at the University of Texas who were trained in systematic observational 

 techniques. They were also qualified divers who provided logistic diving sup- 

 port for each aquanaut team. This common interest in diving and aquanaut 

 support served to build rapport between the psychological mission and the 

 aquanauts. 



The variables on which data were collected were developed and defined from 

 research programs conducted during SEALAB II and III and TEKTITE I (see Radloff 

 and Helmreich, 1968, and Radloff, 1969, for further exposition of the research 

 design). The final definition of variables was determined by the authors in 

 conjunction with Richard S. Mach of Bellcomm, Inc. and Roland Radloff of the 

 Naval Medical Research Institute.
