Abstract
A simple conditioning method, using cards for control of attention, was tried out on 6 severely retarded children (CA 6:4–15:11, MA 2:11–4:3, IQ 22–47). After 17 workdays the three “high-MA” Ss discriminated 8 to 10 words out of 10 and 9 to 10 words 24 and 48 days later (with 50 to 100% transfer to smaller, different print). “Low-MA” Ss retained 10 to 40% (40% for the one S without speech).
