Assessment and examination questions
ASSESSMENTS
Activity:
The following examples show neologisms, clang associations, loose associations, and disturbances of effect.
For EXAMPLES 1-3, circle words or phrases in the illustrations given and identify which of the above they are.
In EXAMPLE 2, show the chain of loose connections.
In EXAMPLE 3, suggest a category of Schizophrenia.
Example one:
I am a nun. If that’s not enough, you are still his. That is a brave cavalier; take him as your boon-swagger Caroline; you know well you are my lord because I am bored, and you like a sword in the Fjord. If you are the habbicontin, Mrs K is still best by fear. Handle the gravy carefully. Where is my paintbrush? Where are you, Monet?
Example Two:
“I am writing on paper. The pen which I am using is from a factory called ‘Perry & Co’. This factory is in England. I assume this. Behind the name of Perry Co. the city of London is inscribed, but not the city. The city of London is in England. I know this from my school days. Then, I always liked geography. My last teacher in that subject was Professor August A. He was a man with black eyes. I also like black eyes. There are also blue and grey eyes and other sorts, too. I have heard it said that snakes have green eyes. All people have eyes. There are some, too, who are blind. A boy leads about these blind people. It must be very terrible not to be able to see. There are people who can’t see and, in addition, can’t hear. I know some who hear too much. One can hear too much. There are many sick people in Burgholzi; they are called patients. One of them I like a great deal. His name is E. Sch. He taught me that in Burgholzi, there are many kinds of patients, inmates, and attendants. Then there are some who are not here at all. They are all peculiar people ….”
Example Three
“Carl was twenty-seven years old when he was first admitted to a psychiatric facility; gangling and intensely shy, he was so incommunicative at the outset that his family had to supply initial information about him. It seemed they had been unhappy and uncomfortable about him for quite some time. His father dated the trouble some time back in high school. He reported. “Carl turned inwards, spent a lot of time in his room alone, he had no friends and did no schoolwork.” His mother was especially troubled by his untidiness. He really was an embarrassment to us, and things have not improved since. “You could never take him anywhere without an argument about washing or changing his clothes. And once he was there, he wouldn’t speak to anyone” His parents further reported that after living away from home for three years, Carl moved back. Disagreements between Carl and his family became frequent and intense. He became more reclusive, bizarre, and sloppy. His parents became more isolating and irritable. Finally, they could take it no longer and took him to hospital. He went without resistance. After ten days in the hospital, Carl told the psychiatrist working with him. “I am an unreal person. I am made of stone or else I am made of glass. I am wired precisely wrong. But you will not find the key to me. I have tried to lose the key to me. You can look closely if you want, but you will see more from far away. Shortly after that, the psychiatrist noticed that Carl “…. smiles when he is uncomfortable and smiles more when he is in pain. He cries during television comedies, seems angry that justice is done and is scared when someone compliments him. He roared with laughter on hearing that a child had tragically been burnt. He grimaces often. He eats very little but always carries away food. After two weeks, the psychiatrist said to him,” You hide a lot. As you say, you are wired precisely wrong. But why won’t you let me see the diagram?” Carl answered, “Never will you find the external lever that will sever me forever with my real, seal, deal heel. It is not on my shoe, not even on my sole. It walks away.”

Say whether the symptoms are mainly positive, mainly negative, or mixed.
Mary is 21 and was first presented to the psychiatric services as an out-patient at the age of 19. She gave a two-month history of social withdrawal associated with paranoid delusions. A diagnosis of probable paranoid schizophrenia was made, and she was treated. However, her condition continued to deteriorate. Over the next two months, she became retarded and mute and was admitted to hospital. At this time, she began to have freezing episodes and started to walk backwards. During her freezing episodes, she should stand rigid for hours and ignore any instructions from nurses to move.
Tommy is 41. According to the family, he has always been withdrawn, and his behaviour is sometimes inappropriate. His sister-in-law gave the example of him waking her up in the middle of the night to cook home some breakfast! Over the last year, Tommy has frequently talked at length and has difficulty understanding. He often goes days without speaking to people.
Dave is 24. Over the last three months, he has visions of aliens walking around him when he goes to work. His speech has become rambling, and often, his friends cannot tell what he is saying. A few weeks ago, Dave was told his old college friend had died, and in response, he laughed. He has stopped showering regularly and believes his water system has been poisoned. He has lost a lot of weight as he no longer bothers to cook. His neighbour was worried about Dave when she saw him sitting on the floor in the corner shop grimacing.
Mike is a 33-year-old divorced male with two children he rarely sees, ages 8 and 10. A psychiatrist has never seen him. His family doctor has tried getting him to see a local psychiatrist, but Mike refuses. Mike says he knows someone has removed his brain and replaced it with someone else's. He believes that this brain is controlling him and that he is not responsible for his actions. He works daily and has been in his current job for 15 years. He says he has many friends, but sometimes he thinks one of them did this to him. He is convinced he must protect his brain by wearing a hat (even to bed). He can speak fine and goes to work every day. He doesn’t think his thoughts are unusual.
Susan is 20 years old. She suffered from depression when she was 15. She has now been discharged from her psychiatrist and has been free of depression for the last three years. She is taking her final university exams, has had trouble sleeping, and has experienced bad dreams for the last few weeks. She is feeling stressed out and overwhelmed.
