[solved] Continuous Rating

  Hi @Sarah_

  
  

  As Eduard previously responded, you will need to use JavaScript to implement a slider or another fancy type of continuous rating. Perhaps it is easiest to draw a rating scale with a sketchpad item, ask participants to click on it with a mouse_response item and then determine the coordinates?

  
  

  Cheers,

  Dear @lvanderlinden ,

  thank you for your response. I asked the question again to ask whether there are any other ways beside a slider to collect continuous ratings.

  Is there a way in OSweb to collect ratings the way you suggested (mouse_response coordinates), but not only collect one rating per screen? I want to show an image and collect continuous responses on 10 separate questions.

  Cheers,

  Sarah

  Hi @Sarah_ ,

  
  

  I'll try to make a template for how to do this. It won't be a slider though, just lines (e.g. ranging from "completely disagree" to "completely agree") that participants can click on.

  
  

  Cheers,

  Hi @Sarah_ ,

  
  

  I hope the following example script can help you further. I implemented only three rating scales, but you should be able to increase the number of questions per screen.

  
  

  If you need any more personalized help, we can refer you to our paid support option.

  
  

  Cheers,

  Hi @lvanderlinden ,

  thank you for your help and the template! This helps a lot.

  My only question about it is if the click location (e.g. rating on the scales) is logged in this template? I see the logged variables in the template, but when I tested it in Jatos, the resulting data frame columns only said the following in both rows:

  clicked_response: none ; my_cursor_roi: line 3 ; question: none

  Thanks!

  Hi @Sarah_

  
  

  Oops, sorry about that. The logger item in the example was not logging the correct variables...

  
  

  If you tick "Log all variables" in the logger item all variables will be logged. If this makes your experiment too slow on OSWeb, you can manually add variables. The x coordinates per question are stored in the variables 'x1', 'x2', 'x3'.

  
  

  I uploaded the corrected version (logging all varialbes).

  
  

  Thanks for pointing this out and good luck with your experiment!

  Hey,

  thank you @lvanderlinden your template was also really helpful for me.

  But for me there ist one question left: Is there any possibility, that the participants don't have to do the rating by a mouse_click, but instead change the position of the rating icon with the LEFT and RIGHT keys on the tastatur and to log the choosen position?

  Cheers,

  Hi @strahel ,

  
  

  Could you perhaps upload the experiment that you have so far?

  Hi @strahel ,

  
  

  Me again. I think this script should work. Participants can use the arrow keys (left and right) to change the position of the cursor. To accept the final position, they can press enter. Then the next trial starts.

  
  

  Could you please check whether the script works in your browser? If not, perhaps the words "left" and "right" should be capitalized in the inline_javascript item.

  
  

  Cheers,
