Measuring the Effects of Cognitive Capacity on Sentence Comprehension: Evidence From Elementary School-Age Children

Magimairaj, B.M., Nagaraj, N.K., & Gillam, R.B. (2024). Measuring the effects of cognitive capacity on sentence comprehension: Evidence from elementary school-age children. Journal of Speech, Language, and Hearing Research, 67(10), 3778-3793.

Sentence comprehension in children is a complex process involving various cognitive mechanisms beyond vocabulary and syntax. One critical aspect of this process is working memory (WM) capacity, which refers to the ability to hold and manipulate information in the mind over short periods. Additionally, retrieval from long-term memory (LTM) plays a significant role in how children understand sentences. This study aimed to explore these cognitive predictors of sentence comprehension in elementary school-age children, focusing on how WM and LTM interact during comprehension tasks.

In this study, children with typical development or Developmental Language Disorder (DLD) completed a sentence comprehension task by choosing a picture corresponding to a spoken sentence. Comprehension of adjectives included in the sentences either was or was not required to choose the right picture creating sentences of high or low cognitive load, respectively. Children also completed working memory tasks involving digit recall and a long-term memory task requiring categorizing or judgement of meaning relationships. The DLD group had lower comprehension accuracy, particularly when processing sentences requiring higher cognitive effort. As well, working memory was found to be a stronger predictor of comprehension accuracy than long-term memory. 

The findings suggest that children with DLD may struggle more with the demands placed on their WM capacity when interpreting complex sentences.

Supporting literacy development in kindergarten through teacher-facilitated play

Pyle, A., Wickstrom, H., Gross, O., & Kraszewski, E. (2024). Supporting literacy development in kindergarten through teacher-facilitated play. Journal of Early Childhood Research, 22(3), 428–441. https://doi.org/10.1177/1476718X231221363

Play-based learning is essential for supporting children’s learning during the early years. In fact, playful pedagogy is mandated as part of the current Ontario kindergarten curriculum. While it may sound simple to teach language and literacy skills in play, educators have expressed challenges related to (lack of) knowledge and confidence in knowing how and when to teach goals during play in a balanced way. The current study seeks to understand how different types of play may support different types of literacy skills. 

This study involved observing 30 kindergarten classrooms in Ontario. Observations were coded for the type of play observed and literacy skills targeted during play.

Play was defined as:

• Free play – Child-directed play with minimal educator involvement
• Teacher-direct play – Teacher-led activities with direct instruction and explicit steps that children follow
• Guided play – Educators create a context to focus on specific learning goals, while children direct play. Guided play is a combination of free play and teacher-directed play

Literacy skills were defined as:

• Alphabetics – Alphabet knowledge and decoding skills
• Fluency – Reading with speed and accuracy
• Comprehension – Understanding text and vocabulary
• Text conventions – Playing with books; book handling 
• Writing – Games with writing
• Oral language – Form (e.g., structure, grammar) and use (non-literal language) of language as well as storytelling skills

Results found that different types of play lend themselves well to targeting different types of literacy skills. Free play was the most common type of play in Ontario kindergarten classrooms. Free play targeted skills like text conventions and oral language. Teacher-directed play was the second most common form of play, targeting alphabetics, fluency, and writing skills. While guided play was the least common, all literacy skills were targeted during guided play. The authors advocate for enhancing guided play practice to support literacy skills in a more comprehensive way. 

We are also interested in the potential of guided play to support the full spectrum of oral language skills including grammar, vocabulary, sentence structure and length, and verbal reasoning. Another consideration is that talk during play may be good for good talkers, but those with weak oral language skills (English language learners, developmental language disorders) would require intentional instruction.

A meta-analytic review of the relations between motivation and reading achievement for K–12 students

Toste, J. R., Didion, L., Peng, P., Filderman, M. J., & McClelland, A. M. (2020). A meta-analytic review of the relations between motivation and reading achievement for K–12 students. Review of Educational Research, 90(3), 420-456.

Developing proficiency in reading is crucial to success for students at school and beyond. Growing evidence indicates that motivation plays a significant role in predicting reading performance over and above what is explained by cognitive and academic skills. Consequently, increasing knowledge on the relations between motivation constructs and reading has the potential to improve understanding of reading development and achievement. It can also inform investigations into how motivation might be applied to reading intervention.

