Question

A pigeon is confronted with two disks, one green, the other red. The bird receives food on a VI 20" schedule when it pecks the green disk, and on a VI 10" schedule when it pecks the red one. You
Predict that the bird will peck _________.

A) one disk about as often as at the other
B) the green disk almost exclusively
C) the green disk about twice as often as the red disk
D) the red disk about twice as often as the green disk

Answer 1

Answer:

A) one disk about as often as at the other

Explanation:

There's no indication which disk was placed first. Therefore, the outcome is random but of course one would be more often than the other.

Answer 2

Answer:

D. the red disk about twice as often as the green disk

Explanation:

I predict that the bird will peck that the red disk about twice as often as the green disk.

This is because it will take the VI 20" schedule twice of what it will take VI 10" schedule to deliver food to the pigeon.

Also, the pigeon will pick up the behavior that the VI 10" schedule delivers faster when it pecks on the red disk.
