2 for many of us multitasking has become routine, but does performing several task at the same time. really make sense? once again, it's me. our brain is not good at tackling to different tasks, simile tediously. it causes stress that can be measured a business. we know that stress can damage various areas of the brain shading. so what does multi tasking actually do to us? look at different magic power of multitasking is to create the subjective illusion that we are achieving a great deal to see the slides to talk. it's a feeling nourished 1st and foremost by the digital world. seductive yet demanding . it keeps as constantly on the go. neil to duty, gallium, he felt good of little papa because we're always in reception mode for everything. actual attention span is reduced. we need to actually show today it is considered quite normal to be constantly accessible while performing some other task. but sometimes multitasking is also productive, it's about finding the right degree in structure towards. but where is the limit power as our brain react when it has to perform different tasks simultaneously. and what about the body? are there also positive effects perhaps? and is it true that some people handle multi tasking better than others? ah ah, we humans are quite capable of doing different things at the same time. but that depends on the tasks and the conditions. during the pandemic, many parents were forced to juggle child care and working from home by ah, but is this what we mean by multitasking? ah young, i'm more to tossing reverted to my guns and multitasking is not always used in one rigid sense to some, it really does mean doing 2 things at the same time. others seem multitasking as coordinating to different life roles like being a parent and having a job in the term. multi tasking actually comes from computing. it describes the ability of an operating system to perform several tasks simultaneously. the human brain is also a gigantic complex computing center, but it's no computer machines function solely along mathematical lines. they are characterized by their ability to process and store vast amounts of data very quickly. by comparison, our brain works in a selective way, constantly absorbing information, even when we're not aware of it. not really slow, he most processes, of course, take place subconsciously. that simply depends on how many processes are automated . yeah. it's been easier for them to take place parallel to others, but our capacity for solving problems that involve new and in particular, more complex mental performances is very limited, yet are capacity to say because the constant filtering and selection of incoming information is carried out by the thalamus in the inter brain, the main switching center for the sensory organs, the thalamus, passes relevant information on to the cerebral cortex. everything we see here feel taste or smell is processed in the cerebral cortex, which is also responsible for what we think, learn and memorize. it is the interior singular cortex, or the a c c, which controls our conscious focus. ramsey's on dr. garcia said she'd in the outcomes for instance, we have to perform 3 different tasks and manage to do so successfully. elsco. this is only because we focus on task number one, was suppressing the challenge posed by tasks 2 and 3, not uniform cover eyes on don't look and i switched to task. number 2, i wonder, are we suppressed the challenge posed by tasks one and 3 lines on barnes, alberto, and we need a strength for this on the craft shoot calls for great attention and above all, self discipline therapist is typically in many situations. we overestimate our capacities and as a result, even put ourselves in danger. driving is still a highly complex activity even for experienced motorists. using your smartphone while at the wheel is illegal for good reason. tests carried out in germany and the united states have shown that the attention of a motorist using a mobile phone is reduced by 40 percent. that's like having a blood alcohol level of between 0.8 and 1 point one per mill. with our subject, an experienced motorist wants to find out for herself and has turned up for some driver safety training. she has to cover a certain distance over which she will face various challenges from time to time. she has to read and write messages on her smartphone or make a call. just like in real life are motorist is well aware that she is in a special test situation and that her attention is being divided. nevertheless. some one losing concentration for just 2 seconds at 50 kilometers an hour drives blindly for nearly 30 meter. ah oh. here too. it's a case of distraction through parallel digital communication. in this college seminar, the lecturer is constantly competing with the entire online world. yet, studies carried out at 5 german universities, showed that the performance of students using smartphones during a lecture drops by about 30 percent ah, of for you. okay, and what about you, or do you divide your attention? how many platforms can you handle simultaneously without having the feeling that it's just too much murphy's? but i've noticed that for instance, i can't discuss something with my mother while tie my shoe laces. i admit that i just can't do it, get the hook up. so when you get this hazel checked off, can i was in love stopped phenomena. i've got one device f as in and i usually have an i pad, making notes or whatever. i might also have instagram on my phone, but then when i get a message, i noticed that i'm no longer concentrating on the lecture and need to refocus of the house. so i'm not really good at multitasking where to test can finish the clock. mr. hood. all of them to law from time to time. i listen to spotify, i don't have it on loud. just in the background following the lecture is no problem . psychologist said, zurich university have been studying exactly what happens in the human brain when it is confronted simultaneously with learning material and music. after all, many people listen to music while they are working. they think it helps them concentrate better. some learning theories even support this idea. oh, in the zurich experiment, subjects learned sometimes with and sometimes without music. here for example, a student is learning english vocabulary, while listening to classical music for brain activity is being recorded. mathias koby, the ph. d student who is running the experiment keeps a close eye on the e g curves. together with the head of the study professor litzy anchor, the young scientist is monitoring how the woman's brain is coping with dual task