WHAT IS PSYCHOLOGY?To be human is to be curious about ourselves and the world around us. Psychology.s ancestors therefore date to the world.s early writings. Before 300 B.C., the Greek naturalist and philosopher Aristotle theorized about learning and memory, motivation and emotion, perception and personality. Today we chuckle at some of his guesses, like a meal making us sleepy by causing gas and heat to collect around the source of our personality, the heart. But credit Aristotle with asking the right questions. At the dawn of modern science in the 1600s, British philosophers adopted a down-to-earth approach to knowledge, rooted in observation. Thinking about thinking continued to evolve until the birth of psychology as we know it, on a December day in 1879. In a small room on the third floor of a shabby building at Germany.s University of Leipzig, two young men were helping a long-faced, austere, middleaged professor, Wilhelm Wundt, create an experimental apparatus. Wundt was seeking to measure the .atoms of the mind. . the fastest and simplest mental processes. Thus began what many consider psychology.s first experiment, launching the first psychological institute, staffed by Wundt and psychology.s first graduate students. The young science of psychology thus evolved from the more established fields of biology and philosophy. Wundt was both a physiologist and a philosopher. Darwin was an English naturalist. Ivan Pavlov, who pioneered the study of learning, was a Russian physiologist. Sigmund Freud, renowned personality theorist, was an American physician. So what is psychology? With activities ranging from recording nerve-cell activity to psychotherapy, psychology is not easily defined. Psychology began as the science of mental life. Wundt.s basic research tool became introspection . self-examination of one.s own emotional states, feelings, and thoughts. Thus, until the 1920s, psychology was defined as .the science of mental life. Let.s unpack this definition. Behavior is anything an organism does . any action we can observe and record. Yelling, smiling, blinking, sweating, talking, and questionnaire-making are all observable behaviors. Mental processes are the internal subjective experiences we infer from behavior . sensations, perceptions, dreams, thoughts, beliefs, and feelings. For many psychologists, the key word in psychology.s definition is science. Psychology is less a set of findings than a way of asking and answering questions. As a science psychology aims to sift opinions and evaluate ideas with careful observation and rigorous analysis. In its quest to describe and explain nature (human nature included), psychological science welcomes hunches and plausible-sounding theories. And it puts them to the test. Date: 2015-01-29; view: 1925
