The 8th Perceptual Frontier Seminar: Symposium on Vection
Date and time: 6 August 2013, 17:00-19:00
Talk 1: Introduction to vection
Coherent motion over a large area of the visual field induces an observer’s self-motion perception, i.e. vection. I will present a basic introduction to vection research, providing a brief review of previous vection investigations. The talk will focus on their measuring methods and stimulus conditions.
Talk 2: Perceptual mechanism underlying jitter/oscillation effect in visually induced self-motion perception (vection)
It has been widely known that optic flow pattern which contains additional accelerating components (e.g. simulated viewpoint jitter or oscillation) can induce stronger forward vection than pure radial expansion. The jitter/oscillation effect has attracted vection researcher’s attention, because it cannot be consistently understood using traditional assumption that vection would be strengthened when visual and vestibular information concerning self-motion are in concordance with each other. In my talk, our recent experiments concerning the effects of additional jitter/oscillation on vection are reviewed in order to propose tentative hypothesis that can potentially accounts for the jitter/oscillation effects.
Talk 3: Influences of spatial layout on the perception of self-motion
Compelling experiences of self-motion, known as vection, can be produced in a stationary observer by visual stimulation alone. Normally this visual stimulation takes place in the context of the 3D layout of the environment and the omnipresent force of gravity. In this talk I will discuss our experiments investigating the role of spatial orientation and the perception of layout in the production of vection.
We will get together for dinner after the seminar. If you would like to join us for dinner, please let us know by sending an email to Dr. SENO (seno[at]design.kyushu-u.ac.jp) before August 3.
The 9th Perceptual Frontier Seminar: Cross-Cultural Studies of Auditory Perception
Date and time: 13 August 2013, 16:00-18:00
Presenters: Cong JIANG (Capital Normal University, Beijing, China), Tsuyoshi KURODA (Graduate School of Medical Sciences, Kyushu University), and Emi HASUO (Graduate School of Medical Sciences, Kyushu University)
Three young researchers, who have had chances to investigate influences of different cultures on auditory perception, will present their findings and new questions. Cong Jiang will talk about tonality perception in music. Tsuyoshi Kuroda will report a study on the perception of rhythm patterns extracted from different languages. Emi Hasuo will present a new question on a potential cultural difference in time perception.
