1979
This paper aims to present an analysis of the concept of mental load from the point of view of human performance theory. In the first section the theoretical status of the concept of mental load is considered. It is concluded that it is based upon common sense, which cannot be supposed to be empirically founded in a simple way. Then an outline is given

Sinusarrhythmia and Mental Work Load
1979Sinusarrhythmia is a variability in heart rate and this variability has been associated with respiration. In the last decade however, an increasing insight into the mechanisms underlying this phenomenon has been obtained, mainly by research effort of British investigators (Sayers, 1973, 1975; Kitney, 1972, 1974; Hyndman, 1974, 1975, 1976; see also ...

Mental Load in Monitoring Tasks
1979In this paragraph I will briefly give the background of the Aviation Safety Research Office at NASA Ames to provide the viewpoint from which I will make the comments that follow. The ASRO has been set up to define operating problems in today’s aviation system and to suggest solutions that can be implemented in a relatively short time; a typical time ...

Sinus Arrhythmia as a Measure of Mental Load
Ergonomics, 1974This experiment examines the proposition that sinus arrhythmia is a measure of mental load. The experiment involved a subtraction task in which the physical and mental loads could be varied independently. The results indicate that sinus arrhythmia does decrease with on increase in mental load.

Evaluation in a down-loaded mental health system
Evaluation and Program Planning, 1986Speculation that policy and funding shifts in the nation's mental health system would negatively impact program evaluation services in community mental health centers (CMHC) is substantiated. Performance of program evaluation activities was investigated in 71 CMHCs in 15 states over a two-year period.
