New Studies Uncover How Multitasking May Affect Your Productivity
Multitasking is often seen as a key skill in today’s workplace, but recent peer-reviewed studies are challenging this assumption. New scientific research examines how frequently switching between tasks may impact productivity, cognitive abilities, and emotional well-being. Here, we present a summary of recent findings, as reported by the authors of several major studies.

What Recent Research Reveals About Multitasking
Study Background and Purpose
A 2022 study led by Professor Anthony Sali at Wake Forest University investigated the neurophysiological aspects of multitasking. The authors explain that what is commonly described as multitasking is actually rapid switching of attention from one task to another, rather than performing multiple tasks simultaneously. The study reports that brain activity measured by fMRI and EEG demonstrates a “switch cost” each time attention is redirected. (Sali et al., 2022)
A report from the American Psychological Association (APA, 2023) also examined perceptions of multitasking and cognitive performance among adults in various professional settings. According to the APA, more than half of respondents believed that multitasking negatively affected their cognitive abilities and information retention.
Researchers at the University of Houston explored the emotional consequences of frequent task-switching in the workplace, focusing on stress and job satisfaction.
Methods and Study Design
The referenced studies used neuroimaging techniques such as fMRI and EEG to assess brain activity during rapid task-switching. Large-scale surveys by the APA and Harvard Business Review included adult employees aged 25–55 from a variety of professional backgrounds.
Key Findings from the Authors
- The Brain’s True Response to Multitasking
The Wake Forest University study concludes that so-called multitasking is actually frequent task-switching, which imposes a measurable cognitive cost. - Task-Switching and Productivity
The researchers found that the “switch cost” was particularly noticeable when participants performed complex tasks or those requiring sustained attention. - Cognitive Impacts
The APA survey found that 55% of respondents reported impaired cognitive performance and memory retention when frequently switching between tasks. - Emotional Consequences
According to the University of Houston study, the continuous demand to switch between tasks was associated with increased feelings of stress and frustration. - Possible Effects on Job Satisfaction
The same team observed that negative emotions related to frequent task-switching could lower job satisfaction and contribute to long-term fatigue.
Authors’ Interpretation and Context
The authors of these studies emphasize that the cognitive and emotional costs associated with multitasking may be significant in real-world work environments. Sali et al. (2022) suggest that while multitasking is common, it is associated with measurable declines in cognitive performance, especially for complex tasks. The University of Houston researchers indicate that frequent multitasking may raise the risk of burnout and employee turnover over time. The studies also note that these findings are based on laboratory and survey data, and that further longitudinal and cross-cultural research is needed.
Conclusion
Peer-reviewed scientific studies published in recent years indicate that multitasking is associated with a measurable “switch cost” and may lead to reduced cognitive performance and increased emotional stress, according to the study authors. The researchers suggest that greater attention should be paid to the consequences of frequent task-switching in the workplace.
