Group Dynamics 



The ability of dedicated scientists to perform effectively as a team even 

 though they have individual scientific projects was an important experimental 

 variable. The formal relationships that were established and the informal 

 social groupings that developed during the missions could provide meaningful 

 habitat design and mission planning information. Reactions to stress due to 

 unscheduled activities and to living and working relationships, will provide 

 useful selection criteria data. 



Isolation and Confinement 



Although complete isolation from the "topside world" was not achieved, there 

 was a tendency for the aquanauts to respond to non-crew members as outsiders. 

 This was expected to occur and was studied to determine the extent to which 

 the TEKTITE crews depended on topside activities and to what extent they 

 resented topside involvement. The crews were confined to a small world 

 bounded by the habitat and the limited excursions in the area of the habitat 

 required for their marine sciences activities. 



Performance 



Scientific performance is always difficult to quantify. In this study immediate 

 performance criteria were substituted for ultimate criteria. Length of time 

 in the water shile involved in marine sciences, time spent in the analysis of 

 data, and preparation for following scientific efforts were all used as 

 immediate measures of performance. Time spent on routine duties and main- 

 tenance of self and habitat was measured. 



Psychomotor Tests 



Several psychomotor performance tests were planned for use in the 100 foot 

 missions in the Minitat primarily to provide sensitive measures of nitrogen 

 narcosis. Although these tests were used in the 100 foot simulator studies, 

 they were not used in the 50 foot missions. There were no 100 foot missions 

 using the minitat. 



Communication 



Communication could occur in a number of modes including open microphones, 

 private phone, standard radio systems and two-way video phone. The extent, 

 nature, and who initiated various types of communication was recordedo The 

 dependency of the aquanauts on the ability to communicate with topside was 

 observed. 



Stress Perturbations 



A critical area of study included stress caused by unprogrammed and unexpected 

 happenings. There were several earthquakes that rocked the area and one 

 potential hurricane that resulted in an aborted mission. The reactions of 

 the crew members to these and other unanticipated occurrences were recorded.
