Previous research indicates that infants generalize syntactic-like structures to novel exemplars in a way that has been characterized as abstract and algebraic (Marcus et al., 1999). Infants appear to learn and generalize from speech more successfully than from nonspeech stimuli (Marcus, Fernandes, & Johnson, 2007). In this series of experiments,…

To evaluate the orthographic and phonological processing skills of developmental dyslexics, we (a) examined their abilities to exploit properties of orthographic redundancy and (b) tested whether their phonological deficit extends to spelling-to-sound connections for large-grain size units such as syllables. To assess the processing skills in…

Notes that three papers and commentary (in this issue) emphasized importance of including data on manual modality when studying language development and its relationship to other domains. Discusses advantages of using robustness analysis rather than precursor relations to study domain relations. Suggests alternative theoretical context to which…

Investigates why young children become redundant and informative speakers after listening to nonredundant and informative speakers. The authors conclude that children confuse the length of a message with information. (Author/DB)

Seven-month-old infants require redundant information such as temporal synchrony to learn arbitrary syllable-object relations. Infants learned the relations between spoken syllables, /a/ and /i/, and two moving objects only when temporal synchrony was present during habituation. Two experiments examined infants' memory for these relations. In…

Words artificially isolated from 12 parents' speech to their children aged 1;10-3;0 were significantly less intelligible to adult listeners than words originally spoken to an adult. While parents did not adjust the clarity of words, their speech was more redundant in anticipation of the children's comprehension. Research implications are…

This article hypothesizes that language repetition of young children (in the sense used by Kobashigawa and Snow) does not help language acquisition. The evidence comes from the results of a prior study in which no indication was found that mothers who repeat themselves a great deal have children who acquire language more quickly. However,…
