The history of professional psychology is marked by a variety of approaches and perspectives. These are distinct ways of observing and analyzing human behavior and thought processes. Students earning a psychology degree are often curious about which perspective is correct. The truth is that no approach is necessarily better or more accurate than the others. Show In fact, psychologists may embrace multiple perspectives, as each perspective has strengths and weaknesses. Understanding a variety of psychological perspectives can help students and professionals develop a more comprehensive view of mental health and developmental issues. The Biological PerspectiveThe biological perspective is also known as biopsychology or physiological psychology. Biopsychology focuses on the physical and biological roots of behavior. For example, a biological psychologist may research the influence of genetics on behavior or the changes in personality after a person suffers damage to certain parts of the brain. This type of research also explores the physiological effects of drugs and diseases on patients. Diagnostic tools, such as positron emission tomography (PET) and magnetic resonance imaging (MRI) scans, play a vital role in biological psychology. The findings of biological psychologists are often useful in discovering new treatments. For example, a biological psychologist may determine that the level of dopamine in the brain plays a significant role in schizophrenia. This could influence research to test new drugs intended to stabilize dopamine levels in schizophrenia patients. The Cognitive PerspectiveCognitive psychology stands in stark contrast to behavioral psychology. This approach focuses on how internal thoughts and feelings influence one’s behavior. The cognitive approach emphasizes the importance of memory, perception and attention, language, decision-making and problem-solving. This approach often compares the human mind to that of a computer. It states that human memory is comprised of three stages:
Cognitive psychology seeks to understand why people learn and process information the way they do. Cognitive psychologists might help patients cope with memory disorders, or they might consult on ways to improve educational environments and curriculum. The Behavioral PerspectiveThe behavioral perspective gained popularity during the early 1900s with groundbreaking work by John B. Watson and Edward Thorndike.* This approach centers around learned behaviors rather than internal processes like cognition. In other words, behavioral psychologists explore psychology through observable behaviors and actions. In this perspective, psychologists treat all behavior as learned or acquired. For example, a researcher could conclude that an introverted behavior pattern was acquired in response to childhood rejection by peers during attempts at interaction. The Humanistic PerspectiveThe humanistic perspective, due to work by notable thinkers like Abraham Maslow and Carl Rogers, arose during the 1950s. Humanistic psychology focuses on the importance of helping people achieve their full potential for well-being. Instead of focusing on abnormal psychology, the humanistic perspective emphasizes free will, self-actualization and self-efficacy. Before the development of this approach, the psychology profession was dominated by the behavioral and psychodynamic approaches. Some psychologists critiqued these approaches as deterministic and pessimistic. Some of the central principles of the humanistic perspective are:
The Psychodynamic PerspectiveSigmund Freud (1856-1939) founded the psychodynamic perspective. Freud believed that human beings possess little free will. Rather, the behaviors exhibited by adults result from their childhood experiences and the contents of their subconscious mind. An analogy Freud used to explain the subconscious mind is the iceberg. Only a small part of a floating iceberg is visible above the water. Most of the iceberg is underneath the water. In Freud's analogy, the tip of the iceberg represents the conscious mind. The conscious mind makes up only a small percentage of a person’s thought processes. A second, larger layer is the subconscious mind. The subconscious mind consists of thoughts that a person could retrieve with effort. The last and deepest layer is the unconscious mind. The unconscious mind consists of thoughts that a person is unaware of. Even with effort, people are unable to become aware of unconscious thought processes. The psychodynamic perspective theorizes that the subconscious mind influences behaviors. A person can overcome undesirable behaviors and thoughts by forming a better understanding of their subconscious root causes. As a result, “talk therapy,” or “the talking cure,” was developed to guide patients to a better understanding of their internal processes. There are benefits to taking a page from some or all these schools of thought in psychology. Psychologists can form regimens that use different a combination of psychological perspectives to offer a diverse understanding and practice.

