 Development is lifelong.
 The process of human development are interwoven.
 Development is multi-directional.
 Development is highly plastic.
Life-span Perspective on Development?

 Development is influenced by historical conditions.
 Development is the concern of a number of disciplines.
 An individual responds and acts on contexts, which include
what was inherited, the physical environment, social,
historical and cultural context.
Life-span Perspective on Development?

 Every individual is different from each other but at the same
time more like each other. This is because of interaction of
heredity and environment.
 Principle of heredity – mechanism for transmission of
characteristics by every species from one generation to
another.
Factors influencing Development

 The observable characteristics of an individual are result of
interaction between the person’s inherited traits and
environment.
 Genes set the limit and within that limit the environment
influences development.
 .
Factors influencing Development

 Development does not take place in vacuum, It is always
embedded in a particular socio-cultural context.
 Urie Bronfenbrenner believed that a person's development was
affected by everything in their surrounding environment.
 He divided the person's environment into five different levels:
the microsystems, the mesosystem, the exosystem, the
macrosystem, and the chronosystem
Context of Development

 Microsystem - The Bronfenbrenner theory suggests that the
microsystem is the smallest and most immediate environment
in which children live.
 The microsystem comprises the daily home, school or
daycare, peer group and community environment of the
children.

 Mesosystem - The mesosystem encompasses the interaction
of the different microsystems which children find themselves
in.
 System of microsystems and as such, involves linkages
between home and school, between peer group and family,
and between family and community.

 The Exosystem pertains to the linkages that may exist
between two or more settings, one of which may not contain
the developing children but affect them indirectly nonetheless.
 Based on the findings of Bronfenbrenner, people and places
that children may not directly interact with may still have an
impact on their lives. Such places and people may include the
parents’ workplaces, extended family members, and the
neighborhood the children live in.

 The Macrosystem is the largest and most distant collection of
people and places to the children that still have significant
influences on them.
 This ecological system is composed of the children’s cultural
patterns and values, specifically their dominant beliefs and
ideas, as well as political and economic systems.

 The Bronfenbrenner theory suggests that the chronosystem
adds the useful dimension of time, which demonstrates the
influence of both change and constancy in the children’s
environments.
 The chronosystem may include a change in family structure,
address, parents’ employment status, as well as immense
society changes such as economic cycles and wars.

 Durganand Sinha (1977) has presented an ecological model for
understanding the development of children in Indian context.
Ecology of the child could be viewed in terms of two concentric
layers. The “upper and the more visible layers” consist of home,
school, peer groups, and so on.
The most important ecological factors influencing development
of the child in the visible upper layer constitute the:
 (i) home, its conditions in terms of overcrowding, space
available to each member, toys, technological devices used, etc.,
 (ii) nature and quality of schooling, facilities to which the child is
exposed, and
 (iii) nature of interactions and activities undertaken with peer
groups from childhood onward.

 Developmental stages are defined by milestones.
 A milestone is a sort of marker that tells you where you are
while traveling. The term is drawn from literal stone markers
that were used to mark the passage of each mile on early
roads.
Overview of Development Stages

 The period from conception to birth.
 It last about for 40 weeks.
 Prenatal development is also affected by maternal
characteristics like mother’s age, nutrition and emotional state.
 Teratogens are environmental stages that causes deviation in
normal development that could lead to serious abnormalities
or death.
Prenatal Stages

 Teratogen: Any agent that can disturb the development of an
embryo or fetus. Teratogens may cause a birth defect in the
child. Or a teratogen may halt the pregnancy outright. The
classes of teratogens include radiation, maternal infections,
chemicals, and drugs.
 Environmental Pollutants and toxic wastes like carbon
monoxide, mercury and lead are also sources of danger to the
unborn child.
Prenatal Stages

Infancy (Birth to 1 year old)
Newborn usually refers to a baby from birth to about 2
months of age. Infants can be considered children anywhere
from birth to 1 year old

 Just before birth the newborns have most but not all brain
cells. The neural connections among these cells develop at a
rapid rate.
 Most of the neurons in brain gets created before the child is
born. But some areas of the brain make new neurons after
birth in a process called Postnatal Neurogenesis. A few areas,
including the cerebellum and the prefrontal cortex, continue
adding new neurons in infancy.
 The activities needed to sustain life functions are present in
newborn – it breathes, sucks, swallows and discharges the
bodily waste.
Infancy

 The newborn’s movements are governed by reflexes – which
are automatic, built in responses to stimuli.
 Before the newborns have had the opportunity to learn,
reflexes act as adaptive mechanisms.
Motor Development

 As the infant grows, the muscles and nervous system mature
which lead to the development of finer skills.
 The sequence of physical development is universal with minor
exception.
Motor Development

 Babies are born with all 5 senses—sight, hearing, smell, taste,
and touch. Some of the senses are not fully developed.
 Babies are born with the ability to focus only at close range.
This is about 8 to 10 inches, or the distance between a
mother's face to the baby in her arms.
 Hearing is fully developed in newborns.
 Studies have found that newborns have a strong sense of
smell. Newborns prefer the smell of their own mother,
especially her breast milk.
Sensory Abilities

