Hi,
I am currently working on a new matching task.
First, an instruction appears on the screen "Ex : Red same as ?". Then three samples appear on the bottom of the screen. The participant has to drag one of the three samples into the black square with the question mark.
When the sample is dropped, we ask the participant to confirm is response : the instruction appears on the screen with the sample he previously selected. The participant can choose to try again (pressing the "start again" button reset all the stimuli to where they were before the sample was dropped) or to validate his answer (which launches a feedback trial).
At the moment, I only implemented the "drag and drop" feature for the "match_sample" element. But I am already facing different issues :
- during the trial "correctselection" all the stimuli become blurry
- if I press "start again" in the second phase of the experiment, the dropped sample doesn't go back to its previous position.
Could you please help me?
Thanks a lot,
Lucie
