Mishkin et al.(1983) trained rhesus monkeys to do two different tasks.One task was called a landmark task, which required the monkeys to remember the location of an event, and the other task was called an object task, which required the monkeys to learn a particular object.What did they discover?
A)Rhesus monkeys were excellent at the landmark task, but poor at the object task.
B)Lesioning of the inferotemporal cortex resulted in impaired performance on the landmark task.
C)Lesioning of the frontal eye fields resulted in a decline in all performance.
D)Lesioning of the inferotemporal cortex resulted in impaired performance on the object task.

Mishkin et al. (1983) discovered that lesioning of the inferotemporal cortex resulted in impaired performance on the object task, suggesting that this brain region is specifically involved in object recognition and memory. There is no indication in the study that rhesus monkeys were better at one task versus the other, nor is there mention of lesioning of the frontal eye fields affecting performance.
