4Ds
- Danger - to oneself or to others
- Deviance - violations of society's ideas about normality
can change as societal norms change e.g. homosexuality - Distress - experienced by person or the family
can be quite subjective - Dysfunction - distortion of perceptual or cognitive functioning
Early European views
Believed abnormal behaviour was a consequence of spirits or Gods (supernatural forces)
Arguments such as good vs evil, God vs Devil
Augmented by public fear and anxiety - harder to challenge
Treated with exorcism, trephination
Greeks and Romans
Beliefs based on Babylonian ideas
Greeks started naming and describing disorders
Hippocrates made link between brain and mental illness
However, thought it was due to an imbalance of bodily fluids
Tried to treat mental problems by dealing with physical issues
Supportive atmosphere, music, massage exercise, baths, sobriety, vegetarian diet
Middle Ages
Plagues, wars,uprisings caused by the Devil
(Almost went backwards in terms of thinking)
Witch trials
Medical view started reappearing at the end of the middle ages
Renaissance
Asylums - hospitals and convertedd monastries
Started as a way of treating, became twisted, stigmatised (e.g. Bedlam)
Pilgrimages
Reform
Starting treating 'mentally ill' with care, respect and dignity
Pinel - campaigned to unchain patients
Psychiatrists were called 'Alienists'
Phrenology, coma therapy, lobotomies
As recoveries dwindled, prejudices emerged
Models
Conceptual models = frames of reference, provide a way of understanding and explaining behaviours
Have a basic aetiological assumption or hypothesis about a phenomenon
Develop when there is a consistency in types of behaviours which require an explanation
Models may persist due to plausibility, or advocates maintaining belief in it
/ Increases resistance to other views - once accepted by large population, very difficult to propose alternative views
/ Affect who is identified as abnormal, what criteria is used, the treatment, public attitude, types of institutions used
Psychodynamic Approach
Mind made up of Id, Ego and SuperEgo - mental illness caused by internal struggles, imbalance
Unpleasant thoughts, impulses and wishes are repressed - causing psychological issues
Transformed into dreams, which can be interpreted
Defense mechanisms
- Denial - motivated forgetting of distressing experiences
- Identification with the aggressor - adopting the psychological characteristics of people we find threatening
- Rationalisation - providing reasonable sounding explanations for unreasonable behaviours
- Regression - returning psychologically to a younger, safer time
- Repression - motivated forgetting of emotionally threatening memories or impulses
* Helped to understand abnormal functioning is rooted in same processes as normal functioning
/ Relies solely on case studies
/ Fails to establish guidelines
/ Little support for this approach
Humanistic Approach
Treat patients with unconditional, positive regard
Dysfunction is caused by self-deception (gap between ideal self and real self)
When overwhelmed, we conform excessively, looking to others, which builds resentment
Abdicating responsibilities leads to emptiness, inauthenticity, anxiety, frustration, alienation, depression
* Optimistic
* Patients have potential yet to be fulfilled / May place (too much) responsibility on patient
Behavioural Approach
Abnormal behaviour is learnt, the same as any behaviour
Classical conditioning - process of learning by temporal association
Operant conditioning - process of learning by reinforcement
* Can be tested
* Easier to treat than identify actual cause
*/ Helps people to think in different ways
/ Actual behaviour doesn't always follow basic principles
Cognitivism
Cognition = mental processes of perceiving, recognising, conceiving, judging and reasoning
Cognition is the centre of thought, emotions and behaviour
Upsetting or automatic thoughts, intrusive thoughts = abnormal thinking
Maladaptive or irrational assumptions guide thoughts that lead to less happiness
Illogical thinking processes
1. Selective perception - noticing when someone is negative towards you, but not positve
2. Magnification - exaggerating the scale of the problem
3. Overgeneralisation - thinking a problem is broader than it is
* Can be tested, but mostly requires introspection
* Shown to be effective with depression, anxiety and sexual disorders
/ Narrow scope
Biological
Caused by organic defects - Behavioural genetics, genetics, biochemistry, neurotransmitters
GABA, Dopamine, Norepibephrine, Serotonin - the neurotransmitters usually affected
Treatment usually includes psychotropic drugs
Psychoadtive drugs change neurotransmitter activity
* Helpful for range of issues
*/ Doesn't preclude any psychological interventions
/ Questions whether biology causes psychology or vice versa
Some genes have stronger links to mental illnesses (reciprocal gene-environment interaction?)
