Children often interpret first noun phrases (NP1s) as agents, which improves comprehension of actives but hinders passives. While children sometimes withhold the agent-first bias, the reasons remain unclear. The current study tests the hypothesis that children default to the agent-first bias as a "best guess" of role assignment when they…

This research examined how linguistic differences between African American English (AAE) and Mainstream American English (MAE) impact how children process sentences and learn new information. The central hypothesis of this dissertation is that these linguistic differences adversely impact how AAE-speaking children use contrastive inflectional verb…

Background & aims: Throughout typical development, children prioritize different perceptual, social, and linguistic cues to learn words. The earliest acquired words are often those that are perceptually salient and highly imageable. Imageability, the ease in which a word evokes a mental image, is a strong predictor for word age of acquisition…

The early use of first and second person pronouns has been viewed as a sign of emerging social understanding. However, it may also depend on general language development: pronouns do not appear among the first words children acquire. In addition, some languages conjugate verbs for person, and the inflections may thus show similar relations to…

Sixty-eight undergraduate translation students received direct instruction in the features of news headlines and news stories. A week later, they took a test that required them to identify the syntactic and lexical features of a sample of news headlines and news stories, supply deleted word, and substitute punctuation marks, infinitives, and block…

Many studies have demonstrated that listeners use information extracted from verbs to guide anticipatory eye movements to objects in the visual context that satisfy the selection restrictions of the verb. An important question is what underlies such verb-mediated anticipatory eye gaze. Based on empirical and theoretical suggestions, we…

Using the blocked-translation paradigm with healthy participants, we examined Crutch and Warrington's hypothesis that concrete and abstract concepts are organized by distinct principles: concrete concepts by semantic similarities and abstract ones by associations. In three experiments we constructed two types of experimental blocking (similar…

Babcok et al. (2012) claim that Paradis (1994, 2004, 2009) argues that the reliance of late L2 learners on L1 neurocognitive mechanisms increases over time across both lexical and grammatical functions, namely for lexical items as well as rule-governed grammatical procedures, when in fact one can find repeated statements to the contrary in the…

Previous research on event-related potentials (ERPs) on second language processing has revealed a great degree of plasticity in brain mechanisms of adult language learners. Studies with natural and artificial languages show that the N400 as well as the P600 component appear in learners after sufficient training. The present experiment tests if and…

What does mass-count syntax contribute to the interpretation of noun phrases (NPs), and how much of NP meaning is contributed by lexical items alone? Many have argued that count syntax specifies reference to countable individuals (e.g., "cats") while mass syntax specifies reference to unindividuated entities (e.g., "water"). We evaluated this…

There is little agreement on the mechanisms involved in second language (L2) processing of regular and irregular inflectional morphology and on the exact role of age, amount, and type of exposure to L2 resulting in differences in L2 input and use. The article contributes to the ongoing debates by reporting the results of two experiments on Russian…

The purpose of this study was to examine within- and across-language relationships between lexical and grammatical domains by focusing on measures of lexical diversity and grammatical complexity in Spanish and English. One hundred ninety-six preschool and school-aged Latino children with different levels of English and Spanish proficiencies and…

Although the organization of first language (L1) and second language (L2) lexicosemantic information has been extensively studied in the bilingual literature, little evidence exists concerning how syntactic information associated with words is represented across languages. The present study examines the shared or independent nature of the…

In the study reported here, Japanese-speaking children aged 3-6 were confronted with making choices based on conflicting input from speakers who varied in the degree of certainty and the quality of evidence they possessed for their opinions. Certainty and evidentiality are encoded in Japanese both in high-frequency, closed-class, sentence-final…

Selective verb and noun deficits have been observed in a number of neurological conditions and their occurrence has been interpreted as evidence for different neural networks underlying the processing of specific word categories. We describe the first case of a familial occurrence of a selective deficit of verb processing. Father (Individual I)…
