Estimating the difference limen in 2AFC tasks: Pitfalls and improved estimators

R Ulrich, D Vorberg - Attention, Perception, & Psychophysics, 2009 - Springer
Discrimination performance is often assessed by measuring the difference limen (DL; or just
noticeable difference) in a two-alternative forced choice (2AFC) task. Here, we show that the …
