HOW IS CHILD DEVELOPMENT A SCIENCE?

• Importance of Research—

– Objective & systematic

– Reduces likelihood information is based on

• Personal beliefs

• Opinions

• Feelings

Importance of Research

• Scientific Method

– Conceptualize or identify a problem

– Refer to a theory (set of ideas that predict)

– Develop a hypothesis (testable assumption)

– Collect the data (to test the hypothesis)

– Analyze the data (by statistical methods)

– Draw conclusions

– Compare to other research outcomes

What Characterizes Development?

Biological, Cognitive, & Socioemotional Development

• Human development combination of:

– Physical Development

• Physical changes in a person

– Cognitive Development

• Changes in thought, intelligence, & language

– Psychosocial Development

• Changes in personality, emotions, relationships

What Characterizes Development?

Periods of Development

• Developmental period – Time frame in a person’s life that is characterized by

certain features

– Prenatal period

• Conception to birth

– Infancy

• Birth - 18 or 24 mo’s

– Early childhood

• End of infancy to age 5 or 6

– Middle and late childhood

• 6 - 11 yrs of age

What Characterizes Development?

Periods of Development

– Adolescence

• Transition from childhood - early adulthood

• Approximately 10 - 12 to 18 - 22 years

– Early adulthood

• Late teens or early twenties through the thirties

– Middle adulthood

• Approximately 40 - 60 years

– Late adulthood

• 60’s or 70’s until death

Issues in Development

• Nature-Nurture issue

– Nature

• Influences of biological inheritance

• Development seen as orderly

– Nurture

• Influences of environment

• Influenced by social experiences

• Deprivation or enrichment have impact

What Characterizes Development?

• Nature-Nurture issue

– Which has the greatest influence, & how do the two interact?

Issues in Development

Images of Child Development

• Jim & Jim Twins

– Identical twins separated after birth

– Identical lifestyles after 39 yr’s apart

• Both:

– Part-time deputy sheriffs

– Chewed fingernails

– Dogs named Toy

– Sons named: James Alan, James Allan

What is the Evolutionary Perspective?

Images of Child Development

• Minnesota Study of Twins Reared Apart

– From all over world

– Asked 15,000 questions

– Other twin’s similar outcomes

• Why?

What is the Evolutionary Perspective?

Other Explanations

• Similarities just due to genetics?

• Other factors?

Other Explanations

• Adopted by parents with similar backgrounds

• Grew up in same generation

• Grew up in same culture

Nature-Nurture Interaction

• Theory with 3 ways heredity predisposition affect environment

• Heredity

• 1. Passive genotype-environment

– Early childhood

• Parents are musical

– Genes for being musical

– Environment musical

» More likely to excel due to nature & nurture

Environment

Nature-Nurture Interaction

• 2. Evocative genotype-environment

– Whole Life

• Jack social (father)

• Friends of mine gave positive feedback

• Reinforced to develop heredity, social skills

Nature-Nurture Interaction

• 3. Active genotype-environment

– Until 8-9 yrs.

• Related to their skill chose environment

– Musical older children pursue band

» Experience is directed by genotype (genes)

Epigenetic View http://www.youtube.com/watch?v=kp1bZEUgqVI

Nature-Nurture Interaction

• Heredity Environment

• Epigenetic view

– Obesity may activate genes for diabetes

– Behaviors may turn genes on or off.

Issues in Development

• Do we have:

• Continuity-discontinuity issue

– Continuity

• Gradual, continuous changes

– Discontinuity

• Distinct stages, abrupt changes

• Early-later experiences

– Hotly debated

– Malleable or resilient to experiences?

What Characterizes Development?

• Continuity vs discontinuity

Discontinuity

Continuity

Critical & Sensitive Periods of Development

• Critical periods

– Mark the time when environmental influences have the greatest impact on development.

• Permanent consequences

• Ex: Terterogens

– Damage done from drinking, etc.

» Critical period of development of fetus

» Between 2 - 8 weeks

Critical & Sensitive Periods of Development

• Sensitive Periods

– Compensatory mechanisms if development does not take place during a particular time.

