Basic and applied research on choice responding.

Zigman et al. (1997) wrote a story-style review. They pulled together lab work on how we pick one option over another.

The paper says four levers control our picks: how hard the task is, how often we get the payoff, how soon it comes, and how good it feels.

The review found the same four levers work in clinics, classrooms, and homes. If you tweak them, you can shift people toward better choices.

No numbers were given; the paper is a map, not a scoreboard.

Hall et al. (2005) extends these ideas to adults and kids with severe disabilities. Giving real choices cut problem behavior and lifted adaptive acts.

Lord et al. (1997) and Mueller et al. (2000) seem to contradict the map. Both ran trials where choice between good items added zero extra work. The key gap: their items were already top-preferred, so choice had no room to help. The map still holds; the lever just wasn’t needed.

Rung et al. (2019) stretch the frame into addiction work. They show delay discounting can be bent with the same levers, giving hope for impulsive clients.

You already control rate, delay, and quality in every program. Use brief probe sessions to see which lever is weakest, then twist it first. If the reinforcer is already loved, skip the extra choice step and save time.
