<unk> s are classified as either motor or phonic, and simple or complex. Motor or phonic Motor<unk> s are movement-based<unk> s affecting discrete muscle groups. Phonic<unk> s are involuntary sounds produced by moving air through the nose, mouth, or throat. They may be alternately referred to as verbal<unk> s or vocal<unk> s, but most diagnosticians prefer the term phonic<unk> s to reflect the notion that the vocal cords are not involved in all<unk> s that produce sound. Simple or complex Simple motor<unk> s are typically sudden, brief, meaningless movements that usually involve only one group of muscles, such as eye blinking, head jerking, or shoulder shrugging. Motor<unk> s can be of an endless variety and may include such movements as hand clapping, neck stretching, mouth movements, head, arm or leg jerks, and facial grimacing. A simple phonic<unk>  can be almost any sound or noise, with common vocal<unk> s being throat clearing, sniffing, or grunting. Complex motor<unk> s are typically more purposeful-appearing and of a longer nature. They may involve a cluster of movements and appear coordinated. Examples of complex motor<unk> s are pulling at clothes, touching people, touching objects, echopraxia (repeating or imitating another person's actions) and copropraxia (involuntarily performing obscene or forbidden gestures). Complex phonic<unk> s include echolalia (repeating words just spoken by someone else), palilalia (repeating one's own previously spoken words), lexilalia (repeating words after reading them), and coprolalia (the spontaneous utterance of socially objectionable or taboo words or phrases). Coprolalia is a highly publicized symptom of Tourette syndrome; however, only about 10% of TS patients exhibit coprolalia. Martino, et al have argued that<unk> s may be considered physiological, or developmentally typical.