Psychologists today do not believe there is one "right" way to study the way people think or behave. There are, however, various schools of thought that evolved throughout the development of psychology that continue to shape the way psychologists investigate human behavior. For example, some psychologists might attribute a certain behavior to biological factors such as genetics while another psychologist might consider early childhood experiences to be a more likely explanation for the behavior. Because psychologists might emphasize various points within psychology in their research and analysis of behavior, there are different viewpoints in psychology. These schools of thought are known as approaches, or perspectives. Link to Learning: Review the five main psychological perspectives found HERE. Psychodynamic theory is an approach to psychology that studies the psychological forces underlying human behavior, feelings, and emotions, and how they may relate to early childhood experience. This theory is especially interested in the dynamic relations between conscious and unconscious motivation, and asserts that behavior is the product of underlying conflicts over which people often have little awareness. Psychodynamic theory was born in 1874 with the works of German scientist Ernst von Brucke, who supposed that all living organisms are energy systems governed by the principle of the conservation of energy. During the same year, medical student Sigmund Freud adopted this new "dynamic" physiology and expanded it to create the original concept of "psychodynamics," in which he suggested that psychological processes are flows of psychosexual energy (libido) in a complex brain. Freud also coined the term "psychoanalysis." Later, these theories were developed further by Carl Jung, Alfred Adler, Melanie Klein, and others. By the mid-1940s and into the 1950s, the general application of the "psychodynamic theory" had been well established.
Freud's theory of psychoanalysis holds two major assumptions: (1) that much of mental life is unconscious (i.e., outside of awareness), and (2) that past experiences, especially in early childhood, shape how a person feels and behaves throughout life. The concept of the unconscious was central: Freud postulated a cycle in which ideas are repressed but continue to operate unconsciously in the mind, and then reappear in consciousness under certain circumstances. Much of Freud's theory was based on his investigations of patients suffering from "hysteria" and neurosis. Hysteria was an ancient diagnosis that was primarily used for women with a wide variety of symptoms, including physical symptoms and emotional disturbances with no apparent physical cause. The history of the term can be traced to ancient Greece, where the idea emerged that a woman's uterus could float around her body and cause a variety of disturbances. Freud theorized instead that many of his patients’ problems arose from the unconscious mind. In Freud’s view, the unconscious mind was a repository of feelings and urges of which we have no awareness. The treatment of a patient referred to as Anna O. is regarded as marking the beginning of psychoanalysis. Freud worked together with Austrian physician Josef Breuer to treat Anna O.'s "hysteria," which Freud implied was a result of the resentment she felt over her father's real and physical illness that later led to his death. Today many researchers believe that her illness was not psychological, as Freud suggested, but either neurological or organic. Freud's structural model of personality divides the personality into three parts—the id, the ego, and the superego. The id is the unconscious part that is the cauldron of raw drives, such as for sex or aggression. The ego, which has conscious and unconscious elements, is the rational and reasonable part of personality. Its role is to maintain contact with the outside world to keep the individual in touch with society, and to do this it mediates between the conflicting tendencies of the id and the superego. The superego is a person's conscience, which develops early in life and is learned from parents, teachers, and others. Like the ego, the superego has conscious and unconscious elements. When all three parts of the personality are in dynamic equilibrium, the individual is thought to be mentally healthy. However, if the ego is unable to mediate between the id and the superego, an imbalance is believed to occur in the form of psychological distress.
John B. Watson was an American psychologist who is best known for his controversial "Little Albert" experiment. In this experiment, he used classical conditioning to teach a nine-month-old boy to be afraid of a white toy rat by associating the rat with a sudden loud noise. This study demonstrated how emotions could become conditioned responses.
