The Psychological Portal


Psychology (Greek: ψυχολογία) is the academic and applied study of behavior, mind, and their underlying mechanisms. It primarily applies to humans but can also be applied to non-humans such as animals or artificial systems. Psychology also refers to the application of such knowledge to various spheres of activity, including problems of human beings' daily lives and the treatment of mental illness. The field contains a range of sub-areas (for instance, the studies of development, personality, and language), as well as many different theoretical orientations (such as behaviorism, evolutionary psychology, and psychoanalysis). Psychology draws from a number of other fields of study, including biology, sociology, anthropology, and philosophy.

An illustration of schizophrenia's effect on the brain
Schizophrenia is a psychiatric diagnosis that describes a mental disorder characterized by impairments in the perception or expression of reality and by significant social or occupational dysfunction. A person experiencing untreated schizophrenia is typically characterized as demonstrating disorganized thinking, and as experiencing delusions or auditory hallucinations.

Although the disorder is primarily thought to affect cognition, it can also contribute to chronic problems with behavior and emotion. Due to the many possible combinations of symptoms, heated debate is ongoing about whether the diagnosis necessarily or adequately describes a disorder, or alternatively whether it might represent a number of disorders. For this reason, Eugen Bleuler deliberately called the disease "the schizophrenias" plural, when he coined the present name.

The Scream
The Scream (Skrik, 1893) is a seminal series of expressionist paintings by Norwegian artist Edvard Munch. It is said by some to symbolize the human species taken by an attack of existential angst, with the skyline inspired by the red twilights seen after the 1883 eruption of Krakatoa.

Angst is a Dutch, German, and Scandinavian word for fear or anxiety. It is used in English to describe an intense feeling of emotional strife.

Jean Piaget
Jean Piaget was a Swiss philosopher, natural scientist and developmental psychologist, well known for his work studying children, his theory of cognitive development and its impact on constructivism-based pedagogy.

Piaget served as professor of psychology at the University of Geneva from 1929 to 1975 and is best known for reorganizing cognitive development theory into a series of stages, expanding on earlier work from James Mark Baldwin: four levels of development corresponding roughly to (1) infancy, (2) pre-school, (3) childhood, and (4) adolescence.
