This study guide summarises the major models of abnormality commonly examined in UNISA PYC3702: Abnormal Behaviour and Mental Health. It explains how each model defines abnormal behaviour, what causes it, how it is assessed, and what treatment approaches tend to follow from it. The notes also compare the models, highlight their strengths and limitations, and show how they are applied in South African and broader university psychology contexts.
1. Understanding Abnormality in Psychology
Abnormality is one of the central topics in abnormal psychology because it determines what counts as a psychological disorder, how it is diagnosed, and what intervention is considered appropriate. In PYC3702, the concept is usually approached with caution, because no single definition fully captures the complexity of human behaviour. A behaviour may look unusual without being disordered, while a person may suffer intensely without displaying obviously strange behaviour. For this reason, abnormality is best understood as a multi-dimensional concept rather than a simple label.
1.1 Why the concept is difficult to define
A basic difficulty is that “abnormal” depends on the standard used. Behaviour that is normal in one culture, age group, or historical period may be considered abnormal in another. A person speaking to ancestors in a spiritual context, for example, might be viewed as religious in one community and as hallucinating in another. Similarly, intense grief after a death is usually expected, but if it becomes prolonged and severely disabling, it may suggest a disorder. This means that abnormality cannot be identified using one fixed rule alone.
Psychologists often use several criteria together:
- Deviance from social norms: behaviour differs from what a society expects.
- Statistical infrequency: behaviour is rare in the population.
- Distress: the person experiences emotional suffering.
- Dysfunction: the behaviour interferes with daily life.
- Danger: the person may harm self or others.
Each criterion contributes useful information, but each also has limitations. For example, statistical rarity does not automatically mean pathology. High intelligence is rare, but it is not abnormal in a clinical sense. In the same way, some forms of deviance are healthy or admirable, such as standing up against injustice. Therefore, abnormality is judged not only by how unusual something is, but also by whether it causes suffering, impairment, or risk.
1.2 The role of culture and context
Culture shapes what people believe, feel, and do. Because of this, abnormality must always be understood in context. A South African student experiencing visions during mourning might be understood differently depending on family tradition, religion, and community beliefs. A clinician who ignores cultural meaning may misdiagnose spiritual experiences as psychosis. This is why modern abnormal psychology emphasizes cultural competence and humility.
The South African context is especially important because the country is culturally diverse, multilingual, and historically shaped by inequality, trauma, violence, and social disruption. Stressors such as poverty, unemployment, crime, substance use, and family disruption can influence psychological distress and access to care. Thus, abnormal behaviour cannot be separated from the social world in which it appears. In many cases, symptoms reflect not only individual vulnerability but also environmental adversity.
1.3 The meaning of mental disorder
A mental disorder is usually understood as a pattern of thoughts, feelings, or behaviours that is clinically significant and associated with distress, dysfunction, or both. Importantly, a diagnosis does not imply that the person is weak or morally flawed. It indicates that a pattern of functioning has become maladaptive or harmful enough to warrant psychological or medical attention.
Many study guides and exam questions in PYC3702 expect students to distinguish between:
- Unusual behaviour
- Problem behaviour
- Clinical disorder
These are not identical. Unusual behaviour may simply reflect personality or culture. Problem behaviour may be harmful in one setting but not another. A clinical disorder is generally more persistent, more impairing, and more broadly significant. This distinction is essential in exam answers because it shows that the student understands abnormality as a carefully evaluated concept rather than a casual label.
1.4 The historical shift in thinking
Historically, abnormal behaviour was often explained through supernatural or moral ideas. People were thought to be possessed by spirits, punished by gods, or afflicted by witchcraft. Later, biological and medical explanations became dominant, especially with the rise of psychiatry. Psychological approaches then broadened the field again by showing that learning, cognition, family dynamics, and social environment also matter.
Modern abnormal psychology therefore does not rely on one explanation only. Instead, it uses a biopsychosocial perspective, which integrates biological, psychological, and social factors. This integrative view is especially useful in an exam because it captures the complexity of abnormal behaviour without reducing it to a single cause.
1.5 Exam relevance
When writing about abnormality in PYC3702, it is useful to remember three core ideas:
- Abnormality is relative to context.
