1) A female subject complaining of delayed speech was observed in respect to the development of oral and written language over a period of four years, starting at age 5 years 10 months.
2) In contrast to relatively satisfactory development of speech comprehension, development of speech output was remarkably delayed. The subject showed various specific developmental patterns of articulation including derivational errors towards a correct articulation and phonemic substitutions, which suggested fundamental disorder of motor programming for articulation.
3) The development of written language was severely delayed in all aspects-oral reading, reading comprehension and writing-even after oral language was quite advanced. Analysis of the subject's difficulties in reading and writing using information processing models of reading and writing suggested developmental disorders of phonemic analysis and synthesis which were presumed to have been caused by the difficulties in motor programming for articulation.
