A negative symptom of ASD (autism spectrum disorder) is difficulty in social interaction. Those with ASD often struggle to interact with others and maintain relationships with peers, family members, and other adults. This difficulty may be due to the person's difficulty in understanding social cues, or difficulty in expressing their own feelings and emotions. It may also be due to difficulties in understanding abstract concepts, such as humor, sarcasm, and the implications of certain words or phrases.
People with ASD may have difficulty initiating conversations, maintaining eye contact, or engaging in appropriate body language. They often appear to be uninterested in others and may have difficulty showing empathy or understanding others' feelings.
People with ASD may find it difficult to engage in cooperative play or group activities, as they may have difficulty understanding the rules or following directions. They may also have difficulty with non-verbal communication, such as facial expressions, gestures, or understanding the tone of voice, which can make social interactions confusing and challenging.
In addition, people with ASD may have difficulty with sensory processing, which can make it difficult for them to cope with loud noises, bright lights, or certain textures. This can make it difficult for them to function in a typical social environment, such as a classroom or a playground.
Overall, difficulty in social interaction is a major negative symptom of ASD, and can have a significant impact on a person's ability to interact with others and form relationships.
