Theories that span tasks and developmental periods require explaining how a single cognitive system can flexibly adapt across contexts yet show stable age-related improvement. Here we present a computational model that embodies a unified theory of visuospatial cognitive development. We use this model to bridge between previously disconnected domains, as diverse as infant habituation and visual ...

This presentation proposes a new account of homology, which defines homology as a correspondence of developmental or behavioral mechanisms due to common ancestry. The idea is formally presented as isomorphism of causal graphs over lineages. The formal treatment not only clears the metaphysical skepticism regarding the homology thinking, but also provides a theoretical underpinning to the concep...

The development of reading skill and bases of developmental dyslexia were explored using connectionist models. Four issues were examined: the acquisition of phonological knowledge prior to reading, how this knowledge facilitates learning to read, phonological and nonphonological bases of dyslexia, and effects of literacy on phonological representation. Compared with simple feedforward networks,...

The aim of this paper is to provide a parsimonious account of developmental and individual differences in intelligence (measured as g). The paper proposes a Differential–Developmental Model (DDM), which focuses on factors common to intelligence and cognitive development (e.g., mental speed and attention lapses). It also proposes a complementary method based on Jensen’s box, a chronometric devic...

One might expect that children with varying genetic mutations or children raised in low socioeconomic status environments would display different deficits. Although this expectation may hold for phenotypic outcomes in older children and adults, cross-syndrome comparisons in infancy reveal many common neural and sociocognitive deficits. The challenge is to track dynamic trajectories over develop...

In this article, we discuss the complex problem of relating genotype to phenotype and challenge the simple mapping of genes to higher level cognitive modules. We examine various methods that have been used to investigate this relation including quantitative genetics, molecular genetics, animal models, and in-depth psychological and computational studies of developmental disorders. Both single g...
