We comment on Goldstein, Davidoff, and Roberson's replication and extension ("Journal of Experimental Child Psychology, 102", 219-238 [2009]) of our study of the effect of toddlers' color term knowledge on their categorical perception (CP) of color ("Journal of Experimental Child Psychology, 90", 114-141 [2005]). First, we discuss how best to…

Forty toddlers aged 20 to 24 months were presented with 32 pairs of images with the auditory stimulus Look followed by the name of the target image (e.g. "Look...tree") in an intermodal preferential looking (IPL) paradigm. The same series of 16 items was presented first with one image as target and then with the other member of the pair as target.…

This study assessed the influence of a 10-week parent-child intervention group on the vocabulary development of 10 late-talking toddlers. Results demonstrated the efficacy of the focused stimulation approach in increasing overall and target vocabulary acquisition. Parents reported satisfaction with the program in terms of the child's vocabulary…

Describes short-form versions of the MacArthur Communicative Development Inventories (CDIs) and their development, summarizes newly available normative data and psychometric properties of the instruments, and discusses research and clinical applications. (Author/VWL)

Language and reading outcomes at 13 years of age were examined in 28 children identified at 24 to 31 months as late talkers, all of whom came from middle--to upper-class socioeconomic status (SES) families and had normal nonverbal ability and age-adequate receptive language at intake. Late talkers were compared with a group of 25 typically…

Toddlers in the lowest 10th percentile for lexical production were compared with age- and language-matched controls on measures of phonetic complexity, lexical development, and grammatical complexity. Results indicate an overlap between phonology, lexicon, and grammar and suggest the importance of true consonant production for lexical development.…
