New paper by Mol­ly Hen­ry: Amu­sia diag­no­sis should bet­ter rely on sig­nal detec­tion the­o­ry

Sig­nal detec­tion the­o­ry – what helps pre­vent­ing mis­di­ag­noses and false pos­i­tives in gen­er­al can’t be bad for diag­nos­ing Amu­sia either, one would think. Our very own Mol­ly Hen­ry and her for­mer super­vi­sor Devin McAuley now demon­strate in a just-accept­ed paper

Fail­ure to apply sig­nal detec­tion the­o­ry to the Mon­tre­al Bat­tery of Eval­u­a­tion of Amu­sia may mis­di­ag­nose amu­sia

in Music Per­cep­tion that this is indeed the case:

They show that analy­ses based on con­fi­dence rat­ings and ROC-curves out­per­forms sim­ple per­cent­age cor­rect in diag­nos­ing Amu­sia.

Here is the abstract, and watch out for the full paper to appear soon:

This arti­cle con­sid­ers a sig­nal detec­tion the­o­ry (SDT) approach to eval­u­a­tion of per­for­mance on the Mon­tre­al Bat­tery of Eval­u­a­tion of Amu­sia (MBEA).
