I need help regarding the analysis of EEG continuous data. Briefly, the study aims to explore the relationship between brain processes and performance on a neuropsychological test and if this test is able to detect differences in participants’ cognitive status. The test includes 21 stimuli (e.g everyday documents) and 42 related questions.
Can anyone help me clarify which steps and statistical analysis should I use? After studying the relevant litterarure, I concluded that synchronisation analysis suits very well with the study’s aims. It will help clarify which pairs of electrods were activated as well as the relative energy of such activity during the compeltion of the whole task and during the completion of each item. If this is correct, then what should be the next step?
I think, the next step is to check which electrods pairs contibute the most to total scores and scores on each item. Then, to check if there are differences in synchronisation for right and wrong responses. So, is my thinking correct? and if so what statistical analysis should I use?
Thank you very much in advance.
