  Hi Nicolas,

  A visual-search paradigm, such as the Treisman & Gelade one, requires a bit of Python scripting. You won't be able to implement it using only a sketchpad, or at least not in an efficient way. I would recommend taking a look at these discussions:

  Hi Sebastiaan,

  scripting/programming is not my thing, so I created each pic myself and imported them just like the catfaces of the tutorial

  and it works

  still, each time I launch the test, it generates a csv file. Is it possible to accumulate the results from different subjects into one single datasheet ?

  and is it possible to decide what parameters should appear in the csv file ? There are too many columns for my needs.

  another thing is in the variable fname, I don't have access to the file list, I need to write each file name myself (on the video tutorial it seems the file names appear automatically in the fname column after they have been selected in the sketchpad ?)

  thank you
  Nicolas

  Not directly, but you can merge the data files with DataMerger:

  and is it possible to decide what parameters should appear in the csv file ? There are too many columns for my needs.

  Yes, you can disable the 'Automatically detect and log all variables' option in the logger, and then select only the variables that you need.

  another thing is in the variable fname, I don't have access to the file list, I need to write each file name myself

  Do you mean the name of the logfile? I see that it's indeed not logged automatically. But you can easily do this by adding logfile as a custom variable in the logger. (The variable exists, it's just not automatically picked up by the logger.)

  Cheers!
