This study investigates (a) the effectof argument structure on verb retrieval and (b) theinterrelation between inflection marking and verb retrievalin SD.Method: Seven individuals with SD and 7 healthy controlsperformed 2 sentence elicitation tasks. In Experiment 1,participants described the action taking place in a video.In Experiment 2, they watched the same videos precededby a phrase prompting the production of past tense.Three verb classes were tested: (a) unergative (e.g., towalk), (b) unaccusative (e.g., to fall ), and (c) transitive with1 object (e.g., to read a book).Results: There was not any quantitative difference amongthe verb classes in Experiment 1, but error analysis hintedat difficulties related with argument structure complexity.The findings of Experiment 2 suggest no general effect ofinflection on verb retrieval; nevertheless, inflection markingimpeded the retrieval of verbs with complex argumentstructure. Large individual variation was established.Conclusions: Argument structure complexity may challengespeakers with SD. Verb retrieval and inflection markingseem to interrelate at the expense of the former. Inflectionproduction may be affected at severe stages of the disease.Supplemental Material S1.
