Suppose one trains a dog to come running for food when one whistles a 60 db whistle and also trains the same dog to not come running when one whistles a 70 db whistle. according to the peak-shift effect, which whistle would then lead to the dog's fastest running?
a) 50db
b) 60db
c) 70db
d) 80db

(a) 50 dB
