There are various approaches in contemporary psychology.
An approach is a perspective (i.e., view) that involves certain assumptions (i.e., beliefs) about human behavior: the way they function, which aspects of them are worthy of study and what research methods are appropriate for undertaking this study. There may be several different theories within an approach, but they all share these common assumptions.
You may wonder why there are so many different psychology perspectives and whether one approach is correct and others wrong. Most psychologists would agree that no one perspective is correct, although in the past, in the early days of psychology, the behaviorist would have said their perspective was the only truly scientific one.
Each perspective has its strengths and weaknesses, and brings something different to our understanding of human behavior. For this reason, it is important that psychology does have different perspectives on the understanding and study of human and animal behavior.
Below is a summary of the six main psychological approaches (sometimes called perspectives) in psychology.
If your layperson's idea of psychology has always been about people in laboratories wearing white coats and watching hapless rats try to negotiate mazes in order to get to their dinner, then you are probably thinking about behavioral psychology.
Behaviorism is different from most other approaches because they view people (and animals) as controlled by their environment and specifically that we are the result of what we have learned from our environment. Behaviorism is concerned with how environmental factors (called stimuli) affect observable behavior (called the response).
The behaviorist approach proposes two main processes whereby people learn from their environment: namely classical conditioning and operant conditioning. Classical conditioning involves learning by association, and operant conditioning involves learning from the consequences of behavior.
Classical conditioning (CC) was studied by the Russian psychologist Ivan Pavlov. Though looking into natural reflexes and neutral stimuli he managed to condition dogs to salivate to the sound of a bell through repeated associated with the sound of the bell and food. The principles of CC have been applied in many therapies. These include systematic desensitization for phobias (step-by-step exposed to a feared stimulus at once) and aversion therapy.
B.F. Skinner investigated operant conditioning of voluntary and involuntary behavior. Skinner felt that some behavior could be explained by the person's motive. Therefore behavior occurs for a reason, and the three main behavior shaping techniques are positive reinforcement, negative reinforcement, and punishment.
Behaviorism also believes in scientific methodology (e.g., controlled experiments), and that only observable behavior should be studied because this can be objectively measured. Behaviorism rejects the idea that people have free will, and believes that the environment determines all behavior. Behaviorism is the scientific study of observable behavior working on the basis that behavior can be reduced to learned S-R (Stimulus-Response) units.
Behaviorism has been criticized in the way it under-estimates the complexity of human behavior. Many studies used animals which are hard to generalize to humans, and it cannot explain, for example, the speed in which we pick up language. There must be biological factors involved.
Who hasn't heard of Sigmund Freud? So many expressions of our daily life come from Freud's theories of psychoanalysis - subconscious, denial, repression and anal personality to name only a few.
Freud believes that events in our childhood can have a significant impact on our behavior as adults. He also believed that people have little free will to make choices in life. Instead, our behavior is determined by the unconscious mind and childhood experiences.
Freud’s psychoanalysis is both a theory and therapy. It is the original psychodynamic theory and inspired psychologists such as Jung and Erikson to develop their own psychodynamic theories. Freud’s work is vast, and he has contributed greatly to psychology as a discipline.
Freud, the founder of psychoanalysis, explained the human mind as like an iceberg, with only a small amount of it being visible, that is our observable behavior, but it is the unconscious, submerged mind that has the most, underlying influence on our behavior. Freud used three main methods of accessing the unconscious mind: free association, dream analysis and slips of the tongue.
He believed that the unconscious mind consisted of three components: the 'id' the 'ego' and the 'superego.' The 'id' contains two main instincts: 'Eros', which is the life instinct, which involves self-preservation and sex which is fuelled by the 'libido' energy force. 'Thanatos' is the death instinct, whose energies, because they are less powerful than those of 'Eros' are channeled away from ourselves and into aggression towards others.
The 'id' and the 'superego' are constantly in conflict with each other, and the 'ego' tries to resolve the discord. If this conflict is not resolved, we tend to use defense mechanisms to reduce our anxiety. Psychoanalysis attempts to help patients resolve their inner conflicts.
An aspect of psychoanalysis is Freud's theory of psychosexual development. It shows how early experiences affect adult personality. Stimulation of different areas of the body is important as the child progresses through the important developmental stages. Too much or too little can have bad consequences later.
The most important stage is the phallic stage where the focus of the libido is on the genitals. During this stage little boys experience the 'Oedipus complex,' and little girls experience the 'Electra complex.' These complexes result in children identifying with their same-sex parent, which enables them to learn sex-appropriate behavior and a moral code of conduct.
