| Outline of Annual Research Achievements |
The results of the FY 2021 experiments showed that counting performance was inhibited when color-based segmentation was not possible. Specifically, when the objects in the display were randomly colored, participants had more difficulty counting them compared to displays where color-based segmentation was possible.
In FY 2022, a follow-up experiment was conducted to investigate whether attentional cues can improve counting performance in situations where object color cannot be used to segment the display. This experiment used displays of objects that were randomly colored, making it difficult to segment the objects based on their color. Attentional cues were provided to direct the participant's attention to objects having the cued color. The results showed that attentional cues can improve counting performance even in situations where color-based segmentation is not possible. This suggests that attentional cues can serve as an effective alternative to color-based segmentation in improving counting performance.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
Progress has been made in understanding the effects of object color and attentional cues on counting performance, and how these factors interact in different situations.
Specifically, investigating the effects of attentional cues on counting performance in situations where color-based segmentation is not possible is an important step forward in the project. It suggests that the methods used in my previous experiments can be adapted to new situations.

| Strategy for Future Research Activity |
Investigating the effects of object color and attentional cues on numerosity estimation would provide further insights into the complex processes underlying numerical processing, and could have important implications for understanding how visual features influence cognitive processes more broadly.
In FY2023, experiments will be conducted to determine whether object color affects estimation precision and whether attentional cues can be used to facilitate estimation performance.
Data collection for the experiment investigating the effect of object color on numerosity estimation has already begun. Data will be analyzed as soon as possible to draw meaningful conclusions. Preparation for the experiment investigating the effects of attentional cues is in progress, and pilot data collection will start soon.

| Causes of Carryover |
Follow-up experiments will be conducted in FY 2023 to verify the results of previous experiments and further exploring the topic of object color and attentional cues on numerical cognition.
Moreover, I am planning to present the findings at conferences both domestic and abroad to disseminate the research to a wider audience.
The incurring amount will be used to cover both participant payments and conference expenses.
