Stimulus Equivalence Learning in Acquired Brain Injury.
The Principle of Stimulus Equivalence Learning and Its Neuropsychological Correlates in Adults With Acquired Brain Injury (ABI).
Source: ClinicalTrials.gov · Last updated 22 May 2026
Brief summary (registry, in English)
Stimulus Equivalence Learning (SEL) is a form of learning in which stimuli (such as words, pictures, or sounds) become linked to one another in memory, even though this specific connection has not been directly taught. In a typical SEL task, two relations are taught explicitly (A→B and A→C), and the untrained relation (B→C) is then tested. This indirect relation is not intentionally or consciously learned and is considered a form of implicit learning. The principle of stimulus equivalence learning is still rarely applied in cognitive rehabilitation after acquired brain injury (ABI), with the exception of a few small (N=1) treatment studies that have shown positive effects. However, it remains unclear to what extent ABI may affect the ability to acquire stimulus equivalence.
