Developmental Psychology
Developmental psychology –
The study of how organisms change over
time as the result of biological and
environmental influences
Copyright © Allyn and Bacon 2006
How Do Psychologists
Explain Development?
Development is a process of
growth and change brought
about by an interaction of
heredity and the
environment
Copyright © Allyn and Bacon 2006
The Nature-Nurture
Interaction
Nature-nurture issue –
Long-standing discussion over relative
importance of nature (heredity) and
nurture (environment) in their influence
on behavior and mental processes

The Nature-Nurture Interaction
Twin studies and Adoption
Studies
• Developmental investigations
in which twins, especially
identical twins, are compared
in the search for genetic and
environmental effects
• Adoption studies –
Studies in which the adopted
child’s characteristics are
compared to those of the
biological family and the
adoptive family
Identical vs Fraternal
• Identical twins–
A pair who started life as a
single fertilized egg which
later split into two distinct
individuals
• Fraternal twins–
A pair who started life as two
separate fertilized eggs that
happened to share the same
womb

The Nature-Nurture
Interaction – The Jim Twins
Think/Pair/Share: How can twin studies help
us in psychology with respect to the
Nature/Nurture Debate?

Psychological Traits in Your Genes
While psychological traits are formed by
interaction of heredity and the
environment, many traits have a strong
genetic influence. However, we can never
discount the effects of the environment.

What Capabilities Does the
Child Possess?
Newborns have innate
abilities for finding
nourishment, interacting with
others, and avoiding harmful
situations; the developing
abilities of infants and
children rely on learning
Copyright © Allyn and Bacon 2006
Prenatal Development
Prenatal period –
The developmental period before birth
• Zygote – fertilized egg
• Embryo – 3 layers; heartbeat @ 3 weeks
• Fetus – 9 weeks
Placenta –
An organ that develops
between the embryo/fetus
and the mother
Teratogens –
Toxic substances that can damage the
developing organism
Copyright © Allyn and Bacon 2006
Neonatal Period
(from birth to one month)
Sensory abilities
Motor abilities
Postural reflex
Grasping reflex

A Recap! Infancy
(from one month to about 18 months)
• Rapid growth
• Many potential brain circuits are not fully
connected (no memory of events prior to
about age 3)
• Babies learn through classical conditioning
• Attachment
• Imprinting – Konrad Lorenz
Copyright © Allyn and Bacon 2006
Infancy
(from one month to about 18 months)
Humans apparently have an inborn need for
attachment - Mary Ainsworth
• Secure attachment
• Anxious-ambivalent attachment
• Avoidant attachment

Infancy
(from one month to about 18 months)
• Maturation –
The unfolding of
genetically programmed
processes of growth and
development over time
• Be familiar with the
maturation time line on
page 374 in your
textbook
Children “mature” at
their own rate.
If there are significant
delays (those doctors
visits are important!),
then a pediatric
specialist should be
consulted.

What Are the
Developmental Tasks of
Infancy and Childhood?
Infants and children face
especially important
developmental tasks in the
areas of cognition and social
relationships – tasks that lay a
foundation for further growth in
adolescence and adulthood
Copyright © Allyn and Bacon 2006
Cognitive Development – Jean Piaget
Cognitive development –
The process by which thinking changes
over time
Schemas –
Mental structures or
programs that guide a
developing child’s thoughts
Copyright © Allyn and Bacon 2006
Cognitive Development
Assimilation –
Interpreting one’s new
experiences in terms of one’s
existing schemas. Asking
how it fits into a current
schema.
Accommodation –
Adapting one’s current
understandings (schemas)
to incorporate new
information. Taking in the
new information and
AP Tip: Think of this like
rearranging the existing
generalization and
schema.
discrimination!

Piaget’s Stages of Cognitive
Development
Piaget believed that all
children “pass” through
these stages due to the
developing cognitive
(thinking/logic) ability of the
brain.
• Sensorimotor (Birth-2
years)
• Preoperational (2-7
years)
• Concrete Operational
(7-11 years)
• Formal Operational
(11 and up)
Copyright © Allyn and Bacon 2006
Sensorimotor – Birth – 2 years
Key Terms:
• Sensory and
Motor Skills
• Mental
Representations
• Object
Permanence
Overview:
• Child relies heavily on innate motor
responses to stimuli
• Children build mental representations
or mental images based on their schema
of objects in their world (goes along with
language development)
• By about 18 mo. babies realize that
objects continue to exist even when they
can’t see them; separation anxiety then
kicks in

