virtually perfect time sharing in dual Task Performance uncorking the central cognitive bottleneck
Psychological Science, 2001Co-Authors: Eric H Schumacher, David E. Kieras, Jennifer M Glass, Erick J Lauber, Travis L Seymour, David E Fencsik, David E. MeyerAbstract:A fundamental issue for psychological science concerns the extent to which people can simultaneously perform two perceptual-motor Tasks. Some theorists have hypothesized that such dual-Task Performance is severely and persistently constrained by a central cognitive “bottleneck,” whereas others have hypothesized that skilled procedural decision making and response selection for two or more Tasks can proceed at the same time under adaptive executive control. The three experiments reported here support this latter hypothesis. Their results show that after relatively modest amounts of practice, at least some participants achieve virtually perfect time sharing in the dual-Task Performance of basic choice reaction Tasks. The results also show that observed interference between Tasks can be modulated by instructions about differential Task priorities and personal preferences for daring (concurrent) or cautious (successive) scheduling of Tasks. Given this outcome, future research should investigate exactly when a...

Psychological Science, 2001Co-Authors: Eric H Schumacher, David E. Kieras, Jennifer M Glass, Erick J Lauber, Travis L Seymour, David E Fencsik, David E. MeyerAbstract:A fundamental issue for psychological science concerns the extent to which people can simultaneously perform two perceptual-motor Tasks. Some theorists have hypothesized that such dual-Task Performance is severely and persistently constrained by a central cognitive "bottle-neck," whereas others have hypothesized that skilled procedural decision making and response selection for two or more Tasks can proceed at the same time under adaptive executive control. The three experiments reported here support this latter hypothesis. Their results show that after relatively modest amounts of practice, at least some participants achieve virtually perfect time sharing in the dual-Task Performance of basic choice reaction Tasks. The results also show that observed interference between Tasks can be modulated by instructions about differential Task priorities and personal preferences for daring (concurrent) or cautious (successive) scheduling of Tasks. Given this outcome, future research should investigate exactly when and how such sophisticated skills in dual-Task Performance are acquired.

a computational theory of executive cognitive processes and multiple Task Performance part 1 basic mechanisms
Psychological Review, 1997Co-Authors: David E. Meyer, David E. KierasAbstract:Abstract : Persistent controversies about human multiple Task Performance suggest that research on it will benefit from increased use of precise computational models. Toward this objective, the present report outlines a comprehensive theoretical framework for understanding and predicting the Performance of concurrent perceptual motor and cognitive Tasks. The framework involves an Executive Process Interactive Control (EPIC) architecture, which has component modules that process information at perceptual, cognitive, and motor levels. On the basis of EPIC, computational models that use a production system formalism may be constructed to simulate multiple Task Performance under a variety of conditions. These models account well for reaction time data from representative paradigms such as the psychological refractory period (PRP) procedure. With modest numbers of parameters, good fits between empirical and simulated reaction times support several key conclusions: (1) at a cognitive level, people can apply distinct sets of production rules simultaneously for executing the procedures of multiple Tasks; (2) there is no immutable central response selection or decision bottleneck; (3) people's capacity to process information and take action at peripheral perceptual motor levels is limited; (4) to cope with such limits and to satisfy Task priorities, flexible scheduling strategies are used; (5) these strategies are mediated by executive cognitive processes that coordinate concurrent Tasks adaptively. The initial success of EPIC and models based on it suggest that they may help characterize multiple Task Performance across many domains, including ones that have substantial practical relevance.

adaptive executive control flexible multiple Task Performance without pervasive immutable response selection bottlenecks
Acta Psychologica, 1995Co-Authors: David E. Meyer, David E. Kieras, Jennifer M Glass, Erick J Lauber, Eric H Schumacher, Eileen L Zurbriggen, Leon Gmeindl, Dana ApfelblatAbstract:Abstract A new theoretical framework, the EPIC (Executive-Process/Interactive-Control) architecture, provides the basis for accurate detailed computational models of human multiple-Task Performance. Contrary to the traditional response-selection bottleneck hypothesis, EPIC's cognitive processor can select responses and do other procedural operations simultaneously for multiple concurrent Tasks. Using this capacity together with flexible executive control of peripheral perceptual-motor components, EPIC computational models account well for various patterns of mean reaction times, systematic individual differences in multiple-Task Performance, and influences of special training on people's Task-coordination strategies. These diverse phenomena, and EPIC's success at modeling them, raise strong doubts about the existence of a pervasive immutable response-selection bottleneck in the human information-processing system. The present research therefore helps further characterize the nature of discrete versus continuous information processing.
