  • Refereed, Sage Open, SAGE Publications, Women Approach Cute Objects but Avoid Cute Adult Female Faces: Verification of Correlation between Body Sway and Cuteness Rating, Kana Kuraguchi; Kanon Fujimoto; Kosuke Taniguchi, Perceived cuteness motivates people to approach cute objects, but no evidence exists of unconscious approach behavior toward objects. Given the unconscious responses associated with cuteness perception, an unconscious drive to physically approach cute objects is likely to occur. However, approach behavior may or may not occur depending on whether or not the perceived cute object is an adult, a baby, or a non-human. In this study, we recruited 24 participants and conducted a correlation study between cuteness ratings and body sway to examine whether or not the approach response is dependent on perceived cuteness. Results showed that the approach or avoidance response to cute objects was observed only in women. For babies, the approach response occurred regardless of the degree of cuteness, but for adult female faces, the cuter the face, the more the avoidance response occurred. For non-human images, the cuter the image, the more the approach response occurred only in early period of observation time. These results suggest that cuteness perception controls physical distance differently depending on the target of evaluation., Apr. 2024, 14, 2, Scientific journal, 10.1177/21582440241255726

  • Frontiers in Virtual Reality, Frontiers Media SA, Comparing measurements of head motion and centre of pressure for body sway induced by optic flow on a head-mounted display, Hiroshi Ashida; Kanon Fujimoto, We compared two measures of visually induced body sway—head motion and centre of pressure (CoP)—that were simultaneously measured while observing optic flow on a head-mounted display (HMD). Head motion can be conveniently tracked with HMDs, but may have some features different from those of conventional CoP measurements, because of the complex joint structures of the human body. In this analysis, the responses were very similar (except for response gain), and we did not find any significant differences in time or frequency domains. Our results support the use of head motion as a potential predictor of variability in body sway, at least in studies of visually guided postural control., 14 Oct. 2022, 3, Scientific journal, 10.3389/frvir.2022.1026718

  • Refereed, Journal of Vision, Postural adjustment as a function of scene orientation, Kanon Fujimoto; Hiroshi Ashida, Visual orientation plays an important role in postural control, but the specific characteristics of postural response to orientation remain unknown. In this study, we investigated the relationship between postural response and the subjective visual vertical (SVV) as a function of scene orientation.We presented a virtual room including everyday objects through a head-mounted display and measured head tilt around the naso-occipital axis. The room orientation varied from 165° counterclockwise to 180° clockwise around the center of display in 15° increments. In a separate session, we also conducted a rod adjustment task to record the participant’s SVV in the tilted room.We applied a weighted vector sum model to head tilt and SVV error and obtained the weight of three visual cues to orientation: frame, horizon, and polarity.We found significant contributions for all visual cues to head tilt and SVV error. For SVV error, frame cues made the largest contribution, whereas polarity contribution made the smallest. For head tilt, there was no clear difference across visual cue types, although the order of contribution was similar to the SVV. These findings suggest that multiple visual cues to orientation are involved in postural control and imply different representations of vertical orientation across postural control and perception., Mar. 2022, 22, 4, 1, 11, Scientific journal, 10.1167/jov.22.4.1

  • Frontiers in Virtual Reality, Frontiers Media {SA}, Roles of the Retinotopic and Environmental Frames of Reference on Vection, Kanon Fujimoto; Hiroshi Ashida, Humans perceive self-motion using multisensory information, while vision has a dominant role as is utilized in virtual reality (VR) technologies. Previous studies reported that visual motion presented in the lower visual field (LoVF) induces stronger illusion of self-motion (vection) as compared with the upper visual field (UVF). However, it was still unknown whether the LoVF superiority in vection was based on the retinotopic frame, or rather related to the environmental frame of reference. Here, we investigated the influences of retinotopic and environmental frames on the LoVF superiority of vection. We presented a planer surface along the depth axis in one of four visual fields (upper, lower, right, or left). The texture on the surface moved forward or backward. Participants reported vection while observing the visual stimulus through a VR head mounted display (HMD) in the sitting posture or lateral recumbent position. Results showed that the visual motion induced stronger vection when presented in the LoVF compared with the UVF in both postures. Notably, the vection rating in LoVF was stronger in the sitting than in the recumbent. Moreover, recumbent participants reported stronger vection when the stimulus was presented in the gravitationally lower field than in the gravitationally upper field. These results demonstrate contribution of multiple spatial frames on self-motion perception and imply the importance of ground surface., 24 Nov. 2020, 1, Scientific journal, 10.3389/frvir.2020.581920

