Study Notes
Brain Development in Early Childhood
- Brain rapidly grows to 20-25% of adult weight during ages 2-6.
- Myelination speeds up neuron communication, improving motor skills.
- Brain hemispheres specialize (lateralization): left for language, right for emotions.
- Corpus callosum myelination enhances communication between hemispheres, leading to handedness.
Piaget's Preoperational Stage
- Stage lasts from age 2 to 7, with two sub-stages.
-
Symbolic Function (Ages 2-4):
- Centration: Focus on one aspect.
- Conservation: Inability to understand unchanging properties.
- Egocentrism: Inability to see from others' perspectives.
- Animism: Belief inanimate objects have human qualities.
- Irreversibility: Changes are not reversible.
-
Intuitive Thought (Ages 4-7):
- Curiosity increases, but reasoning is intuitive.
- Artificialism: Explaining natural events as human actions.
- The three-mountain task demonstrates egocentrism by testing children's understanding of different perspectives.
Criticisms of Piaget's Theory
- Underestimates children's abilities.
- Lacks cultural considerations.
Vygotsky's Theory of Cognitive Development
- Emphasizes social learning.
- Zone of Proximal Development (ZPD): Tasks children can perform with guidance.
- Scaffolding: Support from more knowledgeable individuals.
- Language is key for cognitive development, especially private speech (seen as self-regulation).
- Vygotsky's approach contrasts with Piaget's emphasis on developmental stages and maturation.
- Vygotsky emphasizes social interaction while Information Processing focuses on internal cognitive processes.
Language Development (Ages 2-6)
- Vocabulary rapidly increases from 500 words at age 2 to over 12,000 by age 6.
- Telegraphic speech (simple two-word phrases) progresses to complex sentences.
- Overgeneralization: Applying grammatical rules to irregular cases (e.g., "runned").
- Categorization: Grouping objects by shared traits.
- Fast mapping: Learning new words quickly.
Barriers to Free Play
- Limited free time due to structured activities.
- Screen time replaces physical play.
- Lack of green spaces and unsafe/inaccessible play areas.
- Parental fear of abduction/injury.
- Social and economic factors.
- Video games lack the creativity and physical activity of free play.
Childhood Obesity and BMI
- Body Mass Index (BMI) measures body fat.
- Childhood obesity is linked to psychological and chronic health risks (e.g., depression, diabetes, heart disease, asthma).
- Prevention involves healthy eating, promoting physical activity, limiting screen time, and family support.
