 This distinguishes them from conventional implicatures.In a 2006 experiment with Greek-speaking five-year-olds' interpretation of aspectual expressions, the results revealed that children have limited success in deriving scalar implicatures from the use of aspectual verbs such as "start" (which implicates non-completion).However, the tested children succeed in deriving scalar implicatures with discrete degree modifiers such as "half" as in half finished.
