About Psychologist Speciality

Psychologist, in simpler terms is a scientist who is trained in psychology. Psychology is as vast as the human mind. This field deals with multiple sections of the human brain. It is defined as the scientific study of perception, attention, emotion, motivation, personality, behaviour and interpersonal relationships. In some cases, even the unconscious mind becomes a part of the study. As psychology deals with just more than one aspect of human behaviour, there are people who specialize in different fields of psychology. The common ones are clinical psychology, counselling psychology, school psychology, forensic psychology, health psychology, neuropsychology, industrial-organizational psychology, developmental psychology and research psychology.
Psychologists coordinate with adults, adolescents, and children, addressing common problems such as depression, anxiety and substance abuse. They also work in schools to help students enhance learning. Psychologists consult with and provide expert testimony in court proceedings.
