Abstract:Metaphor graphics are data displays designed to look like corresponding variables in the real world, but in a non-literal sense of “look like”. Evaluation of the impact of these graphics on human problem solving has twice been carried out, but with conflicting results. The present experiment attempted to clarify the discrepancies between these findings by using a complex task in which expert subjects interpreted respiratory data. The metaphor graphic display led to interpretations twice as fast as a tabular (flowsheet) format, suggesting that conflict between earlier studies is due either to differences in training or to differences in goodness of metaphor, Findings to date indicate that metaphor graphics work with complex as well as simple data sets, pattern detection as well as single number reporting tasks, and with expert as well as novice subjects.

Digitalized nuclear instruments and control systems have become the main stream design for the main control room (MCR) of advanced nuclear power plants (NPPs) nowadays. Digital human-system interface (HSI) could improve human performance and, on the other hand, could reduce operators’ situation awareness as well. It might cause humans making wrong decision during an emergency unintentionally. Besides, digital HSI relies on computers to integrate system information automatically instead of human operation. It has changed the operator’s role from mainly relating operational activity to mainly relating monitoring. However, if operators omit or misjudge the information on the video display units or wide display panel, the error of omission and error of commission may occur. Therefore, how to avoid and prevent human errors has become a very imperative and important issue in the nuclear safety field. This study applies Performance Evaluation Matrix to explore the potential human errors problems of the MCR. The results show that the potential problems which would probably affect to the human performance of the MCR in advanced NPPs are multiple accidents, pressure level, number of operators, and other factors such as working environmental.

Listed are 90 reports of the Performance Evaluation Tests for Environmental Research (PETER) Program. Conducted from 1977 to 1982, the programs' purpose was to develop a test battery for use in repeated measures investigations of environmental effects on human performance, e.g., vehicle motion, toxic substances, aging, etc. The battery also has applications to training, selection, and research on equipment design. The PETER Program concentrated on selecting tests which remained stable with repeated measurements, as environmental research usually involves testing before, during, and after exposure. Stability of the means, variances, and intertrial correlations ensures that simple analyses may be applied with minimal complications and without difficulties of attribution of effect. Over 80 measures were evaluated, 30% were found suitable for repeated measures applications, 20% were acceptable for limited use, and 50% could not be recommended. The unsuitability of many tasks brings into question the validity of portions of the literature on environmental effects. The reports describe program rationale, development of statistical methodology, and stable tasks. PETER reports are available from published sources, authors, or the Naval Biodynamics Laboratory.
