The birth of cognitive science dates back to the 1950s, a decade that saw the redefinition of the fields of psychology, anthropology, and linguistics, as well as the emergence of computer science and neuroscience. Psychology had to break away from behaviorism and give scientific cognition validity before it could enter the cognitive revolution.
Also popular as cognitive movement, the cognitive revolution in psychology was a counterrevolution. The first revolution happened much earlier when a group of experimental psychologists wanted to reframe psychology as the science of behavior. They were influenced by Pavlov and other physiologists of the time. They claimed that people could not properly observe mental processes. The only reliable evidence is behavioral, and it must be behavioral. By shifting its focus to the study of behavior, psychology could develop into an impartial discipline based on behavioral science. Today's psychologists have seen a resurgence of interest in cognitive psychology, which is seen as a rebellion against behaviorism. In general, cognitive psychologists are interested in understanding how stimuli influence behavior. They presume that specific cognitive or mental processes occur between the two.
Developments in domains like computer science and linguistics, as well as certain previous works in philosophy and psychology, have all impacted cognitive psychology. Following are some of the main antecedent forces of contemporary cognitive psychology.
According to the philosophical notion of empiricism, all human knowledge comes from sensory experience. Empiricism is a school of epistemology that rejects the idea of intuitive conceptions and places its whole emphasis on sensory experience and evidence. Empiricism is a philosophical system that claims sensory experience is the only (or primary) source of knowledge. As a result, it disapproves of using theoretical reasoning in knowledge acquisition and analysis. It competes with rationalism, which holds that reasoning is the best way to learn anything. In his essay An Essay Concerning Human Understanding, John Locke introduced the empiricism school of thought. According to Locke, experience is the primary means by which people may learn new things. According to Locke, humans cannot create or have inborn ideas.
In response to empiricism, nativism is a view of human cognition with a long and rich history in philosophy. Even today, many people believe that nativism is an important part of how we explain human nature.
One of the first schools of philosophy, structuralism, is defined as the study of the constituents of consciousness. Basic components are based on an introspective technique and derive from each conscious experience. According to this introspection technique, every conscious experience must be expressed in the most basic terms possible. Several major problems with Wundt's conclusions have come to light since they were published, which in turn clash with current psychological research. It has been questioned whether Wundt's observations can be trusted. Wundt considered any gaps in the observation when training his observers and trainees.
According to Tolman, several intermediary variables exist between the input (stimulus) and the output (learned behavior), including expectancies, signs, cognitive maps, etc. Based on Tolman's perspective, contemporary cognitive psychologists have strongly emphasized describing the relationship between the input (environment) and the output (the resulting behavior). These cognitive psychologists, like Tolman, have strongly emphasized the intermediate cognitions that eventually result in certain behavior. Another significant cognitive behaviorist was Bandura, whose emphasis on cognition and self-reinforcement helped steer the development of cognitive psychology in the proper direction.
Like structuralist psychologists who utilized controlled introspection in sensory tests, gestalt psychologists strongly emphasized the study of consciousness. However, they underlined that the world, as experienced and perceived (Gestalten), is already whole with structures. They disagreed with the structuralist and associationist theories claiming that consciousness comprises associated components. Later Gestaltists embraced behavioral wholes rather than progressive learning through trial and error, as shown by the example of an ape using insight to combine two bamboo stalks to reach a banana. Despite emphasizing awareness, they assumed isomorphism and connected it to the brain. However, by the middle of the 20th century, Gestalt social psychology had built a bridge between experiments and social activity. In contrast, classical Gestalt relied mainly on the single demonstration or experimentum crucis. The relevance of the so-called Gestalt flip in terms of realism versus relativism was a topic of discussion among scientists and philosophers of science. This raises questions regarding the tenets of scientific reality when paradigms shift. As a result, the development of cognitive psychology was gradual, and its foundations were found in the ideas presented by major psychological systems.
George A. Miller, one of the pioneers of cognitive psychology, was the first to recognize that an information-processing model can explain how the human mind functions. His contributions enabled psychology study to advance beyond the behaviorist approaches that predominated until the 1950s. He received the National Medal of Science in 1991 for his major contributions to psychology.
Jean Piaget studied children's cognitive development. He believed that children often have distinct thought processes from adults. He classified the stages of cognitive development: as sensorimotor, preoperational, concrete operational, and formal operational. According to him, age determines what stage a person is in, and each of these stages often involves a distinct type of intellect. During these stages, intelligence develops both quantitatively and qualitatively.

Chomsky is a linguist who initially drew psychologists' attention when writing a critical assessment of Skinner's book "Verbal Behavior," followed by another critical review of Skinner's Beyond freedom and dignity. He criticized Skinner's operant conditioning theory regarding verbal behavior or language.
Cognitive psychology is a response against behaviorism, which is perceived to be excessively narrow in its approach. Cognitive psychologists have noted that behavioristic explanations can only explain elementary human behaviors in terms of stimulus input and response output. Examining a person's many internal mental processes is crucial for comprehending complex behaviors. Cognitive psychology is an effort to look into all those mental operations differently than the old-school structuralists did. A cognitive psychologist strives to investigate such mental processes with greater objectivity and science.
