Second, the nature of the content matters: To date, we have comprehensive research about children and television exposure, if not about interactive screens. However, there are a few things we do know. They also can show that having a video or TV on when a child is doing something else can distract them from play and learning, negatively affecting their development.

Hours of background TV has also been found to reduce child—parent interaction, which has an adverse impact on language development. And this displacement is a big concern: There are only so many hours in a day, and the time spent with screens comes at the expense of other, potentially better, activities. Under-threes, in particular, need a balance of activities, including instructed play, exploring the natural environment, manipulating physical toys and socialising with other children and grown-ups.
The problem is that tablets are extremely appealing to children and adults alike. Thanks to their design, versatility and intuitive interfaces, tablets are a perfect way for children to draw, solve puzzles and be entertained on the move. Because of this, tablets and smartphones make for excellent pacifiers, particularly on long plane journeys and in restaurants. Anecdotally, he and others are starting to see younger and younger patients using these devices compulsively. The rodent family home is a sawdust-filled clear plastic container, one of hundreds stacked up in a rotating system of shelves.
Across the corridor an experiment is underway.
Does spending too much time on smartphones and tablets damage kids’ development? | The Independent
One of the mouse containers is surrounded by bright lights and speakers. For 42 days, six hours every day, baby mice are exposed to the high-octane soundtracks of Cartoon Network shows accompanied by synchronised flashing lights in red, blue and green. The results are startling. The overstimulated mice take more risks and find it harder to learn and stay attentive.

When given the option to dose themselves with cocaine, the overstimulated mice were much more prone to addiction than the control group. The theory is that the same applies to children: Such overstimulation could lead to problems in later life, particularly with focus, memory and impulsivity. Six hours of any activity per day is a huge amount of time, particularly when it involves nocturnal mammals like mice although the researchers say the mice show no signs of stress. Another problematic aspect of screens is that they have been shown to disrupt sleep.
The blue light emitted by the super-sharp displays can interfere with our natural bodily rhythms, preventing melatonin, an important sleep hormone, from being released. This in turn can lead to sleep impairments in adults and children alike. So, she says, they try to use books instead.

In London. Scientists are measuring the electrical activity in his brain as he looks at physical objects and at digital representations of those objects on an iPad screen. Eye-tracking cameras capture the dance of his gaze, and outside the booth research fellow Celeste Chung keeps track of how his eye movements match up with the items on screen.
The team is trying to understand how easily Max, and dozens of other babies like him, can focus attention and block out distractions when working on a particular task. In one of the tests, an object appears at the centre of the screen and then a second object appears, near the edge of the screen, shortly after.
In order to look at the second object, the child needs to disengage from the central one, which requires self-control. But on the effects on language and motor development, he hypothesises that there could be displacement going on. Devices such as iPads may give lots of stimulation, he says, but they lack the nuanced real-time social feedback that helps develop language.
Similarly, tablets and phones may make children dexterous at fine motor control with all the tapping and swiping, but they may have less motivation to get up and explore the world around them. These movements corrupt the brain activity data. Meanwhile, the apps they use may be non-compliant, too. While enhancements might be appear to be engaging children, they could, in fact, be distracting them from the educational content.
Relevant animations, on the other hand, can be beneficial, particularly for children who struggle with language and reading comprehension. Even if apps are found to have educational value, toddlers still learn better from experiences in the real world than they do from equivalent two-dimensional representations on screen. Studies in the US have shown that when dealing with visual—spatial problems, such as finding hidden objects or solving puzzles, toddlers under around 30 months perform much better when the problem is presented in real life rather than on screen.
Children this young are still developing the ability to choose what to pay attention to and what to ignore, and they have trouble generalising from symbolic representations to the real world. Preschool-aged children need to interact with actual physical objects in order to develop their parietal cortex, which controls visual—spatial processing and helps develop maths and science skills in later life. To address this, some app developers are introducing companion toys that can be manipulated by little hands alongside the apps.
Does manipulating a digital object on screen enhance the learning process and make it easier to transfer knowledge into the physical world? And can understanding this mechanism help us develop better digital learning tools? Regardless of our feelings towards tablets and smartphones, these devices are here to stay. So how do we get the most out of them? Thanks to some years of research into how children learn, we can make educated guesses about what sort of interactions, in what sort of circumstances, are best. Devices such as tablets and smartphones can make the most impact in lower-income households.
In these households, people tend to have less access to developmental resources — such as music lessons, extra tuition or just extra hours of social interaction — and so spend more time with digital media. Provided the content is high-quality, tablets and smartphones can have a big impact.
For example, a study from Stanford University in the US found that, by 18 months, toddlers from disadvantaged families are already several months behind their more advantaged peers on language proficiency. With the right content and context, digital devices can help bridge the divide. So instead of criticising devices, perhaps we should be demanding better apps built on solid research. Perhaps what you need now is to take a moment to step away from your problems, rather than allowing your mind to keep circling self-destructively around a whirlpool of negative thoughts.

