The summer conference season has come to a close, and the fall semester is now underway. This September, several members completed their time in our lab: Li-san (Ph.D. course), Jiang-san (Master’s course), Zhu-san (graduate research student), and Horvathova-san (international exchange student). Congratulations to all of you, and thank you for your hard work! We wish you every success in your future endeavors. At the same time, we are delighted to welcome new members starting this semester: Shiyang Wang  (Ph.D. course), Sizhong Li  (Master’s course), and Megumi Kobayashi (research student). We look forward to working together and making great progress with our new team!

It’s been a while since the last post. In the meantime, we had several events, including the master’s thesis defenses by Jiang-san and Wang-san, and my invited talk and designated discussant sessions at the annual meeting of the Japanese Society of Ophthalmological Optics as well as the 89th Annual Convention of the Japanese Psychological Association. Starting September 10, our students will be presenting at a conference again: three of our second-year master’s students—Oda-kun, Kawahara-kun, and Miyoshi-kun—will give presentations at the Summer Meeting of the Vision Society of Japan in Morioka. In addition, Sato-sensei from Kanazawa University, with whom we are continuing a collaborative project, will also present at this meeting.

At the Annual Meeting of the Color Science Association of Japan, both Son-san and A/Prof Nagai received a variety of questions, making the presentations very meaningful. Next, our Ph.D. students, Son-san, Killian, and Hanada-kun will be presenting at the Asia-Pacific Conference on Vision (APCV2025), which will be held in Sydney, Australia. Son-san will give an oral presentation, Killian has been invited to give a symposium talk, and Hanada-kun will present a poster. We also plan to visit my colleagues' lab at the University of New South Wales during our trip.

• Son, M. & Nagai, T.: Comparison of color directions in simple reaction time following an abrupt decrease in background luminance.

• Duay, K.: HMD color calibration and a color constancy study in VR.

• Hanada, I. & Nagai, T.: The role of color distribution rarity in color preferences for abstract paintings: a machine learning analysis.

We welcomed Ms. Greta Horvathova, a PhD student from Imperial College London, as an international exchange student. She will be staying in our lab for three months, during which she will take part in psychophysical experiments related to color. Although her stay is short, we hope she will have meaningful interactions with our students. As this is her first visit to Japan, we hope she enjoys her time here to the fullest!
