The purpose of the study was to investigate the discourse elicitation task effect and whether it affects the production of verbs with different semantic weight (light verbs with vague semantic representations, e.g., ‘do’, or heavy verbs with specific semantic representations, e.g., ‘deliver’). Thirty people with non-fluent aphasia and twenty people without aphasia were included. The light and heavy verb ratios over the total number of verbs were calculated for two discourse elicitation tasks: sequential picture description and storytelling. The results for the healthy control group showed that they produced a significant higher heavy verb ratio in sequential picture description than in storytelling and that they produced a significantly higher light verb ratio in storytelling than in sequential picture description. The results for the people with non-fluent aphasia showed that they produced a significantly higher heavy verb ratio in storytelling than in sequential picture description and that there was no significant difference between the light verb ratios for the two tasks.
