Caselli, Naomi K.; Pyers, Jennie E. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2020
Lexical iconicity--signs or words that resemble their meaning--is overrepresented in children's early vocabularies. Embodied theories of language acquisition predict that symbols are more learnable when they are grounded in a child's firsthand experiences. As such, pantomimic iconic signs, which use the signer's body to represent a body, might be…

Borovsky, Arielle – Developmental Psychology, 2022
Toddlerhood is marked by advances in several lexico-semantic skills, including improvements in the size and structure of the lexicon and increased efficiency in lexical processing. This project seeks to delineate how early changes in vocabulary size and vocabulary structure support lexical processing (Experiment 1), and how these three skills…

MacRoy-Higgins, Michelle; Shafer, Valerie L.; Fahey, Katlin J.; Kaden, Elyssa R. – Journal of Early Intervention, 2016
The purpose of this study was to understand vocabulary characteristics in toddlers who are late talkers (LT) as compared with age-matched (AM) and vocabulary-matched (VM) peers. The semantic categories (e.g., animals, foods, toys) and the percentage of nouns, verbs, and closed-class words in the vocabularies of 36 toddlers (12 LT, 12 AM, 12 VM)…

Schults, Astra; Tulviste, Tiia – First Language, 2016
The growth rate and the composition of expressive lexicon was studied in a sample of 903 infants between the age of 0;8 and 1;4 whose parents completed the Estonian adaptation of the MacArthur-Bates Communicative Development Inventory-Words and Gestures. As expected, older children had on average larger vocabularies compared to younger children.…

Singleton, Nina Capone – American Journal of Speech-Language Pathology, 2012
Purpose: This study examined the relationship between semantic enrichment and naming in children asked to extend taught words to untrained exemplars. Method: Sixteen typically developing children ( M = 32.63 months, SD = 4.02) participated in 3 word learning conditions that varied semantic enrichment via iconic (shape, function) or point gesture.…
