The Relationship Between Interoceptive Sensibility and Perceptual Switching
2024 IEEE 15th International Conference on Cognitive Infocommunications (CogInfoCom)
Year: 2024 | Conference Paper |
Previous studies have shown that various individual characteristics are related to perceptual switching in perceptual competition situations, but no research has examined its relationship with interoception. Interoception may influence perceptual switching by affecting awareness of neurophysiological responses that predict switching. This study investigated the relationship between perceptual swit...Show More
Visual Images of Contaminated Objects and Attentional Shift
2024 Tenth International Conference on Communications and Electronics (ICCE)
Year: 2024 | Conference Paper |
Although we expect AI robots for cleaning work to clean the contaminated areas, physically contaminated areas do not always match what we perceive to be contaminated. Thus, to provide us with a more comfortable environment, it is necessary to explore what kinds of objects or situations humans feel contaminated and affect our actual responses, regardless of whether it is physically contaminated. In...Show More

Do Fictive Sexual Orientations Induce In-Group Bias in Emotion Recognition?
2023 27th International Computer Science and Engineering Conference (ICSEC)
Year: 2023 | Conference Paper |
Deep learning techniques can now recognize sexual orientation from faces pictures more accurately than humans (70% vs. 60%). This advance in artificial intelligence can be problematic due to its lack of accuracy and the natural in-group bias of humans. More visible social characteristics (race, age, or gender) are known to induce such biases especially when it comes to emotion recognition. However...Show More

Kae Mukai;Ryoji Onagawa;Takumi Tanaka;Katsumi Watanabe;Kazutoshi Kudo
2020 12th International Conference on Knowledge and Smart Technology (KST)
Year: 2020 | Conference Paper |
In sprint athletics, the reaction time (RT; the time from the start signal to running onset) is one of the important factors determining performance. As RT is shorter, performance (i.e., total time) would be better. However, when RT is less than or equal to 100 ms, it is considered the premature start under the current regulations, leading to disqualification. Therefore, athletes need to decide on...Show More
Self-initiation of visual object motion has little influence on visual mislocalization by auditory stimuli

Sense of agency (SoA) is the subjective feeling that a person causes a change in the external world. The influence of SoA on crossmodal integration has not yet examined thoroughly. We investigated the effects of auditory stimuli on visual localization and its interaction with SoA. In Experiment 1, participants localized the disappearing position of a moving dot while hearing a continuous sound. Th...Show More
Attractive faces are rewarding irrespective of face category: Motivation in viewing attractive faces in Japanese viewers
2020 12th International Conference on Knowledge and Smart Technology (KST)
Year: 2020 | Conference Paper |
Cited by: Papers (2)
Attractive faces have reward value for beholders, and thus people are motivated to view them. The incentive salience of attractive faces has been measured by using a pay-per-view key-pressing paradigm, wherein participants change the viewing time of a presented face image. For example, it was reported that male and female viewers were motivated to view attractive opposite-sex faces and cute infant...Show More
Size-numerosity interaction depends retinal rather than perceived size
2020 12th International Conference on Knowledge and Smart Technology (KST)
Year: 2020 | Conference Paper |
Walsh [1] has put forward an interesting theory ‘A Theory of Magnitude’ (AToM), which propounds shared visual processes for various quantity perceptions such as time, space and number. Supporting the AToM, the number of dots surrounded by smaller circles are perceived to be more numerous than dots surrounded by larger circles [2]. To examine the processing level of this size-numerosity interaction...Show More

Year: 2019 | Conference Paper |
Cited by: Papers (3)
Cognitive biases are a central element of human cognition. One of the biases that intriguing cognitive scientist and psychologist most would be Theory of Mind, the cognitive capacity to ascribe mental states to others, animals, and even non-living entities. According to previous studies on mind perception, mental states people perceive can be classified into two categories, “Experience” and “Agenc...Show More
Color-Shape Association in Chinese People
2019 11th International Conference on Knowledge and Smart Technology (KST)
Year: 2019 | Conference Paper |
Cited by: Papers (1)
Previous studies showed that non-synesthetic Japanese individuals systematically associate certain shapes with particular colors (i.e., circle-red, triangle-yellow, and square-blue). Those color-shape associations could be explained by semantic sensory correspondence between color and shape dimensions. In the present study, we examined whether neuro-typical Chinese individuals establish some color...Show More

Antonio Rei Fidalgo;Kohshe Takahashi;Aiko Murata;Katsumi Watanabe
2018 10th International Conference on Knowledge and Smart Technology (KST)
Year: 2018 | Conference Paper |
It has been reported that when a congruent natural sound precedes briefly presented visual stimuli, it promotes performance in psychophysics detection tasks. Onomatopoeias refer to words that phonetically mimic or suggest actual sounds. Onomatopoeic words are a form of sound symbolism and are frequently used in Japanese language. In this study, we examined whether the presentation of spoken Japane...Show More
FFAB—The Form Function Attribution Bias in Human–Robot Interaction
Kerstin S. Haring;Katsumi Watanabe;Mari Velonaki;Chad C. Tossell;Victor Finomore
People seem to miscalibrate their expectations and interactions with a robot. When it comes to robot design, the anthropomorphism level of the robot form (appearance) has become an increasingly important variable to consider. It is argued here that people base their expectations and perceptions of a robot on its form and attribute functions which do not necessarily mirror the true functions of the...Show More

Ethical considerations of gendering very humanlike androids from an interdisciplinary perspective
2017 26th IEEE International Symposium on Robot and Human Interactive Communication (RO-MAN)
Year: 2017 | Conference Paper |
Cited by: Papers (2)
A large proportion of “very humanlike” androids are assigned aesthetics typically associated with femininity. Ethical and discriminatory issues have yet to be given in-depth attention in procedural literature. This position paper suggests that implicitly viewing humanlike robots as agents that could, in future, substitute “undesirable” and/or exploitable humans may affect not just the robots' desi...Show More
Impacts of cue reliability and explicit instruction on visual attention
2017 9th International Conference on Knowledge and Smart Technology (KST)
Year: 2017 | Conference Paper |
It has been known that effects of visual attention are modulated by cue validity (i.e., proportion of valid and invalid condition in a certain block). The present study aimed at examining whether the benefits (i.e., the differences of reaction times in the valid and invalid condition) were linear as a function of cue reliability. We also examined effects of explicit instruction of information rega...Show More
Relations between personality traits and empathy for social pain and physical pain
2017 9th International Conference on Knowledge and Smart Technology (KST)
Year: 2017 | Conference Paper |
Empathy for social pain (e.g., that caused by social exclusion) may be crucial for social bonding because it allows to understand others' feeling and facilitate pro-social behavior such as consolation. Studies have indicated the relationship between personality traits and empathy for physical pain. However, few studies have addressed the personality traits that are related to empathy for social pa...Show More
