252 HUMAN BEHAVIOR PROGRAM 



Topside Audiovisual Monitoring During Submersion 



This program consisted mainly of recording behavior in the habitat observed on TV or 

 sounds heard over the open microphones in Sealab. Television and audio signals were moni- 

 tored 24 hours a day for the entire study. These data included: 



1. Order of arising — Observation of when and in what order men got up. 



2. Meal recording — Record of who prepared each meal, when each man ate, and who 

 cleaned up. Attempts were made to judge mood and activity during meals. 



3. Location record — Taken every half hour. A record of where each man was and what 

 he appeared to be doing if on camera. Activity and mood were also rated. 



4. Activity record — A frequency count of the number of times each man moved on and off 

 one of the cameras. Recorded for one-half hour eight times per day. 



5. Laugh record — A frequency count of laughs heard over one open microphone set at a 

 standard level during a half -hour period. Recorded four times per day on Teams 2 and 3. 



6. Night watch record — A recording made every 15 minutes from 2000 to 0700 hours indi- 

 cating who was up and what they were doing. Other measures were suspended during this time. 



7. Log book — A running account of "significant" occurrences observed over TV or audio 

 signals, or learned of in other ways. 



8. Telephone calls — A count of the number of calls made by each man each day. 



Postdive Data 



Following each 15-day submersion, the divers underwent approximately 30 hours of de- 

 compression. This was followed by about a six-hour rest period and a press conference of 

 1-1/2 to 2 hours. The debriefing period began at 1300 on the second day, about 50 hours after 

 leaving Sealab. Three men were debriefed the first afternoon, three more the following morn- 

 ing, and the remaining three or four men the second afternoon. The debriefing consisted of an 

 audiometric examination, medical examinations, the completion of questionnaires, and a per- 

 sonal interview. 



The members of the Human Behavior Program had the responsibility for the following: 



1. A debrief interview of each diver. 



2. A debrief questionnaire filled out by each diver. 



3. Sociometric questions — Choices of most preferred leaders and teammates. 



4. Audiometric tests — Examinations were given to each diver at times ranging from 12 

 hours to 36 hours after they emerged from the decompression chamber. These tests were ad- 

 ministered by the same individual, using the same equipment as for the predive test. Although 

 it is recognized that there may possibly have been temporary threshold shifts immediately 

 after coming out of the water, circumstances did not permit earlier examination. 



In addition to this program, data have been gathered from numerous log books of both an 

 official and personal nature. Much of this data has not been analyzed at the writing of this 

 report. A detailed analysis of such information should greatly increase our understanding of 

 life and work in Sealab.
