What are the differences in how children with ADHD and ASD communicate?
Min Jung KwonShare
Last time, we discussed the similarities and differences in the social skills of ASD and ADHD. Today, we'll continue by exploring the similarities and differences in their communication styles and discuss appropriate intervention methods for each child.

Children with both ADHD and ASD can experience communication difficulties. However, these difficulties can manifest in slightly different ways and have different causes.
To help parents and therapists understand what supports best meet a child's needs, it's important to first understand the differences and similarities in communication.
Causes of Communication Difficulties in Children with ADHD and ASD
If children with ADHD have difficulty understanding the purpose or structure of conversation due to problems with attention and impulsivity , it is better to understand that children with ASD have difficulty understanding the basic rules of social interaction .
1) Children with ADHD
Attention problems and impulsivity:
- Children with ADHD tend to have difficulty paying attention and exhibit impulsive behavior during conversations.
- They are easily distracted by external stimuli during conversations or tend to interrupt others to speak first . They often abruptly interrupt others while they are speaking to express their own thoughts.
- This can make it difficult to maintain a conversation and can make the other person feel ignored.
2) Children with ASD
Difficulty interpreting social cues:
- Children with ASD often have difficulty interpreting social cues such as facial expressions, gestures, and eye contact .
- They may have difficulty understanding other people's emotional states or reading nonverbal cues during conversations, and often engage in one-sided conversations .
- You may find it difficult to communicate with others because you seem to keep talking about topics you like regardless of the other person's reaction, and you often make little eye contact or have no facial expressions during conversations.

Communication in children with ADHD and ASD
Both children with ADHD and ASD may frequently stray from the topic or interrupt the flow of conversation during conversations. They may also have difficulty recognizing and responding appropriately to nonverbal cues, potentially leading to misunderstandings.
However, children with ADHD don't simply fail to recognize the rules or signals of conversation. Children with ASD simply fail to recognize these very concepts.
1) Difficulty maintaining the purpose or structure of the conversation
Children with ADHD:
- Due to attention problems and impulsivity, rather than considering the flow or structure of the conversation We tend to react to immediate stimuli .
- Normally, we tend to have a conversation by listening to what the other person says and responding to it, but children with ADHD tend to cut off the conversation. It disrupts the flow of interactive conversation .
- The topic of conversation is easily distracted because attention is easily distracted. It can be difficult to maintain consistency If the topic keeps changing, the conversation can become disjointed and confusing for the other person.
Children with ASD:
- Unlike children with ADHD, they have fundamental difficulties understanding social rules or basic principles of conversation.
- They may not understand the order of conversation or the rules of interaction themselves, and may not naturally learn basic conversation rules such as "who speaks when and who should wait while the other person speaks."
- I have difficulty changing the topic of conversation or adjusting the topic to suit the other person's opinion.
- Conversations often flow more like information transfer than interaction.
2) Problems with interpreting nonverbal signals
Children with ADHD:
- You may miss nonverbal cues such as facial expressions or gestures due to distraction or lack of attention.
- Because you immediately speak or act out your thoughts before interpreting nonverbal cues, you may appear to flow out of sync with the flow of the conversation.
- And even if you happen to notice these signals (for example, if you notice the other person is angry), you may not be able to recognize them or miss the timing to react because you are focused on other thoughts or stimuli.
Children with ASD:
- You may not be able to recognize nonverbal cues such as facial expressions, eye contact, and gestures, or even if you do recognize them, you may not know what they mean .
- The other person appears to have difficulty interpreting emotional signals, such as a slight frown or averted eyes.
- The fundamental reason we don't understand these signals is because we don't understand the importance of social interaction .
Today we looked at two communication styles that seem similar but are different.
I hope this helps those who are frustrated because their children's communication skills are not improving or who want to understand their children's communication methods a little more deeply.
There are also different ways to develop communication skills between the two. We'll continue on that in the next article!
