4. Piaget’s Approach to Cognitive
Development
Learning Objective Questions
What are the fundamental
features of Piaget’s theory
of cognitive development?
How has Piaget’s theory
been supported and
challenged by later
research?
Clipart
5. Piaget’s Approach to Cognitive
Development
Infants do not acquire
knowledge from facts
communicated by
others, nor through
sensation and perception
Knowledge is the product
of direct motor behaviour

9. Piaget’s Approach to Cognitive
Development
Substage 1: Simple Reflexes
Spans the first month of
life
Inborn reflexes are at the
center of both the physical
and cognitive
development, which
determines their
interactions with the world
Babies gain information and
knowledge about the world
around them based on
reflex interactions
Reflexes also begin to

10. Piaget’s Approach to Cognitive
Development
Substage 2: First Habits and Primary Circular
Reactions
Occurs from 1 month to 4 Primary Circular
months of age Reactions: infant’s
Infants begin to coordinate
repetition of interesting or
separate actions into enjoyable activities, just
single, integrated activities for the enjoyment of doing
them
If an activity catches a
Babies are focusing on
baby’s interest, they will
repeat it to continue activities that involve their
experiencing that activity own bodies
11. Piaget’s Approach to Cognitive
Development
Substage 3: Secondary Circular Reactions
4 to 8 months Major difference is
Behaviour becomes more whether baby’s actions are
purposeful and infants focused on his/her own
begin to act of their body (primary) or actions

13. Piaget’s Approach to Cognitive
Development
Substage 5: Tertiary Circular
Reactions
12 to 18 months During this stage the main
Tertiary Circular focus is on the unexpected
Reactions: the deliberate and rather than just
variation of actions that repeating an enjoyable

consequences
Clipart
14. Piaget’s Approach to Cognitive
Development
Substage 6: Beginnings of Thought
18 months to 2 years old
Capacity for mental
representation or symbolic
thought
Mental Representation: an
internal image of a past
event or object
Children are able to
imagine where objects are
that they are unable to
see
Clipart
15. Piaget’s Approach to Cognitive
Development
Substage 6: Beginnings of Thought
Due to their ability to
create internal
pictures, their
understanding of causality
also become much more
sophisticated
The ability to pretend also
develops in this stage
Deferred Imitation: an act
in which a person who is no
longer present is imitated
by children who have Clipart
witnessed a similar act
16. Piaget’s Approach to Cognitive
Development
Appraising Piaget: Support
Piaget was masterful Broad outlines sketched
reporter of child behaviour out of the sequence of
and his description of cognitive development and
growth during infancy is the increasing cognitive
extremely accurate accomplishments that
Thousands of studies have occur in infancy are
supported Piaget’s view generally accepted to be
that children learn by accurate
acting on the objects in
their environment
Clipart
17. Piaget’s Approach to Cognitive
Development
Appraising Piaget: Challenges
Stage concept that is the
basis of Piaget’s theory
Notion that cognitive
development is grounded in
motor activities
Belief that infants are
incapable of developing
object permanence before
the age of 1
Work seems to describe
children from
Clipart developed, western
countries better than those
of non-western cultures
19. Information-Processing Approaches to
Cognitive Development
Learning Objective Questions
How do infants process
information?
What are the memory
capabilities of infants?
How is infant intelligence
measured?
Clipart
20. Information-Processing Approaches to
Cognitive Development
Information processing
approach:
Seeks to identify the way
in which individuals take
in, use and store
information
The infant’s ability to
organize and manipulate
information demonstrates
the level of cognitive
Clipart
development
21. Information-Processing Approaches to
Cognitive Development
Encoding, Storage and Retrieval
Encoding: process in which
information is recorded in
a from usable to the
memory
Storage: placement of
information into the brain
Retrieval: ability to locate
the information, bring it
into awareness and use it
Clipart
22. Information-Processing Approaches to
Cognitive Development
Encoding, Storage and Retrieval
Automatization: degree to
which an activity requires
attention
Automatic: little to no
attention (ex.
walking, eating)
Controlled: large amount
of attention required (ex.
studying)
Clipart
23. Memory and Infants
1. Do infants have a memory?
Why? Why not?
2. Do you remember anything
from when you were a
baby?
3. Do you think it is possible?
24. Information-Processing Approaches to
Cognitive Development
Memory Capabilities in Infancy
Infants do have memory
capabilities
Habituation: lessened
response to a repeated
stimulus
Rovee-Collier Experiment
As we grow our memory
increases, recall increases,
and we can remember
information longer http://www.tusculum.edu/faculty/home/tharlow/DE

