Infant categorization as a dynamic process linked to memory

Working Memory Capacity as a Dynamic Process

A well-known characteristic of working memory (WM) is its limited capacity. The source of such limitations, however, is a continued point of debate. Developmental research is positioned to address this debate by jointly identifying the source(s) of limitations and the mechanism(s) underlying capacity increases. Here we provide a cross-domain survey of studies and theories of WM capacity develop...

Modeling Categorization as a Dirichlet Process Mixture

I describe an approach to modeling the dynamics of human category learning using a tool from nonparametric Bayesian statistics called the Dirichlet process mixture model (DPMM). The DPMM has a number of advantages over traditional models of categorization: it is interpretable as the optimal solution to the category learning problem, given certain assumptions about learners’ biases; it automatic...

Dynamic Categorization of Semantics of Fashion Language: A Memetic Approach

Categories are not invariant. This paper attempts to explore the dynamic nature of semantic category, in particular, that of fashion language, based on the cognitive theory of Dawkins’ memetics, a new theory of cultural evolution. Semantic attributes of linguistic memes decrease or proliferate in replication and spreading, which involves a dynamic development of semantic category. More specific...

The Importance of Long-term Memory in Infant Perceptual Categorization

Quinn and Eimas (1998) reported that young infants include non-human animals (i.e., cats, horses, and fish) in their category representation for humans. To account for this surprising result, it was proposed that the representation of humans by infants functions as an attractor for non-human animals and is based on infants’ previous experience with humans. We report three simulations that provi...
