Cognitive processing strategies can explain general word-formation preferences that influence the structures and their developments. They are based on simplicity, transparency, iconicity, salience, and frequency. We present and discuss evidence from our data on first language acquisition for how these cognitively based general preferences can explain the course of development of word formation and how they interact or compete. The analysis is based on the development of distributions of word formations in longitudinal data and panel data of child speech and their input from high and low socio-economic status families. In order to evaluate the productivity of a word-formation pattern in child speech, we applied the mini-paradigm criterion. Age-of-acquisition effects will be presented according to our own processing studies and to literature.
