Generalization testing presents the problem of order effects, that is, the order in which different stimuli are presented during the generalization test may affect the subject’s response to them. For example, a stimulus presented soon after extinction has begun may be responded to differently than if that same stimulus were presented later during extinction. To solve this problem, the Sniffy program
a. presents the generalization stimuli during reinforcement rather than during extinction.
b. presents each generalization stimulus as though it were the first one to be presented after extinction began.
c. alternates periods of extinction with reinforcement during generalization testing.
d. gradually introduces extinction be presenting the reinforcer less and less often until reinforcement is replaced by extinction.
b. presents each generalization stimulus as though it were the first one to be presented after extinction began.
Answer feedback: The Sniffy program solves the problem of order effects during extinction by restarting the same file for each stimulus presentation during generalization testing. In this way, each stimulus is treated as the “first” to be presented during testing, that is, each stimulus that is presented occurs in the same order—namely, first.
