Problem
Given the hypothetical case of how a very noisy environment differentially affects male adults and female adults, or boys and girls. The areas you are assessing is their ability to finish reading comprehension task under those conditions. Your hypothesis is that female adults and girls will be less affected by high level noise than male adults and boys. In this case study example, if you provide a fully informed consent, you would need to include the expected findings within the informed consent form. As such, you might unintentionally influence the results - so you might add a statement that this is not a given, but what your hypothesizing. As an alternative option, you can opt to provide a limited informed consent, where you do not reveal what you expect to find within your informed consent. If you opt for this approach, you want to argue why it is okay to exclude this information from the consent form, focusing on how this might allow for more valid results to be obtained.
