Purpose: Derivational morphology and compounds are important aspects of academic vocabulary. However, investigation of the development of expressive derivational and compound morphology using language sampling is sparse. This cross-sectional study used three types of language samples to investigate quantitative and qualitative changes in the…

There is broad consensus that printed complex words are identified on the basis of their constituent morphemes. This fact raises the issue of how the word identification system codes for morpheme position, hence allowing it to distinguish between words like "overhang" and "hangover", and to recognize that "preheat" is…

The spellings of many English words follow a principle of morphological constancy. For example, "musician" includes the c of "music", even though the pronunciation of this letter changes. With other words, such as "explanation" and "explain", the spellings of morphemes are not retained when affixes are…

English-speaking children typically avoid using regular plurals in novel grammatical deverbal compounds as in "rat eater" but allow irregular plurals as in "mice eater" (Gordon, 1985). To explain these data, it has been argued that Kiparsky's (1983) level-ordering model constrains the production of morphologically complex…

Examines the use of tense, agreement, and non-tense morphemes and associated distributional contingencies in the language production of Quebec French-Speaking children with specific language impairment and normally developing language and age-matched controls. Sought to determine whether the optimal infinitive/extended optional infinitive pattern…

Two experiments investigated morphological decomposition in ambiguous novel compounds such as "busheater," which can be parsed as either "bus-heater" or "bush-heater." It was found that subjects' parsing choices for such words are influenced by orthographic constraints but that these constraints do not operate…

Background: Although a number of studies have been conducted on normal acquisition in French, systematic methods for analysis of French and normative group data have been lacking. Aims: To develop a systematic method for the analysis of language samples in Quebec French, and to provide preliminary normative data on early lexical and syntactic…
