This part of the tutorial examines how the parameters below changes the psychometric function, chronometric function (mean RT), and reward outcome in a DDM with choice bias.

Psychometric

Probability of making the rightward choice as a function of signed coherence;

Chronometric

Mean reaction time for leftward and rightward saccades as a function of signed coherence;

Parameters	Performance	Outcome Accuracy Mean RT Reward/Trial Reward Rate
	Sign of Coh For "%choice" plot For "RT" plot + rightward motion right choice (rightward saccade) - leftward motion left choice (leftward saccade)
