In 3 experiments, I investigated the role of verbal behavior development in reading and spelling sight words. I evaluated effects of different interventions for reading and spelling sight words and establishing the transformation of stimulus function across word reading and spelling. In Experiment 1, I evaluated the effects of 3 interventions on…

This study compared 2 units of analysis for assessing acquisition mastery during sight word instruction for 3 participants. The unit of analysis refers to the specific performances that criteria are applied to, either sets of stimuli or individual operants. In the Set Analysis condition, we applied the acquisition-performance criterion to the…

Dyslexia is a reading disability affecting a large number of people worldwide. People with dyslexia have at least normal levels of intelligence, yet they nevertheless have significant difficulties with reading. Dyslexia is known to have genetic causes; however, some researchers believe that there are also environmental factors at play.…

We compared the effects of different "mastery" criteria and doses on the acquisition and maintenance of sight words for 4 second graders with and without disabilities. First, we replicated Set Analysis and Operant Analysis conditions where participants were taught sight words in 20-trial (4 operants, 5 opportunities) sessions.…

Instructors assess the acquisition of new skills by delivering blocks of trials containing multiple operants. Mastery is evaluated as percentage correct across all operants in the block. The purpose of the current study was to investigate this traditional mastery criterion arrangement compared to an analysis of mastery at the level of individual…

High frequency words, commonly referred to as sight words, are often a focus of emergent reading instruction. Instructional practices abound that require emergent readers to memorize the spelling and pronunciation of the words without drawing attention to grapheme-phoneme correspondences (GPCs) in the words. These approaches ignore a critical…

Understanding the early literacy abilities of children who use augmentative and alternative communication (AAC) is essential for designing and testing methods of reading intervention focused on printed orthography. School-based professionals need assessments that measure word reading skills of students with heterogenous speech and physical…

In elementary school, an important goal of reading instruction is to enable children to read most words automatically by sight so that they can focus on learning from and enjoying what they are reading. But becoming a strong reader takes several years. Parents and caregivers need to know if a child is making good progress in learning to read.…

Although many studies have shown the efficacy of using flashcard interventions to increase sight-word reading, very few have investigated ways to increase sight-phrase reading. In the current study, a concurrent multiple-baseline across students design was used to examine the effects of a tablet-based flashcard intervention on the acquisition of…

This study measured the effectiveness of sight word practice using flashcards and the growth results were compared based on presentation formats when administered to a group of second grade students. The data were later disaggregated to compare the success rates of each platform among three different subgroups within the test population, based on…

The purpose of this research was to determine the effectiveness of goal setting as a motivator for kindergarten students in learning grade-level sight words. This study was conducted over a 6-week period in two Midwestern kindergarten classrooms. The participants in the experimental group were trained in self-setting goals and participated in…

The Strategic Incremental Rehearsal (SIR) intervention, a modified version of Incremental Rehearsal, is an efficient flashcard procedure that has demonstrated effectiveness on sight word acquisition for children who exhibit reading difficulties. However, to date, the procedure has not been evaluated with children identified with a reading…

Looking at Cape Henlopen School District as a whole, most students within the district are proficient in reading. When looking at data for young adults (18-22) with autism and other severe disabilities in the Sussex Consortium Life Skills Program, students were not proficient in reading. They could not read functional words within context. This…

The process of learning to read is more difficult for English language learners (ELLs) because they are often learning a new language as they are trying to learn to read. Learning irregular/high-frequency words (sight words) may be especially challenging for ELL students. Limited research exists on the effects of interventions designed to help ELL…

Discrimination of reversible mirrored letters (e.g., d and b) poses a challenge when learning to read as it requires overcoming "mirror invariance," an evolutionary-old perceptual tendency of processing mirror images as equivalent. The present study investigated "when," in reading development, mirror-image discrimination…
