Generalized slowing characterizes aging and there is some evidence to suggest that this slowing already starts at midlife. This study aims to assess reaction time changes while performing a concurrent low-force and high-force motor task in young and middle-aged subjects. The high-force motor task is designed to induce muscle fatigue and thereby progressively increase the attentional demands. Tw...

Objective: The present study was aimed to correlate the clinical tests with the laboratory measures under dual task conditions in Parkinson's disease (PD). Materials and Methods: Eleven people with idiopathic PD (Modified Hoehn and Yahr scores 1-3) were selected by simple non-probability sampling. Center of pressure (COP) data obtained by force platform was used to calculate mean total velocity...

Theory suggests that driving should be impaired for any motorist who is concurrently talking on a cell phone. But is everybody impaired by this dual-task combination? We tested 200 participants in a high-fidelity driving simulator in both single- and dual-task conditions. The dual task involved driving while performing a demanding auditory version of the operation span (OSPAN) task. Whereas the...

The aim of this study was to determine the effects of motor practice on cognitive and motor performance in older adults under single- and dual-task conditions. Fourteen younger (19-28 years) and 12 older adults (67-75 years) performed a precision grip sine wave force-tracking and a working memory task under single- and dual-task conditions. Participants performed a pretest, 100 motor practice t...

OBJECTIVE: Dual-task is the ability to simultaneously perform two motor, behavioral, or cognitive tasks with different objectives at same time. Most of daily life activities consist dual-tasks. training commonly used in physiotherapy and rehabilitation. This study aimed conduct a bibliometric analysis dual-task studies rehabilitation describe their progress trends. MATERIAL AND METHODS: Data fo...

The relevance of dual-task walking to everyday ambulation is widely acknowledged, and numerous studies have demonstrated that dual-task interference can significantly impact recovery of functional walking in people with neurological disorders. The magnitude and direction of dual-task interference is influenced by the interaction between the two tasks, including how individuals spontaneously pri...

The effect of a working memory demanding dual task on perceptual category learning was investigated. In Experiment 1, participants learned unidimensional rule-based or information-integration category structures. In Experiment 2, participants learned a conjunctive rule-based category structure. In Experiment 1, unidimensional rule-based category learning was disrupted more by the dual working m...

A previous dual-task study (Capizzi, Sanabria, & Correa, 2012) showed that temporal orienting of attention was disrupted by performing a concurrent working memory task, while sequential effects were preserved. Here, we recorded event related potentials (ERPs) during single- and dual-task performance to investigate how this behavioural dissociation would be expressed in neural activity measures....
