In many domains, learners extract recurring units from continuous sequences. For example, in unknown languages, fluent speech is perceived as a continuous signal. Learners need to extract the underlying words from this continuous signal and then memorize them. One prominent candidate mechanism is statistical learning, whereby learners track how…

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…

This study adjudicates between two opposing accounts of morphological productivity, using English past-tense as its test case. The single-route model (e.g., Bybee & Moder, 1983) posits that both regular and irregular past-tense forms are generated by analogy across stored exemplars in associative memory. In contrast, the dual-route model…

Endel Tulving's distinction between "episodic" and "semantic" memory defines age differences in word association norms more comprehensively than the usual syntactic classifications. As subjects mature the principal development is an episodic-semantic shift. Young children associate primarily with the stimulus' perceived…

Transformational mnemonic strategies have been effectively used to enhance associative and serial list learning of borderline subjects classified as mentally retarded. Recent applications have involved concrete and abstract native-language vocabulary, numbered or ordered information, and digit span recall. (CB)

After intensively studying for several years the thinking processes of members of a tribal group in Western Africa, the Kpelle, the authors examine the relation between culture and cognitive development. The following issues are discussed: (1) an analysis of the terms "culture" and "cognition"; (2) an ethnographic description of the Kpelle…

Developed to improve the language skills of culturally disadvantaged preschool children, the activities can be adapted for use with the retarded or those with learning disabilities. Communication processes considered are derived from the Illinois Test of Psycholinguistic Abilities. Activities are described for the following areas: listening skills…

This collection of abstracts is part of a continuing series providing information on recent doctoral dissertations. The 25 titles deal with a variety of topics, including the following: reading achievement as it relates to child dependency, the development of phonological coding, short-term memory and associative learning, variables available in…

This document is the seventh report in the Language Research in Progress (LRIP) series, and lists a wide variety of language-related research projects current between April 1968 and November 1968. Research projects terminated in the six months prior to publication are included as well. Approximately 250 projects in the U.S. and abroad are…
