Errors in body language that make others perceive you as a weak person:

Nobody wants to look weak. However, some people look like that - often at their own request. Body language reveals them. Avoid these mistakes in communication with other people to give the impression of a firm, confident person.

To know the most common errors related to body language, Business Insider talked to Lillian Glass, an expert in communication and body language, as well as the author of the book "Toxic People".

Your parents were right to bore you telling you to sit straight at the table. A slouching attitude doesn't just make others perceive you as weak. It can also result in you starting to see yourself. A 2015 study published in "Health Psychology" suggests that people who often slouch are more likely to fall into negative moods and have lower self-esteem.

1. Hunched shoulders
Your parents were right to bore you telling you to sit straight at the table. A slouching attitude doesn't just make others perceive you as weak. It can also result in you starting to see yourself. A 2015 study published in "Health Psychology" suggests that people who often slouch are more likely to fall into negative moods and have lower self-esteem.

2. Head bowed
This is an obvious error that does not need to be specifically explained. If you often bow your head, people will pick you up as defeated.

3. Soft, shy voice
Nobody will see you as a good leader unless you are heard. If you're a rather quiet and secretive person since birth, try to speak louder, more firmly. You will gain more respect among colleagues.

4. A frightened facial expression
Some are born with it. They just have a face that evokes certain associations - scared, slandered, hostile. They can't really do anything about it. But you can. Control your facial expressions, even if you are scared or nervous, don't let it show at work, especially when you communicate with others.

5. A sly or scowling look
According to Lillian Glass, this is the worst of all body language errors. If you are talking to someone, do not look away, do not drop them on your own shoes, do not jump over everything but your interlocutor. Why? Because you will get upset or - even worse - dishonest.