In this meta-analysis, the authors sought to build on the previous literature by investigating the relations between motivational processes and reading in students across the school years (kindergarten through to grade 12). One of the issues identified was that motivation is complex and multidimensional, and research has been based on a range of theories which can be overlapping. This has led to inconsistency in the terminology and definitions used by researchers, creating challenges in understanding in the area. The authors used Conradi et al.’s (2014) hierarchy for categorizing and defining motivation constructs to, firstly, investigate the relationship between ‘a broad construct’ of motivation and reading in the literature. This hierarchy defines three constructs (goal orientation, beliefs, and disposition), with subconstructs under each of these. Intrinsic motivation was also included in the analysis. The authors then explored other potential moderators of interest -

(a) reading domain (code vs meaning focused)

(b) reading ability (typically developing vs students with learning disabilities or at risk)

(c) grade (elementary vs secondary)

Interactions between these moderators was examined, along with the influence of year of publication and motivation measure type (domain specific vs general). Directionality between motivation and reading in longitudinal investigations was also examined.

The search of the literature identified 132 peer-reviewed articles with 185 independent samples. Results indicated a significant, moderate relation between motivation and reading (r= .22, p< .001) with beliefs and disposition showing a stronger relation to reading than goal orientation. The authors propose that this suggests that motivation constructs can be different for different students, rather than a simple dichotomy of students being motivated or unmotivated.

No other significant interactions were found between the three motivation constructs, nor with the other moderating factors (reading domain, reading ability, grade) or between the moderating factors themselves. The authors found it surprising that the findings of the meta-analysis did not support the literature or the authors’ hypotheses that (a) struggling readers would have lower motivation than typically developing students, and (b) motivation decreases as students get older. The possible reasons for this are discussed. The longitudinal studies identified in the sample, all with typically developing students, suggested earlier reading is a stronger predictor of later motivation than motivation is of reading, reinforcing the importance of early reading instruction and intervention.

Lexical-semantic organization as measured by repeated word association in children who are deaf and hard of hearing who use spoken language

Rush et al. (2023). Lexical-semantic organization as measured by repeated word association in children who are deaf and hard of hearing who use spoken language. JSLHR, 66, 3925-39.

Word knowledge is usually measured in terms of quantity, that is, the number of words a child knows. However, the way a child links and stores words for retrieval is another important component of word knowledge called lexical-semantic organization. There are 3 subprocesses involved in word learning: (1) Triggering – recognition that a word is new and must be learned, (2) configuration – recognizing and mapping a phonological (speech sound) and semantic (meaning-based) representation of a new word to what it refers to, and (3) engagement – the necessary interaction between a new word and the child’s existing word knowledge to facilitate organization of stored words. Perhaps unsurprisingly, children who are deaf and hard of hearing (DHH) tend to know fewer words than their hearing peers. Available research suggests that children who are DHH may have difficulty with the triggering and engagement subprocesses of word learning, although research addressing configuration is limited. One task used to study lexical-semantic organization is a repeated word association task. In this task, an individual prompt (e.g., the word turtle) is repeated multiple times and an individual is expected to provide a different single word response each time. Responses can be analyzed in terms of their relation to the target, for example, whether responses are semantically related, clang (share sounds or rhyme with the target word), or error responses. With development, hearing children typically provide more semantically related response.

In this study, kindergarten and grade 1 children who were typical hearing, wearing hearing aids, or with cochlear implants completed a repeated word association measure including 24 stimuli words (12 nouns, 12 verbs, included in text). Each word was presented 3 different times and the child was asked to verbally respond with the first word that comes to mind but to tell a new word each time they heard the same word. No differences in responses were noted between the hearing aid and cochlear implant groups, and so these groups were collapsed for further analysis. Results indicated a developmental increase in semantically related responses to target words regardless of hearing status. The younger DHH group produced more errors and when those errors were not semantically related, they produced more errors that were not clearly in the semantic network of the target word. The authors argued that this result could suggest that young children who are DHH may not organize their words using the most efficient strategies when learning new words. Over time, however, children with DHH showed similar lexical-semantic organization as typically hearing peers.

Measuring lexical-semantic organization may provide important information about a child’s lexical organization and flexible use of words. This information could help to understand a child’s word knowledge in more depth.

