Beyond the established difficulties of individuals with dyslexia in word recognition and spelling, it remains unclear how severe their difficulties in comprehension are. To examine this, we performed a meta-analytic review. A random-effects model analysis of data from 76 studies revealed a large deficit in reading comprehension in individuals with…

Researchers disagree about the value of controlling the decodability of texts for students with reading difficulty, specifically what type of text they should read: "decodable texts" (words limited to taught patterns), "nondecodable" texts (those not limited by instruction), or "both." We analyzed the effects of…

The effectiveness of incorporating independent reading practice in schools has long been a subject of uncertainty. To shed light on this ongoing debate, this meta-analysis seeks to investigate the impact of in-school independent reading on three crucial measures--attitudes toward reading, word recognition, and comprehension--focusing on K-10…

As they develop into mature speakers of their native language, infants must not only learn words but also the sounds that make up those words. To do so, they must strike a balance between accepting speaker-dependent variation (e.g., mood, voice, accent) but appropriately rejecting variation when it (potentially) changes a word's meaning (e.g., cat…

Associative word learning, the ability to pair a concept to a word, is an essential mechanism for early language development. One common method by which researchers measure this ability is the Switch task (Werker, Cohen, Lloyd, Casasola, & Stager, 1998), wherein infants are habituated to 2 word-object pairings and then tested on their ability…

In four experiments, we investigated the impact of letter case (lower case vs. UPPER CASE) on the processing of sequences of written words. Experiment 1 used the rapid parallel visual presentation (RPVP) paradigm with postcued identification of one word in a five-word sequence. The sequence could be grammatically correct (e.g., "the boy likes…

Inequality in reading outcomes is perhaps the single greatest social justice issue faced by school psychologists, and school psychologists need a better understanding of reading theory and its application to intervention to better combat the important issue. The present study examined the active view of reading (AVR; Duke & Cartwright, 2021),…

In this study, we examined the effects of word and character frequency across three commonly used word-identification tasks (lexical decision, naming, and sentence reading) using the same set of two-character target words (N = 60) and participants (N = 82). Facilitatory effects of word frequency were observed across all three tasks. The…

We meta-analyzed the effectiveness of incidental second language word learning from spoken input. Our sample contained 105 effect sizes from 32 primary studies employing meaning-focused word-learning activities with 1,964 participants with typical cognitive functioning. The random-effects meta-analysis yielded a mean effect size of g = 1.05,…

A single-subject alternating treatment design was used to investigate the extent to which a specialized dyslexia font, OpenDyslexic, impacted reading rate or accuracy compared to two commonly used fonts when used with elementary students identified as having dyslexia. OpenDyslexic was compared to Arial and Times New Roman in three reading tasks:…

Background: Oral language skills are a critical foundation for literacy and more generally for educational success. The current study shows that oral language skills can be improved by providing suitable additional help to children with language difficulties in the early stages of formal education. Methods: We conducted a randomized controlled…

This pilot project investigated the effects of ABRACADABRA (ABRA), a web-based literacy program developed by the Centre for the Study of Learning and Performance (CSLP) at Concordia University, on primary school children in Hong Kong. A total of 125 Primary 2 students participated in a 14-week long study. Five classes were randomly assigned to…
