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
… determine whether a complex cognitive and motor task (memory search and tracking combination) showed a performance deterioration under the influence of two antihistamines (benadry| and hismanal) and to determine if the chosen task was of sufficient sensitivity to register decrements in …

Human information processing efficiency in a dual-task paradigm
… Regan, and Lee (1989) have presented a dual-task paradigm which they claim enabl JS a strict test of the single-channel hypothesis. In this paradigm, subjects perform two serial choice reaction time (RT) tasks, first separately, and then simultaneously, at their maximum sustainable rates …

Let's get physical: the dual-task costs of multiple motor responses
Dual-task costs occur when attention is divided among two or more concurrent tasks. Most dual-task studies involve paradigms where participants complete two, concurrent cognitive tasks; in these studies, performance on one or both tasks are slower and/or less accurate. The goal of this study was to …

Dual-task interference and its influence on deception detection and memory
Using a dual-task paradigm, I examined how engaging in executive function tasks impacted deception detection and memory performance. University students (N = 185) were randomly assigned to detect deception while also performing a concurrent monitoring, memory, planning, motor, or visual task, or no …

The Attentional Demands of Positive Reappraisal in a Dual Task Paradigm
… before an emotion fully develops, individuals have the potential to alter the extent to which they feel certain emotions. This strategy has been associated with a wide array of beneficial health and psychological outcomes, and is also used in treating different forms of psychopathology. …

The Effects of Fatigue on a Dual-Task Postural Control Measure
… current approach to assessments among each individual evaluation involved; however, the combination of all three assessments adds to its strength and determining the overall understanding of the concussion and its effects. Any measure of assessment that connects underlying issues arising from …

Effects of aerobic fitness on dual task walking in older adults
… fitness levels can affect these measures while dual-task walking. Additionally, the relationship between aerobic fitness levels and cognitive motor interference (CMI), which is a direct of measure of dual-task performance related to falls in older adults, has not been examined. It is important …

The Spillover Effects of Motivational Processes in a Dual Task Setting
… discrepancy (GPD) feedback for one task could have a negative effect on goal-setting associated with an unrelated, distinct task. A series of hierarchical regression analyses were conducted. Results show that large versus small negative GPD feedback on a creativity task impacted …

Improving community walking after stroke; the effect of dual task treadmill training on gait, cognition and brain control mechanisms of dual task walking in chronic stroke survivors
… still impaired. This thesis set out to explore dual task ability after stroke in relation to community walking and explored dual task treadmill training in stroke survivors. In addition, functional magnetic resonance imaging (fMRI) and functional near-infrared spectroscopy (fNIRS) in stroke …

Hemispheric Effects of Verbal Information Processing on Single and Dual Task Performance
… 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 task performance will be found when …

Head Position Variability During Single and Dual-task Tandem Gait Concussion Testing Protocol
… neutral and cervical flexion during single and dual-task tandem gait. METHODS: 25 apparently healthy subjects (age=21.9±1.41 years) performed tandem gait walking along a 3-meter piece of tape affixed to an instrumented walkway (30 Hz, Tekscan Strideway, Tekscan Inc., South Boston, MA). Each …

Training-Induced Changes in Dual -Task fMRI Activation in Young and Old Adults
… correlates of training-related improvements in dual-task processing in older and younger adults. The first study consisted of untrained younger adults with the goal to discriminate between cortical regions involved in preparing to make more than one response from those involved in the management …

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 …

The Effectiveness of a Dual Task Concussion Assessment for Identifying Impairments in Concussed Athletes
<p><strong>Context: </strong>Commonly used single task (ST) concussion assessments are unable to identify lingering impairments following a concussion. Current dual task (DT) assessments use cost prohibitive technological assessments not available to most clinicians, creating the need for a …

The effects of transcranial direct current stimulation on dual-task walking in Parkinson's disease
… If eligible, participants will undergo a dual task assessment and a freezing of gait (FOG) provoking protocol prior to, as well as immediately after, a 20-minute session of tDCS. The acute effects of each stimulation session will be observed. There will be three different stimulation …

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 …
