Packing: A Geometric Analysis of Feature Selection and Category Formation.

Cogn Syst Res 2011 Mar;12(1):1-18

Department of Psychological and Brain Sciences, Indiana University.

This paper presents a geometrical analysis of how local interactions in a large population of categories packed into a feature space create a global structure of feature relevance. The theory is a formal proof that the joint optimization of discrimination and inclusion creates a smooth space of categories such that near categories in the similarity space have similar generalization gradients. Packing theory offers a unified account of several phenomena in human categorization including the differential importance of different features for different kinds of categories, the dissociation between judgments of similarity and judgments of category membership, and children's ability to generalize a category from very few examples.

On Strong Anticipation.

Authors:
N Stepp M T Turvey

Cogn Syst Res 2010 Jun;11(2):148-164

University of Connecticut, 406 Babbidge Rd, U-1020, Storrs, CT 06269-1020.

We examine Dubois's (2003) distinction between weak anticipation and strong anticipation. Anticipation is weak if it arises from a model of the system via internal simulations. Anticipation is strong if it arises from the system itself via lawful regularities embedded in the system's ordinary mode of functioning. Read More

Fragile X syndrome: Neural network models of sequencing and memory.

Cogn Syst Res 2008 Oct;9(4):274-292

Arizona State University, Tempe and The NeuronFarm.

A comparative framework of memory processes in males with fragile X syndrome (FXS) and Typically Developing (TYP) mental age-match children is presented. Results indicate a divergence in sequencing skills, such that males with FXS recall sequences similarly to TYP children around five and a half years of age, but eth males with FXS recall significantly worse when compared to TYP children around seven and a half years of age. Performance on one working memory measure, an n-back card task, is modeled with a neural network. Read More

AFFECTIVE GUIDANCE OF INTELLIGENT AGENTS: How Emotion Controls Cognition.

Cogn Syst Res 2009 Mar;10(1):21-30

Department of Psychology University of Virginia.

Emotions and moods color cognition. In this article, we outline how emotions affect judgments and cognitive performance of human agents. We argue that affective influences are due, not to the affective reactions themselves, but to the information they carry about value, a potentially useful finding for creators of artificial agents.
