Reaction times of younger and older men: effects of compound samples and a prechoice signal on delayed matching-to-sample performances.

Researchers tested two ways to speed up delayed matching-to-sample. They worked with younger and older adult men who had no disabilities.

Each trial showed a complex sample shape. After a short delay, two choice shapes appeared. The men had to pick the one that matched the sample.

Adding a tiny beep right before the choices appeared cut reaction time. Giving only a brief window to answer also made both age groups respond faster.

The tricks worked even when the sample held many parts. Older men kept up with younger men when these supports were in place.

Dube et al. (1998) later dropped the usual one-trial warm-up for learners with severe ID. Their tweak let most participants master identity matching after earlier failures. Jason et al. (1985) show the same task can be sped up in neurotypical adults just by adding a signal and a deadline.

POLIDORNEVIN et al. (1963) used timeouts to cut wrong choices in pigeons. They found very short or very long timeouts hurt learning. Jason et al. (1985) take the opposite path: they reward fast correct responses instead of punishing slow ones. Both studies aim to sharpen discrimination, but one adds cues while the other removes reinforcers.

Hamm et al. (1978) trained a child with Down syndrome on memory span. Daily varying lists lifted recall. Jason et al. (1985) show that small procedural tweaks—just a beep and a timer—can boost memory performance in older adults without extra training.

If you run matching tasks with clients, try a one-second tone before choices and set a 3-second response cap. These tiny changes cut latency and keep accuracy up, even when samples get complex. The setup works for both young and elderly learners, so you can use it across age groups without extra materials.
