Researchers have disproved the myth that video games are bad for developing
brains by finding a link between children's improved intellect and how much
time they spend playing them.
Even while the difference in cognitive capacity was small and not strong
enough to show a cause-and-effect relationship, it was noticeable enough to
be noted, and the study made sure to take into consideration factors like
parenting style and genetics.
On the other hand, social media use and TV watching did not seem to have
any impact on IQ. The results should be useful in the debate over how much
screen time is suitable for developing children's minds.
The researchers wrote in their analysis that "digital media characterizes
modern infancy, yet its cognitive impacts are obscure and widely
discussed."
"We feel that genetic data studies might help to clarify causation claims
and account for the often overlooked function of genetic
predispositions."
9,855 children in the ABCD Study who were 9 or 10 years old and resided in
the United States had their screen time data reviewed by the researchers.
The children said that, on average, they watch TV or view videos online for
2.5 hours a day, play video games for an hour, and use the internet for half
an hour.
Researchers examined data for nearly 5,000 of those children two years
later. Those whose video game playing time above the average increased their
IQ by 2.5 points throughout the duration of the study.
The children's success on reading comprehension, visual-spatial processing,
memory, flexible thinking, and self-control tasks provided the basis for
their increase in IQ.
The study, which focused solely on children in the US and did not
differentiate between mobile and console game genres, still offers important
insights into the relationship between gaming and IQ and lends credence to
the idea that intelligence isn't a set trait that we all possess from
birth.
According to neurologist Torkel Klingberg of the Karolinska Institute, "Our
results support the claim that screen time does not impair children's
cognitive capacities generally and that playing video games can really
assist increase intellect."
The researchers note that there appear to be other benefits to playing
video games in addition to the association between children's gaming time
and cognitive capacity that has been shown in previous studies.
The researchers claim that the contradictory findings about the effects of
screen time that have been discovered thus far are a result of small sample
sizes, a variety of study designs, and a failure to take genetic and
socioeconomic variables into account. These are the limitations that this
study tried to solve.
All of this suggests that a great deal more research is necessary since
there are a lot of variables at play when it comes to how intelligence grows
and develops as well as the different ways that screen time impacts our
bodies and habits.
"We didn't look at the impacts of screen time on physical activity, sleep,
wellness, or school achievement," says Klingberg.
