Communication refers to the conveyance of intended messages so that the listeners' attitudes, beliefs, or behaviors are changed. Communication through a language system may be thought of as the integration of the three components of content (semantics), form (syntax), and use (language in context or pragmatics). The corning together of content, form, and use in signs, words, phrases, and discourse is the essence of language development. The synergism of content/form/use makes up language competence, or knowledge. When children speak and understand a message, they have a plan that is knowledge of language and they use that plan for the behavior involved in speaking or understanding messages, (Bates, 1976; Bloom and Lahey, 1978).

The problem of this investigation was to compare the linguistic competence of learning disabled and emotionally disturbed pupils by means of two performance tasks. Sixty subjects, seven-and-eight-year old monolingual public and private school pupils, were assigned to three groups of twenty subjects each, learning disabled, emotionally disturbed and normally achieving children. The majority of those in the learning disabled and the normally achieving groups were from middle-class families, with the majority of fathers owners of small businesses. A majority (17) of the emotionally disturbed group attended the public schools.
