Given that HMDs are projected to be adopted into emergency response work, questions are raised about the effects of HMD use during climbing or other physical tasks.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method:<\/jats:title>\n                    <jats:p>Climbers performed five conditions\u2014a climbing-only condition, two dual-task climbing conditions (words presented on the HMD with and without auditory warnings while climbing), and two seated control conditions (words presented on the HMD with and without auditory warnings)\u2014in a repeated-measures design.

Participants slowed around word presentations on the HMD. Additional comparisons to previous research indicate that physical tasks may be more detrimental to word recall than are seated tasks and that visual stimuli might hinder climbing performance more than do audible stimuli.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Complex physical activity, like climbing, is disruptive to memory rehearsal and later recall, and cognitive tasks disrupt physical performance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Application:<\/jats:title>\n                    <jats:p>Avoiding cognitive HMD tasks requiring later recall during complex physical activity is advisable.
