Why do infants learn some words earlier than others? Many theories of early word learning focus on explaining how infants map labels onto concrete objects. However, words that are more abstract than object nouns, such as "uh-oh," "hi," "more," "up," and "all-gone," are typically among the first to…

The morphological structure of complex words impacts how they are processed during visual word recognition. This impact varies over the course of reading acquisition and for different languages and writing systems. Many theories of morphological processing rely on a decomposition mechanism, in which words are decomposed into explicit…

Infants build knowledge by acting on the world. We conducted an ecologically grounded test of an embodied learning hypothesis: that infants' active engagement with objects in the home environment elicits caregiver naming and cascades to learning object names. Our home-based study extends laboratory-based theories to identify real-world processes…

Learning new words is fundamental in both first and second-language reading. There are, however, divided opinions on the best instructional approaches. Two widely used approaches across languages are whole-word focus and word-constituent focus. The appropriateness of each approach has varied historically, even within a single language (e.g., the…

In this paper, we investigate the effect of neighbourhood density (ND) on vocabulary size in a computational model of vocabulary development. A word has a high ND if there are many words phonologically similar to it. High ND words are more easily learned by infants of all abilities (e.g. Storkel, 2009; Stokes, 2014). We present a neural network…

Age of acquisition (AoA) refers to the age at which people learn a particular item and the AoA effect refers to the phenomenon that early-acquired items are processed more quickly and accurately than those acquired later. Over several decades, the AoA effect has been investigated using neuroscientific, behavioral, corpus and computational…

Many approaches to early word learning posit that children assume a one-to-one mapping of form and meaning. However, children's early vocabularies contain homophones, words that violate that assumption. Children might learn such words by exploiting prosodic differences between homophone meanings that are associated with lemma frequency (Gahl,…

This article focuses on the acquisition of mood in early complement clauses of European Portuguese (EP). Two semantic features are involved in the EP mood system--epistemicity and veridicality. An elicited production task administered to 80 children aged 4 to 9 showed that, even though children use the subjunctive in [-- epistemic] contexts, the…

Conceptual metaphor theory (CMT) proposes that there is a large system of conceptual metaphors in our cognition known as event-structure metaphors (ESMs). Through ESMs, we understand the conceptual domains of actions, causes, changes, states, purposes, and so forth in terms of the aspects of the domain of motion in space. ESMs are largely…

This paper represents an attempt to conduct a corpus-based stylistic analysis of two conceptual metaphors in "The Unbearable Lightness of Being," which is a novel written by Milan Kundera. "Soul-body" and "lightness-heaviness" metaphors are foregrounded as being central themes all through the novel. The way such…

Arbitrary symbolism is a linguistic doctrine that predicts an orthogonal relationship between word forms and their corresponding meanings. Recent corpora analyses have demonstrated violations of arbitrary symbolism with respect to concreteness, a variable characterizing the sensorimotor salience of a word. In addition to qualitative semantic…

Each of us as language learners had different language experiences, yet somehow we have converged upon broadly the same language system. From diverse, often noisy samples, we have attained similar linguistic competence. How so? What mechanisms channel language acquisition? Could our linguistic commonalities possibly have converged from our shared…

This paper examines the impact of L1/L2 form-meaning differences in the domain of aspect to investigate whether L2 learners are able to acquire properties of the L2 that are different from the L1. Oral data were collected from English- and German-speaking university learners of French L2 (n = 75) at two different levels of proficiency. The results…

It is often assumed that graphemes are a crucial level of orthographic representation above letters. Current connectionist models of reading, however, do not address how the mapping from letters to graphemes is learned. One major challenge for computational modeling is therefore developing a model that learns this mapping and can assign the…

Learning to read in any language requires learning to map among print, sound and meaning. Writing systems differ in a number of factors that influence both the ease and the rate with which reading skill can be acquired, as well as the eventual division of labor between phonological and semantic processes. Further, developmental reading disability…
