Measurement of Situation Awareness in Dynamic Systems

Endsley, Mica R.·1995·Human Factors: The Journal of the Human Factors and Ergonomics Society

Abstract

Methodologies for the empirical measurement of situation awareness are reviewed, including a discussion of the advantages and disadvantages of each method and the potential limitations of the measures from a theoretical and practical viewpoint. Two studies are presented that investigate questions of validity and intrusiveness regarding a query-based technique. This technique requires that a simulation of the operational tasks be momentarily interrupted in order to query operators on their situation awareness. The results of the two studies indicate that the query technique is not intrusive on normal subject behavior during the trial and does not suffer from limitations of human memory, which provides an indication of empirical validity. The results of other validity studies regarding the technique are discussed along with recommendations for its use in measuring situation awareness in varied settings.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Situation Awareness theory conceptualizes reasoning as a progression through three stages: Perception, Comprehension, and Projection.

    “Situation Awareness (SA) theory conceptualizes reasoning as a progression through three stages: Perception (noticing elements), Comprehension (interpreting their meaning), and Projection (anticipating consequences) [21, 22].”
  • Expert evaluators naturally distribute their work across Perception, Comprehension, and Projection, weaving together global and local reasoning and gradually moving from surface checks toward root-cause diagnosis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
