The Developmental Approach: Samuel and Bryant

Based on Piager and the theory of Cognative Development in children. By using Conservation tasks of Mass, Number and Volume. Piager always used 2 Questions both before and after the transformations. He found that children passed the tasks at the ages of 7-8 years as they entered the concrete operational stage of development. 

 Aims:

- To test conservation ability in children aged 5 to 8 years and to see wether having a pre and post transformation question was an influencing factor on the responses given. 

IV:

- One question Format- 3 conditions; 2 questions, 1 question and fixed array 

- Age of child- 4 groups; 5, 6, 7 or 8 years old

- Materials used- 3 forms; Mass, Number and Volume

DV:

-Number of errors on each conservation task

Controls:

-All participants aged between 5 and 8 years

-Same tasks used

-Repeated tasks 12 times per participant

-Same questions asked 

-Each task perfromed 4 times by each participant 

-Each child only has 1 question type 

Sample:

252 children 

-63 aged: 5years 3 months   

-63 aged: 6years 3 months

-63 aged: 7years 3 months 

-63 aged: 8years 3…
