20 surprising psychological Facts

There are up to 20 psychological curiosities that, surely, you did not know or had overlooked. Today we are going to address them so that you know things that, without a doubt, will surprise you! Start with us this wonderful journey that will allow you to explore previously unknown lands.

One of the most surprising psychological Facts is that, far from what we believed, we do not learn while we sleep!

  1. We have one side of the face more expressive than the other

Yes, the first of the psychological curiosities that we are going to address is that our left side of the face is more expressive than the right. This is so for all people, why didn’t you expect it?

  1. The cerebral hemispheres have different functions

While our right brain is related to emotional processing, the left brain is related to language .

  1. We spent 20 years sleeping!

That is, when a person meets 60 years can say that s and has spent about 20 years sleeping. What madness!


  1. By default, nature produces women

One of the psychological curiosities that can generate more controversy is the statement that nature produces women by default, that is, automatically. If male hormones come into play, this is when the fetus develops male characteristics.

These male hormones are known by the name of Antimullerian hormones. Its peculiar name comes from its discoverer  Johannes Peter Müller . Its specific function is to  inhibit the Müllerian duct . That is, the embryonic structure that will form the uterus and tubes, giving rise to the birth of males.

  1. The clock gene is different depending on whether you are an early riser or a night owl

There is a gene (the clock gene) that is different in early risers and night owls. So it is not a matter of mania , it seems that we have different genetic predispositions to be more active at night or during the day.

  1. Pheromones influence sexuality

Pheromones do influence our sexuality. Thus, different effects have been observed in mammals:

  • Lee Boot effect: itconsists of the slowing down or occasional disappearance of the estrous cycle (the menstrual cycle in animals) when they live together.
  • Whitten effect:women’s menstrual cycles are synchronized when they are very close for a continuous time. That is, if you live with a woman or spend a lot of time with one, your ovulation is likely to occur almost simultaneously.
  • Vanderberg effect: puberty or adolescence comes early when females live with males.


  1. Fatal family insomnia is deadly!

There is a condition called insomnia fatal familial. It is hereditary and, suddenly, people who suffer from it cannot fall asleep. They die between 7-24 months after the onset of the disorder.

  1. We don’t learn while we sleep

We don’t learn while we sleep. Not even unconsciously, contrary to popular belief. Sleep helps the body recover, so reviewing for an exam before going to sleep will not guarantee a better internalization of the concepts.

  1. We have all suffered from hallucinations

We have all suffered hallucinations at some point or are susceptible to it. For example, under conditions ofsensory deprivation(Like when we are driving on a monotonous road, we are facing an intense silence and we seem to hear a voice). In addition, we may find that when we wake up we seem to perceive a sound that has not existed ( hallucinations hypnopompic ) or that something has happenedjust that we are falling asleep (hypnagogic hallucinations).

  1. Seeing faces or shapes in the clouds is called pareidolia

Seeing faces or shapes in the clouds or fire has a name, pareidolia. This phenomenon responds to the tendency of human beings to organize the things they see into stimuli that make sense. In fact, there is a theory that states that humans acquired this ability to be able to distinguish faces between the leaves and defend themselves from predators.


  1. Childhood dementia exists

There is childhood dementia and it is associated with diseases such as childhood schizophrenia or other organic degenerative pathologies. These begin very early in life, assuming a barrier to the proper development of these children, probably an irrecoverable loss and a severe blow to the child and their environment.

  1. Freud is not the father of psychology

The well-known Freud was a psychiatrist and is the founding father of psychoanalysis. It is the German Wilhem Wundt  who is recognized as the father of modern psychology . Its importance lies in the creation of the first experimental psychology laboratory where it studied basic reactions and related them to human capacities.

  1. Freud was addicted to cocaine

The one we thought was the father of psychology, Freud, was addicted to cocaine , so much so that he shared his addiction with family, friends and even patients for whom he prescribed it. His addiction began when he used this drug as an anesthetic, as he suffered a lot of pain as a result of cancer.

  1. Living in the country or in the city influences some disorders

It seems that disorders such as schizophrenia occur less frequently in people who live in the countryside than in people who live in cities. It seems that stress has something to do with this …

  1. Depression affects women more

It could be because socially a greater expression of emotions is allowed in women, because there is some type of genetic association with the female chromosomes for this pathology or because other problems such as alcoholism and addictions mask depression in men (it seems that in populations in which alcohol consumption is not allowed, as in the Amish, the tendency is to have equal levels of depression in men and women).


  1. When winter comes, people get more depressed

The season that most depresses is winter, it is believed that it is due to the less exposure to sunlight, since this produces a decrease in serotonin in the brain.

  1. The summer season produces more manic states

The summer season is the one that produces more manic states. This point and the previous one seem to be less evident depending on the latitude in which the people are; thus, people closest to the equator suffer from these problems to a lesser extent.

  1. We suffer micro-awakenings when we sleep

It is possible that when we sleep there are micro-awakenings in which we change our position , but which are so brief that we do not notice them.

  1. The brain of an adult has a certain weight

The weight of an adult brain usually varies between 1200-1400 grams , however the next and last of the psychological curiosities must be taken into account.

  1. We lose brain mass gradually

 From the age of 30 our brain gradually loses mass. This may explain, in part, the reason why we lose memory over the years.