Dynamic Assessment of Narrative Skills for Identifying Developmental Language Disorder in Monolingual and Bilingual French-Speaking Children

Hadjadj, O., Kehoe, M., & Delage, H. (2024). Dynamic assessment of narrative skills for identifying developmental language disorder in monolingual and bilingual French-speaking children. Language, Speech & Hearing Services in Schools, 55(1), 130–151. https://doi.org/10.1044/2023_LSHSS-23-00054

Narratives are useful for assessing language skills in children, covering various domains like vocabulary and grammar. Typically, kids start storytelling with basic plots by age 5 and progress to more complex narratives by age 9. Children with language disorders struggle with both the structure (macrostructure) and details of stories (microstructure). While it is simpler to assess monolingual children for language disorders, bilingual children often are misdiagnosed due to less accurate assessment tools. In bilingual children, exposure time to each language along with age of learning second language are crucial when determining the storytelling abilities, with those exposed to a language later showing weaker language skills, resembling monolingual children with language disorders. Assessing bilingual children in all their languages is crucial to avoid misdiagnosis, but it's often challenging due to language diversity. Various tools, like parental questionnaires and language samples, can help evaluate bilingual children's language skills effectively. Dynamic assessment evaluates children's learning potential rather than static knowledge. It's suggested that children with language disorders have lower learning potential. DA involves teaching phases to improve performance between pre-and post-tests, aiding diagnosis accuracy. Because of its unbiased nature, this study used DA to assess various linguistic skills, including narratives, especially beneficial for diagnosing language disorders in bilingual children.

The main goal of this study was to investigate the effectiveness of Dynamic Assessment in distinguishing DLD and typical language development in French-speaking monolingual and bilingual children. Children (6-11 years old) were given a storytelling task before learning about story elements, then tested again. The test involved 12 questions: 8 focused on story grammar elements (macro-structure) and 4 focused on connectors (microstructure). Results showed no differences in storytelling ability between monolingual and bilingual children on macrostructure or microstructure elements. Children with (DLD) had lower scores than typically developing (TD) children, especially in microstructure elements.

This study provides further evidence that dynamic assessment can be useful in assessing the language abilities of bilingual children. The greater difficulty with story microstructure for children with DLD may indicate the need for tailored teaching methods.

Relations between teacher talk characteristics and child language in spoken-language deaf and hard-of-hearing classrooms

Duncan, M.K., & Lederberg, A.R. (2018). Relations between teacher talk characteristics and child language in spoken-language deaf and hard-of-hearing classrooms. Journal of Speech, Language, and Hearing Research, 61, 2977-2995. https://doi.org/10.1044/2018_JSLHR-L-17-0475

Children with hearing loss have difficulty learning spoken language. This impacts their literacy (reading and writing) skills as well. These children frequently have difficulty learning vocabulary simply by hearing words used, which is the way hearing children often learn new words. Children with hearing loss also have difficulty with syntax (putting words together to form sentences), likely due to the difficulties hearing key word endings or morphemes. Hearing impaired children perform significantly lower than their hearing peers on measures of both vocabulary and morphosyntax.

Duncan and Lederberg explain that past research has shown that certain aspects of adult language use can impact language development in hearing children. Interventions have been developed for hearing children employing these features of adult language, in particular through the use of certain characteristics of teacher talk. These teacher talk characteristics include:

1. Reformulation: repeating and expanding the child’s statement, modelling more adult-like language
2. Language elicitations: invitations to the child to respond with a single word or a short list of possible responses (closed elicitations), or to respond with longer or more complex responses (open-ended elicitations)
3. Explicit vocabulary instruction: the teacher provides a child-friendly definition and connects this new word to the child’s existing knowledge
4. Explicit grammar instruction: the explicit provision of grammar instruction
5. Wait time: allowing approximately 3 seconds after a language elicitation (e.g., a question) for the student to provide a response (allowing time to think about and form a higher-quality response)

While some research had been done on the impacts of parental language input and language development in hearing impaired children, little research has addressed the impacts of teacher language input for children with hearing loss. In this study, the authors addressed this gap, and did so with two goals. The first was to examine the characteristics of teacher talk being used in spoken language classrooms with hearing impaired children. The second was to determine the extent to which teacher talk relates to language gains for hearing impaired children in vocabulary and morphosyntax over a school year.

The authors examined the language (vocabulary and morphosyntax) scores of 68 hearing impaired children in kindergarten, grade one, and grade two. These students were from 25 classrooms in which spoken English was used exclusively. Language scores were collected in the fall and spring terms of the same school year. Teacher talk was observed, transcribed, and coded (for each of the 5 teacher talk characteristics) for a 20 minute period during the winter term.

