We will be exploring some of these differences in Unit 6. Each unit in this course has a review activity to check that you have followed some of the ideas in the unit. If you feel that you have done so, go on to the Review Activity now. Otherwise, read back over the unit before you do the Review Activity. Make a note of your answers and then compare notes with my comment.
Comprehensible language is vital to the language learning process.
Unlike spoken language, sign language has no grammar rules. You don't have to correct a baby's language for acquisition to occur. It's not necessary to be able to describe the rules of grammar to be a fluent speaker. Babies only say things that they have heard someone else say. Behaviourists say that we learn language by responding to stimuli, without any inborn idea of how to do it.