• Young children most sensitive to learning language

– Learn language easily

• Abusive childhood

– Can resolve issues in adulthood

• Wide range of theories on child development

– Psychoanalytic perspective

– Learning perspective

Theories of Development

PSYCHOANALYTIC PERSPECTIVE

Psychoanalytic Perspective

Sigmund Freud Erik Erikson

Psychoanalytic PerspectiveFreud

• Psychoanalytic theories

• Freud born 1856 – 1939, Austrian

• Theory developed in early 1900’s– Behavior affected by

• Underlying emotions

• Unconscious mind

What Characterizes Development?

Personality DevelopmentSigmund Freud

• Personality developed around 3 components

• Id – Unconscious instincts

– Infants

• Ego – Executive branch of mind, deals with reality

– Ages 2 – 3

• Conscious awareness begins

• Superego– Moral branch of mind, one’s ‘conscience’

– Ages 3 – 6

Psychoanalytic PerspectiveFreud

Freud’s Stages

Oral: Birth to 18 monthsAnal: 18 months to 3 years

Phallic: 3 to 6 years(Oedipus complex)

Latency: 6 years to pubertyGenital: Puberty onward

What Characterizes Development?

Psychoanalytic Perspective

Psychoanalytic PerspectiveErikson

• Freud

– Childhood most important

• Erikson

– Change occurs throughout life

• Psychosocial theory (Eric Erikson)

– German, 1902 - 1994

• 8 stages

• Each stage

– Unique crisis to resolve

– Developmental task

What Characterizes Development?

Psychoanalytic Perspective Erikson

Initiative vs. guilt

Generativity vs. stagnation

Early childhood

Integrity vs. despair

Intimacy vs. isolation

Industry vs. inferiority

Autonomy vs. shame and doubtInfancy: 1 to 3 years

Middle adulthood

Late adulthood

Middle and late childhood

Early adulthood

Trust vs. mistrustInfancy: 1st year of life

Identity vs. identity confusionAdolescence

Psychoanalytic Perspective Erikson

• Learn from Erikson’s stages:

– Nurture infants to:

• Develop trust

• Encourage & monitor autonomy

– Encourage initiative

• Freedom to explore their world

– Promote industry in elementary years

• Nurture motivation for mastery & curiosity

– Stimulate adolescent identity exploration

• Self-exploration

LEARNING PERSPECTIVEBehaviorism

Learning Perspective

Pavlov Watson Skinner

Bandura

Behavioral and Social Cognitive Theories

• Behaviorism

– Development is observable

– Behavior learned from experiences

– Scientific measurements possible

– Change environment to affect behavior

• Example?

Caring for Children

Learning Perspective

• Classical Conditioning, 1901

– I. Pavlov, Russian physiologist, 1849 - 1936

– Neutral stimulus acquires ability to produce response originally produced by another stimulus

• Dogs salivated to food

• Pairing food with bell produces salivation

• Sound of bell will produce salivation without food

Caring for Children

Behavioral and Social Cognitive Theories

• Classical conditioning

– J. Watson, American, 1878 - 1958

– Experiment:

• Little Albert & white rat

– Generalizing fear as an involuntary response

Caring for Children

Behavioral and Social Cognitive Theories

• Operant Conditioning

– B.F. Skinner, American, 1904 - 1990

– Consequences of behavior

• Change probability of behavior’s occurrence

• Use of punishments & rewards

– Shapes behavior & development

Behavioral and Social Cognitive Theories

• Social Cognitive Theory

• A. Bandura, American, 1925 - – Observational learning

• Modeling – Imitation

– Behavior, environment, & cognition

• Key factors in development– Father aggressive

» Effect development?

