19. Tomomi Koizumi, Hiroyuki ITO, Shoji Sunaga, Masaki Ogawa, Directional Bias in the Perception of Cast Shadows, i-Perception, 10.1177/2041669516682267, 1-17, 2017.01, Previous studies have demonstrated that the perception of shading is based upon assumptions about lighting direction, for example, light from above. However, it is not clear whether these assumptions are used in the perception of cast shadows. Moreover, it is unclear whether a perceptual interaction exists between shading and cast shadows because until now they have been studied separately. In this study, we investigated through three experiments whether the light-from-above (or another direction) assumption is used in interpreting ambiguous cast shadows, and whether shading information influences the interpretation of cast shadows. Our results indicate the existence of the light-from-above assumption in interpreting cast shadows. Consistent shading information enhanced the interpretation, and judgments of lighting direction were also based on both cast shadow and shading information. However, the perceptual determination of shape from shading was relatively independent of the cast shadow interpretation or the lighting direction judgments of the scene..

Fourteen undyed fabrics made of different fiber materials with various weaves and a knit structure were selected for the experimental samples. Images of the surfaces of the samples were recorded through a microscope with incident light and 45 degrees and receiving light of 0, 15, 30, 45, and 60 degrees. The reflected light was separated into specular and diffuse components using polarized filters, based on the dichromatic reflection model. The reflected light separated were visualized to show anisotropy reflections.
For the cotton fabrics, the specular reflection was observed only at the specular angle. For silk fabrics and other filaments, however, the specular component appeared at all receiving light angles, and the intensities obtained from synthetic fabrics and rayon were remarkable.
The intensities of the reflected components showed anisotropy depending on the observation direction of the fabrics. The apparent separation of yarns was narrower for the larger receiving light angles for various structures of weave and knit. This phenomenon may induce the change of the specular components of the light reflected from various surfaces with different normal direction, depending on the yarn and fibers, into the diffuse component of the reflected light. It is thus presumed that the main reason for the intense reflection observed at the receiving light angle, which is larger than the specular angle, must be due to the light reflection from the local surfaces present on the fabric textures, which is unlikely to occur on metal having a smooth surface..

Although the dichromatic simulation could qualitatively predict reaction times for color-defective observers, the
reaction times for color-defective observers tended to be longer than those of the trichromatic observers in
Experiment 1. In Experiment 2, we showed that a reduction of purity excitation of simulated colors can provide a good
prediction. Further, we propose an adaptive dichromatic simulation model based on the color differences between a
simulated target color and simulated distractor colors in order to obtain a better quantitative prediction of reaction times
in the visual search task for color defects..

, 10.1007/s00221-012-3083-y, 291, 235-244, 2012.03, The present study utilized two separate experiments
to demonstrate that illusory self-motion (vection) can
be induced/modulated by cognition. In the Wrst experiment,
two curved lines, which simulated road edges seen while
driving at night, were employed. Although the lines
induced adequate strength of forward vection, when one of
the lines was horizontally reversed, vection was signiWcantly
reduced. In the second experiment, two static converging
lines with moving characters, which simulated side
edges of a straight road with a traYc sign, were utilized.
The road sign moved only during the Wrst 5 s. After the sign
disappeared, only static lines or a blank screen were able to
induce vection. These results suggested that vection was
largely aVected by cognitive factors and that vection could
be induced by implicit motion stimuli..

Takeharu Seno, Masaki Ogawa, Hiroyuki Ito, Shoji Sunaga, Consistent air flow to the face facilitates vection, Perception, 40, 10, pp.1237-1240, 2011.10, We examined whether a somatosensory cue suggesting forward self-motion facilitated vection. We provided a consistent air flow to subjects’ faces by using an electric fan. Vection strength was increased when the air flow was provided.

Takeharu Seno, Shuichiro Taya, Hiroyuki Ito, Shoji Sunaga, The mental number line in depth revealed by vection, Perception, 40, 10, pp.1241-1244, 2011.10, To explore how numbers are represented in depth in our mental space, we asked participants to sequentially speak random numbers while they observed forward/backward vection. We found that participants tended to generate larger numbers when they perceived backward self-motion. The results suggest that numerical magnitudes were topographically mapped onto our mental space from front to rear in an ascending order. .
35. Go Matsumoto, Shoji Sunaga, Takeharu Seno, Contribution of colour and texture information to the recognition of
natural objects, Proceedings of the International Colour Association AIC Color 2011 Zurich, pp.564-567, 2011.06, Various visual attributes i.e. shape, colour, and texture etc, contribute to the recognition of natural
objects. The colours of natural objects which we memorize are known as the memory colours of
the object. It is well known that memory colours have higher saturation than the colours of the real
natural objects have. In most of the past studies about memory colour, uniformly-coloured patches
were used as stimuli, and the interaction between texture and memory colour wasn’t investigated.
In this study, we investigated whether texture information of a natural object had an influence on
memory colour of the object or not. We measured the plausibility of colour with or without texture
information of a cabbage and a piece of a watermelon. The results showed that the most plausible
colour for the coloured textured patch had lower saturation than that for the uniform patch had.
The colour region which provided high plausibility evaluations was smaller for the coloured
textured patch than for the uniformly-coloured patch. These results suggest the addition of texture
information restricts the colour region which provides high plausibility as the colour of the natural
object..
36. Tomomi Ogura, Shoji Sunaga, Takeharu Seno, The evaluation of dichromatic simulation by a visual search task, Proceedings of the International Colour Association AIC Color 2011 Zurich, pp.617-620, 2011.06, Dichromatic simulations (Brettel et al. 1997) are used widely in social and educational
environments. We evaluated the validity of dichromatic simulation by using a visual search task.
The stimulus images consisted of 13 coloured disks (one target and 12 distractors). Two colours
were assigned to 6 disks as distractor, respectively. Six trichromats and three strongly anomalous
trichromats participated in this experiment. The observer’s task was to detect the target colour
which was different from other disks as soon as possible. The reaction times (RTs) of the
dichromatic simulated colour stimulus for the trichromats were qualitatively similar to those of
the original colour stimulus for the anomalous trichromats. However, the RTs of the anomalous
trichromats tended to be longer than those of normal trichromats in some particular colour
combinations. Thus there is a possibility that the simulation overestimates the dichromats’ colour
detection. We can conclude that the simulation of the dichromats does not always agree with the
real dichromatic people’s colour perception..
37. Shoji Sunaga, Yellow-blue colour discrimination in red-green colour deficiency, Proceedings of the International Colour Association AIC Color 2011 Zurich, pp.759-762, 2011.06, We measured the colour discrimination thresholds on the equal-luminance colour plane of
CIE1976u’v’ UCS diagram for trichromats and red-green colour-deficient trichromats. We
compared between their thresholds in the yellow-blue direction. The results showed that the
thresholds in yellow-blue colour changes for the red-green colour-deficient trichromats were not
always larger than those for the normal trichromats. Further, our data suggest that the poor ability
of the yellow- blue colour discrimination for the trichromats was caused by the interaction between
the L-M mechanism and the S mechanism, although the S mechanism acts in the same way for
both the red-green colour-deficient observers and the normal trichromatic observers..

39. Takeharu Seno, Hiroyuki Ito, Shoji Sunaga, Self-motion perception compresses time experienced in return travel, Perception, 40, 4, pp.497-499, 2011.04, It is often anecdotally reported that time experienced in return travel (back to the start
point) seems shorter than time spent in outward travel (travel to a new destination). Here, we report
the first experimental results showing that return travel time is experienced as shorter than the
actual time. This discrepancy is induced by the existence of self-motion perception..
