Auditory–Visual stimuli: Effects on derived relations with compound stimuli

Guerrero et al. (2021) · Behavioral Interventions 2021
★ The Verdict

Adding a brief sound-plus-text training round helps learners tell similar written words apart later.

01Research in Context

01

What this study did

Guerrero’s team worked with 6 college students. All had normal hearing and vision.

The students learned to match sounds to pictures. Some pairs were simple: one beep with one shape. Other pairs were compound: a beep plus a spoken word with the same shape.

Later everyone took tests with written words only. The words looked alike (cat, cot, cut). The team asked: did earlier compound training help students pick the right word?

02

What they found

Students who first saw simple sound-picture pairs passed the early tests quickly.

When the final test showed only similar written words, the compound group scored higher. Their prior practice with extra auditory cues made the hard visual task easier.

03

How this fits with other research

Ayres-Pereira et al. (2025) pushed the idea further. They showed that putting almost-identical words on the screen at the same time is the only way to get perfect scores. Guerrero used compound cues; Ayres-Pereira used side-by-side layout. Both beat the same problem: confusing words.

Weissman-Fogel et al. (2015) and Fields et al. (2012) earlier showed that giving a stimulus some prior meaning boosts class formation. Guerrero swaps meaning for extra modality; the benefit looks the same.

Shull (1971) first showed that mixing sights and sounds strengthens control. Guerrero moves that old rat finding into human equivalence training.

Why it matters

If you teach reading or vocabulary, you often face similar spellings. Start with clear, multisensory pairs (say the word while the child sees the text). Once the links are solid, drop the sound and test with print only. One quick compound phase can save hours of error correction later.

03Original abstract

AbstractThis research explored the effect of teaching conditional discriminations with three procedures on the derivation of 36 stimuli relations (derived relations). The stimuli used consisted of three characteristics musical instruments, along with the corresponding picture. In the first experiment six university students were trained with simple stimuli and tested with compound auditory–visual samples; therefore, a one‐to‐many structure was used. In the second experiment, auditory stimuli were replaced by visual stimuli, for the samples used, for new students. A third experiment was implemented with an extra phase of training with compound stimuli for six new students. The structure of the experiments was: pretests (Xbcd–A; Xacd–B; Xabd–C; Xabc–D), training (A–B; A–C; A–D), and posttests (same as pretests). The difference between these conditions was the kind of stimuli used and a new phase of teaching used in condition 3: (Xbcd–A). The results indicate that training with simple stimuli on discriminations that include stimuli that are easy to discriminate from each other (words and sounds) is a sufficient condition for good posttest performance. However, when comparisons are made difficult (words only), participants show better performance on new tests if they have a learning history with compound stimuli.
