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 from pigeons to behavioral economics: an interview with leonard green, 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 |
|---|---|---|
| Core mechanism | Temporal discounting: Reinforcer value decreases as delay to delivery increases; immediate rewards are systematically preferred over larger delayed alternatives | Probability discounting: Reinforcer value decreases as outcome certainty decreases; certain rewards are preferred over probabilistic alternatives of equal magnitude |
| Clinical populations most affected | Temporal discounting: ADHD, substance use disorders, gambling presentations, some ASD presentations — all associated with steeper-than-average delay sensitivity | Probability discounting: Anxiety presentations, rigid or inflexible behavioral repertoires, clients with histories of unpredictable reinforcement, some ASD presentations with intolerance of uncertainty |
| Behavioral manifestation | Temporal discounting: Persistent preference for small immediate rewards; difficulty sustaining behavior toward delayed goals; poor tolerance for token economy delays | Probability discounting: Avoidance of variable reinforcement contexts; resistance to naturalistic teaching with unpredictable reinforcement; preference for highly predictable routines and outcomes |
| Measurement approach | Temporal discounting: Delay discounting tasks presenting choices between smaller-sooner and larger-later options across a range of delay values; generates hyperbolic discount rate parameter k | Probability discounting: Probability discounting tasks presenting choices between certain and probabilistic reinforcers across a range of probability values; generates odds-against discounting function |
| Primary intervention implication | Temporal discounting: Immediate reinforcement delivery in early program phases; systematic delay fading to build delay tolerance; token economies with progressive delay increases | Probability discounting: Gradual introduction of variability to reinforcement schedules; exposure-based approaches to uncertainty; building flexible reinforcement repertoires |
| Schedule design consideration | Temporal discounting: Fixed-ratio and fixed-interval schedules with short delays are more effective initially; variable schedules introduced gradually as delay tolerance increases | Probability discounting: Highly predictable schedules initially; variable ratio and naturalistic schedules introduced in a planned sequence as tolerance for uncertainty develops |

Use this framework when approaching from pigeons to behavioral economics: an interview with leonard green 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.
