Capacity limits in list item recognition: Evidence from proactive interference

Capacity limits in short‐term recall were investigated using proactive interference (PI) from previous lists in a speeded‐recognition task. PI was taken to indicate that the target list length surpassed working memory capacity. Unlike previous studies, words were presented either concurrently or sequentially and a new method was introduced to increase the amount of PI. On average, participants retrieved about four items without PI. We suggest an activation‐based account of capacity limits.
