Middle Childhood: Cognitive Development Truth or Fiction?

Don’t try the “Yes, but” defense with a 5-year old. If you did it,
you’re guilty, even if it was an accident.

Memorizing the alphabet requires that children keep 26 chunks
of information in mind at once.

Middle Childhood: Cognitive Development Truth or Fiction?
 An IQ is a score on a test.
 Two children can answer exactly the same items on an
intelligence test correctly, yet one can be above average in
intelligence and the other below average.

Middle Childhood: Cognitive Development Truth or Fiction?

Highly intelligent children are creative.

Adopted children are more similar in intelligence to their
adopted parents than to their biological parents.

Piaget’s ConcreteOperational Stage
Childhood and Adolescence: Voyages in Development, Second Edition, Spencer A. Rathus
Chapter 12
What Is Meant by the Stage of Concrete Operations?
• Beginnings of adult logic, involves tangible not abstract ideas
• Characterized by
– Reversibility and flexibility
– Less egocentric
– Decentration
Childhood and Adolescence: Voyages in Development, Second Edition, Spencer A. Rathus
Chapter 12
What Is Meant by the Stage of Concrete Operations?
• Demonstrate understanding of conservation
– Object can have several properties or dimensions
– Child can decenter and focus on more than one dimension
• Conservation of mass develops first
Childhood and Adolescence: Voyages in Development, Second Edition, Spencer A. Rathus
Chapter 12
What Is Meant by the Stage of Concrete Operations?
• Demonstrate understanding of transitivity
– If A exceeds B in some property
– B exceeds C,
– then A must also exceed C
• Assess transitivity through seriation tasks
– Requires decentration to focus on more than one dimension
• Demonstrate an understanding of class inclusion

Lessons in Observation:
Piaget’s Concrete-Operational Stage
• What is conservation?
– Why is the ability to conserve an important milestone in cognitive
development, according to Piaget?
– Describe the conservation tasks and discuss the performance of the
children depicted in the video.
– Are their responses typical of children in the concrete operational
stage? Why or why not?
• Cite specific reasons given by children in the video when they
are asked to explain “why” they thought the amount of liquid or
play dough had changed or not changed.

Lessons in Observation:
Piaget’s Concrete-Operational Stage
• Do these responses illustrate changes in the
reasoning abilities of concrete operational children as
described by Piaget?
– Include the following Piagetian concepts in your discussion:
conservation, decentration, and reversibility
• Do the children in the video use logical or intuitive
approaches to solving problems?
Childhood and Adolescence: Voyages in Development, Second Edition, Spencer A. Rathus
Chapter 12
Lessons in Observation:
Piaget’s Concrete-Operational Stage
• Are children in Piaget’s concrete operational stage
likely to be able to use their reasoning skills on
problems and ideas that they have not experienced
directly? Why or why not?
Childhood and Adolescence: Voyages in Development, Second Edition, Spencer A. Rathus
Chapter 12
Can We Apply Piaget’s Theory of Cognitive Development
to Educational Practices?
• Learning involves active discovery
– Find stimulating materials instead of imposing knowledge
• Instruction geared to student’s level
– Consider the level of cognitive development
• Encourage development of perspective taking
Childhood and Adolescence: Voyages in Development, Second Edition, Spencer A. Rathus
Chapter 12
Evaluation of Piaget’s Theory
• Piaget tended to underestimate children’s abilities
• Horizontal decalage
– Ability to master different tasks within same stage
• Cognitive development may be more continuous

Moral Development
The Child as Juror
Childhood and Adolescence: Voyages in Development, Second Edition, Spencer A. Rathus
Chapter 12
How Does Piaget View the Development of Moral Reasoning?
Two stages of moral development
• Moral Realism – ‘objective morality’
– Emerges at about age 5
– Behavior is correct when to conforms to authority or rules
• Rules are absolutes
– Punishment is inevitable
• Immanent justice or automatic retribution
• Do not excuse accidental behavior
Childhood and Adolescence: Voyages in Development, Second Edition, Spencer A. Rathus
Chapter 12
How Does Piaget View the Development of Moral Reasoning?
Two stages of moral development
• Autonomous Morality
– Emerges between ages of 9 and 11
– Social rules are arbitrary agreements that can be changed
• Circumstances can require breaking rules
– Consider the intentions of the wrongdoer
– Develops as a result of cooperative peer relationships
Childhood and Adolescence: Voyages in Development, Second Edition, Spencer A. Rathus
Chapter 12
What Is Kohlberg’s Theory of Moral Development?
• Preconventional level
– Obedience and punishment
– Instrumental orientation
• Conventional level
– Good-boy/good-girl orientation
– Law-and-order orientation
• Postconventional level
– Contractual, legalistic orientation
– Universal ethical principles orientation

What Is Meant by the Term Memory?
• Storage and retrieval of information
– Sensory Memory
– Short-term or working memory
• Auditory encoding
• Capacity 7 chunks of information achieved by adolescence
– Typical 5- or 6-year old – works on two chunks of information at a time

What Do Children Understand About the Functioning of Their
Cognitive Processes and Their Memory?

Measurement of Intellectual Development
•
Stanford-Binet Intelligence Scale (SBIS)
– Assumes intelligence increases with age
– Older child must answer more items to obtain comparable score to
younger child (mental age)
– IQ = mental age divided by chronological age x 100
– 2-year-olds to adults
Childhood and Adolescence: Voyages in Development, Second Edition, Spencer A. Rathus
Chapter 12
Measurement of Intellectual Development
•
Wechsler Scales
– Groups questions into subtests that measure different intellectual
tasks
•
Compares performance on one type of task with another
– Wechsler Preschool and Primary Scales of Intelligence (WPPSI)
– Wechsler Intelligence Scales for Children (WISC)
– Wechsler Adult Intelligence Scales (WAIS)

The Testing Controversy
•
IQ test scores
– Should not be sole criteria for placement
– Accurately measure skills necessary in today’s high tech work
•
Culture-bias versus culture-free
– Bias for African American and lower social class
– Cattell’s Culture-Fair Intelligence Test
•
Culture-free tests have not been successful
– Disadvantaged children consistently score lower
– Do not predict academic success

What Is the Relationship Between Creativity and Intelligence?
•
Moderate relationship between intelligence scores and creativity
– Sternberg’s Triarchic Theory includes creative intelligence
– Gardner’s Multiple Intelligences include creative areas
•
Explanation for lack of relationship
– Intelligence testing requires convergent thinking
– Creative thinking requires divergent thinking

Chapter 12
What Are the Roles of Nature and Nurture on the
Development of Intelligence?
•
Genetic Influences
– Measured through kinship and adoption studies
– More closely related – more similar IQ scores
– Heritability – about 45 to 60%
•
Environmental Influences
– Same studies consider

What Cognitive Skills Are Used in Reading?
•
Reading demands perceptual, cognitive and linguistic processes
– Integrate visual and auditory information
– Able to make basic visual discriminations
•
Reading to preschool children – prepares them for reading
Childhood and Adolescence: Voyages in Development, Second Edition, Spencer A. Rathus
Chapter 12
Methods of Teaching Reading
•
Word-recognition method
– Associate visual stimuli with sound of spoken word
– Acquired by rote learning
•
Phonetic method
– Associate letters with sounds they indicate – sound out words
•
Most children utilize both methods
– Word-recognition for basic sight vocabulary
– Phonetic method for decoding new words
