Synopsis: "The principal objective of this research is to provide basic empirical evidence on how selected factors influence automation use decisions." Four complementary experiments were performed. "The primary objectives of Experiment One were to investigate the effects of workload, task uncertainty (as a manipulation of self confidence), and automation reliability (as a manipulation of operator trust in the automation) on operator tendencies to use automation." The subjects used in "Experiment One were thirty, University of Minnesota students ... The primary objective of Experiment Three was to compare how professional commercial transport aircraft pilots use automation with how students use it. This comparison is intended to provide insight regarding automation use biases that may result from two levels of experience with automation. ... Thirty four commercial transport pilots from a major airline participated in the study. All pilots were current on an advanced technology aircraft (Boeing 737-300, Boeing 757, or Airbus A320) ... Experiment Three was a replication of Experiment One" and the results of Experiment One were compared to the results of Experiment Three. "Each experiment included a computer-based task, in which subjects had to decide whether or not to rely on automation to perform the task, and a series of questionnaires. ... The computer-based task phase of the experiment consisted of a simple computer game and a gambling task. ... The game phase of the experiment consisted of two tasks which the subject had to perform simultaneously. One of the tasks could be turned over to or taken back from automation at the subject's discretion. The other task required constant attention as a workload manipulation. ... The game phase of the experiment required one hour to perform. There were 2050 trials of 1.75 seconds each. After the game phase, the subject was given an opportunity to gamble for more points. This was intended as an objective measure of risk taking, to be compared with the risk questionnaire results. ... Two questionnaires were used to investigate how individual differences in acceptance of risk and attitudes toward automation might affect automation use. The risk questionnaire used was the Choice Dilemma Questionnaire (Kogan and Wallach, 1964). ... The automation attitudes questionnaire was the Complacency-Potential Rating Scale (Singh and all, 1993)."
