We inquired whether introducing variability into a word-learning task would facilitate, inhibit, or have a neutral effect on adults' speech production and language learning. Twenty young adults from the U.S. Midwest with typical development participated. They repeated four novel words 10 times sequentially (blocked practice) and another four novel…

Language development is frequently characterized as a process where learning proceeds implicitly, that is, incidentally and in absence of awareness of what was learned. This article reports the results of two experiments that investigated whether second language acquisition can also result in implicit knowledge. Adult learners were trained on an…

This review explores the literacy difficulties experienced by prelingual, profoundly deaf, sign-dominant adults. A critical overview of the existing literature identifies the importance of understanding their language experiences and word-coding preferences. Findings challenge the notion that a permanent lack of audition from birth prevents…

A study of near-native sentence processing was carried out using the self-paced reading method. Twenty-three near-native speakers of Spanish were identified on the basis of native-like proficiency, age of onset of acquisition after 15 years, and a minimum of three years ongoing residency in Spanish-speaking countries. The sentence comprehension…

A fundamental assumption regarding spoken language is that the relationship between sound and meaning is essentially arbitrary. The present investigation questioned this "arbitrariness" assumption by examining the influence of potential non-arbitrary mappings between sound and meaning on word learning in adults. Native English-speaking…

When language learners are exposed to inconsistent probabilistic grammatical patterns, they sometimes impose consistency on the language instead of learning the variation veridically. The authors hypothesized that this regularization results from problems with word retrieval rather than from learning per se. One prediction of this, that easing the…

When natural language input contains grammatical forms that are used probabilistically and inconsistently, learners will sometimes reproduce the inconsistencies; but sometimes they will instead regularize the use of these forms, introducing consistency in the language that was not present in the input. In this paper we ask what produces such…
