By Matt Harrington, BCBA · Behaviorist Book Club · Clinical decision guide
One of the most consequential decisions a behavior analyst makes is not just what intervention to use, but how to approach the clinical question in the first place. For presession attention affects the acquisition of tacts and intraverbals, the difference between an evidence-based, individualized approach and a traditional, protocol-driven one can significantly impact outcomes.
This guide lays out the key factors side by side to support your clinical decision-making.
| 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.
