Attentional processes play a complex and multifaceted role in the integration of input from different sensory modalities. However, whether increased attentional load disrupts the audiovisual (AV) integration of common objects that involve semantic content remains unclear. Furthermore, knowledge regarding how semantic congruency interacts with attentional load to influence the AV integration of common objects is limited. We investigated these questions by examining AV integration under various attentional-load conditions. AV integration was assessed by adopting an animal identification task using unisensory (animal images and sounds) and AV stimuli (semantically congruent AV objects and semantically incongruent AV objects), while attentional load was manipulated by using a rapid serial visual presentation task. Our results indicate that attentional load did not attenuate the integration of semantically congruent AV objects. However, semantically incongruent animal sounds and images were not integrated (as there was no multisensory facilitation), and the interference effect produced by the semantically incongruent AV objects was reduced by increased attentional-load manipulations. These findings highlight the critical role of semantic congruency in modulating the effect of attentional load on the AV integration of common objects.

Improving the accuracy and speed of choice in human-computer interactions via a subliminal priming effect 査読

Qi Dai, Lichang Yao, Yiyang Yu, Qiong Wu, Jiajia Yang, Satoshi Takahashi, Yoshimichi Ejima, Jinglong Wu

International Journal of Mechatronics and Automation 7 ( 2 ) 105 - 112 2020年8月

With the development of information processes, the interaction between humans and computers is everywhere in our daily life. As the level of human-computer interaction continues to rise, the cognitive load in human-computer interaction is also increasing, and thus, the operational error rate is rising. Subliminal communication technology refers to the use of appropriate methods to provide subliminal cues to convey supplementary information in an unconscious way. This method does not increase the burden on cognitive channels, but it improves people's abilities to recognise and make decisions. Therefore, we conducted a series of experiments on the subliminal priming effect to observe the feasibility of this idea. We used experimental psychophysical methods to demonstrate that the subliminal stimuli had a considerable impact on various cognitive processes and decision-making.

Eccentricity Effect of Deformation Detection for Radial Frequency Patterns With Their Centers at Fixation Point 査読国際共著

Yang Feng, Qiong Wu, Jiajia Yang, Satoshi Takahashi, Yoshimichi Ejima, Jinglong Wu, Ming Zhang

Perception 49 ( 8 ) 858 - 881 2020年8月

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：SAGE Publications

We measured the eccentricity effect of deformation thresholds of circular contours for two types of the radial frequency (RF) patterns with their centers at the fixation point: constant circular contour frequency (CCF) RF patterns and constant RF magnified (retino-cortical scaling) RF patterns. We varied the eccentricity by changing the mean radius of the RF patterns while keeping the centers of the RF patterns at the fixation point. Our peripheral stimulus presentation was distinguished from previous studies which have simply translated RF patterns at different locations in the visual field. Sensitivity for such shape discrimination fell off as the moderate and high CCF patterns were presented on more eccentric sites but did not as the low CCF patterns. However, sensitivity held constant as the magnified RF patterns were presented on more eccentric sites, indicating that the eccentricity effects observed for the high and moderate CCF patterns were neutralized by retinocortical mapping. Notably, sensitivity for the magnified RF patterns with large radii (4°–16°) presented in the peripheral field revealed a similar RF dependence observed for RF patterns with small radii (0.25°–1.0°) presented at the fovea in previous studies.

Tactile angle discriminability improvement: roles of training time intervals and different types of training tasks. 査読国際誌

Perceptual learning, which is not limited to sensory modalities such as vision and touch, emerges within a training session and between training sessions and is accompanied by the remodeling of neural connections in the cortex. However, limited knowledge exists regarding perceptual learning between training sessions. Although tactile studies have paid attention to between-session learning effects, there have been few studies asking fundamental questions regarding whether the time interval between training sessions affects tactile perceptual learning and generalization across tactile tasks. We investigated the effects of different training time intervals on the consecutive performance of a tactile angle discrimination (AD) task and a tactile orientation discrimination (OD) task training on tactile angle discriminability. The results indicated that in the short-interval training group, AD task performance significantly improved in the early stage of learning and nearly plateaued in the later stage, whereas in the long-interval training group, significant improvement was delayed and then also nearly plateaued in the later stage; additionally, improved OD task performance resulted in improved AD task performance. These findings suggest that training time interval affects the early stage of learning but not the later stage and that generalization occurs between different types of tactile tasks.NEW & NOTEWORTHY Perceptual learning, which constitutes important foundations of complicated cognitive processes, is learning better perception skills. We demonstrate that training time interval can affect the early stage of learning but not the later stage. Moreover, a tactile orientation discrimination training task can also improve tactile angle discrimination performance. These findings may expand the characteristics of between-session learning and help understand the mechanism of the generalization across tactile tasks.

Understanding of human sensory system will provide useful information's to the development of virtual reality (VR) technology that simulates a 3D virtual world and enables the generation of visual, audio, and haptic feedback for the full immersion of users. The present study is aimed to promote a better understanding of the visual system which is indispensable to recognize objects, face, animal, building, and natural scene in the visual environment in daily lives. We are focused to study difference in perception between foveal and peripheral visual system. We asked here about dependency of contrast discrimination of circular contour patterns on retinal eccentricity of the visual field, using standard (non-magnified) and cortically magnified stimuli. The contrast discrimination thresholds for the standard stimuli increased with increasing the retinal eccentricity. However, those for the cortically magnified stimuli remained constant irrespective of change of retinal eccentricity. We concluded that contrast discrimination thresholds, once scaling by cortically magnification transformation, were similar at all eccentricities.

Human unmyelinated tactile afferents (CT afferents) in hairy skin are thought to be involved in the transmission of affective aspects of touch. How the perception of affective touch differs across human skin has made substantial progress; however, the majority of previous studies have mainly focused on the relationship between stroking velocities and pleasantness ratings. Here, we investigate how stroking hardness affects the perception of affective touch. Affective tactile stimulation was given with four different hardness of brushes at three different forces, which were presented to either palm or forearm. To quantify the physical factors of the stimuli (brush hardness), ten naïve, healthy participants assessed brush hardness using a seven-point scale. Based on these ten participants, five more participants were added to rate the hedonic value of brush stroking using a visual analogue scale (VAS). We found that pleasantness ratings over the skin resulted in a preference for light, soft stroking, which was rated as more pleasant when compared to heavy, hard stroking. Our results show that the hairy skin of the forearm is more susceptible to stroking hardness than the glabrous of the palm in terms of the perception of pleasantness. These findings of the current study extend the growing literature related to the effect of stroking characteristics on pleasantness ratings.
