I'm using the Taylor Aggression Paradigm in my research at the moment and it requires a simple competitive reaction time task in which participants indicate when a stimulus in the centre of the screen changes colour (e.g. a blue square become red), and are given immediate feedback on their performance.
The nature of the stimulus isn't really important, as long as some sort of obvious change occurs.
I was planning to create this task using E-Prime (which I'm entirely new to), but does anyone have a similar task already set up that I could maybe 'recycle'? Or if not, any tips for setting one up in E-Prime?
Have you hit up the eprime message boards yet? (https://psychologysoftwaretools.zendesk.com/forums) You may be able to find a similar task posted there. At the very least you can find some examples to build upon. Eprime is the dominate presentation software right now. For the long term it is probably worth grinding it out and developing the task so that you learn the program. It is a little it funky at first, but gets intuitive after a while.
Hey Brian, thanks for the tip! I've had a look on the message boards,and haven't found anything close enough to what I need, which I think is probably a sign that I should just muck in and put a test together myself.
Thanks for your advice!
As long as your feedback is just correct/incorrect that task won't be that hard to make. If you need to do some sort of calculation to give a percentage of correct trials it gets harder. Good luck!
Have you checked out PEBL? It's a (free!) programming language and software similar to that used in E-Prime, but there is a preloaded battery of tests. It's easy to alter the individual tests, too. I'm pretty positive the test you're looking for is part of their preprogrammed battery. You would need to make sure the computer you're doing the assessment on has PEBL downloaded on it. Here is the site: http://pebl.sourceforge.net/battery.html
Hi Zara,
I would recommend Psychopy, a free and easy-to-learn software to programming reaction time experiments. I could help you starting with you first experiment by creating a simple-RT experiment with a visual stimulus. From this point, you may start changing your program by changing parameters (e.g., visual vs. auditory target, interstimulus-intervals, response modality, RT measurement, and so on).
www.psychopy,org
The tutorial does also include a simple RT experiment, and there are some tutorial on youtube, which may be interesting for you.

Zara, I'm replying late so you might have already found a solution among the other good suggestions here, but in case it helps...
It is often easiest to modify an existing script. I think others have developed e-prime versions of the Taylor aggression paradigm using e-prime and might be willing to share their scripts (e.g., http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2759362/ )
If not, there are other E-prime reaction-time task scripts available at:
http://step.psy.cmu.edu/scripts/
and a good tutorial video for setting up a basic Stroop-type task at:
http://abacus.bates.edu/~tkahan/eprime.htm
When modifying tasks in E-prime, it helps to change just one parameter at a time, do a test run, and check the data output.
Good luck!

Hi everyone,
Thanks so much for your responses. I managed to find a test that fit perfectly with my requirements - Brad Bushman and Scott Saults have developed excellent software to run it consistently. They were kind enough to share it with me for my data collection!
If anyone requires a similar programme, I would suggest contacting them. They were hugely helpful.
Thanks again for all your advice!