- Abnormality is usually judged by more than one criterion.
- The concept should be approached with care, sensitivity, and cultural awareness.
A strong answer will not define abnormality in a rigid way. Instead, it will explain why the concept is contested, how psychologists try to operationalise it, and why the final judgement depends on both symptoms and context.
2. The Supernatural, Biological, and Psychodynamic Models
The major models of abnormality each offer a different explanation for why psychological disorders occur. Some models emphasise external forces, others internal processes, and others bodily mechanisms. In exam questions, it is often useful to compare these models directly because they represent different theoretical traditions in psychology and psychiatry.
2.1 The supernatural model
The supernatural model explains abnormal behaviour as caused by forces beyond the ordinary natural world. These may include:
- Demons or evil spirits
- Witchcraft or curses
- An angry deity
- Possession
- Astrological influence
This model is among the oldest in human history and still appears in many cultural and religious settings. It can be meaningful to people because it offers a coherent explanation for otherwise frightening behaviour. It may also reduce shame if the person believes they are spiritually afflicted rather than personally defective. However, it can be dangerous if it leads to harmful practices, delayed treatment, or stigma.
From a psychological perspective, the supernatural model has limited scientific support because its claims are generally not testable in empirical terms. Yet it remains important in abnormal psychology because cultural beliefs shape how symptoms are interpreted. A clinician who ignores supernatural explanations may fail to build trust with the patient and family. Therefore, while the model is not scientific in the strict sense, its social influence is real and must be understood.
Historically, some responses to supernatural explanations involved exorcism, prayer, or ritual cleansing. In modern settings, these practices may coexist with medical treatment when they are culturally acceptable and do not replace evidence-based care in situations of serious risk.
2.2 The biological model
The biological model views abnormal behaviour as the result of physical processes in the body, especially the brain and nervous system. It assumes that mental disorders are influenced by:
- Genetics and heredity
- Neurotransmitter imbalance
- Brain structure and function
- Hormonal irregularities
- Infection, injury, or neurological damage
- Evolutionary vulnerability
This model has been highly influential in modern psychiatry. It provides a strong basis for pharmacological treatment and for the use of brain imaging, genetic studies, and medical assessment. The biological model is especially useful for disorders with clear physiological links, such as certain forms of schizophrenia, bipolar disorder, some anxiety disorders, and substance-related disorders.
One strength of the biological model is that it can produce measurable hypotheses. For example, researchers can study whether a disorder is associated with reduced serotonin functioning, altered dopamine activity, or abnormal amygdala response. This makes the model scientifically attractive. Another strength is that it can reduce blame. If a disorder is understood as partly biological, the patient may feel less responsible for their suffering.
However, the biological model has limitations. It can become reductionistic if it treats complex human suffering as nothing more than chemistry. It may underplay trauma, relationships, poverty, and learned coping patterns. It also does not always explain why symptoms vary widely between individuals with similar biological vulnerabilities. Two people may have similar genetic risk, but only one develops a disorder because of life stress, support systems, or coping style. In such cases, biology is important but not sufficient.
2.2.1 The diathesis-stress idea
A useful extension of the biological model is the diathesis-stress model. Diathesis refers to a predisposition or vulnerability, while stress refers to environmental pressure that triggers symptoms. This model suggests that a person may inherit a vulnerability to depression, schizophrenia, or anxiety, but the disorder only emerges when stress exceeds a certain threshold. The model is valuable because it links biology to life experience rather than opposing them.
For example, a student with a family history of panic disorder may function well until facing a major academic failure, relationship loss, or chronic sleep deprivation. The vulnerability was present, but stress activated it. This helps explain why mental disorders often appear after significant life events.
2.3 The psychodynamic model
The psychodynamic model, associated with Sigmund Freud, explains abnormal behaviour in terms of unconscious conflicts, early childhood experiences, and defence mechanisms. According to this view, symptoms arise when unacceptable wishes, fears, or impulses are repressed rather than consciously resolved. Anxiety is managed through defences such as repression, denial, projection, displacement, rationalisation, and regression.
