The Science of Fantasy

In this lesson, students exercise research skills, persuasive writing skills, and their creativity to create a fake scientific report about an urban legend or mythical creature of their choice.

Tetris

The Tetris Effect: Re-Wire Your Mind

The Tetris Effect:

When the game Tetris was released, it was insanely popular and became an instant classic.  Even the creator of the game himself has said he had trouble finishing the game’s programming because he couldn’t stop playing it during testing!  From the start, the game produced an unforeseen effect on the players’ minds when played very heavily – one that was confusing, somewhat alarming, and ultimately fascinating.

Also known as The Tetris Syndrome, The Tetris Effect occurs when people spend so much time doing a particular activity or pattern of behavior that it inhabits their thoughts, mental images, and dreams.  With Tetris, the players would see the little tetris block formations, or tetronimos, falling and fitting into rows when they weren’t playing anymore.  With other games and activities requiring repetitive behaviors, other similar visual experiences associated with the activity take place.  It is related to something becoming a habit but with real cognitive changes occurring in the brain.

Memory Science:

In psychology, memory is the process through which information is encoded, stored, and retrieved.  There are different types of memory including “declarative memory,” which requires conscious recall.  In other words, some active mental process must occur to recall the information.

Conversely there is “procedural memory,” which is not based on conscious recall but on implicit learning.  Implicit learning takes places when a behavior is learned from repetitive practice.  So procedural memory works when you automatically know how to physically do something without any conscious effort – like tying your shoe, riding a bike, or reading.  Motor skills are developed this way as well as behaviors and patterns of thoughts associated with The Tetris Effect.

Real Studies:

In 2000, a scientist, Robert Stickgold and his colleagues at the Harvard Medical School proposed that Tetris imagery is a separate form of memory likely related to procedural memory.  This is from their research in which they showed that people with anterograde amnesia, unable to form new declarative memories, reported dreaming of falling shapes after playing Tetris during the day despite not being able to remember playing the game at all.

A study conducted by Lynn Okagaki and Peter Frensch in 1994 showed that participants who played Tetris for twelve 30-minute sessions (with no previous experience of the game) did much better than a control group in a spatial skills test.  The result of the experiment was that the game had positive effects on spatial skills abilities including mental rotation, spatial perception, and spatial visualization.

The experience of seeing falling tetris blocks in your mind hours after playing the game can be somewhat alarming, and you might think, “Did I just fry my brain!?”  Playing the game Tetris is very enjoyable for most players, and the somewhat alarming effect of visualizing the game when you aren’t playing it might even have benefits like those described in the studies above.  Overall, it’s a very unique observable scientific phenomenon associated with a popular video game, which is pretty cool.

The Science of Binge Watching

The Instant Gratification of Binge Watching Television:
You watch an episode of your favorite TV series, it’s a cliffhanger!  You see the credits, and feel the pangs of sadness because you will have to wait another week to find out what happens next.  Ten years ago, this was the normal way to watch a television series.  Today, technology allows you to push a button (or just sit back and wait) and your next episode can be viewed right away.  Its a beautiful advancement in these modern times.

Binge-watching, also called binge-viewing, is the practice of watching television for longer time spans than usual, usually of a single television show. In a survey conducted by Netflix in February 2014, 73% of people define binge-watching as “watching between 2-6 episodes of the same TV show in one sitting.”  Binge-watching as an observed cultural phenomenon has become popular with the rise of online media services such as Netflix, Hulu and Amazon Prime where the viewer can watch television shows and movies on-demand.

The idea of assembling several consecutive episodes of a television series in order and watching them in rapid succession originated with the marathon, networks themselves programmed several hours’ worth of reruns of a single series. This practice began in the 1980s and is still popular among subscription television outlets in the 2010s.

Your Body and Mind on a TV Binge:
Here are a few ways the science of binge watching affects your mind, body and soul.

1. The Non-Walking Dead
The effects of sitting for long periods of time have been well documented, and it is generally understood that being sedentary for most of the time is harmful to your health.   Since you’re sitting with your spine in a C shape, it can cause cramped muscles, spinal pressure, and bad posture.  This is a sedentary behavior and if not moderated can lead to weight gain – You are simply not burning many calories if you are not moving your body around.

2. Friday Night Lights
The effects of fluorescent light on the brain have been studied and long term TV watching can have the same effect – too much exposure has been linked to headaches, eye strain, seasonal affective disorder, problems sleeping, poor immune function, hormonal disruption, and anxiety among other symptoms.  Getting out into the sunshine more during the morning and daytime has been shown to combat the negative effects of too much fluorescent light exposure.

3. TV is the new Ice Cream: Depression and Loneliness
Some recent findings on binge-watching associated people who binge on television with depression, loneliness and an inability to control their behavior.  This however, was only a correlational study, and not concluded to be a direct cause and effect relationship.  As mentioned above, this can also be a symptom of too much flourescent light exposure, so its possible these issues are connected in some way.

4. Breaks are for Quitters: Persistence and Resiliency
There are positive effects of binge watching as well.  Based on a survey commissioned by Netflix in December, Three-quarters of 1,500 online respondents reported having positive feelings in binge watching and that binging was a welcome refuge from their busy lives. Nearly eight in ten people said binge-watching a TV show made it more enjoyable than watching single episodes. It would seem that people are craving the long narratives that today’s good television can provide. In today’s world of shortened attention spans, binge watchers have shown an ability to be resilient and focus on a task for long periods of time.

5. This Show is Like My Life Story: Cognitive Empathy
We may become glued to complex, emotionally-charged stories, and want to consume a lot of them, because of our ability to recognize the feelings of others.  In addition to identifying others’ discomfort or elation, this branch of “cognitive empathy” examines how humans can also adopt others’ psychological perspectives, including those of fictional characters. Research has pointed to this occurrence more often with reading fictional texts as opposed to watching a fictional film or television series, in that a more profound emotional reaction occurs while reading as opposed to watching.  But perhaps Binge watching creates more of an emotional bond to characters and scenarios than a shorter time duration.

What it Means to “Binge”:
“Binge” is defined as a short period of time in which you do too much of something.  Inherent in the definition, is a judgement that the behavior is excessive, or somehow suggests the binger is “out of control.”  For some activities like eating, or drinking alcohol, there are real, immediate threats to your well being and these are considered harmful activities.  Perhaps “binge” watching television is not the proper term.  Many people prefer to watch television series this way, and are otherwise responsible, balanced individuals who can moderate their entertainment consumption.  So “binge-watching,” although a very appropriate buzzword to describe the activity, creates too negative a connotation. A few hours is not as excessive as all day marathons.  Getting to watch something you desire is a pleasurable activity, and so if a viewer takes some breaks from sitting for long periods of time, or stretches often enough, the pros and cons can balance out.  Moderation, with all things in life, is the key here.
