DALI QuestionnaireInstructions:Throughout this experiment the rating scales are used to assess your experiences inthe different task conditions. Scales of this sort are extremely useful, but their utilitysuffers from the tendency people have to interpret them in individual ways. Forexample, some people feel that mental or temporal demands are the essentialaspects of workload regardless of the effort they expended on a given task or thelevel of performance they achieved. Others feel that if they performed well theworkload must have been low and if they performed badly it must have been high.Yet others feel that effort or feelings of frustration are the most important factors inworkload; and so on. The results of previous studies have already found everyconceivable pattern of values. In addition, the factors that create levels of workloaddiffer depending on the task. For example, some tasks might be difficult becausethey must be completed very quickly. Others may seem easy or hard because of theintensity of mental or physical effort required. Yet others feel difficult because theycannot be performed well, no matter how much effort is expended.The evaluation you are about to perform is adapted by a technique that hasbeen developed by NASA to assess the relative importance of six factors indetermining how much workload you experienced. The procedure is simple: You willbe presented with a series of pairs of rating scale titles (for example, Effort vs. MentalDemands) and asked to choose which of the items was more important to yourexperience of workload in the task(s) that you just performed. Each pair of scale titleswill appear on a separate card.Circle the Scale Title that represents the more important contributorto workload for the specific task(s) you performed in this experiment.After you have finished the entire series we will be able to use the pattern ofyour choices to create a weighted combination of the ratings from that task into asummary workload score. Please consider your choices carefully and make themconsistent with how you used the rating scales during the particular task you wereasked to evaluate. Don't think that there is any correct pattern: we are onlyinterested in your opinions.If you have any questions, please ask them now. Otherwise, start whenever youare ready. Thank you for your participation.XV
