Topic Infancy Childhood
2Infancy Childhood Physical Development
3Physical Brain Development
- During prenatal
development, the brain
produces 250,000 neurons/minute - Peak 28 billion neurons at
7 months (prenatal) - By birth, this number has been pruned to 23
billion - By the end of the first year, the brain is about
35 larger than it was at birth

5Physical Brain Development
- Brain development unfolds according to genetic
instructions, causing various bodily and mental
functions to occur in sequence - Maturation
- The orderly sequence of biological growth
processes - Relatively uninfluenced by experience
- EXAMPLE
- Memory not solidified until after 3rd birthday
known as infantile amnesia
6Physical Motor Development
- Cephalocaudal Development
- The head develops before the arms trunk
- The arms trunk develop before the legs
- Proximodistal Development
- The head, trunk and arms develop before the hands
fingers - Applies to both prenatal development AND
development during the first two years
7Physical Motor Development
- Motor Milestones
- Raising head chest (2-4 months)
- Rolling over (2-5 months)
- Sitting up with support (4-6 months)
- Sitting up without support (6-7 months)
- Crawling (7-8 months)
- Walking (8-18 months)
8Infancy Childhood Cognitive Development
9Cognitive Development
- Cognition
- All mental activities associated with
thinking, knowing, remembering and
communicating - Jean Piaget (1896-1980)
- Piaget DID NOT believe that a childs mind was a
mini-adult mind - Believed that cognitive development is shaped by
errors a struggle to make sense of our
experiences as children
10Cognitive Development
- Schemas
- A concept or framework that organizes
interprets information - Mental molds into which we pour our experiences
so that the maturing brain can continually build
upon concepts - Example
- If Bob points to a picture of an apple and tells
his child, thats an apple, the child forms a
schema for apple that looks something like the
picture
11Cognitive Development
- Assimilation
- Interpreting a new experience in terms of an
existing schema - Example
- Bobs child might see an orange say apple
because both objects are round - Accommodation
- The process of adjusting/modifying a schema
- Example
- When Bob corrects his child, the child might
alter the schema for apple to include round and
red

13Cognitive Development
14Piaget (1) Sensorimotor Stage
- Birth to 2 years
- Description of Stage
- The use of senses motor abilities to learn
about the world/ interact with objects in the
environment - Developmental Phenomena
- Object Permanence (unfolds gradually)
- The awareness that objects continue to exist when
not perceived - Critical step in developing language abstract
thought - Stranger Anxiety
- Separation Anxiety
15Piaget (1) Sensorimotor Stage
16Piaget (1) Sensorimotor Stage
- Criticisms of Stage
- Piaget believed that children in the sensorimotor
stage are incapable of thinking no abstract
concepts or ideas - Recent research suggests that children in the
sensorimotor stage can both think and count - Babies can
- Understand basic laws of physics
- Count (Karen Wynn)
17Piaget (1) Sensorimotor Stage
18Piaget (2) Preoperational Stage
- 2 to 7 years
- Description of Stage
- Children learn to use language as a means of
exploring the world however, they are not yet
capable of logical thought - Too young to perform mental operations lack
conservation - Developmental Phenomena
- Pretend Play
- Animism
- Egocentrism
- Centration
- Irreversibility
19Piaget (2) Preoperational Stage
20Piaget (2) Preoperational Stage
- Egocentrism
- Example
- John, do you have a brother?
- Yes.
- Whats his name?
- Jim.
- Does Jim have a brother?
- No.
21Piaget (2) Preoperational Stage
- Theory of Mind
- 4 to 5 years
- Peoples ideas about their own and others mental
states about their feelings, perceptions, and
thoughts, and the behaviors these might predict - Seek to understand
- Why their playmate is angry
- Why their sibling will share
- Why their parent would buy a toy
22Theory of Mind Test
A child without theory of mind, would assume that
Sally
A child with theory of mind, would assume that
Sally
23Piaget (2) Preoperational Stage
- Criticisms of Stage
- Judy DeLoache (1987) found that children as young
as 3 are able to use mental operations think
symbolically - When shown a model of a dogs hiding place, a 2
½-year-old could not locate the stuffed dog in an
actual room, but a three year old could
24Piaget (3) Concrete Operational Stage
- 7 to 11 years
- Description of Stage
- Children become capable of logical thought
processes physical, concrete, touchable reality
lack abstract thinking - Developmental Phenomena
- Conservation
- Reversible thinking
- Mathematical transformation
- Developmental Limitations
- Abstract thinking
- Freedom, peace, love, etc.
25Piaget (4) Formal Operational Stage
- 12 years to adulthood
- Description of Stage
- The adolescent becomes capable of abstract
thinking - Developmental Phenomena
- Abstract logic
- Hypothetical thinking
- If women were in charge of countries, would
there be fewer wars? - Potential for mature moral reasoning
26Reflecting on Piagets Theory
- Globally influential however, todays
researchers believe the following - Development is a continuous process
- Children express their mental abilities
operations at an earlier age - Formal logic is a smaller part of cognition
27Vygotsky Sociocultural Theory
- Lev Vygotsky (1896-1934)
- Stressed the importance of social interactions
with other people, especially highly skilled
children or adults, in the childs cognitive
development
28Vygotsky Sociocultural Theory
- Scaffolding
- Process in which a more skilled learner gives
help to a less skilled learner, reducing the
amount of help as the less skilled learner
becomes more capable - Zone of Proximal Development (ZPD)
- The difference between what a child can do alone
and what the child can do with the help of a
teacher
29Vygotsky Sociocultural Theory
- Example
- If Jenny can do math problems at a 4th grade
level on her own, but can work up to a 6th grade
level with the help of a teacher, her ZPD is two
years - If Suzy can do math problems at a 4th grade level
on her own, but can work up to a 5th grade level
with the help of a teacher, her ZPD is one year
not as great as Jennys

