Objective: Many studies have suggested that there is a relationship between coherence and cognitive processes. This study aims at investigating this hypothesis through assessing the relationship between cognitive variables and coherence in the discourse of two groups of Persian-speaking younger and older adults. Methods: In order to evaluate our participants' cognitive capabilities, we recrui...

Although functional imaging studies have frequently examined age-related changes in neural recruitment during cognitive tasks, much less is known about such changes during motor performance. In the present study, we used functional magnetic resonance imaging to investigate age-related changes in cyclical hand and/or foot movements across different degrees of complexity. Right-handed volunteers ...

The cerebellar dentate nucleus has been reported to project to motor and prefrontal cortical regions in nonhuman primates from 2 anatomically distinct areas. However, despite a wealth of human neuroimaging data implicating the cerebellum in motor and cognitive behaviors, evidence of dissociable motor and cognitive networks comprising the human dentate is lacking. To investigate the existence of...

This case series explored the feasibility and efficacy of cognitive-motor dual-task gait training in community-dwelling adults within 12 months of stroke. A secondary aim was to assess transfer of training to different dual-task combinations. Seven male participants within 12 months of stroke participated in 12 sessions of dual-task gait training. We examined single and dual-task performance in...

Task prioritization can lead to trade-off patterns in dual-task situations. The authors compared dual-task performances in 9- and 11-year-old children and young adults performing a cognitive task and a motor task concurrently. The motor task required balancing on an ankle-disc board. Two cognitive tasks measured working memory and episodic memory at difficulty levels individually adjusted durin...

Children with attention-deficit hyperactivity disorder (ADHD) commonly experience issues with both cognitive and motor abilities. This study aimed to determine whether a correlation exists between these 2 domains in children with ADHD. Tasks assessing executive function and motor performance were carried out with a sample of 50 children. The data demonstrated significant correlations between pe...

Many daily activities require performing multiple tasks and involve the integration of cognitive motor skills, on which outcome depends. studies approach influence gait postural control, but few analyze effect another task during or control. This review aims to used in dual-tasks classify as their difficulty level. The literature was conducted according PRISMA guidelines databases: Medline, Web...

Persons are often engaged in activities that combine multiple tasks (so called multitasking), even though this combination is typically accompanied by performance costs in the individual tasks in comparison to their performance as single tasks. Such performance costs suggest that performing multiple tasks brings the cognitive processing system to its limits. However, the observed limitations ca...

depression disorders are associated with serious dysfunction and depressive symptoms. cognitive slowing is a clear symptom observed in all depressed people. pvsat is a measure of cognitive function that specifically assesses visual information processing speed and flexibility, as well as calculation ability. the aim of the present study was to determine whether the paced visual serial addition ...

conclusions this persian version of the fim can be used as a valid, reliable, and replicable instrument for research and rehabilitation purposes in tbi patients. results the inter-rater reliability was acceptable on admission and at discharge (icc = 0.779 to 0.895). the internal consistency of fim and its subscales were excellent (α ≥ 0.97). the results for criterion validity by adjusting the v...
