• Brainstorming on Behavior
• Brainstorming is a technique that, when used
  effectively, allows you to draw out more
  information than you might have otherwise. To
  brainstorm a particular topic, write down any
  words that come to mind during the time allotted.
  Try to continue writing throughout the time given
  and do not stop to analyze any of the words you
  have written down.

1. The word you are to brainstorm is behavior.
Behavior is the way an organism reacts to changes
in its internal condition or external
environment. On a sheet of paper, make a list of
as many behaviors as possible. You will have two
minutes. 2. After you have finished this
section, revisit your list. Write the letter I
next to any words that describe innate, or
unlearned, behaviors. Write the letter L next
to any words that describe learned behaviors.

Figure 345 Pavlovs Experiment
Section 34-1
After Conditioning When Pavlov rang a bell inthe
absence of food, the dogstill salivated. The dog
was conditioned to salivate in response to a
stimulus that it did not normally associate with
food.
Before Conditioning When a dog sees or smells
food, it produces saliva. Food is the stimulus
and the dogs response is salivation. Dogs do not
usually salivate in response to nonfood stimuli.
During Conditioning By ringing a bell every time
he fed the dog, Pavlov trained the dog to
associate the sight and smell of food with the
ringing bell.

• How Do You Behave?
• In an average day, you exhibit numerous
  behaviors. Some behaviors are learned and some
  are innate.

1. Think of a behavior that you can picture
yourself doing. What behavior did you choose? 2.
When do you think you first exhibited this
behavior? 3. What process was involved in the
development of this behavior? 4. Do you think
this behavior is innate or learned? Explain your
answer.
