Development Flashcards
How does the early brain develop ?
3/4 weeks - Long neural tube can be seen (split into forebrain, midbrain, hindbrain)
5 weeks - Forebrain & Hindbrain split further : forebrain into anterior & posterior; Hindbrain down the middle
6 weeks - Cerebellum
20 weeks - Medulla
Role of Cerebellum ?
Controls Physical skills and motor commands from the nervous system (Eg. balance, crawling, walking)
Role of Medulla ?
Connects brain to spinal cord and controls involuntary functions (Eg. Breathing, Sneezing, heart rate, blood pressure)
What are the 4 stages of Development ?
Sensorimotor, Pre-Operational, Concrete Operational, Formal Operational
What happens in Sensorimotor Stage ?
(0-2 yrs)
Use senses to explore - grasp and suck
Develop object permanence at 6m (understand objects still exist even when they cannot see them)
What is Object Permanence ?
Something a child develops at 6 months which means they can understand objects still exist even when they cannot see them
What happens in Pre-Operational ?
(2-7 yrs)
- Symbolic play and thinking
- Animism
- Transductive reasoning
- Centrated
- Lack conservation
- Egocentric
Animism ?
When children believe objects behave as if alive
Transductive Reasoning ?
When children don’t understand cause and effect
Centration ?
When children can only focus on one aspect of an object at a time
Lack of Conservation ?
Children are unable to realise things remain constant despite visible change
Egocentrism ?
Children think others see the world as they do, cannot imagine point of view of others
What happens in Concrete Operational Stage ?
(7-12 yrs)
- Use concrete objects to apply rules and strategies
- Decentrated
- Can conserve
- Can classify world around them
What happens in Formal Operational Stage ?
(12+)
-Hypothetico-deductive reasoning (can think about hypothetical ideas and consider outcomes)
- Can think about complex issues like morality
- Empathise
- Solve problems in an abstract way
- Think Logically
Hypothetico-deductive reasoning ?
People can think about hypothetical ideas and consider outcomes
Schema ?
Mental packets of information made up from past experiences that provide a framework to understand the world.
Assimilation ?
Incorporating new experiences and information into existing schema
Accommodation ?
A schema no longer works and has to be changed to deal with new experience
Equilibrium ?
A good state of mental balance that comes from a child’s schema working well and explaining what they experience.
Aim of Piaget & Inhelder (1956) 3 mountains study ?
To investigate whether children under the age of 7 can see the world from another person’s pov
