What is autism?
Autism is one of the autism spectrum disorders, a group of conditions that vary in their severity and the age at which a child first may show symptoms. Autism spectrum disorders fall under a broader category known as pervasive developmental disorders (PDDs). PDDs cause delays in many areas of childhood development, such as the development of skills to communicate and interact socially.
Autism typically is diagnosed during a child’s second year and is lifelong, although symptoms may lessen over time. There is no cure for autism, but appropriate treatments can help a child develop life skills to function more independently.
Who as affected by autism?
Autism is one of the most common developmental disabilities. It affects people of every race, ethnic group, and socioeconomic background. Boys are four times more likely to have autism than are girls. According to a study by the Centers for Disease Control and Prevention (CDC), autism spectrum disorders were found to affect an average of one out of every 110 8-year-ancient children.
How does autism affect communication in children?
The word “autism” has its origin in the Greek word “autos,” which means “self.” Children with autism often are self-absorbed and seem to exist in a private world where they are unable to successfully communicate and interact with others. Children with autism may have difficulty developing language skills and understanding what others say to them. They also may have difficulty communicating nonverbally, such as through hand gestures, eye contact, and facial expressions.
Not every child with an autism spectrum disorder will have a language problem. A child’s ability to communicate will vary, depending upon his or her intellectual and social development. Some children with autism may be unable to speak. Others may have rich vocabularies and be able to talk about specific subjects in fantastic detail. Most children with autism have small or no problem pronouncing words. The majority, but, have difficulty using language effectively, especially when they talk to other people. Many have problems with the meaning and rhythm of words and sentences. They also may be unable to know body language and the nuances of vocal tones.
Below are some patterns of language use and behaviors that are often found in children with autism.
- Repetitive or rigid language. Often, children with autism who can speak will say things that have no meaning or that seem out of context in conversations with others. For example, a child may count from one to five repeatedly. Or a child may continuously repeat words he or she has heard, a condition called echolalia. Immediate echolalia occurs when the child repeats words someone has just said. For example, the child may respond to a question by asking the same question. In delayed echolalia, the child will repeat words heard at an earlier time. The child may say “Do you want something to drink?” whenever he or she questions for a drink.
Some children with autism speak in a high-pitched or singsong voice or use robot-like speech. Other children with autism may use stock phrases to start a conversation. For example, a child may say “My name is Tom,” even when he talks with friends or family. Still others may repeat what they hear on television programs or commercials.
- Narrow interests and exceptional abilities. Some children may be able to deliver an in-depth monologue about a topic that holds their interest, even though they may not be able to carry on a two-way conversation about the same topic. Others have musical talents or an advanced ability to count and do math calculations. Approximately 10 percent of children with autism show “savant” skills, or extremely high abilities in specific areas, such as calendar calculation, music, or math.
- Uneven language development. Many children with autism develop some speech and language skills, but not to a normal level of ability, and their progress is usually uneven. For example, they may develop a strong vocabulary in a particular area of interest very quickly. Many children have excellent memories for information just heard or seen. Some children may be able to read words before 5 years of age, but they may not comprehend what they have read. They often do not respond to the speech of others and may not respond to their own names. As a result, children with autism sometimes are mistakenly thought to have a hearing problem.
- Poor nonverbal conversation skills. Children with autism often are unable to use gestures—such as pointing to an object—to give meaning to their speech. They often avoid eye contact, which can make them seem rude, uninterested, or inattentive. Without meaningful gestures or the language to communicate, many children with autism become frustrated in their attempts to make their feelings and needs known. They may act out their frustrations through vocal outbursts or other inappropriate behaviors.
