A dissertation submitted to the Faculty of Arts,
University of the Witwatersrand, Johannesburg,
for the Degree of Master of Arts. / Increasingly complex technology in modern times has changed the nature
of many work activities. Mechanisation and automation have served to
emphasise the importance of mental workload to productivity, physicaI and
mental health. The study uses a simulated routine office stocktaking task
to compare subjective experiences of mental workload between traditional
pen and paper methods and the more recently developed computer techniques.
An analysis is also made of assessments of difficulty by subjects free
to adopt a working method of their choice (ie. in a flexible environment)
and subjects whohave no freedom of working method (ie. a rigid externally
imposed working strategy). Also included is an analysis of the cognitive
strategies adopted during task performance and across the different
t.reatmerrt conditions. Research findings are of particular relevance to
the design of jobs in the modern office environment where human-computer
interaction is becoming increasingly prevalent, the effective design of
man-machine systems, and to the general field of workload research. / AC2018
