Abstract
We used cascade-correlation to model human cognitive development 
on a well studied psychological task, the balance scale. In balance 
scale experiments, the child is asked to predict the outcome of 
placing certain numbers of equal weights at various distances to the 
left or right of a fulcrum. Both stage progressions and information 
salience effects have been found with children on this task. 
Cascade-correlation is a generative connectionist algorithm that 
constructs its own network topology as it learns. Cascade-
correlation networks provided better fits to these human data than 
did previous models, whether rule-based or connectionist. The 
network model was used to generate a variety of novel predictions 
for psychological research.

Keywords: cognitive development, balance scale, connectionist 
learning, cascade-correlation
