Children with AS often display advanced abilities for their age in language, reading, mathematics, spatial skills, or music—sometimes into the "gifted" range—but this may be counterbalanced by considerable delays in other developmental areas, like verbal and nonverbal communication or some lack of motor coordination. This combination of traits can lead to problems with teachers and other authority figures. A child with AS might be regarded by teachers as a "problem child" or a "poor performer." The child's extremely low tolerance for what they perceive to be ordinary and mundane tasks, such as typical homework assignments, can easily become frustrating; a teacher may well consider the child arrogant, spiteful, and insubordinate. Lack of support and understanding, in combination with the child's anxieties, can result in problematic behavior (such as severe tantrums, violent and angry outbursts, and withdrawal).
