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.

5 Steps To Move Out Of Stagnancy In Life

5 Steps To Move Out Of Stagnancy In Life

In the journey of growth, there are times when we grow and excel. We are endlessly driven and hyped up, motivated to get our goals.

Then there are times when we stagnate. We feel uninspired and unmotivated. We keep procrastinating on our plans. More often than not, we get out of a rut, only to get back into another one.

How do you know if you are stagnating? Here are some tell-tale signs:

  • If you have been experiencing chronic procrastination on your goals
  • If you don’t ever feel like doing anything
  • If you keep turning to sleep, eating, games, mindless activities and entertainment for comfort
  • If you know you should be doing something, but yet you keep avoiding it
  • If you have not achieved anything new or significant now relative to 1 month, 2 months or 3 months ago
  • If you have a deep sense of feeling that you are living under your potential

When we face stagnation in life, it’s a sign of deeper issues. Stagnation, just like procrastination, is a symptom of a problem. It’s easy to beat ourselves over it, but this approach is not going to help. Here, I will share 5 steps to help you move out of this stagnation. They won’t magically transform your life in 1 night (such changes are never permanent because the foundations are not built), but they will help you get the momentum going and help you get back on track.

1. Realize You’re Not Alone

Everyone stagnates at some point or another. You are not alone in this and more importantly, it’s normal. In fact, it’s amazing how many of my clients actually face the same predicament, even though all of them come from different walks of life, are of different ages, and have never crossed paths. Realizing you are not alone in this will make it much easier to deal with this period. By trying to “fight it”, you’re only fighting yourself. Accept this situation, acknowledge it, and tell yourself it’s okay. That way, you can then focus on the constructive steps that will really help you.

2. Find What Inspires You

Stagnation comes because there isn’t anything that excites you enough to take action. If you don’t have a habit of setting goals, and instead just leave yourself to daily mundanes, it’s not surprising you are experiencing stagnation. What do you want to do if there are no limitations? If you can have whatever you want, what will it be? The answers to these questions will provide the fuel that will drive you forward.

On the other hand, even if you are an experienced goal setter, there are times when the goals you set in the past lose their appeal now. It’s normal and it happens to me too. Sometimes we lose touch with our goals, since we are in a different emotional state compared to when we first set them. Sometimes our priorities change and we no longer want to work on those goals anymore. However, we don’t consciously realize this, and what happens is we procrastinate on our goals until it compounds into a serious problem. If that’s the case for you, it’s time to relook into your goals. There’s no point in pursuing goals that no longer inspire you. Trash away your old goals (or just put them aside) and ask yourself what you really want now. Then go for them.

3. Give Yourself a Break

When’s the last time you took a real break for yourself? 3 months? 6 months? 1 year? Never? Perhaps it’s time to take a time-out. Prolonged working can cause someone to become disillusioned as they lose sight of who they are and what they want.

Go take some extended leave from work. A few days at bare minimum; a few weeks or months will be great. Some of my ex-colleagues have quit their jobs and took months out to do some self-reflection. Of course, some of us might not have that luxury, so we can stick to a few weeks of leave. Go on a trip elsewhere and get away from your work and your life. Use this chance to get a renewed perspective of life. Think about your life purpose, what you want and what you want to create for your life in the future. These are big questions that require deep thinking over them. It’s not about finding the answers at one go, but about taking the first step to finding the answers.

4. Shake up Your Routines

Being in the same environment, doing the same things over and over again and meeting the same people can make us stagnant. This is especially if the people you spend the most time with are stagnant themselves.

Change things around. Start with simple things, like taking a different route to work and eating something different for breakfast. Have your lunch with different colleagues, colleagues you never talked much with. Work in a different cubicle if your work has free and easy seating. Do something different than your usual for weekday evenings and weekends. Cultivate different habits, like exercising every day, listening to a new series of podcasts every morning to work, reading a book, etc (here’s 6 Proven Ways To Make New Habits Stick). The different contexts will give you different stimulus, which will trigger off different thoughts and actions in you.

When I’m in a state of stagnancy, I’ll get a sense of what’s making me stagnate. Sometimes it’s the environment I’m in, sometimes it’s the people I’ve been hanging out with, sometimes it’s my lifestyle. Most of the times it’s a combination of all these. Changing them up helps to stir myself out of the stagnant mode.

5. Start with a Small Step

Stagnation also comes from being frozen in fear. Maybe you do want this certain goal, but you aren’t taking action. Are you overwhelmed by the amount of work needed? Are you afraid you will make mistakes? Is the perfectionist in you taking over and paralyzing you?

Let go of the belief that it has to be perfect. Such a belief is a bane, not a boon. It’s precisely from being open to mistakes and errors that you move forward. Break down what’s before you into very very small steps, then take those small steps, a little step at a time. I had a client who had been stagnating for a long period because he was afraid of failing. He didn’t want to make another move where he would make a mistake. However, not wanting to make a mistake has led him to do absolutely nothing for 2-3 years. On the other hand, by doing just something, you would already be making progress, whether it’s a mistake or not. Even if you make a supposed “mistake”,  you get feedback to do things differently in the next step. That’s something you would never have known if you never made a move.
