Purpose: This study compared performance on the Syllable Repetition Task (SRT) by preschoolers with diverse speech and language abilities to identify underlying impairments in speech processes. Method: Three groups of 13 children ages 4 and 5 years with (a) typically developing (TD) speech and language, (b) speech sound disorder (SSD), and (c)…

According to prediction-based learning theories, erroneous predictions support learning. However, empirical evidence for a relation between prediction error and children's language learning is currently lacking. Here we investigated whether and how prediction errors influence children's learning of novel words. We hypothesized that word learning…

Purpose: This study examines the response patterns of 278 Spanish-English dual language learners (DLLs) on a standardized test of receptive English vocabulary. Method: Investigators analyzed responses to 131 items on the Peabody Picture Vocabulary Test--Fourth Edition (Dunn & Dunn, 2007) focusing on differential accuracy on items influenced by…

Background: It is already known that preschool-age children who stutter (CWS) tend to stutter on function words at the beginning of sentences. It is also known that phonological errors potentially resulting in part-word repetitions tend to occur on content words. However, the precise relation between word class and repetition type in preschool-age…

The aim of this longitudinal study was to examine spelling acquisition in French children with developmental language disorder (DLD) over a school year. Through a fine-grained spelling error analysis, we investigated whether spelling profiles could be established in the DLD population. This study comprised three groups: a typically developing (TD)…

We propose that attraction errors in agreement production (e.g., the key to the cabinets are missing) are related to two components of executive control: working memory and inhibitory control. We tested 138 children aged 10 to 12, an age when children are expected to produce high rates of errors. To increase the potential of individual variation…

This study investigated differences in the phonological knowledge and reading skill of deaf adults using three experimental conditions that tested sensitivity to syllables, rhyme, and phonemes. Analysis of response latencies and accuracy in the three awareness tasks demonstrated that skilled deaf readers had superior phonological awareness skill…

We statistically examined the oral reading fluency of 295 adults with low literacy by analyzing total words read per minute and word error rates. We identified four fluency-ability groupings based on standardized assessments of reading-related skills (phonemic awareness, word recognition, vocabulary, comprehension, and general ability). Our…

This report is a review of reliability data on the PPVT obtained from 32 research studies published between 1965 and 1974. For average children in the elementary grades, and for retarded people of all ages, PPVT scores remained relatively stable over time and there was close equivalence between alternate forms. (Author)
