Dual Tasking is beneficial for cognitive health:
Cognitive and Motor Function Enhancement:
Research indicates that engaging in dual-task activities can promote neuroplasticity, the brain's ability to reorganize itself by forming new neural connections. This is crucial for maintaining cognitive reserve, which helps to protect against cognitive decline. A study in the Journal of Alzheimer's Disease in 2016 reported that dual-task training could enhance cognitive reserve and delay the onset of dementia symptoms.

Memory and Attention Improvement:
A study in the Journal of Experimental Psychology in 2013 demonstrated that dual-task training could improve memory and attention. Participants who engaged in dual-task exercises showed better performance in tasks requiring these cognitive functions compared to those who performed single tasks.

Executive Function and Decision Making
Dual-tasking has also been linked to improvements in executive functions, which include skills such as problem-solving, decision-making, and planning. A 2018 study in Neurorehabilitation and Neural Repair found that individuals who participated in dual-task training showed significant improvements in these executive functions.

Physical Activity and Cognitive Benefits:
Combining physical activity with cognitive tasks, such as in exergaming (exercise and gaming), has been shown to have positive effects on cognitive health. A study published in the Journal of Aging and Physical Activity in 2020 found that older adults who engaged in exergaming experienced improvements in both physical fitness and cognitive function.

Dual Tasking and Multitasking are often confused, but they are not the same.
Cognitive Load and Performance:
Salvucci, D. D., & Taatgen, N. A. (2011). The Multitasking Mind. Oxford University Press. This book examines the cognitive processes involved in multitasking and dual tasking, highlighting the different cognitive loads and performance outcomes associated with each.
Differences in Cognitive Processing:
Pashler, H. (1994). Dual-task interference in simple tasks: Data and theory. Psychological Bulletin, 116(2), 220-244. doi:10.1037/0033-2909.116.2.220. This study provides a detailed analysis of dual-task interference and contrasts it with multitasking, showing how cognitive processing differs between the two.
Impact on Cognitive Function:
Just, M. A., & Carpenter, P. A. (1993). The intensity of mental processing: Interactions between the processing of concurrent tasks. Journal of Experimental Psychology: Human Perception and Performance, 19(4), 830-847. doi:10.1037/0096-1523.19.4.830. This research investigates how multitasking and dual tasking impact cognitive function differently, emphasizing the strain on mental resources.
Task-Switching vs. Simultaneous Task Performance:
Monsell, S. (2003). Task switching. Trends in Cognitive Sciences, 7(3), 134-140. doi:10.1016/S1364-6613(03)00028-7. This paper explores the cognitive mechanisms behind task-switching (often involved in multitasking) compared to simultaneous task performance (dual tasking), highlighting the differences in mental demands.
