Many texts define psychology as the "science of mental processes and behavior." Psychology is difficult to define because the word "mental" suggests there are no boundaries or limits. "Psyche", in "Psychology," also suggests breath, life, soul or mind -- all of which are without limit. Subfields of Psychology

A psychologist also develops, gives and interprets tests of mental abilities, aptitudes, interests, personality characteristics and motivations.
Only licensed psychologists may practice psychology with private patients without supervision. To get a license, the individual must have an appropriate doctorate degree, work in the psychology field under supervision for two years, and pass the National written exam.
Decide what area you want help with, i.e. your children, spouse, substance abuse, depression, stress, etc. Then begin looking for a psychologist trained in that area. Ask friends or relatives for recommendations. Also check with your health insurance company for a list of authorized providers. You can call the national, state and local psychological associations for referrals. When you have a list of possibilities, you can narrow it down by determining if gender or geographical location makes a difference to you. Next, meet with the psychologist to see if the two of you are compatible. It is important that you feel comfortable with the psychologist.
