piaget's (1952) study into the conservation of number Flashcards
sample
Swiss children in the pre-
operational & concrete
operational stages.
aim
To see the stage of development when children are able to conserve.
research method
Natural experiment and cross-sectional study
procedure
a) Each child was presented with two
identical, parallel lines of counter.
b) Was asked “Is there the same number of
counters in each row?”
c) Then watched as one of the lines was
spread out (no more counters were added).
d) Was then asked for 2nd time “Is there
the same number of counters in each row?”
findings
Children at the beginning of the pre-operational
stage (3-4 years)= more in stretched row.
Children at the end of the pre-operational stage
(5-6 years)= both the same, couldn’t say why.
Children in the concrete operational stage (7+)
= both rows the same & could explain why.
conclusion
Children in the concrete operational
stage were able to conserve.
limitations
Sample too small & culturally biased
(Swiss, own children)- cannot be
generalised.
Design is invalid- asked same qu.
twice so some answered based
thinking it was wrong the 1st time.
