Article
It has been suggested that complexity in fault diagnosis tasks is largely a function of problem complexity and little to do with the perceptual complexity of the format in which the system representation is displayed. An experimental study is reported which shows that a left-to-right diagonal display format improves the speed and diagnostic efficie...
Article
The selection of test points when fault finding with a hierarchically paged display is more efficient than when using a scrolling display. However, this difference is not found with more able subjects. An unexpected finding is that both displays seem to facilitate more consistent performance than that obtained when the operator's view of the system...

Article
Two experimental studies are described of the effect on performance of alternative program representations in different components of program debugging tasks. The use of diagrammatic notation provides useful information when the debugging task is mainly concerned with tracing execution flow in a program. In more complex tasks involving the identifi...

Usability does not exist in any absolute sense; it can only be defined with reference to particular contexts. This, in turn, means that there are no absolute measures of usability, since, if the usability of an artefact is defined by the context in which that artefact is used, measures of usability must of necessity be defined by that context too....
Chapter
We are only just beginning to come to terms with the fact that users of computer systems are individuals, and that they may wish to do their jobs in ways that don’t quite fit with the collections of functional services and user interface styles known as “applications” dreamt up by software developers. The potential of Computer Supported Cooperative...
Chapter
Relatively little is known about the extent or nature of doctors’ uncertainty in clinical practice. While clinical decision making has been studied extensively by workers such as Elstein [Elstein et al 1978], Gale and Marsden [1985] and Johnson [Johnson 1982; Johnson et al. 1983], none of these studies shed much light on the question of when, or ho...
Chapter
Decision-making in general practice is not a simple matter of a patient presenting a problem and the doctor making a rational, correct decision. The human skills of decision-making are often poor, although at the moment still better than automated decision-making, especially where the problem is ill-defined.
Chapter
The function of man in man-machine systems is increasingly that of problem-solver. The role of fault-finder is a case in point. The extent to which training can provide problem-solving skill remains a comparatively neglected topic. Nor should one neglect the classical question of how the problem is represented in the first place. The performance di...
Article
The effects were studied of two types of training of fault-location performance in networks of interconnected logic units. The types of training were (i) computer aiding which provided information about the efficiency of tests and diagnoses not warranted by available indications, and (ii) pre-training in strategies appropriate to different network...
Article
Experimental studies of fault-finding performance typically take place over a limited number of sessions. This paper reports a study of extended practice of fault location in networks of logic units. Perfect performance was never achieved by subjects participating in the experiment. Error rates on some measures of diagnostic efficiency increased ov...

Chapter
The computer is firmly embedded in the fabric of our industrial and commercial life, and it seems likely that our dependence on information processing technology will increase in the new decade. However, there is a widening gap both in cost and in sophistication between the hardware and the software of the computer systems. We find only too often t...
Article
Full-text available
Cyclic error curves are often found when people judge or set the position of a marker on a linear scale, but various different forms of cyclic pattern have been reported. Twelve subjects each made judgments and also made settings, both on a horizontal linear scale and on a vertical one. Analysis of their error patterns showed a strong tendency to g...
Article
Two experiments are described which investigate the effects of providing information about the diagnostic process during training in fault diagnosis. This process information is presented by an interactive computer program. The experimental results demonstrate that some generalizable strategic learning takes place. This learning is apparently depen...
Article
Experimental studies of the flowchart as an aid to debugging programmes or other procedural descriptions have provided ambiguous results. An experiment which removes some of the procedural problems of earlier studies is reported. It is concluded that the presentation of procedural information in the form of a flowchart has no effect of increasing t...
Article
A training program is described which provides, during fault diagnosis, additional information about the relationship between the remaining faults and the available indicators. Since this information changes throughout the process of fault diagnosis, an interactive computer system seems to be the most suitable training implementation. The computer...
Article
Sinusoidal constant error curves frequently occur in the judgment of nurnerical proportions, but there are puzzling discrepancies Sinusoidal constant error curves frequently occur in the judgment of nurnerical proportions, but there are puzzling discrepancies in the direction of constant error reported in various experiments. An experiment showed t...
