COGNITIVE LOAD OF MULTITASKING: HOW CONSTANT TASK-SWITCHING SHAPES ATTENTION SPAN
Abstract
Multitasking has become a normal phenomenon of daily life in the current digital age and is widely regarded as a way to become more productive. However, psychology and neuroscience research show that the constant alternation of the tasks imposes a lot of cognitive load that can adversely influence the capacity to sustain attention and overall performance. The current review presents an investigation in the relation to the multitasking, cognitive load and attention regulation and how more frequent the changes in tasks could be associated with short and long-lasting cognitive performance. It is shown that multitasking can create an illusion of productivity yet it places an enormous burden on working memory, reduces the efficiency in the processing process and predisposes errors, as well. Short-term effects will include disjointed attention, impaired task performance and information loss. Long-term multitasking has been linked to the declining sustained attention, growing mental fatigue, and failure to selectively perform tasks under long-term conditions. The overall implications of the findings to education, productivity, and mental health in the workplace are also demonstrated in the review. Multitasking was also observed to have negative implications on learning performance and deep learning in an academic context and impaired performance and accuracy in a work context. The constant pressure on the attentional resources causing stress, falling self-regulation, and potential long-term losses of attention also play a psychological role in the strain. The new approaches such as mindfulness training, digital well-being interventions, and appropriate task management practices are offered as the means of changing the problem of cognitive overload. To bring the discussion to a close, it is important to note that, as much as multitasking might seem adaptive in the fast-paced setting, there are negative impacts of multitasking on attention span and this begs the question of balanced task engagement. The identification of these mechanisms would help individuals and organizations to become more effective and healthier in their cognitive practices.