25. Information-Processing Approaches to
Cognitive Development
Why Can’t We Remember Our Infancy?
Infantile Amnesia: lack of
memory for experiences
that occurred prior to 3
years of age
New information can keep
us from recalling old
memories
Forget memories as we get
older
Memories are susceptible
to mis-recollection
Clipart Memory Video
26. Information-Processing Approaches to
Cognitive Development
Cognitive Neuroscience of Memory
Two systems involved in
long-term memory:
Explicit Memory: conscious
and can be recalled
intentionally (Cerebellum
and brain stem)
Implicit Memory: not
conscious of it but affects
performance and behaviour

Intelligence
What is intelligence?
No specific definition of
intelligence
Difficult to measure
intelligence in infants
28. Information-Processing Approaches to
Cognitive Development
Arnold Gesell
Formulated earliest measure
of infant development
Developmental Quotient
(DQ): overall developmental
score that relates to
performance in 4 domains:
Motor Skills
Language Use
Adaptive Behaviour
Clipart
Personal-Social

Cognitive Development
Nancy Bayley
Bayley Scales of Infant Mental abilities:
Development: perception, memory,
Widely used measure for learning, problem solving,
infants and language
Evaluates infant Motor abilities: fine and
development from 2-42 gross motor skills
months Provides a DQ score
Average score for infants
is 100.
Clipart
31. Information-Process Approaches to
Individual Differences in Intelligence
Research shows that the
speed with which infants
process information may
correlate with later
intelligence (academic)
Test speed of processing
by using:
1. A habituation test:
faster the baby turns away
= speed of processing
2. Visual recognition test:
Clipart the memory and recognition
of a stimulus that has been
previously seen
32. Why Formal Education is Lost on
Infants
Many parents believe that by exposing their babies to
educational toys and media it will enhance their infant’s
cognitive growth
Educational videos such as Baby Einstein and Brainy Baby
promise to stimulate and enhance cognitive development
Do they work?
Evidence suggests that they don’t and in some cases
their use may backfire and hamper learning
Assume infants learn the same way as children do
through structured activities with specific learning
goals
Infants merely explore their surroundings in an
unplanned way
33. Infant Media Exposure and Toddler
Development Article
“Overall exposure and exposure to older child/adult–
oriented content were associated with lower levels of
cognitive and language development at age 14 months.
Findings from this longitudinal study provide strong
support for the American Academy of Pediatrics
recommendation of no media exposure before age 2
years (Berkule et al, 2010).”
Clipart
34. Infant Media Exposure and Toddler
Development Article
Three potential reasons for media-associated negative
effects on very young children's development:
1.Reductions in parent-child interactions, including
reduced spoken language, conversation, and
engagement with the child. Specifically reduced
shared reading and playing together with toys. These
are activities critical to young children's
development.
2.Interferes with children's play activities.
3.Characteristics of videos such as rapid scene changes
have been thought to have direct, negative effects
on the developing brain
(Berkule et al, 2010)
35. Why Formal Education Is Lost on
Infants
Baby Einstein Refunds
Refunds to millions of
parents who had bought
the videos because
parents said they were
ineffective in promoting
cognitive development
They have some benefits
however:

