Development of the Concept of Proportionality from Early Childhood to Adulthood: The Importance of Context.
McWhirter, Elizabeth P.
Interpretation of experimental tasks is influenced by knowledge of the language used, by assessment of what the experimenter intends, and by how subjects themselves would normally represent the physical situation. Whether these processes in which children engage in cognitive studies differ from those employed by adults in similar tasks was investigated through a number of experiments which used different response criteria and different procedures. Focusing on proportional judgements of weight, area and volume the experiments demonstrated that when young children are given "sensible" tasks, they will perform better than expected. However, mature interpretation and performance by adults could not be taken for granted. In tasks derived from mathematics, science or logic, results suggested that cognitive processes might be increasingly hindered with age by interference from related but more familiar and more functional concepts, and from inappropriate experiential-rules from life.
