What are the relative strengths and weaknesses of the available theoretical models relating to Conceptual Metaphor Theory (CMT) in the context of Second Language Acquisition (SLA)? Is new empirical research needed as their approaches are only considered as a theoretical construct that other users may not get it as a verification of hypotheses to validate? Would researchers be able to add further prospective models fitting into specific methodologies within the given conceptual frameworks by evaluating first-rate criteria-referenced tools of very definite views on CMT?
I would appreciate it if you could answer these questions of paramount importance in the Second Language Acquisition setting. In doing so, I thank you for your valuable participation in this survey.
