- Other explanations
- Natavist / knowledge of the physical world
- we are born with innate cog structures which determine cognitive ability
- development relects this genetic predisposition
- Bower
- infants aged 6-21 days attempt to move their heads away from an object moving towards them
- this shows that babies can percieve depth at a few days old
- Nature provides us with this ability
- piaget underestimates the infants understanding of the real world
- infants aged 6-21 days attempt to move their heads away from an object moving towards them
- Baillargeon
- challenged object permenance at 8 months
- 3 month babies placed infront of a screen, tall and short carrotts
- babies looked longer at the tall carrot which means they show more interest and therefore have object permenance
- aware of continued existence
- Evaluation
- artificial, implies looking at the object for longer relects interest when there may have been other reasons
- although the children show sophisticated understanding of object permenance they are not as able when tested on other aspects such as gravity
- The information processing
- Humans processing is similar to that of a computer
- focus on cognitive processes
- perception
- attention
- memory
- problem solving
- similar to piaget in that it specifies key changes in information as the child develops
- different to paiget in that the changes relect quantitively leading to increased cognitive efficiency
- bee
- 4 changes with age
- increased processing capacity
- increased processing efficiency
- development of rules for problem solving
- development of metacognition
- 4 changes with age
- sieglar
- used a balance weight problem to test whether children approach tasks differently according to age
- Most weights or furthest from middle or guess or mathmatic equation
- found processing strategies became more complex with age
- Evaluation
- new teaching techniques - reflecting on mental processing
- use of computer means social and emotional factors are ignored
- separate components have been analysed in detail so it is clear how it affects them
- Natavist / knowledge of the physical world
