Naturalistic studies show that children can create language-like communication systems in the absence of conventional language. However, experimental evidence is mixed. We address this discrepancy using an experimental paradigm that simulates naturalistic sign creation. Specifically, we tested if a sample of 6- to 12-year-old children (52 girls…

Previous studies measuring praxis abilities in young autistic children have only used praxis measures that were not optimised for autistic individuals. Hence, we used the FAB-R to measure praxis skills in autistic (n = 38) and typically developing (TD) children (n = 38) aged between four and 10 years. Praxis abilities were generally not different…

The purpose of this study was to explore the spelling knowledge and skills of elementary school children with and without dyslexia who speak Dutch, a language with a relatively transparent orthography. Children in Grades 2-6 completed real and pseudoword spelling dictation tasks. Spelling performance was compared in 218 children with (n = 55) and…

Introduction: Baddeley's model of working memory establishes the basis for identifying components that intervene in immediate repetition verbal tasks. Based on this model, the overall aim of the present study was to analyze the relationship between auditory sequential memory and verbal memory in students with intellectual disabilities and thereby…

We explored the vocabulary and metaphor comprehension of learners of English as an additional language (EAL) in the first two years of UK primary school. EAL vocabulary knowledge is believed to be a crucial predictor of (reading) comprehension and educational attainment (Murphy, 2018). The vocabulary of five- to seven-year-old children with EAL…

Studying anxiety in neurogenetic syndromes may inform the intersection of biological and developmental risks, facilitating effective and targeted interventions. We longitudinally examined stranger fear in infants and toddlers with fragile X syndrome (FXS; n = 46) and typical controls (n = 33), as well as associations between observed stranger fear…

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…

Background: The ability to generate words that follow certain constraints, or verbal fluency, is a sensitive indicator of neurocognitive impairment, and is impacted by a variety of variables. Aims: To investigate the effect of post-stroke aphasia, elicitation category and linguistic variables on verbal fluency performance. Methods &…

Purpose: This longitudinal study examined differences in the development of working memory (WM) between children with specific language impairment (SLI) and typically developing (TD) children. Further, it explored to what extent language at ages 7-8 years could be predicted by measures of language and/or WM at ages 4-5 years. Method: Thirty…

Linking relations described in text with relations in visualizations is often difficult. We used eye tracking to measure the optimal way to extract such relations in graphs, college students, and young children (6- and 8-year-olds). Participants compared relational statements ("Are there more blueberries than oranges?") with simple…

The United Nations Educational, Scientific, and Cultural Organization promoted the creation of a model instrument for individual assessment of students' foundational writing skills in the Spanish language that was based on a literature review and existing writing tools and assessments. The purpose of the "Early Grade Writing Assessment"…

The aim of this study was to analyze whether children with and without difficulties in handwriting, spelling, or both differed in alphabet writing when using a keyboard. The total sample consisted of 1,333 children from Grades 1 through 3. Scores on the spelling and handwriting factors from the "Early Grade Writing Assessment" (Jiménez,…

This study investigated neurodevelopmental changes in sound processing by recording mismatch negativity (MMN) in response to various degrees of sound complexity in 18 mildly to moderately autistic versus 15 healthy boys aged between 6 and 15 years. Autistic boys presented with lower IQ and poor performance on a range of executive and social…

Background: Young children's speech is typically more linguistically sophisticated than their writing. However, there are grounds for asking whether production of cohesive devices, such as verb-phrase anaphora (VPA), might represent an exception to this developmental pattern, as cohesive devices are generally more important in writing than in…

Background: Previous research suggests that speakers are especially likely to produce manual communicative gestures when they have relative ease in thinking about the spatial elements of what they are describing, paired with relative difficulty organizing those elements into appropriate spoken language. Children with specific language impairment…
