you  to  arrange  these  cards  (holding  out  sample  set)  like
this:  those  that  have  X  and  Y  on  them  go  here  (pointing
to  appropriate  corner  of  large  cardboard  and  laying  down
the  card)  where  it  says  X  —  Y;  those  that  have  X  and  K
on  them  go  here,  where  it  says  X  —  K  (laying  down  the
cards  which  contain  X  -  K);  those  that  have  5  and  6  on
them  go  here;  and  those  that  have  none  of  these  combinations ­
  here,  where  it  says  other.  Now  (picking  up  the
sample  set  and  handing  it  to  subject)  try  it  with  these
cards.”
“Now  do  the  same  thing  with  these  cards  (handing  subject ­
  the  large  pack).  Do  it  carefully  and  quickly  but  do
not  rush.  All  right?  Start.”  Allow  subject  to  finish.
Record:  Sort  back  cards,  counting  all  mistakes.  Record  number ­
  of  test,  number  of  seconds  taken,  number  of  mistakes
made.  E.  g.,  12;  84  —  2.
Rating:  Apply  formula  II.  Point  of  reference  is  50  cards  correctly ­
  sorted  in  80  seconds;  RU,  50,  the  total  number  of
units  in  the  test;  Ru  or  reference  time  per  unit  is  80  -5-  50
or  1.6;  E,  errors,  to  be  counted  double;  T,  time  taken.
Applying  this  formula  to  the  sample  record  above,
1.6  X  50  -  4

Description:  This  test,  because  of  its  nature,  is  given  under
instructions.
Instructions:  “I  am  going  to  give  you  a  number  of  directions
so  listen  very  carefully  and  do  exactly  what  I  tell  you  to.
For  instance,  I  might  ask  you  to  fold  this  sheet  of  paper
twice  and  then  write  your  name  near  the  top,  like  this,
(examiner  demonstrates).  Be  sure  to  listen  carefully  each
time  and  as  soon  as  I  stop  talking  do  exactly  what  I  say.
Are  you  ready?”  The  examiner  then  proceeds  to  give
the  following  series  of  directions  which  he  has  carefully
