CHAPTER PREVIEW 2
Discuss how as the thought processes of children develop, they begin to think, communicate and relate with others, and solve problems.
Section 3: Parenting Styles and Social Development
CHAPTER PREVIEW 3
Describe the social decisions children face as they grow and progress through the stages of life.
SECTION 1: NATURE AND NURTURE
• Developmental psychology—the study of changes that occur as an individual matures.
• Developmental psychologists study:
– Continuity versus stages of development
– Stability versus change
– Nature versus nurture
SECTION 1Newborns• Babies are born with certain reflexes:
– Grasping reflex
– Rooting reflex
SECTION 1: PHYSICAL DEVELOPMENT• Within two years an infant transforms into
a little boy or girl with many capabilities.
• This is due to:
– Maturation
– Learning—a relatively permanent change in behavior that occurs as a result of experience.
SECTION 1• Psychologists have been able to develop an
approximate timetable for maturation, which helps doctors and other professionals spot problems.
• Each child is unique, so the age range on some milestones varies.
Physical and Motor Development
SECTION 1Perceptual Development• Newborns have mature perception skills.
– They prefer human faces and patterned materials.
– They benefit from being held and touched by their parents.
– Infants older than 6 months display depth perception.
SECTION 1The Development of Language• Chimpanzees develop at least as far as a
2 year-old-human; however, they cannot apply grammatical rules.
• Grammar—a set of rules for combining words into phrases and sentences to express an infinite number of thoughts that can be understood by others.
SECTION 1The Development of Language (cont.)
• Psychologists argue over whether language is reinforced or inborn.
• Some people also claim that there is a window of opportunity for learning language.
SECTION 1• Steps to learning language:
– A person must learn to make signs, either by hand or mouth.
– He or she must learn the meaning of the signs.
– Then he or she must learn grammar.
The Development of Language (cont.)
SECTION 1• At the age of 2, a child’s language is
known as telegraphic speech—the kind of verbal utterances in which words are left out, but the meaning is usually clear.
• Once children begin to learn grammatical rules, they tend to overgeneralize those rules until they truly understand them.

SECTION 2-MAIN IDEAMain Idea
As the thought processes of children develop, they begin to think, communicate and relate with others, and solve problems.
SECTION 2-KEY TERMSVocabulary
• schema
• assimilation
• accommodation
• object permanence
• representational thought
• conservation
• egocentric
• imprinting
• critical period
SECTION 2-OBJECTIVESObjectives
• Summarize the cognitive-development theory.
• Discuss how children develop emotionally.
SECTION 2Cognitive Development
• Jean Piaget believed that intelligence, or the ability to understand, develops gradually as the child grows.
• Intellectual development involves:
– Quantitative changes (growth in the amount of information)
– Qualitative changes (differences in the manner of thinking)
Jean Piaget
SECTION 2Cognitive Development (cont.)
• A schema is a conceptual framework a person uses to make sense of the world.
• Assimilation and accommodation work together to produce intellectual growth.
• When events do not fit into an existing schema, a new one must be formed.
SECTION 2• Object permanence is a big step in a
child’s second year of life.
• Achieving object permanence usually signifies representational thought.
• The realization of conservation occurs between the ages of 5 and 7.
• Before the age of 5, children are egocentric.
Cognitive Development (cont.)
Tasks to Measure Conservation
SECTION 2• Piaget’s stages of cognitive development:
– Sensorimotor stage—the infant uses schema that primarily involve his body and sensations.
– Preoperational stage—the child begins to use mental images and symbols to understand things.
Cognitive Development (cont.)
SECTION 2
– Concrete operations stage—children are able to use logical schemas, but their understanding is limited to concrete objects.
– Formal operations stage—the person is able to solve abstract problems.

