Three experiments tested theories of syntactic representation by assessing "stem-exchange" errors ("hates the record"[right arrow]"records the hate"). Previous research has shown that in stem exchanges, speakers pronounce intended nouns ("REcord") as verbs ("reCORD"), yielding syntactically well-formed utterances. By "lexically based" theories,…

We show that 4-year-olds assign the correct interpretation to antecedent-contained deletion (ACD) sentences because they have the correct representation of these structures. This representation involves Quantifier Raising (QR) of a Quantificational Noun Phrase (QNP) that must move out of the site of the verb phrase in which it is contained to…

We present four experiments on the interpretation of pronouns and reflexives in picture noun phrases with and without possessors (e.g. "Andrew's picture of him/himself, the picture of him/himself"). The experiments (two off-line studies and two visual-world eye-tracking experiments) investigate how syntactic and semantic factors guide the…

The theory of syntactic bootstrapping proposes that children can use syntax to infer the meanings of words. This paper presents experimental evidence that children are also able to use word inflections to infer word reference. Twenty-four- and 30-month-olds were tested in a preferential looking experiment. Children were shown a pair of novel…

This study explored learning and generalization of parts of the Russian case-marking paradigm, an inflecting-fusional system in which affixes simultaneously mark several grammatical features (case, gender, number, animacy). In Experiment 1, adult English speakers (N = 43) were exposed to nouns with transparent gender marking in the nominative case…

Two experiments investigated the factors that govern children's use of singular and plural forms of count nouns. Experiment 1 used an elicited production task to investigate whether children use referential and/or syntactic information to determine the form of the count nouns when the two sources of information conflict (e.g. "each x, one of the…

Seventeen native English speakers participated in an investigation of language users' knowledge of English main stress patterns. First, they produced 40 two-syllable nonwords of varying syllabic structure as nouns and verbs. Second, they indicated their preference for first or second syllable stress of the same words in a perception task. Finally,…

The experiments reported here were designed to investigate the influence of stress typicality during speeded grammatical classification of disyllabic English words by native and non-native speakers. Trochaic nouns and iambic verbs were considered to be typically stressed, whereas iambic nouns and trochaic verbs were considered to be atypically…
