Although increases in the use of automation have occurred across society, research has found that human operators often underutilize (disuse) and overly rely on (misuse) automated aids (R. Parasuraman & V. Riley, 1997). Nearly 275 Cameron University students participated in 1 of 3 experiments performed to examine the effects of perceived utility (M. T.(More)
BACKGROUND It was proposed that misuse and disuse often occur because operators (a) cannot determine if automation or a nonautomated alternative maximizes the likelihood of task success (appraisal errors) or (b) know the utilities of the options but disregard this information when deciding to use automation (intent errors). OBJECTIVE This investigation(More)
OBJECTIVE This investigation examined the impact of human-machine competition (John Henry effects) on intent errors. John Henry effects, expressed as an unwillingness to use automation, were hypothesized to increase as a function of operators' personal investment in unaided performance. BACKGROUND Misuse and disuse often occur because operators (a) cannot(More)
In 1920, John Watson and Rosalie Rayner claimed to have conditioned a baby boy, Albert, to fear a laboratory rat. In subsequent tests, they reported that the child's fear generalized to other furry objects. After the last testing session, Albert disappeared, creating one of the greatest mysteries in the history of psychology. This article summarizes the(More)
Evidence collected by Beck, Levinson, and Irons (2009) indicates that Albert B., the "lost" infant subject of John B. Watson and Rosalie Rayner's (1920) famous conditioning study, was Douglas Merritte (1919-1925). Following the finding that Merritte died early with hydrocephalus, questions arose as to whether Douglas's condition was congenital, rather than(More)

Assessments of the magnitude of performance loss caused by injury or disease necessarily involve a comparison of a person's performance before and after the onset of impairment. Well-established procedures are available for measuring current performance on a variety of evaluation instruments. However, few actuarial methods have been developed for estimating(More)
