What are the main hypotheses of James Asher about learning second languages that are embodied in the Total Physical Response method?

1 grammar and vocabulary are taught inductively

2 the brain is naturally predisposed to learn language through listening

3 pronunciation is taught from the beginning, often by students working in language laboratories on discriminating between members of minimal pairs

4 teachers want their students to be able to use the target language communicatively

5 language forms do not occur by themselves; they occur most naturally within a context
