I am a 2-grade psychology student.Recently, I am doing a research using n-back task with HDDM model to investigate working memory updating.However,aftering reading some papers about working memory updating,I am confuse about which paeameter could truly stand for the updating ability.the error rate ? RT? d'?
I'm in extreme confusion, can you recommend me some useful papers?
To be honest, these are questions that you should address with your supervisor. The n-back task is not optimal for isolating updating, because a lot of things are happening at the same time when you have to update the target in WM (e.g., you also have to remove the previous target, etc.). Yoav Kessler has developed a more elaborate version, called the "reference-back task", which can disentangle a number of processes related to updating working memory content.
