Relationship between signal detection theory and drift-diffusion model?

When calculate signal detection metrics (e.g. sensitivity) from 2-alternative false choice task behavior data, we assume that the subject is internally comparing a variable to a threshold: if it...

Is it possible to use two-alternative (not two-interval) force choice task to measure target visibility map in humans?

Hi, My recent project requires me to measure visibility map in humans. Basically we need to present a target briefly (100-200 ms) at various retinal eccentricity and use signal detection theory...

What are the state-of-art (in 2018) methods for automatic correction of ocular and muscular artifacts based on ICA in the EEG?

I am looking for an automatic artifact rejection based on ICA for EEG data. It seems that many people use ADJUST, but based on my experience, it does not recognize muscle artifact very well.
