Like all psychoeducational batteries, the Wechsler Individual Achievement Test, Fourth Edition (WIAT-4) requires independent investigation and analysis. The publisher provides multiple theories to support interpretation of its reading measures. At the word reading level, the battery includes a new Phonemic Proficiency subtest that the publisher…

Fluent word recognition is an essential component of skilled reading, yet most children with reading difficulty have impaired word recognition. We developed and evaluated a web app, WordDriver, delivered via teletherapy, which targets phonological recoding to support orthographic learning and efficient word recognition. Participants were five…

Oral language and early literacy skills are theorized to provide the foundation for reading acquisition. To understand these relations, methods are needed that depict dynamic skill development in the context of reading acquisition. We modeled contributions of school-entry skills and early skill trajectories to later reading with 105 5-year-old…

Simple mean differences summarized in meta-analyses do not always adequately describe sex similarities and differences. We investigated sex similarities and differences in academic achievement test scores during childhood and adolescence multiple ways based on composite and subtest scores from the Kaufman Test of Educational Achievement (Third…

This study analyzes the relationship between phonemic proficiency and orthographic learning in first and second-grade students. It is established in the empirical literature that phonemic skills play a crucial role in word-level reading. What is not thoroughly understood is why some children learn and remember words more efficiently than others.…

Reading comprehension assessments often vary from one measure to another related to the response format required, passage length and other variables. Yet, these measures purport to assess the same skill of reading comprehension, and they are often used interchangeably. Over the last decade some reading researchers have raised concerns that the…

Dyslexia, which affects between 5% and 18% of Americans, is caused by difficulties with phonological processing. This study investigates the impact of an online intervention which remediates phonological processing deficits on functional reading skills such as accuracy, fluency, and comprehension. It also investigates changes to student…

Purpose: We conducted a randomized control trial of an instructional program, SRSD Plus, which integrates reading for writing to inform, writing, oral language, spelling and handwriting for students in Grades 1 and 2. Method: A total of 10 teachers and their 248 students in Grade 1 (n = 121) and Grade 2 (n = 127) in the southwestern part of the US…

In order to make appropriate educational recommendations, psychologists must understand how cognitive test scores influence specific academic outcomes for students of different ability levels. We used data from the WISC-V and WIAT-III (N = 181) to examine which WISC-V Index scores predicted children's specific and broad academic skills and if…

This study determines the effectiveness of a non-digital picture concept programme to treat cognitive deficits in pupils with dyslexia. Using a sample of 38 primary two pupils (aged 7-9 years) in Ebonyi State, Nigeria, a Picture Concept Activity and the traditional method of repetitive passage drill were administered for eight weeks and results…

The purpose of this study was to analyze published decoding tests, at the item level, to determine what decoding skills and discrete letter-patterns are assessed, and identify potential instructional implications of these measures. Twenty published word list decoding tests, either used in research or within a Multi-Tiered Systems of Supports…

How prevalent is dyslexia? A definitive answer to this question has been elusive because of the continuous distribution of reading performance and predictors of dyslexia and because of the heterogeneous nature of samples of poor readers. Samples of poor readers are a mixture of individuals whose reading is consistent with or expected based on…

The purpose of this study was to examine whether group-based differences exist in word- and text-level reading in a clinical sample of students with dyslexia, and to shed light on the cognitive processes supporting these essential skills. Second- through seventh-grade students were administered a battery of standardized measures of cognitive…

We attempted to strengthen an evidence-based, peer-mediated, first-grade reading program (First Grade Peer-Assisted Learning Strategies [PALS]) by modestly revising its content and adding a repeated-reading (RR) component. In a cluster-randomized trial, we conducted a component analysis of the revised program by creating two versions of it.…

A data-driven, transdiagnostic approach was used to identify the cognitive dimensions linked with learning in a mixed group of 805 children aged 5 to 18 years recognized as having problems in attention, learning, and memory by a health or education practitioner. Assessments included phonological processing; information processing speed; short-term…
