Two experiments are reported in which subjects performed two forced-paced serial reaction time tasks separately and together at their maximum sustainable rates of information processing. Experiment 1 investigated the effects on the relationship between single- and dual-task performance of using tasks with the same or different input and output modality characteristics; an additional condition tested the effects on this relationship of using tasks with higher S–R compatibility. Experiment 2… Expand

Research on task switching and dual-task performance has spawned two lit- eratures that have, to a surprising extent, developed independently. This tutorial reviews the principal findings of eachExpand
Task switching and multitask performance.
TLDR
This tutorial reviews the principal findings of each tradition and considers how these phenomena may be related, including the possibility that queuing might stem from an inability to maintain two distinct task sets at the same time. Expand
Dual Task Performance
TLDR
A brief review on human performance in dual—or even multiple—task conditions, where performance varies from almost perfect timesharing to strict serial handling of either task. Expand
Processing bottlenecks in dual-task performance: Structural limitation or strategic postponement?
TLDR
A new paradigm is examined in which subjects are told to place equal emphasis on both tasks and to emit both responses at about the same time, showing patterns of interference that cannot easily be attributed to strategic postponement, preparation effects, or conflicts in response production.

Sharing verbal and visuospatial resources in working memory.

TLDR
The results of a test of resource capacity theories support neither single nor multiple resource models, but can be explained with reference to component processes in working memory. Expand
Control of Cognitive Processes
One of the most challenging problems facing cognitive psychology and cognitive neuroscience is to explain how mental processes are voluntarily controlled, allowing the computational resources of theExpand
Speech Shadowing While Driving
TLDR
It is demonstrated that people process auditory information more efficiently (with a lower overall dual-task decrement) when relevant auditory and visual stimuli are presented from the same, rather than different, spatial locations. Expand
A Broader Application of the Detection Response Task to Cognitive Tasks and Online Environments
TLDR
The MOT task provides an effective manipulation of cognitive workload and the DRT is sensitive to changes in workload across a range of settings and is suitable to use outside of driving scenarios, as well as via online delivery. Expand
Principles of cross-modal competition: Evidence from deficits of attention
TLDR
A differentiated attentional system in which competition is modulated by the level of stimulus representation to which attention is directed is revealed. Expand
Human multitasking
Humanmultitasking is the apparent performance by an individual of handling more than one task, or activity, at the same time. The term is derived from computer multitasking. An example ofExpand

A Dual Task Response Modality Effect: Support for Multiprocessor Models of Attention
In Experiment I two groups of 11 men performed a continuous visual input/manual output task simultaneously with a two-choice tone identification task. One group responded vocally to the tones; oneExpand
Individual Differences in Multiple-Task Performance as a Function of Response Strategy
TLDR
Comparisons among subjects using the same strategy indicate that subjects who use the massed response strategy naturally do not perform as well under multiple-task conditions as do the other subjects, although their single-task performance is not significantly poorer. Expand
On the Division of Attention: A Disproof of the Single Channel Hypothesis
TLDR
In two experiments reported here, it is shown that people can attend to and repeat back continuous speech at the same time as taking in complex, unrelated visual scenes, or even while sight-reading piano music. Expand
TIME-SHARING REVISITED: TEST OF A COMPONENTIAL MODEL FOR THE ASSESSMENT OF INDIVIDUAL DIFFERENCES
Abstract Time-sharing ability as an individual differences variable in dual task performance was examined using a componential model. Five proposed components were assessed: (1) serial processingExpand
On data-limited and resource-limited processes
TLDR
The principles discussed show that conclusions about the interactions among psychological processes must be made with caution, and some existing assumptions may be unwarranted, as well as resulting in some new interpretations of interactions among competing psychological processes. Expand

TLDR
Performance under divided attention will reflect an interaction between resource limitation, single task processes, and emergent aspects of the whole situation. Expand
MEMORY AND THOUGHT IN HUMAN INTELLECTUAL PERFORMANCE.
  • M. Posner
  • Psychology, Medicine

TLDR
This paper is a review of efforts to extend the use of information techniques to tasks which are intellectual in nature and considers the difficulty of transformations such as occur in arithmetic operations and concept utilization in terms of their informational parameters. Expand
Dual Task Methods of Assessing Work-load
TLDR
The technique appears to be valid and useful for the study of individual differences in processing resources when the additional task is secondary, presents discrete stimuli which impose constant load, is carried out at a forced pace and competes with the primary task for processing resources only.

TLDR
A model is presented for the limitations of processing information by the human operator which proposes that he acts not as a limited capacity channel with fixed capacity, but as aLimited capacity processor where the total capacity is not exceeded, and where there is high compatibility. Expand
