From psrcg at csv.warwick.ac.uk Tue Feb 20 14:29:45 2001 From: psrcg at csv.warwick.ac.uk (Gaynor Evans) Date: Tue, 20 Feb 2001 14:29:45 -0000 Subject: Adaptation of an n-back task Message-ID: Hello I am currently trying to create an n-back memory task in e-prime, where the subject will be presented with a series of letters and they must decided whether each letter is the same or different to the letter they saw three letters previously. As far as my understanding goes, the only way in which I can achieve this is by having a separate e-prime experiment for each subject. Does anyone know of a more economical way of doing this? Thanks for your time Gaynor Evans PhD student Department of Psychology University of Warwick Coventry West Midlands UK CV4 7AL From beta at pstnet.com Thu Feb 22 15:52:24 2001 From: beta at pstnet.com (Beta) Date: Thu, 22 Feb 2001 10:52:24 -0500 Subject: Adaptation of an n-back task Message-ID: Dear Gaynor: The n-Back task can be accomplished in one experiment by using E-Basic script. It is not necessary to create separate experiments for each subject. In the current beta, the n-Back is done by creating a Queue data structure to store and retrieve exemplars. The Queue can either be created as an array or as a user-defined type. The Queue structure that will work best for you will likely be dependent on the selection constraints you have set for your specific n-Back paradigm. If you would like to contact E-Prime technical support via e-mail at beta at pstnet.com, we would be happy to offer you a sample experiment to illustrate how the Queue structure is created and used via E-Basic script. At that time, a brief explanation of the constraints of your experiment would help us point you in the right direction. We look forward to hearing from you.
