PIAGET’S A-NOT-B
THEORY…
True or False?
Amber Reyes, Lauren Villagran, Melissa Avalos, Nanci Gonzalez & Christopher Rincon
BACKGROUND
i. Young infants from the age range of 8-12 months and 12-18
months. Conducting the A-not-B experiment.
ii. Piaget’s Theory
iii. In our own study, we decided to challenge Piaget’s Theory. We
took an object the children enjoyed the most and tested whether
or not it would motivate them to find the object and pass the test.
METHOD
i. Our group recreated Jean Piaget’s A Not B error experiment.
ii. We used Jayleen, Charlotte, and Penelope. Jayleen is our eleven-month old
subject from Lauren's family daycare. Charlotte is our ten-month old subject
and is Lauren’s cousin. Penelope is our seventeen-month old subject and is
Lauren’s niece.
iii. Our group used three female infants, two of the three infants ranging from
the eight to twelve-month range, and one infant from the twelve to eighteen-
month range, to test and see if they would support Piaget’s theory.
TEST SUBJECTS
#1 Penelope Marte
12-18 month old infant
#2 Charlotte Jimenez
8-12 month old infant
TEST SUBJECTS
#3 Jayleen Gomez
8-12 month old infant
QUESTION?
If you were to hide an object a child desires, would they have a
greater chance of passing the A-not-B experiment, rather than an
object they do not desire at all?
EVIDENCE #1
PART 2
RESULTS
Results have shown that subject Penelope, an 12-18 month old
infant, passed the A-not-B experiment. Just as Piaget predicted in his
own studies.

EVIDENCE #3
PART 2
RESULTS
Both Charlotte Jimenez and Jayleen Gomez, infants of 8-12
months, successfully passed the A-not-B experiment. Contradicting
Piaget’s Theory of infants of the age range of 8-12 months would
not pass the experiment.
DISCUSSION
Unexpectedly, the experiment showed a different result from what
Piaget had instated in his theory. Infants of 8-12 months were said to not
be able to pass this task. However, the infants from12-18 months still
proved Piaget’s theory that children of this age can pass the test.
Our results proved that Piaget’s theory had not been completely true.
Even though, Piaget had been right that infants of 12-18 months would
pass, he had been wrong about infants of 8-12 months not being able to
pass due to them not having object permanence.
DISCUSSION
We can conclude from our results that there is a new perspective in
Piaget’s Theory of A not B. Our research shows that if a child is
motivated to find the toy, he/she will be more inclined to find it.
Would other 8-12 month olds keep passing the test if they have
the motivation to do so like the others?
Did Piaget take into account the motivation of the test subjects to
find the required object?

series of four critical stages of cognitive development. Each stage is
marked by shifts in how kids understand the world.

-Piaget’s theory 8-12 month old infants are more aware to search for
the toy under the first hiding place than the new hiding place
-Piaget’s theory proved that the toy the infants love the most was
unsuccessful because they had a hard time looking for it than with the
unfamiliar toy.
