Control of memory retrieval alters memory-based eye movements

Past work has shown that eye movements are affected by long-term memory across different tasks and instructional manipulations. In the current study, we tested whether these memory-based eye movements persist when memory retrieval is under intentional control. Participants encoded multiple scenes with six objects (three faces; three tools). Next, they completed a memory regulation and visual search task, while undergoing eye tracking. Here, scene cues were presented and participants either retrieved the encoded associate, suppressed it, or substituted it with a specific object from the other encoded category. Following a delay, a search display consisting of six dots intermixed with the six encoded objects was presented. Participants' task was to fixate one remaining dot after five had disappeared. Incidental viewing of the objects was of interest. Results revealed that performance in a final recognition phase was impaired for suppressed pairs, but only when the associate was a tool. During the search task, incidental associate viewing was lower when participants attempted to control retrieval, whereas one object from the nonassociate category was most viewed in the substitute condition. Additionally, viewing patterns in the search phase were related to final recognition performance, but the direction of this association differed between conditions. Overall, these results suggest that eye movements are attracted to information retrieved from long-term memory and held active (the associate in the retrieve condition, or an object from the other category in the substitute condition). Furthermore, the level of viewing may index the strength of the representation of retrieved information. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
