Answer:The technique use in this study is referred to as a double blind
Explanation:
A double blind study is the one that both participants and experimenters or researchers are not made aware who is given a certain treatment.
In double blind researchers will not know if what they are receiving is part of the test itself as they interact with participants or they are receiving a placebo.
This process is useful to eliminate and avoid bias results.
