The contribution of contextual information to recognition judgments has a c
omplex history, both theoretically and empirically. Three main theories of
context effects in recognition make contrasting predictions about the role
of context as the memory strength of a focal item increases: The outshining
hypothesis predicts that context effects will diminish as the memory stren
gth of an item increases, additive global matching models of memory predict
that the magnitude of context effects will be unaffected by the memory str
ength of the item, and multiplicative global matching models predict that t
he magnitude of the context effect will increase with the strength of the i
tem. We reviewed the evidence for each of these theories and conducted 3 ex
periments consistent with the additive global matching models.
