The concordance between performance and judgements of the causal effectiven
ess of an instrumental action suggests that such actions are media ted by c
ausal knowledge. Although causal learning exhibits many associative phenome
na-blocking, inhibitory or preventative learning, and super-learning-judgem
ents of the causal status of a cue can be changed retrospectively as a resu
lt of learning episodes that do not directly involve the cue. In order to e
xplain retrospective revaluation, a modified associative theory is describe
d in which the learning processes for retrieved cue representations are the
opposite to those for presented cues, and this theory is evaluated by stud
ies of the role of within-compound associations in retrospective revaluatio
n and blocking. However, this modified theory only applies when the within-
compound association represents a contiguous rather than a causal cue relat
ionship.
