Internal speech, that voice that most people hear inside their minds when they think, whether in the form of a monologue or a dialogue, is still a mystery to science. Is it bad or good to talk to yourself? It depends. In this documentary video in Spanish we tell you the secrets of internal speech so that you can reflect a little more about yourselves. #documentary #psychology #science Since ancient times, man has been aware of what current scientists call internal speech, that voice or voices that we hear inside our heads, those verbalized thoughts directed at ourselves. Already in ancient Greece, Plato, for example, considered that thinking was nothing other than talking to yourself in silence. “Did I lock the door when I left the house?” you ask yourself mentally when you are already getting on the bus. “Yes, I sure did... Phew, it's hot in here! Oh, look how nice, there's a free seat there. No, wait, first offer it to that lady who is standing.” All this self-talk is completely normal. Experts estimate that between 20 and 25% of our daily mental activity consists of talking to ourselves. But is all this internal chatter good or bad for our mental health? That depends, as we will see later. First, let's answer another question: how do people develop the ability to talk to ourselves? According to experts, it evolves in tandem with language. It is very common to hear young children think out loud. For example, if they touch a burning object, they say "hot" and let it go. This type of speech, which is not directed at another person but simply expresses a thought verbally and audibly, as if it were a reflection out loud, has been the subject of study by psychologists for many decades. In the 1920s, Swiss developmental psychologist Jean Piaget proposed that children's words reflect their inability to communicate effectively with other people—because they are unable to put themselves in someone else's shoes—and that they therefore limit themselves to communicating with themselves. According to this perspective, as children grow older and learn to speak effectively with other people, they abandon their private dialogue. But in the 1930s, Russian psychologist Lev Vygotsky hypothesized that what children actually do when they think out loud is reuse the words they learn, having used them successfully in interactions with other people, and use them to regulate their own behavior, that is, to control themselves, to learn to manage their own emotions and actions. Vygotsky's ideas, which seem correct in the light of research in subsequent decades, suggest that our internal dialogue as adults shares the same genesis as the private speech we practiced out loud as children. In other words: the conversations we have with ourselves developed from the dialogues we have participated in with other people throughout our lives. Thank you for visiting our channel.
