EEG_and_mouse_tracking

This repository holds the code used for running mouse-tracking and EEG experiment and analysing the data. The code was used for the exam project in Cognitive Neuroscience.

Experimental design

The participant is exposed to a object discrimination task, in which two stimulus objects are presented. Before each trial, the participant is instructed to press on a certain stimulus (for example “banana”). Three types of trials are presented:

1. A congruent trial, in which stimulus objects are colored congruently with their typical color (e.g., a yellow banana and a red apple).
2. An incongruent trial, in which the colors of stimulus object are switched (e.g., a yellow apple, and a red banana)
3. A neutral trial, in which the stimulus objects consist of achromatic line drawings of the stimulus objects.
