A researcher is attempting to test the hypothesis that vibrotaction is important in the perception of fine or closely spaced texture. She uses a 10 Hz vibration stimulus applied to the skin for 7 minutes to adapt the Meissner corpuscle and a 250 Hz stimulus applied for 7 minutes to adapt the Pacinian corpuscle. What effect did adaptation of the Meissner corpuscle and the Pacinian corpuscle have on the ability to perceive texture, based on the chart below?
