  Hi,

  Could you perhaps provide us with some more information, for example by sharing the experimental script or making a screenshot of your experimental overview? And by making a screenshot of your output table?

  To upload your experiment you could do the following:

  • Open the "General properties" tab, click "Script editor" and copy the whole script,
  • go to http://pastbin.com, upload your script there (simply paste and submit)
  • and provide us with the resulting link in your forum post.

  Best,

  Lotje

  Hi,

  If you're looking for the response times per trial, you should use the variable 'response_time', which is never undefined.

  The variable 'avg_rt' contains the average response time of all previous responses (until you reset the variable) and could be used for providing feedback, for example at the end of a block.
  The reason that in your experiment this variable gets the value 'undefined' after an incorrect response is because you reset the average by the feedback item, which is only ran when 'correct = 0'.

  Thus, I would advise you to use the variabe 'response_time' for your analyses.

  Does that help?

  Best,

  Lotje