However, it has been criticized in the way that it over emphasizes the importance of sexuality and under emphasized of the role of social relationships. The theory is not scientific, and can't be proved as it is circular. Nevertheless, psychoanalysis has been greatly contributory to psychology in that it has encouraged many modern theorists to modify it for the better, using its basic principles, but eliminating its major flaws.
Humanistic psychology is a psychological perspective that emphasizes the study of the whole person (know as holism). Humanistic psychologists look at human behavior, not only through the eyes of the observer, but through the eyes of the person doing the behaving.
Humanistic psychologists believe that an individual's behavior is connected to his inner feelings and self-image. The humanistic perspective centers on the view that each person is unique and individual, and has the free will to change at any time in his or her lives.
The humanistic perspective suggests that we are each responsible for our own happiness and well-being as humans. We have the innate (i.e., inborn) capacity for self-actualization, which is our unique desire to achieve our highest potential as people.
Because of this focus on the person and his or her personal experiences and subjective perception of the world the humanists regarded scientific methods as inappropriate for studying behavior.
Two of the most influential and enduring theories in humanistic psychology that emerged in the 1950s and 1960s are those of Carl Rogers and Abraham Maslow.
Psychology was institutionalized as a science in 1879 by Wilhelm Wundt, who found the first psychological laboratory.
His initiative was soon followed by other European and American Universities. These early laboratories, through experiments, explored areas such as memory and sensory perception, both of which Wundt believed to be closely related to physiological processes in the brain. The whole movement had evolved from the early philosophers, such as Aristotle and Plato. Today this approach is known as cognitive psychology.
Cognitive Psychology revolves around the notion that if we want to know what makes people tick then the way to do it is to figure out what processes are actually going on in their minds. In other words, psychologists from this perspective study cognition which is ‘the mental act or process by which knowledge is acquired.’
The cognitive perspective is concerned with “mental” functions such as memory, perception, attention, etc. It views people as being similar to computers in the way we process information (e.g., input-process-output). For example, both human brains and computers process information, store data and have input an output procedure.
This had led cognitive psychologists to explain that memory comprises of three stages: encoding (where information is received and attended to), storage (where the information is retained) and retrieval (where the information is recalled).
It is an extremely scientific approach and typically uses lab experiments to study human behavior. The cognitive approach has many applications including cognitive therapy and eyewitness testimony.
We can thank Charles Darwin (1859) for demonstrating the idea that genetics and evolution play a role in influencing human behavior through natural selection.
Theorists in the biological perspective who study behavioral genomics consider how genes affect behavior. Now that the human genome is mapped, perhaps, we will someday understand more precisely how behavior is affected by the DNA we inherit. Biological factors such as chromosomes, hormones and the brain all have a significant influence on human behavior, for example, gender.
The biological approach believes that most behavior is inherited and has an adaptive (or evolutionary) function. For example, in the weeks immediately after the birth of a child, levels of testosterone in fathers drop by more than 30 per cent. This has an evolutionary function. Testosterone-deprived men are less likely to wander off in search of new mates to inseminate. They are also less aggressive, which is useful when there is a baby around.
Biological psychologists explain behaviors in neurological terms, i.e., the physiology and structure of the brain and how this influences behavior. Many biological psychologists have concentrated on abnormal behavior and have tried to explain it. For example, biological psychologists believe that schizophrenia is affected by levels of dopamine (a neurotransmitter).
These findings have helped psychiatry take off and help relieve the symptoms of the mental illness through drugs. However, Freud and other disciplines would argue that this just treats the symptoms and not the cause. This is where health psychologists take the finding that biological psychologists produce and look at the environmental factors that are involved to get a better picture.
A central claim of evolutionary psychology is that the brain (and therefore the mind) evolved to solve problems encountered by our hunter-gatherer ancestors during the upper Pleistocene period over 10,000 years ago.
The Evolutionary approach explains behavior in terms of the selective pressures that shape behavior. Most behaviors that we see/display are believed to have developed during our EEA (environment of evolutionary adaptation) to help us survive.
Observed behavior is likely to have developed because it is adaptive. It has been naturally selected, i.e., individuals who are best adapted survive and reproduce. Behaviors may even be sexually selected, i.e., individuals who are most successful in gaining access to mates leave behind more offspring.
The mind is therefore equipped with ‘instincts’ that enabled our ancestors to survive and reproduce.
A strength of this approach is that it can explain behaviors that appear dysfunctional, such as anorexia, or behaviors that make little sense in a modern context, such as our biological stress response when finding out we are overdrawn at the bank.
