Note. Lag-2=lag-2 repetitions, PI=positional interference, SI=self-inhibition, IC=integrative chaining. For Lag-2, PI, and IC the table shows positions where these accounts predict costs. For SI the table shows positions where self-inhibition would counteract interference from the prime competitor.
