Genes, environment or a special bond? Why some twins say and think unanimously

Interview with Paul and Bridgette Powers – identical twins who witnessed their mother’s theft – recently became popular. The way they talked and gestured according to captivating Global audience.

Genetically identical twins clones. They results from Early embryo division, which means that they have the same genes.

Whereas, brotherly twins They are the result of a fertilizer of two fertilizer eggs through two different semen. On average, they divide 50% of their genes – the same as any siblings that divide both their biological mother and father.

So when identical twins speak and gestures in accordance (known as synchronization), is it genes? The answer can be complicated.

Genes are not the only influence on the appearance, language and thinking of a similar moment. Let’s break the factors that could lead some twins to the speech – and apparently think – according to.

A close bond in a common environment

Almost all twins, even “identical”, show some differences in physical, mental and emotional features. They also consider themselves separate people and usually do not like to be called “twins“.

However, we know that most people imitate the way their loved ones tell them and move without even realizing it. This phenomenon is called Automatic facial expressions And it can be part of well social development, helping people synchronize behavior and share emotions.

In the case of identical twins that grow up in the same home, school and community, the effect of a common environment and a close relationship can be particularly intense.

For example, Paula and Bridgette Powers shared the environment: not only the same parents, home and upbringing, but also the same work, conducting a Birds’ Rescue Organization.

The twins can get to know each other so well that they can intuitively feel, every second twin is going to say – and they can feel as if their brain is synchronized. Powers sisters explained:

Our brain must think similarly at the same time.

On the other hand, twins who grow up, divide many personality traits, but without years of interaction they are less likely to develop synchronized speech or mirror behavior. However, they display many of the same unusual habits and idiosyncraz.

What about genetics?

The study of identical and fraternal twins separated after birth can lend a hand us explain how many behaviors of our behavior – intelligence, personality and temperament – have an impact of genes and the environment.

Even when identical twins are distinguished, they tend to recall – not only physically, but in their personality, interests and behavior. Basically, brotherly twins are much less. This tells us that genes matter.

One of us (Nancy) was a researcher from Minnesota Study from the raised twinswhich lasted in 1979–1999 and looked at over 100 sets of twins (and triplets) separated at birth and raised. The twins were separated for various reasons, such as the stigma of lonely maternity, inappropriate family resources and mother’s death.

The study comprehensively examined factors affecting a wide range of psychological, physical and medical features. Scientists wanted to understand the impact of differences in their life stories on identical and brotherly twins, grew up in the postponement and how they influenced the current similarities and differences between them.

AND Striking discovery There were identical raised twins, they are as similar in personality as identical twins raised together. For example, scientists from Minnesota did not find a little difference in the features, as well as well -being and aggression, regardless of whether identical twins were raised together or from each other.

This shows that genes play an vital role in shaping our personality. Genes also affect the way we process speech and language.

Sharing identical genes can mean that identical twins also react to situations in a similar way. This is because their brain preserve them comparable ways. This genetic proximity, which underlies their behavioral similarity, explains why they can say or do the same, without the need for a mystical explanation.

The study in Minnesota also showed that with the re -combination of identical twins, they created closer relationships United brotherly twins again He did. This suggests that the perception of similarity in behavior can combine people and lend a hand them in contact.

We now know genes and the environment, each of them tells half of the person to a person Personality differences. However, life events that we experience individually remain most important A factor shaping the way of expressing our unique features and who we finally become.

What about the secret “twin language”?

Parents of identical twins may be surprised as their children, even as teenage children, seem to communicate through logs and gestures, which no one understand.

Each twin pair has their own way of communication. Private speech of twins, also called Idioglossia, cryptophasia or “secret language” relate to the verbal and non -verbal exchange of most other people does not understand. This is different from synchronized speech.

Private speech is displayed by about 40% twins. However, the estimates are different wildly – from 2% to 2% to 47%. This is mainly due to the fact that researchers define and measure it differently.

Private speech usually disappears with age children aged three years ancient. But some twins still employ it in early childhood.

Why are we so fascinated by twins?

The twins are still fascinating us. It is clear in the richness of the media they receive, their popularity in scientific research and their presence in myths and legends on all continents.

Perhaps this is because when we see identical twins that look and behave as similarly, it questions our belief that we are all special.

But even identical twins are not exactly exactly replicas. Genetic changes, events in the womb and/or life experiences can be plotted in order to create differences between them.

Nevertheless, the most identical twins are more similarly And socially closer than any other couple of people on the planet.