36. Baby Einstein Discussion
Do you think that purchasing
educational toys and media for
infants is worth a try, despite the
lack of scientific research?
Why do you think parents generally
do not seem to be concerned about
the lack of scientific evidence?
38. The Roots of Language
Learning Objective Questions
What processes do
children learn to use
language?
How do children influence
adults’ language?
Clipart
39. The Roots of Language
Baby’s First Words
The first and most
noticeable expression of
language
However, infants begin to
understand the language
used by others many
months earlier
This helps them make
sense of the world around
them
Clipart
40. The Roots of Language
The Fundamentals of Language: From Sounds
to Symbols
Language: the
systematic, meaningful
arrangement of
symbols, provides the basis
for communication
It is closely tied to the
way we think and
understand the world
It enables us to reflect on
people and objects and to Clipart
express our thoughts to
others
41. The Roots of Language
Formal Characteristics of Language
Each characteristic must be
mastered as linguistic
competence is developed
1. Phonology: refers to the
basic sounds of
language, called
phonemes, that can be
combined to produce words
and sentences
http://itp.nyu.edu/~kh1243/blizzog/h
Ex. “a” in “mat” represents a
tml5/1322
phoneme – the English
Language contains 40
42. The Roots of Language
Formal Characteristics of Language
2. Morphemes: the
smallest language unit that
has meaning. Some
morphemes are complete
words while others add
information necessary for
interpreting a word (“ish”)
3. Semantics: the rules
that govern the meaning of
words and sentences
Clipart
43. The Roots of Language
The Fundamentals of Language
When studying the
development of language
we need to distinguish
between:
Linguistic Comprehension:
the understanding of
speech
AND
Linguistic Production: the
use of language to
communicate
Clipart
44. The Roots of Language
The Fundamentals of Language
Clipart
45. The Roots of Language
Early Sounds and Communication
Sounds that infants make
play a very important role
in linguistic development:
Cooing
Crying
Gurgling
Murmuring
Clipart
47. The Roots of Language
Early Sounds and Communication
Pre-linguistic
Communication:
communication through
sounds, facial expressions,
gestures, imitation, and
other non-linguistic means
Mimics the back-and-forth
of communication and
teaches the child about
turn-taking
Clipart
48. The Roots of Language
Babbling: making speech
like but meaningless
sounds, starts at the age
of 2 or 3 months and
continues until around the
age of 1 year
To Twins Babbling Back and Forth
49. The Roots of Language
Early Sounds and Communication
Babbling is found
universally and is
accomplished in the same
way throughout all cultures
While babbling, infants
produce all of the sounds
found in every language
Clipart
50. The Roots of Language
Early Sounds and Communication
Deaf children who are
exposed to sign language
babble with their hands
instead of their voices
Their gestural babbling is
similar to the verbal
babbling of children who
can speak
Clipart
51. The Roots of Language
Early Sounds and Communication
Broca’s Area: areas of
the brain activated during
the production of hand
gestures are similar to the
areas activated during
speech production
Suggests that spoken
language may have evolved
from gestural language
(Feldman, 2012)
52. The Roots of Language
Early Sounds and Communication
As the child develops,
babbling moves from simple
to more complex sounds
By the age of 6 months,
babbling reflects the sounds
of the language that is
spoken by those around the
child
Other indications of pre-
linguistic speech: reaching
or crying for something that
results in receiving what is
Clipart wanted - communication
53. The Roots of Language
First Words
First words typically are
spoken at approximately
10-14 months
Can occur as early as 9
months
Linguists argue about what
constitutes an infant’s
first word
54. The Roots of Language
First Words
Once an infant starts to
produce words, vocabulary
increases at a very rapid
rate
By 15 months a child
has, on average, a 10
word vocabulary
One word stage ends
around 18 months Clipart
55. The Roots of Language
First Words
Early vocabularies typically
regard objects and things,
both animate and inanimate
Most often people or
