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)
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)
This paper discusses successes and failures of computational linguistics techniques in the study of how inter-event time intervals in a story affect the narrator's use of different types of referring expressions. The success story shows that a conditional frequency distribution analysis of proper nouns and pronouns yields results that are consistent with(More)
Biolinguistics aims to shed light on the specifically biological nature of human language focusing on five foundational questions: (1) What are the properties of the language phenotype? (2) How does language ability grow and mature in individuals? (3) How is language put to use? (4) How is language implemented in the brain? (5) What evolutionary processes(More)
In this paper I argue that genetic studies of language provide insights about the evolution of language. The finding that genetic factors affect all aspects of language is consistent with theories that argue that language is at least partially the result of innate factors, and that the factors have evolved. Genetic factors appear to play a greater role for(More)
Prenatal exposure to excessive amounts of glucocorticosteroids (GCs) adversely affects the neural development and subsequent behavior of animals (see Matthews, 2000). Despite this, women who are likely to delivery prematurely are routinely given prenatal GCs because they decrease morbidity and mortality in preterm (PT) infants. Between 1994 and 2000, there(More)
Although twin studies clearly demonstrate that genetic factors play an important role in language acquisition, some twin studies suggest that adverse prenatal (Koeppen-Schomerus et al., 2000) or postnatal (Turkheimer et al., 2003) environments can overshadow the effects of genetic factors. The current study investigates, in the same group of twins, the(More)
This paper investigates the concurrent validity of the Parent Administered Language (PAL) test, a 10-minute test of preschool-aged children's articulation, lexical access, receptive vocabulary, and syntactic abilities. Parents of 122 racially and socioeconomically (SES) diverse children administered the PAL test to their child and an experimenter(More)
