Displaying the CS response strength results for the three levels of CS-intensity in a single graph confirmed that
a. the rate of acquisition was unaffected by the intensity of the CS.
b. the asymptotic level of conditioning was the same for each level of CS intensity.
c. acquisition was complete after one trial with the high-intensity CS.
d. the change in CS response strength from one trial to the next was smaller in the earlier trials than in the later trials.
a. the rate of acquisition was unaffected by the intensity of the CS.
Answer feedback: Even though the CS response strength was still lower on the final trial for the low-intensity CS than for the other two intensities, with additional trials it would have eventually reached the same level of CS response strength obtained for the others. In other words, CS response strength approached the same asymptote regardless of CS intensity..
