Exploring the Machine Learning Paradigm in Determining Risk for Reading Disability
Peer reviewed Peer reviewed
Direct linkDirect link
Erbeli, Florina; He, Kai; Cheek, Connor; Rice, Marianne; Qian, Xiaoning – Scientific Studies of Reading, 2023
Purpose: Researchers have developed a constellation model of decodingrelated reading disabilities (RD) to improve the RD risk determination. The model's hallmark is its inclusion of various RD indicators to determine RD risk. Classification methods such as logistic regression (LR) might be one way to determine RD risk within the constellation…

Magnocellular Pathway and Reading Rate: An Equivalence Test Analysis
Peer reviewed Peer reviewed

Edwards, Ashley A.; Schatschneider, Christopher – Scientific Studies of Reading, 2020
Previous research has revealed conflicting results with regard to the role of the magnocellular visual system in reading and dyslexia. In order to investigate this further, the present study examined the relationship between performance on two magnocellular tasks (temporal gap detection and coherent motion), reading rate (oral and silent), and…

Using Simulations to Investigate the Longitudinal Stability of Alternative Schemes for Classifying and Identifying Children with Reading Disabilities
Peer reviewed Peer reviewed
Direct linkDirect link
Schatschneider, Christopher; Wagner, Richard K.; Hart, Sara A.; Tighe, Elizabeth L. – Scientific Studies of Reading, 2016
The present study employed data simulation techniques to investigate the 1-year stability of alternative classification schemes for identifying children with reading disabilities. Classification schemes investigated include low performance, unexpected low performance, dual-discrepancy, and a rudimentary form of constellation model of reading…

Examining the Etiology of Reading Disability as Conceptualized by the Hybrid Model
Peer reviewed Peer reviewed
Direct linkDirect link
Erbeli, Florina; Hart, Sara A.; Wagner, Richard K.; Taylor, Jeanette – Scientific Studies of Reading, 2018
A fairly recent definition of reading disability (RD) is that in the form of a hybrid model. The model views RD as a latent construct that is manifested through various observable unexpected impairments in reading-related skills and through inadequate response to intervention. The current report evaluated this new conceptualization of RD from an…

Text (Oral) Reading Fluency as a Construct in Reading Development: An Investigation of Its Mediating Role for Children from Grades 1 to 4
Peer reviewed Peer reviewed
Direct linkDirect link
Kim, Young-Suk Grace; Wagner, Richard K. – Scientific Studies of Reading, 2015
In the present study we investigated a developmentally changing role of text reading fluency in mediating the relations of word reading fluency and listening comprehension to reading comprehension. We addressed this question by using longitudinal data from Grades 1 to 4 and employing structural equation models. Results showed that the role of text…

Relations among Oral Reading Fluency, Silent Reading Fluency, and Reading Comprehension: A Latent Variable Study of First-Grade Readers
Peer reviewed Peer reviewed
Direct linkDirect link
Kim, Young-Suk; Wagner, Richard K.; Foster, Elizabeth – Scientific Studies of Reading, 2011
In the present study, we examined oral and silent reading fluency and their relations with reading comprehension. In a series of structural equation models with latent variables using data from 316 first-grade students, (a) silent and oral reading fluency were found to be related yet distinct forms of reading fluency, (b) silent reading fluency…
