Observing the context, it may be correct to assert that:

[…] specific theories of the nature of language may provide the basis for a particular teaching method, other methods derive primarily from a theory of language learning. A learning theory underlying an approach or method responds to two questions: (a) What are the psycholinguistic and the cognitive processes involved in language learning? and (b) What are the conditions that need to be met in order for these learning processes to be activated? Learning theories associated with a method at the level of approach may emphasize either one or both of these dimensions. Process-oriented theories build on learning processes, such as habit formation, induction, inferencing, hypothesis testing, and generalization. Condition-oriented theories emphasize the nature of the human and physical context in which language learning takes place.
