Copyright © 2018 Pearson Education, Inc. All Rights Reserved

From Africa to Distant Destinations

LO 1.2.1 Identify the evolution of characteristics that make modern humans distinct from their nearest great ape species.

Charles Darwin The Origin of Species

All species change through the process of natural selection

Humans, chimpanzees, and gorillas have a common ancestor

Hominins evolved into Homo sapiens

Brain size is a critical difference for humans

Babies born at earlier stage of brain development than chimpanzees or gorillas (assists with getting through birth canal)

Humans adapted to different environments and migrated

Evolution, Culture, and Child Development Today

LO 1.2.3 Apply information about human evolution to how child development takes place today.

Development is based partly on evolutionary history

Humans developed large brains

Allowed us to adapt to most environments

Allowed us to change our environment

Survival methods are passed down to children as part of culture

Natural selection and culture determines how we live

1.3 The Field of Child Development: Emergence and Expansion

Copyright © 2018 Pearson Education, Inc. All Rights Reserved

The Emergence of a Science of Child Development (1 of 3)

LO 1.3.1 Provide some reasons why the field of child development primarily focused on younger children until about the mid-20th century.

Freud’s focus on early childhood

Focus on traumatic events in childhood

Psychoanalysis was intended to bring repressed memories from the unconscious to the conscious mind

Stages

Oral

Anal

Phallic

Latency

Genital

Freud’s theory was very popular, but is no longer favored

Binet and mandatory primary school

Asked by French government to design an instrument to identify struggling students

Binet-Simon intelligence scale

General knowledge

Reasoning

Memory

Problem-solving

The Emergence of a Science of Child Development (3 of 3)

LO 1.3.1 Provide some reasons why the field of child development primarily focused on younger children until about the mid-20th century.

Hall’s preliminary attention to adolescence

Hall’s importance in psychology

First to obtain Ph.D. in U.S.

Founder of American Psychological Association

President of Clark University

Wrote first text on adolescence

Based writings on recapitulation

While no longer supported, some research confirms his ideas

Popularized the term “adolescence”

Copyright © 2018 Pearson Education, Inc. All Rights Reserved

Expansion of the Field of Child Development: Adolescence

LO 1.3.2 Describe when the field of child development began to address adolescence in a notable way, and explain why the age range that Hall had designated for adolescence has been been moved downward by contemporary researchers.

Anna Freud

Supported storm and stress period for adolescents

Erik Erikson

Proposed lifespan theory of development

Adolescence a period for establishing identity

Change in age range for adolescence

Menarche has steadily started earlier in girls

Growth in secondary education giving a natural end to adolescence when school ends

Another Expansion: Emerging Adulthood

LO 1.3.3 Explain how the field of child development has recently expanded anew to encompass emerging adulthood.

Emerging adulthood

Stage between adolescence and young adulthood

Developed countries

Reflects continuing education

People enter marriage and parenthood after mid-20s

Stage representing some separation from parents, but not clear commitment to stable roles

Developing countries

Still marry in early 20s

No continuing education

Enter adult roles earlier

Education Focus: Falling Behind? College Graduation in the United States

United States has slipped behind other developed countries in college completion

In 1995 led all countries with graduation rate of 33%

In 2012 only 4 countries fell below United States

College education the highest cost in the United States

There are economic benefits to a college education

Today’s Child Development

LO 1.3.4 Describe the cultural-developmental approach, and why developmental stages and pathways within this approach are somewhat flexible.

Has broadened its scope to include adolescence and emerging adults

Spectrum of the field

Prenatal

Infancy

Early childhood

Middle childhood

Adolescence

Emerging adulthood

Cultural-developmental framework

Study impact of culture on developmental periods

Study across diverse cultures

Highlights that cultural change can be quite rapid and many people identify with more than one culture

1.4 How We Study Child Development

Copyright © 2018 Pearson Education, Inc. All Rights Reserved

The Five Steps of the Scientific Method

LO 1.4.1 Recall the five steps of the scientific method.

Five Steps

Step 1: Identify a question of scientific interest

Step 2: Form a hypothesis

Step 3: Choose research measurement and research design

Step 4: Collect data to test the hypothesis

Step 5: Draw conclusions and form new questions and hypotheses

Table 1.4 Research Measurements: Advantages and Limitations

Measurements Advantages Limitations
Questionnaire Large sample, quick data collection Preset responses, no depth
Interview Individuality and complexity Time and effort of coding
Observations Actual behavior, not self-report Observation may affect behavior
Biological Measurements Precise data Expensive, relation to behavior may not be clear

Research Designs

LO 1.4.3 Distinguish between major types of research designs.

Table 1.5 Research Designs: Advantages and Limitations

Designs Advantages Limitations
Experiment Control, Identification of cause and effect May not reflect real life
Natural experiment Illuminates relations among naturally occurring events Unusual circumstances; rare
Correlational study Quick and inexpensive Correlations difficult to interpret
Ethnographic research Entire span of daily life Researcher must live among participants; possible bias
Case studies Rich, detailed data Difficult to generalize results

Research Focus: Darwin’s Diary: A Case Study

Darwin kept a diary of the development of his first child

Recorded cognitive, language, social, and moral development

Wanted to determine what was learned and what was innate

Research Designs in Developmental Psychology

LO 1.4.4 Describe the two major types of research designs distinctive to developmental psychology.

Cross-sectional design

People of different ages collected at a single point in time

Strengths

Affordable and timely

Limitations

Can only show correlation

Longitudinal

Same persons are followed over time

Strengths

Allows researchers to examine how people change over time

Allows researchers to gain more insight into the question of correlation or causation

Limitations

Take time, money, and patience

Attrition
