Perceptual representations of objects and approximate magnitudes are often invoked as building blocks that children combine to acquire the positive integers. Systems of numerical perception are either assumed to contain the logical foundations of arithmetic innately, or to supply the basis for their induction. I propose an alternative to this…

Establishing local coherence relations is central to text comprehension. Positive-causal coherence relations link a cause and its consequence, whereas negative-causal coherence relations add a contrastive meaning (negation) to the causal link. According to the cumulative cognitive complexity approach, negative-causal coherence relations are…

Recent studies on the acquisition of semantics have argued that knowledge of the universal quantifier is adult-like throughout development. However, there are domains where children still exhibit non-adult-like universal quantification, and arguments for the early mastery of relevant semantic knowledge do not explain what causes such…

To investigate the apparent delay in color naming by young children, this study compared natural-kind and color naming (and corresponding comprehension) by 48 young English children who completed testing four times over six weeks. Results indicated that, as opposed to the salience view, the apparent delay in color naming may be explained solely on…

Through discussion and illustrative events, an evolving segment of communication is described during the course of transition of one child's total communication system from the sensorimotor or gestural level at 12 months into the level of use of the adult words "more" and "mine," and associated utterances, at 24 months.

Describes a study done to determine whether the degree of children's familiarity with component words was related to (1) their ability to produce productive patterns as opposed to associative and grouping patterns, and (2) their ability to use broader scope rather than lexically based patterns. (SED)

Describes the presence of a phonological selection strategy and consonant harmony rule in one child's developing phonological system. Evidence suggests that this constant harmony constraint operated across morpheme boundaries, causing a delay in the onset of two-word utterances and influencing the selection of words that could occur in word…
