Gray, Shelley; Lancaster, Hope; Alt, Mary; Hogan, Tiffany P.; Green, Samuel; Levy, Roy; Cowan, Nelson – Journal of Speech, Language, and Hearing Research, 2020
Purpose: We investigated four theoretically based latent variable models of word learning in young school-age children. Method: One hundred sixty-seven English-speaking second graders with typical development from three U.S. states participated. They completed five different tasks designed to assess children's creation, storage, retrieval, and…

Connor, Carol McDonald; Day, Stephanie L.; Phillips, Beth; Sparapani, Nicole; Ingebrand, Sarah W.; McLean, Leigh; Barrus, Angela; Kaschak, Michael P. – Child Development, 2016
Many assume that cognitive and linguistic processes, such as semantic knowledge (SK) and self-regulation (SR), subserve learned skills like reading. However, complex models of interacting and bootstrapping effects of SK, SR, instruction, and reading hypothesize reciprocal effects. Testing this "lattice" model with children (n = 852)…

Kieffer, Michael J.; Vukovic, Rose K. – Journal of Learning Disabilities, 2012
Drawing on the cognitive and ecological domains within the componential model of reading, this longitudinal study explores heterogeneity in the sources of reading difficulties for language minority learners and native English speakers in urban schools. Students (N = 150) were followed from first through third grade and assessed annually on…

Puolakanaho, Anne; Ahonen, Timo; Aro, Mikko; Eklund, Kenneth; Leppanen, Paavo H. T.; Poikkeus, Anna-Maija; Tolvanen, Asko; Torppa, Minna; Lyytinen, Heikki – Journal of Learning Disabilities, 2008
The authors examined second grade reading accuracy and fluency and their associations via letter knowledge to phonological and language predictors assessed at 3.5, 4.5, and 5.5 years in children in the Jyvaskyla Longitudinal Study of Dyslexia. Structural equation modeling showed that a developmentally highly stable factor (early phonological and…
