Belief revisions in the cognitive development of proportional reasoning: dynamics, statistical models and computational models

چکیده
In the balance scale task, children are asked to predict the movement of a balance scale. Equally heavy weights can be placed on the arms of the scale, at equally spaced distances. Figure 1 shows a graphical display of a balance scale problem. Blocks underneath the arms prevent the scale from tipping. The task assesses proportional reasoning as it requires the understanding of the multiplicative relation between the dimensions.

متن کاملRule transition on the balance scale task: a case study in belief change
For various domains in proportional reasoning cognitive development is characterized as a progression through a series of increasingly complex rules. Amultiplicative relationship between two task features, such as weight and distance information of blocks placed at both sides of the fulcrum of a balance scale, appears difficult to discover. During development, children change their beliefs abou...
