The five major theoretical perspectives in psychology are biological, learning, cognitive, psychodynamic, and sociocultural perspectives. Each one of these perspectives searches for answers about behavior through different techniques and through looking for answers to different kinds of questions. Due to the different approaches, each perspective form their own assumptions and explanations. Some perspectives are widely accepted while others struggle for acceptance.
"The premise behind the biological perspective in psychology is that all actions, feelings, and thoughts are associated with bodily events." Biological psychologists examine how all of the electrical impulses, hormones, and chemicals flowing through the body can effect behavior and how changes to these bodily functions can change behavior. They are concerned with how the aspects of biology effect peoples' emotions, learning abilities, and their perception of events.
One of the major theories of biological psychology is that "We cannot know ourselves if we do not know our bodies." Through application of this theory, biological psychologists strive to understand the relationship between the mind and body and they influence sickness or health. It is believed that poor health can lead to negative attitudes while poor attitudes can lead to poor health. Biological psychologists research and study the correlation of this theory in an attempt to help solve some mental and emotional problems.
Learning Perspective
The writings and findings of Ivan Pavlov, John B. Watson, and B.F. Skinner have done much for the advancement of modern psychology. Many of the important findings in psychology from their theory of behaviorism, later evolving into the social-learning theory or cognitive social-learning theory. Proponents of the learning perspective think that mentalism should be abandoned for behaviorism. Psychologists should concentrate on observation and direct measurement rather focusing on introspection.
Behaviorists believed that actions were responses to stimuli that were learned. The basic concept was that positive responses would be triggered by good stimuli while negative responses would could from bad stimuli. Actions that would produce positive results tended to repeated, while those that led to negative results tended to be avoided.
This concept led to a broadening of psychology. Many groups that were often overlooked by psychologists were being discovered and observed. Behavior became the dominant school of psychology in the U.S. until the 1960's.
Adversaries to this approach were repulsed by the concept that humans did not think or feel, but only thought that they did. Nonbehaviorists and behaviorists parted company. Behaviorists believed that feelings could not explain behavior. Out of behaviorism came the social learning theory, which taught that in addition to behavior, imitation and observation led to learning.
Cognitive Perspective
The cognitive perspective of psychology focuses on the thought process. Psychologists from this school argue that it is necessary to know what is going on in the mind to fully understand why a person will do the things that they do. By observing behavior, psychologists try to interpret what thought process led to the action. Critics who disapprove of this theory do so on the basis that in addition to perceptions, external forces must also be taken into consideration.
The objective of cognitive psychology is to understand how perceptions and interpretations relate to behavior. Why ...
