gradually learns to discover the location of
hidden objects at about eighteen months, when the
concept of object permanence is fully understood.

Question ????
Question - Why does a 1 year old child like
playing peek-a-boo, but a 7 year old child thinks
the game is silly?
Answer - Object Permanence
18
OBJECT PERMANENCE and CONSERVATION
19
Object Permanence and Conservation
1.The following demonstrations will be aided by
the presence of two children, one about eight
months old and one about seven years old.
However, they can easily be done without any
subjects. 2.Hold up the handkerchief and the
keys. Place the keys under the handkerchief and
say If I asked you where the keys are, you would
know, of course. But consider the stages an
infant must go through to find the hidden
object.
20
Object Permanence and Conservation
STAGE 1 (FROM BIRTH TO ABOUT A MONTH) An
infants eyes do not (and may be unable to)
follow the object, even as you move it in front
of the infants face.
21
Object Permanence and Conservation
STAGE 2 (ABOUT 1 TO 4 MONTHS) An infants eyes
can follow a moving object, but to the infant the
object does not exist if it is not visible if,
for example, it is under the handkerchief. Out of
sight is out of mind.
22
Object Permanence and Conservation
STAGE 3 (4 MONTHS TO ALMOST A YEAR) The infant
will search for a missing object in the place
where the object usually appears. For example, if
you put the keys in the palm of your hand, close
your hand, and then open your hand, and then open
it and close it again, the infant will look for
the keys in your hand. But if you put the keys
under the handkerchief, the infant will still
look in your hand.
23
Object Permanence and Conservation
STAGE 4 (ABOUT A YEAR) At this stage the infant
will learn the concept of object permanence and
search for the keys under the handkerchief.
Until the infant learns this concept, nothing
exists outside the infants field of vision.

KOHLBERG is holding a CONVENTION on MORALS
27
Question ????
In Europe, a woman was near death from cancer.
One drug might save her, a form of radium that a
druggist in the same town had recently
discovered. The druggist was charging 2,000, ten
times what the drug cost him to make. The sick
womans husband, Heinz, went to everyone he knew
to barrow the money, but could only get together
about half of what it cost. He told the druggist
that his wife was dying and asked him to sell it
cheaper or let him pay later. But the druggist
said, no The husband got desperate and broke
into the mans store to steal the drug for his
wife.(Kohlberg 1969) 1.Should the husband have
done that? 2.Why?

Kohlbergs Moral Development stages
29
THE GOLDEN RULE
Do unto others as you would have others do unto
you!
Is this an example of a moral rule of conduct
that is universal?
BUDDHISM Hurt not others with that which pains
yourself.
Hinduism This is the sum of duty do not to
others which if done to thee, would cause thee
pain.

Examples of Kohlbergs ideas in U.S.
Congressional Debates
The following are actual quotations from U.S.
debates on a resolution supporting the
administrations policy on Iraqs invasion of
Kuwait.
Arguments Against U.S. Involvement
We shouldnt consider warbecause it would hurt
our economy. (1)
because well have more money for domestic
issues (2)
because we dont want to appear too
militaristic. (3)
because war is killing and killing is against
the law. (4)
even though the situation is bad, war is
damaging to people and property and society
agrees that is bad (5)
although atrocities have been committed, it
would be an even greater atrocity to wage war
(6)

Arguments For U.S. Involvement
We should consider oil because our oil is
threatened(1)
because we can gain security of the oil supply
(2)
because we dont want the world to see us as
weak (3)
because the U.N. has laid down written
resolutions which should be upheld (4)
the situation is extreme enough that societys
rights are threatened and need to be define(5)
Evil is on the march, and it would be morally
wrong to allow it to continue(6)
