Do children learn a new word by tracking co-occurrences between words and referents across multiple instances ("cross-situational learning" models), or is word-learning a "one-track" process, where learners maintain a single hypothesis about the possible referent, which may be verified or falsified in future occurrences…

A primary objective of development is to build a knowledge base. To accumulate knowledge over time and experiences, learners must engage in productive processes, going beyond what is explicitly given to generate new knowledge. Though important to accumulating knowledge, these processes are also easily disrupted. Individuals often depend on surface…

In recent years, the intersection of cognitive psychology, developmental psychology, and neuroscience with regard to deaf individuals has received increasing attention from a variety of academic and educational audiences. Both research and pedagogy have addressed questions about whether deaf children learn in the same ways that hearing children…

Recent research is reviewed demonstrating positive effects of bilingualism on cognitive development, some explanation of this research are given, and an interpretation is offered bearing on the variability of memory codes in bilinguals. Results of a study dealing with memory codes are presented and discussed. (Text is in French.) (AMH)

Mental activities and information learned in one context are not necessarily available for use in another. They often have to be learned anew in the second context, although perhaps with less time and effort. The fact is, however, that relatively little is known about how the activities of the mind affect one another. The study of bilingualism,…

Two experiments are reported in which mismatched sounds and spelling were studied in Dutch pseudo-words used as stimuli in English lexical decision experiments. Results show mismatches in spelling or sound result in longer latencies for Dutch pseudo-words than for their nonword controls, supporting a cooperation model of lexical access. (MSE)

A framework for describing relationships among the different linguistic systems in a bilingual or second language learner is proposed. The framework attempts to represent the ways in which knowledge of one language is used in integrating into memory new knowledge about another language. The model is partially implemented in a computer program that…
