SSRTs can either be calculated:
- Using a Mean estimation (MRT - MSSD)
- Utilising the RT distribution of correct Go Trials in a to estimate the Stop-Signal Reaction Time.
Since the 2nd approach uses an integrative procedure that estimates the SSRT from the RT distribution using p(response | signal); in cases where p(response | signal) == 50%, both estimates should produce similar results.
