[solved] Choice task multiple options
I am developing a multiple choice task in OpenSesame. Subjects are presented with a screen on which 6 cues are shown. Each of the cues corresponds to a certain keyboard key. Subjects should be able to select none or multiple (any number between 1 and 6) of the cues by pressing corresponding keyboard keys. After pressing the key corresponding to a certain cue, a box should appear around the cue. If then a different key is pressed, corresponding to a different cue, a box should appear around that respective cue as well. All keyboard responses should be logged. Subjects indicate by pressing space that they are finished making their selection (and they go to the next trial).
What would be the best approach to accomplish this? I read on the forum that it is not possible to have multiple keyboard inputs on one sketchpad. Therefore, i guess a staged approach (kind of tree diagram) might be the best? That first the screen with the cues (and no boxes) is shown. If key A is pressed, a next screen is shown with the cues and a box around cue A. Then if key B is pressed, a new screen is shown with the cues and boxes around cue A and B. Etc. Etc. This means I would have a tree that splits 6x5x4x3x2 times. Also, I have to make screens with cues and boxes around all different cues and all possible combinations. The logging of the keypresses would also become quite complicated. If this is the only or most appropriate approach, that is fine. However, if you think there is a more practical approach, please let me know.
