Wilhelm Wundt is considered the “father of experimental psychology.” His psychological laboratory at the University of Leipzig was the first of its kind. It is because of his efforts that psychology is considered a distinct scientific discipline.

Maslow and Rogers theorized that what an individual chooses to believe and accept to be true determines the likelihood of developing certain psychological disorders. This is a humanistic way of thinking. 

Erik Erikson was a developmental psychologist who is famous for developing the psychosocial stages of development, each of which involved a conflict or crisis between the wants of the individual and the wants of the society, such as trust vs. distrust in infancy.

Jean Piaget was a developmental psychologist who is famous for developing a cognitive theory of development, which centered around figuring out why and how people (particularly children) make mistakes as a way of figuring out their ways of thinking. Based on that research, Piaget came up with stages of cognitive development—sensorimotor, pre-operational, concrete operational, and formal operational.

Lawrence Kohlberg was a developmental psychologist who is famous for developing stages of moral development based on the perceived consequences for the actor—pre-conventional (based on immediate consequences), conventional (authority-focused), and post-conventional (based on individual morals).

Abraham Maslow is a psychologist famous for his theory of hierarchy of needs, which explains the order in which humans prioritize their desires. The hierarchy goes from physical needs to safety to love/belonging to esteem to self-actualization.

Stanley Milgram is a social psychologist who is famous for his experiments on obedience to authority, which are now known as “the Milgram experiments.” These experiments involved subjects giving an electric shock (or so they thought) to another subject because an authority figure demanded it. The willingness of people to go against their conscience to obey authority was surprising and an important discovery.

Carl Rogers was a humanistic psychologist who is most famous for the development of client-centered therapy, a type of therapy that involves clients trying to reach self-realization themselves (rather than being told answers by the therapists) and the therapist treating the client with unconditional positive regard.

William Wundt was a psychologist who is considered by some to be the father of psychology because he started to separate psychology from philosophy by showing that psychology, like other branches of science, can use the experimental method to get empirical results. Wundt also focused his research on introspection and structuralism, which is the study of the different components of the mind.

Philip Zimbardo is a psychologist most famous for the “Stanford Prison Experiment” in which a group of male subjects were randomly assigned to be either prison guards or inmates. The study found that after only a few days, the prison guards were sadistic and the inmates desolate, indicating how strongly people respond to situational factors.

Noam Chomsky is a cognitive psychologist and linguist who is most famous for his nativist theory of language. This theory rests on a critique of Skinner’s idea that language is learned through conditioning and instead suggests that children are born with a language acquisition device that allows them to learn language from birth.

Benjamin Lee Whorf is a cognitive linguist who is most famous for his idea that the language you speak affects the way that you view and think about the world, otherwise known as linguistic relativity or the Sapir-Whorf hypothesis.
