INNATE AND LEARNED BEHAVIOR
E3.1 DISTINGUISH BETWEEN INNATE AND LEARNED
BEHAVIOR.
Innate Behavior
Instinctive – ___________ based
Not modified by the individual
_________ through population
Unaffected by environment
___________________ are
product of natural selection
e.g. suckling in newborns
__________ of blackcaps
hunting instinct
Learned Behavior
Based on ____________
Modified by trial and error
_________ within population
Affected by environment
__________________ may be
product of natural selection
e.g. __________
response to predators
E3.2 DESIGN EXPERIMENTS TO INVESTIGATE INNATE
BEHAVIOR IN INVERTEBRATES, INCLUDING EITHER A TAXIS
OR A KINESIS.
TAXI
S
Plural, _________
An innate ____________ movement __________
(positive) or ________________ (negative) some
stimulus.
E3.2 DESIGN EXPERIMENTS TO INVESTIGATE INNATE
BEHAVIOR IN INVERTEBRATES, INCLUDING EITHER A TAXIS
OR A KINESIS.
TAXI
S
___________ are model species for innate behavior studies:
ex: positive _________ = move toward warmer areas of water
positive _________ = move toward acids released by
bacteria (their food)
negative _________ = avoid high concentrations of
harmful chemicals
E3.2 DESIGN EXPERIMENTS TO INVESTIGATE INNATE
BEHAVIOR IN INVERTEBRATES, INCLUDING EITHER A TAXIS
OR A KINESIS.
KINESIS
Plural, ________
An innate ______________ movement in response
to a stimulus.
May be merely starting or stopping, changing _____,
or __________ more or less frequently.
E3.2 DESIGN EXPERIMENTS TO INVESTIGATE INNATE
BEHAVIOR IN INVERTEBRATES, INCLUDING EITHER A TAXIS
OR A KINESIS.
KINESIS
_______________ in pillbugs (Porcello scaber)
______________________ altered as response to stimulus
___________ of testing chamber is adjusted and behavior
is measured
Floor of chamber has ______
Movement is video recorded for __________________
E3.2 DESIGN EXPERIMENTS TO INVESTIGATE INNATE
BEHAVIOR IN INVERTEBRATES, INCLUDING EITHER A TAXIS
OR A KINESIS.
KINESIS
Orthokinesis in pillbugs (Porcello scaber)
Video played back, with ______________________
counted as movement in the time period
______________________ calculated as number of
squares crossed per second (mean of six runs)
E3.2 DESIGN EXPERIMENTS TO INVESTIGATE INNATE
BEHAVIOR IN INVERTEBRATES, INCLUDING EITHER A TAXIS
OR A KINESIS.
KINESIS
_______________ in pillbugs (Porcello scaber)
________________ altered as response to stimulus
Same as orthokinesis, but with ______________ per
unit time as the basis for calculation
E3.3 ANALYZE DATA FROM INVERTEBRATE BEHAVIOR
EXPERIMENTS IN TERMS OF THE EFFECT ON CHANCES
OF SURVIVAL AND REPRODUCTION.
In this investigation, pillbugs (P. scaber) were given a
choice chamber test.
One chamber contained _______ filter paper, the other
_____.
E3.3 ANALYZE DATA FROM INVERTEBRATE BEHAVIOR
EXPERIMENTS IN TERMS OF THE EFFECT ON CHANCES
OF SURVIVAL AND REPRODUCTION.
In the sample data, the overall movement of pillbugs is to
the __________ chamber. When the experiment is
repeated, results are consistent.
Those innate behaviors that are ________ (such as finding
moisture) give an individual a ________ and ___________
advantage.
As innate behaviors
are genetic, they are
______________, and
proliferate in the
population.
E3.4 DISCUSS HOW THE PROCESS OF LEARNING CAN
IMPROVE THE CHANCE OF SURVIVAL.
Innate behaviors are inherited from parents as _____. They
develop by __________________ and thus are suited to better
adapted species to its environment. Therefore, they
increase an animal’s chances for survival.
Learned behaviors develop as a result of __________. They
enable animals to _________ their behaviors in response to
changing environmental conditions. This increases the
chance of survival by learning new behavioral patterns.
While learned behavior itself is not passed on through
genetics, the ____________________ may be.

E3.5 OUTLINE PAVLOV’S EXPERIMENTS INTO
CONDITIONING OF DOGS.
E3.5 OUTLINE PAVLOV’S EXPERIMENTS INTO
CONDITIONING OF DOGS.
___________________ is a method of associative learning.
Ivan Pavlov trained dogs to _____________________ to a
stimulus, based on the dogs’ expected outcomes of the
behavior.
Classical conditioning results in an ___________________
to a stimulus (e.g. a bell ring)
E3.5 OUTLINE PAVLOV’S EXPERIMENTS INTO
CONDITIONING OF DOGS.
E3.5 OUTLINE PAVLOV’S EXPERIMENTS INTO
CONDITIONING OF DOGS.
______________________
- automatic response to a stimulus (i.e. food causes salivation)
_______________________
- does not elicit response (i.e. bell does not cause salivation)
_______________________
- neutral and unconditioned
stimuli applied together
(i.e. dog associates bell with
food, and salivates)
_______________________
_______________________
- Ringing the bell results in
salivation, even without food present.
E3.5 OUTLINE PAVLOV’S EXPERIMENTS INTO
CONDITIONING OF DOGS.
______________________ is another conditioning method
proposed by BF Skinner
_______________________: Reward desired behavior
_______________________: Punish incorrect behavior
Example:
rats and pigeons were
trained to push levers
and perform actions to
receive food rewards.
An electrical shock
punished incorrect
actions.
E3.6 OUTLINE THE ROLE OF INHERITANCE AND
LEARNING IN THE DEVELOPMENT OF BIRDSONG IN
YOUNG BIRDS.
Birdsong is a strong indicator of _____________________.
Birdsong development is due to both _________ and
___________ behavior.
This leads to ____________________ – usually the female
selects mates based on their perceived levels of
reproductive fitness.
The basis of much birdsong is ___________, though needs
to be refined with learning.
Example: _______________ ability to mimic any sound in
its environment

E3.6 OUTLINE THE ROLE OF INHERITANCE AND
LEARNING IN THE DEVELOPMENT OF BIRDSONG IN
YOUNG BIRDS.
Bird usually hatch with a ____________
_________ that prevents them from
learning from the wrong species.
_____________ takes place in the
sensitive period early in the
development (__________ learning).
By listening and practicing the calls
of the adult birds, the chick modifies
its song to “______”.
One reason why captive birds are
not reproductively successful in the
wild is that they ___________________
with the correct mature song.
