Gaming to Greater Cognition

“Stop playing those video games Aaron, they will rot your brain. Starring at that screen that much is going to damage your eyes.” My mother, just as many others, believed that video games were entirely useless and detrimental to a developing child’s mind. I have been a gamer for all of my memorable life. Pretty most people I meet, who are not at least minor gamers themselves, find video games to be a waste of time and pointless. With over 155 million Americans gaming regularly, and gaming trends increasing in countries all over the world, research into the effects of gaming have become a popular study.

Video games have advanced significantly in the past 20 years. There are so many different types of games with varying complexities, publishers, and gameplay. One of the most popular genres of games is action video games which include popular examples such as Call of Duty, Grand Theft Auto, Battlefield, Halo, and many more. Most of these action video games are ones that many concerned parents believe promote violent behavior. This notion that action or violent video games promote violent behavior has been disproven by many studies. These video games do have an effect on people, just not in the negative way that many people believe.

Researchers such as Matthew Dye, Shawn Green, and Daphne Bavelier wanted to examine the effects that action video games had on human cognition. Their study examined how action video games influence perceptual processing. They found that (action) video games provided an efficient training regimen that increased the speed of perceptual reactions in participants without decreasing accuracy. Not only does gaming seem to increase perceptual processing, but a meta-analysis of action video games found that they can also enhance top-down attention and spatial cognition. It was also found that regular gamers had superior multitasking abilities than the average person, even those that claimed to be excellent multitaskers.

It is amazing to know that I have been working hard to improving my cognition and not just wasting my time playing video games. A month after Call of Duty: Balck Op’s release the game had been played the equivalent of 68,000 years worldwide. That amount of time is shocking, and its even more shocking to think what a game designed specifically to increase cognitive function could achieve. Although not all games are created equal in their ability to positively influences cognition, researchers have begun to try to isolate what aspects of these video games are resulting in these positive effects. Daphne Bavelier hopes that by teaming up with entertainment-media experts, researchers can try and find a way to use video games to better understand the brain functions utilized during gameplay. Then, researchers can use that knowledge to provide new and more engaging games that can be used to train and rehabilitate cognitive functions in children, adults, and patients. This positive effect that video games have, and how it could be utilized in the future is explained by Daphne Bavelier in the TED Talk included below.

Having a large sweet tooth may lead to Alzheimer’s

A high-sugar diet has developed a negative connotation over the past few decades. This can be attributed to the countless studies showing the adverse effects sugar can have on the body physically.

To further fuel the negativity associated with sugar, a recent study has found that high blood sugar levels are linked to negative cognitive effects in their participants.

The study, published in Diabetologia, observed 5,189 participants over a period of about 8 years. Their results concluded that all participants demonstrated a cognitive decline over this time span. Interestingly, however, those patients with observed high sugar levels demonstrated a much faster rate of cognitive decline than those with healthy sugar levels.

The study above exposes a clear relation between high sugar levels and cognitive decline, but this revelation is far from ground-breaking. Some scientists have long been referring to Alzheimer’s as ‘type-3 diabetes’. This name came about due to the fact that individuals with diabetes have a higher chance of developing Alzheimer’s.

For me, this is a scary prospect. As a woman with a genetic disposition to diabetes and a sweet tooth propelled by the overwhelming amount of sugar in the South Asian diet, I am a clear candidate for developing Alzheimer’s.

How exactly does this development occur, though?

Dr. Eric Berg, from his YouTube channel Dr. Eric Berg DC, explains the mechanism behind the phenomenon in the video below.

In the video, Dr. Berg states that those with high sugar levels develop insulin-resistance in the body, which results in low sugar metabolism. This ‘starves’ the brain and creates significant memory failures, leading to Alzheimer’s. In the end, he mentions cutting out sugar from our diets entirely, to help prevent the development of the disease.

Cutting sugar out of our diets is no simple thing, however. The Keto Diet Podcast touches on some societal barriers when it comes to switching over into diets that involve less sugar. In her interview with Amy Berger regarding her book, The Alzheimer’s Antidote, Leanne Vogel mentions that even after a run fundraising for Alzheimer’s the meals offered included many dishes with carbohydrates, with few alternative options. She also mentions the candies being ever-present in her grandfather’s care home, despite him having developed the disease already.

Excess sugar leading to Alzheimer’s disease is a link that may now be considered a fact due to the overwhelming amount of evidence. In order to ensure a future of all round health, we should take care of avoiding extra sugar in our diet. Personally, I plan to replace the chocolate bar with an apple, skip the mid-day Frappuccino, and have the medicine go down without a spoonful of sugar.

How much can babies really understand?

Whether you love them or hate them, at some point in your life you have likely talked to a baby. Often, we don’t associate them to have a vocabulary that goes anything beyond “goo goo gaga” so we don’t expect them to understand the slightest of what we are saying. It isn’t until they’re nearly two years old that we expect them to start speaking and communicating in comprehensible language. However, studies have shown that infants at 6 months of age may be able to comprehend the meanings of common nouns.

In Bergelson & Swingley’s study, they presented images to infants between the ages of 6 and 9 months while parents named the objects in the pictures. When named, the researchers found that the infants would gaze towards the associated image. This study suggested that infants were able to understand their parents before 15 months of age, which was previously thought to be the age where understanding began.

Setup for Bergelson & Swingley’s study on infant understanding. Sourced from their published study,

Now this work inspired further investigation. How much do these infants really understand? Do all infants equally develop understanding of common nouns at the same points in life? Bergelson performed a more recent study that suggested infants are more easily able to tell the difference between words that are semantically unrelated, such as milk and foot, than when they are related (milk and juice). This was the first time infants of this age were observed utilizing their understanding of phonemes to comprehend human language.

It seems obvious that an infant would not be able to make that distinction as easily; however, this lack of distinction is also observed in adult understanding of languagePrevious studies have been conducted like the Bergelson & Swingley study, in which images were placed before adult participants and their eye movements were tracked when words were spoken to them. A delay in eye fixation was observed when related images were shown to the adult participant versus images that were completely unrelated. As it turns out, our understanding of common nouns is not far from that of a 6-month old infant. This is the first time a similarity in language comprehension of this scale has been observed between adults and infants at the age of 6 months.

New developments such as this suggest that infants are learning and developing understanding on a much faster rate than previously thought. It’s worth noting that there are short-comings to this research. For one, there were only 51 children studied and most of the infants were from white, middle-class families. However, this opens the door to further studies on infant cognition. Perhaps next time we talk to a baby, we might be more careful with the words we choose, because it seems that they understand more than what we once thought.
