We take it for granted that witty anecdotes make us laugh, and sad stories – cry. We hiccup and blink, not giving these actions some special significance. And meanwhile, all these things are explained, if not by physiology, then by psychology, helping the body to work in full force.
In our material – a dozen “strange” things that we do every day.
Look at your hands again. You have two, right? Then why are you inclined to use only one of these appendages to solve problems? According to scientists, left-handed or right-handed, the fact that you have a dominant hand is a little strange. In the end, two hands with the same motor skills would solve many of our problems.
As an explanation why we use only one hand, there is a theory related to how the brain processes speech. According to her, the left hemisphere of the brain, in which the center of speech is located in most people, is more complex in structure than the right hemisphere. Perhaps, it is because of the greater number of “details” communicating with each other, responsible for the management of the right hemisphere of the brain, that people are more likely to write and eat with their right hand.
Like it or not, gossip is a part of our daily life. And scientists suggest that in fact, they bring us closer to people around us. In an interview with Live Science, Robin Dunbar, a professor at Oxford University, compares gossip to the behavior of primates. Baboons collect beetles from the backs of each other, and we, people, talk about someone behind us. According to the expert, this is a kind of verbal glue that supports our social ties.
Other researchers agree with her. For example, Jennifer Bosson, a professor of psychology at the University of South Florida, who believes that sharing our dislike helps develop an emotional bond between the gossip and the listener.
Forgets the facts
It seems that forgetting small pieces of information is not at all scary. But how can you forget why you came into the room, what did you want to buy at the pharmacy or when the birthday of your own child? In fact, this is also quite normal.
According to researchers, many things can lead to memory latency. Some of the most common causes are stress and sleep deprivation. However, according to a study published in 2011 in the journal Experimental Psychology, you do not need to go through a stressful overload in order to forget this or that fact. Triggers can also become “accumulated stress” and many other random things.
According to researchers, boredom stems from the objective absence of neurological arousal, which causes a subjective psychological state of dissatisfaction, frustration or lack of interest. And, some people are more prone to boredom than others. According to studies published in the journal Perspectives on Psychological Science in 2012, people who gravitate toward cognitive impairment and attention deficit may be more susceptible to boredom.
“In this age range, the frontal cortex is in the final stages of maturation, promoting better self-control and self-regulation,” says Live Science James Danckert, professor of cognitive neurology at the University of Waterloo.
Thinks of death
Have you ever thought about dying? If you answered “no”, then either you are joking or just different from other people. Statistics make it possible to say that thoughts of death are common and natural, so they should not be frightened. According to experts, the whole point here in our “sophisticated” brain, which literally makes us realize the inevitable death of a person, facing the biological desire in life inside us.
Psychologists note that in some people these thoughts cause anxiety, while others, on the contrary, desire to live and create. In any case, if they do not persecute you constantly, you have no cause for concern.
Does something bad
Smoking, drinking alcohol, and also two burgers with potatoes and cheese sauce – all these things are more or less harmful to us, but we are not in a hurry to stop self-destructive behavior. Why? Scientists call several reasons. First of all, such habits can be caused by a genetic predisposition to dependencies. In addition, this may be due to the age and / or information that a person received on this issue (more precisely, in this case, just missed).
“We tend to live here and now, and in the organic future. But a person very rarely thinks in the long run, “comments Cindy Jardine, a professor at the University of Alberta, in an interview with Live Science.
Hiccups are involuntary spasms of the diaphragm, the muscle shell in your chest, which is extremely important for breathing. Spasm occurs when the muscle is irritated: for example, due to the presence of too much food in the stomach or, on the contrary, due to insufficient food throughout the day.
The oddity is that hiccough is completely useless. That is, it does not serve any specific purpose, but, according to a number of researchers, it may be a remnant of a primitive sucking reflex.
Despite numerous studies, scientists still can not say for sure why people dream. One of the theories proposed by Harvard University psychologist Deirdre Barrett suggests that people dream to solve actual problems. In particular, visual and sometimes completely illogical dreams help us think about problems in a different way, in a different way than we could do it in real life. According to Barrett, this kind of unconscious thinking helps to find a non-banal way out of this situation.
Another fairly common theory is that people dream simply because in this way they can throw out the accumulated creative energy.
It’s getting red
It turns out that the reaction of redness of the cheeks is a universal reaction of a person to social attention. Another thing is that, depending on the individual characteristics of the body, someone does it more, and someone less (in the same way – more often or less often). Usually, cheeks turn pink when you receive a compliment from someone who is really important to us, or under the influence of strong emotions.
At the biological level, it happens like this: the blood vessels on the skin surface expand, causing the blood to flow to them, and thus coloring the face in shades from gently pink to bright red.
In fact, it’s not so strange that we blink: blinking once every 10 seconds allows you to clear the mucous from dust particles and provides the eye with “lubricating fluid”, keeping it moisturized. Strangely, this means that we do not notice at all how every 10 seconds the world around us plunges into darkness.
Scientists have found that the human brain has the ability to ignore the instantaneous blackout. The secret is that the very process of blinking suppresses activity in several areas of the brain responsible for detecting changes in the environment so that you feel the world around you as integral and continuous. It’s amazing, is not it?