When examining the characteristics of teacher talk used in the classrooms with hearing impaired students, they found that the most frequent of the teacher talk characteristics was the use of closed language elicitations. Open-ended language elicitations were frequently used as well, but to a lesser degree. While imitating the students’ statements verbatim was rare, reformulation of their statements was quite common. Use of explicit vocabulary instruction varied between teachers, with some using it once every two minutes, and others using it only a couple of times or not at all within the observation window. Wait time was not frequently observed, but this may have been due to students responding immediately. Explicit grammar instruction was rare.

When determining the impact of teacher talk characteristics on spoken language development of hearing impaired students across the school year, the authors found that greater use of reformulation and explicit vocabulary instruction were predictors of gains in vocabulary, and that use of explicit vocabulary instruction was a predictor of gains in morphosyntax.

The implications of this study are that language input from classroom teachers has the ability to promote language development in their students with hearing impairment. The use of certain characteristics of teacher talk can benefit hearing impaired students’ development of vocabulary and morphosyntax (in particular, the use of reformulations to support vocabulary gains, and explicit vocabulary instruction to support both vocabulary and morphosyntax gains). Teacher training programs could be designed to support teachers in the development of skills in these areas.

Nonverbal executive functioning in relation to vocabulary and morphosyntax in preschool children with and without developmental language disorder

Everaert et al. (2023) Nonverbal executive functioning in relation to vocabulary and morphosyntax in preschool children with and without developmental language disorder. JSLHR, 66, 3954-73.

Children with Developmental Language Disorder (DLD) have a persistent language difficulty that has a significant impact on school learning and everyday interactions. Executive functions are brain-based processes that allow us to create and sustain action towards goals while acting insightfully with others. Three cognitive resources support executive functions including the ability to update information held in mind or working memory, the ability to inhibit unnecessary information which, along with working memory, allows for selective attention, and cognitive flexibility, or the ability to put things together in unique ways. There are well-recognized links between executive functions and language learning. For example, working memory can support holding novel phonological forms in mind so that new vocabulary can be learned. In addition, putting words to the steps you need to complete helps you achieve goals. Given this link, there has been interest in examining executive functions in children with DLD.

One challenge with examining executive functions in children with DLD is that many executive functions tasks involve language. Indeed, systematic reviews has reported that children with DLD differ substantially from their typically developing peers when compared on verbally-loaded executive function tasks. The group difference, however, while reliable, is considerably smaller when the groups are compared on nonverbal function tasks such as recalling the sequence of indicated blocks.

This study examined the relationship between language (vocabulary; morphosyntax) and nonverbal executive function measures in 3-6 year old children with and without DLD. The children with DLD scored significantly lower than the typically developing group on all four executive function measures. An executive function factor was found to add significant predictive value to morphosyntax but not vocabulary performance in children with DLD. For typically developing children, executive functions predicted both vocabulary and morphosyntax. Diagnosis (DLD or not) was not a significant moderator of these relationships.

These results highlight the importance of using strategies to scaffold executive functions when providing language-based interventions with a high verbal load such as sentence-level activities. Strategies might include repeating information, providing visual supports, and breaking the task into smaller steps.

Playful punctuation in primary children’s narrative writing

Burrell, A., & Beard, R. (2022). Playful punctuation in primary children’s narrative writing. Research Papers in Education, 1-28. https://doi.org/10.1080/02671522.2022.2125053

Language play has been defined as any use of language that is creative and unusual. This article focused on language play through punctuation. This study investigated children's use of playful punctuation in narrative writing. The data were derived from a previous study focused on writing development in the 9–11 year olds and identified three attainment sub-groups: (i) the highest-attaining children in Year 6, (ii) children with the lowest scores in both Year 6 and Year 5, and (iii) children with the most significant increase in attainment between Year 5 and Year 6. The analysis examined the purpose and organization, grammar, vocabulary, style, punctuation, spelling, and handwriting aspects of writing. The analysis of 71 stories revealed diverse playful punctuation, with notable usage of quotation marks, exclamation marks, and question marks, while other elements like asterisks and interrobangs were used less frequently. Clear variations were observed among attainment groups in the content and extent of playful punctuation. The results suggest that narrative writing provides opportunities for creative and playful punctuation use by 10–11 year-olds, prompting further investigation into such linguistic play. The study also noted variations in punctuation use among individual children, highlighting stylistic choices. Some children favored certain punctuation marks, such as dashes or exclamation marks, to emphasize specific narrative effects. Additionally, the study observed unconventional uses of punctuation, like elongated ellipses (the use of several full stops together, often used to express hesitation) and the interrobang (the use of exclamation mark and a question mark together), showcasing individual creativity in punctuation application.
