Response bias in below-chance performance: Computation of the parametric measure β

Psychological Bulletin, 106(2):338-340.

We argue that conceptual problems arise with the parametric measure β when above- and below-chance data are aggregated or compared. Depending on the interpretation of β as a likelihood-ratio measure or an indicator of strictness or bias toward signal or noise, the original formula for β should be retained or modified. The response bias measure β can be retained only if it is interpreted as a likelihood-ratio measure. If it is interpreted as an indicator of strictness or bias toward signal or noise, the original formula has to be modified. One possible modified formula is suggested here.
