[Effect of transmeridional flights and mountainous conditions on different kinds of memory]

The effect of transmeridional flights and highland exposures on memory processes was studied. During 21-day observation following an environmental change memory processes were activated: short-term memory storage increased, proceptive and retroactive interference decreased, fixation of memory track improved, number of reminiscences grew, and forgetfulness lessened. These processes were especially active during 11th though 21st days of adaptation. Improvement of short-term memory was found in verbal and nonverbal tests, nonverbal short-term memory being changed more significantly. These findings point to the leading role of memory in the development of adaptive behavioral programs. The conclusions can be applied to the selection of optimal mental tasks given to the man after his transmeridional flight or transfer to highlands.
