To achieve momentum during a discrete trial session, what should be done with the discriminative stimuli (SD)?

Delivering the discriminative stimuli (SD) quickly helps to maintain momentum during a discrete trial session. When SDs are presented rapidly, it can create an engaging and dynamic learning environment that keeps the learner focused and active in responding. Quick delivery can encourage frequent engagement from the learner, making the session feel more productive and fluid. This approach also minimizes downtime and keeps the learner attentive, which is essential for reinforcing desired behaviors and ensuring effective skill acquisition.

On the other hand, delivering the SD slowly may hinder the pace of the session and could lead to decreased engagement. Providing a lot of time between trials can disrupt momentum, making it harder for the learner to maintain focus and transition smoothly from one task to another. Waiting to reinforce at the end of the session could also lead to missed opportunities for immediate reinforcement, which is crucial for strengthening desired behaviors throughout the session. Thus, quickly delivering the discriminative stimuli is the most effective strategy for maintaining momentum in discrete trials.
