Neuropsychology and Explainability of AI: A Distributional Approach to the Relationship Between Activation Similarity of Neural Categories in Synthetic Cognition

Within an explainability framework, the neuropsychology of artificial intelligence focuses on studying synthetic neural cognitive mechanisms, considering them as new subjects of cognitive psychology research. The goal is to make artificial neural networks used in language models understandable by adapting concepts from human cognitive psychology to the interpretation of artificial neural cognition. In this context, the notion of categorization is particularly relevant because it plays a key role as a process of segmentation and reconstruction of informational data by the neural vectors of synthetic cognition. Thus, in this study, the aim is to use the concept of categorization, as understood in human cognitive psychology (particularly in its relation to the notion of similarity), to apply it to the analysis of neural behavior and to infer certain synthetic cognitive processes underlying the observed behaviors.
