multiple choice item
Hi all,
Was wondering what happens to the response variable if a participant clicks 'ok' without answering a multiple choice question: the output for a standard multiple choice item looks like this:
Maybe #maybe selected
no #nothing selected
No #No selected
The middle value: no, with small 'n' was a click on OK without having entered anything, so this seems to be the standard if participants do not reply, however it is very close to the 'No' with capital 'n', is there a way to change this? (for example to NA)
PS: this only happens when the multiple choice item is not set to immediately advance to the next item
PPS: I am still running open sesame 2.9 hesitant heisenberg, perhaps the behavior has changed in the updated versions

Hi Roelof,
That's correct. If no checkbox has been selected, the return value is 'no'. (And yes, this can be confusing if one of the options is also 'no'.) See also:
In cases in which this leads to ambiguity, there are some tricks to work around this. But in your case I wouldn't bother, because there is no ambiguity:
'No' != 'no'.Cheers,

Hi Sebastiaan,
That is true, however, the concern is that if I look back at the data in three weeks I will not remember which no is No or no, Eduard came up with a very simple idea which works smoothly:
if exp.get('response_1') == 'no':
exp.set('response_1', 'NA')
note this has to be put in 'run'
That's a very good point.
