This study describes an experimental investigation where cardiovascular response was measured for a range of stimuli. The aim was to obtain relationships between stimuli and physiological variables that could be implemented in a general control system where the appropriate stimulus is selected for a desired test. Reaction time (Tr), blood pressure (BP) and heart rate (HR) were measured in 14 first-year aviation students (10 males, 4 females, age 19-23 years) during different types of computer-based tests : visual, auditory, mathematical. For all test responses across all subjects mean BP increased in 95%, HR increased in 66%. Both BP and HR increased concomitantly in 61% of responses. Average Tr was 583msec (visual), 477msec (auditory) and 10.3 sec (math). There was also a positive relation between BP, HR and Tr. A difference in these parameters was also seen between males and females. Findings of this study show that response to stress results in increased BP but not HR for all subjects studied. This indicates that short-term regulatory mechanisms of BP and HR are manifest only in some subjects some of the time for similar stimuli. These results can be used to implement an assessment procedures and test response criteria in an automated system for testing young student pilots.
