Abstract
This paper investigates the use of area integration rules. 36 children in
Grades 4, 6 and 8 were given area judgement tasks, using rectangles of
varying areas and perimeters. Information Integration Theory
procedures revealed both additive and multiplicative judgement rules
that determined the children's responses. It was found that judgement
rules change intra-individually but there does not appear to be a
relation between judgement rule and Grade level. The form of
presentation of the rectangle was found to be important.
