Stimulus Equivalence Learning in Acquired Brain Injury.

Condition(s) studied

Study summary

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.

Eligibility

Primary outcome measure(s)

• Modified Rutgers Equivalence Learning Task (mRAET) — Day 1
  The original RAET is an experimental paradigm in which faces have to be paired with colored fish. For the current study, this task has been adapted into a more ecologically valid version focused on medication intake, in which relationships are learned between the shape of a pill, the function of the pill, the time of intake, and the (fictional) brand name.
