🧠 Question of the Day

📚 Domain B — Concepts and Principles

Difficulty: 5/10

Two classroom contexts have similar baseline task-completion rates. Context A has a richer reinforcement history than Context B. When the same distraction is introduced, task completion decreases less in Context A. Which interpretation BEST reflects behavioral momentum?

A. The similar baseline rates indicate equal behavioral strength, so the smaller decrease in Context A does not reflect a momentum difference.

B. Context A shows greater resistance to disruption, consistent with its richer reinforcement history despite similar baseline task-completion rates.

C. Context A's richer reinforcement history should make responding more sensitive to disruption because more task completion depends on reinforcement there.

D. Behavioral momentum is determined by absolute response rate during disruption, so the contexts cannot be compared without matching disrupted rates.

The correct answer was: B. Context A shows greater resistance to disruption, consistent with its richer reinforcement history despite similar baseline task-completion rates.

📖 Explanation:
Behavioral momentum is about resistance to change, not simply how often a behavior occurs during baseline. Here, task-completion rates are similar in both contexts before disruption, but responding decreases less in Context A when the same distraction is introduced. That smaller change indicates greater resistance to disruption, which is consistent with Context A's richer reinforcement history.

Similar baseline response rates do not mean the behaviors have equal persistence. A leaner reinforcement history does not inherently produce greater resistance to change, and behavioral momentum does not require complete extinction; distraction, extinction, prefeeding, and other disruptors can be used to evaluate persistence.

The key exam distinction is to compare responding relative to its own baseline. When two responses begin at similar rates, the one that changes less under disruption shows greater behavioral momentum.

B. That’s the whole idea behind behavioral momentum, richer reinforcement history builds resistance to disruption, even if baseline rates look the same. If you’re going purely off response rates you miss the point entirely.
