Purpose: This study evaluated the effects of an automated, small-group intervention designed to teach preschoolers challenging vocabulary words. Previous studies have provided evidence of efficacy. In this study, we evaluated the effects of the program after doubling the number of words taught from 2 to 4 words per book. Method: Seventeen…

Purpose: This experiment investigated the effects of a book-sharing intervention implemented in coparenting homes on the conversations of preschoolers with their parents. Method: A multiple baseline design across behaviors was used to evaluate the effects of embedding decontextualized language utterances during book-sharing delivered by four…

Purpose: This article describes the iterative development of a home review program designed to augment vocabulary instruction for young children (ages 4 and 5 years) occurring at school through the use of a home review component. Method: A pilot study followed by two experiments used adapted alternating treatment designs to compare the learning of…

Matrix training is a systematic teaching approach that can facilitate generalized language. Specific responses are taught that result in the emergence of untrained responses. This type of training facilitates the use of generalized language in children with autism spectrum disorder (ASD). This study used a matrix training procedure with a toddler…

Purpose: This study investigated cumulative effects of language learning, specifically whether prior vocabulary knowledge or special education status moderated the effects of academic vocabulary instruction in high-poverty schools. Method: Effects of a supplemental intervention targeting academic vocabulary in first through third grades were…

It is well established that oral language skills in preschool, including vocabulary and comprehension, predict later reading proficiency and that substantial differences in oral language skills exist when children enter school. Although explicit instruction embedded in storybooks is a promising intervention approach, high-fidelity implementation…

Preschool experience plays a role in children's development. However, for programs with language and early literacy goals, the question remains whether preschool instructional experiences are sufficiently effective to achieve these goals for all children. In a multisite study, the authors conducted a process-product description of preschool…

Purpose: This study examined whether English-only vocabulary instruction or English vocabulary instruction enhanced with Spanish bridging produced greater word learning in young Spanish-speaking children learning English during a storybook reading intervention while considering individual language characteristics. Method: Twenty-two…

Research on the environmental conditions promoting generative language learning is reviewed. Recombinative generalization is introduced as a principle of stimulus control that enables individuals to express and to comprehend novel utterances. Alternative matrix-training procedures should be considered in attempts to optimize the development of…

A simultaneous treatments design was used to compare effects of modeling and corrected practice on generative language acquisition of six preschoolers. New syntactic forms used to describe agent-action-object stimuli were taught concurrently. All six children learned both new syntactic forms. Corrected practice produced a faster rate of learning.…

Two experiments involving four and seven normal children four- to eight-years-old examined processes responsible for generative language acquisition and conditions likely to facilitate recombinative generalization. All children learned new syntactic rules to generate three word utterances, regardless of the orderings of agent, action, and object…

Matrix training strategies were used to teach three severely mentally retarded children syntactic rules for combining known words into two- and three-word utterances. Training only a limited number of responses was sufficient to promote recombinative generalization in the trained modality and transfer to untrained responses in the opposite…
