Morphosyntactic skills in Arabic-speaking children with autism spectrum disorder: Evidence from error patterns in the sentence repetition task

Table of Contents



Autism Spectrum Disorder (ASD) presents a complex picture when it comes to language development. Children on the spectrum can exhibit a wide range of abilities, from excelling in specific areas like memorization to struggling with fundamental communication skills. A recent study published in April 2024 sheds light on this topic by investigating the morphosyntactic skills of Arabic-speaking children with ASD.


Demystifying Morphosyntax: The Building Blocks of Language


Before diving into the study, let’s establish a common ground. Morphosyntax is a fancy term for the foundation of language – how we combine sounds (morphology) and words (syntax) to create grammatically correct sentences. Imagine morphosyntax as the set of instructions that allows us to transform individual words like “run” and “boy” into a meaningful sentence like “The boy runs.” This includes skills like:

  • Using verb conjugations (e.g., “run” becomes “runs” to indicate present tense)
  • Adding prefixes and suffixes (e.g., adding “-ing” to “run” to create the present participle)
  • Arranging words in the proper order (e.g., “boy runs” vs. “runs boy”)


Mastering morphosyntax is essential for clear and effective communication.


Sentence Repetition: A Window into Language Processing


The researchers behind the April 2024 study employed a clever technique to assess the morphosyntactic abilities of Arabic-speaking children with ASD – the sentence repetition task. Here’s how it works: children listen to sentences spoken in Arabic and then try to repeat them exactly. It might seem simple, but analyzing errors made during repetition provides valuable insights.


Imagine a child with ASD hears the sentence “الكتاب الذي يقرأه عمر جميل” (Al-kitabu allathi yaqraʾuhu Omar jamīl) which translates to “The book that Omar is reading is beautiful.” If the child struggles and repeats it as “كتاب جميل” (Kitabu jamīl) meaning “Beautiful book,” this indicates a difficulty with processing the relative clause structure (” الذي يقرأه عمر” – allathi yaqraʾuhu Omar).


By analyzing these errors, researchers can gain a deeper understanding of a child’s grasp of grammatical rules and their ability to apply them in real-time speech production.


A Spectrum of Language Abilities Emerges


The study yielded a fascinating finding – the children with ASD fell into two distinct subgroups:

  1. ASD + NL (Age-Appropriate Language): This group displayed morphosyntactic skills on par with typically developing children. Their performance on the sentence repetition task suggested a good understanding of Arabic grammar rules. They were able to repeat complex sentences, including those with relative clauses and wh-questions, with a high degree of accuracy.
  2. ASD + LI (Morphosyntactic Impairment): This group exhibited difficulties with morphosyntax, particularly when dealing with complex sentence structures. They often struggled with sentences involving relative clauses (like the example mentioned earlier) and object wh-questions (questions like “ماذا يقرأ عمر؟” – ماذا yadraʾu Omar? – meaning “What is Omar reading?”). Their errors during repetition often involved producing shortened versions of the sentences (e.g., omitting the relative clause) or simplifying the sentence structure.


This finding highlights the heterogeneity within the ASD population. Even among Arabic-speaking children, there can be significant variations in language skills.


Morphosyntax Takes Center Stage: Pragmatics Follow Suit


Another interesting aspect of the study involved the nature of errors made during sentence repetition. The researchers found that both groups, ASD + NL and ASD + LI, made more morphosyntactic errors than pragmatic errors. Pragmatics refers to how language is used in social contexts, such as understanding sarcasm or turn-taking in conversation.


This suggests that for these children with ASD, the core challenge lies in mastering the grammatical aspects of language, rather than using language appropriately in social settings. They might understand the social situation perfectly well but struggle to express themselves due to difficulties with forming grammatically correct sentences.


Implications for Tailored Interventions


The April 2024 study offers valuable insights for understanding and supporting children with ASD. It emphasizes the importance of recognizing individual variations in language profiles. A child with ASD + NL may benefit from different interventions compared to a child with ASD + LI.


For children with ASD + LI, targeted interventions focusing on specific morphosyntactic structures like relative clauses and wh-questions can be crucial. Speech therapists and language pathologists can develop exercises and strategies to help them grasp these concepts and improve their sentence construction skills.


This research paves the way for developing more effective and individualized interventions for Arabic-speaking children with ASD.



Does this study apply to children with ASD who speak languages other than Arabic?


The current study focused on Arabic-speaking children with ASD, but the core findings may hold relevance for children with ASD speaking other languages. Morphosyntax is a universal concept, and the challenges identified in the study, such as difficulties with complex sentence structures, might be observed across languages. However, further research is needed to explore how these difficulties manifest in different language systems.


Are there limitations to using sentence repetition tasks to assess language skills in children with ASD?


Sentence repetition tasks offer valuable insights, but they have limitations. For instance, a child might possess good auditory processing skills and be able to repeat sentences accurately through rote memorization, even if they don’t fully grasp the underlying grammar. Additionally, children with ASD may experience anxiety or performance pressure during testing situations, which could affect their performance on the task. For a more comprehensive assessment, combining sentence repetition tasks with other methods like analyzing spontaneous speech samples is ideal.


What are some other ways to assess morphosyntactic skills in children with ASD?


Beyond sentence repetition, various methods can be used to assess morphosyntactic skills in children with ASD. These include:

  • Picture description tasks: Children describe pictures or scenarios, allowing researchers to analyze their sentence structure and use of grammar.
  • Grammar comprehension tasks: Children are presented with grammatically correct and incorrect sentences and asked to identify the correct ones.
  • Story completion tasks: Children are given partial stories and asked to complete them, revealing their ability to use grammar to construct coherent narratives.


