Language Development in Children with Autism Spectrum Disorder

The growth and development of language skills represents an essential and important stage for a child's typical development. Children generally go through the same stages of language development, despite various factors such as differences in the linguistic environment and the language the child is learning, in addition to individual differences in intelligence or social communication ability, the extent of parental interaction and language use with their children, the surrounding culture, and so on.

However, not all children continue to develop their language skills adequately in a way that enables them to use language correctly and effectively to achieve effective social communication. The presence of a delay or impairment in language is a clear sign of developmental issues. More importantly, studying such issues can also help in understanding the nature of the language acquisition process.

Signs of Language Development Delay in Children with Autism

The presence of a delay in language development in children who are later diagnosed with autism spectrum disorder is considered the first sign parents notice in their children during the first two years of life (noting that not every language delay necessarily means the child has autism). Among the difficulties experienced by children with autism, in addition to impaired sensory and social communication and restricted, repetitive behaviors, is delayed language development.

Linguistic communication deficits in individuals with autism include a variety of language problems, ranging from:

• Complete absence of language
• Using stereotyped speech or repeating certain phrases
• Difficulty initiating and sustaining conversations with others
• There are cases of those who can use language fluently with some difficulties in the pragmatic uses of language, such as understanding figurative expressions including metaphors and sarcasm.

Studies on Language Development in Children with Autism

Recent studies indicate that approximately 25% of individuals with autism spectrum disorder do not acquire any ability to express themselves using language. While some researchers suggest that language problems in children with autism stem from a deficit in social communication ability and that core language skills (such as phonology and syntax) remain intact, research nonetheless indicates significant language impairment across all individuals with autism.

There is also considerable heterogeneity in the timing and patterns of language acquisition among individuals with autism, such that the ability of children with this disorder to communicate and use language depends on their cognitive and social development.

Sometimes children with autism begin speaking later than other non-affected children; while a typically developing child begins uttering their first words in the first year of life, a child with autism begins uttering their first words between the ages of 2 and 3 years, and language development generally continues at a slower pace compared to their peers.

By the second year of life, children with autism show different communication patterns compared to children who acquire language typically. For example, while a typical child demonstrates a response to their name around the fourth to sixth month, children diagnosed with autism show a limited response at 12 months of age upon hearing their names, hearing their mothers' voices, or hearing the simple speech used with children.

Studies conducted on infants and toddlers with autism have suggested that between 12 and 24 months of age, these young children who were later diagnosed with autism spectrum disorder understand significantly fewer phrases and use fewer gestures, facial expressions, and nonverbal cues than typical rates in children.

Development of Joint Attention Skills and Word Comprehension

Before children begin uttering their first words, various factors linked to child development and the progression of their social communication ability are closely tied to language development in children generally, such as imitation, play, gestures, and what is known as joint attention. It is well known that joint attention skills are fundamental to developing social and communication skills among children and play an important role in language development.

Joint attention skills are defined as the ability of children to coordinate attention on a shared object with people around them. For example, a child learns about objects in the surrounding environment early on through the process of joint attention, as parents provide an opportunity to learn object names by pointing to a new object or a new event in the environment. From six months of age, the child can follow the parents' gaze toward objects in the environment, helping them know what the speaker is referring to, and the ability to use these skills develops over time to become more complex.

Studies indicate a close link between joint attention skills and the development of word acquisition and comprehension, and that variations in children's response to joint attention may adversely affect language development, which may be a reason for language delay in children with autism. Studies have shown that children with autism usually have difficulty using joint attention skills spontaneously and integratively at an early age, affecting their language development and communication progress. Children with autism are less likely than their typically developing peers to respond to or initiate joint attention using vocalizations or gestures such as pointing to something new to draw adults' attention.

Language Use in the Context of Social Communication

Recent research indicates that even in individuals with autism who possess linguistic ability, the pragmatic aspect of language is usually weaker than in typical individuals. The concept of "pragmatics" in language refers to using language as a tool for social communication between individuals, including how language is used within the context of social communication, such as:

Changing the way of speaking depending on the person being addressed, paying attention to conversational turn-taking, and understanding figurative language, proverbs, and indirect speech, as well as non-verbal functions such as eye contact, body language, and facial expressions.

Pragmatics is considered one of the most socially driven domains of language, as it requires the speaker to be fully aware of the social and cognitive state of the speaker; these language skills develop during the first five years of a child's life, but for children with autism, the pragmatic aspect is the weakest area of language. Studies indicate that children and adults with autism interpret speech literally and have difficulty understanding what others intend to say. For example, individuals with autism find it difficult to understand metaphors and grasp word meanings through context, so they often interpret speech literally without attributing other meanings to words or expressions.
