This paper describes the origins and history of multiple resource theory in accounting for differences in dual task interference. [...] Key Method A computational rendering of this model is then presented. Examples are given of how the model predicts interference differences in operational environments. Finally, three challenges to the model are outlined regarding task demand coding, task allocation and visual resource competition.Expand
Flexible attention allocation to visual and auditory working memory tasks: manipulating reward induces a trade-off
TLDR
The results show patterns of interference consistent with a trade-off between the tasks, suggesting that a shared resource can be flexibly divided, rather than only fully allotted to either of the tasks. Expand
Interference between a fast-paced spatial puzzle task and verbal memory demands
TLDR
Investigating whether a spatial puzzle task performed simultaneously with a verbal recall task would impair performance in either task or both tasks, compared to performance on the tasks individually found a reduction in word recall when dual-tasking. Expand
Cognitive Load in Cross‐Modal Dual‐Task Processing
Summary Unitary-resource models posit a collective attentional resource responsible for sustaining information processing across all modalities. In contrast, multiple-resource models presume aExpand
Motor-cognitive dual-task performance: effects of a concurrent motor task on distinct components of visual processing capacity
TLDR
The results support a capacity sharing account of motor-cognitive dual tasking and suggest that even performing a relatively simple motor task relies on central attentional capacity that is necessary for efficient visual information uptake. Expand
Derivation and Demonstration of a New Metric for Multitasking Performance
TLDR
A theory-driven, quantitative, individual-level estimate of the degree to which cognitive processes are degraded or enhanced when multiple tasks are simultaneously completed is proposed and demonstrated. Expand
Task-specificity and resource allocation in information perception in three-dimensional space
TLDR
Two studies examine whether optimal display location depends on the task, which is being executed and whether it is generally beneficial to present concurrent information in dual-task situations in two instead of one perceptual depth plane in order to optimize resource utilization. Expand
Resilience of perceptual metacognition in a dual-task paradigm.
TLDR
This work investigates the resilience of metacognition to multitasking costs, and examines how the results fit onto current models of perceptual metac Cognition. Expand
Task-specificity and resource allocation in information perception in three-dimensional space
TLDR
Two studies examine whether optimal display location depends on the task, which is being executed and whether it is generally beneficial to present concurrent information in dual-task situations in two instead of one perceptual depth plane in order to optimize resource utilization. Expand
Predicting interference in concurrent multitasking
TLDR
A computational cognitive model was developed that was fit on single-task performance and generated a priori predictions of behavior that closely matched the behavioral data, indicating that models designed for single tasks can indeed account for performance degradation in dual-task situations. Expand
The impact of predictability on dual-task performance and implications for resource-sharing accounts
TLDR
Examination of the impact of predictability on dual-task performance by systematically manipulating predictability in either one of two tasks, as well as between tasks shows that resources were shared better between tasks. Expand

Task-Sharing within and between Hemispheres: A Multiple-Resources Approach
TLDR
It is proposed that each cerebral hemisphere accesses an independent resource supply that can be shared among many types of tasks, including those with no obvious similarities. Expand
Codes and Modalities in Multiple Resources: A Success and a Qualification
TLDR
An experiment in which either verbal or spatial decision tasks, responded to with either voice or keypress, were time-shared with second-order tracking provided support for the importance of the dichotomy between verbal and spatial processing codes in accounting for task interference. Expand
Compatibility and Resource Competition between Modalities of Input, Central Processing, and Output
TLDR
Synthesized auditory displays and speech recognizers were used in two experiments to develop guidelines for their implementation in military aircraft to examine competition between tasks for encoding and response modalities and the optimum assignment of modalities to a given task. Expand
Visual scanning with or without spatial uncertainty and divided and selective attention.
TLDR
Evidence is provided that visual scanning as a spatial exploratory activity produces greater task interference with concurrent spatial tasks than with verbal tasks, and spatial uncertainty in scanning is identified to be the crucial factor in producing this differential effect. Expand

A dual-task paradigm is used to investigate whether the auditory input logogen is distinct from the articulatory output logogen. In the first two experiments it is shown that the task of detecting anExpand
P300 and tracking difficulty: evidence for multiple resources in dual-task performance.
TLDR
The P300 component of the event-related potentials elicited by the tones was examined to determine the extent to which its amplitude was affected by variations in the forcing-function bandwidth, or difficulty, of the tracking task. Expand

Two experiments were conducted to extend earlier time-sharing results of Kantowitz and Knight (1974) and support a hybrid processing model with serial and parallel arrangements of stages. Expand

TLDR
The single-channel hypothesis holds that the central decision mechanism can deal with data from only one signal, or group of signals, at a time, so that data from a signal arriving during the reaction time to a previous signal have to wait until the decision mechanism becomes free. Expand