siblings. although he is actually a great lover of music, professor yankee would never listen to music while working. and he has his reasons for the brush, which was a latin and will cause your learning vocabulary. for example, was while listening to music, i should really be focusing solely on learning vocabulary and suppressing whatever music triggers in your brain flu fighting it in a way that came from that costs strength and effort craft. or we're come to do it for very long. l u r. o. in the laboratory, professor yankee has shown visibly how a composition by the vanity trigger is virtual storm waves in the brain. this leaves little room for coping with additional tasks and other stimuli as get kovasos ma'am. then there are certain exceptions. when you work in an open plan office and are surrounded by stimuli, alpha one who and that might put on headphones and listen to predictable music launch like lounge music for relatively simple music. which to a certain extent has a predictable structure. but that is the lesser evil compared to constantly changing upon expected stimuli on the heights. it all depends on how strongly our attention is challenged. consumers can observation and us pause aquanda offices in. so if we calculate fairly accurately, that's 11000000 bits of information impact on her census every 2nd time process. but we can only consciously process between 11 and 60 bits of it if be so just think about that for a moment. 11000000 bits vs between 11 and 60 bits zorn bits vessels. so we have to consciously select this consciously processed in recent mission viejo. valan looseness also. but how do we do that? in a soundproof chamber at the likeness research center for working environment endorsement, professor edmond venture and his team are studying how our speech comprehension functions. this particular experiment focuses on the cocktail party effect. it involves the situation in which just like at a cocktail party, we are surrounded by lots of sensory stimuli. here. 3 people can be heard at once. so how does our brain sort this battle of voices? does the specially recent call to a certain extent? it's like a filter, but one that is always based on mutual interference. in other words, on competition between the various types of information or the neurons which process certain types of information. i. in this experiment, the research team endorsement want to determine the importance of additional visual information like mouth movements for speech comprehension. this research is becoming increasingly important, especially for our working lives. as they, if they can be no doubt that through the new technologies and also through digitization in many areas, we have to process far more information than in the past many more jobs these days involve information processing might split. so a challenge exists today that cannot be compared with what we had 20 or 30 years ago. nice for christ. first, from the most useful transmittal closure, morgan job offers often stressed the need for applicants to be capable of multitasking. so does this mean that any one applying must be able to handle as many things as possible at once without being deterred by interruptions? yeah. okay. well, the marble good along with it seems the ideal efficient employee is now considered someone who can communicate easily with colleagues, customers, and bosses who is always available and accessible and who can work on several digital devices at once. while keeping track of all their tasks the phenomenon of multitasking is not only found in an office environment, but also in the production sector. the change in the world of work has also changed research into the working environment. in the past, such research tended to focus on physical demands. today, the emphasis is mainly on mental pressures. to what extent does our head play along when, for instance, it has to process information while completing a physical task. in this boating experiment, subjects have to negotiate obstacles without losing their balance on the swaying deck, a mental, but also motor challenge ah, the altar, modern gait laboratory, allows for tests and extreme situations without the risk. as about what's wrong to focus in the boating experiment is mainly on physical coordination on stability, and also and move. i am planning to reagan them. the next experiment also calls for maximum concentration. this time the subject has to cross a suspension bridge. what is simulated here in a virtual environment provides important information for structuring our world of work more on buffet, co, just think of a roofer or in a different context of people working in logistics, who have to process various forms of information but who have to do so while moving in certain industrial contexts, there is increasing use of data glasses. information is presented directly in the glasses. so it is only presents for the size, and that is the situation we know too little about in order to safe a certain, not only that safety is guaranteed your in walking. but also that all information can be processed correctly with the money from which inside the modern workplace. the interface between people and technology is becoming increasingly important. a fairly new area of research known as cognitive narrow ergo, nomics focuses mainly on studying the new mental demands at the workplace. ah, how do we cope with the many challenges? what is the advantage of working on several things at once? does it really make us faster and more effective, or conversely, is multitasking counter productive? ha. oh doctors and especially nursing staff, often deal with multiple demands and work interruptions, constantly switching between carrying directly for patients, administer of tasks and organizing a hospital ward. this stressful scientists have been taking a closer look at the everyday routine in hospitals and amongst other things we have carried out, studies evolving care is on an early shift, who, depending on whatever task they are performing are interrupted between 60 and a 120 times if preparing medication, for example, this could result in disastrous mistakes being made. feelin cold working in an emergency center like the trauma hospital, berlin requires not only a practiced routine, but also a high degree of flexibility. according to dr. johan allude, big outsiders often have no idea what this entails of seat mankato dish, baffled at seriously. injured cases are rarely seen in a waiting room. they come in through different entrance, not taken straight to a shock room. they require a large number of staff and a lot of time. and