IWad ~108tar 6tbt6mant6 of what we want it to ~1~1oura and the condition8
under aiich it owe do ito job. For a given aiammxwnt task w4 may nsed
4 toot which yield8 89% perfect @core4 , or one that nsbodp parscoo ualeoo

to get out 4nd do more, better, 4nd Cantor? Do you want 4 toot that is
basically a teaching dcvica? That wa4 the initial motivr~tion of S. I..

Anothsr quartion io *How rapidily and under whet cmditicmn do tsot ocoreo

be noted that people oeeking counoelfag are parh:?o leoot stable in ouch

more knowledge 4bout thfr queetion not only in toner of tho teat, but 4140
the intervening aventr. In measuring how wall 4n electronic6 technician

In being here tonight, I have triad to point to 4om3 of the future
and to � tir up your thinking. I hove tried to illurtrata the l’taot’@ 40 4
sample of behavior. I w4nt to cheer for axtending 4nd trying out new concapto
of 4n8wer pattarnr in tart fonnulatfon. I want to iace ue devalop the
ure of computer6 to do things in test rcoring and teat analyrfa th4t wo
hove only tolked or drarsled 4bout and to do � ome thing4 that wa h4ve not
avan rtartad to inugine. Keep your w4ys and maano, your rechniques, in
proper peropectiva; and keep in front of you a clsrr idea of the purport4
of the test itself by defining it4 uoeo, 48 well as ftr limft4tion4, 4nd;
through these, extending Its ueefulneoo a8 a me4euring device or w4y of
drawing more 4dequ4te, 4nd more effective samples of behavior.
