Study Notes

Body Changes

Children become thinner as their lower body grows longer.
Well-nourished children gain about 2 kg in weight and 3 inches in height annually between ages 2 and 6.
The center of gravity shifts from the breastbone to the belly button.

Nutrition

Children need fewer calories per pound of body weight than infants.
Obesity is more common than malnutrition, particularly in low-income families.
Overfeeding is contributing to an increase in obesity-related illnesses like heart disease and diabetes.

Other Body Changes

Many children crave high-fat, high-salt, and high-sugar foods.
Adults often give in to these cravings, sometimes rewarding children with candy.
Excessive sugar intake and insufficient fiber contribute to tooth decay, a prevalent problem in developed countries.

Just Right

Some children are very particular about how their food is presented, and what food they want to eat.
This "just-right" phenomenon, while normal in children under age 6, would be considered unusual in adults.
This preference was observed in over 75% of 3-year-olds in a study.

Motor Skills

Children develop motor skills naturally through play.
By age 6, many North American children can ride tricycles, climb ladders, swing, throw, catch, and kick balls.
Practice helps develop fine motor skills involving small body movements.

Brain Development

By age 2, a child's brain is 75% of its adult weight.
Significant pruning and sprouting of dendrites have occurred by this age.
The brain reaches 90% of its adult weight by age 6.

Speed of Thought

Myelination, the fatty coating on axons, enables faster thought processing.
Myelination increases progressively, leading to faster thought processes as children age.
5-year-olds tend to be quicker than 3-year-olds, who in turn are quicker than toddlers.

Brain Lateralization

The corpus callosum, a band of nerve fibers, connects the left and right sides of the brain.
Growth of the corpus callosum improves communication between the brain hemispheres leading to greater efficiency.
Brain lateralization refers to the specialization of brain functions on each side, with one side typically dominant.

The Prefrontal Cortex

Maturation of the frontal cortex improves focus and reduces impulsiveness in children.
Before this, children may have difficulty focusing on one task or remaining quiet.
Some children exhibit perseveration, focusing on just one thought or action for too long.

Emotional Development

From ages 2 to 6, maturation of the prefrontal cortex leads to better sleep patterns, more nuanced emotions, and a decrease in temper tantrums.

Emotions and the Brain

The Limbic System plays a critical role in how emotions are expressed and controlled.
The Amygdala registers emotions, particularly fear.
The Hippocampus processes memory, especially location-based memory.
The Hypothalamus responds to amygdala and hippocampus activity and produces hormones impacting brain function.
Chronic or prolonged stress can cause emotional and cognitive impairments.

Thinking During Early Childhood (Piaget)

Preoperational thought is the stage before logical operations in reasoning.
Language enables symbolic thinking, allowing children to think beyond immediate sensory experiences.

Characteristics of Preoperational Thought

Centration: Focusing on only one aspect of a situation.
Egocentrism: Viewing the world solely from one's own perspective.
Focus on appearance: Ignoring aspects not readily apparent.

More Characteristics of Preoperational Thought

Static reasoning: Believing that nothing changes.
Irreversibility: Inability to "undo" a change.
Conservation: The understanding that the amount of a substance remains the same despite changes in appearance.
Animism: The belief that natural objects have life.

Tests of Various Types of Conservation

Various tests were created to demonstrate the aspects, such as volume, number, matter, and length, illustrating this stage of development. (Examples of questions and scenarios are shown)

Cognitive development is heavily influenced by social interactions.
Apprentice in thinking: learning from more skilled individuals.

Zone of Proximal Development (ZPD)

ZPD is the skills individuals can achieve with assistance but not independently.

Scaffolding

Scaffolding is temporary assistance tailored for the learners' needs in order for them to master tasks.

Private Speech

Private speech is the internal dialogue occurring when individuals talk to themselves, either silently or out loud.

Social mediation is the process by which people communicate to expand understanding, leading to new understanding.

Children's Theories

Theory of mind: The process by which children understand other people's thoughts and beliefs.

Piaget vs Vygotsky

A comparison of their theories, highlighting key distinctions.

Language

Language is crucial to all aspects of cognition in early childhood.
Early childhood is a critical time for mastering vocabulary, grammar, and pronunciation.
By age 6, the average child knows over 10,000 words.

Language Development

Naming explosion: Expanding the use of words, including verbs, adjectives, and more complex words.
Fast-mapping: Quick learning of new words through tentative placement in mental categories.

Basic Grammar

Grammar encompasses the structure, techniques, and rules used to communicate meaning, including word order, prefixes, suffixes, intonation, and emphasis.
Overregularization: Applying grammatical rules rigidly to exceptions, which may make speech seem more "regular" than it is.

Early Childhood Education: Child-Centered Programs

These programs emphasize children's innate desire to learn, and focus on play and self-directed exploration.
They respect individual expression and learning styles.
Examples cited include the Reggio Emilia approach and Montessori schools.

Early Childhood Education: Teacher-Directed Programs

These programs prioritize academics and teacher-directed instruction.
Students are specifically taught letters, numbers, and colors.
Curriculum often separates work and play activities.

Intervention Programs

Project Head Start was a highly publicized program that aimed to raise children's intelligence through early intervention.

Injuries and Maltreatment

Accidents are a significant cause of death among young children.
Maltreatment encompasses intentional harm and neglect.
There are various types of preventative strategies and treatments.

Primary, Secondary, and Tertiary Prevention

The different preventative strategies used to reduce negative occurrences and encourage positive development.

Maltreatment: Signs

Physical injuries that appear questionable or don't fit a typical accident description.
Behavioral indicators like unusual play, withdrawal, or hypervigilance.
Emotional indicators like fear in response to caregivers.

Consequences of Maltreatment

Children who are significantly maltreated experience negative impacts in all aspects of their lives - physically, academically, and socially.

Three Levels of Prevention

Strategies focused on the different stages of prevention are introduced to address maltreatment, from primary to tertiary preventive strategies.

Foster Care and Kinship Care

Legal systems that remove a child from harmful situations.