The psychodynamic model made an important historical contribution by highlighting that inner life matters and that symptoms may carry symbolic meaning. It also encouraged clinicians to look beneath the surface and consider developmental history. In this model, a symptom is not random; it may represent an indirect expression of conflict.
For example, a person with an intense fear of authority figures may have unresolved early experiences with a harsh parent. A person who repeatedly sabotages relationships may unconsciously fear intimacy because closeness was associated with rejection in childhood. Such interpretations can be clinically insightful, especially when the person’s present difficulties appear repetitive and emotionally charged.
2.3.1 Strengths of the psychodynamic model
The model remains influential because it:
- Emphasises the importance of childhood
- Recognises unconscious processes
- Explains why symptoms may have symbolic meaning
- Values the therapeutic relationship
- Helps clinicians explore patterns rather than isolated symptoms
It also paved the way for many later therapeutic approaches, even when those approaches no longer use classical Freudian language.
2.3.2 Limitations of the psychodynamic model
The model is criticised because many of its concepts are difficult to test scientifically. Some explanations can become vague or overly interpretive. Also, the assumption that childhood conflict is the main source of disorders can be too narrow. Not all psychological disorders can be traced convincingly to early psychosexual stages or family dynamics. Moreover, psychodynamic treatment may be lengthy and less accessible than shorter evidence-based interventions.
2.4 Comparing the three models
A useful exam strategy is to compare the supernatural, biological, and psychodynamic models in one coherent framework. Their key differences can be summarised as follows:
| Model | Main cause of abnormality | Typical view of the person | Common intervention |
|---|---|---|---|
| Supernatural | Spirits, curses, divine forces | Afflicted or possessed | Ritual, prayer, exorcism |
| Biological | Genes, brain, hormones, physiology | Biologically vulnerable organism | Medication, medical treatment |
| Psychodynamic | Unconscious conflict, childhood experiences | Person with hidden inner conflict | Insight-oriented therapy |
These models differ not only in explanation but also in assumptions about human nature. The supernatural model sees meaning outside the individual. The biological model sees the body as central. The psychodynamic model sees inner conflict as central. In practice, real-world treatment often combines several perspectives.
3. The Behavioural, Cognitive, and Cognitive-Behavioural Models
Where the earlier models focus on spiritual forces, biology, or inner conflict, the behavioural and cognitive traditions focus on learning, thinking, and observable patterns. These models are particularly important in modern clinical psychology because they connect symptoms to mechanisms that can be assessed and changed.
3.1 The behavioural model
The behavioural model argues that abnormal behaviour is learned in the same way as normal behaviour. It does not assume that symptoms come from hidden forces or unconscious conflicts. Instead, it focuses on how behaviour is acquired and maintained through environmental contingencies.
The main learning principles are:
- Classical conditioning
- Operant conditioning
- Observational learning
- Avoidance learning
Classical conditioning occurs when a neutral stimulus becomes associated with a fear or emotional response. A person bitten by a dog may later fear all dogs after associating them with pain. Operant conditioning occurs when behaviours are strengthened by reinforcement. Avoidance behaviour, such as repeatedly avoiding social situations, may be reinforced because it reduces immediate anxiety. Observational learning occurs when people learn by watching others. A child who sees a parent panic in elevators may develop a similar fear.
Behavioural explanations are useful because they show how symptoms can persist even when they no longer make sense. Avoidance reduces anxiety in the short term, which reinforces it, but it also prevents the person from learning that the feared situation is safe. This is one reason phobias can become chronic.
3.1.1 Behavioural strengths
The behavioural model has several strong points:
- It is based on observable processes
- It offers clear treatment implications
- It is supported by research in learning theory
- It helps explain habits, fears, compulsions, and avoidant behaviour
Behavioural methods also led to practical interventions such as exposure therapy, systematic desensitisation, token economies, and behavioural activation. These treatments are often effective because they target the maintaining factors of the disorder rather than only its symptoms.
3.1.2 Behavioural limitations
The model is less able to explain why different people respond differently to the same learning experiences. Not everyone develops a phobia after a frightening event. Some individuals appear more biologically or cognitively vulnerable than others. The model can also understate the role of thoughts, meanings, emotions, and internal interpretation. Human behaviour is not just reflexive learning; it is shaped by beliefs and expectations as well.
