The study demonstrates the use of the expanded TLX instrument (Helton, Funke &
Knott, 2014) for cognitive and team-related workload self-assessment of 38 participants, solving the UNISDR – ONU stop disasters game simulation. Subjectsin one group (GF; n=30) performed group decision-making without prior individual practice on the simulation. A subset of GF participants (n=6) subsequently reiterated the simulation alone, reassessing their cognitive workload. Another group (IF; n=8) individually performed the simulation and reiterated it in groups. Most GFparticipants, moving from group to singly conditions, reported decreasing physicaland temporal demands, unchanged self-assessed performance, and increased mentaldemands, effort and frustration. IF participants incurred...
