If you are linking the technique to the intended purpose/why, you could write something like 'ultimately, this is intended to...', 'the writer does (insert effect) by using...'or 'This is designed to... '. If you are trying to link the intended purpose and effect you could write something like 'this may act on the readers' sense of...', 'consequently, readers may harbour a sense of...', 'in effect, readers may experience...', 'Henceforth, (insert emotion) may evoke readers towards...', ''in addition, (insert emotion) may be aroused in the readers', or 'subsequently, readers are invited to consider/asked to question/confronted with/subjected to'.
Hope this helps! All the best for tomorrow
EDIT: When explaining how readers are positioned to react, it's a good idea to use the word 'may' rather than assertive language. For author's intentions though, or direct effects, assertive language is perfectly fine.
