| 研究開始時の研究の概要 |
Working memory is one of the most important of cognitive psychological functions. Investigating it is typically a resource intensive process involving hundreds of trials of recalling static images. This project will develop a new experimental paradigm to measure visual working memory based on recalling dynamic sequences. By introducing movement into memory, the task remains simple and intuitive, but aggregating the memory response across time makes it eminently more efficient, powerful and representative of the true memory state.

| 研究実績の概要 |
This project set out to create an efficient method to measure dynamic working memory. This was successfully achieved by presenting moving stimuli on a touchscreen monitor, before asking participants to reproduce the movement path that the stimulus took. A custom algorithm was developed to quantify the degree of similarity between the participant's response with the original stimulus movement, with a higher degree of similarity indicating larger working memory performance.
As theorized in the original plan, the final paradigm is still able to investigate the effect of memory load and retention interval on working memory, as with standard working memory paradigms. However, this new paradigm is able to visualize working memory variance both across trials, and within a single trial. This new method was found to be powerful, requiring only small sample sizes and few trials to find differences in experimental conditions. The measurement was also found to be reliable, with a higher degree of agreement amongst multiple measurements (i.e., Cronbach's alpha of approx 0.9). Experiments were also performed to ensure that the new paradigm was indeed measuring working memory, rather than perceptual ability or attentional resources.
Developmental milestones were presented at the Australasian Experimental Psychology conference, the Asia Pacific Conference for Vision and the Vision Science Sciences Society. The finalized paradigm was published in the international journal, Memory & Cognition in 2025.
