of the cognitive mechanism that connects such built external systems with (...)

    Recombinant Enaction: Manipulatives Generate New Procedures in the Imagination, by Extending and Recombining Action Spaces.Jeenath Rahaman, Harshit Agrawal, Nisheeth Srivastava & Sanjay Chandrasekharan - 2018 - Cognitive Science 42 (2):370-415.
    Manipulation of physical models such as tangrams and tiles is a popular approach to teaching early mathematics concepts. This pedagogical approach is extended by new computational media, where mathematical entities such as equations and vectors can be virtually manipulated. The cognitive and neural mechanisms supporting such manipulation-based learning—particularly how actions generate new internal structures that support problem-solving—are not understood. We develop a model of the way manipulations generate internal traces embedding actions, and how these action-traces recombine during problem-solving. This model (...)

    Rethinking correspondence: how the process of constructing models leads to discoveries and transfer in the bioengineering sciences.Nancy J. Nersessian & Sanjay Chandrasekharan - 2017 - Synthese 198 (Suppl 21):1-30.
    Building computational models of engineered exemplars, or prototypes, is a common practice in the bioengineering sciences. Computational models in this domain are often built in a patchwork fashion, drawing on data and bits of theory from many different domains, and in tandem with actual physical models, as the key objective is to engineer these prototypes of natural phenomena. Interestingly, such patchy model building, often combined with visualizations, whose format is open to a wide range of choice, leads to the discovery (...)

    Sum, quorum, tether: Design principles underlying external representations that promote sustainability.Sanjay Chandrasekharan & Mark Tovey - 2012 - Pragmatics and Cognition 20 (3):447-482.
    We outline three challenges involved in designing external representations that promote sustainable use of natural resources. First, the task environment of sustainable resource-use is highly unstructured, and involves many uncoordinated and asynchronous actions. Following from this complex nature of the task environment, more task constraints and task interactions are involved in designing representations promoting sustainability, compared to representations that seek to make tasks easier in structured task environments, such as aircraft cockpits and control rooms. Second, external representations promoting sustainable resource-use (...)

    Beyond Telling: Where New Computational Media is Taking Model-Based Reasoning.Sanjay Chandrasekharan - 2006 - In Lorenzo Magnani & Claudia Casadio (eds.), Model Based Reasoning in Science and Technology. Logical, Epistemological, and Cognitive Issues. Cham, Switzerland: Springer International Publishing.
    The emergence of new computational media is radically changing the practices of science, particularly in the way computational models are built and used to understand and engineer complex biological systems. These new practices present a novel variation of model-based reasoning, based on dynamic and opaque models. A new cognitive account of MBR is needed to understand the nature of this practice and its implications. To develop such an account, I first outline two cases where the building and use of computational (...)

    Counterfactuals in science and engineering.Sanjay Chandrasekharan & Nancy J. Nersessian - 2007 - Behavioral and Brain Sciences 30 (5-6):454-455.
    The notion of mutation is applicable to the generation of novel designs and solutions in engineering and science. This suggests that engineers and scientists have to work against the biases identified in counterfactual thinking. Therefore, imagination appears a lot less rational than claimed in the target article.

    Ideomotor design.Sanjay Chandrasekharan, Alexandra Mazalek, Michael Nitsche, Yanfeng Chen & Apara Ranjan - 2010 - Pragmatics and Cognition 18 (2):313-339.
    Recent experiments show video games have a range of positive cognitive effects, such as improvement in attention, spatial cognition and mental rotation, and also overcoming of cognitive disabilities such as fear of flying. Further, game environments are now being used to generate scientific discoveries, and bring about novel phenomenological effects, such as out-of-body experiences. These advances provide interesting interaction design possibilities for video games. However, since the cognitive mechanisms underlying these experimental effects are unknown, it is difficult to systematically derive (...)

    Money as epistemic structure.Sanjay Chandrasekharan - 2006 - Behavioral and Brain Sciences 29 (2):183-184.
    A testable model of the origin of money is outlined. Based on the notion of epistemic structures, the account integrates the tool and drug views using a common underlying model, and addresses the two puzzles presented by Lea & Webley (L&W) – money's biological roots and the adaptive significance of our tendency to acquire money.

    Solving for Pattern: An Ecological Approach to Reshape the Human Building Instinct.Geetanjali Date, Deborah Dutta & Sanjay Chandrasekharan - 2021 - Environmental Values 30 (1):65-92.
    The human species' adaptive advantage is driven by its ability to build new material structures and artefacts. Engineering is the modern manifestation of this building instinct, and its advent has made the construction and use of technologies the central pattern of human life. In parallel, efficiency, the overarching narrative driving technology and related life practices, has pervaded most occupations as a value, forming a cultural backdrop that implicitly guides decisions and behaviour. We examine the process through which this backdrop has (...)
