Press Button Until Tone

Download Synapse Experiment


example 1 abstract

This behavioral experiment is designed to test subject attention by having them press a button for a randomized time until a tone plays.

When the paradigm starts, enter a pre-trial phase in which the subject must fixate on a cue light for a set period. If the subject succeeds in fixating, move to the trial phase; if not, restart the pre-trial phase.

During the trial phase, the subject must press and hold a button for a randomized time until a tone plays. If the subject remains pressing the button until the tone is played, then it receives a reward. If the subject releases the button before the tone completes, then it fails and receives adverse stimulation.

After the trial phase the pre-trial phase begins again.
