Assessed via use of the six bipolar scales of the SURG-TLX , we found differences in task workload between the hot and cold conditions in the areas of physical demands ( hot @ -LSB- @-@ -RSB- , cold @ -LSB- @-@ -RSB- , P = @ ) and distractions ( hot @ -LSB- @-@ @ -RSB- , cold @ -LSB- @-@ @ -RSB- , P = @ ) .
