"People who are heavy media multitaskers may have poorer memory because they have a reduced sustained attention capacity." They do not establish whether media multitasking causes poorer attention or whether persons with poor attention and memory are just more susceptible to digital distractions.
Multitasking is the practice of doing more than one thing at a time. It is essential for people who work in offices or use computers regularly because it allows them to do more than one task at once. However, research has shown that media multitaskers tend to make worse decisions when doing more than one activity at a time. For example, studies have shown that people who text while driving are three times more likely to be involved in an accident than those who don't text while driving.
In addition, media multitaskers remember things less well than individuals who focus on one task at a time. For example, researchers asked participants to complete online surveys on their smartphone daily for two weeks. They found that person-hours of texting and calling per day were correlated with lower scores on measures of verbal memory and visual perception. This suggests that multimedia devices may be distracting enough to impair actual work performance as well as judgment and decision-making abilities.
However, these findings should be interpreted with caution because the study did not control for other factors such as income, education, experience, or mental health issues that could also influence results.
One theory is that intensive media multitaskers have worse working memory because they are more likely to experience attention lapses. However, when task demands are high, such as when working memory activities are more difficult, there is no difference between heavy and light media multitaskers. In fact, heavy media multitaskers perform better on tasks requiring focus and concentration than their medium or low counterparts.
Another theory is that media multitaskers experience a "cognitive load" when trying to remember information from multiple sources. This would explain why they often recall details correctly but cannot be sure of their memory's overall integrity. Cognitive load has been shown to affect memory performance, especially when we try to remember several things at once. Multitasking individuals might simply not have enough room in their brains to store all the information they need.
Yet another theory is that media multitaskers are actually improving their memory skills by testing it out with different types of information. This means that rather than storing few specific facts about certain subjects, they are learning how to organize their minds to help them make connections between pieces of information from different sources. This could also explain why they seem to have such good memories for random events that happen around them every day. They're using their media multitasking to study how things relate to one another and then applying what they've learned to other situations where memory accuracy is needed.
Our minds can only concentrate on one thing at a time. Multitasking affects performance by increasing cognitive load and decreasing attention. However, the negative news concerning multitasking worsens. According to the findings of neuroscientists Loh and Kanai, strong multitaskers have reduced brain density in several crucial areas of the brain. They also have smaller left hippocampus and larger right amygdala compared to non-multitaskers.
Multitasking increases the risk of making mistakes because you cannot focus on multiple tasks at once. This problem is especially apparent when dealing with complex tasks that require different skills or knowledge. In this case, it is best to divide them up into separate sessions so that you do not overload your brain.
Even if multitasking does not affect performance directly, it can still be harmful to your mental health due to the increased level of stress. This becomes even more problematic if you are already prone to anxiety or depression since being under pressure often causes these symptoms to emerge or become worse.
In conclusion, multitasking decreases performance and may damage your brain cells over time. However, there are also positive aspects to this behavior that may help you deal with stressors in your life.
