- Samuel & Bryant
- Aim
- To test one question against Piaget's two-question method on a variety of conservation tasks, on several age groups.
- Background
- Piaget stages of development.
- Rose & Blank
- Procedure
- Lab experiment & repeated measures. IV - age of child, task given or condition. DV - whether the child shows conservation(no. of errors made).
- Mass - 2 equal balls of play-doh were shown, one squashed & children had to compare.
- Volume - 2 equal glasses of water were shown to the child, one poured into a different shaped glass & children had to compare.
- Number - 2 equal rows of counters were shown to the child, one stretched out & the children had to compare.
- Participants
- 252 children aged between 5 and 8.5 years from playgroups/schools in Devon.
- Split into 4 groups, 63 in each group. (5yrs 3months, 6yrs 3 months, 7yrs 3 months and 8yrs 3 months.)
- Each subgroup of 21 was given a different condition - children had 4 trials of each task.
- Results
- The younger children made more errors on all of the tasks.
- The children all did better in the one question condition, and worst in the fixed array.
- The children found it hardest to understand change in volume.
- Conclusions
- Young children can conserve earlier than Piaget suggested. But they do learn to conserve with age.
- Conservation skills vary across tasks, Number before volume and mass.
- Evaluation
- It was a complex study as it had 3 IV's, development on Rose & Blank.
- Large sample so is representative but could be ethnocentrically biased.
- Quantitative data was collected - easy to analyse.
- Children could've been distressed when waiting to be tested on. They also didn't give their consent.
- Aim
