A Computational Account of Complex Mental Image Construction
نویسنده
چکیده
This paper presents a computational cognitive model of the construction process of complex, i.e., multi-part, visual mental images. The model is integrated into the cognitive architecture Casimir. The construction process is realized by the interplay of a spatial working memory structure and a passive quasi-pictorial visual representation. Both structures are successively build up on demand from long-term memory. The correct placement of new parts is guided by the inspection of the visual representation. The model has two main advantages: 1) it is an explicitly cognitive computational model that implements the two-fold structure of a spatial and a visual working memory representation and 2) it introduces an attention window structure in such a way that allows for direct predictions of eye movements during mental imagery processes. We discuss predictions and explanations offered by model.

متن کاملA Computational Account of Complex Moral Judgement
In this paper, we analyze the task of complex moral judgement from a computational perspective. We present a theoretical framework that posits this process often involves the construction of a coherent explanation for observed behavior in terms of the mental states of the agents involved. We extend the framework to incorporate moral values as numeric annotations on cognitive structures and miti...
متن کاملGrayscale and Color Image Segmentation using Computational Topology
In this paper, we present image segmentation algorithms based on tools from computational algebraic topology and Morse theory. We build our implementations on a very general clustering algorithm [4], developed by Chazal et al., which has been adapted for both grayscale and color image segmentation. By building up a simplicial complex incrementally filtering its simplices by values of a scalar f...
