The significance of psychophysiological markers for the accelerated aging of short-term memory is assessed by comparative analysis of two occupational groups in order to determine the relative impact of job specifics on the state of mental working capacity. The specific features of the systemic structure of functions determining mental working capacity that depend on the age and length of employment in the surveyed groups are identified. It is shown that mnemonic functions are subject with increasing age and length of employment to quantitative and qualitative changes that are expressed in a reduction in the amount of memorized material, a slowed memorization process, and a reinforced downward trend of memorization accuracy. It has been established that premature age-related changes in the values of psychophysiological indicators among truck drivers are “risk indicators,” and long driving experience is a real risk factor accelerating the aging process.
