A theoretical orientation or perspective in psychology presents a framework through which to understand, organize, and predict human behaviour.
Because human behaviour is immensely complex, no single theory can fully account for it.
Instead, different psychological perspectives make varied assumptions about what aspects of a person should be the focus of study, which in turn determines their preferred methods of investigation, their view of psychological development, and their approaches to treatment
Today, the field is defined by several major perspectives, each acting as a different lens that highlights unique factors of the human mind and behavior.
1. Psychodynamic Perspective
Originating with the Austrian physician Sigmund Freud in the early 20th century, the psychoanalytic or psychodynamic perspective was the first comprehensive theory of personality.
The psychodynamic approach argues that human behaviour is primarily motivated by inner forces, repressed memories, and unconscious conflicts over which individuals have little awareness or control.
The Structure of the Mind
Freud compared the mind to an iceberg, with only a small amount of it being visible, that is our observable behavior.
However, 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.
Freud proposed that the personality is composed of three structures: the id (driven by primitive, instinctual urges like sex and aggression), the ego (which attempts to balance the id with reality), and the superego (the moral conscience of society).
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.
Psychosexual Development
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.
Evaluation of the Psychodynamic Approach
However, it has been criticized in the way that it over emphasizes the importance of sexuality and under emphasized 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.
Over time, this perspective evolved beyond Freud’s strict biological drives into schools such as ego psychology, object relations theory, and attachment theory, which place a greater emphasis on the interpersonal matrix of infancy, the development of the self, and adaptation to the social environment.
2. Behaviorist Perspective
Emerging as a radical reaction against early psychology’s focus on subjective introspection and unobservable mental states, behaviorism argues that psychology should be a purely objective natural science.
Championed by figures like John B. Watson, behaviourists proposed that all behaviour is learned and shaped by the external environment, effectively dismissing the study of the unconsciousness as flawed and unscientific.
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.
The behaviorist perspective is concerned with how environmental factors (called stimuli) affect observable behavior (called the response).
The behaviorist perspective proposes two main processes whereby people learn from their environment: namely classical conditioning and operant conditioning.
Classical 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.
Operant Conditioning
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.
Key Assumptions of Behaviorism
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.
Evaluation of the Behaviorist Approach
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.
3. Humanistic Perspective
In the mid-20th century, humanism emerged as the “third force” in psychology, reacting against the pessimistic determinism of psychoanalysis and the mechanistic, reductionist nature of behaviourism.
Humanistic psychology is a psychological perspective that emphasizes the study of the whole person (know as holism).
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.
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 life.
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.
4. Cognitive Perspective
The 1950s brought about the cognitive revolution, which redirected psychology’s attention back to the mind and internal mental processes.
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.
Cognitive psychology focuses on how people input, process, store, and retrieve information, covering complex functions like perception, attention, memory, reasoning, language, and problem-solving.
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.
Theorists such as Jean Piaget introduced the concept of schemas, mental frameworks built from past experiences that individuals use to organize knowledge, interpret new situations, and make mental shortcuts
A central feature of this approach is the computer metaphor, which conceptualizes the human mind as an information-processing system similar to a digital computer’s software and hardware.
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).
5. Biological & Neuroscience Perspectives
The biological perspective assumes that all human behaviour, emotions, and thoughts have a physical origin within the body.
This approach focuses on the anatomy and physiology of the central nervous system, particularly the brain, as well as the endocrine (hormonal) system.
Biological psychologists investigate how brain structure, neurochemistry (e.g., neurotransmitter imbalances like serotonin or dopamine), and genetics dictate behaviour and vulnerability to psychological disorders.
The biological perspective is highly scientific, frequently utilizing advanced brain-imaging technologies like fMRI and PET scans to pinpoint the localization of brain functions.
It aligns closely with the biomedical model of health, which typically treats psychological abnormalities through pharmacological interventions or other medical procedures designed to alter brain chemistry.
6. Evolutionary Psychology
Rooted in Charles Darwin’s theory of natural selection, evolutionary psychology extends biological principles to explain how modern human behaviours have evolved.
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 to survive and reproduce.
The core assumption is that cognitive processes and behavioural tendencies, such as face recognition, language acquisition, mate selection, and even altruism, exist today because they provided an adaptive survival or reproductive advantage to our hunter-gatherer ancestors
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.
7. Sociocultural Perspective
The sociocultural (or social constructionist) perspective looks outward, emphasizing that an individual’s thoughts, feelings, and behaviours are profoundly shaped by the society and culture in which they live.
This view argues that psychological phenomena cannot be understood in isolation from their social context, interpersonal interactions, or historical period.
It examines how societal norms, poverty, prejudice, and group dynamics influence cognitive processing and behaviour, highlighting that what is considered “normal” or “abnormal” is often dictated by cultural and historical contexts
Integrative Perspectives
Because human behaviour and the mind are immensely complex, no single “grand” theory or perspective can fully explain them.
While early psychology was defined by competing schools of thought, modern psychology largely views these different theoretical approaches as complementary rather than mutually exclusive.
This realization has led to the rise of integrative approaches, which blend concepts, methodologies, and interventions from multiple psychological disciplines to create a more comprehensive, holistic understanding of the human experience.
Example
Perhaps the most prominent integrative framework in contemporary psychology and health is the biopsychosocial model.
This model emerged as a direct challenge to the traditional, reductionist biomedical model, which argued that illnesses and psychological disorders were solely the result of biological pathologies (such as viruses, genetic defects, or chemical imbalances) and ignored subjective experience).
Instead, the biopsychosocial model asserts that health, illness, and human behaviour are the dynamic products of three interacting factors:
- Biological factors: Genetics, neurochemistry, viruses, brain structure, and physical lesions.
- Psychological factors: Cognitions, emotions, expectations, coping skills, stress, and behaviors (such as diet or smoking).
- Social and Cultural factors: Socioeconomic status, family circumstances, social norms, prejudice, cultural values, and employment.
By treating the person holistically, this approach recognizes that “micro-level” processes (like brain chemistry) and “macro-level” processes (like social support networks) continuously influence one another.
Today, it is heavily utilized in treating complex issues like chronic pain, obesity, and addiction, where a combination of medical, cognitive, and social interventions proves far more effective than targeting biology alone.
