Generalization testing often includes multiple presentations of the entire range of generalization stimuli under nonreinforcement,
while the originally trained stimulus is presented under reinforcement (i.e., steady-state testing; see Blough,
1976). This can provide an opportunity for further discrimination learning during test (the S+ versus the entire range of nonreinforced
generalization stimuli). To evaluate this possibility, we compared the shape of the gradient on the first test block
with the average over the six test blocks (we opted for this average, because it is an often used method to report gradients
in generalization research, cf. Lissek et al., 2008, 2010). We expected a sharper gradient on the averages over blocks than on
the first test block alone.
