Quick Picture Reaction Problem
My experiment includes picture shows. But I need to show the pictures in a very short time like 250 ms. And I will take reaction during the picture show. My experiment structure is basically "fixation-picture-response tool-logger tool". Picture duration is 0 and response duration is 245 ms. Also I set the correct response variables and allowed response variables. However, correct datas are always "0" and response_experiment datas are always "none". I can't understand why the problem is the participants or the program or my computer.
All the best,
