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...)

Reading is an important means through which children develop their vocabulary.

Vocabulary development is a process by which people acquire words. Babbling shifts towards meaningful speech as infants grow and produce their first words around the age of one year. In early word learning, infants build their vocabulary slowly. By the age of 18 months, infants can typically produce about 50 words and begin to make word combinations.

In order to build their vocabularies, infants must learn about the meanings that words carry. The mapping problem asks how infants correctly learn to attach words to referents. Constraints theories, domain-general views, social-pragmatic accounts, and an emergentist coalition model have been proposed to account for the mapping problem. (Full article...)

Phyllis Chesler (born October 1, 1940) is an American writer, psychotherapist, and professor emerita of psychology and women's studies at the College of Staten Island (CUNY). She is a renowned second-wave feminist psychologist and the author of 18 books, including the best-sellers Women and Madness (1972), With Child: A Diary of Motherhood (1979), and An American Bride in Kabul: A Memoir (2013). Chesler has written extensively about topics such as gender, mental illness, divorce and child custody, surrogacy, second-wave feminism, pornography, prostitution, incest, and violence against women.

Chesler has written several works on subjects such as anti-Semitism, women in Islam, and honor killings. Chesler argues that many Western intellectuals, including leftists and feminists, have abandoned Western values in the name of multicultural relativism, and that this has led to an alliance with Islamists, an increase in anti-Semitism, and to the abandonment of Muslim women and religious minorities in Muslim-majority countries.
