Development of NASA-TLX (Task Load Index): Results of Empirical and Theoretical Research

  title={Development of NASA-TLX (Task Load Index): Results of Empirical and Theoretical Research},
  author={S. G. Hart and Lowell E. Staveland},
  journal={Advances in psychology},
Abstract The results of a multi-year research program to identify the factors associated with variations in subjective workload within and between different types of tasks are reviewed. Subjective evaluations of 10 workload-related factors were obtained from 16 different experiments. The experimental tasks included simple cognitive and manual control tasks, complex laboratory and supervisory control tasks, and aircraft simulation. Task-, behavior-, and subject-related correlates of subjective… Expand

An Empirical Validation of Subjective Workload Ratings
The results indicated the number of concurrent tasks had the largest impact on subjective workload ratings, and in terms of multiple resource theory, spatial, verbal, and visual demands contributed the most variance. Expand
Nasa-Task Load Index (NASA-TLX); 20 Years Later
NASA-TLX is a multi-dimensional scale designed to obtain workload estimates from one or more operators while they are performing a task or immediately afterwards. The years of research that precededExpand
The Prediction of Pilot Subjective Workload Ratings
This paper investigated potential variables that predict pilot subjective workload ratings. A correlational design was used to regress NASA TLX subjective workload ratings onto four independentExpand
Subjective Task Complexity and Subjective Workload: Criterion Validity for Complex Team Tasks
The criterion validity of the NASA Task Load indeX (TLX) and a previously developed subjective Task Complexity Index (TCI) were studied and indicated stronger criterion validity for the subjective task complexity measure than for the TLX. Expand
A comparison of two scoring procedures with the NASA task load index in a simulated flight task
Two issues which pertain to NASA task load index (TLX) application procedures and scoring techniques were investigated. One issue concerned the procedure used to combine ratings on the TLX dimensionsExpand
Modeling the Workload-Performance Relationship
This work develops algorithms using data from four new studies investigating change in performance as demands on mental resources increase, and proposes a way forward in modeling performance as a function of workload in IMPRINT. Expand
Comparison of Four Subjective Workload Rating Scales
Four subjective workload scales were compared along four dimensions: sensitivity, operator acceptance, resource requirements, and special procedures. The scales were the Modified Cooper-Harper scale,Expand
Establishing Workload Manipulations Utilizing a Simulated Environment
This experiment successfully identified task demand manipulations that can be used to investigate operator workload within realistically complex environments and revealed that the event rate manipulations had the most consistent impact on performance and subjective workload ratings in both tasks. Expand
A self-analysis of the NASA-TLX workload measure
It was found that there is a significant difference between the workload scores for the two media, with the computer version of the NASA-TLX incurring more workload. Expand
A comparison of the Subjective Workload Assessment Technique (SWAT) and the NASA-Task Load Index (TLX) under immediate and delayed rating conditions
The sensitivity and ease-of-use results suggest possible trade-offs in the selection of a subjective rating measurement technique, which may be associated with the type of task to be rated and its demand levels, as well as with the environment in which the task is to be performed. Expand


Predicted versus experienced workload and performance on a supervisory control task
The results have indicated that an operator might correctly predict the workload of a realistically complex task if he is familiar with the basic system, and the design, functional requirements, and operational procedures of the proposed modifications are described clearly. Expand
Individual Differences in Multiple-Task Performance and Subjective Estimates of Workload
This experiment examined the relation between individual differences in multiple-task performance and subjective estimates of workload. 30 women performed various complex tasks alone and together andExpand
Model-Based Estimation and Prediction of Task-Imposed Mental Workload
Mental workload has been an area of intensive research for better than a decade. One specific area of interest in aircrew related workload research is concerned with the development of quantitativeExpand
Assessing the Subjective Workload of Directional Orientation Tasks
The impact of various flight-related tasks on the workload imposed by the requirement to compute new headings, course changes, and reciprocal headings was investigated. Eight pilots were presentedExpand
Measuring pilot workload in a motion base trainer. A comparison of four techniques.
Four widely used methods to predict and measure pilot workload were compared: a visual two-and four-choice reaction time task, time production, retrospective multi-dimensional subjective ratings and in-flight verbal workload estimates. Expand
The Reliability and Validity of Flight Task Workload Ratings
Twelve instrument-rated general aviation pilots each flew two scenarios in a motion-base simulator. During each flight, the pilots verbally estimated their workload every three minutes. FollowingExpand

Rating Consistency and Component Salience in Subjective Workload Estimation
Abstract : Twelve general aviation pilots participated in a two-day experiment performing four tasks intended to load on different cognitive, perceptual, and motor dimensions. The tasks were variedExpand
Automation - Changes in cognitive demands and mental workload
The automation is shown to improve objective performance and lower subjective workload significantly in the combined FC/TA task, but not in the FC task alone or in theFC/EF task. Expand
Memory and subjective workload assessment
Recent research suggested subjective introspection of workload is not based upon specific retrieval of information from long term memory, and only reflects the average workload that is imposed uponExpand
