Do acting out verbs with dolls and comparison learning between scenes boost toddlers' verb comprehension?

To better understand how toddlers integrate multiple learning strategies to acquire verbs, we compared sensorimotor recruitment and comparison learning because both strategies are thought to boost children's access to scene-level information. For sensorimotor recruitment, we tested having toddlers use dolls as agents and compared this strategy with having toddlers observe another person enact verbs with dolls. For comparison learning, we compared providing pairs of: (a) training scenes in which animate objects with similar body-shapes maintained agent/patient roles with (b) scenes in which objects with dissimilar body-shapes switched agent/patient roles. Only comparison learning boosted verb comprehension.

A Read-Aloud Storybook Selection System for Prereaders at the Preschool Language Level: A Pilot Study.

PURPOSE: Many well-accepted systems for determining difficulty level exist for books children read independently, but few are available for determining the wide range of difficulty levels of storybooks read aloud to preschoolers. Also, the available tools list book characteristics only on the basis of parents' or authors' opinions. We created an empirically derived difficulty-level system on the basis of 22 speech-language pathologists' (SLPs) judgments of specific storybooks used in preschooler read-alouds. METHOD: SLPs sorted 11 storybooks into ranked stacks on the basis of how difficult they thought the storybooks would be for preschoolers to understand when read aloud. SLPs described each stack globally as well as why they assigned each storybook to a particular stack. From transcriptions of the explanations, we derived a glossary of book characteristics using content analysis. We created a difficulty-level scale using a multivariate analysis technique that simultaneously analyzed book sorts and glossary terms. RESULTS: The book selection system includes a glossary of book characteristics, a 4-level difficulty scale, and exemplar books for each level. CONCLUSION: This empirically derived difficulty-level system created for storybooks read aloud to preschoolers represents a step toward filling a gap in the read-aloud literature.

Distinguishing between casual talk and academic talk beginning in the preschool years: an important consideration for speech-language pathologists.

PURPOSE: The need for speech-language pathologists (SLPs) to consider an academic talk (AT) register in addition to an everyday casual talk (CT) register of oral language with children beginning in the preschool years is presented, the AT and CT registers are distinguished in a comprehensive manner, ideas regarding AT language assessment are proposed, and suggestions for fostering children's skills with the AT register are offered. METHOD: Extant research and scholarship from a wide variety of disciplines are integrated and organized. RESULTS: The author discusses the role of the SLP in supporting AT skills beginning in the preschool years and the added risk of difficulties with the AT register for children with language impairment who are from diverse backgrounds. Two broad categories-social-interactive and cognitive-that give rise to linguistic features that differentiate between the CT and AT registers are deduced from extant scholarship. CONCLUSIONS: SLPs should consider children's competence with the AT register as they work to prepare preschoolers and older children for the language demands of school.

The effects of race and maternal education level on children's retells of the Renfrew Bus Story--North American Edition.

PURPOSE: The Renfrew Bus Story--North American Edition (RBS-NA; C. Glasgow & J. Cowley, 1994) is widely used in clinical and research settings to determine children's language abilities, although possible influences of race and maternal education on RBS-NA performance are unknown. The current study compared RBS-NA retells of 4 groups of children: African American (AA) children and European American (EA) children whose mothers had an education level of high school or less (≤ HS) and those whose mothers had an education level higher than high school (> HS). METHOD: Statistical tests were used to examine 172 kindergartners' story retells using raw scores for all 4 RBS-NA measures: (a) Information, (b) Sentence Length, (c) Complexity, and (d) Independence. RESULTS: A 2 × 2 analysis of variance (ANOVA) revealed main effects of maternal education and race for the Information score, with ≤ HS and AA children scoring lower. For measures not meeting ANOVA assumptions, 2 × 2 ANOVAs using ranked data indicated significant main effects of maternal education for Sentence Length, Complexity, and Independence measure, with ≤ HS children scoring lower within the AA group. CONCLUSION: There are systematic effects of maternal education and race on children's RBS-NA performance, which is important for both researchers and clinicians to take into account when using this instrument.

Historical perspectives on literacy in early childhood.

PURPOSE: To more fully understand current trends in preliteracy research, as well as controversies that continue to surround best teaching practices, it is essential to have an understanding of the historical evolution of ideas and practices relevant to preparing young children for learning to read. METHOD: Several interrelated historical movements relevant to placing current research and practices related to preliteracy development in context are reviewed. These ideas play out in the interrelated and changing ideas regarding the role of the family in children's literacy development, as well as in the appropriate curriculum for preschoolers. Both historical reviews and original documents pertinent to the various historical trends are used to provide the current synthesis. CONCLUSIONS: The roots of most current practices during, and controversies regarding, the preliteracy period of development can be traced to a variety of different historical events, as well as to prominent philosophers and educators. Familiarity with these events, philosophers, and educators provides the perspective needed to effectively evaluate new information and approaches that come to the forefront, or that are currently being practiced by different groups or in different settings.

Should we use telegraphic or grammatical input in the early stages of language development with children who have language impairments? A meta-analysis of the research and expert opinion.

PURPOSE: In working with children with language impairments, some clinical scholars and clinicians advocate using input that is simplified to the point of being ungrammatical (telegraphic input), while others advocate simplified but grammatical input. This article considers 2 types of external evidence on this topic. METHOD: First, a meta-analysis of relevant research, including intervention studies and processing studies, is reported. Next, 4 experts present their opinions. RESULTS: Children in the majority of the intervention studies showed no difference in language comprehension based on type of input, although 1 study with very few children favored telegraphic input for language production. In the processing studies, which measured immediate comprehension, children from clinical populations responded inconsistently when listening to the 2 types of input. Children who had typical language, however, favored grammatical input in their responses. Regarding the experts' opinions, 2 suggest that telegraphic input is sometimes warranted; 1, who previously indirectly promoted its occasional use, no longer believes it should be used; and 1 provides reasons why telegraphic input should not be used and may even be harmful. CONCLUSIONS: Empirical findings and expert views are summarized as ways of informing parents of the weak evidence base regarding the best type of input.

Fostering literal and inferential language skills in Head Start preschoolers with language impairment using scripted book-sharing discussions.

PURPOSE: Preschoolers with language impairment have difficulties with both literal and inferential language, both of which are critical to later reading comprehension. Because these children are known to be at risk for later reading comprehension difficulties, it is important to design and test interventions that foster both literal and inferential language skills. Using a randomized pretest-posttest control group design, we investigated whether an 8-week, one-on-one book-sharing intervention would improve both the literal and inferential language skills of Head Start preschoolers with language impairments. METHOD: Thirty children were randomly assigned to either a control group that received no intervention or to a treatment group that received twice-weekly 15-min sessions in which adults read books and asked both literal and inferential questions about the books using scripts that were embedded throughout the text. Treatment and control groups were compared using pre- and posttest scores on 2 measures of literal and 1 measure of inferential language skill. RESULTS: Significant group differences, and medium to large effect sizes, were found between pre- and posttest scores for all 3 measures. CONCLUSIONS: These findings suggest that book sharing with embedded questions that target both literal and inferential language skills can result in gains on both types of language in this population. Future studies with larger number of children are needed to corroborate these findings.
