An Example of Causal and Spatial Functionsle to study in this respect a causal situation in which the variables are relatively easy to distinguish and to analyze both separately and together. A transitive movement resulting from a single thrust linked to an action, whether direct or instrumental, is certainly the most primitive example from

The Composition of Differences: Unequal Partitionsbserving that the inductive discovery of the underlying law is possible from about age 7. It might now be interesting to examine a somewhat more complex function which would encompass the previously studied one. In other words, we will study the operatory composition of functions. The following task

The Relation Between the Size of a Wheel and the Distance Travelled vary in the same direction, i.e. the larger the wheel, the greater the distance travelled, and vice versa. As a concrete example, we roll a wheel, the distance travelled being the result of this rotation. While the child can effectively observe the dimension of ‘distance’, how is he able to isolate

The Inverse Proportional Relationship Between Weight , and Distance , (Arm of a Lever) in the Equiliciprocal compensation of the sizes involved in ., the establishment of an inverse proportionality. Our purpose was not to make the problem more difficult to solve but to understand how the child is able to establish a functional law by experimental induction. Given a balance arm in equilibrium with
