Abstract:

Research in psychological changes associated with hyperbaric pressure - particularly the behavior changes identified as nitrogen narcosis - has yielded varying and often inconsistent results. One phenomenon reported frequently in nitrogen narcosis is an acclimatization or adaptation to the conditions of the dive thus, experienced divers are found to be less effected by narcosis. Precise quantification and identification of the behaviors and the environmental conditions under which they occur has been lacking in most hyperbaric studies dealing with adaptation to narcosis. The present study is a preliminary one dealing with an experimental analysis of time behavior, using operant conditioning techniques. Timing behavior in albino rats if sound to be disrupted in an initial exposure to 200 feet on air. Subsequent exposures reveal gradual adaptation to the chamber conditions, with return to levels of performance close to surface control. Author
