1. Music Changes Perception: Did you know that the type of music you listen to actually impacts your perception of the world around you.
Music can completely spin your mood. For example, a “Whenever you’re ready...I surrender” would get you falling in love all over again with the ‘boo’, or at worst, if there’s no boo, it’ll trigger the “God when?” part in you. Meanwhile, a song like Sub Urban’s “Cradles”, sets you in a completely different mood. Music creates perceptual expectation, hence, your brain expects to see something similar to what you hear, through your eyes.
2. Foreign Language Logic: Our reasoning skill is divided into parts:
- Systematic and logical
- Unconscious and emotional
Our emotional part dominates when we use our first language. Our judgement then is clouded. On the other hand, our logical side takes dominance when we use a foreign language (a less natural language).
3. The Dunning-Kruger Effect: This Effect proves the old adage which says “Ignorance is bliss”. Discovered by two social psychologists in 1999, “The Dunning-Kruger Effect” is about two extreme sets of people; intelligent and unintelligent people. According to the effect, intelligent people hardly think they are smart and often rate themselves below average while on the other hand, people with low intelligence do the exact opposite.
"In many cases, incompetence does not leave people disoriented, perplexed, or cautious, instead, the incompetent are often blessed with an inappropriate confidence, buoyed by something that feels to them like knowledge." David Dunning in his article for Pacific Standard.
Incompetent people tend to: Overestimate their skill levels, not recognize the genuine skill and expertise of other people, not recognize their own faults and lack of skill. Meanwhile, Competent people are the direct opposite.
How can you overcome “The Dunning-Kruger Effect”? Learn more, speak to people, be open minded and willing to accept criticisms.
4. Singing Reduces Anxiety: Research has shown that singing can decrease symptoms of anxiety, depression, and stress. Great voice or not, singing releases endorphins and oxytocin to your brain.
5. Rejection Hurts: our brains are wired to feel pain from rejection. They process physical and emotional pain the same way. The same chemicals are released, and same areas are activated with both kinds of pain. This explains why rejection hurts badly.
6. Remember Remembering: A Northwestern Medicine study, likens our memory to the telephone game we played as kids. According to the study, our brain networks change in ways that can alter an event recall each time we remember an event from the past. Hence, when we think back to that memory, our mind isn’t going back in time, it’s remembering the last time we remembered.
7. The Negativity Gene: A 2013 study by a University of British Columbia researcher, published in Psychological Science finds that some people are genetically predisposed to see the world darkly. The study finds that individuals can perceive emotional events, especially negative ones more vividly than others due to previously known gene variants. In that study, researchers looked at how people with the negativity gene reacted to various images. Although most people loved pictures of waterfalls and beaches, people with this gene found them dangerous and alarming. From the study, there is a possibility that naturally cautious or negative people might have just been born that way.
8. Canonical Perspective: We’ll refer to it as “to the side and slightly above”. A canonical perspective basically refers to how things look in our memory. When asked to draw an image of a teacup, most people worldwide drew it from the side with a roughly 30-45 degree tilt. This way, you could see a bit of the top. That means humans reflexively see most objects from the exact same viewpoint; the side or slightly above.
9. Evolving Anxiety: Mental health is more and more becoming a thing of great concern. Mental health conditions are becoming increasingly common with Anxiety being the most common mental illness in the world, affecting 284 million people. (Our World in Data, 2018). Now, more than ever, it is more crucial to pay attention to your mental health.
10. Dopamine Addiction: While dopamine does play a role in addiction, this role is complex and not fully understood. Not only does dopamine control desire, It compels you to get something when you want it. Dopamine is commonly known to be what triggers you to scroll long hours through social media. Dopamine sends pleasure signals to the brain each time you do. You might want to put this in check as the longer you let it continue, the more difficult it is to break.
11. The Over-Sleepers Paradox: If you’d feel restless, cranky, and weak when you haven’t had enough sleep, you’d definitely feel the same way if you’ve had too much sleep. Sleep, -natural as breathing, essential as food- can sometimes be harmful to our health. Psychologists say that sleeping too much is as harmful as not sleeping enough. Oversleeping in fact has been linked to a number of medical issues as heart disease, diabetes, and increased risk of death. That being said, sleeping the perfect amount cannot be overemphasized. It is the only way to not feel tired after sleeping, and avoid the risk of health complications. So how do you sleep the right amount?
According to the National Sleep Foundation, the amount of sleep a person needs each day varies with age,
- Newborns (0-3 months) need 14-17 hours
- Infants (4-11 months) need 12-15 hours
- Toddlers (1-2 years) need 11-14 hours
- Preschoolers (3-5) need 10-13 hours
- Children (6-13) need 9-11 hours
- Teenagers (14-17) need 8-10 hours
- Adults (18-64) need 7-9 hours
- Older adults (65+) need 7-8 hours
12. Mood Sickness: Our bodies and brains are linked together. That means if your brain is down, then your body too will be, and vice versa. Bad moods not only impact our brain but can significantly affect our physical health. So you might have lower immune function when you’re feeling unhappy. A healthy life is a happy one, therefore it is important that you constantly find ways to improve your mental state daily.
13. Reading Faster: Years ago, publishers figured that if lines were shorter, people were more likely to keep reading, so newspapers kept their lines between 30 and 50 characters. The idea being that short lines enhance speed reading. However, Psychologists recently discovered the opposite; we read faster with longer lines.
14. The Power of Sunlight: Ever felt down from staying inside all day, but your mood changes immediately you step out? That’s the power of sunlight. The vitamin-D gotten from the sun releases pleasurable hormones to the brain, and serves as a mood balancer. Previous research suggests people in countries with less sunlight are more likely to be depressed. While this might be true, a 2020 Dutch study of 5,282 people found that less sunlight doesn't actually influence moods. Though recent research suggests that a lack of sunlight doesn't affect our mood, it's important you seek expert opinion if you feel that you are struggling.
15. Healthy Sarcasm: Do you notice that sarcastic people are often highly intelligent people? Studies have shown that sarcasm can improve brain health. While some may find sarcasm offensive, research has found one of the benefits of sarcasm to be greater creativity. Sarcastic people tend to be witty, smart, sharp, and creative.