naturally they take priority of everything else. but people in the waiting room find it hard to understand why they are having to wait so long. with apparently nothing happening. they often think that instead of walking doctors, the nurses are sitting around drinking coffee. when fact they are perhaps in the shock room saving someone's life. urgency is determined on the basis of an initial medical assessment. the triage system lays down clear criteria. colors illustrate the time windows involved. read means the patient needs immediate treatment. orange means that doctors have 10 minutes to spare. green and blue represent the less serious cases. but not all procedures are predictable. that's where flexibility comes in. minus lessons who possessed him, triology is an excellent system. but in my opinion, teamwork and cooperation are at least as important. so if a nurse has been working in the emergency center for seniors comes to me and says, for you, hanna, i'm worried about a patient. you need to take a look another i go and check even if the patient has been trashed, green and i would actually have an hour's time to spare, infecting from that side. her as a rule, seriously injured patients are announced 10 minutes in advance. so the hospital team is already waiting, despite the time pressure here, there is no hectic activity. the calm and focused hand over the patient is an important point in the process is a 2nd to 3rd degree burns covering 15 percent of the body sustained this morning. and caused through using a fire accelerant i mean, what for a minute we don't look at the patient will talk to him or her. and we just listen to what happened last estie. it's a totally structured procedure talked or to clay. sorry. how did it happen? procedure that's especially important and trauma saturated caught and i would want to sort of forces were involved what kind of an accident, patton, no, talking about on what has been done already. and he then is the patient transferred and treatment commenced to the hospital where multitasking is concerned, optimum work flows and clear communication are of major importance. scientists that cobblins university are studying how that takes place in a totally different environment. large commercial enterprises. as of a tweet, business management, it is always said that there is too much multitasking and we definitely see that in companies to basically the problem has been recognized, but it is hard to remedy. oh, the big question is how to maintain an overall view of the diverse existing and incoming tasks leaves them. it is assigned to least one on that as i do here. incoming and completed tasks are represented in totally analogous fashion with stickers. what at 1st glance, seen somewhat out of date in our digital world, is in fact totally appropriate. the obstruct dog, the all comes to loans, and she complexities in di, digital. the more abstract task saw the more complex and the more digital they are . the more important it is for us to break things down and depict them to see if 10 machines are half finished in a factory. see being physical entities. they are much easier for someone to see than 10 customer inquiries which have all been embarked on to some degree. but without clients having seen any results. in almost no model factory here at copeland university, we made the processes in a fictional truck plant visible and really comprehensible it starts with purchase with procurement capital. so here at the back we have the suppliers. then we have the receiving area, then warehousing on this is the intro logistic sector with various production stations and finally dispatch. so the aim here to is to identify uncontrolled negative multitasking and to find ways of doing things better. mom to fin beam on the spectrum. ok, and that is necessary in many areas in a major study involving participants from both trade and industry. professor commerce and the vista consultancy found that 20 percent of capacity is wasted and 25 percent of turnover is lost through permanent multitasking in project management . lou, this vicious, almost important discovery was that the situation really is as bad as is always claimed before. there is a lack of clear structures, clear objectives to prioritization is not very clearly defined. so we have to assume that there really is too much multitasking in many areas of companies and organizations that above all. hm. there is no structure or no system for addressing this problem to few multitasking between finally misty. it kind of shook 2 kinds of steam beam under socket. one of the participants in the study was swiss company interests, and houser, one of the world's leading providers of process and laboratory technology. the company develops highly specialized measuring devices. and recently, with the push for automation, digitization and sustainability demands on the company, whoever is an enormously robert will decide over time. we have found that all door staff are working more and more being exposed to increasing stress. the final analysis less is being achieved and the reason we wanted to make use of the latest scientific findings in order to improve the situation home. this is true, it's wonderful person ah, the study involved online surveys and extensive interviews with workers and management in order to examine the work process from various angles. the major question, at what point in the process do multiple stresses occur as i'll probably in lockley filled and indeed the main problem was that the people doing the work. in this case, the development teams simply had to handle too many tasks from a y range of areas soon to system. and that every task had top priorities. plato of marvel hoops the situation results in overload in a team. so i know you've all lost inventive. consequently, separate work areas were created within the open plan office. now the software developers can work with fewer disturbances and coordinate better with one another . the company restructured workloads and got rid of the 14 day phases known as sprints. now, management clients and staff together determine realistic targets, individual workloads, and prioritize tasks. the result is a transparent and connected workplace with both and how much sugar and efficiency is concerned. i'd say that we have improved by a factor of 3 to 4. it was few proposal coordination within the team and being able to work undisturbed is distressing for everyone. in general, being completely immersed in a hobby or task has a positive effect on our sense of success and our feeling of happiness. this is called the flow experience.
