Infancy Cognitive
Development
“Baby Human – Face Recognition”
2 key ideas from birth:
•Born with more neurons
than an adult - “Pruning”
•Hyperattentive - Pay
attention to everything
(usually considered an
inability to focus)
Infancy and Childhood:
Cognitive Development
Schema
a concept or framework that organizes and
interprets information
Assimilation
interpreting one’s new experience in terms
of one’s existing schemas
Accommodation
adapting one’s current understandings
(schemas) to incorporate new information
Piaget’s Stages of
Cognitive Development
Typical Age
Range
Description
of Stage
Developmental
Phenomena
Birth to nearly 2 years
Sensorimotor
Experiencing the world through
senses and actions (looking,
touching, mouthing)
•Object permanence
•Stranger anxiety
About 2 to 6 years
Preoperational
Representing things
with words and images
but lacking logical reasoning
•Pretend play
•Egocentrism
•Language development
About 7 to 11 years
Concrete operational
•Conservation
Thinking logically about concrete
•Mathematical
events; grasping concrete analogies
transformations
and performing arithmetical operations
About 12 through
adulthood
Formal operational
Abstract reasoning
•Abstract logic
•Potential for
moral reasoning
Cognitive Development:
Sensorimotor Stage
Object Permanence
the awareness that things continue to exist even
when not perceived
No object permanence
A-not-B Error
Cognitive Development:
Sensorimotor Stage
Circular Reactions
Primary – baby accidentally does something
and repeats simply because it feels good
Saliva bubbles, waving arms
Secondary – similar to primary, but involve
objects in the environment
Example
Tertiary – infant devises new ways to act on
objects to produce interesting results.
Infancy and Childhood:
Cognitive Development
Baby Mathematics
Shown a numerically impossible outcome, infants
stare longer (Wynn, 1992)
4. Possible outcome:
Screen drops, revealing
one object.
1. Objects placed
in case.
2. Screen comes 3. Object is removed.
up.
4. Impossible outcome:
Screen drops, revealing
two objects.
Infancy and Childhood:
Cognitive Development
Scale Error in the Judy DeLoache Study
Found 18 – 30 month olds commonly make
Scale Errors
Infancy and Childhood:
Cognitive Development
Scale Error
Typical scale error ages
Cognitive Development
Self-Awareness – shopping cart study
Animism – belief that inanimate objects have
lifelike qualities and mental lives.
Preoperational
Seriation – Ability to arrange objects in
ascending or descending order based on
characteristic like length or weight
Concrete operations
Much later than people think
Infancy and Childhood:
Cognitive Development
Conservation
the principle that properties such as mass, volume,
and number remain the same despite changes in the
forms of objects
Preoperational vs. Concrete operational
Number, Mass, Length, Volume, Area, Weight
Infancy and Childhood:
Cognitive Development
Egocentrism
the inability of the preoperational child to take
another’s point of view
Example in Child’s answers:
Why does the sun shine? To keep me warm.
Why is there snow? For me to play in.
Why is the grass green? Its my favorite color.
Have a 4 year old close her eyes and ask her if
you can still see her. Her answer?
How many siblings? vs. how many kids do your
parents have?
Social Development
Health, happiness, and even survival
depends on forming meaningful, effective
relationships with family peers, and later,
on the job (Zimbardo, 2007)
Nature brings our 1st step in this direction
– a biological predisposition
to smile.
Social Development:
Temperament
Temperament – An individual’s
characteristic manner of behavior or
reaction
Assumed to have a strong genetic basis.
10-15% babies “born shy”, 10-15% “born
bold”
Nature / Nurture connection – which
temperaments encourage interaction?
Social Development
Attachment
an emotional tie with another person
shown in young children by their seeking
closeness to the caregiver and displaying
distress on separation
Develops in phases over 1st 24 months.
Once attachments are formed, fears and
anxieties also appear.
Social Development
Stranger Anxiety
fear of strangers that infants commonly
display
beginning by about 8 months of age
Separation Anxiety
Distress the infant shows when object of
attachment leaves
Peaks between 14 and 18 months
“The Strange Situation”
Mary Ainsworth – Attachment studies
Displays attachment
Secure Attachment (Ideal) – 60%
Children show some distress when parent leaves,
seek contact at the reunion, explore when parent
gone, play and greet when parent present.
Insecure Attachments lack 1 or more of these
traits
Behaviorists: What should the parent do in this
scenario (assuming its real)?

Origins of Attachment
Critical Period
an optimal period shortly after birth when an
organism’s exposure to certain stimuli or
experiences produces proper development
Imprinting – Konrad Lorenz
the process by which certain animals
form attachments during a critical
period very early in life
Origins of Attachment
Harlow’s Surrogate
Mother Experiments
Monkeys preferred
contact with the
comfortable cloth
mother, even while
feeding from the
nourishing wire
mother
Social Development
Monkeys raised
by artificial
mothers were
terror-stricken
when placed in
strange
situations
without their
surrogate
mothers.
Social Development
Basic Trust (Erik Erikson)
a sense that the world is predictable and
trustworthy
said to be formed during infancy by
appropriate experiences with responsive
caregivers
Self-Concept
a sense of one’s identity and personal
worth
Social Development: ChildRearing Practices
Authoritarian
parents impose rules and expect obedience
“Don’t interrupt.” “Why? Because I said so.”
Permissive
submit to children’s desires, make few
demands, use little punishment
Authoritative
both demanding and responsive
set rules, but explain reasons and encourage
open discussion