  • Frontiers in Psychology, Frontiers Media {SA}, Different Head-Sway Responses to Optic Flow in Sitting and Standing With a Head-Mounted Display, Kanon Fujimoto; Hiroshi Ashida, We investigated postural responses (head displacements) and self-motion perception (vection) to radial and lateral optic flows while sitting and standing by using a head-mounted display. We found that head displacement directions varied across postures. In the standing posture, radial optic flow generally produced the opposed head displacement against the perceived vection direction, consistent with the literature; however, in the sitting posture, the optic flow generally produced the following head displacement in the vection direction. In the standing posture, responses were evident soon after the onset of the optic flow presentation but became less clear in the latter half of a trial. The results, while less clear for lateral flows, were similar for both flow types. Our findings suggest partially distinct processes underlying vection and postural control., 06 Oct. 2020, 11, 577305, 577305, Scientific journal, True, 10.3389/fpsyg.2020.577305

  • i-Perception, Larger Head Displacement to Optic Flow Presented in the Lower Visual Field, Kanon Fujimoto; Hiroshi Ashida, Optic flow that simulates self-motion often produces postural adjustment. Although literature has suggested that human postural control depends largely on visual inputs from the lower field in the environment, effects of the vertical location of optic flow on postural responses are not well investigated. Here, we examined whether optic flow presented in the lower visual field produces stronger responses than optic flow in the upper visual field. Either expanding or contracting optic flow was presented in upper, lower, or full visual fields through an Oculus Rift head-mounted display. Head displacement and vection strength were measured. Results showed larger head displacement under the optic flow presentation in the full visual field and the lower visual field than the upper visual field, during early period of presentation of the contracting optic flow. Vection was strongest in the full visual field and weakest in the upper visual field. Our findings of lower field superiority in head displacement and vection support the notion that ecologically relevant information has a particularly important role in human postural control and self-motion perception., Nov. 2019, 10, 6, 2041669519886903, 2041669519886903, Scientific journal, True, 10.1177/2041669519886903

    2021年度は，主に(1)かわいさ知覚に関する研究知見の文献調査と(2)かわいさ知覚時の身体的反応生起に関する検証を行った。文献調査の成果としては，評論論文を執筆し現在審査中である。身体的反応生起の検証については，画像観察時の重心動揺と画像のかわいさ評定の相関関係を検証した。成人女性顔画像，乳幼児顔画像，人物以外の画像を観察している際の重心動揺を接近反応の指標として測定し，各画像の評定値との関連を調べたところ，女性参加者ではかわいさ評定との関連が見られ，特に成人女性顔のかわいさ評定と接近反応が負の相関を示した。一方で男性参加者ではかわいさ評定との関連は見られなかった。当該成果は国内外の学会で発表したうえで論文にまとめ現在審査中である。またかわいさ知覚時の身体的反応生起に関しては，他に瞳孔反応に着目し，画像のかわいさ評定と瞳孔変化率が相関していることを明らかにした。当該成果はすでに査読付き論文として公開されている。
    以上の結果から，かわいさ知覚時に身体的反応が生起することは明らかであるが，実験条件を今後さらに精査し，かわいさ知覚に伴う身体的反応の生起機序をより詳らかにすることを目指す。, kaken

    博士課程の学生によるVRゴーグルを用いた身体制御の研究は本課題に関わる有意義な成果となり、論文として出版することができた(Fujimoto & Ashida, 2022, JoV)。これまで、オプティックフローによる無意識的な姿勢制御と意識的な自己運動知覚（ベクション）の関係について研究を進めてきたが、姿勢制御には動的なオプティックフローだけではなく静止したシーンの情報も影響する。特に、視野全体が傾くことにより、立位姿勢の制御と垂直方向の知覚がともに影響される。VRゴーグルを着用して傾いたシーンを観察する実験の結果、頭部移動測定による姿勢制御と、垂直方向判断課題の結果はかなりよく似ていることがわかった。シーンの方向を規定する要因として90度周期の「フレーム」、180度周期の「水平線」、360度周期の「(オブジェクト)極性」の３つの周期からなる正弦波の組み合わせによるモデル(Dyde et al., 2006)が適用でき、垂直知覚に比して姿勢制御にはフレームの効果が若干大きいことが明らかになった。, kaken

Major findings: 1) we found that the spatial frequency dependency in speed perception is the basis of the recently created Spinner illusion (A. Ho & S. Anstis). 2) we found brain areas that are responsible in visual self motion perception, and re-discovered the white matter fascicle connecting these areas. 3) discovery of audio-visual interaction that is specific to looming motion and is dependent on spatial congruence. Dr van Tonder, who was initially a formal member of this project, has developed a computational model for anomalous motion illusions, which was presented at a conference but is still under development for publication., url
