Psychology is the scientific study of the mind and behavior. Its subject matter includes the behavior of humans and nonhumans, both conscious and unconscious phenomena, and mental processes such as thoughts, feelings, and motives. Psychology is an academic discipline of broad scope, crossing the boundaries between the natural and social sciences.

A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some psychologists attempt to understand the role of mental functions in individual and social behavior. Others explore the physiological and neurobiological processes that underlie cognitive functions and behaviors. Biological psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.


As part of an interdisciplinary field, psychologists are involved in research on perception, cognition, attention, emotion, intelligence, subjective experiences, motivation, brain functioning, and personality. Psychologists' interests extend to interpersonal relationships, psychological resilience, family resilience, and other areas within social psychology. They also consider the unconscious mind. Research psychologists employ empirical methods to infer causal and correlational relationships between psychosocial variables. Some, but not all, clinical and counseling psychologists rely on symbolic interpretation. (Full article...)

Sorrowing Old Man (At Eternity's Gate)

Major depressive disorder (MDD), also known as clinical depression, is a mental disorder characterized by at least two weeks of pervasive low mood, low self-esteem, and loss of interest or pleasure in normally enjoyable activities. Introduced by a group of US clinicians in the mid-1970s, the term was adopted by the American Psychiatric Association for this symptom cluster under mood disorders in the 1980 version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III), and has become widely used since. The disorder causes the second-most years lived with disability, after lower back pain.

The diagnosis of major depressive disorder is based on the person's experiences, and behavior reported by family or friends, and a mental status examination. There is no laboratory test for the disorder, but blood testing and similar may be done to rule out physical conditions that can cause similar symptoms. The most common time of onset is in a person's 20s. Men are much less likely to report than women, with approximately 33.2% of men and 43.0% of women with depressive symptoms reporting seeking help, possibly due to pressures of masking for men. The course of the disorder varies widely, from one episode lasting months to a lifelong disorder with recurrent episodes. (Full article...)

Ellis c. 1966

Albert Ellis (September 27, 1913 – July 24, 2007) was an American psychologist and psychotherapist who founded rational emotive behavior therapy (REBT). He held MA and PhD degrees in clinical psychology from Columbia University, and was certified by the American Board of Professional Psychology (ABPP). He also founded, and was the President of, the New York City-based Albert Ellis Institute. He is generally considered to be one of the originators of the cognitive revolutionary paradigm shift in psychotherapy and an early proponent and developer of cognitive-behavioral therapies.

Based on a 1982 professional survey of American and Canadian psychologists, he was considered the second most influential psychotherapist in history (Carl Rogers ranked first in the survey; Sigmund Freud was ranked third). Psychology Today noted that, "No individual—not even Freud himself—has had a greater impact on modern psychotherapy." (Full article...)