May predispose people to seek out situations that increase likelihood of disorder
Could use gene therapy in the future
Sociocultural Model
Links abnormal psychology to social class - patterns show various in different cultures
Societies undergoing major change usually show higher numbers of mental illness
Prejudice and discrimination based on race, sex or age makes health and life satisfaction harder
/ Research sometimes inaccurate or difficult to interpret
/ Studies failed to support predictions
/ WEIRD
Diasthesis-stress model
No model is consistently superior to others
All factors are relevant
There are predisposing (genes) and precipitating factors (experience)
Predisposition + environmental stressors --> development of disorder
Environmental stressors = prenatal trauma, abuse, family conflict, significant life changes
Medical Disease Model
Stout, 2004
Mentally ill seen as incapable of caring for themselves
Institutionalised programmes diagnose and treat disorders
Mentally ill receive care in hospitals and are seen by specially trained staff
Funds allocated to communities - build institutions, train staff, support research
Model often assumes that there is a connection between physical and mental diseases
Assumes pathological processes are genetic, biophysical or psychogenic
Genetic Model
Heredity - acknowledged as important determinant of biological and psychological make-up
1. Hereditary disposes people to act in a certain way
2. Genetic factors are primary or exclusive determinates
Some genes have stronger links to mental illnesses (reciprocal gene-environment interaction?)
May predispose people to seek out situations that increase likelihood of disorder
Genetic contribution provide te conditions that could alloe psychopathy to occur
Environment can play factor in probability of triggering the disorder
Could use gene therapy in the future
- Family-risk method
Greater relationship between trait and closeness of blood ties, the higher the incidence of trait - Pedigree method
May uncover tentative relationships - Twin study
Can determine genetic vs environmental effects
Genetic Model 2
- Adoption studies
Compares children who have different genetics but same foster home
If incident rate of disorder is higher, genetic transmission can be inferred
Environmental influence important, but genetic structure determines behaviour
Genetic transmission, enzymatic control, mutative effects
Genetic vulnerability - biological characteristics interact with noxious environment
Biochemical Model
Characterised by quest for toxic agent which is necessary and sufficient to produce mental illness
Genetics could be responsible for aberrant structures or changes in neurochemistry of neurotransmitters
(used for communication and mediation in CNS)
Current emphasis on identifying deficiencies in neurochemistry
Imbalance of monoamines --> schizophrenia??
Elevated levels of dopamine and norepinephrine metabolites found in schizophrenia patients
Strong links of hyperactivity and childhood psychosis
Assumption that descriptive differences in peripheral measures have aetiological implications
Ethical considerations have prevented direct experimental measures
Poor diagnostic agreement
Neurophysiological Model
Assumes aetiology of abnormal behaviour is in brain structures that are inherited, congental or acquired
Defects, insults or damage the brain provide physical basis for disordered thinking and behaviour
Brain lesions caused by cooling, radiation, electrolysis or chemical means have been used for studies
Can't go round putting in lesions (ethics) but can use those who have lesions for epilepsy
Can use electrical stimulation for investigations
Can cause extra tissue damage
Need to consider the intensity of stimulation
EEG records electrical activity of the brain by uing elctrodes
Not useful for diagnosing psychiatric conditions
Can measure cerebral activity evoked by sensory stimulation (associated with psychopathology)
Diagnostic inaccuracies, confounding effects of institutionaliztion, incomplete understanding
Contingent Negative Variation
Cortical response associated with attention
Marked by slow rise in negative potential when anticipating presentation of stimuli
Thought of as reflecting a transitory state of increased arousal, terminated after response is made
Skin conductance can be used to measure brain activity
measures the change in skin resistance as a result of sweat-gland activity
Psychoanalytic Model
Freud - Every human act occurs as a function of prior mental events and not chance
Anxiety stems from fear of punishment for expressing instincual drives, guilt for not following societal norms and dangers of real world
Tension state determined by external factors - danger signal and motivator to reduce stress
Relationship between ego and id gives rise to neurosis
Little empirical support for this model
Carl Jung - collective unconscious
Abnormal behaviour = inability to integrate personality
Alfred Adler - environment and social factors
Abnormal behaviour = inferiority complex
Harry Stack Sullivan = disordered interpersonal relationships
Environmental Model
Focuses exclusively on external variables as determinants for abnormal behaviour
Believe in potenc of cultural mores, social systems, economic influences, unique life experience
