The purpose of this experimental study was to examine the contribution of phoneme awareness training and orthography to the learning of new vocabulary words by partial alphabetic phase readers. Hypotheses included: Preschoolers taught to phonemically segment words with letters would outperform those trained without letters on an invented spelling…

In this study, we aimed to evaluate further the functioning and structuring of the semantic system in autism spectrum disorders (ASD). We analyzed the performance of 19 high-functioning young adults with ASD and a group of 20 age-, verbal IQ- and education-matched individuals with the Proactive Interference (PI) Paradigm to evaluate semantic…

We evaluated the emergence of untaught second-language skills following directly taught listener and intraverbal responses. Three preschool children were taught first-language (English) listener responses (e.g., "Point to the horse") and second-language (Welsh) intraverbal responses (e.g., "What is horse in Welsh?" [ceffyl]).…

Early and intensive behavioral intervention has been shown to result in favorable outcomes for children with autism spectrum disorder. Procedures and practices based on and influenced by B. F. Skinner's Verbal Behavior (VB) have been increasingly integrated into EIBI curricula in recent years. In this article, I give an overview of some basic…

The literature concerning sexuality in autism spectrum disorders (ASDs) is limited regarding inappropriate sexual behaviours and paraphilias and its relation to age, verbal ability, symptom severity, intellectual ability, or adaptive functioning. A cohort of 184 adolescents and young adults (ages 15-39 years) with ASD diagnosed in childhood,…

This study examines students' exposure to print, vocabulary and decoding as predictors of spelling skills. Participants were 42 college students (Mean age 22.5, SD = 7.87; 31 females and 11 males). Hierarchical regression analyses showed that most of the variance in spelling was explained by vocabulary knowledge. When vocabulary was entered first…

Background: Problems with pragmatic aspects of language are well attested in individuals on the autism spectrum. It remains unclear, however, whether figurative language skills improve with language status and whether problems in figurative language are no longer present in highly verbal individuals with autism. Aims: To investigate whether highly…

Languages differ in their preferences for particular intensifying constructions. While intensifying adjectival compounds (IACs) (e.g. "ijskoud, ice-cold") are productively used to express intensification in Dutch and English, in French this construction is hardly productive. Consequently, French-speaking learners may encounter…

Research Findings: Optimal sleep is important for children's learning and development. "Sleep disordered breathing" (SDB) refers to a spectrum of conditions from simple snoring to obstructive sleep apnea that is common in childhood and interrupts sleep. We examined pathways between SDB and academic performance of children (N = 163, M…

Introduction: Excessive alcohol consumption is the most widespread toxic habit in the world, and a particular problem among young people for whom alcohol is part of their recreational habits. The start of university studies coincides with adulthood when alcohol becomes easily available and used as a tool to deal with new stressors. It has been…

Although extensive research exists on vocabulary instruction during book reading in preschool classroom, comparatively little research has been conducted on vocabulary exposure in classroom play contexts and child vocabulary outcomes. The purpose of this study was to examine Head Start teacher and child vocabulary use in dyadic play sessions and…

In South Africa under apartheid, higher education was unavailable to a large segment of the population. Many who enrol for an undergraduate degree today are thus mature students or 'adult learners' 25 years or older who are in full-time employment. Since these students learn differently from their younger peers, institutions need to know what…

Children from diverse backgrounds are able to learn new words from educational media. However, learning is often partial and fragile, leaving much room for uncovering strategies that can increase the efficacy of educational media in supporting children's vocabulary knowledge. The present study investigated one such strategy--repeated viewing of…

This paper focuses on the influence of socio-economic risk factors and different aspects of the home learning environment in early childhood on children's language competencies (vocabulary and grammar skills). The assumption is that children with more risk factors have lower competencies, but the home learning environment (measured by everyday…

The provision of reinforcement to increase desired behaviors is a crucial element of behavior analytic intervention for individuals diagnosed with autism spectrum disorder (ASD). Formal preference assessments, like the multiple stimulus without replacement procedure (MSWO), are often used to determine reinforcers used during intervention. While…
