Differential outcomes training improves face recognition memory in children and in adults with Down syndrome.
Linking each correct face to its own small prize sharply boosts face memory in clients with Down syndrome.
01Research in Context
What this study did
Sparaci et al. (2014) tested a simple twist on reinforcement. Each correct face got its own special reward. One face meant a sticker, another meant a piece of cereal.
They ran the game with kids and adults with Down syndrome. They also tested neurotypical children. Everyone tried the same face-memory task under two rules: unique reward or same reward every time.
What they found
Face memory shot up when each face had its own prize. Both the Down-syndrome group and the typical kids scored better with the unique-reward setup.
The gains were large enough to matter in everyday teaching. Memory improved right away during the session.
How this fits with other research
De Meyer et al. (2021) saw the same boost in kids with ADHD. Unique rewards erased their learning gaps and brought scores up to typical levels. The pattern repeats: special reinforcer for each correct choice equals better learning.
Neuringer et al. (2007) looks like the opposite story. They found children with Down syndrome were worse at reading facial emotions. Laura’s group shows the same population can improve on face tasks when the reward structure is tweaked. The tasks differ—emotion recognition versus memory—so the papers don’t truly clash.
Y-Ting et al. (2017) used computer visual training and also improved perception in Down syndrome. Laura’s study adds that a low-tech reward change, not fancy software, can deliver a quick memory win.
Why it matters
If you teach matching, safety signs, or social skills that rely on remembering faces, swap in unique rewards. Give one picture a high-five, another a skittle. The small change can unlock better performance in clients with Down syndrome without extra equipment or hours.

03Original abstract
Previous studies have demonstrated that the differential outcomes procedure (DOP), which involves paring a unique reward with a specific stimulus, enhances discriminative learning and memory performance in several populations. The present study aimed to further investigate whether this procedure would improve face recognition memory in 5- and 7-year-old children (Experiment 1) and adults with Down syndrome (Experiment 2). In a delayed matching-to-sample task, participants had to select the previously shown face (sample stimulus) among six alternatives faces (comparison stimuli) in four different delays (1, 5, 10, or 15s). Participants were tested in two conditions: differential, where each sample stimulus was paired with a specific outcome; and non-differential outcomes, where reinforcers were administered randomly. The results showed a significantly better face recognition in the differential outcomes condition relative to the non-differential in both experiments. Implications for memory training programs and future research are discussed.
