On the uninterpretability of dual-task performance
Journal of Experimental Child Psychology, 1989Abstract In this commentary, we argue that dual-task performance is currently not interpretable. The argument is based on the assumption that a number of plausible and compatible hypotheses have been offered to account for dual-task interference. Our present state of theoretical development does not permit us to discriminate among the alternative ...

The role of feedback delay in dual-task performance
Psychological Research, 2017Doing two things at once is hard, and it is probably hard for various reasons. Here we aim to demonstrate that one so far barely considered reason is the monitoring of sensory action feedback, which detracts from processing of other concurrent tasks. To demonstrate this, we engaged participants in a psychological refractory period paradigm.

Aging and dual-task performance: A meta-analysis.
Psychology and Aging, 2003The relations between dual-task effects and aging were examined through a meta-analysis of 33 studies (with 48 independent participant groups) using latency as the dependent measure and 30 studies (with 40 independent participant groups) focusing on accuracy.

Dual-task performance during a climbing traverse
Experimental Brain Research, 2011High-angle climbing is a physically and cognitively challenging activity. Whilst researchers have examined the physiological demands of climbing, the cognitive demands have been relatively neglected. In this experiment, we examined the performance of climbers when required to perform a dual climbing and word memory task, relative to single-task ...

Localizing practice effects in dual-task performance
Quarterly Journal of Experimental Psychology, 2007Practice effects on dual-task processing are of interest in current research because they may reveal the scope and limits of parallel task processing. Here we used onsets of the lateralized readiness potential (LRP), a time marker for the termination of response selection, to assess processing changes after five consecutive dual-task sessions with ...

Brain Laterality and Dual-Task Performance
Perceptual and Motor Skills, 1985There is substantial evidence that the right brain is superior for the perception of space and form, while the left possesses greater language capabilities. One model of information processing based on the lateralized function of each hemisphere proposes that the brain operates most efficiently with direct access (lateralized input) of the appropriate ...

Is Dual-Task Performance Necessarily Impaired in Space?
Human Factors: The Journal of the Human Factors and Ergonomics Society, 2000Recent single-subject experiments in space have reported impaired dual-task performance that could result from either a direct effect of microgravity on the central nervous system or from the multistressor environment. We sought to distinguish between these hypotheses using 6 astronauts in the 16-day NASA Neurolab mission, testing them at intervals ...

Hemisphere function and dual task performance
Neuropsychologia, 1979Abstract Two experiments are described in which the effects of a visual monitoring task on concurrently performed manual sorting tasks were investigated. In the first experiment, monitoring visual input directed to a single celebral hemisphere did not differentially impair unimanual sorting by the contralateral or ipsilateral hand.

Dual-task performance in late proficient bilinguals
Laterality: Asymmetries of Body, Brain and Cognition, 2008A dual task, consisting of speeded tapping during concurrent silent and aloud reading, was employed to investigate hemispheric specialisation for both first (L1) and second (L2) language in late proficient bilinguals living in the L2 environment.

Involuntary strategy-dependent dual task performance
Psychological Research, 2011Previous studies showed that some dual tasks can be performed simultaneously without costs. Yet, a variable SOA between the inputs to such tasks leads to strategic, often involuntary, prioritization of one of the two tasks. Here we explore the boundary conditions for this involuntary or exogenous strategy.
