In response to Golinkoff, Hoff, Rowe, Tamis-LeMonda, and Hirsh-Pasek's (2018) commentary, we clarify our goals, outline points of agreement and disagreement between our respective positions, and address the inadvertently harmful consequences of the word gap claim. We maintain that our study constitutes a serious empirical challenge to the word…

Kathy Hirsh-Pasek is the Stanley and Debra Lefkowitz Faculty Fellow in the Department of Psychology at Temple University and a Senior Fellow at the Brookings Institution. She is the past president of the International Society for Infant Studies, served as the Associate Editor of "Child Development" and is on the governing counsel of the…

Ambridge argues that there is widespread agreement among child language researchers that learners store linguistic abstractions. In this commentary the authors first argue that this assumption is incorrect; anti-representationalist/exemplar views are pervasive in theories of child language. Next, the authors outline what has been learned from this…

A systematic review was conducted to synthesize the evidence related to the effectiveness of baby sign language for children with typical development. This response to a Commentary on the review stresses that the primary purpose of the review was to assist caregivers and policy makers with informed decision-making related to the benefits of the…

John McDowell begins his essay "Knowledge by Hearsay" (1993) by describing two ways language matters to epistemology. The first is that, by understanding and accepting someone else's utterance, a person can acquire knowledge. This is what philosophers call "knowledge by testimony." The second is that children acquire knowledge in the course of…

How do children learn the meanings of number words like "one," "two," and "three"? Whereas many words that children learn in early acquisition denote individual things and their properties (e.g., cats, colors, shapes), numerals, like quantifiers, denote the properties of sets. Unlike quantifiers such as "several" and "many," numerals denote…

In this article it is argued that the development of young people's skills in using spoken language should be given more time and attention in the school curriculum. The author discusses the importance of the effective use of spoken language in educational and work settings, considers what research has told us about the factors that make group…

We applaud Stoel-Gammon's (this issue) call for a more comprehensive account of the relationship between lexicon and phonology, and we strongly endorse her suggestions for future research. However, we think that it will not be enough simply to integrate findings and methods from the adult-centered and child-centered literatures. Both of these…

Carol Stoel-Gammon has made a real contribution in bringing together two fields that are not generally jointly addressed. Like Stoel-Gammon, we have long focused on individual differences in phonological development (e.g. Vihman, Ferguson & Elbert, 1986; Vihman, Boysson-Bardies, Durand & Sundberg, 1994; Keren-Portnoy, Majorano & Vihman, 2008). And…

When Roger Brown selected Adam, Eve and Sarah to be the first three participants in the modern study of child language, one of the criteria was the intelligibility of their speech (Brown, 1973). According to the prevailing view at the time, accuracy of pronunciation was a peripheral phenomenon that had nothing to do with the development of…

Stoel-Gammon (this issue) states that "from birth to age 2 ; 6, the developing phonological system affects lexical acquisition to a greater degree than lexical factors affect phonological development" (this issue). This conclusion is based on a wealth of data; however, the available data are somewhat limited in scope, focusing on rather holistic…

Stoel-Gammon (this issue) provides a welcome addition to the phonological acquisition literature, bringing together insights from long-standing and more recent research to address the relationship between the developing phonological system and the developing lexicon. A growing literature on children's early use of words across languages and…

Within the subfields of linguistics, traditional approaches tend to examine different phenomena in isolation. As Stoel-Gammon (this issue) correctly states, there is little interaction between the subfields. However, for a more comprehensive understanding of language acquisition in general and, more specifically, lexical and phonological…

This paper presents an interview with Dr. Alice Sterling Honig which took place in Syracuse, New York, in May 2009. Michele Jachim Barrett of Syracuse University conducted the interview using questions prepared by the editors of "ECRP." Dr. Honig is currently Professor Emerita at Syracuse University. Her work in early childhood development, care,…

Stoel-Gammon (this issue) highlights the close and symbiotic association that exists between the lexical and phonological domains in early linguistic development. Her comprehensive review considers two bodies of literature: (1) child-centred studies; and (2) studies based on adult psycholinguistic research. Within the child-centred studies, both…
