Bina has been diagnosed with depression. Her doctor says that depression is a common problem but
Bina is miserable. She cannot be bothered to get washed in the morning and her manager is unhappy
that she is taking a lot of time off work. When she does go to work she is irritable, has temper tantrums
and is rude to customers.
Using your knowledge of three definitions of abnormality, explain whether or not Bina's behaviour
might be considered to be abnormal. [6 marks] - Answer--Statistical infrequency - the doctor says
depression is quite common therefore Bina's behaviour should not be considered abnormal.

Deviation from ideal mental health - Bina is miserable therefore her behaviour could be considered
abnormal.
Deviation from social norms - Bina has temper tantrums/is rude to customers which is not the norm for
adults in a work environment therefore her behaviour could be considered to be abnormal.

How might the biological approach be used to explain Bob's obsessive-compulsive disorder? [4 marks] -
Answer--Neural explanations (neurochemical and neurophysiological) is why Bob is having a scan:
The basal ganglia and other circuits have been implicated suggesting that disturbed communication in
these structures might account for the repetitive behaviours seen in Bob's OCD. Also, OCD linked to
abnormality/excessive activity in the orbital frontal cortex/thalamus; abnormal functioning of the
parahippocampal gyrus - related to the regulation of unpleasant emotions.
