Humans, including preschool children, exhibit role-based relational reasoning, of which analogical reasoning is a canonical example. The "role-less" connectionist model proposed in the target article is only capable of conditional paired-associate learning. [ABSTRACT FROM AUTHOR]

Deals with the role of localist mental representations as the starting point for connectionist representations of symbolic or relational structures. Significance of localist nodes for the representation of relational structures; Notion of a localist representation.

Explores the meaning and implications of the study undertaken by Schyns et al on categorization and perceptual learning. Categorization experience created by visual features governing object classifications; Necessity of clearer understanding about nonderivability; Interpretations of nonderivability.

van der Velde & de Kamps argue for the importance of considering the binding problem in accounts of human mental representation. However, their proposed solution fails as a complete account because it represents the bindings between roles and their fillers through associations (or connections). In addition, many criticisms leveled by the authors towards synchrony-based bindings models do not hold. [ABSTRACT FROM AUTHOR]

We are big fans of propositions. But we are not big fans of the "propositional approach" proposed by Mitchell et al. The authors ignore the critical role played by implicit, non-inferential processes in biological cognition, overestimate the work that propositions alone can do, and gloss over substantial differences in how different kinds of animals and different kinds of cognitive processes approximate propositional representations.