Edward Lee Thorndike was an American psychologist whose work on animal behavior and the learning process led to the "law of effect." The law of effect states that responses that create a satisfying effect are more likely to occur again, while responses that produce a discomforting effect become less likely to occur. "Operant conditioning," a term coined by psychologist B. F. Skinner, describes a form of learning in which a voluntary response is strengthened or weakened depending on its association with either positive or negative consequences. The strengthening of a response occurs through reinforcement. Skinner described two types of reinforcement: positive reinforcement, which is the introduction of a positive consequence such as food, pleasurable activities, or attention from others, and negative reinforcement, which is the removal of a negative consequence such as pain or a loud noise. Skinner saw human behavior as shaped by trial and error through reinforcement and punishment, without any reference to inner conflicts or perceptions. In his theory, mental disorders represented maladaptive behaviors that were learned and could be unlearned through behavior modification. In the second half of the 20th century, behaviorism was expanded through advances in cognitive theories. While behaviorism and cognitive schools of psychological thought may not agree theoretically, they have complemented each other in practical therapeutic applications like cognitive-behavioral therapy (CBT), which has been used widely in the treatment of many different mental disorders, such as phobias, PTSD, and addiction. Some behavior therapies employ Skinner's theories of operant conditioning: by not reinforcing certain behaviors, these behaviors can be extinguished. Skinner's radical behaviorism advanced a "triple contingency" model, which explored the links between the environment, behavior, and the mind. This later gave rise to applied behavior analysis (ABA), in which operant conditioning techniques are used to reinforce positive behaviors and punish unwanted behaviors. This approach to treatment has been an effective tool to help children on the autism spectrum; however, it is considered controversial by many who see it as attempting to change or "normalize" autistic behaviors (Lovaas, 1987, 2003; Sallows & Graupner, 2005; Wolf & Risley, 1967). Cognitive psychology is the school of psychology that examines internal mental processes such as problem solving, memory, and language. "Cognition" refers to thinking and memory processes, and "cognitive development" refers to long-term changes in these processes. Much of the work derived from cognitive psychology has been integrated into various other modern disciplines of psychological study, including social psychology, personality psychology, abnormal psychology, developmental psychology, educational psychology, and behavioral economics.Cognitive psychology is radically different from previous psychological approaches in that it is characterized by both of the following:
Humanistic psychology is a psychological perspective that rose to prominence in the mid-20th century, drawing on the philosophies of existentialism and phenomenology, as well as Eastern philosophy. It adopts a holistic approach to human existence through investigations of concepts such as meaning, values, freedom, tragedy, personal responsibility, human potential, spirituality, and self-actualization. The humanistic perspective is a holistic psychological perspective that attributes human characteristics and actions to free will and an innate drive for self-actualization. This approach focuses on maximum human potential and achievement rather than psychoses and symptoms of disorder. It emphasizes that people are inherently good and pays special attention to personal experiences and creativity. This perspective has led to advances in positive, educational, and industrial psychology, and has been applauded for its successful application to psychotherapy and social issues. Despite its great influence, humanistic psychology has also been criticized for its subjectivity and lack of evidence. In the late 1950s, a group of psychologists convened in Detroit, Michigan, to discuss their interest in a psychology that focused on uniquely human issues, such as the self, self-actualization, health, hope, love, creativity, nature, being, becoming, individuality, and meaning. These preliminary meetings eventually culminated in the description of humanistic psychology as a recognizable "third force" in psychology, along with behaviorism and psychoanalysis. Humanism's major theorists were Abraham Maslow, Carl Rogers, Rollo May, and Clark Moustakas; it was also influenced by psychoanalytic theorists, including Wilhelm Reich, who discussed an essentially good, healthy core self, and Carl Gustav Jung, who emphasized the concept of archetypes. Abraham Maslow (1908–1970) is considered the founder of humanistic psychology, and is noted for his conceptualization of a hierarchy of human needs. He believed that every person has a strong desire to realize his or her full potential—or to reach what he called "self-actualization." Unlike many of his predecessors, Maslow studied mentally healthy individuals instead of people with serious psychological issues. Through his research he coined the term "peak experiences," which he defined as "high points" in which people feel at harmony with themselves and their surroundings. Self-actualized people, he believed, have more of these peak experiences throughout a given day than others. To explain his theories, Maslow created a visual, which he termed the "hierarchy of needs." This pyramid depicts various levels of physical and psychological needs that a person progresses through during their lifetime. At the bottom of the pyramid are the basic physiological needs of a human being, such as food and water. The next level is safety, which includes shelter and needs paramount to physical survival. The third level, love and belonging, is the psychological need to share oneself with others. The fourth level, esteem, focuses on success, status, and accomplishments. The top of the pyramid is self-actualization, in which a person is believed to have reached a state of harmony and understanding. Individuals progress from lower to higher stages throughout their lives, and cannot reach higher stages without first meeting the lower needs that come before them.
Carl Rogers (1902–1987) is best known for his person-centered approach, in which the relationship between therapist and client is used to help the patient reach a state of realization, so that they can then help themselves. His non-directive approach focuses more on the present than the past and centers on clients' capacity for self-direction and understanding of their own development. The therapist encourages the patient to express their feelings and does not suggest how the person might wish to change. Instead, the therapist uses the skills of active listening and mirroring to help patients explore and understand their feelings for themselves.
