Lecture 8: 2013/01/31
Questions of the day:
1) Can we use reinforcement principles to change another’s personality?
2) Can we change another person’s personality with operant conditioning?
3) What can the training of exotic animals teach us about operant conditioning?

- The central lesson I learned from exotic animal trainers is that I should reward behavior I like and
ignore behavior I don’t. After all, you don’t get a sea lion to balance a ball on the end of this nose by
nagging. The same goes for the American husband
- Need to know that how any reaction you give can be reinforcing. Alert to tone of voice, posture,
- SHAPING: I was using what trainers call “Approximations,” rewarding the small steps toward
learning a whole new behavior. You can’t expect a baboon to learn to flip on command in one session,
just as you can’t expect an American husband to begin regularly picking up his dirty socks by praising
him once for picking up a single sock. With the baboon you first reward a hop, then a bigger hop, then
an even bigger hop. With Scott the husband, I began to praise every small act every time: If he drove
just a mile an hour slower, tossed one pair of shorts into the hamper, or was on time for anything.
Training incompatible behaviors (To treat undesirable behavior)
- “Taught African crested cranes to stop landing on his head and shoulders. He did this by training the
leggy birds to land on mats on the ground.”
- “Rather than teach the cranes to stop landing on him, the trainer taught the birds something else, a
behavior that would make the undesirable behavior impossible.”
Any reaction can be reinforcing
- I followed the students to SeaWorld San Diego, where a dolphin trainer introduced me to least
reinforcing scenario (L.R.S). When a dolphin does something wrong, the trainer doesn’t respond in
any way. He stands still for a few beats, careful not to look at the dolphin, and then returns to work.
The idea is that any response, positive or negative, fuels a behavior. If a behavior provokes no response,
it typically dies away.
- Number one problem that we have as parents is we don’t realize that any attention to their children can
- “After 2 years of exotic animal training my marriage is far smoother, my husband much easier to love.
I used to take his faults personally; his dirty clothes on the floor were an affront, a symbol of how he didn’t care enough about me. But thinking of my husband as an exotic species gave me the distance I
needed to consider our differences more objectively.”
Everything is not trainable
- I adopted he trainers’ motto: “It’s never the animal’s fault.” When my training attempts failed, I didn’t
blame Scott. Rather, I brainstormed new strategies, thought up more incompatible behavior and used
smaller approximations. I dissected my own behavior, considered how my actions might inadvertently
fuel his. I also accepted that some behaviors were too entrenched, too instinctive to train away. You
can’t stop a badger from digging, and you can’t stop my husband from losing his wallet and keys.”

Did Scott ever figure it out?
- “When the training techniques worked so beautifully, I couldn’t resist telling my husband what I was
up to. He wasn’t offended, just amused. As I explained the techniques and
