Naiser published cognitive psychology in 1967, which marked the emergence of cognitive psychology, which was the fourth and most fatal impact on behaviorism. Since then, cognitive psychology has become a banner in psychology, calling and guiding more psychologists to leave behaviorism and turn to cognitive research. Psychology has also entered a new era.

Ulrich Gustav Neisser (1928-2012) was born in Kiel, Germany. In 1933, he immigrated to the United States with his family. Naiser's father is a famous economist. He wants naiser to become a scientist. When naiser entered Harvard University, he found that psychology was more interesting than physics and was attracted by Gestalt psychology. This school holds a complex and comprehensive view of psychological process, but the scientific rigor is not enough. Naiser has done research on super sensory perception, of course, without success. Nathan received an undergraduate degree in psychology from Harvard University, a master's degree from Swarthmore College and a doctorate from Harvard University. He taught and did research at Brandeis University, Cornell University and Emory University.

After the Second World War, the progress of information theory, computer and experimental methods enabled scientists to challenge the mainstream psychology behaviorism. Behaviorism examines the stimulation of the senses and the resulting response. In its purest thought, behaviorism rejects the view of mental existence. For example, Skinner's psychology is empty box psychology, regardless of the process in the brain.

With the development of computer technology in the 1960s, scholars studying mind began to imagine mind as an information processing system. Chomsky put forward a new linguistic theory, which assumes that the mind has a congenital structure. Nasser integrated these new studies to construct a new view of mind, thinking about how the brain works in a coherent way.

Nasser tries to prove that people can think and describe how people think. In 1967, he named this new field cognitive psychology with the title of his book, and expounded an important point: the internal psychological process is not only important, but also can be studied and measured.

Naiser's research shows that memory is the reconstruction of the past, not the photographing of the past. He found that although many people think they remember real events, they actually remember only the content they constructed.

The day after the American space shuttle Challenger exploded in 1986, naiser asked students to write down their direct experience after hearing the news. About three years later, he asked the students to repeat it. The results show that 1 / 4 of the restatements are very different from the original, 1 / 2 of the restatements are different, and less than 1 / 10 of the restatements write all the details correctly. In particular, these subjects were convinced that their later description was completely accurate.

In a perceptual experiment, naiser asked subjects to watch videos of different groups pitching on the screen. While the subjects were watching, a woman walked through the room with an umbrella. The results showed that few subjects remembered seeing her. Naiser calls this phenomenon selective viewing, and other psychologists call it inattentive blindness. Similarly, our people have long discovered this phenomenon, and there is an idiom - turning a blind eye.

In the 1980s, there was a case in the United States in which an adult woman sued her father and stated that she encountered sexual assault from her father when she was young. Once the case was reported, it triggered a wave of childhood abuse cases across the United States, and more adult women sued their fathers. At that time, it was widely held that the women's extremely vivid memory could not be wrong. Sennai's perception and memory experiment questioned the authenticity of such cases. The personal experience and experimental research of lovtas, another psychologist, also shows that people's false memory is very common.

In 1995, sennai led a special group of the American Psychological Society to investigate studies that showed that people of different races had different intelligence. The team eventually questioned the studies themselves, because the corresponding studies would make the hypothesis that children with low intelligence test scores have problems. Once the researcher makes this assumption, his / her subsequent theory and research will have internal bias. This is a very important research deviation problem.

In short, naiser integrated research and ideas in related fields, investigated psychological processes such as perception and memory, and made outstanding contributions to the emergence of cognitive psychology. At the same time, he pays attention to the needs of social reality and is committed to solving real problems. Therefore, his research work has both theoretical value and practical significance. In particular, his experimental research is not only innovative, but also vivid and interesting.
