Abstract

Connectionist simulations of children's acquisition of velocity (v), 
time (t), and distance (d) concepts were conducted using a 
generative algorithm, cascade-correlation (Fahlman & Lebiere, 
1990). Diagnosis of network rules were consistent with the 
developmental course of childrens concepts (Wilkening, 1981, 1982) 
and predicted some new stages as well. Networks integrated the 
defining dimensions of the concepts first by identity rules (e.g., v = 
d), then additive rules (e.g., v = d-t), and finally multiplicative 
rules (e.g., v = d/t). Psychological effects of differential memory 
demands were also simulated. It is argued that cascade-correlation 
implements an explicit mechanism of developmental change 
involving incremental learning and qualitative increases in 
representational power. 

The paper has been published in the 1994 Proceedings of the 
Sixteenth Annual Conference of the Cognitive Science Society (pp. 
72-77). Hillsdale, NJ: Lawrence Erlbaum.
