Summary: This study investigated the effects of age on postural performance and postural control strategies. The results showed that older individuals had larger postural sway displacement compared to younger individuals when sensory input was suddenly removed or added. Additionally, the dual-task paradigm influenced the control strategies of middle-aged and elderly adults.

Summary: This study found that performing dual tasks with a mobile device can significantly affect gait parameters, especially in older adults. Compared to traditional dual-tasking, using a smartphone produces more significant results. These findings contribute to improving early diagnosis of mild cognitive impairment.

Summary: Dual tasking leads to the deterioration of postural control in individuals with schizophrenia. Specifically, cognitive tasks alter postural control in the absence of visual information, indicating possible sensorimotor dysfunction in this population.

Summary: Dual-tasking can lead to cognitive-motor interference (CMI) and impact task performance. This study examined the effects of age, gait speed, and cognitive task type on CMI during walking. The results showed that slow walking, older age, and tasks involving working memory, language, and problem-solving had the highest levels of CMI.

Summary: This study investigates the relationship between conflicting response codes and interference in dual-tasking, with a focus on the effects of age. Using fMRI, the study examines the brain activity correlates of response-code conflicts, as well as activity modulations by individual dual-task performance and cognitive abilities. The results show that resolving dual-task response-code conflict recruits substantial parts of the multiple-demand network, but this activity is not significantly affected by individual differences in task performance or age.

Summary: This study investigated the improvement in dual-task performance after cognitive training and physical activity, and found that different components of the task were improved by different training methods, suggesting the involvement of different mechanisms.

Summary: Studies on age-related positivity effects during facial emotion processing have shown contradictory results. This study aimed to clarify the mechanisms of cognitive control during emotional face attention among older adults, finding that older adults performed better on fear trials compared to younger adults. Furthermore, asymmetrical brain activity in the two hemispheres of older adults was observed, suggesting potential implications for normal aging.

Summary: The study utilized a dual-task paradigm to investigate the effects of attentional control on gait and inter-joint coordination, revealing significant differences in performance between the High Attentional Control (HAC) group and the Low Attentional Control (LAC) group. This suggests that the ability of young adults to maintain gait control and modulate inter-joint coordination patterns in response to gait disturbances is influenced by their level of attentional control.

Summary: Driving is a complex activity that requires the coordination of motor behavior and cognitive information processing. Dual-tasking, especially when the subtasks require similar neural resources, can lead to performance decrements. This study examined the neural correlates of dual-task driving in different age groups and found that older adults experienced a greater decrease in steering precision when combining a visuomotor dual-task. Additionally, the increase in mid-frontal theta power, indicating the recruitment of mental resources, was less prominent in middle-aged and older adults, which may suggest a plateau effect in mental resource saturation.

Summary: The study showed that younger adults had faster reaction time compared to older adults during dual tasking, and both males and females had slower reaction time for the Working Memory test when seated. Older adults exhibited greater stride length variability during the Working Memory task, and overall, dual task cost for gait was higher than for cognition regardless of age or sex.

Summary: There is a critical need for human involvement in multi-robot systems (MRS) to successfully perform their missions in real-world applications. While the hand-controller is commonly used for MRS control commands, it is inadequate for scenarios involving concurrent MRS control and system monitoring tasks. In our study, we propose a multimodal interface that extends the hand-controller with a hands-free input based on gaze and brain-computer interface (BCI), showing improved performance and reduced workload for operators in dual-tasking scenarios.

Summary: The study reveals that interference between motor responses contributes to dual-task costs, supporting the motor-bottleneck hypothesis. In contrast to the response-monitoring hypothesis, experimental evidence shows that Task-1 motor processing significantly lengthens RT2, indicating response-related interference.

Summary: Bilateral vestibulopathy (BV) is a chronic vestibular disorder that affects cognitive and motor performance. This study found that patients with BV had poorer performance in mental rotation, visual and auditory working memory, and experienced greater cognitive-motor interference in dual-task conditions.
