I am a master student in psychology in the US. I performed a study in which the participants had to read a story and should recall it afterwards.
Now I am writing a manuscript where I only analyze parts of the participants’ responses to answer my research questions. This puts me in a dilemma: Should I explain the whole story stimulus in my paper or just focus on the parts that I analyzed?
My supervisor suggested that I should not mention the unanalyzed parts of the story at all because that will distract readers and take away the focus of the paper. However, I'm thinking what if this paper is published and someone ask for the stimuli to replicate the study, and then find out that the stimuli is different from the way I presented in the paper. It’s like I’m hiding something from them. I worry this may lead to a retraction of the my publication. I’m very new to academia and my supervisor sometimes is not very on top of things, I don't think he cares much about what I do. So I want to make sure I do the right thing and ask for your advice.
