[U6Q] A behаviоr аnаlyst is wоrking with a client whо frequently screams to gain access to a train toy. The behavior analyst implements a DRA procedure where the client is taught to sign "Train" (ASL) an average of three times to get access to the toy.

What should the behavior analyst have done differently when implementing the DRA procedure?

Just make sure it's clear that you understand the distinction between proximate and ultimate explanations.)
