DirectRT does not have a feature that is a direct parallel of the ranking item in MediaLab. However, DirectRT does have a lot of features that could be used to create a ranking of different stimuli. For example, you could tell DirectRT to require multiple keypresses for a single trial to have participants press keys associated with certain stimuli in a particular order like most preferred to least preferred; see this section of the DirectRT manual for more information about this feature: http://www.empirisoft.com/directrt/h...keypresses.htm.
I would be more than happy to answer any follow up questions you may have. Just post them here or email me at support@empirisoft.com