Therefore, in conclusion, there are so many different perspectives in psychology to explain the different types of behavior and give different angles. No one perspective has explanatory powers over the rest.
Only with all the different types of psychology, which sometimes contradict one another (nature-nurture debate), overlap with each other (e.g. psychoanalysis and child psychology) or build upon one another (biological and health psychologist) can we understand and create effective solutions when problems arise, so we have a healthy body and a healthy mind.
The fact that there are different perspectives represents the complexity and richness of human (and animal) behavior. A scientific approach, such as behaviorism or cognitive psychology, tends to ignore the subjective (i.e., personal) experiences that people have.
The humanistic perspective does recognize human experience, but largely at the expense of being non-scientific in its methods and ability to provide evidence. The psychodynamic perspective concentrates too much on the unconscious mind and childhood. As such, it tends to lose sight of the role of socialization (which is different in each country) and the possibility of free will.
The biological perspective reduces humans to a set of mechanisms and physical structures that are clearly essential and important (e.g., genes). However, it fails to account for consciousness and the influence of the environment on behavior.

5 Major Perspectives in Psychology
Why do you act the way you do? Have you ever wondered why some people are the life of the party and others prefer to curl up with a good book? Or why you remember certain events but not others? People have studied the mind and how it works since the time of the ancient Greeks, but the scientific study of psychology only dates back to a little over a hundred years ago.
Since Wilhelm Wundt opened the first psychology lab in 1879, psychologists have studied various aspects of human behavior, such as personality, brain functions and socio-cultural influences. As psychology progressed, it began to tackle the question of why we do what we do from different angles, including: biological, psychodynamic, behavioral, cognitive and humanistic perspectives. Let's look at each of these five main approaches that guide modern psychological research.
Biopsychologists look at how your nervous system, hormones and genetic makeup affect your behavior. Biological psychologists explore the connection between your mental states and your brain, nerves and hormones to explore how your thoughts, moods and actions are shaped.
So what does that mean? It means that for the biological approach, you are the sum of your parts. You think the way you do because of the way your brain is built and because of your body's needs. All of your choices are based on your physical body. The biological approach attempts to understand the healthy brain, but it also examines the mind and body to figure out how disorders like schizophrenia develop from genetic roots.
The psychodynamic approach was promoted by Sigmund Freud, who believed that many of our impulses are driven by sex. Psychologists in this school of thought believe that unconscious drives and experiences from early childhood are at the root of your behaviors and that conflict arises when societal restrictions are placed on these urges.
There are a lot of jokes about Freud and his now mostly outdated theories. But have you ever thought that something about who you are today comes from your experiences as a child? Say, you blame your smoking habit on an oral fixation that stems from being weaned from breastfeeding too early as a baby. Well, that also comes from Freud's theories, and it was an idea that revolutionized how we see ourselves.
Behavioral psychologists believe that external environmental stimuli influence your behavior and that you can be trained to act a certain way. Behaviorists like B.F. Skinner don't believe in free will. They believe that you learn through a system of reinforcements and punishment.
The behavioral approach is really effective when you don't care what someone thinks, as long as you get the desired behavior. The influence of these theories affects us every day and throughout our lives, impacting everything from why we follow the rules of the road when driving to how advertising companies build campaigns to get us to buy their products.
In contrast to behaviorists, cognitive psychologists believe that your behavior is determined by your expectations and emotions. Cognitive psychologist Jean Piaget would argue that you remember things based on what you already know. You also solve problems based on your memory of past experiences.
So, with this approach, we turn away from people as machines without free will and delve back into thoughts and feelings. How you act is based upon internal processes, and there is much more stress upon individuals. From a cognitive perspective, your expectations of an upcoming party will affect how you feel and act while you're there and will color your memory of the night after you return home.
Humanistic psychologists believe that you're essentially good and that you're motivated to realize your full potential. Psychologists from this camp focus on how you can feel good about yourself by fulfilling your needs and goals. The prominent humanistic psychologist Carl Rogers called his patients 'clients' and offered a supportive environment in which clients could gain insight into their own feelings.
In contrast to the behavioral approach, the humanistic approach works on individual empowerment. Whether you are right or not, in a larger sense, you are motivated to be the best person you can be. All your choices come from trying to improve your life. So, if you're trying to cut back on your nightly wine consumption, a humanistic therapist would be encouraging and supportive but won't directly advise you to quit or try to analyze why you drink in the first place.
- Psychology is the scientificstudy of human thought, feelingsand behavior.
- The five major perspectives in psychology arebiological, psychodynamic, behavioral, cognitiveandhumanistic.
- Each perspective provides its own view on the roots of why you do what you do.
