[JAVA] Response time of concatenated responses

  Hi Soan,

  Could you share your experiment with us? How to measure response times depends a bit on how you structure your response collection. Before I can advice you something I would need to know what you did.

  Thanks,

  Eduard

  Hi @Soan,

  I'm joining in the conversation as I had responded to the previous thread (https://forum.cogsci.nl/discussion/7909/sort-the-concatenated-response-and-compare-it-to-the-answer#latest). If you're referring to the same program, in principle you would just need to make sure that you include response3 in the list of variables included in the logger's output. The code did store each response separately:

  var myArray = new String()
  myArray =vars.concatenated.toString()
  myArray=myArray.split('')
  console.log(myArray)
  myArray=myArray.sort()
  console.log(myArray)
  
  // saves each individual response in a separate variable (incouding these in the logger if you want them regostered in the output)
  // !! This example does not include a logger; you'd have to add it to your task where appropriate
  vars.response1=myArray[0]
  vars.response2=myArray[1]
  vars.response3=myArray[2]
  
  // assenmbles the sorted array into a string variable
  // Add sorted_concatenaed to the logger if you want it saved
  vars.sorted_concatenated=myArray.toString()
  console.log ("Sorted response sequence: "+vars.sorted_concatenated)
  

  If you're referring to a different program, please provide further information or a simplified version of your task so that we can take a look

  Best,

  Fabrice (on holidays)

  Thank you so much!

  I have tried that and checked that the 'response3' recorded nicely.

  But I don't see its response time. How can I measure its response time? Thank you so much...!

  Hi Soan,

  in one of the comments of the code example Fab has written:

  // !! This example does not include a logger; you'd have to add it to your task where appropriate
  

  which is the reason the variable does not appear in the data file. Right?

  Thank you! I had put the variable 'response3' on the logger and checked the variable well on the spreadsheet. But there was no response time for the variable.

  I searched old posts, and found a way around it; putting an empty slide after the keyboard response and calculating the difference between the previous slide of the keyboard and the post slide.

  Thank you so much for helping me out!

  Could you please help me to calculate the response time?

  What I know: The response time of the first answer to each problem

  What I want to know: The total duration to enter all the three answers to each problem

  The participants press three keys to answer each problem. For example, 'abc', as exactly written on the code of Fabrice.).

  I tried to calculate the amount of time taken to enter the concatenated responses, using the difference between

  'time_problem' and 'time_final_RT.' However, there is barely any difference between them (285ms), which makes no sense.

  'response time_problem_solving_keyboard' is not the one that I am looking for because it only records the response time of the first response, for example, 'a.' How can you keep track of the duration of typing three answers? Below is a screenshot of my script. Thank you.

  

  (I referred to this post: https://forum.cogsci.nl/discussion/8024/using-time-variables-to-show-how-response-time-is-calculated. )

  'time_problem' and 'time_final_RT.' However, there is barely any difference between them (285ms), which makes no sense.

  This is because every time the loop is executed (for every iteration), the variables defined in the loop are overwritten. Specifically time_problem and time_final_RT.

  The easiest would be to have another variable and adding the time to push a button to the total RT. For that you need to initialize the total RT before the loop. Something like that:

  // initiliaze variable
  vars.total_RT = 0
  

  and in tracking_problem_solving :

  // add the time to press a key to the total time
  vars.total_RT = vars.total_RT + vars.current_RT
  

  Note, I don't see in the code how vars.current_RT is computed, but from your description of the situation it seems like you know how to do that. Let us know if that is still a problem
