Doubt with loops and sequences
I have a question related to the loops. I’m a beginner using OpenSesame so, to make this clear, I firstly explain what I want to see once the experiment is running. I have short stories divided into different sentences. I want each sentence to appear on a separate screen. The experimental subject will read each sentence and press space bar once the sentence has been read. Finally, the stories will be followed by a comprehension question. Importantly, the stories contain different number of sentences (min. 2 sentences and max. 5 sentences), but I will always have the first sentence (context sentence) and the target sentence. However, if the story contains more than two sentences,I will add more context sentence in the middle.
Therefore, I created an excel file with several columns. These columns are called: Context_1; Context_2; Context_3; Context_4; Target. The thing is that the columns Context_1 and Target always contain sentences, but the other columns are filled or not depending on the length of the story. When I was creating the experiment, I had the intention of creating a loop with a sequence containing several sketchpads + keyboard responses corresponding to the different columns (i.e., Context_1, Context_2, etc). The problem is that when I’m running the experiment, a black screen appears for cells that do not contain information and I have to press space bar to continue up to the comprehension question. My question is: Is there a way to say that cells in the excel file which do not contain information should be skipped? Or maybe should I reconsider the way I wanted to build my experiment?
Thank you so much!
