1. To see if children under 7 could understand conservation

   • built on work of Rose and Blank who modified Piagets original work by only asking children one question after the transformation had taken place
     • Done to avoid confusion
     • only tested 6 year olds

2. used children aged 5, 6, 7 and 8

   • 252 from devon
     • four groups of 63 by age
       • divided into 3 groups of 21

3. standard condition- two questions

   • one judgement condition- 1 question post transformation
     • fixed array condition- shown pre and post transformation displays together and asked if they had the same

4. each child took part in 12 trials 4 each for number, mass and volume

5. Lab experiment with an independent measures design

6. IVs- age, experimental condition, different conservation tasks

7. 5 yr old children mean number of errors -standard 8 - one judgement 7 -fixed array 9

8. 6 yr/0 children -SC6 -OJ4 -FA9

9. 7yr/o 3, 3, 5

10. 8yr/o 2, 1, 3

11. older children made fewer errors and children who saw the transformation and were only asked one question made fewer errors
