A person's attitude toward a person, place or thing influences that person's decisions, actions or behaviors toward the person, place or thing. Someone who doesn't like a particular person, for instance, is likely to act with rudeness, aggressiveness or disinterest toward that person.
A general negative attitude, or pessimism, tends to cause a person to have less-productive relationships and to act in less-beneficial ways. An optimist, or someone with a generally positive attitude, tends to set goals, take productive actions and work through obstacles. Emotional reactions to certain triggers are also behaviors affected by someone's attitude. Resentment toward a parent, for example, can cause quick anger or sadness during an exchange.
