Abstract: | Summary A PDP-8/S digital computer has been used to produce a psychological test—Rabbitt's test of selective attention —which consists
of packs of cards with varying numbers of letters, some of which are classified as relevant and some as irrelevant. Central
processing ability is assessed by timing the sorting of the cards on the basis of the relevant information, the irrelevant
information being ignored. The program both chooses and positions the symbols randomly and the prints the card face on its
Teletype output. A flow diagram of the program and details of the random number generator are described. The use of the computer
for this purpose has reduced the time taken to produce one pack of cards by a factor of at least 10. Further developments
of the technique are discussed. |
