The aim of this lab report is to investigate whether the primary motor cortex (M1) is causally involved in mental rotation of Shepard figures (Shepard & Metzler, 1971) and also hands (Bode et al., 2007). Additionally, we will use the neural noise TMS approach to interrupt processing of M1 during a mental rotation task.
We will compare mean reaction times (RTs) for real TMS and sham TMS conditions for each experimental condition (Shepard figures and hands) using the relevant statistical tests. You will also need to write a full lab report (excluding the method section, which will be provide to you) on this hypothetical experiment.
This will comprise a title, abstract, introduction, results, discussion, and also references. The two papers below are require readings for the lab report. These two papers will give you a strong grounding in mental rotation research using TMS. Beyond these two papers, it will be up to you to decide what information to include in your introduction. Further, we have provide you with some further readings to get you start.
These are available on the Canvas website under the Assessments module. You are also encouraged to include other papers you may come across while researching on search engines such as the University of Melbourne Library, Google Scholar, or PubMed.Eisenegger, C., Herwig, U., & Jäncke, L. (2007).
