Hello everyone, I am conducting a research, in this research I am investigating the TRF which is related to the semantic dissimilarity of the words in the sentence, in other words, my stimulus is the semantic dissimilarity, and my test is that two educational films I play the same content for two groups, and the only difference is that in one group, Mayer's principles were observed for the educational video, but not in the other group, and we want to know whether these principles have an effect on the cognitive load or not. The RF that is irrational for the group that watches the movie without principles, and its range increases, while the range is smaller in the group with principles, and also in other articles that I review TRF, the range of TRF is small. And also At zero time, there is a jump that is illogical, and I have checked various cases for this issue, including data pre-processing (for example, I have checked different frequency bands for filtering), or I have checked different fs But the same problems are repeated. Does anyone know where my problem is?
I can't add a photo to show you, does anyone know what I should do?