 Babies prefer sweet tastes over sour or bitter tastes. Babies
also show a strong preference for human milk and
breastfeeding.
 Babies are comforted by touch. Placing a hand on your baby's
belly or cuddling close can help him or her feel more secure.
Sensory Abilities

 Each stage in cognitive development is characterized by a
distinct way of thinking and is age related.
 It is important to note that it is different way of thinking
which makes one stage more advanced than the other and not
the amount of information.
 The child during infancy experiences the world through senses
and interactions with objects.
Cognitive Development

 In Piaget's theory of cognitive development, infants develop
this understanding by the end of the "sensorimotor stage",
which lasts from birth to about two years of age.
 Object permanence is the understanding
that objects continue to exist even when they cannot be seen,
heard, touched, smelled or sensed in any way.

 Emotional well-being during the early years has a powerful
impact on social relationships.
 Children who are emotionally healthy are better able to
establish and maintain positive relationships with adults as
well as with peers.
 Their first relationships help shape who they are, who they
become, and their understanding of the world.
Socio-Emotional Development

 A six months old infant shows following characteristics-
 Knows familiar faces and begins to know if someone is a stranger
 Likes to play with others, especially parents
 Responds to other people’s emotions and often seems happy
 Likes to look at self in mirror
 The close emotional bond of affection that develop between
infants and their parents (caregivers) is called attachment.
 Harlow and Harlow conducted an experiment on baby
monkeys to see the level of attachment.

 This experiment clearly demonstrates that providing
nourishment or feeding was not crucial for attachment and
contact – comfort is important.

 Eric Erikson Theory –
Trust vs. mistrust is the first stage in Erik Erikson's theory of
psychosocial development. This stage begins at birth and lasts
through one year of age. Infants learn to trust that their
caregivers will meet their basic needs. If these needs are not
consistently met, mistrust, suspicion, and anxiety may
develop.

 Childhood is the age span ranging from birth to puberty.
 The child’s growth slows down during early childhood as
compared to infancy.
Childhood

 Physical development refers to the advancements and
refinements of motor skills, or, in other
words, children's abilities to use and control their bodies.
 The child develops physically, gains height, weight, learns to
walk, run, jump and play.
Physical Development

 Cephalocaudally Development –
 During Cephalocaudal development, the infant will learn to
control over their neck muscles first, which allows them to
hold their head upright and eventually look around.
Afterwards, they gain control over their shoulder muscles
allowing them to roll over.
 Lastly, control over the muscles in their torso allows them to
sit. The size of the head of an infant in relation to the rest of
the body during this development is always larger than the rest
of the body.

 Proximodistal Development –
 During Cephalocaudal development, the infant will learn to
control over their neck muscles first, which allows them to
hold their head upright and eventually look around.
Afterwards, they gain control over their shoulder muscles
allowing them to roll over.
 Lastly, control over the muscles in their torso allows them to
sit. The size of the head of an infant in relation to the rest of
the body during this development is always larger than the rest
of the body.

 Gross Motor Skills involves-
Use of arms and legs, moving around with confidence and
more purposefully in the environment.
 Fine Motor Skills involves –
Finger dexterity and eye-hand coordination.
Motor Development

 In Piaget's theory of cognitive development,
infants develop object permanence understanding by the end
of the "sensorimotor stage", which lasts from birth to about
two years of age.
 Object permanence is the understanding
that objects continue to exist even when they cannot be seen,
heard, touched, smelled or sensed in any way.

 The Preoperational stage is the second stage in
Piaget's theory of cognitive development.
 This stage begins around age two and lasts until
approximately age seven.
 During this period, children are thinking at a symbolic level
but are not yet using cognitive operations

 Egocentrism refers to the child's inability to see a situation
from another person's point of view.
 According to Piaget, the egocentric child assumes that other
people see, hear, and feel exactly the same as the child does.

 Animism refers to attributing life-like qualities to objects.
 The cup is alive, the chair that falls down and hits the child’s
ankle is mean, and the toys need to stay home because
they are tired.
 Centration is the tendency to focus on one salient aspect of a
situation and neglect other, possibly relevant aspects.

 The Concrete Operational Thought lasts around seven to
eleven years of age, and is characterized by the development
of organized and rational thinking.
 Piaget considered the concrete stage a major turning point in
the child's cognitive development, because it marks the
beginning of logical or operational thought.
 The child is now mature enough to use logical thought or
operations (i.e. rules) but can only apply logic to physical
objects (hence concrete operational).