Caring for Children

COGNITIVE PERSPECTIVE

Cognitive Perspective

VygotskyPiaget

Cognitive Theories

• Piaget

• Born in Switzerland 1896 - 1980

• Cognitive development theory

– Children actively construct their understanding of the world

– 4 stages of cognitive development

Caring for Children

Cognitive Development TheoryPiaget

Birth to 2 yrs

Sensorimotor Uses senses and motor skills, items known by use; object permanence

2 - 7 yrs Pre-operational Symbolic thinking, language used; egocentric thinking, imagination/ experience grow, child de-centers

7 - 11 yrs Concrete operational

Logic applied, objective/rational interpretations; conservation, numbers, ideas, classifications

11 yrs on

Formal operational

Thinks abstractly, hypothetical ideas; ethics, politics, social/moral issues explored

Caring for Children

Cognitive Theories

• Born in Russia, 1896- 1934 (same year as Piaget)

• Sociocultural theory (L. Vygotsky)

– Social & cultural interaction

• Guide cognitive development

– Child needs interaction

• With more skilled adults & peers

– Interactions teach skills

• How to learn

– Memory, attention, reasoning involves learning to use society’s inventions

Caring for Children

Vygotsky’s Sociocultural Cognitive Theory  

• Emphasizes how culture & social interaction guide cognitive development

BIOLOGICAL & ECOLOGICAL PERSPECTIVES

Biological & Ecological Perspectives

Lorenz

BronfenbrennerBowlby

Biological & Ecological Perspectives

• Ethological theory

– Behavior influenced by biology

– Critical (sensitive) periods for learning

– Lorenz experiment:

• Imprinting

– Attached to 1st object moving object seen

– Bowlby:

• Attachment to caretaker important 1st yr of life

• Affects entire life

• Can be + or -

Caring for Children

Bioecological Theory

• U. Bronfenbrenner (1917- 2005)

– Government

– Schools

– Health Schools

– Social

Bioecological Theory

• Microsystem:

– Individual helps form

• Includes family, peers, school, & neighborhood.

• Mesosystem:

– Interrelationship between microsystems

• Family to school experiences

Bioecological Theory

• Exosystem:

• Links between a social setting (no control)

– &

• Individual's immediate context.

• Child's influenced, mother's work

– Requiring travel, might cause conflict with husband & change interaction with child.

Bioecological Theory

• Macrosystem:

• Culture in which individuals live.

– Developing & industrialized countries, socioeconomic status, poverty, & ethnicity.

• Chronosystem:

– Patterning of environmental events & transitions over life, as well as sociohistorical circumstances.

• Divorces is one transition.

CHILD DEVELOPMENT RESEARCH

Ethics

• Conducting ethical research

– Protect rights of research subjects

• Do no harm

• informed consent

– Parent & child

• Deception

– Conduct debriefing

• Anonymity

– Respect confidentiality

Caring for Children

Research Methods

• Research designs (3)

– 1. Descriptive research: observe and record

• Naturalistic Observation

• Survey

• Case Study

– 2. Correlational research: measure strength of association

• How 2 or more variables relate to each other

Caring for Children

Research Methods

• 3. Experimental research

– Behavior manipulated, change measured

– Demonstrates cause and effect

– Independent variable (gets manipulated)

– Dependent variable (gets measured)

– Control group (forms baseline measure)

– Experimental group (gets manipulated)

– Random assignment (assignment by chance)

Caring for Children

Research Methods

• Observation

– Laboratory or naturalistic observation

• Survey & interview

• Standardized test – uniform procedures

• Case study – in-depth on individual

• Physiological measures

– fMRI (electromagnetic waves used)

Caring for Children

Research Methods

• Time span of research

– Cross-sectional approach

• Several groups (usually different ages) compared at one time

– Longitudinal approach

• Follows same group over long period of time (usually years)

Caring for Children

Minimizing Bias

• Gender bias

– Preconceived ideas about female & male abilities, magnifying differences found

Caring for Children

• Cultural & ethnic bias

– Excluding minorities, preconceived ideas

• Ex: This population not ‘average’

• Ethnic gloss

– Use of ethnic label portraying ethnic groups as more homogeneous than they really are

• Are all Germans the same?

Minimizing Bias
