The current study investigated the relationship between a measure of trait
boredom, Boredom Proneness, and vigilance performance on a variation of Mac
kworth's original clock test. Performance, assessed as Sensory Efficiency,
was negatively correlated with Boredom Proneness scores early in the vigil
but not during later trials. The results suggested that the trait of Boredo
m Proneness is predictive of performance on monotonous tasks within the fir
st 10-min. block of trials; however, no differences in performance occurred
on subsequent blocks, suggesting that as state boredom increases, differen
ces between individuals diminish, e.g., a ceding effect. The authors discus
s the importance of examining Boredom Proneness as a multidimensional const
ruct. Practical implications for these results are presented, particularly
in terms of using Sensory Efficiency as a measure of performance during vig
ilance tasks.
