wants, we conduct correspondence checks. Once the learner achieves 80% or
above with an array, increase the array size by one symbol.
1. *CP shows available reinforcers and their position relative to each other (at
the beginning of the trial and any time new items are available). Then, CP
physically guides the learner's hands to touch each symbol (as in previous
phases, quality of touch is important, and the symbols are always shown
from top to bottom and left to right.)
2. The learner gives CP a symbol to communicate their choice.
3. CP presents all available items and says, "go ahead", "take it", etc. but does
not name the item the child gave the symbol for!
4. Provide verbal praise for touching correct item, but only name the item when
they pick it up.
5. If the learner goes for any item other than the one, they gave the symbol for,
block access and initiate the four-step error correction.
6. Rearrange order of symbols before each new trial. Once learner achieves
80% correct, increase the array size (up to six items at a time.)
