Nine Brain Quirks You Didn’t Realize You Had

Nine Brain Quirks You Didn’t Realize You Had
On Cell Phone

I think the brain is most interesting when it doesn’t work the way you expect it should. Psychology often confirms our intuitions about how our minds work, but it offers quite a few surprises as well. Although some psychology buff’s will have heard a few of these before, here’s a list of quirks in your brain you probably didn’t realize you had:

1) Your short-term memory has a max capacity of seven.

Humans have three forms of memory: sensory, long-term and short-term. Long-term memory is like hard-drive space, while short-term memory works like a very small RAM. This short-term memory can hold only about five to nine (average is seven) items at a time.

Remembering information longer than this requires you to either compress it down into seven units or store it in long-term memory. Most phone numbers are only seven digits.

2) Chartreuse is the most visible color.

Yellow-green, chartreuse, sits right in the middle of the frequencies of visible light. Your eyes have receptors for blue, green and red. Being in the middle, yellow-green triggers the most of these receptors to fire, making it easy to spot. In some cities, firetrucks have been changed from red to a yellow-green color to make them more visible.

3) Your subconscious is smarter than you are.

Or at least more powerful. In one study, a square was assigned to a location on a computer screen through a complex pattern. After watching it, people began to get results better than chance of picking out where the square would pop up next. But when asked to consciously determine the pattern, even given a few hours, nobody could do it.

4) You have two nervous systems.

One set controls excitation and the other controls inhibition. If you hold out your hand, you might notice minor tremors. This is caused by slight, random differences in the amount each of the two systems are firing.

5) Your brain is awful at probability.

Okay, so maybe your high-school math teacher could have told you this one. But, what’s interesting isn’t that your brain is bad at probability, but how. In one study recipients were asked:

Linda is 31 years old, single, outspoken, and very bright. She majored in philosophy. As a student, she was deeply concerned with issues of discrimination and social justice, and also participated in anti-nuclear demonstrations.
Rank the following statements from most probable to least probable:Linda is a teacher in an elementary school.

  1. Linda works in a bookstore and takes Yoga classes.
  2. Linda is active in the feminist movement.
  3. Linda is a psychiatric social worker.
  4. Linda is a member of the League of Women Voters.
  5. Linda is a bank teller.
  6. Linda is an insurance salesperson.
  7. Linda is a bank teller and is active in the feminist movement.

Almost 90% of students responded that #7 was more probable than #5. This is despite the fact that to be a bank teller and in the feminist movement is completely contained within the set of #5 (just being a bank teller). It seems our minds like to think more details make events more probable, not less.

6) Your memory isn’t great either.

Studies have shown that people are highly likely to misremember past events. Even worse, it is incredibly easy to suggest a memory that never happened. This is why so-called “repressed” memories should be given a lot of thought. It is far easier to suggest a memory of an event never happened, then it is to recover one that actually did.

7) You can perceive depth with one eye.

It’s a myth that depth perception is entirely the result of having two eyes. Binocular vision does assist in making a three-dimensional picture. However, most of your ability to perceive depth comes from inside your brain. It has been wired to look at angles and proportions to judge distance.

If you required two eyes to perceive depth then most optical illusions wouldn’t work and it would be incredibly difficult to gather information from flat photographs. Not to mention a lot more one-eyed pirates walking overboard.

8 ) Long-term memory shuts down during sleep.

The parts of the brain that transfer information to long-term memory shut down while sleeping. This is why dreams quickly fade away after you wake up. Although you may have several dreams in a night, they aren’t being recorded into long-term memory. Generally only the fragments of a dream left in short-term memory have a chance to be encoded after you wake up.

9) You have an instant playback feature.

At the beginning I mentioned that humans have three forms of memory, short-term, long-term and sensory. Sensory memory is your brain’s equivalent to an instant playback feature. Working for both your vision and hearing, your thalamus can resend signals a few seconds after they were originally sent.

Imagine being at a party and overhearing someone say your name. Often you can recall what they said even though you were focused on another conversation. This is because your sensory memory re-sends the signals when it finds something important, such as your name. If you lacked this form of memory, activities such as multitasking or taking notes from a speaker would be impossible.

If you’re asked to repeat something you just said because the other person wasn’t listening, just wait a few seconds. Often they can replay the message in their head and give a response.

8 Steps to Continuous Self Motivation Even During the Difficult Times

8 Steps to Continuous Self Motivation Even During the Difficult Times

Many of us find ourselves in motivational slumps that we have to work to get out of. Sometimes it’s like a continuous cycle where we are motivated for a period of time, fall out and then have to build things back up again.

There is nothing more powerful for self-motivation than the right attitude. You can’t choose or control your circumstance, but you can choose your attitude towards your circumstances.

How I see this working is while you’re developing these mental steps, and utilizing them regularly, self-motivation will come naturally when you need it.

The key, for me, is hitting the final step to Share With Others. It can be somewhat addictive and self-motivating when you help others who are having trouble.

A good way to have self motivation continuously is to implement something like these 8 steps from Ian McKenzie.[1] I enjoyed Ian’s article but thought it could use some definition when it comes to trying to build a continuous drive of motivation. Here is a new list on how to self motivate:

1. Start Simple

Keep motivators around your work area – things that give you that initial spark to get going.

These motivators will be the Triggers that remind you to get going.

2. Keep Good Company

Make more regular encounters with positive and motivated people. This could be as simple as IM chats with peers or a quick discussion with a friend who likes sharing ideas.

Positive and motivated people are very different from the negative ones. They will help you grow and see opportunities during tough times.

Here’re more reasons why you should avoid negative people: 10 Reasons Why You Should Avoid Negative People

3. Keep Learning

Read and try to take in everything you can. The more you learn, the more confident you become in starting projects.

4. See the Good in Bad

When encountering obstacles or challenging goals, you want to be in the habit of finding what works to get over them.

Here are 10 tips to make positive thinking easy.

5. Stop Thinking

Just do. If you find motivation for a particular project lacking, try getting started on something else. Something trivial even, then you’ll develop the momentum to begin the more important stuff.

When you’re thinking and worrying about it too much, you’re just wasting time. These tried worry busting techniques can help you.

6. Know Yourself

Keep notes on when your motivation sucks and when you feel like a superstar. There will be a pattern that, once you are aware of, you can work around and develop.

Read for yourself how the magic of marking down your mood works.

7. Track Your Progress

Keep a tally or a progress bar for ongoing projects. When you see something growing, you will always want to nurture it.

Take a look at these 4 simple ways to track your progress so you have motivation to achieve your goals.

8. Help Others

Share your ideas and help friends get motivated. Seeing others do well will motivate you to do the same. Write about your success and get feedback from readers.

Helping others actually helps yourself, here’s why.

What I would hope happens here is you will gradually develop certain skills that become motivational habits.

Once you get to the stage where you are regularly helping others keep motivated – be it with a blog or talking with peers – you’ll find the cycle continuing where each facet of staying motivated is refined and developed.

Too Many Steps?

If you could only take one step? Just do it!

Once you get started on something, you’ll almost always just get into it and keep going. There will be times when you have to do things you really don’t want to: that’s where the other steps and tips from other writers come in handy.

However, the most important thing, that I think is worth repeating, is to just get started.

Get that momentum going and then when you need to, take Ian’s Step 7 and Take A Break. No one wants to work all the time!
