When normal psychology goes wrong .. this is how we understand the normal
What makes a thought of behaviour abnormal?
What is a mental disorder?
How do we determine who has a mental disorder is in need of treatment?
There are so many circumstances which we think are abnormal, but possibly in another culture is perfectly normal.
But is there a time where something is universally abnormal?
Case: wayyy back in the 1700’s a guy thought the french had magnetised the air he breathed, and they were controlling his body
Defining abnormality is difficult!
But there are 4 key characteristics to determine whether a thought or behaviour is ‘abnormal’ → note there are limitations to this.
statistically infrenquent in the population
any deviation from the form is ‘abnormal’
limitation: not all statistically infrequent mental characteristics are ‘anmormal’
e.g like Einstein, even though his brain in statistically abnormal, you won’t treat him for abnormal behaviour
Beethoven, again, musical genius and you woulnd’t treat him to mak ehim ‘normal’
Violates social norms
limitations:
e.g what is concered socially acceptable ochanges over time e.g homosexuality was considered a mental disorder until 1973
nothing has changed about being gay between then and now LMAO, just the perception of what is okay has changed.
what is socially acceptable differs between cultures
Cause distress
abnromal thoughts / behavious cause distress
most mental disorders are associated with distress
limitations:
distress is normal in some situations (e.g grieving or trauma)
some widely acceted psychopathologies are not associated with distress e.g mania, psychopathy
Case impairment
in an individuals ability to function
socially, occupationally, personally
e.g you drunk so much taht you can’t get to work, or you can’t public speak even if your job is lecturing.
limitation:
asperger’s disorder (now classified as the autism spectrum)
apparently the room full of guys at nasa who just sent people to the mood all tested positive for autism
Abnormal thoughts and behaviours tend not to occur in isolation
instead they tend to occur in distinctive clusters
hallucinations and delusions tend to co-occur
obsessions and compulsions tend to co-occur
negative mood and flat affect and loss of energy and sleep difficulties tend to co-occur, no motivavation
A mental disorder is a distinct and recognizable cluster of abnormal thoughts and behaviours
Some history: Mental disorders used to be clustered together as ‘you’re mad’, or
Big brain guy: Emile Kraepelin
was the first to classify types of mental disorders based on systematic empirical observations
before him, there was little agreement on what constituted a mental illness
he offered diagnostic categories defined by common patters of symptoms.
Van Gogh: bipolar disorder
Janice Joplin: substance abuse (also mental disorder)
Churchill: Depression (the black dog of depression) → the black dog institute
Kraeplin’s system - mental disorders are separate entities
that is, for any given mental disorder, you have it or you don’t
that might seem obvious but sometimes its hard to spot, as many mental disorders are just extreme versions of normal behaviour
e.g clinical anxiety seems to differ from normal enxiety in severity, duration, degree of impairment etc. not but in quality
for this purpose we need to draw the line between NORMAL and ABNORMAL
At this point a dimension become a category
Clinical diagnosis and the DSM
8 the major diagnostic system used bt psychoogisis is the Diagnostic and Statistical mnaual of Mental Disorders (DSM)
operates on a categorical approach
if you fulfill criteria, you have the mental disorder
in some ways, they make the rules as to whats normal and abnormal
the major alternative classification is the International Statistical Classification of Diseases and Related Health Problems (ICD-10)
more popular in europe and america
Case: Formerly known as Multiple-personality disorder or now DISSOCIATIVE IDENTITY DISORDER (DID)
known as split personality
characterised but he presence of two or more distinct personality states and memory variations
each alter has access to only a subset of memories
this is quite controvertial
Case: Eve and her 3 personalities
#1: Eve White, Eve Black and uhh
They had different memories, and weren’t aware of each other’s existence
She could control the switching
Food for thought:
there were 183 mental disorders, but now there are over 300
which mental disorders exist in reality???