Preoperational: 2-6/7 years
Key Terms:
Overview:
• Egocentrism
• Child believes the world revolves around
them and they can’t see things from
another person’s perspective
• Animistic
Thinking
• Inanimate objects have feelings
• Centration (lack of
conservation!)
• Irreversibility
• Center on only one bit of information at
a time (“I want the big glass of water!”)
• Cannot reverse operations (Adding is
easy, but subtracting is difficult)

Social and Emotional Development
Theory of Mind –
An awareness that other people’s behavior
may be influenced by beliefs, desires, and
emotions that differ from one’s own (story
of Stuffy the rabbit)
Temperament – (Jerome Kagan)
Inborn and stable rudiments of
personality, such as shyness and boldness
Copyright © Allyn and Bacon 2006
Social and Emotional Development
Lev Vygotsky: Zone of proximal development –
The difference between what a child can do with
help and what the child can do without any help
or guidance
Socialization –
The lifelong process of shaping an individual’s
behavior patterns, values, standards, skills,
attitudes and motives to conform to those
regarded as desirable in a particular society
Copyright © Allyn and Bacon 2006
Concrete Operational: 7-11
yrs.
Key Terms:
• Conservation
• Shift in Mental
Operations
Overview:
• An understanding that the physical
properties of an object or substance do
not change despite appearances (two
different size glasses will hold the same
amount of water; cutting a sandwich in
two is still one whole sandwich)
• Children start to “think things through”
and the magical thinking of earlier stage
starts to be questioned. (e.g. Belief in
Santa).

Formal Operational – Age 12 on
Key Terms:
• Abstract
Thought
Appears
Overview:
• Early adolescence is time when child
begins to grasp abstract ideas of moral
and ethics.
• This is typically when math becomes
more challenging (e.g., algebraic terms).

Social and Emotional Development
Other factor’s influencing a
child’s social development
may include:
• Effects of day
care
• School influences
• Leisure influences
Parenting Styles:
• Authoritarian (My way
or the highway!)
• Authoritative (Let’s
discuss the rules and
come to an agreement.)
• Permissive (Let’s be
besties!)
• Uninvolved (I have
kids?)

What Changes Mark the
Transition of Adolescence?
Adolescence offers new
developmental challenges
growing out of physical
changes, cognitive changes,
and socioemotional changes
Copyright © Allyn and Bacon 2006
The Transitions of Adolescence
Adolescence –
Developmental period beginning at
puberty and ending at adulthood
Rites of passage –
Social rituals that mark the transition
between developmental stages, especially
between childhood and adulthood
Copyright © Allyn and Bacon 2006
Cognitive Development in Adolescence
Hormones rise to high levels
The frontal lobes undergo a “remodel”
This leads to sensation seeking and risk
taking, and preoccupation with body
image and sex
Copyright © Allyn and Bacon 2006
Social and Sexual Identity in
Adolescence
Identity crisis
The increasing influence of peers
Common social problems in
adolescence
Delinquency
Sexual Identity comes into question

Kohlberg’s Stages of Moral
Reasoning
“Should Heinz have stolen the too expensive
medicine to save his wife’s life?”
I. Preconventional morality (like Piaget’s
egocentrism)
Stage 1: Pleasure/pain orientation – Avoid pain
or avoid getting caught
Stage 2: Cost/benefit orientation; reciprocity –
Achieve/receive rewards or mutual benefits
Copyright © Allyn and Bacon 2006
Kohlberg’s Stages of Moral
Reasoning
II. Conventional morality (like Piaget’s
Theory of Mind)
Stage 3: “Good child” orientation – Gain
Acceptance, avoid disapproval
Stage 4: Law-and-order orientation –
Follow rules, avoid penalties
Copyright © Allyn and Bacon 2006
Kohlberg’s Stages of Moral
Reasoning
III. Postconventional (principled) morality
Stage 5: Social contract orientation –
Promote the welfare of one’s society
Stage 6: Ethical principle orientation –
Achieve justice, be consistent with one’s
principles, avoid self-condemnation
Copyright © Allyn and Bacon 2006
Kohlberg’s Stages of Moral Reasoning
• Culture and morality
• Gender and morality – Carol Gilligan
• Studies have found no close connection between
people’s moral reasoning and their behavior.
Most moral reasoning comes after people have
intuitively decided how to act.
Copyright © Allyn and Bacon 2006
What Developmental
Challenges Do Adults Face?
Nature and nurture continue
to produce changes
throughout life, but in
adulthood these changes
include both growth and
decline
Copyright © Allyn and Bacon 2006
Elisabeth Kubler-Ross – Death and
Dying
Kubler-Ross identified 5
stages that terminally ill,
dying individuals, and
those experiencing grief
will go through
• Denial
• Anger
• Bargaining
• Depression
• Acceptance
