Card 15 / 54: In one study of blindsight, monkeys had ablation of the left striate cortex and the splenium of the corpus callosum. In the first experiment, monkeys responded to a light coming on by touching the location of the light on a monitor. In the second experiment, monkeys did the same task, but also touched a specified location when they believed that no light came on (blank trials). The findings were:
A)
monkeys identified lights coming on in both visual fields in both experiments
B)
monkeys identified lights coming on only in the left visual field in both experiments
C)
monkeys identified lights coming on in both visual fields in the second experiment, but only in the left visual field in the first experiment
D)
monkeys identified lights coming on in both visual fields in the first experiment, but only in the left visual field in the second experiment
Answer:
D) monkeys identified lights coming on in both visual fields in the first experiment, but only in the left visual field in the second experiment