31Language Development
- Cooing
- 2 months of age begin to make vowel-like sounds
- Babbling
- 6 months of age add consonant sounds to vowels
- Holographic Speech
- 1 year Milk! or Ball!
- Telegraphic Speech
- 1 ½ to 2 years short, simple sentences Baby
eat or Mommy go or Where ball? or Doggie go
bye-bye - Whole Sentences
- Preschool years
32Infancy Childhood Psychosocial Development
33Psychosocial Temperament
- Temperament
- The behavioral and emotional characteristics that
are fairly well-established at birth - Alexander Thomas Stella Chess (1986)
- Easy Babies
- Regular, good-natured, easy to care for,
adaptable - Difficult Babies
- Irregular, moody loud, react negatively to new
situations - Slow-to-Warm-Up Babies
- Quieter, slow to respond to new situations
34Psychosocial Temperament
- Psychologist, Jerome Kagan has added a fourth
temperament - Shy Child
- Timid and inhibited fearful of anything new or
strange - Longitudinal research (Kagan, 1998) strongly
suggests that these temperament styles last well
into adulthood, although there is the potential
for environmental influence - Goodness of fit
35Psychosocial Attachment
- Attachment
- The emotional bond
between an infant and
the
primary caregiver - Demonstrated by a childs
closeness-seeking and
distress upon separation - Develops within the first
six months of life
36Psychosocial Attachment
- Attachment through
contact - Humans form a bond with
those who care for them in
infancy based upon interaction
with caregiver - Harry Harlow
- Role of physical contact, or
contact comfort in
attachment

38Psychosocial Attachment
- Attachment throughout
familiarity - Occurs in many species of animals during a
critical period - Konrad Lorenz
- Imprinting
- The tendency to follow the first moving object
seen as the basis for attachment

40Psychosocial Attachment
- Mary Ainsworth
- The Stranger Situation
- Identified 4 distinct styles of
attachment - Secure
- Avoidant
- Ambivalent
- Disorganized-Disoriented
41Ainsworth (1) Secure Attachment
- Characteristics
- Very willing to explore
- Frequently touched base
- Wary of strangers, but calm as long as the
mother was nearby - When the mother left, the infant was noticeably
upset however, he or she was easily soothed upon
her return - Generally corresponds to secure attachment in
adulthood
42Ainsworth (2) Avoidant Attachment
- Characteristics
- Only somewhat willing to explore
- Did not touch base
- Did not look at strangers
- Reacted very little to mothers
absence or to her return - Generally corresponds to dismissive attachment
in adulthood
43Ainsworth (3) Ambivalent Attachment
- Characteristics
- Unwilling to explore clingy
- Very upset by strangers regardless of mothers
presence - Very upset by mothers departure not easily
soothed - Mixed reaction to mothers return
- Generally corresponds to preoccupied
attachment in adulthood
44Ainsworth (4) Disorganized Attachment
- Characteristics
- Subsequent studies by Mary
Main Erik Hesse (1990) - Sometimes referred to as
Disorganized-Disoriented
Attachment - Generally fearful with dazed
and depressed expression - Unable to decide how they
should react to their mothers return
little to no eye contact
45Psychosocial Attachment
- Deprivation of Attachment
- Impact of denying monkeys physical
comfort
from their mother? - Cases of Genie and Victor
- Daycare?

48Psychosocial Attachment
- Erik Erikson
- Concept of Basic Trust
- Securely attached children tend to believe that
the world is predictable and trustworthy - Erikson attributed attachment basic trust to
parenting - Identified eight stages of psychosocial
development first four occur during childhood
each contains a developmental crisis - Trust versus Mistrust (Birth1 year)
- Autonomy versus Shame Doubt (13 years old)
- Initiative versus Guilt (35 years old)
- Industry versus Inferiority (512 years old)
49Psychosocial Parenting Styles
- Diana Baumrinds THREE PRIMARY Styles
- Authoritarian
- Demanding not responsive
- Impose rules and expect obedience
- Permissive
- Not demanding, but responsive
- Use little punishment
- Authoritative
- Demanding and responsive
- Exert control by establishing/enforcing rules,
but they also explain the reasons for the rules
50Psychosocial Self-Concept
- Self-Concept
- Understanding of who we are
- Just as infants can achieve attachment, children
must achieve a positive self concept develops
gradually in the first year - Mirror Test
- By 18 months, children know THEY are the image in
the mirror - Children with a positive self-concept are more
confident, assertive, optimistic and
socialablehow is this achieved?
51Relationships with Other Children
- Solitary Play
- Children first play by themselves
- Parallel Play
- As they get older, children play side-by-side
with other children, but do not interact - Cooperative Play
- By about 3 1/2, children begin playing with
others - Peer Group
- A network of same-aged friends and acquaintances
who give one another emotional social support
