You simply need to run two <likert>s in sequence. See e.g. http://www.millisecond.com/forums/Topic3055.aspx#3055. Stuff like this has been discussed many times. In case you need more example, a search should turn some up.
Hi,
Is it possible to change a Likert scale in the same trial? I'm hoping to have participants rate images on two dimensions, one after the other. I set up the first scale using <likert> but I don't know how to change the scale (from 1-5 to $1 - $15) mid-trial. Any ideas?
Thanks!
