Selecting measures is a necessary component of human factors research. Proper selection must take into account the representation problem (how is the assignment of numbers to objects or phenomena justified?) and the uniqueness problem (to what degree is this assignment unique?). Other key human factors measurement issues include subject representativeness,(More)
Various techniques have been developed to predict and measure pilot workload. This simulation was conducted in order to compare four widely used methods: a visual two-and four-choice reaction time task, time production, retrospective multi-dimensional subjective ratings and in-flight verbal workload estimates. Two scenarios with different levels of(More)
Twenty-four male subjects performed a discrete positioning task using an isometric controller. Two levels of order of control (position and velocity) were factorially crossed with two levels of control-display gain. Fitts' law functions were found for each of the four conditions. The velocity control conditions had significantly steeper slopes than the(More)
Experiments examining the issue of decay in short-term memory have assumed a single undifferentiated source of processing capacity which cannot be devoted to rehearsal when consumed in the processing of a nonverbal interpolated task. Three experiments reported here call this logic into question, since variations in difficulty in the nonverbal interpolated(More)
While recent developments in telematics have produced great interest in driver distraction, this is hardly a new topic. An early UMTRI report (Treat, 1980) defined internal distraction as a diversion of attention from the driving task that is compelled by an activity or event inside the vehicle. Based on data collected in Monroe County Indiana, Treat (1980)(More)
Many in-vehicle information systems (IVIS) are developed without consideration of how components need to be integrated. This can increase the cognitive load, errors and annoyance for drivers. This paper presents a taxonomy of IVIS functions and describes the information flows associated with these functions to show how a network analysis can guide(More)
Memory retention of drivers was tested for trafficand traveler-related messages displayed on an in-vehicle information system (IVIS). Three research questions were asked: (a) How does in-vehicle visual message format affect comprehension? (b) How does message format affect memory retention? and (c) What impact does driver age have on recall of in-vehicle(More)
