Multiple mouse response collection

Hi!!
as part of an experiment, I'm trying to create a choice task that will present participants with 16 different images of food, and they will be asked to choose 4 out of the 16 by clicking on the images, and will be given 10 seconds to do so. So far I've been able to create a form base with 16 image buttons, but as soon as I click on one of them, the experiment moves on to the next task. What do I need to add in order to allow the participants to click 4 image buttons before the experiment moves on?
Also- I would like the participants to be able to see that they clicked on an image, for example- the image could turn darker or become outlined after it's been clicked on. Is this possible?

Thank you,
Tzipi

Hi Tzipi,

What do I need to add in order to allow the participants to click 4 image buttons before the experiment moves on?

There are a few solutions. The simplest ones are:

1. Repeat the form 4 times; or
2. Use checkbox widgets with image widgets next to it.

Also- I would like the participants to be able to see that they clicked on an image, for example- the image could turn darker or become outlined after it's been clicked on. Is this possible?

The checkboxes would give you that, although it's perhaps not as pretty as you'd like. If neither of the solutions above suffices, then you'll probably have to use a bit of Python scripting.

Cheers!
