object-place learning in birds
TRANSCRIPT
Blaisdell & SchroederObject Perception in the Pigeon
The pigeon sits in the operant box.The box is equipped with…
-a touchscreen-a food hopper
Every few seconds, an object appears on the screen.
To get food from the hopper, all the pigeon has to do is peck the object when it appears.
The faster the pigeon pecks the object, the sooner it will get fed.
Methods
Here are the objects:
Let’s refer to them as objects:A, B, C, and D.
Here is what the screen looks like before an object
appears.
The objects appear in a specific order that repeats.
After the pigeon has played the game with this repeating sequence, we change the order of some of the
objects, locations, or both.
For an example, go through the following slides and see if you notice the sequence. Pay attention to when
the sequence changes!

Did you notice the sequence change?
Good job!
The normal sequence was (from left to right):
A B
C D
A
B
C
D
We can also change only the location order:
A
C
B
D
The final sequence was switched to:
A C
B D
Or object order:
The normal sequence was (from left to right):
A B
C D
A

The final sequence was switched to:
Location order changed:A

C
D
Which change do you think will slow the pigeon downthe most?
A C
B D
Object order changed:
A
C
B
D
Both changed?
Location order changed:A
B
C
D
If, like humans, the pigeon binds object and location information together in perceptual memory,Then Both changed should be least disruptive!
A C

Object order changed:
A

Both changed?
Your contribution will help us achieve our goal:
To find out if birds, such as the pigeon, perceptually bind objects as do humans and other
primates.
This project will advance our knowledge of how birds see the world.
Do birds see the world the same way that we do?
