“…The notion that people can trade response time for accuracy in any task has been well-documented (Fitts, 1966;Garret, 1922;Hick, 1952;Ollman, 1966;Pachella & Pew, 1968;Pew, 1969;Schouten & Bekker, 1967;Wickelgren, 1977;Woodworth, 1899). At the heart of the problem is the fact that individual participants respond per an unknown internal criterion that is likely to be dynamic over time.…”

“…However, the existing literature shows that they are often not statistically independent of each other, and moreover the relationship is sometimes complex, and subject to individual differences. Since RT and accuracy are variables derived from the same decision process with an unknown and dynamic criterion, it seems conceptually difficult to regard them as independent variables, and ideally, statistical models of RT and accuracy should reflect this (Fitts, 1966;Pachella & Fisher, 1969;Pachella & Pew, 1968;Pew, 1969;Ratcliff, 1985;Ratcliff & Hacker, 1981;Ratcliff & Rouder, 1998;Wickelgren, 1977). Many researchers consider qualitatively whether a tradeoff between RT and accuracy is present in their data, at least at the level of group or condition averages.…”

a b s t r a c t a r t i c l e i n f oIn psycholinguistic studies using error rates as a response measure, response times (RT) are most often analyzed independently of the error rate, although it is widely recognized that they are related. In this paper we present a mixed effects logistic regression model for the error rate that uses RT as a trial-level fixed-and random-effect regression input. Production data from a translation-recall experiment are analyzed as an example. Several model comparisons reveal that RT improves the fit of the regression model for the error rate. Two simulation studies then show how the mixed effects regression model can identify individual participants for whom (a) faster responses are more accurate, (b) faster responses are less accurate, or (c) there is no relation between speed and accuracy. These results show that this type of model can serve as a useful adjunct to traditional techniques, allowing psycholinguistic researchers to examine more closely the relationship between RT and accuracy in individual subjects and better account for the variability which may be present, as well as a preliminary step to more advanced RT-accuracy modeling.

Abstract-We propose an optimization framework to study two fundamental attention control aspects in human-robot systems: Where and how much attention should the operator allocate? In other words, which information source should be observed by the operator, and how much time duration should be allocated to the information feed in order to optimize the overall performance of the human-robot system? The proposed framework incorporates (i) operator performance constraints, such as error rates and service times based utilization history, (ii) sensor constraints, such as processing/travel time, and (iii) task constraints, such as prioritization. We use a receding horizon approach to solve the resulting dynamic program, leading to efficient policies for operator time duration allocation and sensor selection. We demonstrate our methodology in a distributed surveillance problem.

“…Pew [8] originally used the SAOC to describe accuracy in choice reaction tasks, but it has since been used (though not widely) in a range of timed reaction tasks. Rival [21] is one of the few investigators who has used the SAOC to show performance in a pointing task under different speed-accuracy settings.…”

Using the Speed-Accuracy Operating Characteristic to Visualize Performance with Pointing Devices

There is a nearly limitless variety of alternatives to the traditional computer mouse, including trackballs, trackpads, joysticks, head-mounted mouse emulators, and eye-gaze systems, each with its own unique strengths and limitations. Two key challenges in selecting the most appropriate pointing device are (1) collecting accurate, comparable data describing the client's performance with each device under consideration and (2) aggregating, analyzing and displaying the data in a format that allows the client, clinician and other interested parties to make an accurate decision. Tools exist for collecting data, but there has been limited research on how to visualize and compare performance data. The investigator has been exploring the use of the speed-accuracy operating characteristic (SAOC) as a means of comparing performance on computer pointing tasks between different pointing devices (e.g., mouse, trackball, touchpad). The SAOC is a graphical representation of the trade-off between speed and accuracy that has been used in a range of timed reaction tasks, including pointing tasks. The SAOC is easy for clinicians, clients and third-party payers to interpret, and provides an efficient means of summarizing and documenting performance but does not replace clinical judgement or eliminate the need for clinician-client interaction.
