Task execution times for all task complexities and task execution
types are statistically significantly shorter for Elastic Windows at
the 0.05 level, except for sequential scan and recall context +
scan in the low complexity treatment. Table 
shows detailed statistical results for each task execution at all task
environment complexities.
The mean task execution times for all types increased dramatically for
the independent overlapping windows treatment. Such as for comparison
mean times are 
and
. However, the increase in the mean task
execution times is slower. Figure shows the mean
task completion times with standard deviations and minimum and maximum
times.
