INTENTIONAL CONDITION

Part 1 of 2

Your task in this experiment is to identify which
cartoon faces belong to doctors and which to 
policemen.

Please look closely at each cartoon face that you
are shown, and figure out how you can tell
whether the face is that of a policeman or a 
doctor. At first you will have to guess, but as we
go on, you will be able to tell just by looking at the
face.

You will be presented with faces one at a time, 
along with a picture of a policeman's uniform and
a picture of a doctor's uniform. Underneath these
uniforms will be written the key you should press
if you think the presented face goes with that 
uniform. 

For example, if you think the face is that of a
policeman, press the key written under the 
policeman's uniform.

After you make each decision, you will be told
whether you are right or wrong, and shown the
correct decision.

You will be asked to decide about 24 pictures in
this part of the experiment.

Press SPACE when you are ready to start.


Part 2 of 2

In this next part of the experiment, you will be
shown mores faces, and you will be asked to decide 
on the appropriate uniform, based on the doctors
and policemen you saw in the first part of the 
experiment.

In this part, you will not be told whether your 
answers are right or wrong.

There are about 130 decisions to make in this part
of the experiment. Remember to base your decisions
on the doctors and policemen you saw in the first
part of the experiment.

Press "b" when you are ready to start.

INCIDENTAL CONDITION

Part 1 of 2

This study concerns the recognition of people.
Pictures of cartoon men will be shown to you
one at a time.

Each time you are shown a picture, you
are asked to say whether or not you have
been shown that picture before in this experiment.

Press "Y" if you think you have, press "N" if 
you think you have not.

You are then asked to rate your confidence in 
the decision you have just made:

1 - Not confident
2 - Neither confident nor unconfident
3 - Confident 

As this part of the experiment continues, you
will begin to see many repetitions.

You will be asked to decide about 24 pictures in
this part of the experiment.

Press SPACE when you are ready to start.

Part 2 of 2

I'm sure you noticed that some of the cartoons
were of doctors and some were of policemen.
In this next part, you will be shown only the faces
of different men, and you will be asked to decide 
on the appropriate uniform, based on the doctors
and policemen you saw in the first part of the 
experiment.

The two uniforms, along with the keys you need
to press, will be shown on the screen. So, for
example, if you think a face belongs on the doctor's
uniform, then press the key corresponding to
the doctor's uniform (the key you need to press 
will be shown on the screen).

You will not be told whether your answers are
right or wrong.

There are about 130 decisions to make in this part
of the experiment. Remember to base your decisions
on the doctors and policemen you saw in the first
part of the experiment.

Press "b" when you are ready to start.