By employing a variety of techniques, researchers can gain a more nuanced understanding of a child’s morphosyntactic strengths and weaknesses.


The study mentions ASD + NL and ASD + LI. Are these formally recognized subtypes of ASD?

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the standard reference for diagnosing mental disorders, does not classify ASD into subtypes based on language ability. However, researchers sometimes use terms like ASD + NL (typical language) and ASD + LI (language impairment) to describe these variations within the ASD population. These designations can be helpful for understanding individual differences and tailoring interventions.


Could the differences between ASD + NL and ASD + LI groups be due to intellectual ability?


Intellectual ability can be a factor, but the study doesn’t necessarily imply a direct link. Children with ASD + LI may have underlying cognitive factors contributing to their morphosyntactic difficulties. However, the study focused on morphosyntax and didn’t assess intellectual ability. Further research exploring the interplay between cognitive factors, ASD subtypes, and language development is needed.


The study mentions pragmatic errors. Can you elaborate on the types of pragmatic errors observed?


The study found that both groups made fewer pragmatic errors compared to morphosyntactic errors. This suggests that understanding the social use of language might be less challenging for these children than mastering the grammatical aspects. However, pragmatic errors can still occur in ASD and might manifest in various ways, such as:

  • Difficulty with turn-taking in conversation
  • Challenges with understanding nonverbal cues like facial expressions or body language
  • Taking things too literally or struggling with figurative language like sarcasm


These are just a few examples, and the specific types of pragmatic errors can vary depending on the individual child.


This study suggests that children with ASD + NL perform similarly to typically developing children on the sentence repetition task. Does this mean they have no language delays?


The study indicates that children with ASD + NL performed well on the sentence repetition task, a specific measure of morphosyntactic skills. However, it doesn’t necessarily rule out the possibility of other language delays. Children with ASD + NL might still experience challenges in areas like:

  • Pragmatics: Using language appropriately in social contexts, such as understanding sarcasm or turn-taking in conversation.
  • Vocabulary development: Knowing and using a wide range of words.
  • Narrative skills: The ability to tell stories with a clear beginning, middle, and end.


A comprehensive evaluation that considers various aspects of language development is essential for identifying any potential delays beyond morphosyntax.


The research focused on sentence repetition. Are there other tasks that can help parents identify morphosyntactic difficulties at home?


While sentence repetition tasks are valuable tools used by professionals, parents can observe their child’s communication patterns at home to identify potential morphosyntactic difficulties. Here are some signs to look for:

  • Difficulty using complex sentence structures: Does your child primarily use short, simple sentences?
  • Frequent grammatical errors: Does your child make mistakes with verb conjugations, plurals, or subject-verb agreement?
  • Struggles to follow instructions with multiple steps: Does your child have trouble understanding instructions that involve several sequential actions?


If you notice any of these signs, consulting a speech-language pathologist can be beneficial for a more formal assessment and targeted intervention strategies.


Children with ASD + LI struggled with relative clauses in the study. How can parents encourage their children to understand these complex structures?


Relative clauses can be challenging, but parents can help their children with ASD + LI develop an understanding of them. Here are some strategies:

  • Start with simpler examples: Begin with short relative clauses like “the book that I am reading” before moving on to more complex structures.
  • Use visuals: Draw pictures or diagrams to represent the relationship between the main clause and the relative clause.
  • Break down the sentence: Read the sentence one clause at a time, emphasizing the who or what the relative clause refers to.
  • Practice with manipulatives: Use toys or objects to physically demonstrate the relationship between the main clause and the relative clause.


By incorporating these techniques into everyday interactions, parents can help their children grasp the concept of relative clauses in a gradual and engaging way.


Are there any treatments specifically designed to address morphosyntactic difficulties in ASD?


There isn’t a single, one-size-fits-all treatment for morphosyntactic difficulties in ASD. However, speech-language pathologists can employ various interventions tailored to a child’s specific needs. These might include:

  • Explicit grammar instruction: Breaking down grammatical concepts into manageable steps and teaching them directly.
  • Social communication interventions: Combining grammar instruction with social communication training to help children understand how to use language appropriately in different contexts.
  • Visual supports: Utilizing visuals like charts or diagrams to represent grammatical structures and aid comprehension.


The effectiveness of these interventions depends on the individual child and the severity of their morphosyntactic difficulties.


How important is early intervention for improving morphosyntactic skills in children with ASD?


Early intervention is crucial for maximizing a child’s language development potential. When morphosyntactic difficulties are identified early, targeted interventions can be implemented during a period of heightened neuroplasticity in the brain. This can significantly improve a child’s ability to learn and master grammatical rules.


How can parents support the morphosyntactic development of their child with ASD at home?


Here are some strategies parents can use to support their child with ASD at home:

  • Narrate daily routines: Talk through everyday activities, describing what you and your child are doing using grammatically correct sentences.
  • Read together: Engage in story time, pointing out sentence structures and explaining the use of different grammatical elements.
  • Sing songs and rhymes: Songs and rhymes provide exposure to language patterns and can be a fun way to introduce new vocabulary and grammar concepts.
  • Play games: Games that involve storytelling or creating narratives can encourage children to use their language skills in a relaxed and enjoyable setting.


It’s important to remember that every child develops at their own pace. If you have concerns about your child’s language development, consulting a speech-language pathologist can be beneficial.
