Being constantly connected online has bad consequences: harming memory, make you stupid

How much is too much?: Studies have found that Internet is harming our memory, especially short-term or working memory

How Smart Phones Make You Stupid - Consumer Association of Penang (CAP)



Being constantly connected to the digital world has its consequences - setting the rules with social media

In order to have a more harmonious marriage, H and I have decided that we need some rules.

Recently, we came up with Rule No. 1: You can only repeat something once.

It’s been really helpful in keeping the nagging level of our marriage down. In the past, we would nag at each other quite a bit.

It has worked so well, we thought we should introduce more rules.

A few weeks back, he suggested Rule No. 2: No Googling and checking of e-mail at the dining table and just before we sleep.

I baulked.

What a ridiculous rule, I said. It’ll be impossible for me to agree to it and it’s not fair because it’s targeted at me.

How can I not be checking my e-mail all the time, I continued. I am a journalist. I must know what’s happening and I must be contactable 24/7. What if a story breaks? I need to know at once. I was, of course, exaggerating my own importance.

The world and the newsroom chug along just fine whether or not I am online. My bosses don’t expect me to be constantly connected (I think).

I was using work as an excuse. An excuse for an affliction I am finally coming around to acknowledging, but which H has noticed for some time: I have an addiction.

I have an addiction to Googling, to my smartphone, to my iPad, to being connected to the digital world.

My phone follows me everywhere I go. I sleep with it inches away from my pillow and my nights (as well as his) are punctuated with beeps, blips and pings from the many message notifications streaming in.

I check my phone goodness knows how many times a day, to look at my e-mail, WhatsApp, Telegram, Twitter, Facebook, Vine, Instagram and a few other apps.

When I’m at the cinema, I’m one of those irritating people whose phone screen lights up during a movie because I’m checking it.

I literally break out in a cold sweat when I misplace my phone.

At home, I walk around not only with my phone, but also my tablet.

I am addicted to Googling on my iPad. I can spend an entire day in bed just Googling (oh, bliss). Sometimes, when the Wi-Fi speed is acting up, I Google on both my phone and tablet at the same time, just in case one gets to the information I want quicker.

“You’re addicted,” H says.

“I’m not,” I say. “It’s my job. I am not addicted. I know when to stop.”

To prove my point, I went onto Google (of course) to try out some are-you-an-Internet-addict tests.

The most helpful article I came across was in Yahoo by Dr James Roberts, a professor of marketing at Baylor University in Texas in the United States.

He explained that anything that can produce pleasure in our brain has the potential of becoming addictive and what makes something an addiction is when we lose control.

Research, he said, has identified “six signs” of any type of substance or behavioural addiction.

These signs relate to issues connected to salience, mood modification, tolerance, withdrawal, conflict and relapse. I have a problem. But the situation isn’t that dire, I’d like to think.

Still, I shouldn’t be complacent. It can’t be pleasant living with someone who doesn’t give you her full attention because her nose is always stuck in a screen. It is also rude.

At work, I have got into the bad habit of not looking at colleagues I’m talking to because I’m also typing away on my phone or computer.

At meetings when I’m just the slightest bit bored, I find it hard to resist reaching for my phone and checking my e-mail, which is impolite to the person who’s speaking.

My attachment to my devices can be dangerous – I walk and text a lot. The intense and constant staring at screens is causing eye strain.

Studies have also found that the Internet is harming our memory, especially short-term or working memory.

Information overload and distractions – hallmarks of Internet surfing – make it harder to retain information in our brains.

When we know a digital device holds information for us, we are also less likely to remember it ourselves. It has been years since I memorised anyone’s telephone number. I’m not even sure I can do it now.

Having so much information at my fingertips has made my brain lazy and mushy.Google makes you feel clever when you really aren’t.

Also, while social media like Facebook have been praised for bringing people closer, they can in fact isolate us when we use them in place of face-to-face interactions.

As for H and me, I think I should agree to some version of Rule No. 2 if I want a happier marriage.

Totally no Googling and checking of e-mail at the dining table and just before we sleep might not be doable.

But I can live with “less” Googling and checking of e-mail. One step at a time

Memory Strengthened by Stimulating Key Site in Brain

ScienceDaily (Feb. 8, 2012) — Ever gone to the movies and forgotten where you parked the car? New UCLA research may one day help you improve your memory.

UCLA neuroscientists have demonstrated that they can strengthen memory in human patients by stimulating a critical junction in the brain. Published in the Feb. 9 edition of the New England Journal of Medicine, the finding could lead to a new method for boosting memory in patients with early Alzheimer's disease.

The UCLA team focused on a brain site called the entorhinal cortex. Considered the doorway to the hippocampus, which helps form and store memories, the entorhinal cortex plays a crucial role in transforming daily experience into lasting memories.

"The entorhinal cortex is the golden gate to the brain's memory mainframe," explained senior author Dr. Itzhak Fried, professor of neurosurgery at the David Geffen School of Medicine at UCLA. "Every visual and sensory experience that we eventually commit to memory funnels through that doorway to the hippocampus. Our brain cells must send signals through this hub in order to form memories that we can later consciously recall."

Fried and his colleagues followed seven epilepsy patients who already had electrodes implanted in their brains to pinpoint the origin of their seizures. The researchers monitored the electrodes to record neuron activity as memories were being formed.



Using a video game featuring a taxi cab, virtual passengers and a cyber city, the researchers tested whether deep-brain stimulation of the entorhinal cortex or the hippocampus altered recall. Patients played the role of cab drivers who picked up passengers and traveled across town to deliver them to one of six requested shops.

"When we stimulated the nerve fibers in the patients' entorhinal cortex during learning, they later recognized landmarks and navigated the routes more quickly," said Fried. "They even learned to take shortcuts, reflecting improved spatial memory.

"Critically, it was the stimulation at the gateway into the hippocampus - and not the hippocampus itself - that proved effective," he added.

The use of stimulation only during the learning phase suggests that patients need not undergo continuous stimulation to boost their memory, but only when they are trying to learn important information, Fried noted. This may lead the way to neuro-prosthetic devices that can switch on during specific stages of information processing or daily tasks.

Six million Americans and 30 million people worldwide are newly diagnosed with Alzheimer's disease each year. The progressive disorder is the sixth leading cause of death in the United States and the fifth leading cause of death for those aged 65 and older.

"Losing our ability to remember recent events and form new memories is one of the most dreaded afflictions of the human condition," said Fried. "Our preliminary results provide evidence supporting a possible mechanism for enhancing memory, particularly as people age or suffer from early dementia. At the same time, we studied a small sample of patients, so our results should be interpreted with caution."

Future studies will determine whether deep-brain stimulation can enhance other types of recall, such as verbal and autobiographical memories. No adverse effects of the stimulation were reported by the seven patients.

Fried's coauthors included first author Nanthia Suthana, as well as Dr. Zulfi Haneef, Dr. John Stern, Roy Mukamel, Eric Behnke and Barbara Knowlton, all of UCLA. The research was supported by grants from the National Institute of Neurological Disorders and Stroke and the Dana Foundation.
