Randomize trials in a number of ways: one level, two level, once per experiment or per participant group, and so forth.
When a trial uses two or more stimulus lists, items in the lists can be paired, unpaired, or crossed. Sublists are, of course, born randomized.
You can randomize elements within a trial: position of text, pictures or movies, color of text, and/or exposure duration.
For visual thresholds, predefine in SuperLab the exposure durations and then use rules to move to the next or previous level, contingent on the participant’s ability to perceive the stimulus.
Create lists for text, pictures, audio, movies, self-paced reading, or even event markers.
Apply any number of tags to individual items in the list. Divide your list into sublists, and even synchronize subsists belonging to different lists.
Parameters let you build more sophisticated experiments, e.g. create a “Counter” to add points earned or number of correct responses.
If you have previously coded, you know the tedium of implementing a moving window paradigm: create an array, fill it with new trials, and delete old ones. In SuperLab, you simply create a “Collection of Trials” parameter.
Build even more advanced experiments without learning to program or needing to type IF THEN ELSE statements. In SuperLab, you choose the criteria and actions from a menu so you can focus on the logic – not the syntax.
As promised: simple.
Simple as well.
A built-in “loop guard” feature prevents the dreaded infinite loop: when a repeated block results in no trials being presented, SuperLab moves to the next block automatically.
A response can be a key press, key release, typed text, or a non-response (go/no-go paradigm). Also supports voice key and external response pads.
Choose which blocks of trials are used in a group. All randomization options can be applied on a per group basis.
Attach tags to trials and change them at run-time to create contingent presentations. Tags are saved to data file to make analysis easier.
Provide feedback, repeat a trial, or update parameters based on a response, lack thereof, or reaction time.
Participants’ responses and RTs are saved in tab-delimited plain text files that can be imported into any software. Use our Data Viewer to merge them.
Create your experiment on either Mac OS or Windows, then run it on either Mac OS or Windows.
