1. Email address and name fields need to be longer.
2. Is it clear that we need one or more of email and phone?

One users gaze went back up to the 'Select all that apply' text at this point. We were able to ask him about this and he confirmed that he wanted to check whether he was supposed to be selecting multiple options or not.

In this and other research we've observed that some users continue to click on the control rather than the grey box.

We tested an alternate design alongside this one, with larger controls. The users (all high computer confidence) were very slightly faster at clicking the controls (as per Fitts Law).

Equivalent testing on GOV.UK Verify with low confidence users shows the speed difference is much more pronounced.
