Development Flashcards
What happens at 4 weeks onwards to the brain?
Neural tube divides to:
* Hindbrain
* Spinal cord
* Midbrain
* Forebrain
What happens at 3 weeks to the brain?
- Cells come togther to form a neural tube
What happens at 6 weeks onwards to the brain?
We develop:
* Cortex
* Thalamus
Neurons and synapses form in the spinal cord - allows foetus to move around and react to environment
What happens at 15 weeks onwards to the brain?
Cerebellum forms
What happens at 6 months to the brain?
What percent is it at?
Brain is fully formed, 25% of it’s adult size
What does the cerebellum do, where is it?
- Located near spinal cord
- coordinating senses, movement, plays role in lang. and emotions
What and where is the thalamus?
- Located deep inside the brain (half is in right hemisphere and other half in left)
- Receives signals from all the other parts of the brain and sends them on
What and where is the brain stem?
- Connects brain to spinal cord
- Controls many autonomic functions ( sleeping, breathing, heart beat, blood pressure)
What and where is the cortex?
- Outer covering of the brain (folded, wrinkled part)
- All of our thinking and processing of info goes on in this part
What is nature?
Refers to things we have inheritied, something innate
What is nurture?
Refers to any other influences such as type of environment we grew up in, people, what we eat, experiences
What is a predisposition?
Born with genes
What is cognitive development?
Emergence of the ability to think and understand. Refers to mental processes, like thinking
Who was Jean Piaget?
Psychologist who studied children’s cognitive development
What is assimilation?
When you add to a schema - new info adding to an existing schema
What is accomodation?
When you change a schema/ develop a new schema to cope with a new situation - this is how we acquire knowledge about the world
What is the 1st stage of development? Age? Main features?
Sensorimotor stage (0-2yrs) - learn through senses and movement, object permanence (6 months onward) (Peekaboo game)
What is the 2nd stage of development? Age? Main features?
Pre-operational stage (2-7yrs) - Egocentric - only see things from their pov
What is the 3rd stage of development? Age? Main features?
Concrete-operational stage (7-11yrs) - Developed ability to conserve which means that knowing a quantity doesn’t change if it has been altered
What is the 4th stage of development? Age? Main features?
Formal operational stage (11+) - Able to solve problems in a systematic way
What are some limitations to Piaget’s theory?
- The way he conducted his experiments - in the conservation tasks he asked the children the same question more than once before and after the counters had been moved - this would have caused the child to change their answer bevause they believed their 1st answer was incorrect
- Piaget developed his theory using a small sample of children. They were middle class and from Switzerland. This means his findings may not tell us the cognitive development of children from different social classes or cultures
