Using sliders in experiments

Hi Saskia,

I am not aware of a slider option yet. Alternatively, you could try and use the "show rectangle" command and create lots of thin rectangles (the amount of options you want to give the participant) in a line from the minimum to the maximum rating you would like, e.g. 1 to 10 you would need 10 rectangles and then you can use "readmouse" command and "UNDER_MOUSE" variable to get the chosen point on the scale.

readmouse l 1 100000 range 1 10
set $x UNDER_MOUSE

If you create the rectangles as the first thing in your display in the task, then you have the display numbers in accordance with the rating scale numbers you want to know without having to subtract any number in order to get the correct chosen scale rating.
