A study of area conservation using a simple method of adjustment

The method of adjustment was adapted to study conservation of area with Papua New Guinea High School students. Subjects were shown a standard field, representing “a block of land”, with a “house” in each corner. An identical comparison field. with adjustable borders was presented under one of two conditions. In one condition the houses were placed along one side, and in the other they were placed randomly about the field. Non‐conservers were invited to adjust the borders of the comparison field to match the area of the standard. Non‐conservers in the Edge condition reduced, and those in the Random condition increased, the size of the comparison field.
