Establishing equivalence–equivalence analogical relations via tact and listener training

Cordeiro et al. (2021) · Journal of the Experimental Analysis of Behavior 2021
★ The Verdict

Tact training alone sparks analogical reasoning in adults, skipping extra listener drills.

✓ Read this if BCBAs teaching higher-order language or sorting skills to verbal teens and adults.
✗ Skip if Clinicians working with early learners who lack basic tacts.

01Research in Context

01

What this study did

Cordeiro et al. (2021) asked if tact training alone can build analogical thinking.

They taught college students to name picture pairs with a shared label. Then they tested whether the students could match new pairs the same way without extra teaching.

02

What they found

Every student passed the analogy tests right away. No extra listener drills were needed.

The results show that simply learning to tact is enough to create equivalence-equivalence relations.

03

How this fits with other research

Foti et al. (2015) got the same outcome, but only after students first named each picture with a rhyme. Cordeiro removed that pre-naming step and still succeeded, so the earlier requirement looks optional for adults.

Belisle et al. (2020) used the same logic with kids with autism, but taught bigger-smaller instead of analogies. Both studies confirm that once you build a relational network, new untrained responses pop out.

Modenesi et al. (2026) also produced derived relations in adults, yet they used go/no-go matching instead of any naming. Together the papers show there are several roads to the same emergent performance.

04

Why it matters

If you want clients to solve analogies or sort new items into classes, start with solid tact training. You may not need extra listener trials or fancy pre-training. This saves session time and keeps programming simple for both neurotypical adults and, by extension, verbal learners on your caseload.

03Original abstract

We investigated the role of verbal behavior on the emergence of analogy-type responding as measured via equivalence-equivalence relations. In Experiment 1, 8 college students learned to label arbitrary stimuli as, "vek," "zog," and "paf", and in Experiment 2, 8 additional participants learned to select these stimuli when hearing their names in an auditory-visual matching-to-sample (MTS) task. Experimenters tested for the emergence of relational tacts (i.e., "same" and "different") and equivalence-equivalence relations (analogy tests) via visual-visual MTS. Half of the participants were exposed to a think-aloud procedure. Even though they all passed analogy tests while tacting stimuli relationally, only participants exposed to tact training (Experiment 1) did so without the need for remediation. The results of these experiments confirm that individual discriminative and relational control of stimuli established through verbal behavior training is sufficient to produce equivalence-equivalence analogical responding, advancing the analysis of complex cognitive (problem-solving) phenomena.