Have you ever heard of mindfulness meditation? This page has suggestions for youtube guided meditations. If you are at home, take a few minutes to follow one of those guided meditation clips on youtube. Let yourself go and follow the flow of the guide. Take a ten-minute break from your worries. Cut the cycle of negative thoughts for a short while. This is something you can do for yourself right now, and it will give you strength to keep going.
I have a week vacation in 3 weeks coming up. But at rhe same time i have a bunch of things to do before that. I just dont feel motivated anymore. I try to avoid anythinf that remindes me of the lab. I want to cry when i go I have so many projecta and collaborations with them and my onlu intention is to move their projects and help them improve.
But i just cant. I jjst wanna do lab work at home or when im alone. I dont even know what to do at this point. I'm telling you one thing you can do right now. Do one guided meditation. Maybe their 2 one "to ease anxiety, worry, and urgency". Go on--reddit will still be here when you get back. I know this post is a little old now but I recognize enough of my own struggles, mistakes, and literal harmful phrases I've said multiple times that I want to throw in my two cents in hopes that it gives you some more perspective and turn things around.
A lot of what other people have already said is accurate, but I want to address some more of the mental things going on here. I think a lot of "missing part of the story" feelings from people here is really missing the motivations behind actions. This lab is not a good fit for you. It is literally hurting you. You said you aren't a victim because you chose to be there, but those aren't mutually exclusive. Yes, you choose this lab, but now you have more information. Now you can make a better decision based on new data. Also - regardless of victims or whose fault things are, working in this lab is hurting you and you need look for alternatives.
From a once emotionally detached, "self-reliant", independent, "I chose this and everything is fine" person to another - it's not fine. It's not sustainable or healthy. Also see: Have you convinced yourself you enjoy being so busy and exhausted you cannot properly function or relax? You said you're not scared to do work and clearly you aren't because you're overworked. Are you possibly more scared of the alternative?
The world where you don't do everything and aren't in control of everything? A bad habit I had sometimes still have is what I've termed "bulldozing" - basically I would take on everything, do everything, told everyone it was fine I would do it and worked myself into constant mental breakdowns and catastrophic thoughts because I thought I had to do all of the things when no one asked me or expected me to. I genuinely thought I was the only one for every task and job. I never meant to do it or knew I was doing it, but I now understand how bad it was for me and my relationships.
Science is not and will never be a one person endeavor. To continue and succeed in science, you'll have to work with a lot of people. This ties into that whole "you can't actually do everything" idea in 2. Especially because you are dealing with mental illness along with grad school. Be open and honest with them. I know how easy it is to blindly convince yourself you're fine and it's okay - it's not.
If you fall into the "I'm fine" trap around others, bring posts you've written on Reddit as examples of "not fine" so you can remember. Ask them what options they think would help you - group therapy, how often you need appointments, is medication a good option for you, etc. Unfortunately, mental health isn't talked about in a lot of academia and this really screws over the people with mental illnesses.
Talk to other professors and see if you can do short rotations in other labs. Because you'll be talking to your PI's associates, discuss with your PI beforehand that you're interested in getting some more varied experience in other labs. I knew I had found a lab that fit when I kept saying I didn't have a job, "but I go to lab most days", when in fact I was and am getting paid to work in said lab. This sounds like a lame joke someone would make, but I'm serious - I forget going to lab is really my "job" a lot.
Talk to a university advisor and explain to them you aren't happy with your situation to whatever level of detail you are comfortable with. See what they have to say. Their job is to help you figure out what you're doing. They will have suggestions. Sit down and think about whether you really want to work in a lab and be a PI or you just like the idea of it. Why do you love science? What about working in a lab or being a PI inspires you? What do you think a PI does? What are you willing to change about yourself? What will you not budge on? Make sure you keep boundaries you really need to be comfortable and physically and mentally healthy - and then make sure you can achieve those in a science career.
Turn off your brain no brain-related relaxing. Take a weekend day off and literally sleep all day or go on a walk or sit in a bath and listen to music. The world is not going to end if you don't get everything done today or tomorrow. The world is also not going to end if you have to switch labs or even universities before finishing your Masters.
Taking time to relax is important and will help you empty your "stress bar" and refill your mental reserves. I quite seriously refer to these as my stamina and mana bars. I hope thinking about people's advice and especially talking to a therapist helps you start to figure things out. I really feel for your situation. I destroyed a lot of social relationships and wondered why for years. I really thought it was me against the world and I would be fine no matter what terrible things were thrown at me.
In the end, I ran everyone over including myself. It took ghosting on a term, 2 years off of school, and a year and counting of therapy to even get me to see that my own good intentions and independence was what was really wrong. I hope you get to see things clearer sooner than I did.

The rodents were exposed to radiation nine hours a day for two years at a frequency equivalent to second generation cell phones from the s, which is when the study started, The New York Times reports.
Cell phones' potential link to cancer has been an area of study because cell phones emit radiofrequency radiation or radio waves from their antennas, which is a form of electromagnet radiation, according to the National Cancer Institute NCI. The body parts nearest the antenna can absorb this energy, says the NCI, which has created concerns about increased risks of developing cancer and particularly brain cancer.