 Social and emotional development means how children start
to understand who they are, what they are feeling and what to
expect when interacting with others.
 It is the development of being able to: Form and sustain
positive relationships. Experience, manage and
express emotions, Explore and engage with the environment.
Socio Emotional Development

 Morality is our ability to learn the difference between right or
wrong and understand how to make the right choices.
 Between the ages of 2 and 5 years, many children start to
show morally-based behaviors and beliefs.
 According to Kohlberg, young children at this age base their
morality on a punishment and obedience orientation.
Moral Development

 Adolescence is defined as the stage of life that begins at the
onset of puberty, when sexual maturity, or the ability to
reproduce is attained.
 The social and psychological dimensions of the adolescent
experiences depends on the cultural context.
Challenges of Adolescence

 Adolescence is characterized by dramatic physical changes in
growth rate and sexual characteristics. It is a gradual process.
 The hormones released during puberty result in the
development of primary and secondary sexual charaterstics.

 Physical development is accompanied by a number of
psychological changes.
 Around puberty adolescents show an increase in interest in
members of the opposite sex and in sexual matters and a new
awareness of sexual feelings develops.
 The development of a sexual identity defines the sexual
orientation and guides sexual behaviour.
 Another important developmental task during adolescence is
accepting one’s physical self/ maturity.
Psychological Changes

 Cognitive development refers to the development of the
ability to think and reason.
 Adolescence marks the beginning development of more
complex thinking processes (also called formal logical
operations) including abstract thinking (thinking about
possibilities), the ability to reason from known principles
(form own new ideas or questions), the ability to consider
many points of view according to varying criteria (compare or
debate ideas or opinions), and the ability to consider the
process of thinking.

 Adolescent begin to think about ideal characteristics for
themselves and others and compare themselves and others
with these ideal standards.
 Hypothetical Deductive Reasoning is the ability to think
scientifically through generating predictions, or hypotheses,
about the world to answer questions. The individual will
approach problems in a systematic and organized manner,
rather than through trial-and-error.

 Imaginary audience. The imaginary audience refers to a
state where an individual imagines and believes that
multitudes of people are enthusiastically listening to or
watching him or her.

 The Personal Fable is a belief held by many adolescents telling
them that they are special and unique, so much so that none of life's
difficulties or problems will affect them regardless of their behavior.
 This is part of the adolescent’s egocentrism that involves their sense
of uniqueness.

 Delinquency may be defined as anti-social behaviour
According to this definition delinquency means a behaviour
which is unsocial or anti-social in nature.
 Delinquency refers to certain offences committed by
adolescent, which when committed by adults would be
described as crime.
 s
Some Major Concern

 It is very often found that he or she has not learnt to
distinguish between right and wrong conduct.
 Delinquency is often associated with low parental support,
inappropriate discipline and family discord.
Some Major Concern

 Substance Abuse - Substance abuse describes a pattern of
substance use leading to significant problems or distress such
as failure to attend school, substance use in dangerous
situations, substance-related legal problems, or continued
substance use that interferes with friendships and/or family
relationships.
 Substance abuse, as a disorder, refers to the abuse of illegal
substances or the abusive use of legal substances.
Some Major Concern

 Eating Disorder
 Anorexia nervosa is an eating disorder in which a person
intentionally limits the intake of food or beverage because of a
strong drive for thinness and an intense fear of gaining
weight.
Some Major Concern

 Eating Disorder
 Bulimia nervosa is an eating disorder in which a person eats
excessive amounts of food in a short period of time (binge
eating), with a sense of lack of control over eating, and then
engages in compensatory behaviors to prevent weight gain,
such as vomiting, other medications, fasting or excessive
exercise.
Some Major Concern

 It is the period in the human lifespan in which full physical
and intellectual maturity have been attained.
 Adult is someone who is responsible, mature, self-supporting
and well integrated into society.
Adulthood

 The best time for some of the most important life events (i.e.
marriage, job, having children) might be quite different in
different cultures but within a culture there is similarity in the
course of adult development.
 In early adulthood, the two major tasks are-
a) Exploring the possibilities for adult living
b) Developing a stable life structure.
Adulthood

 Career and Work
 Entering work life is a challenging event in anyone’s life.
 It is the beginning of new roles and responsibilities.
 Developing and evaluating a career becomes an important task of
adulthood.
Adulthood

 Marriage, Parenthood and Family
 There are lots of adjustment a young adult has to make when
entering into marriage.
 Becoming a parent can also be a stressful transition in young
adults.
Adulthood

 Despite the stresses associated with parenting, it provides a
unique opportunity for growth and satisfaction and is
perceived as a way of establishing concern and guiding the
next generation.
 Physical changes in middle adulthood are caused by
maturational changes in the body. They are-
a) decline in vision
b) sensitivity to glare
c) hearing loss
 d) changes in physical appearance.
Adulthood

 Traditionally, the age of retirement was linked to old age.
Now, that people are living longer, age of retirement from
work is changing, and the cut-off point for the definition of
‘old age’ is moving upward.
Old Age

 Challenges in old age are-
a) retirement
b) widowhood
c) illness
d) death in the family.
 Old age people are competent and hence valued by society in
many walks of life.
Old Age

 In old age feeling of loss of energy and dwindling of health
and financial assets, lead to insecurity and dependency.
 Support from children, grandchildren and friends can help the
individual to cope up with various struggles of life.
Old Age
