This study investigates the acquisition of English verb movement phenomena by two groups of adult French native speakers: a group of secondary school students and a group of university students. A group of English native speakers served as controls. Participants were administered a written questionnaire composed of a controlled production task, a grammaticality judgment task, and a preference/grammaticality judgment task, to test acquisition of the syntactic properties associated with the verb movement parameter (Pollock 1989, 1997). Instead of substantiating the anecdotal evidence that suggests that adverb placement errors persist into very advanced stages of English L2 acquisition, the present data support the successful acquisition of English adverb placement by French native speakers. It is argued that the advanced group has acquired the appropriate L2 parametric value as measured by the controlled production task; while results on the other two tasks are explained by performance effects.
