For example, if a woman was given the self-relevant stimuli of female and mother, psychologists would measure how quickly she identified the negative word, evil, or the positive word, kind. Development across lifespan
Experiences in a persons life are a major source of how self-esteem develops. In the early years of a childs life, parents have a significant influence on self-esteem and can be considered the main source of positive and negative experiences a child will have. Unconditional love from parents helps a child develop a stable sense of being cared for and respected. These feelings translate into later effects on self-esteem as the child grows older. Students in elementary school who have high self-esteem tend to have authoritative parents who are caring, supportive adults who set clear standards for their child and allow them to voice their opinion in decision making. Although studies thus far have reported only a correlation of warm, supportive parenting styles (mainly authoritative and permissive) with children having high self-esteem, these parenting styles could easily be thought of as having some causal effect in self-esteem development. Childhood experiences that contribute to healthy self-esteem include being listened to, being spoken to respectfully, receiving appropriate attention and affection and having accomplishments recognized and mistakes or failures acknowledged and accepted. Experiences that contribute to low self-esteem include being harshly criticized, being physically, sexually or emotionally abused, being ignored, ridiculed or teased or being expected to be "perfect" all the time.During school-aged years, academic achievement is a significant contributor to self-esteem development.
They may also try to blame others to protect their self-image from situations that would threaten it. They may employ defense mechanisms, including attempting to lose at games and other competitions in order to protect their self-image by publicly dissociating themselves from a need to win, and asserting an independence from social acceptance which they may deeply desire. In this deep fear of being unaccepted by an individuals peers, they make poor life choices by making risky decisions. Strong
People with strong self-esteem have a positive self-image and enough strength so that anti-feats do not subdue their self-esteem. They have less fear of failure. These individuals appear humble, cheerful, and this shows a certain strength not to boast about feats and not to be afraid of anti-feats. They are capable of fighting with all their might to achieve their goals because, if things go wrong, their self-esteem will not be affected. They can acknowledge their own mistakes precisely because their self-image is strong, and this acknowledgment will not impair or affect their self-image. They live with less fear of losing social prestige, and with more happiness and general well-being. However, no type of self-esteem is indestructible, and due to certain situations or circumstances in life, one can fall from this level into any other state of self-esteem. Contingent vs. non-contingent
A distinction is made between contingent (or conditional)  and non-contingent (or unconditional) self-esteem. Contingent self-esteem is derived from external sources, such as what others say, ones success or failure, ones competence, or relationship-contingent self-esteem.
