In the past two decades, new research on multilingualism has changed our understanding of the consequences of learning and using two or more languages for cognition, for the brain, and for success and well-being across the entire lifespan. Far from the stereotype that exposure to multiple languages in infancy complicates language and cognitive…

The ability to acquire language is a critical part of human development. Yet there is no consensus on how the skill emerges in early development. Does it constitute an innately-specified, language-processing module or is it acquired progressively? One of Annette Karmiloff-Smith's (1938-2016) key contributions to developmental science addresses…

We investigate the hypothesis that our conceptual systems provide two formally distinct ways of representing categories by investigating the manner in which lexical nominals (e.g., "tree," "picnic table") and phrasal nominals (e.g., "black bird," "birds that like rice") are interpreted. Four experiments found that lexical nominals may be mapped…

Uncertainty was researched as a perceptual structure which mediates the transition from sensorimotor activity to language. The guiding notions are that the attentional system is geared to uncertainty from the beginning of life and that a speaker's language use is coordinated with this system as it emerges. (Author)

Nine papers were presented at a workshop concerned with structure and process in cognition. The reports given at this conference represent detailed applications of these concepts to limited areas of experience. This work is unique in that both structure and process appear together, rather than being studied as independent concepts. All the papers…

Examined effects of direct intervention on language learning. Using a toy manipulation task, 18 children aged 3;6 to 4;6 were systematically taught linguistic structures beyond their developmental grasp. Solid improvement was found in the experimental conditions; no significant improvement was noted in control conditions, showing that the language…

Children's understanding of the epistemological terms "know" and "guess" was investigated in two studies with four- to ten-year-old subjects. Two adult players guessed at the location of a ball hidden in one of two boxes. On each trial the child was asked questions about "knowing" and "guessing" both before and after the guessing took place.…

The relationship of object permanence and classification skills to receptive and expressive language development was investigated in infants. Object permanence, classification, and parent-child verbal interaction ratings were about equally related to language comprehension functioning, while permanence was more strongly related to language…

Reviews the literature of the research done in cognitive psychology and linguistics as it relates to psycholinguistics. Suggests that advances in various separate fields have been synthesized with their application to classroom instruction in reading and writing. (TJ)

This article discusses a study designed to determine the order of acquisition of the two expressions "in front of" and "behind," using two featureless objects. (CFM)

This paper reviews recent theoretical developments and empirical findings in the area of the development of word knowledge in children. Advances in both linguistic and cognitive theory are described and synthesized, and children's word knowledge at various stages of development is outlined. The point is made that asking meaningful questions about…

Major findings are reported of a longitudinal, naturalistic study of grammatical morpheme development in an aphasic child from 5;5 to 6;1. The majority of the morphemes were not acquired in the same order nor at the same mean length of utterance (MLU) levels reported for normal children. As an alternative to the normal acquisition model, based on…

The written compositions of 11-year-olds in Great Britain's National Child Development Study were analyzed using the T-unit length as a measure of syntactic maturity and composition length as a measure of productivity. Results are discussed in relation to cognitive and linguistic development. (Author/RM)

Forty-five children drawn equally from nursery school, kindergarten, and first grade were administered a nonverbal imitation task, a production task, a comprehension task, and a verbal imitation task. The results of the four tasks support the Temporal Complexity Hypothesis, which states that the components of temporality--order among events (O),…

Narrative observations were made of remedial interchanges occurring among school children (K-4) in open classrooms. Transcripts of interchanges were typed move by move and coded according to a hierarchical coding scheme (remedy, defiance, no response, relief, ending, and ambiguous). The interchanges of the kindergarteners and first graders were…
