The psychology supporting the use of quantifier words (e.g., "some," "most," "more") is of interest to both scientists studying quantity representation (e.g., number, area) and to scientists and linguists studying the syntax and semantics of these terms. Understanding quantifiers requires both a mastery of the…

Generics are sentences such as "ravens are black" and "tigers are striped", which express generalizations concerning kinds. Quantified statements such as "all tigers are striped" or "most ravens are black" also express generalizations, but unlike generics, they specify how many members of the kind have the property in question. Recently, some…

When students learn scientific theories that conflict with their earlier, naive theories, what happens to the earlier theories? Are they overwritten or merely suppressed? We investigated this question by devising and implementing a novel speeded-reasoning task. Adults with many years of science education verified two types of statements as quickly…

By age 2, children attribute referential mental states such as perceptions and emotions to themselves and others, yet it is not until age 4 that they attribute representational mental states such as beliefs. This raises an interesting question: is attribution of beliefs different from attribution of perceptions and emotions in terms of its neural…

Clahsen and Felser (CF) analyze the performance of monolingual children and adult second language (L2) learners in off-line and on-line tasks and compare their performance with that of adult monolinguals. They conclude that child first language (L1) processing is basically the same as adult L1 processing (the contiguity assumption), with…

This follow-up study compares cognitive and language aspects of a group of Italian children ages 4-6 years, who had shown delayed expressive language abilities at 24 months of age (late talkers), with those of a group of children with a history of normal expressive language development (average talkers). Children were given a battery of…

Examines the ability of young and older adults with mild to moderate mental retardation to produce complex sentences in naturalistic conversation. The complex sentences produced were coded into subcategories of complementation, relativization, or coordination and then analyzed. No significant differences were observed between the two age groups.…

A study was conducted to determine whether children give evidence of using any of six comprehension strategies and whether children of same and different ages use different strategies. It was studied how comprehension performance can best be predicted by other facts about the child, including his language and his language input. The six…

Investigates the availability of syntactic cues to verb meaning. In Experiments 1-3, adult subjects' judgments of verbs' semantic similarity were compared with other adults' judgments about the syntactic properties of the same verbs. In Experiment 4, subjects paraphrased sentences formed by pairing verbs with unaccustomed sentence frames. (54…

Investigates the relative influences of medium and context variables by comparing seven- and eight-year-old children's spoken and written explanations in varying contexts: a story task, a question task, a sentence completion task, and a whole sentence production task. Findings reveal the significant influence of context as compared to medium on…

An analysis of the use of attenuation (structural or semantic softening of the speech act) and sentence structure in elicited speech acts by normally developing, learning disabled, and developmentally delayed populations is presented. In the normally developing population (1) the development of attenuation strategies is different from structural…
