17th February 2015 This is a PC-based program. We have made this program available so that other researchers can check what our training package looked like. We have no objection to others using it, provided attribution of the source is given. We cannot, however, provide any technical support, and we do not guarantee accuracy of the results. In particular, the reaction times obtained with this program are dependent on the computer processor and should be taken only as rough guides to relative difficulty of different tasks. Please note: this program will only work if you install its components exactly as stated in the instruction leaflet (see pdf in Files section), and if you have your screensize set to 1024 x 768. (And we cannot guarantee that it will work even then! We have found that a program that works fine on our systems may not work on other platforms, so sorry if that is the case). 6th February 2015. The training program was created in C++Builder4. We are trying to create a version that will be available to other users, but we have run into problems so far, so we regret to say that this material is not currently available. Files to run the program are on the Dropbox link. Data are stored in xls files starting with Z, identified by subject code, task and session. 30th May 2014 This copy of training program dates from November 2009. The vocabulary, paired associate and grammar learning programs are pretty straightforward; To run the program, you have to enter first a task code (select from list shown near bottom of the screen) Then a code number (any number should work) Then a session number (start with 1). The program should just run to completion. To do the memory experiment, you first select the option for memory span to establish the span. This has to be specified to start at session 3 (which is the first span length tested). If all items are responded to correctly it will proceed to the next span length. Otherwise it steps down to shorter length. The maximum length is 6. If that is reached, you need to end the program or it will crash. You can then do the memory game, using whatever span length the child achieved. This game looks for a Hebb effect by comparing repeated sequences with novel sequences. So when starting the memory game, you need to specify 'session' as the child's memory span.
