Answer:
How is human behavior formed?
Human behavior is formed (or influenced) by a few separate factors - internal dialogue, biological (genetics) and environmental stimulations.
Environmental: This entails what goes on in your immediate surroundings throughout your childhood and adulthood. Home and school typically make up the most in terms of environmental influence.
In example, an abusive household raises the likelihood of you being in the same situation later in life. A meticulously clean household does the same - see internal dialogue. The environment that surrounds us does not set in stone how we will be when we are older, but it does have a great impact.
You can subconsciously be influenced by a friend or a passerby as well, without knowing in the moment that the things they say will impact your future choices. Your parents can for example, be completely against homosexuals and so you agree... until you read a book or meet someone in which their opinion defers.
Biological: Around 17%-23% of people suffer from a mental disorder that have genetic causations, from psychophrenia to bipolar disorder, these are uncontrollable and often require medication in order to live a fully functioning life. Alcoholism is also a good example of a biological influence, if we have alcoholic parents we are genetically predisposed to repeating the pattern.
Internal dialogue: This is, in a sense, how you speak to yourself. When angry, do you lash out first and ask questions later? When approached with a difficult choice, we have a moment were we ask ourselves - what do I do next? I suppose that this isn't an influence itself but it's the force between our environmental and biological influences throughout life... it's what keeps every person from being the exact same. There are a thousand things that will overall develop your behaviours, but this is the most important to remember - how you handle them and what you take from it.
