Final answer:
In American Sign Language, 'not yet' would be signed just after 'we' to emphasize that the subject has not yet performed the action of studying.
Step-by-step explanation:
When signing the statement "we have not studied for the test yet," you would sign "not yet" just after signing "we". In American Sign Language (ASL), the order of signs typically follows the subject-verb-object structure, but can vary based on the emphasis and context of the sentence. By signing "not yet" immediately after the subject "we," it places emphasis on the fact that the studying has not occurred but is anticipated.
