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 determine if automation or a nonautom...

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 assessed the effectiveness of performanc...

Two experiments explored the effects of ingroup vs outgroup performance on the extent to which individuals value an attribute. Self-appraisals of personal standing on the attribute were examined as a potential mediator of this relationship. In both experiments, members of two groups (either experimentally created or gender groups) took a test of a bogus personality trait and received feedback a...

The purpose of this study was to compare the effect of structured training on recognition and appraisal of the timbre (tone quality) of musical instruments by postlingually deafened cochlear implant recipients. Twenty-four implant users (Nucleus CI24M) were randomly assigned to a control or a training group. The control group experienced only incidental exposure to music in their usual daily ro...

A sample of licensed pilots completed the Aeronautical Risk Judgment Questionnaire (ARJQ) which was developed to obtain data on pilots' perceptions of their abilities, willingness to take risks, hazard awareness, and judgments of the risks of general aviation. A subset of these subjects was tested on a computerised test of flight decision-making involving a proposed VFR flight in marginal weath...

Clinical guidelines are usually written as text documents that are meant for human consumption. Implementing clinical guidelines as decision-support systems that deliver patient-specific advice at the point of care could increase the effectiveness of clinical guidelines. Several researchers studied the transition from narrative guidelines to computer-interpretable guidelines and have identified...

Accurately recognizing users’ affective states could contribute to more productive and enjoyable interactions, particularly for task-oriented learning environments. In addition to using physiological data, affect recognition models can leverage knowledge of task structure and user goals to effectively reason about users’ affective states. In this paper we present an inductive approach to recogn...

this article reports on the findings of a study that investigated the impact of manipulating task performance conditions on listening task performance by learners of english as a foreign language (efl). the study was designed to explore the effects of changing complexity dimensions on listening task performance and to achieve two aims: to see how listening comprehension task performance was aff...
