Dynamics of the central bottleneck: Dual-task and task uncertainty
- PLoS Biology
, 2006
"... Why is the human brain fundamentally limited when attempting to execute two tasks at the same time or in close succession? Two classical paradigms, psychological refractory period (PRP) and task switching, have independently approached this issue, making significant advances in our understanding of ..."

in order to proceed with the next one). Our results clarify the chronometric relations between these central components of dual-task processing, and in particular whether they operate serially or in parallel. On this basis, we propose a hierarchical model of cognitive architecture that provides a synthesis
Age Differences in Dual-Task Performance After Practice
"... This study investigated whether older adults could acquire the ability to perform 2 cognitive operations in parallel in a paradigm in which young adults had been shown to be able to do so (K. Oberauer & R. Kliegl, 2004). Twelve young and 12 older adults practiced a numerical and a visuospatial c ..."

continuous memory updating task in single-task and dual-task conditions for 16 to 24 sessions. After practice, 9 young adults were able to process the 2 tasks without dual-task costs, but none of the older adults had reached the criterion of parallel processing. The results suggest a qualitative difference
Graded capacity-sharing in dual-task interference
- Journal of Experimental Psychology: Human Perception and Performance
, 1994
"... Research suggests that dual-task interference is caused by a central bottleneck (together with response grouping and impaired preparation). The emphasis placed on the first response in these experiments, however, may have discouraged the sharing of processing resources between tasks. In the present ..."

Effect of dual tasks on balance ability in stroke patients
"... Abstract. [Purpose] The purpose of this study was to determine the effects of training using dual tasks on bal-ance ability in stroke patients. [Subjects] Forty stroke patients were divided into a dual-task training group (N = 20) and a single task training group (N = 20) randomly. [Methods] The sub ..."

Dual-Task Performance as a Measure for Mental Effort
- in Library Searching and Web Searching. Proceedings of the 68th Annual Meeting of the American Society for Information Science and Technology
, 2005
"... This paper examines a dual-task method for the assessment of mental effort during online searching, having the users engage in two tasks simultaneously. Searching was assigned as a primary task and a visual observation was set up as a secondary task. The study participants were asked to perform two ..."

Lexical Frequency Effects in Dual-Task Picture Naming
"... Lexical frequency effects were examined in the context of the central bottleneck (CB) model of dual-task performance. Two dual-task experiments were conducted. In Experiment 1, picture naming was the primary task and tone identification was secondary. Lexical frequency affected reaction time (RT) to ..."

Flexibility and Processing Codes in Dual-task Scenarios

While researchers have begun to address issues surrounding good auditory display design as well as potential domains of application, little is known about the cognitive processes invol ..."

of information may persist. Surprisingly few studies to date have examined auditory information display in dual-task scenarios. This study examined the flexibility of encoding of information and processing code conflicts in a dual-task paradigm with auditory graphs—a specific class of auditory displays
