tending toward depression and anxiety rated the habitat as having less variety 

 (r = .36 and .37, respectively). All of the above correlations are statistically 

 significant (> .01 percent). It appears from these results that one's moods or 

 morale in an isolated habitat are highly interrelated with one's attitudes 

 toward the habitat and support from topside, and with one's actual worl< and 

 leisure tendencies while in the habitat. It Is not yet possible to state 

 whether attitudes about the habitat influence moods or vice-versa. 



Personal i tv Data 



Personality data showed, for example, that the scientist aquanauts were unusually 

 reserved, intelligent, emotionally stable, and imaginative as compared to the 

 normal population. The engineers differed from the normal by being unusually 

 intelligent. Male and female aquanauts were similar on all factors except con- 

 scientiousness, the females being somewhat more conscientious. 



Relationships between personality scores on the I6PF and mood responses were 

 not of sufficient strength to be used as a basis of crew selection and are not 

 of major theoretical importance. Further details can be obtained by writing 

 the authors. 



Two personality t ra i ts-- intel 1 i gence and suspi ciousness--were found to be 

 strongly predictive of habitat adjustment: intelligence correlates with direct 

 marine science (r = .57), total leisure (_r - -.53), solitary recreation (r = -.52), 

 total marine science (r = .51), total work (_r = .•48), total in-water diving 

 (r = .39), marine science support (r = .36), idling (r = -.36), and sleeping 

 (^=-32). 



Suspiciousness correlates with direct marine science (_r = -.42), total in-water 

 diving (_r = -.40), total leisure (_r = .39), and solitary recreation (_r = .34). 

 In summary, more intelligent, less suspicious crewmen tend to adapt better to 



the habitat. 



Postdive Debriefing 



The debriefing interviews were examined from several aspects, and part of the 

 interview data is presented subsequently under leisure time. Aquanaut complaints 

 made during their interviews are discussed below. Complaint was broadly defined 

 to include any criticism or problem that the aquanaut reported with respect to 

 his stay in the habitat. A total of 859 such complaints were counted in the 

 interviews, which is an average of 17.9 per aquanaut. These are classified under 

 broad headings as shown in Figure 2. Most complaints centered around the general 

 area of habitat design. Specifically, the aquanauts were dissatisfied with the 

 design of the habitat affecting the performance of their tasks. A somewhat 

 different picture appears in the interview data than the HARS and TEA data 

 because the aquanauts can highlight their criticisms more freely in the interview. 

 Thus, although the access to news was roundly condemned on the HARS, this issue 

 was not nearly as great during the aquanauts' interviews as was the general 

 issue of task support. Also, there is a fairly large area of locomotion support 

 or mobility about which there were numerous complaints; this was overlooked in 

 designing the HARS format.
