it seemed to connote arrogance and be a negative attribute). In 1890, the philosopher William James in his Principles of Psychology wrote, "Believe what is in the line of your needs, for only by such belief is the need fulfilled ... Have faith that you can successfully make it, and your feet are nerved to its accomplishment," expressing how self-confidence could be a virtue. That same year, Dr. Frederick Needham, in his presidential address to the opening of the British Medical Journals Section of Psychology praised a progressive new architecture of an asylum accommodation for insane patients as increasing their self-confidence by offering them greater "liberty of action, extended exercise, and occupation, thus generating self-confidence and becoming, not only excellent tests of the sanity of the patient, but operating powerfully in promoting recovery." With the arrival of World War I, psychologists praised self-confidence as greatly decreasing nervous tension, allaying fear, and ridding the battlefield of terror; they argued that soldiers who cultivated a strong and healthy body would also acquire greater self-confidence while fighting. At the height of the Temperance social reform movement of the 1920s, psychologists associated self-confidence in men with remaining at home and taking care of the family when they were not working. During the Great Depression, Philip Eisenberg and Paul Lazerfeld noted how a sudden negative change in one's circumstances, especially a loss of a job, could lead to decreased self-confidence, but more commonly if the jobless person believes the fault of his unemployment is his. They also noted how if individuals do not have a job long enough, they became apathetic and lost all self-confidence. In 1943, Abraham Maslow in his paper "A Theory of Human Motivation" argued that an individual is only motivated to acquire self-confidence (one component of "esteem") after achieving what they need for physiological survival, safety, and love and belonging. He claimed that satisfaction of self-esteem led to feelings of self-confidence that, once attained, led to a desire for "self-actualization." As material standards of most people rapidly rose in developed countries after World War II and fulfilled their material needs, a plethora of widely cited academic research about-confidence and many related concepts like self-esteem and self-efficacy emerged. Theories and correlations with other variables and factors Self-confidence as an intra-psychological variable Social psychologists have found self-confidence to be correlated with other psychological variables within individuals, including saving money, influencing others, and being
