This study examined whether tactile information influences tactile impressions induced by visual textures. We used 22 natural images of materials (22.4°×22.4°; presentation duration of 100 ms) and asked participants to report the intensity of four types of tactile impressions described in onomatopoeias and an adjective (i.e., “zarazara” (coarsely), “tsurutsuru” (slipperily), “kasakasa” (dryly), and “komakai” (fine)) by making notations on each line-scale with check marks. We asked the participants to evaluate the visual textures during or after touching an index finger to a rotating cylinder (7.7 cm in diameter; approximately 10 rps) with regularly indented surfaces (visuo-tactile condition), and without touching the rotating cylinder (visual condition). The results revealed that, when the tactile stimulus was presented simultaneously with the visual textures, tactile impressions of them were evaluated higher in the visuo-tactile condition than in the visual condition. Particularly, three of the four tactile impressions (i.e., “zarazara”, “kasakasa”, and “komakai”) were strongly affected by the tactile stimulation. In contrast, when the tactile stimulus was presented prior to the visual textures for twenty seconds, the three impressions were evaluated lower in the visuo-tactile condition than in the visual condition, possibly resulting from a cross-modal aftereffect of adaptation to the tactile stimulus. Moreover, these effects were observed regardless of the similarity of tactile impressions between the visual and tactile stimuli. These results indicate that tactile information influences tactile impressions induced by visual textures. This effect might occur at the level of sensory processing.

In this article, we present our neuroimaging studies by functional Magnetic Resonance Imaging (fMRI) about the brain mechanism of cognition toward elucidation of pathophysiology in depression. The first and second data show the brain mechanism (Kurosaki et al., 2005; Ueda et al., 2003) related to dysfunctional beliefs and systematic cognitive errors identified by Beck (1967), and the third is that (Tanaka et al., 2004) related to differential activation hypothesis proposed by Teasdale (1988). Lastly, we also show the change of brain function before and after cognitive behavioral group therapy (CBGT). Depressed patients before the CBGT showed attenuated activation in the dorsolateral prefrontal cortex, parietal cortex, and striatum were activated during the task. After the CBGT, the brain activation in good responders was restored as same as that in healthy control. However, in poor responder, there was no change on brain activation between before and after CBGT.

Information derived from facial and vocal nonverbal expressions plays an important role in social communication in the real and virtual worlds. In the present study, we investigated cultural differences between Japanese and Dutch participants in the multisensory perception of emotion. We used a face and voice that expressed incongruent emotions as stimuli and conducted two experiments. We presented either the face or voice in Experiment 1, and both the face and voice in Experiment 2. We found that both visual and auditory information were important for Japanese participants judging in-group stimuli, while visual information was more important for other combinations of participants and stimuli. Additionally, we showed that the in-group advantage provided by auditory information was higher in Japanese than Dutch participants. Our findings indicate that audio-visual integration of affective information is modulated by the perceiver's cultural background, and that there are cultural differences between in-group and out-group stimuli.

A fundamental challenge in visual psychology and neuroscience is to understand how 2D retinal inputs are reconstructed into a coherent and stable 3D visual world. In this review paper, I will introduce our recent fMRI studies on 3D depth perception in which we investigated 1) how and where in the brain multiple depth cues are integrated, 2) the development of visual 3D cue integration at the level of neural representation, and 3) how the outputs of neurons responding to local and simple elements are progressively transformed to encode the critical features of spatially-extensive objects. Based on those studies, I will discuss on the roles of dorsal visual areas to infer the computational hierarchy that supports the 3D estimation, a property important for recognizing our visual world and planning actions. Furthermore, I would like to discuss how 3D vision psychology/neuroscience studies can contribute to the engineering fields to develop future display devices and information and communication technologies.

In this research, we investigated the function of human eye-gaze perception and control system. The whites of human eyes produce a strong contrast with the pupils, and in light of this fact, detection of the eye-gaze direction is relatively easy to do. Our result in Experiment 1, however, showed that the perceived eye-gaze direction is affected not only by the eyes but also by the direction of the whole head. From the perceived position, the actual gazed position can be estimated by a linear function model. From the result of Experiment 2, we found that the head and eye movements of perceiver are also systematically affected by the looker's head rotation. Additionally, in the MRI imaging study in Experiment 3, it was shown that the rotation center of the eyeball when the participant gazed at various points was located backward, and the rotation angle was asymmetric on both eyes.