3.2 The cognitive model
The cognitive model explains abnormal behaviour in terms of faulty thinking, distorted beliefs, biased attention, and maladaptive interpretations. According to this view, psychological distress is influenced by how people interpret events rather than by events alone. The same situation may produce different emotional outcomes depending on the person’s thoughts.
For example, if a student fails an exam, one student may think, “I did badly, but I can improve,” while another may think, “I am a failure and everything is ruined.” The second interpretation is more likely to produce hopelessness, anxiety, and depression. Cognitive theory therefore emphasises the role of automatic thoughts, schemas, core beliefs, and attributional style.
Common cognitive distortions include:
- Catastrophising
- Overgeneralisation
- All-or-nothing thinking
- Mind reading
- Personalisation
- Selective attention to negative evidence
- Black-and-white evaluation
These distortions are common in many disorders, especially depression and anxiety. They can also influence body image problems, obsessive concerns, and social fears.
3.2.1 Cognitive strengths
The cognitive model is valuable because it explains how the same event can lead to different outcomes depending on interpretation. It is also highly useful in therapy, especially cognitive restructuring and problem-solving approaches. The model has strong empirical support, particularly in research on depression, anxiety, and stress.
3.2.2 Cognitive limitations
The model can sometimes overemphasise conscious thought and underplay emotion, biology, and context. Not all symptoms begin with distorted thinking; some arise from trauma, neurochemical changes, or chronic stress. Also, some beliefs are consequences rather than causes of disorder. A depressed person may think negatively because they are already depressed. This makes causal direction difficult to establish.
3.3 The cognitive-behavioural model
The cognitive-behavioural model combines the learning principles of behaviourism with the thought-focused insights of cognitive theory. It argues that thoughts, emotions, and behaviour influence one another in a continuous cycle. A person’s beliefs shape their actions, their actions shape their feelings, and their feelings reinforce their beliefs.
This integrated view is especially useful because it avoids the limitations of a purely behavioural or purely cognitive account. A person with social anxiety may have learned to fear criticism through conditioning, but the disorder is maintained by distorted beliefs such as “Everyone will judge me” and by avoidance behaviours that prevent corrective learning.
The cognitive-behavioural model has become one of the most influential frameworks in contemporary clinical psychology because it supports structured, time-limited, and evidence-based interventions. It is also easier to manualise, which makes it suitable for training and research.
3.4 Why these models matter in clinical practice
Behavioural and cognitive models are important because they translate directly into intervention. If a disorder is maintained by avoidance, exposure can help. If it is maintained by distorted beliefs, cognitive restructuring can help. If it involves low reinforcement and reduced activity, behavioural activation can help. This practical orientation makes these models especially significant in university study contexts where students must link theory to treatment.
A useful comparison is shown below:
| Model | Main focus | Key mechanism | Typical treatment implication |
|---|---|---|---|
| Behavioural | Learning history and reinforcement | Conditioning, avoidance, imitation | Exposure, reinforcement, behavioural rehearsal |
| Cognitive | Thoughts and appraisals | Distorted beliefs, schemas | Cognitive restructuring, thought monitoring |
| Cognitive-behavioural | Interaction of thoughts and behaviour | Vicious cycles | Combined CBT strategies |
In exam answers, it is useful to show that symptoms are not merely “in the head” or “in the environment” but arise from an ongoing interaction between learned patterns and interpretation.
4. Humanistic-Existential, Sociocultural, and Biopsychosocial Models
Not all models of abnormality are symptom-centred. Some focus on meaning, values, relationships, and social conditions. These perspectives are especially important because many forms of distress cannot be understood properly if the individual is isolated from their environment and life purpose.
4.1 The humanistic model
The humanistic model sees people as naturally oriented toward growth, authenticity, and self-actualisation. Abnormality arises when this growth is blocked, especially when a person’s experience of self is distorted by conditions of worth, alienation, or lack of acceptance. The model is associated with Carl Rogers and other humanistic theorists who stressed empathy, genuineness, and unconditional positive regard.
From this perspective, psychological distress may occur when there is a gap between the real self and the ideal self. A person who feels they must constantly meet other people’s expectations may become anxious, depressed, or empty. The problem is not only symptom severity but also loss of meaning and authenticity.
