Linguistics

You are interested to find out whether L2 learners rely on case information when processing sentences in a language that marks case information on the nouns (and elements that go along with them). For instance, nouns marked for nominative are the subject of the sentence, whereas nouns marked for accusative are the object of the verb. Examples of such languages are German, Latin, Russian, etc. Note that these languages do not have the same number of cases, but this should not matter for your response.
Your task: Decide on the psycholinguistic technique that you think would be best to use to find out the answer to this research question. Explain why you think that technique would be ideal (think about the actual design of the study you would create).
