How Is Simultaneous Prompting Different From Time Delay?

Compare the trial diagrams

For each procedure, write the cue, preprompt interval, prompt, response window, consequence, and next trial. A zero-second phase inside a time-delay program does not make the full program identical to simultaneous prompting.

Locate independent opportunities

With simultaneous prompting, the formal independent test occurs during separate probes. With delayed prompting, a learner can respond before the prompt during teaching trials once a delay is active. Reports should identify the procedure and phase.

Use comparative evidence carefully

A comparison study examined simultaneous prompting and constant time delay with autistic participants. Its assigned skills, procedures, and results do not establish a universal winner. The BACB outline covers prompt fading, time delay, stimulus control, and evaluation.

Preserve person-specific safeguards

The Ethics Code addresses assessment, involvement, assent when applicable, risk, and data-based change. ASHA supports continual AAC access. Wait time should reflect motor and processing access rather than a race against the prompt.

A practical example

One plan uses an immediate gesture on all teaching trials and no prompt on next-day probes. Another starts with immediate gestures, then waits three seconds during teaching. The team records independent responses by the rule for each plan and avoids pooling the percentages.

Questions families can use

Is there a delay during teaching? Where can an independent response occur? Is there a separate probe? What happens after an error? Does the delay allow the person's actual response time?
