This experiment looked at the transition between retrieval and inferences with time. In her task subjects read stories and then had to judge either whether sentences were explicitly presented as part of the story (in the recognition condition) or whether they were plausible (in the plausibility condition). Reder's stories consisted of complex, free-form sentences. To simplify the syntactic processing, we presented ACT-R stories consisting of subject-verb-object sentences like
Bob entered the-restaurant
Bob ordered the-meal
The-waiter delivered the-meal
Bob ate the-meal
Then ACT-R was tested either with sentences it had studied like
Bob entered the-restaurant
or sentences which were consistent with the script like
Bob left the-restaurant
or in the plausibility condition with sentences that did not fit the script like:
Bob delivered the meal
Subjects were either tested immediately after reading the story (which Reder interpreted as a 120 second delay), after 20 minutes, or after 2 days.