Humanistic approaches are especially helpful in understanding:
- Low self-esteem
- Identity confusion
- Alienation
- Feelings of emptiness
- Lack of personal growth
The main contribution of the humanistic model is that it reminds psychology that people are not only collections of symptoms. They are meaning-making beings whose wellbeing depends on dignity, purpose, and relational acceptance. Its limitation is that it is less specific about diagnosis and may be difficult to test in a strict scientific sense.
4.2 The existential model
The existential model overlaps with humanistic psychology but focuses more directly on life’s unavoidable realities, such as:
- Freedom and responsibility
- Isolation
- Death
- Meaninglessness
- Authentic choice
According to existential thinking, anxiety is not always a sign of disorder. Some anxiety reflects an honest confrontation with the realities of human existence. Abnormality may appear when a person avoids these realities completely and lives in a state of deep inauthenticity or despair.
This model is useful in work with clients experiencing grief, emptiness, trauma, or identity crises. It helps explain distress that arises when life feels meaningless rather than when there is a specific symptom cluster. In exam writing, it is enough to show that existential theory shifts the focus from “what is wrong with you?” to “what meaning are you able to create in difficult circumstances?”
4.3 The sociocultural model
The sociocultural model argues that abnormal behaviour is shaped by social structures, relationships, and cultural expectations. It pays attention to:
- Family systems
- Peer influence
- Gender roles
- Poverty and inequality
- Discrimination
- Violence and trauma
- Social support
- Community norms
This model is especially important in South African psychology because social inequality, historical disadvantage, and structural violence can contribute to distress. A person’s symptoms may be strongly influenced by unemployment, housing insecurity, racial discrimination, gender-based violence, or community instability. Such stressors do not merely “trigger” symptoms; they can shape the course of disorder over time.
The sociocultural model also helps explain why rates of disorder differ across groups. Such differences may reflect variation in stress exposure, access to care, help-seeking patterns, and diagnostic bias. For example, women are often diagnosed with depression and anxiety more frequently than men, partly because of social roles, reporting patterns, and clinician expectations. Likewise, some groups may be underdiagnosed because of stigma, language barriers, or cultural mismatch with clinical systems.
4.4 The biopsychosocial model
The biopsychosocial model is not a competing theory in the same narrow sense as the others. Rather, it is an integrative framework that combines biological, psychological, and social influences. It is particularly helpful because most disorders have multiple causes and maintaining factors.
For example, consider major depressive disorder:
- Biological factors may include family history, sleep disturbance, or neurotransmitter dysregulation.
- Psychological factors may include negative thinking, helplessness, and poor coping skills.
- Social factors may include loss, conflict, poverty, or isolation.
None of these alone fully explains the disorder. Together, they create a more realistic picture. The same logic applies to anxiety disorders, substance use disorders, and trauma-related disorders.
The biopsychosocial model is often the best answer in comprehensive essays because it avoids reductionism. It does not say that everything is caused by biology, psychology, or society alone. Instead, it shows how these dimensions interact over time. Its limitation is that it can become too broad if not applied carefully. To remain useful, it must be linked to specific evidence and mechanisms rather than offered as a vague slogan.
4.5 Comparative summary
| Model | Main emphasis | Key question | Typical strength |
|---|---|---|---|
| Humanistic | Growth, self-concept, meaning | Is the person becoming their true self? | Emphasises dignity and authenticity |
| Existential | Meaning, freedom, isolation | How does the person confront existence? | Helps with grief, emptiness, identity issues |
| Sociocultural | Social environment and culture | What social forces shape distress? | Explains context, inequality, and stigma |
| Biopsychosocial | Interaction of multiple levels | How do body, mind, and society interact? | Integrates several explanations |
In many exam situations, the strongest response is to use the biopsychosocial model as a unifying framework after describing the individual models. This shows depth and avoids the mistake of treating abnormality as one-dimensional.
5. Comparing the Models, Evaluating Them, and Writing Strong PYC3702 Answers
A high-quality PYC3702 response does more than list models. It evaluates them, compares them, and shows how they apply to real cases. This final section brings the ideas together in an exam-friendly way and highlights the kinds of arguments that usually earn strong marks.
