Pronunciation-by-analogy (PbA) is an emerging technique for text-phoneme conversion based on a psychological model of reading aloud. This paper explores the impact of certain basic implementational choices on the performance of various PbA models. These have been tested on their ability to pronounce sets of short pseudowords previously used in similar studies, as well as lexical words temporari...

Cognitive modeling is a complex endeavor so it is not surprising that the goals and intentions of modelers are often misunderstood, even by other modelers. To try to clarify this we have attempted to map out the various philosophical and theoretical commitments that one makes when creating a cognitive model or architecture. The goal of this is to avoid misunderstandings between the adherents of...

The article advances a hypothetic-and-cognitive model of holophrastic constructions’ decoding by the recipient’s consciousness as well as describes their speech generating function based on cognitive and probabilistic processes running under the control of individual’s consciousness

In common applications, a robot will have no prior knowledge of its environment and must use sensory information to build a cognitive model for path and route finding. The process of building a good cognitive model from sensory information alone is complex and time consuming. Uncertainty of the input data can also cause the resulting paths and routes to be suboptimal or erroneous. In many of th...

The procedure by which humans identify checks in check positions is not well understood. We report here our experience in modelling this process with CHREST, a general-purpose cognitive model that has previously successfully captured a variety of attentionand perception-related phenomena. We have attempted to reproduce the results of an experiment investigating the ability of humans to determin...

This paper describes our experience in the design and implementation of a web–based computer system to support employee selection or assessment. Instead of traditional questionnaires the test is a Role Playing Game session, to reduce repetitiveness and predictability, and therefore to increase its effectiveness. The story is dynamically built by a multi–agent system, that chooses between availa...

ion and Generalization of 3D structure for recognition in large intra-class variation Gowri Somanath and Chandra Kambhamettu Video/Image Modeling and Synthesis (VIMS) Lab, Department of Computer and Information Sciences, University of Delaware, Newark, DE, USA. http://vims.cis.udel.edu Abstract. Humans have abstract models for object classes which helps recognize previously unseen instances, de...

On the basis of findings from an experiment with 6-year-old children we show a proposal for a cognitive model of representational shifts in learning the number line. The findings from the experiment provide information on number line estimation that is, translating a number to a spatial position on a number line. Though the experiment is a replication of an experiment done by Siegler and Ramani...

A first step is taken towards incorporating emotional processing into Sigma, a cognitive architecture that is grounded in graphical models, with the addition of appraisal variables for expectedness and desirability plus their initial implications for attention at two levels of the control hierarchy. The results leverage many of Sigma’s existing capabilities but with a few key additions.
