Likert scale

I would like to run a grammaticality judgement task with a 4-point likert scale on Superlab. May I know what kind of keyboard I should buy?

I tried to open some files in other posts showing how an experiment would be run, but couldn’t see anything. Must I install Superlab first?

Thanks very much.

SuperLab is compatible with most keyboard types. In order to run the experiments, you will need to install SuperLab. You can download the 30 day demo from the link below.
