Behaviour doesn't align with societal expectations, e.g. antisocial personality
Failure to function adequately
Unable to cope with the ordinary demands of life, e.g. intellectual personality disorder, danger to themselves
Definitions of abnormality vary depending on culture, situation and age, and are flexible and observable
Defining abnormality based on deviation from social norms or failure to function adequately can lead to negative labelling and be discriminatory and subjective
Classical conditioning
Acquiring phobias through association of a neutral stimulus with an unconditioned stimulus that elicits fear - Pavlov
Operant conditioning
Maintaining phobias through consequences, such as negative reinforcement of avoidance behaviour - skinner
The behaviourist approach has limitations in fully explaining phobias, as not all phobias stem from direct traumatic experiences and some may have an innate basis
Systematic desensitisation
Gradual exposure to the feared stimulus (anxiety hierarchy) while using relaxation techniques (reciprocal inhibition) to overcome the phobia and form a new conditioned response
Flooding
Immediate and prolonged exposure to the most anxiety-provoking aspect of the phobia to extinguish the fear response (worn out) to form a new association as unable to avoid
exposure therapies for phobias can be effective, but have limitations such as requiring patientwillingness and consent, and potential ethical issues - high dropout rate
Beck's negative triad
Negative thoughts about the world, self and future leading to cognitive biases and negative schemas (information interpretation) - caused by faulty information processing
Ellis' ABC model
negative thoughts (Activating event) leads to irrational beliefs which result in negative emotions (consequence)
The cognitive approach highlights the role of faulty information processing and irrational thoughts in depression, but does not fully explain the cause-effect relationship between cognitions and depression - cause or consequence
Cognitive approaches to treating depression can be effective, but have limitations such as requiring patient motivation and overlooking biological and environmental factors
Genetic factors
OCD has a polygenic basis with high heritability rates, suggesting a biological vulnerability - aetiologically heterogenous
Neurotransmitter imbalances
Abnormalities in serotonin and dopamine regulation may contribute to OCD symptoms
The biological approach provides a partial explanation for OCD, as it does not fully account for cognitive and environmental factors that may also play a role
Biological treatments for OCD can be effective in reducing symptoms, but do not address the cognitive and behavioural aspects of the disorder, and may have side effects
statistical infrequency
a behaviour is seen as abnormal if it is statistically uncommon, or not seen very often in society
deviation from ideal mental health
abnormal behaviour should be defined by the absence of particular (ideal) characteristics.
Jahoda proposed six principles of ideal mental health, including having a positive view of yourself and being resistant to stress.
negative reinforcement
something unpleasant or uncomfortable is removed or taken away in order to increase the likelihood of the desired behaviour
positive reinforcement
encouraging a behaviour by offering a reward when the behaviour occurs
punishment
adding an unpleasant thing to discourage a behaviour
phobias - animal extrapolation
more complex than stimulus and response
reductionist
phobias - little albert
link between bad experience and phobia
phobias - jongh
73% who feared the dentist had trauma vs 21% in control
phobias - only explains behaviour
not cognition
irrational beliefs - more than avoidance
incomplete explanation
phobia treatment - gilroy
less fear than control - even 33 months later
phobias treatment - bang
snake phobias - fear rating fell and stayed down 6 months later
phobias treatment - biological
if innate
would require drug therapy
not applicable to all
flooding
cost effective
more people treated (nhs)
depression - cohen
cognitive vulnerability more common in individuals with depression
