Abstract

Temporal stability and transsituational consistency are important characteristics of cardiovascular responses to mental or static load. While in the literature stability is generally estimated as the relationship between only two test sessions, it is unknown whether these stability estimates can begeneralized across multiple replications of the test situations. Forty subjects (20 males and 20 females) were tested four limes with intervals of 1 day, 1 week, and I month. Each test session comprised two mental tasks (mental arithmetic and colour-word test) and a static (fingergrip) task. The physiological variables recorded were heart rate, systolic blood pressure, and diastolic blood pressure. The adaptation processes in the course of the four test sessions are more pronounced for the mental tests than for the static test. The temporal stability, restricted to test sessions 1 and 2, can be used to estimate the general stability across all pairs of test sessions. However, there are some non-systematic differences which indicate that more than two test sessions yield more reliable results. Averaging across twotest sessions, compared with the stability of single test sessions, increases the stability of heart rate reactivity from 0.60 to 0.73. Low correlations between the responses to mental and static load indicate that there aredifferent underlying regulatory mechanisms. The results show that the responsivity can be assessed more reliably when more than two tests are performed. The responses to one type of stressors (mental or static) cannot be generalized to an overall responsitivity. Copyright (C) 2001 John Wiley & Sons, Ltd.