SECTION 2Emotional Development
• Konrad Lorenz experimented with baby geese.
• He learned that 13 to 16 hours after birth is a critical period in which the animals imprint on the first thing they see (usually their mother).
SECTION 2Emotional Development (cont.)
• Harry Harlow concluded that monkeys clung to their mothers because of the need for contact comfort, not necessarily food.
• Some psychologist also believe that human babies form an attachment to their mothers around 6 months.
SECTION 2• Stranger anxiety—the fear of strangers
that infants commonly display.
• Separation anxiety—distress that is sometimes experienced by infants when they are separated from their primary caregivers.
Emotional Development (cont.)
SECTION 2• Mary Ainsworth and John Bowlby devised
a technique called the Strange Situation to measure attachment.
Emotional Development (cont.)
SECTION 2• Patterns of attachment include:
– Secure attachment
– Avoidant attachment
– Resistant attachment
– Disorganized attachment

• Freud’s theory of psychosexual development:
– Oral stage
– Anal stage
– Phallic stage
– Latency stage
– Genital stage
Freud’s Stages of Psychosexual Development
SECTION 3
– During the phallic stage, the child wants to claim the parent of the opposite sex for him or herself, but then begins the process of identification (a child adopts the values and principles of the same-sex parent).
– During the latency stage, the child learns the process of sublimation.
Social Development (cont.)
SECTION 3• Erikson’s theory of psychosocial
development is based on life periods in which an individual’s goal is to satisfy desires associated with social needs.
Social Development (cont.)
Erikson’s Stages of Psychosocial Development
SECTION 3• Freud and Erikson believe that learning
social rules is innate.
• Many psychologists believe that that social development is a matter of conditioning and imitation.
Social Development (cont.)
SECTION 3• Cognitive theorists view social development
as a result of a child’s acting on the environment and trying to make sense out of his experience.
• Game playing is one way that children learn such as role taking.
Social Development (cont.)
SECTION 3• Lawrence Kohlberg conducted studies to
show how important being able to see other people’s points of view is to social and moral development.
Social Development (cont.)
Kohlberg’s Stages of Moral Development
SECTION 3• Stages of moral development:
– Stage one—Children are egocentric.
– Stage two—Children have a better idea of how to receive rewards as well as to avoid punishment; they act in terms of consequences.
– Stage three—Children become acutely sensitive to what other people want and think.
Social Development (cont.)
SECTION 3
– Stage four—Children are concerned with law and order and less with approval of others.
– Stage five—People are concerned with whether the law is fair or just.

FIGURE 1Physical and Motor DevelopmentAlthough different infants achieve milestones in motor development at slightly different ages, all infants achieve them in essentially the same order. This chart shows the average ages when milestones are usually achieved.
FIGURE 2The Visual Preferences of AdultsThree- or four-month-old infants show a strong preference for faces and patterns, suggesting that infants are born with and develop visual preferences.
FIGURE 3The Flowering of LanguageBetween the ages of 2 and 5, the typical child learns an average of 10 words a day–nearly one word every hour awake!
FIGURE 4Tasks to Measure ConservationThe concept of conservation can be used to show that children think less logically than adults do. Children in the preoperational stage so not understand that the property of a substance remains the same although its appearance may change.
FIGURE 5Piaget’s Stages of Cognitive DevelopmentPiaget stressed that the active role of the child in gaining knowledge. He also stressed the differences in the way a child thinks during different stages of maturity.
FIGURE 6Freud’s Stages of Psychosexual DevelopmentAccording to Freud, there is often conflict between child and parent. The conflict occurs because the child wants immediate gratification of needs while the parent restricts that gratification in some way.
FIGURE 7Erikson’s Stages of Psychosocial DevelopmentAccording to Erikson, a child encounters a psychosocial challenge at each stage. If the child successfully resolves the issue, the child develops a positive social trait and progresses to the next stage.
FIGURE 8Kohlberg’s Stages of Moral DevelopmentEach stage of Kohlberg’s theory is cognitively more complex than the last.
PROFILE
Jean Piaget1896–1980
“[T]he child no longer tends to approach the state of
adulthood by receiving reason and the rules of right action
ready-made, but by achieving them with his own effort and
personal experience; in return society expects more of its new generations than mere
imitation: it expects enrichment.”
