DDM trials generation with fixed post-decision accumulation time

Description

This function generates trials using the Drift Diffusion Model. Additional evidence is accumulated for a fixed time after the decision boundary has been reached. Note: here, decision boundaries are a and -a and starting point is equal to a*z.

Usage

DDM_with_confidence_slow(v, a, ter, z, ntrials, s, dt, t2time, postdriftmod)

Arguments

v	Drift rate
a	Decision boundary, evidence at t = 0 is equal to a*z. Decision boundaries are a and -a
ter	Non-decision time
z	Starting point bias in evidence. For unbiased DDM, use z = 0
ntrials	Number of DDM trials to generate
s	Scaling parameter
dt	Time step size
t2time	Post-decision accumulation time
postdriftmod	V-ratio. If equal to 1, post-decision drift rate is equal to decision drift rate
