Neologism
I
am here from a foreign university..
And you have to have a plausity of all
acts of amendment to go through for
the children’s code…it is an amorition
law… there is nothing to disturb me…
it is like their privatilinia.. And the
children have to have this accentuative
law so they don’t go into the mortite
law of the church (Vetter, 1969)
Loose Associations
 The
problem is insects…My brother
used to collect insects...He’s a man 5
foot and 10 inches... You know, 10 is my
favourite number… I also like to dance,
draw, and watch television

are you feeling:

 The
weather:
– So hot, you know it runs on a cot
Perseveration

again
words and statements again and
Blocking

I may be thinking quite clearly and tellling
someone something and suddenly I get stuck.
You hve seen me do this and you may think I
am just lost for words or that I have gone into
a trance, but that is not what happens. I
suddenly stick on a word or an idea in my
head and I just can’t move past it. It seems to
fill my mind and there’s no room for
anything else. This might go on for a while
and suddenly its over.
Disorganized Speech
 Word
Salad: complete breakdown of
associational process
– Its all over for a squab true tray and there
ain’t no music, there ain’t no nothing
besides my mother and father who stand
alone upon the Island of Capri where there
is no ice, there is no nothing.

Delusion of Control

The inmates here hate me because I am

The voices…were mostly in my head, though
I often heard them in the air or in different
parts of the room. Every voice was different
and each beautiful and, generally, speaking
or singing in a different tone and measure
and resembling those of relations or friends.
There seemed to be many in my head. I
should say upwards of fourteen. I divide
them as they styled themselves, or one
another, into voices of contrition and voices
of joy and honour.
