COLUMN IEQ APPLICATIONS

knowledge workers typically complete a variety of non-standardized
work tasks, the current best practice
is to collect subjective measures
of productivity: workers are asked
to estimate their productivity or
the effect of the environment on
productivity.5 While subjective
measures may not be as rigorous as
objective measures, they still allow
for the effect of the environment on
productivity to be quantified.
Underlying people's performance
across different tasks is cognitive
performance. Cognitive performance encompasses basic and
higher-order cognitive functions
such as perception, attention, association, pattern recognition, reasoning, memory, decision making, language use, judgment and decision
making and thinking and reasoning.
Given the vast array of cognitive
functions and available measures of
each, we suggest starting by measuring the domain-general cognitive
functions that are important across
a variety of tasks: executive functions. Executive functions are the
top-down cognitive processes that
allow us to form goals, plan and
execute goal-directed behaviors.6
The name "executive" is a metaphor
for the CEO or supervisory system of
our mind that controls and regulates
more basic cognitive processes, such
as perception. Executive functions
are important throughout the lifespan: for school performance, work
success, risk of marriage and family
conflict, ability to maintain independence in older adulthood, as
well as health and quality of life.6

Measuring Human Performance
At least three executive functions
are related but separable from one
