Causation is a core feature of human cognition and language. How children learn about intricate causal meanings is yet unresolved. Here, we focus on how children learn verbs that express causation. Such verbs, known as lexical causatives (e.g., break and raise), lack explicit morphosyntactic markers indicating causation, thus requiring that the…

The acquisition of quantifiers is a central topic in cognitive science. The present study investigated the emergence, frequency, and non-target-like production of the universal quantifiers "all," "every," and "each" in child English from a linguistic perspective, based on the data from longitudinal naturalistic…

The linguistic input children receive across early childhood plays a crucial role in shaping their knowledge about the world. To study this input, researchers have begun applying distributional semantic models to large corpora of child-directed speech, extracting various patterns of word use/co-occurrence. Previous work using these models has not…

The organization of our knowledge about the world into an interconnected network of concepts linked by relations profoundly impacts many facets of cognition, including attention, memory retrieval, reasoning, and learning. It is therefore crucial to understand how organized semantic representations are acquired. The present experiment investigated…

Teachers and parents intuitively judge the 'level' of the child and the 'level' of the text and try to match them; they know that overestimation or underestimation of either will be met with restlessness or boredom. In this way, they have an empirical understanding of Vygotsky's ZPD--the zone of proximal development he envisioned as measuring the…

Many sentences of adult English are analytic constructions, namely clauses with a matrix verb complemented by a dependent predicate that does not have an expressed syntactic subject. Examples are subject and object control, raising to subject or object, periphrastic tense, aspect and modality, copular predication and "do"-support. In…

Purpose: Most educational assessments tend to be constructed in a close-ended format, which is easier to score consistently and more affordable. However, recent work has leveraged computation text methods from the information sciences to make open-ended measurement more effective and reliable for older students. This study asks whether such text…

Children's production of bare nominals is universal. When acquiring languages disallowing bare nominals, children will develop from the bare to the non-bare stage. However, Mandarin nominals may appear bare or non-bare in various positions with all kinds of interpretations. This dissertation conducts two acquisition studies to examine the…

Recent evidence from adult pronoun comprehension suggests that semantic factors such as verb transitivity affect referent salience and thereby anaphora resolution. We tested whether the same semantic factors influence pronoun comprehension in young children. In a visual world study, 3-year-olds heard stories that began with a sentence containing…

This dissertation studies the acquisition of verb argument structure in the basilectal subvariety of Jakarta Indonesian (henceforth, bJI). There are two characteristics of bJI that potentially affect the acquisition of verb argument structure. First, bJI sentences can surface not only in the full frame but also in truncated frames. Second, the…

This study examined information about adjective meanings available in adults' spoken discourse in the original 27 CHILDES corpora of typically developing English-speaking children. In order to increase the probability that adjectives would be novel to children to whom they were addressed, only "rare" adjectives were examined (those that occurred…

McCormack and Hoerl's state of the art review of the development of temporal concepts from the end of infancy to the end of the fifth year shows that young children's conception of time is quite different from that of adults. Adults and 5-year-old children can construe an event from a range of temporal perspectives and can describe it from a…

The meaning of children's lexical innovations is distinguished from the forms they rely on to convey meaning. Children require knowledge of the context in order to judge how the meaning of their innovation can be conveyed to the addressee. This contextualization is often achieved by default, since children tend to limit their early conversations…

Discusses information theory and the notions of uncertainty and semantic choice in child language. (AM)

Reports on a study of three children's single-word responses to parents' questions, focusing on the interrelations between children's ability to answer questions, the types of semantic content used in appropriate and inappropriate answers, and questions asked by the parents. (Author/AM)
