Zep comes with a set of ready-made experiment scripts. We have grouped them by paradigm. See the list below. How to install and run an experiment is explained in Installing an Experiment. How to change the design, structure or other details of a typical experiment is explained in the How-tos.
Experiment scripts are packaged as ZIP file. There's one ZIP file for each individual experiment.1) Some experiments come in different flavors. You have the base experiment (the generic version), then there can be alternative versions, extended versions and derived versions.
This is the vanilla or base version of the experiment. For most experiment types no other flavors are available. These experiment scripts use a within-subjects design. The global structure of most scripts is:
An alternative version of an experiment is basically the same as its generic version, but it is either a different implementation of the same thing or it implements a slightly different procedure. If the generic version's experiment folder is called
foobar then the first alternative version is called
foobar_a1. The second alternative if any is called
foobar_a2, and so on.
An extended version of an experiment is also basically the same as its generic version, but it includes additions such as the definition of participant groups or shuffling stimulus items according to certain criteria, things like that. If the generic version's experiment folder is called
foobar then the first extended version is called
foobar_x1. The second is called
foobar_x2, and so on.
A derived or specialized version of an experiment is based on its generic version so it implements more or less the same paradigm, but other than that it is a different kind of experiment.