5.1 How the models differ in what they explain
Each model answers a different question:
- The supernatural model asks whether the cause lies beyond the natural world.
- The biological model asks whether the cause lies in the body or brain.
- The psychodynamic model asks whether the cause lies in unconscious conflict and early development.
- The behavioural model asks how the disorder was learned and maintained.
- The cognitive model asks how distorted thinking shapes emotion and behaviour.
- The humanistic/existential models ask how meaning, selfhood, and authenticity are disrupted.
- The sociocultural model asks how society, culture, and relationships shape distress.
- The biopsychosocial model asks how all of these levels interact.
This means the models are not simply competing descriptions of the same thing. They look at different layers of experience. A person with panic attacks might have a genetic vulnerability, a learned fear response, catastrophic thoughts, family stress, and a lack of social support. Different models highlight different parts of that story.
5.2 Strengths and limitations in a balanced evaluation
A strong evaluation usually notes that every model has both value and limits.
5.2.1 Supernatural model
- Strengths: culturally meaningful, emotionally coherent for believers, can reduce guilt.
- Limitations: not empirically testable, can delay treatment, may intensify stigma.
5.2.2 Biological model
- Strengths: scientifically measurable, supports medication and neuroscience, reduces moral blame.
- Limitations: can be reductionistic, may ignore life context, not all disorders have simple biological markers.
5.2.3 Psychodynamic model
- Strengths: includes unconscious processes, childhood, symbolic meaning, and depth.
- Limitations: difficult to test, can overgeneralise childhood conflict, treatment may be long and costly.
5.2.4 Behavioural model
- Strengths: clear and observable, strong treatment implications, widely supported in learning research.
- Limitations: limited attention to thoughts and meaning, may not fully explain internal experience.
5.2.5 Cognitive model
- Strengths: explains interpretation and appraisal, strong evidence base, clinically practical.
- Limitations: may underplay emotion and biology, causal direction is sometimes unclear.
5.2.6 Humanistic/existential models
- Strengths: emphasise meaning, empathy, growth, identity, and dignity.
- Limitations: less precise diagnostically, weaker empirical specificity.
5.2.7 Sociocultural model
- Strengths: contextualises distress, explains inequality and stigma, essential in diverse settings.
- Limitations: may not explain individual differences fully without other models.
5.2.8 Biopsychosocial model
- Strengths: integrative, flexible, realistic, highly useful in practice.
- Limitations: can become too broad unless specific mechanisms are identified.
5.3 Applying models to a case example
A useful way to study the models is to apply them to one case. Consider a hypothetical UNISA student named Naledi, who has become increasingly withdrawn, sleeps poorly, loses interest in classes, and feels hopeless after repeated academic failure and family conflict.
- Biological explanation: Naledi may have a family history of depression or disrupted sleep patterns affecting mood regulation.
- Psychodynamic explanation: she may be reactivating earlier conflicts about approval, failure, or worthiness.
- Behavioural explanation: withdrawal reduces short-term stress, but this avoidance removes positive reinforcement and worsens depression.
- Cognitive explanation: she may interpret setbacks as proof that she is incompetent and doomed.
- Humanistic explanation: she may feel estranged from her true self and blocked from growth.
- Sociocultural explanation: financial pressure, family expectations, and environmental stress may intensify her symptoms.
- Biopsychosocial explanation: all of these together may maintain her distress.
This example shows why one model alone is rarely sufficient. If an exam question asks for the most comprehensive explanation, the biopsychosocial perspective is usually strongest, provided it is supported by concrete details.
5.4 Common exam pitfalls
Students often lose marks by making avoidable mistakes. Common problems include:
-
Using only one model for a complex disorder
This makes the answer narrow and unrealistic. -
Confusing normal distress with abnormality
Not all sadness, fear, or anger is pathological. -
Ignoring culture
A good answer always notes that context matters. -
Listing models without evaluation
Examiners usually want comparison, not memorisation alone. -
Treating theories as mutually exclusive
In practice, models often complement one another. -
Giving treatment without explanation
Treatment should follow logically from the model.
