and Kleerekoper 1970), considerable systematization of various locomotor 

 variables could be demonstrated, but recognition of the exact nature of the 

 resulting system awaited detailed time-series analysis of existing and new 

 data. 



This was carried out under the direction of Dr. J. H. Matis, of the Institute 

 of Statistics of Texas A & M University. These studies firmly established, and 

 quantified to a considerable degree, the principle that locomotor behavior is 

 determined in magnitude as well as occurrence over time, by a highly orga- 

 nized interdependence of locomotor variables (Matis et al. 1973; Matis, 

 Childers, and Kleerekoper 1974; Matis, Kleerekoper, and Gensler 1974). 

 The new insight made possible quantitative analysis of exploratory behavior
