Final answer:
Children with autism may display challenging behavior due to skill deficits, sensory overload, and difficulties in expressing needs and emotions.
Step-by-step explanation:
Children with autism may display challenging behavior due to a combination of factors. One reason could be skill deficits, as children with autism may struggle with social skills, communication, and emotional regulation. Another factor could be sensory overload, as children with autism may be more sensitive to stimuli such as lights and noises. Additionally, some challenging behavior may arise from difficulties in expressing their needs and emotions.
