Does Context Mitigate Memory Interference in Competitive Retrieval? ----- A Pupillometry Approach
(2023) PSYP01 20231Department of Psychology
- Abstract
- Memory competition often hinders the retrieval of a particular event. It has long been established that access to the encoding context facilitates later retrieval. Previous research suggested that context is encoded alongside with event memories like bookmarks and can be used to differentiate target memory from competitors. The current study used pupillometry to investigate if context mitigates memory interference in competitive memory retrieval. Participants (N = 35) were first presented with a series of word-pair associates in different context. Half of the word-pairs were competitive that had overlapping cues(AB/AC), with AB presented earlier than AC, while the other half being non-competitive that had non-overlapping cues(DE) . The...

- Memory competition often hinders the retrieval of a particular event. It has long been established that access to the encoding context facilitates later retrieval. Previous research suggested that context is encoded alongside with event memories like bookmarks and can be used to differentiate target memory from competitors. The current study used pupillometry to investigate if context mitigates memory interference in competitive memory retrieval. Participants (N = 35) were first presented with a series of word-pair associates in different context. Half of the word-pairs were competitive that had overlapping cues(AB/AC), with AB presented earlier than AC, while the other half being non-competitive that had non-overlapping cues(DE) . The word-pairs were later retrieved with or without the encoding contexts. The results suggested that memory performance of AC word-pairs suffered from a proactive interference and this interference was mitigated by the presence of context. Pupil response indicated that the proactive interference may already be form during encoding. Also, retrieval of the target word was found to impair the memory of the competing word, but this effect was not influenced by the access to context. The current study provided novel evidence for the role of context in competitive memory retrieval and showed that pupil response can track the cognitive effort directed towards resolving memory interference.
