It looks like you're new here. If you want to get involved, click one of these buttons!
Would there be any simple way to select the correct answer with an image? Preferably without using form.
Thank's and apologize my english.
am I assuming correctly that participants should click on one of the images to indicate their response?
If so, one option is to use the mousetrap_response item to define clickable areas on a sketchpad, that is, a rectangular area around each image. If a participant clicks on the corresponding area, this is recognized as a response and coded accordingly. You can also define which response is correct in the mousetrap_response item.
Mousetrap is a plugin that needs to be installed first (see here) (please be sure to install the development version in case you are using the most recent version of OpenSesame). The mousetrap_response item is documented here. Mousetrap also continuously tracks participants mouse movements (you can ignore the details there and unselect that feature if you are not interested in this data).
Add on: In new versions of OpenSesame and mousetrap, you can now also use named elements to define buttons (see steps 2 and 3a in the mousetrap_response documentation). Currently this only supports rectangle elements on sketchpads (we will add support for images later), so you would have to draw a rectangle around each image as the button border and name it.
Alternatively, you can directly use the ROI feature for mouse_response items that was introduced in OpenSesame 3.2.
Ty so much Pascal.
