%0 PDF %T Testing Analogical Transfer in Pigeons (Columba livia) and Humans (Homo sapiens) %A Qadri, Muhammad. %8 2017-04-18 %R http://localhost/files/pz50h7668 %X Abstract: Categorization allows organisms to behave appropriately to novelty. In a recent method, categorization has been investigated with stimuli that vary parametrically in their features. Previous research has found that primates can approach this task using rules, whereas pigeons only use associative processing. Furthermore, using these stimuli, analogical transfer has been demonstrated in primates by testing stimuli in a new region of the feature space after restricted training. However, the fundamental dimensionality of the task seems to generate such "analogical transfer," regardless of rule-based processing mechanisms. Here, seven pigeons were successfully trained and tested with that original task to determine whether they show effects of analogical transfer. The pigeons were then further tested to determine the generality of their solution to the discrimination task. To explain their results, an association-based model of the task is developed using neural networks with a stimulus representation that is configural or dimensional. A method was developed to determine the likelihood of this association-based responding and evaluated against the pigeons' data. Finally, comparable human data was collected and the performance was analyzed to determine whether human procedural learning conforms to this unbound, dimensional stimulus representation. The impact of this shift in fundamental representation on our understanding of human cognition and categorization behavior more broadly is discussed.; Thesis (Ph.D.)--Tufts University, 2017.; Submitted to the Dept. of Psychology.; Advisors: Robert Cook, and Matthias Scheutz.; Committee: Holly Taylor, and F.
