Individuals with acquired phonological dyslexia experience difficulty associating written letters with their corresponding sounds, especially in pseudowords. Several studies have attempted to improve reading in this population by training letter-to-sound correspondence, general phonological skills, or a combination of these approaches; however,…

Purpose: This study explores the importance of production frequency during speech therapy to determine whether more practice of speech targets leads to increased performance within a treatment session, as well as to motor learning, in the form of generalization to untrained words. Method: Two children with childhood apraxia of speech were treated…

This article reviews several decades of the author's meta-analytic and experimental research on the conditions under which nonrandomized experiments can approximate the results from randomized experiments (REs). Several studies make clear that we can expect accurate effect estimates from the regression discontinuity design, though its statistical…

This study evaluated the effects of simulation training to teach functional community skills to four students with developmental disabilities in middle school. A multiple probe across participants and multiple probe across behaviors allowed for an evaluation of a functional relation between simulation and skill acquisition. Students learned how to…

A multiple probe design was used to assess the combined effects of video modeling, graduated guidance and community-based instruction for teaching children with autism how to protect themselves from the lures of strangers. Parental opinions were also assessed in the study. Three children with autism (aged 6 to 11 years) participated in the study.…

Under certain conditions, statistical evidence is more persuasive than anecdotal evidence in supporting a claim about the probability that a certain event will occur. In three experiments, it is shown that the type of argument is an important condition in this respect. If the evidence is part of an argument by generalization, statistical evidence…

This study was conducted to evaluate alternative analysis strategies for the meta-analysis method of reliability generalization when the reliability estimates are not statistically independent. Five approaches to dealing with the violation of independence were implemented: ignoring the violation and treating each observation as independent,…

A common way of discussing generalisation is to search for one conception--a monist view. Another approach is to create a dichotomy between quantitative and qualitative research, each having a single definition--a dualist perspective. A pluralist view is argued for here, i.e. the existence of several lines of reasoning, each of which can be…

A multiprobe, multiple baseline design was used to evaluate the effectiveness of persuasive writing strategy instruction. Six middle school students with emotional and behavioral disabilities (EBD) received two instructional phases of Self-Regulated Strategy Development (SRSD) instruction for writing persuasive essays over 33 days of intervention.…

This article focuses on the Incredible Years Teacher Classroom Management Training (IY TCM) intervention as an example of an evidence-based program that embeds coaching within its design. First, the core features of the IY TCM program are described. Second, the IY TCM coaching model and processes utilized to facilitate high fidelity of…

The models presented here posit a complex relationship between efficacy in student engagement and intent-to-leave that is mediated by in-class variables of instructional management, student behavior stressors, aspects of burnout, and job satisfaction. Using data collected from 631 teachers, analyses provided support for the two models that…

We report findings of research that deals with secondary students' interaction with a digital microworld, eXpresser. eXpresser is designed to support students in constructing general figural patterns of square tiles and expressing the algebraic rules that underlie them. Our focus is on the sense production that emerges as students use eXpresser.…

Scientific studies of child maltreatment victims' memory abilities and court experiences have important legal, psychological, and clinical implications. However, state-of-the-art research on child witnesses is often hindered by methodological challenges. In this paper, we address specific problems investigators may encounter when attempting such…

We examined associations between child inhibitory control, harsh parental discipline and externalizing problems in 120 4 year-old boys and girls in the US, China, and Japan. Individual differences in children's inhibitory control abilities, assessed using behavioral tasks and maternal ratings, were related to child externalizing problems reported…

This study with 213 South Korean college students (113 men) examined the cross-cultural generalizability of (a) the factor structure of the Frost Multidimensional Perfectionism Scale (F-MPS) and (b) the existence of adaptive perfectionists, maladaptive perfectionists, and nonperfectionists. A confirmatory factor analysis did not support the…
