What causes feelings in us: The mental and psychological state of a living being is called a feeling. Feelings are part of a person's mood and personality. They stem from the individual perspective of a situation. People behave in a way that directly corresponds to their emotional state. The causes of feelings are not yet fully understood, but there are numerous theories on the subject of feelings.

What causes feelings
Theory of physical reaction
Since the end of the 19th century, William James has theorised that physical reactions are the key to a person's emotional state. According to this theory, feelings are caused solely by the actions of the individual. For example, a person cries and feels sad as a result.
The neurobiological theory
Mapping the nervous system shows that the brain of a mammal produces reactions that can be responsible for feelings. Hormones such as dopamine, noradrenaline and serotonin trigger certain reactions in the body that we interpret as feelings.
The cognitive theory
This states that judgement and the evaluation of a situation are at the root of emotions. This happens either consciously or unconsciously. The general processing of information influences behaviour and feelings.
The theory of perception
While feelings are a physical reaction to external influences, the significance of the information received depends on the individual's perception. Changes in the body perceive certain situations as significant and the person reacts to them in a way that we call feelings.
The theory of affect-related events
Most scientists agree that emotions are based on communication with the environment. This theory assumes that certain events trigger certain physical reactions, which in turn influence inner attitudes and behaviour.
