[open] odd ball task problems: target occurs 2 and 3 x in a row with Sebastians visual ERP example

edited April 2013 in OpenSesame

This very well could be some error I am doing on my end but the experiment stops after 150 presentations of the non targets and targets. Also there are presentations of the target two or three times in a row. There is one easy fix I know I need to do in the script: I need to change the screen size to the correct size. Below is the bug error report:

I was wondering if I could just place the variables in a excel spreadsheet seperating the target/non target to ensure that the target is never seen twice in a row? Would it then be possible for me to place the spreadsheet in opensessame? I am not concerned with a random order as my goal is to establish baseline measures of auditory ERPS.

I was also wondering what changes I would need to to make if I was going to have five trials of 200 presentations with each trial having 20 targets?

Would I most likely get the same results if I continued with one trial, 1000 presentations and 200 targets at 750ms?

I realize you very busy but any suggestions would be very helpful.

Kind Regards,

AJ

    Sorry, I was able to get the experiment to work with the target never being presented twice in a row after putting in the correct screen size.

    Next task is to see if I can get the experiment and Emotiv EEG to communicate. I am going to use Advanced Visual Com Port and the examples in the forum to hopefully achieve this connection.

    would it require a huge modification to change this present experiment to a go no-go task? Hit the space bar every time a person sees the red square and not to hit the space bar when a the blue circle is presented? There would not need to be a change in current frequency of the presentations of targets vs nontargets. I would think I would just need to place the use of the keyboard in the correct place in the script.

    Thanks

    Perhaps previous forum posts on this topic would get you started. See, for example:

    Please let us know if it's not completely clear how to implement this in your situation.