Rogers is also known for practicing "unconditional positive regard," which is defined as accepting a person in their entirety with no negative judgment of their essential worth. He believed that those raised in an environment of unconditional positive regard have the opportunity to fully actualize themselves, while those raised in an environment of conditional positive regard only feel worthy if they match conditions that have been laid down by others. Rollo May (1909–1994) was the best known American existential psychologist, and differed from other humanistic psychologists by showing a sharper awareness of the tragic dimensions of human existence. May was influenced by American humanism, and emphasized the importance of human choice. Humanistic psychology is holistic in nature: it takes whole persons into account rather than their separate traits or processes. In this way, people are not reduced to one particular attribute or set of characteristics, but instead are appreciated for the complex beings that they are. Humanistic psychology allows for a personality concept that is dynamic and fluid and accounts for much of the change a person experiences over a lifetime. It stresses the importance of free will and personal responsibility for decision-making; this view gives the conscious human being some necessary autonomy and frees them from deterministic principles. Perhaps most importantly, the humanistic perspective emphasizes the need to strive for positive goals and explains human potential in a way that other theories cannot. However, critics have taken issue with many of the early tenets of humanism, such as its lack of empirical evidence (as was the case with most early psychological approaches). Because of the inherent subjective nature of the humanistic approach, psychologists worry that this perspective does not identify enough constant variables in order to be researched with consistency and accuracy. Psychologists also worry that such an extreme focus on the subjective experience of the individual does little to explain or appreciate the impact of external societal factors on personality development. In addition, The major tenet of humanistic personality psychology—namely, that people are innately good and intuitively seek positive goals—does not account for the presence of deviance in the world within normal, functioning personalities. Sociocultural factors are the larger-scale forces within cultures and societies that affect the thoughts, feelings, and behaviors of individuals. These include forces such as attitudes, child-rearing practices, discrimination and prejudice, ethnic and racial identity, gender roles and norms, family and kinship structures, power dynamics, regional differences, religious beliefs and practices, rituals, and taboos. Several subfields within psychology seek to examine these sociocultural factors that influence human mental states and behavior; among these are social psychology, cultural psychology, and cultural-historical psychology. Cultural psychology is the study of how psychological and behavioral tendencies are rooted and embedded within culture. The main tenet of cultural psychology is that mind and culture are inseparable and mutually constitutive, meaning that people are shaped by their culture and their culture is also shaped by them. A major goal of cultural psychology is to expand the number and variation of cultures that contribute to basic psychological theories, so that these theories become more relevant to the predictions, descriptions, and explanations of all human behaviors—not just Western ones. Populations that are Western, educated, and industrialized tend to be overrepresented in psychological research, yet findings from this research tend to be labeled "universal" and inaccurately applied to other cultures. The evidence that social values, logical reasoning, and basic cognitive and motivational processes vary across populations has become increasingly difficult to ignore. By studying only a narrow range of culture within human populations, psychologists fail to account for a substantial amount of diversity.
Behavioral neuroscience has a strong history of contributing to the understanding of medical disorders, including those that fall into the realm of clinical psychology. Neuropsychologists are often employed as scientists to advance scientific or medical knowledge, and neuropsychology is particularly concerned with understanding brain injuries in an attempt to learn about normal psychological functioning. Neuroimaging tools, such as functional magnetic resonance imaging (fMRI) scans, are often used to observe which areas of the brain are active during particular tasks in order to help psychologists understand the link between brain and behavior.
Biopsychology as a scientific discipline emerged from a variety of scientific and philosophical traditions in the 18th and 19th centuries. Philosophers like Rene Descartes proposed physical models to explain animal and human behavior. Descartes suggested, for example, that the pineal gland, a midline unpaired structure in the brain of many organisms, was the point of contact between mind and body. In The Principles of Psychology (1890), William James argued that the scientific study of psychology should be grounded in an understanding of biology. The emergence of both psychology and behavioral neuroscience as legitimate sciences can be traced to the emergence of physiology during the 18th and 19th centuries; however, it was not until 1914 that the term "psychobiology" was first used in its modern sense by Knight Dunlap in An Outline of Psychobiology.
