Item Competition and forgetting during context-based episodic memory retrieval(2016-11) Jeanneret, Stephanie; Hollenbeck, Mark; Dutcher, Anthony; Lewis-Peacock, JarrodItem Effects of Mood on Directed Forgetting(2023) Zheng, Sabrina; Lewis-Peacock, Jarrod A.Working memory is the ability to retain and manipulate a limited amount of information. It’s limited in the amount of information it can hold simultaneously, therefore it would be beneficial to effectively remove information intentionally. The item method directed forgetting task is one way to investigate how information is removed from memory. Studies have continually shown that memory for items that are associated with a remember cue are remembered better than items associated with a forget cue, known as the directed forgetting effect. Mood states may be one factor that impacts the directed forgetting effect, but these effects have not been extensively studied. Negative mood states tend to enhance detailed processing leading to better memory for item level details, whereas positive mood states promote global processing leading to more categorical memory. Prior literature has found mixed results regarding the impact of mood on an item-method directed forgetting task; some finding that a negative mood reduces forgetting while others finding that negative mood has no effect on forgetting when compared to a positive mood condition. These previous studies did not specify methods of forgetting which may explain the inconsistent results. This study investigated the effects of sad and happy moods on the directed forgetting operational cues: maintain, clear, and suppress. Results suggested that mood was successfully manipulated only in the positive mood group which could explain the insignificant differences in memory between the two mood groups. Interestingly, memory was worse for clear cued memory items over maintain items in the positive mood group, suggesting that clear was a more effective forget cue than suppress. Future studies will investigate alternative methods to manipulate mood more effectively to fully explore our research question. These effects could help us better understand and treat patients suffering mental health conditions involving intrusive thoughts.
