recall list data misplaced (case 1747)

[bstewart]

Hello,

I have created a questionnaire in which I use the "recall list" variable type, but there is a problem with data being misplaced in the CSV files. Details of questionnaire are as follows: participants are told to recall all that they remember of 4 types of cars. Each car name is presented to them, and they are asked to recall what they remember. And, they are told, "After you do not remember anymore attributes, you can press the "Esc" key in the upper left corner to move on to the next car. After 3 minutes, you will be automatically moved onto the next car whether you are finished or not." So, each car is presented in a random order using the randomize within feature set to 1 for each item, the n parameter is set to 12 (there were 12 attributes), and the duration parameter was set to 180 seconds. The write data and the RT options were checked for each item.

The "by questionnaire" CSV file is fine until the "Recall" questionnaire. At that point, responses start to be put into the questionnaires that followed the Recall questionnaire. This does not always occur, but it appears to do so, perhaps, after a participant has used the escape key, but I am unsure. Please see attached file for an example of this data misplacement. The problem begins on column DA.

Not seeing the attachment here. Could you also include a copy of the que and let me know what version of MediaLab you are using? i.e., 200x.x.x?

Here are the requested files. We are using ml2008.1.22.

Brandon,

I just ran through your que a few times with the duration values set to 10 seconds instead of 180. Each time, I would do a combination of responses--sometimes pressing escape to end the recall list early, sometimes letting the time pass, and other times, answering all 12 for a given item. In these tests, the data did not fail to write--everything looked ok.

I'm not sure if the greater context of your experiment might be having an impact though. Can you try running your que (the one you attached) in a similar manner and see if you can get it to replicate the result? If not, we may need to look at what precedes or follows this questionnaire.

My other other question (sorry, forgot)--is what you found the same in the case of every data file--i.e., the .txt, .csv, and spss .sav files--and in both the byVariable and byQuestionnaire folders?

And one last thought--in case it's a possible cause, you have an earlier release of v2008. If you are able to reproduce the problem and I can't--it might help to update to the final release of v2008 (v2008.1.33) found at www.empirisoft.com/download_old.aspx.

I do get this problem in both the CSV and SPSS files for byQue, and byVariable (see attached zip file Au2010 NC...).

I also have tried to systematically replicate the problem using the Recall.que file in between the two questionnaires that it follows and precedes in the full experiment. However, I have not been able to replicate the problem using 30 different variations of responses (see attached zip file Au2010 test).

I will now try it with the updated final release of v2008.
