Translations in Stimulus–Stimulus Pairing: Autoshaping of Learner Vocalizations

da Silva et al. (2020) · Perspectives on Behavior Science 2020
★ The Verdict

Run SSP like autoshaping: use very different sounds and tight timing to spark first words.

✓ Read this if BCBAs teaching early vocalizations to minimally verbal learners.
✗ Skip if Clinicians already getting strong echoics with standard SSP.

01Research in Context

01

What this study did

da Silva et al. (2020) wrote a theory paper. They asked: can we make stimulus-stimulus pairing (SSP) work better for teaching first words?

They pulled rules from animal autoshaping studies. They showed how to pick sounds, time trials, and keep gains.

02

What they found

The team says SSP is just autoshaping for voices. To get more words, make the adult sound very different from the toy sound.

Keep the gap between sounds short and steady. Fade extra cues so only the target sound gets the response.

03

How this fits with other research

Older work backs them up. Gillberg et al. (1983) proved pigeons peck faster when color and intensity differ, a direct map to the "big disparity" rule.

Neuringer (1973) and Yuwiler et al. (1992) showed shorter key lights give faster pecking. da Silva copies this to set tight inter-trial intervals in SSP.

Mulvaney et al. (1974) found monkeys acquired key-presses but lost them when food no longer followed. The new paper uses that warning to tell us guard SSP gains with strong pairings.

04

Why it matters

If you run SSP for early echoics, treat it like bird training. Pick sounds that stand out, keep trials brisk, and probe often to be sure the link sticks. These tweaks cost nothing but can save weeks of stuck progress.

03Original abstract

Stimulus–stimulus pairing (SSP) is a procedure used by behavior analysis practitioners that capitalizes on respondent conditioning processes to elicit vocalizations. These procedures usually are implemented only after other, more customary methods (e.g., standard echoic training via modeling) have been exhausted. Unfortunately, SSP itself has mixed research support, probably because certain as-yet-unidentified procedural variations are more effective than others. Even when SSP produces (or increases) vocalizations, its effects can be short-lived. Although specific features of SSP differ across published accounts, fundamental characteristics include presentation of a vocal stimulus proximal with presentation of a preferred item. In the present article, we draw parallels between SSP procedures and autoshaping, review factors shown to affect autoshaping, and interpret autoshaping research for suggested SSP tests and applications. We then call for extended use and reporting of SSP in behavior-analytic treatments. Finally, three bridges created by this article are identified: basic-applied, respondent–operant, and behavior analysis with other sciences.
