Development (topic 1) Flashcards
Early brain development?
(20w fetus, 3-4w, 5w, 6w?)
20 weeks as a fetus:
-medulla oblongata (responsible for involuntary responses e.g. breathing)
3-4 weeks:
-the long tube develops
-three sections of the brain form: forebrain, midbrain and hindbrain
5 weeks:
-forebrain and hindbrain split further.
(forebrain: posterior and anterior)
(hindbrain: splits into half)
6 weeks:
-cerebellum develops (responsible for motor movements)
4 stages of development (Piaget)
- Sensorimotor stage (0-2yrs)
- Pre-operational stage (2-7yrs)
- Concrete operational stage (7-12yrs)
- Formal operational stage (+12yrs)
sensorimotor stage
-based on senses and motor skills
-starts with reflexes then start to control their movements
-object permanence: knowing objects still exist even when it cannot be seen
pre-operational stage
–the symbolic function stage (2-4yrs)–
-children start to copy others
-symbolic play: using objects/ideas to represent others
-animism: the belief that objects are alive
-egocentrism- views of the world through their viewpoint only
–the intuitive thought stage (4-7yrs)–
-children are eager to learn a lot more
-centration: focus on one quality or feature of an object/something
-irreversibility: unable to understand that actions can be reversed
concrete operational stage
-decentration: viewing multiple viewpoints (opposite of egocentrism)
-seriation: the ability to sort objects into size/colour
-classification: can name objects according to appearance
-reversibility: can reverse actions
-conservation: understanding something stays the same in quantity even though its appearance changes
formal operational stage
-children develop the ability to think about abstract concepts
-they understand that time changes things
-aware of life has a sequence
-understanding that actions have consequences
what is schema?
mental representations of the world based on one’s own experiences.
what is morality?
general principles about what’s right and wrong
what is assimilation?
incorporating new experiences into existing schemas
e.g., a child sees a plane and calls it a bird
what is accommodation?
a schema no longer works and has to be changed in order to deal with the new experience
e.g., the child will see that birds are alive and planes are not., so they will have to change their ‘everything that flies is a bird’ schema
what is adaptation?
using assimilation and accommodation to make sense of the world.
what is equilibrium?
mental balance
Piaget and inhelder (1956): three mountains task
Aims?
-to see to what extent children of different ages could decentrate
Piaget and inhelder (1956): three mountains task
procedure?
-100 participants (4-12yrs)
-4 equipment used:
*wooden doll
*three mountains model
*10 pictures of the model from different angles
*3 coloured cards
-children were asked to use cardboard shaped to show how the mountain model looked from different viewpoints
-children were shown 10 different viewpoints and were asked to pick the picture that represented what they could see from different positions and what the doll could see
-children chose the picture and then positioned the doll so it could ‘see’ that veiwpoint
Piaget and inhelder (1956): three mountains task
results?
–pre-operational stage–
children of 4-6yrs chose pictures and places cardboard to show their own viewpoints. overall shows egocentrism.
–concrete operational stage–
7-9yrs children start understanding that others looking from a different position can see the model differently.
9-10yrs children can understand that the doll has a different view at different positions
qualitative data was collected
Piaget and inhelder (1956): three mountains task
conclusions
-children up to 7yrs old were egocentric
-towards the end of the pre-op stage children were more able to understand that there were different viewpoints
-older children were non-egocentric. they saw the mountains as objects relating to each other. they were able to position their own viewpoint among the views of others and could coordinate different perspectives
