Positron Emission Tomography (PET) was used to determine regional cerebral blood flow (rCBF) when eight normal right-handed males read and made acceptability judgments about sentences. rCBF was greater in Broca's area (particularly in the pars opercularis) when subjects judged the semantic plausibility of syntactically more complex sentences as compared to(More)
Some researchers argue that the ability to acquire and use language is largely the result of innate predispositions that are specific to language (the INNATENESS HYPOTHESIS). If the innateness hypothesis is correct, these predispositions must be encoded for in our DNA. This article reviews more than one hundred genetic studies of language. The results of(More)
Results of twin studies clearly demonstrate that genetic factors play an important role in the rate of language acquisition and linguistic proficiency attained by normal and impaired children and adults [see Stromswold, K. (2001). The heritability of language: A review and meta-analysis of twin, adoption and linkage studies. Language, 77, 647-723.]. That(More)
If language is the result of specialized structures in the brain and if these language-specific structures are genetically encoded, one would expect to find evidence of the heritability of language. In this article I review the results of family aggregation, pedigree, sex ratio, commingling, and segregation studies of spoken language disorders. The results(More)
In two eye-tracking experiments, we investigate adults' and children's on-line processing of referentially ambiguous English pronouns. Sixteen adults and 16 four-to-seven-year-olds listened to sentences with either an unambiguous reflexive (himself) or an ambiguous pronoun (him) and chose a picture with two characters that corresponded to those in the(More)
Without instruction, most children master the complexities of spoken language by the age of 6 or 7 years. About 5% of apparently healthy children, however, struggle to acquire basic competence in one or more aspects of spoken language and are classified as having specific language impairment. Genetic factors have an important role in many such cases.1,2(More)
Our goal in this article is to review a debate over the evolution of language and to suggest some keys to its resolution. We begin with a review of some of the theoretical and empirical evidence for the innateness of language that has caused renewed interest in the evolution of language. In a second section we review some prominent theories of the evolution(More)
The most common method used to study the role of genetic factors for in development is to determine whether monozygotic (MZ) cotwins are linguistically more similar to one another than dizygotic (DZ) cotwins. Because MZ and DZ cotwins share essentially the same preand postnatal environment, whereas MZ cotwins share 100% of their DNA and DZ cotwins share(More)
This paper investigates how detailed a linguistic representation is formed for descriptions of visual events. In two experiments, participants watched captioned videos and decided whether the captions accurately described the videos. In both experiments, videos depicted geometric shapes moving around the screen. In the first experiment, all of the captions(More)
Focus below the word level (e.g. Jill only brought home a stalagMITE from the cave) and coordination of parts of words (ortho and periodontists) show that the compositional processes of focus and coordination apply to units that lack an independent meaning. Such constructions are interpreted through phonological decomposition, which assigns denotations to(More)
