This comparison draws in part from “Presession Attention Affects the Acquisition of Tacts and Intraverbals” (CEUniverse), and extends it with peer-reviewed research from our library of 27,900+ ABA research articles. The decision framework, BACB ethics code references, and cross-links below are synthesized by Behaviorist Book Club.
View the original presentation →When verbal behavior acquisition is slower than expected, BCBAs typically focus their adjustment efforts within the session — modifying prompt hierarchies, adjusting reinforcement schedules, or switching reinforcer types. The presession attention research introduces a different level of analysis: the antecedent conditions that precede the session itself. Comparing these two approaches helps clarify when each is most applicable and how they can be used together.
Within-session adjustments address the instructional mechanics: how prompts are delivered, how consequences are timed, how many trials are run, and whether the reinforcer in use is still effective. These are direct levers on the learning process and should always be the first line of inquiry when acquisition stalls.
Presession attention manipulation operates at a different level — it primes the motivational context before instruction begins. Rather than adjusting what happens during a trial, it adjusts the value of the reinforcer before the session starts. Both approaches target acquisition efficiency, but they address different parts of the behavioral chain. Understanding when to prioritize each — and when to use both — is a mark of clinical sophistication.
| Factor | Evidence-Based Approach | Traditional Approach |
|---|---|---|
| Target variable | Presession attention manipulation targets the reinforcing value of social attention before the session begins | Within-session reinforcement adjustments target the delivery, timing, and type of reinforcement during trials |
| Mechanism of action | Operates through motivating operations — altering the establishing or abolishing operation for attention as a reinforcer | Operates through reinforcement schedule adjustments — changing the density, immediacy, or quality of consequence delivery |
| Data requirements | Requires tracking presession conditions across sessions and correlating with within-session acquisition rates | Requires within-session trial-by-trial data on correct responding and reinforcer delivery patterns |
| Implementation complexity | Requires caregiver coordination, waiting area protocols, and presession assessment procedures | Requires RBT training on modified reinforcement procedures and BCBA oversight of session mechanics |
| Best use case | Most useful when between-session variability is high and within-session instructional variables have been ruled out | Most useful when acquisition is consistently slow or when reinforcer potency is visibly low during sessions |
| Generalization impact | Presession conditions are difficult to control in natural environments; gains may not generalize if motivation varies widely | Adjusting reinforcement schedules toward natural, intermittent schedules directly supports generalization to natural environments |

Use this framework when approaching presession attention affects the acquisition of tacts and intraverbals in your practice:
Does the data support a need for intervention? Is there a meaningful impact on the individual's quality of life, safety, or access to reinforcement?
YES → Proceed to assessment NO → Document reasoning, monitor
A functional assessment should guide intervention selection. Avoid defaulting to standard protocols without individual analysis. Consider environmental variables, setting events, and private events.
YES → Select evidence-based approach matched to function NO → Complete assessment first
Goals should be co-developed. Assent and informed consent are ethical requirements. The individual's preferences and values matter in selecting both goals and methods.
YES → Proceed with collaborative plan NO → Engage in shared decision-making
This course covers the clinical and ethical dimensions in detail with structured learning objectives and CEU credit.
