This work aims to expand the computational theory of early cognitive mapping proposed by Yeap (1988) and Yeap and Jefferies (1999). Yeap and Jefferies developed a computational theory based on human cognitive mapping studies. Their theory starts from a 2 1/2-D sketch that is the output of Marr's vision theory (Marr, 1982). They attempt to answer the question of what is computed first from 2 1/2-D sketch. They argue that the boundary of the local space which one is surrounded by is computed first. Yeap and Jefferies' theory and implementations are limited with early cognitive mapping excluding landmark mknowledge. This work aims to improve the theory by integrating landmark infor mation into early cognitive mapping. Landmarks are used for encoding spatial relations within local spaces. A local matching method by using landmarks is proposed for recognition of revisited local spaces. Acquisition of more detailed metric information within local spaces by using landmarks and improved ability in the recognition of revisited local spaces are also among the main improvements obtained by integrating landmarks into Yeap and Jefferies' cognitive maps.

Structure and process: prospects for theories of cognitive science Özkan, Ayşegül; Sayan, Erdinç; Department of Philosophy (2010) Different theories of cognitive science propose different system descriptions in their models for the explanation of cognitive phenomena. According to one view, they are incompatible and competing theories. The view is defended by theorists and philosophers from different perspectives and they all claim that the proper conception of cognition is the conception provided by the theory which they advocate. The other view, on the other hand, insists on the compatibility of those theories. According to this view...
Inflating the social aspects of cognitive structural realism Davoody Benı, Majıd (2021-09-01) Inspired by Ronald Giere's (1989, 1992) cognitive approach to scientific models, Cognitive Structural Realism (CSR) has presented a naturalist account of scientific representation (Beni, 2019a). CSR characterises the structure of theories in terms of cognitive structures. These are informational structures embodied in the brains of (allegedly individual) scientists. CSR accounts for scientific representation in terms of the dynamical relationship between the organism and its environment. The proposal has be...
A philosophical analysis of computational modeling in cognitive science Ürgen, Burcu Ayşen; Bağçe, Samet; Department of Cognitive Sciences (2007) This study analyses the methodology of computational cognitive modeling as one of the ways of conducting research in cognitive science. The aim of the study is to provide an understanding of the place of computational cognitive models in understanding human cognition. Considering the vast number of computational cognitive models which have been just given to account for some cognitive phenomenon by solely simulating some experimental study and fitting to empirical data, a practice-oriented approach is adopt...
An extended tube model for thermo viscoelasticity of rubberlike materials Theory and numerical implementation Behnke, Ronny; Dal, Hüsnü; Kaliske, Michael (2011-09-23) This contribution is devoted to the further development of the original purely hyperelastic extended tube model, presented by Kaliske & Heinrich (1999), to finite nonlinear thermo-viscoelasticity using a nonlinear evolution law and a thermo-mechanical coupled free energy formulation. Particular emphasis is given to an appropriate parameter identification technique for the thermal field. For the latter, a uniaxial extension test is carried out where the recorded data of the temperature field of the rubber sp...
Cognitive aspects of conceptual modeling diagrams : an experimental study Kılıç, Özkan; Say, Bilge; Department of Cognitive Sciences (2007) This thesis is about diagrammatic reasoning and error-finding in conceptual modeling diagrams. Specifically, the differences of the cognitive strategies and behaviors of notation-familiar participants versus domain-familiar participants working on conceptual modeling diagrams are inspected. The domain-familiar participants are experienced in the topic being represented, but they do not have any formal training in software development representations. On the other hand, the notation-familiar participants are...
