Brain Tricks – This Is How Our Brain Works
You may not realize it but your brain actually processes information in two very distinct ways. Like when you look at this photo you instantly know she has blonde hair, is visibly angry and likely has some choice words to yell. Without any effort you experienced fast thinking, But if you look at the following problem something different happens. Sure you immediately know it’s a multiplication problem and you knew you could solve it if you had the energy, but didn’t.
If you do try your muscles will tense, your pupils will dilate and your heart rate will increase. Now you’ve experienced slow thinking. These two systems of fast and slow thinking dictate much of our perception and reaction in life. Take these lines for example, it is clear that they’re different lengths, but if you measure them they’re actually the exact same length. Even now that you know, system one, or your fast thinking can’t stop seeing the illusion because it acts automatically. A similar effect is seen here, which figure is the largest? Again they are all the same size but the suggestion of perspective and depth causes your system one to interpret the picture as three-dimensional even though it’s on a flat two-dimensional surface. It’s making quick work of the available information and so you’re conscious system two, or slow thinking, must compensate after the fact and choose not to believe your intuition or instinct. Want to see your system two in action? I’ll show you a string of four digits, you read them aloud and add one to each of the original digits.
Motion-induced blindness :-
If you focus your eyes on a blinking red dot in the center of a spinning circle, you will notice something strange: the yellow dots disappear. That’s because attention is like a spotlight that can only shine on one thing at a time, Silva said. In this case, the eyes (and, ultimately the brain) assume that the dots are part of the background, and thus adapt to the dots’ presence and disregard them as unimportant, Kolber said.
Flash lag :-
The flash lag experiment illustrates this gap between perception and reality (click on the link to play the game). Follow the instructions to the game and click on the spot where you think the dot is at the time of the flash.The experiment shows the “difficulty in accurately detecting the position of an object at the time of another event,” according to researcher and author Dean Buonomano.
The Reward Network: How to Structure Incentives :-
As early as the turn of the 20th century, scientists were speculating that we could create a “hedonometer” that would measure the amount of pleasure or displeasure we feel in response to any stimulus. Neuroscience now shows that the reward network is, in some ways, that hedonometer. In case you’re thinking that we can scan people’s brains and see if Bud Light or Miller Lite produces a higher reading on the hedonometer, it’s not that simple. Pleasure and rewards are contextual and can be altered for any given stimulus by the presence of other stimuli. You may register higher for Bud Light because you think you’ll get free beer if you choose that. Or maybe Miller Lite scores lower because you don’t like it from a can, but you would have a different response to a bottle.
The Affect Network: How to Use Gut Instinct :-
In decision making, does intuition outperform careful deliberation? The debate is ongoing. Gauging how much trust to place in hunches is much easier, however, once you have a basic understanding of where they originate, why the brain generates them, and what function “feelings” serve.Scholars have converged on an explanation of how the brain produces the emotional responses that we call feelings: Events in the environment trigger physiological changes (alterations in blood pressure, heart rate, body temperature), which the brain then interprets in context. Some events may have intrinsically affective properties (an electric shock is inherently unpleasant) or may have acquired emotional value through repeated association (over time the sound of a favorite colleague’s voice might engender excitement).
The Control Network: How to Create Achievable Goals :-
Although we can execute many everyday activities on autopilot, we also have a remarkable capacity to override our habits and impulses. We can decide to sit in a different spot at the 1,001st staff meeting even after sitting in the same place for 1,000 meetings prior. If we believe it will help us get a promotion, we can choose to work in a remote and dreary corner of the world away from loved ones. The control network is responsible for this flexibility. It aligns our brain activity and our behavior with our goals. Much as a CEO might reallocate a firm’s resources from a failing market to a growth market, the control network shifts blood flow away from brain regions emitting competing or inappropriate signals and toward regions that help us achieve our objectives.
