Developmental language disorders: cognitive processes, semantics, pragmatics, phonology, and syntax.
Language disorders in autism and delay are multi-part puzzles—test all five areas, not just grammar.
01Research in Context
What this study did
Skinner (1981) looked at every piece of language a child with autism or developmental delay might show. The review asked how five parts—thinking skills, word meaning, social use, sounds, and grammar—work together.
The paper says we must test all five parts, not just one. It warns that looking at grammar alone hides the full picture.
What they found
The review found that language disorders are puzzles. Each piece affects the others. A child may speak in short sentences because of weak grammar, poor word meaning, or trouble with social rules.
No single test can show why the child struggles. You need many probes across many areas.
How this fits with other research
Onnis et al. (2018) built on this idea. They added genes and the child’s learning history to the same five-part model. The 2018 paper is the successor—it keeps the 1981 frame and adds new layers.
Dudley et al. (2019) tested only grammar. They showed that kids with autism need a mental age near seven before they can grasp hard grammar like passive voice. This finding extends the 1981 call to link grammar with age and diagnosis.
Kalliontzi et al. (2022) looked at preschoolers with language delay. They showed that weak executive functions, like updating memory, travel with weak language. This extends the 1981 view by naming a new thinking skill that may drive the problem.
Why it matters
Stop using one score to plan language goals. Run short checks on meaning, social use, sounds, grammar, and thinking skills. If grammar is stuck, test word meaning and executive functions next. Match targets to the child’s weakest link, not the label.

03Original abstract
Five areas of research concerned with language acquisition--cognitive processes, semantics, pragmatics, phonology, and syntax--are reviewed in terms of their contribution to understanding language disorders. Two views of cognitive processes are discussed. One of these, emphasizing cognitive mechanisms such as short-term memory, is seen as providing possible explanations for some types of language deficits. The other, a concern with conceptual knowledge, is subjected to a critical analysis questioning how complete an explanation it is able to offer for some aspects of language acquisition. Problems of definition are also discussed when semantic aspects of language are considered. Problems in the pragmatic component of language are seen as providing an explanation for particular aspects of language disorder in some autistic children. The importance of focusing on phonology as a central grammatical process is discussed and linked to dyslexia and to spelling disorders. Finally, it is argued that the acquisition of syntactic structure is not yet understood. Impairments such as a hierarchical planning order deficit may affect syntactic ability and lead to disordered language, as found in some types of developmentally aphasic children. It is concluded that it is important to study all five areas of the title, and their interrelationships, if various language disorders are to be adequately understood.
