To determine if learned helplessness treatment debilitates human working memory and fluid intelligence, 60 university students, classified as high or low self-monitors, were assigned to one of three treatments: intermittent (50%) controllable positive feedback, uncontrollable (yoked) negative feedback, and no treatment. Test tasks included backward digit and backward spatial span (representing working memory), matrices (representing fluid intelligence), vocabulary (representing crystallized intelligence), and forward digit and forward spatial span (representing immediate span of apprehension). Results generally were not significant and were discussed as possibly due to ineffective treatment procedure. Further research on this topic is needed.

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
