Response Locked ERP

This Classical EEG experiment was replicated in order to show the robust signal from PsyPhy's amplifier. I designed the paradigm, built it using EventIDE, and managed the lab for 20 participants.
DESIGN
The design is simple, have four buttons corresponding to the participant button box we used that will light up randomly. Experimental loop consisted of 1000ms fixation screen viewing the buttons; 350-500ms stimuli screen that has an X appear in one of the four buttons; Response screen that waits for participant to press button or times out after 5000ms; Repeat.
This experiment including in depth instructions, a practice phase of four trials (one for each button), interactive feedback on their performance, five breaks, and a conclusion.
RESULTS
EEG data represented in an ERP is currently in development.
Motor Responses for EMG connected to forearms can be seen in image below. This displays the EMG for the left arm with a positive spike hen buttons 1/2 are pressed (on the left side of the box) and shows no difference in signal for button 3/4 on the right side of the box.
