Holly is a developmentally disabled child and is working with a therapist who is training

Holly to write her name.

The training procedure consists of gripping the pencil properly,
followed by simple strokes with the pencil, then by combining strokes into simple patterns
that more and more closely resemble the letters in Holly's name. The therapist is careful to
provide praise as Holly lengthens the sequence of responses. This procedure is referred to
as
a. shaping.
b. unit collection.
c. specialization training.
d. response partitioning.
e. response gradation.
