Summary

The Situational Awareness Rating Technique (SART) is a subjective, multi-dimensional rating method for estimating situation awareness (SA), developed by Taylor (1990) for aircrew systems design. Where human-engineering activity in aircrew system design had traditionally concentrated on operator workload, SART extends subjective estimation to SA so that it can be quantified and used to validate crew-systems-integration design objectives. It is the SA counterpart to NASA-TLX for workload, and complements the theoretical SA model in Situation Awareness with a measurement instrument.

Body

Context

Taylor (1990) investigates how aircrew understand "situational awareness" and develops tools for its subjective estimation, with the aim of quantifying and validating design objectives for crew-systems integration. Within this knowledge base the chapter is the SA-measurement complement to the theoretical SA model in Situation Awareness (Endsley) and the methodological sibling of Nasa Tlx, which does for workload what SART does for situation awareness. It connects to Aviation Human Factors through its aircrew focus and to Mental Workload through the workload-vs-SA distinction that motivated the work.

Key Points

(Abstract-sourced pending the full chapter. Page locators will be added once the PDF is in RAW.)

Definition of SA. Taylor defines situation awareness as "the knowledge, cognition and anticipation of events, factors and variables affecting the safe, expedient and effective conduct of the mission" (abstract; chapter pp. 111–128).

Method. The instrument was derived empirically. Eighty-four Test and Operational Royal Air Force aircrew were interviewed in three phases — Scenario Generation, Construct Elicitation, and Construct Structure Validation — in semi-structured sessions run by psychologists to a fixed knowledge-elicitation protocol based on the Personal Construct / Repertory Grid technique. The construct/scenario ratings obtained during construct elicitation were analysed by Principal Components Analysis with Varimax factor rotation (abstract; chapter pp. 111–128).

Purpose. The technique is intended to provide subjective estimates of SA that assist in the quantification and validation of design objectives for crew-systems integration — extending subjective measurement from workload to situation awareness (abstract; chapter pp. 111–128).

Conclusion

Taylor (1990) develops SART as a subjective, empirically-grounded instrument for measuring situation awareness in aircrew systems design, broadening human-engineering measurement beyond workload. The detailed dimensional structure of the published instrument (commonly summarised as the constructs of demand on, and supply of, attentional resources together with understanding) should be confirmed against the chapter text before being stated here.

Open Questions

  • What are the exact SART dimensions and how are they combined into an overall SA score? (Requires the chapter PDF.)
  • How does SART compare with Endsley's SAGAT (a query-based, objective SA measure) in sensitivity and validity?
  • Does the workload-vs-SA dissociation hold across the operational domains beyond RAF aircrew?