5.5 How to structure an essay answer
A strong essay on models of abnormality can be organised like this:
- Introduce abnormality
- Define the concept carefully.
- Mention the difficulty of defining it.
- Describe the main models
- Supernatural
- Biological
- Psychodynamic
- Behavioural
- Cognitive
- Humanistic/existential
- Sociocultural
- Biopsychosocial
- Compare their assumptions
- Cause
- View of the person
- Treatment implications
- Evaluate strengths and weaknesses
- Scientific support
- Cultural relevance
- Practical usefulness
- Conclude with integration
- Most disorders require a multi-factor explanation.
5.6 Key revision table
| Model | Core idea | Best use | Main caution |
|---|---|---|---|
| Supernatural | Abnormality caused by non-natural forces | Understanding beliefs and cultural interpretations | Not scientifically testable |
| Biological | Abnormality linked to brain, genes, and physiology | Disorders with strong medical components | Can reduce complex lives to biology |
| Psychodynamic | Unconscious conflict and childhood experience | Explaining repeated patterns and symbolic symptoms | Difficult to verify empirically |
| Behavioural | Learned maladaptive behaviour | Phobias, avoidance, habit patterns | May ignore inner meaning |
| Cognitive | Distorted thoughts and beliefs | Depression, anxiety, stress reactions | Thinking is not the whole story |
| Humanistic | Blocked growth and authenticity | Identity, self-worth, meaning | Less precise diagnostically |
| Existential | Struggle with freedom, death, isolation, meaning | Grief, emptiness, crisis of purpose | Less symptom-specific |
| Sociocultural | Social and cultural forces shape distress | Inequality, trauma, stigma, family context | Can understate individual factors |
| Biopsychosocial | Multiple interacting causes | Most disorders in realistic clinical practice | Too broad if left vague |
5.7 Final synthesis for PYC3702
The study of abnormality in PYC3702 is not just about memorising theories. It is about understanding that human suffering is multi-layered. Some models explain the body, some explain learning, some explain thought patterns, some explain meaning, and some explain social context. No single model completely captures the complexity of mental disorder. That is why modern psychology increasingly favours integration.
In South African and UNISA contexts, this is especially important because mental health cannot be separated from history, inequality, culture, and access to services. A good student answer should therefore show sensitivity to both theoretical and practical realities. It should also avoid simplistic labels and instead demonstrate that abnormal behaviour is best understood through careful, evidence-based, and context-aware analysis.
The most important takeaway is that models of abnormality are not merely academic categories. They shape diagnosis, treatment, stigma, and the way society responds to suffering. For that reason, mastering them is essential not only for passing the module, but also for developing a responsible psychological perspective.
6. Quick Revision Checklist and High-Yield Summary
6.1 What to remember first
If time is short before an exam, focus on these core points:
- Abnormality is not defined by one rule.
- Culture and context strongly shape what is considered abnormal.
- The major models each explain a different part of psychological distress.
- The biopsychosocial model is often the most complete framework.
- Good exam answers compare, evaluate, and apply models to examples.
6.2 One-sentence summaries of each model
- Supernatural: abnormal behaviour is caused by supernatural forces.
- Biological: abnormal behaviour is caused by brain, genetic, or physiological factors.
- Psychodynamic: abnormal behaviour reflects unconscious conflict and early experience.
- Behavioural: abnormal behaviour is learned and maintained by reinforcement or conditioning.
- Cognitive: abnormal behaviour is driven by distorted thinking and faulty interpretation.
- Humanistic: abnormal behaviour arises when growth and authenticity are blocked.
- Existential: abnormal behaviour reflects struggles with meaning, freedom, and isolation.
- Sociocultural: abnormal behaviour is shaped by social pressure, culture, and inequality.
- Biopsychosocial: abnormal behaviour results from interacting biological, psychological, and social factors.
6.3 Final exam-friendly conclusion
A strong understanding of models of abnormality requires more than memorising definitions. It requires recognising that psychological disorders are complex and that each model reveals only part of the picture. The best answers show balance, critical thinking, and sensitivity to context. In PYC3702, that means demonstrating that abnormality is best understood through an integrated perspective that respects biology, learning, thinking, meaning, and society alike.
