The Development of Dual Task Performance
The development of dual task performance was investigated in terms of the contribution of single task level of performance and a time sharing skill on dual task performance across age groups and stages of learning. 160 boys and girls, 6-7 and 8-9 years old from public schools in S. Paulo, Brazil, …

Dual task performance and antihistimine use
… sedative effects as well as impair psychomotor performance. Performance testing of antihistamines, however, has not produced reliable evidence that there are behavioral effects at therapeutic dose levels. Therefore, the objective of this research was to determine whether a complex cognitive and …

Hemispheric Effects of Verbal Information Processing on Single and Dual Task Performance
<p>Several theories have been proposed to predict performance when operators time share tasks. The Hemispheres as Resources Model suggests tasks will be performed efficiently together if each hemisphere allocates resources to one task. The Task Hemispheric Integrity Principle predicts the best dual …

Structural Interference in Dual-Task Performance: Event-Related Potential, Behavioral, and Subjective Effects
… human operator's ability to perform two or more tasks concurrently has led to the proposition that the limited resources available to various information-processing structures are functionally specific and relatively independent. Studies are reviewed which demonstrate that the

Dual-task Performance Involving Grip Force Control in Older Adults with Type 2 Diabetes
… The primary aim of this study was to assess dual-task costs (DTC) in older adults with T2D through tasks involving attention and precision grip force control. The level of attention given to a task may depend on how rested an individual is, and rest is mainly obtained through sleep. Studies …

A Componential Approach to the Investigation of Individual Differences in Time-Sharing (dual-Task Performance, Information Processing)
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 processing ability, (2) an internal model of the system dynamics, (3) maintenance of different operations in working …

The effect of perturbation warning on attention switching abilities during dual-task performance in young and older adults
… switching abilities in older adults during dual-tasking. Fifteen young and 16 older adults performed a tracking task while recovering their balance from a support surface translation. For half of the trials, an auditory warning was presented to inform participants of the upcoming …

The Effects of Fitness Differences and Fitness Training on Dual-Task Performance and the Brain Processes of Older Adults
… trial) on the brain function and cognitive performance of aging humans on a well-characterized dual-task paradigm. Functional magnetic resonance imaging scans were collected on all older adults in a paradigm in which participants were asked to judge both letters and numbers. Consistent with …

The Association Between Musical Training, Bilingualism, and Executive Function
… including working memory, inhibitory control, task switching, and dual task performance. Results for working memory and inhibition are presented in Paper 1 and those for task switching and dual task performance are reported in Paper 2. Both papers are based on the same sample of participants, …

Falls risk and driving performance in older adults
Attention plays an important role in real-world tasks such as driving. Safe driving relies on the ability to allocate attention and perform multiple tasks concurrently. Declines in executive function and dual-task performance have been related to falls in older adults, and recent research suggests …

The Effects of Divided Attention on Speech Motor, Verbal Fluency and Manual Motor Task Performance
Research in dual task performance varies widely in its methodology and results. The present study employed three different types of activity to provide insights into the interference that occurs in dual task performance. Twenty young adults completed a speech task (repeating a sentence), a verbal …

Walking and talking in multiple sclerosis: an investigation of cognitive-motor dual tasking and clinical research portfolio
… the effects of performing a concurrent cognitive task when walking in MS and determine the effects of task demand on dual-task performance. Eighteen MS participants and 18 healthy controls took part. Participants completed walking and cognitive tasks under single and dual task conditions. MS …

Parallel Response Selection in Dual -Tasks
… to do two things at once? Many accounts of dual-task performance have suggested that the answer lies in the concept of a central processing bottleneck---a stage of processing that can only be performed for one task at a time. Using variations of the Psychological Refractory Period (PRP) …

Simultaneous Media Usage: Effects on Attention
… predicts negative consequences in terms of performance cost in learning, and degradation of attention. Related research on dual task performance and multiple-channel processing demonstrates a decline in performance. This study compared sustained attention performance on a cancellation task, …

The Processing of Stimulus Attributes: Evidence for Dual-Task Integrality (Erp, P300, Time Sharing)
Research on dual-task performance has been concerned with delineating the antecedent conditions which lead to dual-task decrements. Capacity models of attention which postulate a hypothetical resource structure underlying performance have been employed as predictive devices. These models predict …

Effects of aerobic fitness on dual task walking in older adults
… aerobic fitness levels leads to better cognitive performance and increases in the oxygenation of the prefrontal cortex (PFC) (i.e., increase in PFC activation patterns). Unfortunately, it is unknown how aerobic fitness levels can affect these measures while dual-task walking. Additionally, the …

The Effects of Task Preference on Speech and Motor Performance Under Divided Attention Conditions
<p>Dual task performance and the interaction of tasks has been the subject of much research. When tasks are performed together they affect each other to varying degrees depending upon such factors as the similarity of the tasks, their difficulty, and whether one task is given preference over …

Reducing distractibility in healthy older adults
In addition to age-related changes in individual sensory systems, older adults also experience changes in how information from multiple sensory modalities is combined. In particular, older adults exhibit increased multisensory integration, showing larger gains than younger adults when information …
