Working memory (short WM) is the system responsible for holding mental representations temporarily available for later use in thought or action (Oberauer et al., 2018). Because WM has a severely limited capacity, WM content needs to be constantly updated to focus on current, relevant information. Supporting seamless updating, WM is remarkably efficient in getting rid of outdated information from WM as evident in robust directed forgetting effects in WM: In a recent study from our lab (Dames & Oberauer, in press), participants were instructed to remember a list of up to six sequentially presented words. After the offset of each word, a memory cue indicated whether this word should be remembered or could be forgotten. On a small subset of trials, we probed one of the to-be-forgotten (TBF) words – on all other trials, only to-be-remembered (TBR) words were tested. We found that memory performance for TBF words was much poorer than for TBR words (directed-forgetting effect). Forgetting in WM was accompanied by facilitation effects for the remaining, still relevant TBR words in WM. Together, consistently poor recognition performance for TBF words and facilitation of TBR words demonstrated that intent had a strong impact on WM maintenance. Using the same task but additionally manipulating the time between the offset of the memory cue and the onset of the next word (cue-stimulus-interval, CSI), in a previous experiment, we found that memory performance for both TBR and TBF words increased with increasing CSIs. The present study is an extension of this work where we will test the long-term effects of directed forgetting in WM by adding a LTM test at the end of the WM task. From previous studies, we already know that directed forgetting in WM results in better LTM for TBR than TBF words (long-term directed forgetting). In this experiment, we will test whether the CSI impacts this long-term directed forgetting effect: Participants will be instructed to remember up to eight words presented sequentially across a circular arrangement of frames. Immediately after presentation of each memory set, we will assess participants’ item and binding memory in form of a two-step test: First, we will test participants’ item memory by presenting one randomly selected old word and a completely new word in the center of the screen. Using their computer mouse, participants’ first task will be to select the word that was previously presented in that trial. Next, to measure participants’ binding memory, we will ask participants to select the frame the old word was previously presented in by clicking on it. In the immediate test, only TBR words will be tested. At the end of the experiment, we will use the same test procedure to assess participants’ LTM of the words that were not tested in the WM phase. This test will also include test of TBF words.