objects who constantly
appear and disappear
(“Mama”)
Explosion of language:
Between 16-24 months
Vocabulary increases
Clipart
from 50 to 400 words
56. The Roots of Language
First Words
First words are usually
Holophrases: one-word
utterances that stand for a
whole phrase, whose
meaning depends on the
particular context in which
they are used
Ex. “ma” may be used to
mean “Where’s Mom?” or “I
want to be picked up by
Mom” Clipart
58. The Roots of Language
First Words
Culture has an effect on
first words:
North American English-
speaking infants – more
apt to use nouns
Chinese Mandarin – more
apt to use verbs
By 20 months there are
outstanding similarities
cross-culturally in words Clipart
spoken
60. The Roots of Language
First Sentences
The explosive increase in
vocabulary is accompanied
by another triumph:
Linking together
individual words into
sentences that express a
single thought
Two-word phrases occur
8-12 months after
infants say their first
word
Clipart
61. The Roots of Language
First Sentences
Most early sentences don’t
represent demands or
require a response
Often merely comments
and observations about
events
Two-word combinations
tend to be constructed in
same way as adult
sentences: subject
verb object Clipart
62. The Roots of Language
First Sentences
Telegraphic Speech:
speech in which words not
critical to the message are
left out
Instead of “Josh threw the
ball” infants may say:
“Josh ball”
“Josh threw”
64. The Roots of Language
First Sentences
Underextension: the
overly restrictive use of
words, common among
children just mastering
spoken language
Ex. Inability to generalize
the label of “blankie” to
blankets in general
Clipart
65. The Roots of Language
First Sentences
Overextension: the overly
broad use of
words, overgeneralizing
their meaning
Ex. Referring to
buses, trucks and tractors
as “cars”
Demonstrates that the
child is beginning to
develop general mental
Clipart
categories and concepts
66. The Roots of Language
First Sentences
Infants show differences
in the style of language
they use
Referential Style:
language is used primarily
to label objects (American)
Expressive Style: language
is used primarily to express
feelings and needs about
oneself and others
(Chinese)
Clipart
67. The Roots of Language
The Origins of Language Development
Learning Theory
Approach: the theory that
language acquisition follows
the basic laws of
reinforcement and
conditioning
Language is a learned skill
Children learn to speak by
being rewarded for making
sounds that estimate
speech Clipart
68. The Roots of Language
Nativist Approaches
Nativist Approach: the Universal Grammar: all
theory that a genetically the world’s languages share
determined, innate a similar underlying
mechanism directs language structure
development
Noam Chomsky: people
are born with an innate
capacity to use
language, which develops
when a child matures
Clipart
69. Nativist Approaches
Language-Acquisition
Device (LAD): a neural
system of the brain
hypothesized to permit
understanding of language
Language is unique to human
beings
Made possible by a genetic
predisposition to both
comprehend and produce
words and sentences
(Feldman, 2012, Pg. 162)
70. The Roots of Language
The Interactionist Approaches
Interactionist
Perspective: suggests that
language development is
produced through a
combination of genetically
determined dispositions
and environmental
circumstances that help
teach language
Innate and social
factors
Clipart
71. The Roots of Language
Speaking to Children
Infant-Directed Speech:
a type of speech directed
toward
infants, characterized by
short, simple sentences
Sometimes includes
humorous sounds that are
not even words
Directed speech changes
as the child becomes older
Grandma Talking To Baby
- longer and more complex
sentences
73. Is Infant-Directed Speech Similar in
All Cultures?

74. Is Infant-Directed Speech Similar in
All Cultures?
Gender Differences
From the time of birth, the
language parents use with
their children differs
depending on the child’s sex
By the age of 32 months,
girls hear twice as many
diminutives (ex. “kitty”
instead of “cat”) as boys
hear
Boys hear firmer, clearer
language while girls are
exposed to warmer phrases
(Feldman, 2012, Pg. 164)
75. Are You an Informed Consumer of
Development?
What Can You Do to Promote Infants’ Cognitive
Development?
