This study delves into the rule of thirds, a pivotal principle in visual arts and design, assessing its application in enhancing memory recall and accuracy. We investigated if visual stimuli alignment with rule of thirds (ROT) points within a visual field could optimize memory performance, a question of significant interest in the field of visual perception. Participants completed an odd-one-out visual search task featuring a 5x5 matrix of lines, each with a distinctively oriented target line. The matrix incorporated 4 ROT lines at key intersection points, 4 Non-ROT lines centrally placed at similar distances as ROT lines, 16 Far lines at the margins, and 1 central line, with slight jitter added. The focus was on comparing the accuracy of memory recall for target orientations across these spatial positions. The results demonstrated that positioning lines at ROT points significantly enhanced the accuracy of reported orientations compared to other screen locations, specifically non-ROT, indicating an advantage in spatial memory. Reaction times (RTs) were similar between ROT and Non-ROT points, suggesting the improvement in memory accuracy was not due to faster processing. However, both ROT and Non-ROT locations yielded faster RTs than Far locations, indicating central positioning's role in expedited response. Our research underscores the vital impact of spatial positioning on visual memory, particularly emphasizing the rule of thirds as an influential factor in visual perception and human-computer interaction. By strategically aligning items with the rule of thirds, we observed a notable enhancement in memory accuracy. This finding has considerable implications for the design of user interfaces and educational materials, moving beyond mere aesthetics to practical applications in spatial memory. Such insights pave the way for further HCI research, aimed at refining visual layouts to boost user engagement and learning efficiency.
