Résumé
Some cognitive theories (e.g., Thagard and Stewart 2011, Eliasmith 2013) claim that various aspects of cognition can be explained by applying the operations underlying HRRs to modal representations. Doubts based on theoretical considerations have however been raised regarding the compatibility of HRR operations and modal representations (Fisher et al. 1987). This paper aims to provide a qualitative test for the claim that HRR operations can be used with modal representations. Our results are mostly positive, while not entirely settling the issue. All types of representations (whether randomly or modally generated) processed with HRR operations fare better in high dimensions as opposed to lower dimensions. However, while the performance of modal representations remains acceptable in high dimensions, there is a distinct degradation of performance with this type of representations. Moreover, the standardization process in such cases plays a greater role than it should considering its low neural plausibility.
