This how-to guides you through a test session using ZEP at the ILS Labs. It assumes you have completely prepared your experiment – including the replacement of the example stimuli with your own. Step 1 and 2 should only be done when running your experiment for the first time. Step 3 to 7 should be repeated…

When using ZEP, you can use a BeexyBox buttons box to measure participant responses and response times. Most ZEP 2 experiment templates already have the necessary code to use these button boxes. However, not all ZEP 1 templates come with this support out of the box, so you’ll need to add it yourself. This page…

In this how-to, we will discuss how to add different groups with different stimuli for each group to an existing (basic) experiment. This guide assumes that you are familiar with latin square and other methods and thus focuses on the implementation of groups in ZEP. Furthermore, this guide only looks at the actual test items….

Introduction Using markers during electroencephalography (EEG) helps to identify specific events in your data. When analyzing data the markers become crucial for synchronizing epochs or identify responses. It is of paramount importance that these markers are very precise; any jitter reduces the quality of your data. The accuracy of markers is of less importance. Markers…

The button boxes as used in the lab are in fact tiny computers themselves, which try to reason with the lab computers. Sometimes, something goes wrong in their communication and the button box thinks it can govern itself. Usually, it is enough to unplug the USB cable from both the button box and the computer,…
