Chapter 2 Flashcards
Development
- The pattern of biological, cognitive, and socio-emotional changes that begins at conception and continues through the lifespan.
- Interactional processes and time periods (all intertwined).
Biological Processes
- Genetic inheritance plays a large part.
- Produce changes in the child’s brain development , height + weight gains,
motor skill changes, and
puberty (hormonal changes)
Cognitive Processes
Involves changes in child’s thinking, intelligence. and language acquisition.
Socio-emotional Processes
Involves changes in a child’s relationship with others, emotions, and personality.
Periods of Development (PoD)
- Infancy
- Early Childhood
- Middle + Late Childhood
- Adolescence
Infancy (PoD)
Extends from birth to 18 months.
- Activities include language development, symbolic thought, sensorimotor coordination, and social learning.
- Develop emotional bonds, non-verbal communication, language expression, motor exploration of the physical environment.
- Learn that their behaviours can = reward
- Time of extreme dependence on adults.
Early Childhood (PoD)
Extends from the end of infancy to about five years (pre-school years).
- Children become more self-sufficient, develop school readiness skills, and spend time with peers.
- Significant development of communication and language skills, grammar, vocab.
- Physical changes include increased energy and play.
- Self-centred impulses.
- Imaginative play, make-believe, fantasy.
Middle + Late Childhood (PoD)
Extends from about age 6 to 11 (elementary school years).
- Focus less on imaginary and more on real world.
- Children master the fundamental skills of reading, writing, and maths.
- Self-control increases as children interact with a wider social world.
- Start to compare their performance with others
Adolescence (PoD)
Begins around ages 10-12 and ends in the late teens (high-school years).
- Rapid physical changes (height, weight, and sexual functions), desire for independence and identity, and development of abstract reasoning skills.
- Ability to think logically improving, but prefrontal cortex not fully developed.
- Can understand figurative language, use speech that is not literal.
- Develop views and opinions different from parents - increased independence.
- Can have complex conversations.
- Spend more time with friends than family.
Nature vs. Nurture
Nature:
- refers to an organisms biological influence.
Nurture:
- refers to environmental influences.
Both argue about which is the most important influence on development.
Epigenetic View
- View on the Nature vs. Nurture debate.
- Development is seen as an ongoing, bidirectional interchange between heredity and the environment.
Continuity vs. Discontinuty
The issue regarding whether development involves gradual, cumulative change (continuity) or distinct stages (discontinuity).
Early vs. Later
Involves the degree to which early experiences (especially infancy) OR later experiences are the key determinants of the child’s development.
Developmentally Appropriate Teaching Practice
Teaching at a level that is not too difficult and stressful nor too easy and boring.
Splintered Development
The circumstances in which development is uneven across domains.
Development is complex, there will be students at different levels and strengths in different areas.
- ex. student might be strong in maths but poor in writing, strong academically but lower level socioemotional (rejected by peers - needs to learn to manage emotions, needs help socially)
The Neuroconstructivist View on Cognitive Development.
Emphasizes that brain development is influenced by both biological processes and environmental experiences.
- The brain has plasticity and depends on experience.
- Brain development is linked closely with cognitive development.
Myelination
The process of encasing many cells in the brain with a myelin sheath.
- The myelin sheath increases the speed at which information travels through the nervous system.
Brain Development in Middle + Late Childhood
Total brain volume stabilizes.
- Prefrontal Cortex
- Synaptic Pruning
Prefrontal Cortex
(middle +late childhood)
The front region of the frontal lobes; involved in reasoning, decision making, and self-control.
- Brain pathways and circuitry in the prefrontal cortex continue to increase.
- Changes/advances in the prefrontal cortex are linked to a child’s improved attention, reasoning, and cognitive control.
- Prefrontal cortex orchestrates the function of other brain regions during development –coordinates which neural connections are most effective for problem solving.
Synaptic Pruning
(middle +late childhood)
Increased focal activation = increased cognitive performance.
- Attention, reducing interfering thoughts, inhibiting motor actions, increased flexibility of thought.
As the brain changes/develops, it changes from diffuse, larger areas to more focal, smaller areas.
Brain Development in Adolescence
- Continued ‘pruning’ of synapse connections.
- Adolescents have fewer, more selective, more effective connections between neurons than they did as children.
- Activities adolescents choose to engage in or not engage in influence neural connections (which will be strengthened and which will disappear).
- Corpus Callosum
- Limbic System
- Amygdala
- The prefrontal cortex is NOT developed enough to control emotions (brain area responsible for control still developing = risky behaviour).
Corpus Callosum
(adolescence)
The brain region where fibres connect the left and right hemispheres.
- Thickens and increases ability to process info.
Limbic System
(adolescence)
Brain region that is the seat of emotions (amygdala) and in which rewards are experienced.
- Emotions
- Almost completely developed
