| 研究開始時の研究の概要 |
The ability to perceive and manipulate numbers supports our actions in various daily tasks. Elucidating factors influencing numerical cognition is important both theoretically and practically. This research aims to reveal attentional factors affecting counting and numerosity estimation performance.
|
| 研究実績の概要 |
Experiments were conducted to investigate how object color influences numerosity estimation. Results revealed an increase in estimated values with eight colors, suggesting a tendency to perceive larger quantities with more colors present. Notably, there was no difference between the 4-color and 1-color conditions, indicating a bias emerging with over four colors. This may relate to the capacity limit of visual attention, which is typically around four items. In my experiments, it is plausible that four colors are distinctly perceived, thus not leading to a numerical bias. However, with eight colors, attention capacity is overwhelmed, resulting in an impression of a large variety of colors. Consequently, observers perceived 8-color displays as more numerous compared to 1-color displays.

理由
Progress has been made in understanding how object color impact numerosity estimation. Specifically, I identified a numerical bias in perceiving displays with multiple colors as more numerous compared to displays with a single color. Furthermore, I also discovered a boundary for this numerical bias: it appears that this bias emerges with more than four colors. This aligns with the limit of visual attention capacity, which is typically around four items. These findings shed new lights on the role of visual features in numerical perception.

| 今後の研究の推進方策 |
The experiments for the current research project have concluded, and the data analysis has unveiled theoretically significant findings. As I look forward to the upcoming academic year, my primary focus will be on drafting academic papers and disseminating my research outcomes in esteemed scholarly journals. Furthermore, I am dedicated to showcasing my work at prominent academic conferences, both domestically and internationally. Participating in and presenting my research at these conferences will be instrumental in elevating the caliber of my papers and shaping the trajectory of my future research pursuits. Consequently, I am committed to actively participating in academic conferences throughout the coming academic year.
