1. What is human behavior?
The capacity of mental, physical, emotional, and social
activities experienced during the 5 stages of human being’s lifeprenatal, infancy, childhood, adolescence, and adulthood.
Includes the behaviors as dictated by culture, society, values,

language and reasoning
are considered
development
MATURATION
Innately determined
sequence of growth and
bodily changes that are
relatively independent of
environmental events
3.
Stages in Life Span:
1. Pre – natal – conception to birth
2. Infancy – birth to end of the second week
3. Babyhood/Childhood – end of the second
week till end of the second year.
4. Early Childhood – 2 to 6 years old.
Childhood
5. Late childhood – 6 to 12 years old
6. Puberty / preadolescence – 10 to 13years old
7.Adolescence – 13 to 18 years old
Adolescence
8. Early Adulthood – 18 to 40 years old
9. Middle age – 40 to 60
Adulthood
10. Old age – 60 to death
4. PSYCHOLOGICAL THEORIES OF
DEVELOPMENT
PSYCHOSEXUAL THEORY OF
DEVELOPMENT
Developed by Sigmund Freud who
associated development with the sexual
activities of the child
He said that each stages of development,
one’s needs must be satisfied moderately

when there is excessive
anticipation in satisfying

elimination
Toilet Training

excessive anticipation during infancy stage
Nail biting

ELECTRA COMPLEX

22. Moral Development
Proposed by Lawrence Kohlberg
Levels of morality follow a developmental
sequence that is distinctively different
from each other. Each level contains two
stages.
1. Preconventional Morality
2. Conventional Morality
3. Postconventional Morality
23. 1. PRECONVENTIONAL MORALITY
Stage 1 Punishment-obedience orientation
Behaviors are perceived to be right when
children are able to avoid punishment
brought about by their own behavior
Stage 2 Instrumental relativism orientation
The child’s basis of moral reasoning is
based on benefit
24. 2.CONVENTIONAL MORALITY
Stage 3 Good boy/nice girl Orientation
It is other people’s perception that is
important in making moral behaviors in
this stage
The person thinks that moral behaviors
are right when he or she knows that other
will think positively of him or her in doing
th behavior.
25. 2.CONVENTIONAL MORALITY
Stage 4 Law and order orientation
There is a tendency to base moral
reasoning in the existing rules and policies
concerning the behavior.
26. 3.POSTCONVENTIONAL MORALITY
Stage 5 Social contract orientation
The person in this stage believes that rules are
made in order to protect people, therefore when
one is no longer protected the rules should be
broken.
Stage 6 Universal ethical principle
This stage depicts the internalized morality of
the person
It is no longer the society’s standards and
expectations that are used in making moral
judgment but it is the CONSCIENCE that
becomes the reference of the action.
28. 1. Intelligence and cognitive functioning develop in children.
2. Human Intelligence progresses through a series of
stages based on age.
3. In his schema, he believed that biologic changes and
maturation were responsible for cognitive development.
4. Individual reach cognitive maturity by middle to late
adolescence..
29.
30. Stages of Cognitive Development
SENSORIMOTOR (0-2 years)
Birth to two years
Function based on two aspects: sense
and motor
Infants are preoccupied with discovering
the relationships between their actions
and the consequences of these actions
32. Preoperational Stage
(2-7 years)
The children interact with their environment

necessary understanding the need of the
parent to take a rest.
33. CONCRETE OPERATIONAL
Their thinking is considered to be logical but
limited to something that is concrete in nature.
They have the difficulty of understanding
abstract concepts like love and faith
The child is able to acquire the concept of
conservation that is, the amount of substance
remains the same even when its shaped is
changed or when parts are divided into parts.
34.
35. Formal Operational
The child at this stage is able to
understand concepts that are abstract in
nature going beyond from what the child is
capable of during the concrete operational
stage
They are able to make use of their

1. ___describes decreases in mental abilities experienced by some people
in old age.
5.The attachment of the child towards the farther and the feeling of rivalry
towards the mother.
37. Nervous system-control our body function, emotions, memory, thinking and
behavior.
2 kinds of N.S.
1. Central Nervous System – nerves from the back transmit message
between the body and the brain.
2.Peripheral Nervous System - smaller nerves branch out from spinal
nerves take information from the body organs to the CNS.
II. NEURON – nerve of strings long and thin cells. It fires when stimulated.
3 types of neuron:
1. affarent neuron – sensory neurons (relay messages from the sense
organ).
2. efferent neuron – motor neuron – send signal from the brain to the glands
and muscles.
3. interneurons – transmit message between neuron to another neuron.
38. PARTS of the BRAIN
1. HINDBRAIN rear base of the skull.
Involved the main process of life.
cerebellum – controls posture and
balance.
medulla - controls breath and reflexes.
Pons – a bridge bet . Spinal and brain
produced chemicals needed for sleep.
39. 2. MIDBRAIN – small part of the brain
above the pons. Collects information from
the senses and sends it upward.
Medulla,Pons, Midbrain – Brain stem
Reticular activating system – it alert the
rest of the brain to messages coming in.
