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
