They developed several laws and principles to describe human experiences and perceptions. The cognitive movement was pioneered by the works of Chomsky and Piaget and focused on the role of cognition in relation with the outer environment (which provides input for information processing) and behavior.
The most important findings so far regard the components of visual perception, the most important stages of development (according to Piaget), how do most of our complex mental processes work (for instance memory, attention, decision-making etc.), how do processes like the orienting response, habituation, classical conditioning, operant conditioning, and imitation influence behavior, how does the speech develop, the components of an emotional reaction, the relationship between cognition and emotion, how does the infant attachment develop and what impact it has on adult life, how the concepts of self-concept, self-awareness develop, the concept of self-esteem, the different temperamental types and personality etc.
This multitude of problems has been studied with diverse methodologies and from varied perspectives: humanistic, psychoanalytic, existentialist, cognitive, behavioral to mention only the most important of them. The various approaches and methodologies led to specific applied fields in psychology, as already mentioned above.
The fields of research usually embrace a specific scientific paradigm.
However, the complexity of the psychological science cannot be neglected. In almost two centuries of existence it has made great progress. The future of psychology lies especially in explaining how mind, the brain, other biological systems of the body, and human environments interact to produce behavior. An important question to be answered concerns the role of the unconscious and the concept of cognitive unconscious deserves further research. A great impact on psychology has been made from the part of biology and computer science. Therefore, the scope and methods of research have also changed suggesting new areas such as electronic communication, electronic learning etc.
