Electronic monitoring systems are becoming a prominent feature of the
modern office. The aims of the present study were three-fold. First, t
o assess the effects electronic security monitoring systems (ESM) have
on the user's physiological state. Second, the researches aimed to ex
amine the effects explicit security challenges have on both user behav
iour and physiological state when using an ESM system. Finally, the re
search aimed to examine the effects one form of electronic performance
monitoring system may have on the user's physiological state. To this
effect, the present study examined the physiological and performance
effects of two simulated electronic monitoring systems (security/perfo
rmance). The computer task required 32 subjects to enter mock clinical
case notes under various conditions. In the first session subjects we
re only required to enter the case notes while keystroke data were col
lected. The second session was divided into three discrete stages. In
the ''security baseline'' condition, subjects were informed that a key
stroke security monitoring system had been instituted, bu: no security
challenges occurred. In the ''security challenge'' condition, however
, a number of explicit security challenges occurred. In the final ''pe
rformance monitoring'' condition, subjects were informed that their da
ta entry speed was monitored and they were placed on a response-cost s
chedule for poor performance. Blood pressure and continuous inter-hear
tbeat latency were recorded for the security and performance condition
s. Results indicated that monitoring systems have the potential to evo
ke altered arousal states in the form of increased heart rate and bloo
d pressure. Contrary to expectations, the hypothesized improvement in
task performance within the performance monitoring condition was not o
bserved. The implications of these results for the design and implemen
tation of electronically based behavioural-based security and performa
nce monitoring systems are discussed. (C) 1998 Academic Press Limited.
