abstract="The applicability of SAGAT method for measuring Situation Awareness in the driving context was analyzed in a driving simulator study. N = 20 subjects drove through a driving course with different specific demanding situations, in which they were asked for various aspects of the driving scene during the freezing of the simulation. In one experimental condition (n=4) the drivers additionally performed tasks in a hierarchical menu system during driving and answered questions about their system knowledge. SAGAT method showed strong test effects due to the repeated questions and a constraint to only explicitly reportable knowledge about the situation. No systematic correlation between SAGAT performance and driving performance could be shown. While driving with a secondary task there is a tendency in focussing the relevant aspects of the situation while neglecting the irrelevant ones and a decreased memory for further elapsed information. An adequate sequencing of the secondary task seems to have a positive effect on SAGAT performance. In contrast to previous approaches it is here proposed to rely more on behavioural parameters for measuring Situation Awareness. In the context of performing a secondary task while driving there is the assumption that Situation Awareness, defined as available knowledge about the situation and the required behavioural adjustment, influences the performance strategy of a secondary task. This demands an experimental design in which situation dependent decisions in the interaction with a secondary task can be used as a parameter for the Situation Awareness of the driver.  <p>Language: de.</p>  <p></p>",
