The modification of short-term memory through instructions to forget
- 323 Downloads
This study was designed to investigate whether Ss could reduce the proactive interference of a first verbal item (CCCC) if they were signalled just prior to the presentation of a second item that they could forget the first item. Recall of the second of two CCCC items inserted in a series of digits was better when Ss were told to “drop” the first item than when there was no such instruction, but it was not as good as recall when only one item was presented.
