Zusammenfassung
The dominant technological trajectory in vehicle design brings with
it similarly dominant driver performance issues in regard to vehicle
feedback and driver situational awareness (SA). Three experiments
are reported in this paper that describe not only the effects on
driver SA of manipulations of vehicle feedback but also illuminate
issues concerned with SA measurement methods and contexts. The findings
suggest that current trends in vehicle design may contribute little
towards a driver’s SA and, in fact, may actually show a generalized
trend towards decreasing it. The efficacy of verbal protocol and
probe recall SA measurement techniques is noted in terms of observing
this effect. On the other hand, a concerning dissociation occurred
with findings from a self-report measure of SA. Drivers appear to
show a concerning lack of self-awareness of their SA and, indeed,
any shortfall in it
