Psychology is the scientific study of 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 immense scope, crossing the boundaries between the natural and social sciences. 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.

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.


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...)

Le Suicidé, c. 1877

Suicide is the act of intentionally causing one's own death. Mental disorders (including depression, bipolar disorder, schizophrenia, personality disorders, anxiety disorders, attention deficit hyperactivity disorder, and cognitive disengagement syndrome), physical disorders (such as chronic fatigue syndrome), and substance abuse (including alcoholism and benzodiazepine use and withdrawal) are risk factors.

Some suicides are impulsive acts driven by stress (such as from financial or academic difficulties), relationship problems (such as breakups or divorces), or harassment and bullying. Those who have previously attempted suicide are at a higher risk for future attempts. Effective suicide prevention efforts include limiting access to methods of suicide such as firearms, drugs, and poisons; treating mental disorders and substance abuse; careful media reporting about suicide; improving economic conditions; and dialectical behaviour therapy (DBT). Although crisis hotlines, like 988, are common resources, their effectiveness has not been well studied. (Full article...)

Søren Aabye Kierkegaard (/ˈsɒrən ˈkɪərkəɡɑːrd/ SORR-ən KEER-kə-gard, US also /-ɡɔːr/ -⁠gor; Danish: [ˈsɶːɐn ˈɔˀˌpyˀ ˈkʰiɐ̯kəˌkɒˀ] ; 5 May 1813 – 11 November 1855) was a Danish theologian, philosopher, poet, social critic, and religious author who is widely considered to be the first Christian existentialist philosopher. He wrote critical texts on organized religion, Christianity, morality, ethics, psychology, and the philosophy of religion, displaying a fondness for metaphor, irony, and parables. Much of his philosophical work deals with the issues of how one lives as a "single individual", giving priority to concrete human reality over abstract thinking and highlighting the importance of personal choice and commitment.

Kierkegaard's theological work focuses on Christian ethics, the institution of the Church, the differences between purely objective proofs of Christianity, the infinite qualitative distinction between man and God, and the individual's subjective relationship to the God-Man Jesus the Christ, which came through faith. Much of his work deals with Christian love. He was extremely critical of the doctrine and practice of Christianity as a state-controlled religion (Caesaropapism) like the Church of Denmark. His psychological work explored the emotions and feelings of individuals when faced with life choices. Opposite Jean-Paul Sartre and the atheistic existentialism paradigm, Kierkegaard focused on Christian existentialism. (Full article...)
