2  Experimental paradigm

In PsychoPy

Runs

  • chunks of 5-10 minute length

  • one run - one start of the PsychoPy script

Start screen

  • The script should start by showing a welcome message or instruction reminder

  • It should be waiting for key “5” (scanner “trigger”)

  • This is needed to synchronize the fMRI signal acquisition with your paradigm

  • After the start screen, there should be a period of ca. 10 seconds of nothing happening; this is needed to discard initial artifacts

Subject responses

Subject keys: 1, 2, 3, 4, [], 6, 7, 8, 9

BIDS plugin2 for PsychoPy

Should be installed and enabled to save events (conditions and button presses) in a comprehensive and standardized manner

This will also make our data analysis easier