Time-varying patterns such as flickering lights can cause discomfort and induce seizures in photosensitive observers. An understanding of the temporal characteristics of visual discomfort is therefore important from both scientific and practical viewpoints. The purpose of this paper is to review existing studies on the impact of temporal characteristics on discomfort. Two related factors have been suggested as predictors of discomfort caused by time-varying patterns: (1) excessive contrast energy at the medium temporal frequencies to which the visual system is generally most sensitive, and (2) temporal deviations from the natural (1/f) statistical characteristic. These effects mirror the visual discomfort caused by spatial patterns, in some ways but not all. The interaction between spatial and temporal parameters needs to be investigated to clarify the factors underlying visual discomfort.

Point makeup perceptually affects overall facial color; for example, it takes on the tinge of the eye shadow color. This study preliminarily confirmed the assimilation effect by lipstick colors and the relationship between perceptual and esthetic measures. Four typical lipstick colors, red, pink, orange, and violet, were utilized. An averaged face varied based on two factors, lightness (lighter and darker) and hue (reddish and yellowish), was examined. Twenty-four females assessed the faces in terms of perceptual hue (redness for the reddish faces and yellowness for the yellowish faces), perceptual lightness, dullness, and looking-goodness via paired comparisons. Consequently, an assimilation effect of lipstick's hue on perceptual complexion was confirmed. However, a perceptual change in lightness could not be explained by assimilation or contrast; the redness of lipsticks enhanced the perceptual lightness of complexion. Dullness negatively correlated not only with perceptual lightness but also with perceptual redness of faces and physical redness of lipsticks. Looking-goodness clearly correlated with perceptual redness of faces and each lipstick color had its own effect.

People prefer unambiguity to ambiguity in decision making under ambiguity. This phenomenon, known as “ambiguity aversion,” is thought to be influenced by environmental and psychological factors. The present research demonstrated the effects of choice opportunity (the availability of choice of cards), competition (the presence vs. absence of a competitor), and stimulus familiarity (familiar playing cards vs. unfamiliar tarot cards) on choice of ambiguity. Participants preferred the ambiguous deck of cards when they were allowed to choose playing cards. In the tarot-card task, however, they did not show a preference for the ambiguous deck even if they could choose the cards by themselves. The competition factor had no effect on the participants' choice. These findings indicate that choice opportunity and stimulus familiarity affect decision making under ambiguity.

We propose a method to solve problems that are difficult to solve only from engineering knowledge by using phenomena modeled in psychology fields such as “sensory-motor loop” and “sensory-perception mechanism.” We will be explained, a method to induce behavior without paying attention by the vestibular electric stimulation method that causes a physical response despite unconscious stimulation. And, a method of communicating/learning nonverbal skills by causing the body response under consciousness by synthesizing and switching first-person visual stimuli. The last, A highly realistic stereoscopic display method that makes it possible to significantly lower the cost of the apparatus than conventional methods by adding parallax to multi slit view.

Why do we utilize artificial categories in investigating concepts and categories? No clear answer has been given to this question. Then, how can we claim the validity of artificial categories? This paper makes logical, set theoretical, and psychological consideration around this theme. The major conclusions are: 1) Artificial categories (concepts) should be homomorphic images of existent categories (concepts). 2) Some functional (or abstract) concepts cannot be represented by sets of artificial stimuli; this means artificial categories are not all-purpose tools. 3) As for the types of categories and concepts which can be represented by sets, a) intension and extension, b) the number of instances, and c) modes of uncertainty both in intension and extension, are problems of critical importance. In particular, we must make explicit representational formats for the processing of uncertainty and logical structures inherent in concepts and categories. Finally, 4) people can handle conceptual information in completely differently ways: they are sometimes naive statisticians, sometimes naive scientists, according to the task demands and the data available to them.
