Hi All,

I am trying to combine a textbox response with a mouse-click response. For the former, participants should enter two earlier displayed digits (e.g., 7 and 9). For the latter, participants should press on one of several simultaneously presented shapes to indicate the colour of a target. A similar issue was raised in a previous forum post (https://www.millisecond.com/forums/Topic14994.aspx) from 8 years ago. Hence, I was wondering whether there would be a more straightforward way of doing so.

My current trial looks as follows:

/stimulustimes = [0 = clearscreen; 1 = fixation; 150 = clearscreen; 151 = t, d1, d2 , dig1, dig2; 350 = clearscreen; 600 = shape1, shape2, shape3, shape4, shape5, shape6, shape7, shape8]
/ correctresponse = (values.cresp)
/ inputdevice = mouse
/ validresponse = (shape1,shape2,shape3,shape4,shape5,shape6,shape7,shape8)
</trial>

Now, I would like to add the textbox entry before the shape selection screen. Ideally, I would want to avoid switching to another trial. Is this possible?

All the best,
Lukas

No, you'll need two trials. An <openended> for the textbox response, followed by the shape selection <trial>.

Thanks for your response. When trying to set this up, two follow-up questions arose:

a) Can the opendeded trial be followed by the 2nd response type automatically? The following code cannot be the way to do this:

<block 250ms>
/ trials = [1 = trial200; 2 = res2; 3 = trial200; 4 = res2; ...]
</block>

b) The correct response for the textbox should be a combination of the two presented digits. For instance, when 1 and 9 were presented I want the correct response to be 19. With the following code I have only managed to get both answer options to be correct, or the added value to the the correct response:

/ mask = positiveinteger
/ correctresponse = (values.dig1,values.dig2)

// OR

/ correctreponse = (valuesdig1 + values.dig2)

Re. a): You can /branch from the <openended> to the follow-up <trial>.
Re. b): You'll want to do

/ ontrialbegin = [values.correctanswer = concat(values.dig1, values.dig2);]

with

/ correctresponse = (values.correctanswer)

Order matters. You're "combining" digits BEFORE you have selected digits in the given round. You need to combine them AFTER.

Here

/ branch = [if(trial.trialPractice.correct == 1 || trial.trialPractice.correct == 0)trial.colorResponse]

it's not a <trial> element. It's an <openended>.

Here, these no longer make sense. Those aren't your response options anymore. You're now using objects called "shape1" to "shape8"
