psychopathology (mocks) Flashcards
behavioral characteristics of depression
change in activity levels - fatigue insomnia change in appetite - weight loss aggression self harm withdrawn and irritable
deviation of social norms
concerns behaviour that is different from the accepted standards of behaviour in a community or society.
explicit = laws
implicit = expectations
e.g. an individual with anti-personal disorders - explicit stealing, implicit lying
failure to function adequately
occurs when someone is unable to cope with ordinary demands of day to day living independently in society
show signs of personal suffering or stress (viewers distress)
e.g a depressed individual struggling to go to work or having self care
statistical infrequency
occurs when an individual has a less common characteristic
they are minority
eg. obtaining an IQ of 70 or less = intellectual disability disorder
deviation from ideal mental health
occurs when someone doesn’t meet a set criteria for good mental health.
- positive view of yourself
- capable of personal growth and self-actualisation
- being independent
- accurate view of reality
- able to resist stress
- being able to master your environment
the two process model of phobias
Mowrer - developed - learnt through classical conditioning and maintained through operation conditioning
classical conditioning = associate two stimuli -
don’t fear = NS, something that triggers fear= US, association formed= CS, phobia = CR
Watson and Rayner - little albert
aim - to see if a phobia can be developed through classical conditioning
method - 11 month old Albert, showed various objects that he didn’t respond to including a white rat.
- then the started to cause a loud noise by Albert head when he saw a rat 3 times to startle him.
results - albert start to show a phobia toward rat and other objects that looked like rats. - phobias can be developed through classical conditioning and they are generalized to other objects
operant conditioning - phobia maintance
negatively reinforced - behavior is strengthened when the negative consequence is removed
- also the reduction in anxiety
- meaning they are more likely to repeat the behavior in the future - avoidance
strength of the two process model of phobias - research support
Watson and Rayner - demonstrated the process of classical conditioning in the formation of phobias with little albert.
this show support to classical conditioning involvement in phobia and the generalization can occur to other phobia stimuli
however this research is a case study so it is hard to generalize the results as it is an unique case.
strength of the two process model of phobias- application
behaviorists ideas can be applied to the treatment of phobias
systematic desensitization - help unlearn their fears
or flooding - stop the negative reinforcement
therapies have been successfully treat phobias, providing further support for the effectiveness of the behaviorists explanation
a weakness of the two process model of phobias - ignore other factors
ignore the role of cognitive process in the development of phobias
such as irrational thinking leading phobias not just learning it.
e.g. claustrophobia maybe cause by thought like I will suffocate
furthermore, CBT treatment are more successful in treating phobias than the behaviorists treatments. - combination of both may cause phobias.
define neurotransmitter
chemical messengers which covey information between neurons
the neural explanation of OCD - neurotransmitters
serotonin - role in sleep, memory, emotions, appetite and social behaviors
- believe to play a role in preventing repeating tasks
- low levels of serotonin led to OCD
dopamine - associated with motor functions and pleasure/ impulsive behavior
- high level of dopamine led to OCD
the neural explanation of OCD - brain structure
serval areas in the frontal lobe affect the development of OCD - abnormal brain circuit
2 areas = the basal ganglia and orbitofrontal cortex
basal ganglia = cluster of neurons, one role - coordination of movement (brain injurie = OCD)
orbitofrontal cortex = converts sensory information into thoughts and actions - PET scans show high levels activity in OCD brains. - high level led to compulsions
worry circuit - candidate nucleus and thalamus - impulses
strength of the neural explanation - research support
research support - abnormality in brain structure leds to OCD
metanalysis of OCD studies that used brain scans and neuro imaging techniques
found consistent evidence of an association between the OCF and OCD
the meta-analysis didn’t suggest a reason for the abnormalities in the OCF functions and that it can be the result of abnormal neuroanatomic development or a failure of synaptic pruning
