In the research of Jenkins and Harrison,one group of pigeons received presence-absence training--a 1000 Hz tone was an S⁺ and the absence of a tone was an S-.In a generalization test along the dimension of tone frequency,this group produced
A)typical generalization gradients with peaks at 1000 Hz
B)extremely narrow generalization gradients
C)flat generalization gradients
D)no generalization to other tones

The presence of a 1000 Hz tone as a conditioned stimulus (S+) and the absence of a tone as a conditioned stimulus (S-) would lead pigeons to associate the specific 1000 Hz tone with a certain response. In a generalization test along the dimension of tone frequency, this would result in typical generalization gradients with peaks at 1000 Hz, as the pigeons would most strongly respond to the frequency they were trained on, with responses decreasing as the frequency moves away from 1000 Hz.
