A highly sensitive person is known to have greater levels of sensory processing sensitivity (SPS) referring to a personality trait to exhibit high stimulation and arousal while processing subtle sensory signals. However, how SPS levels reflect the profile of sensitivity in exteroceptive and interoceptive sensory processing remains inadequately understood. Thus, we collected data using the Highly Sensitive Person Scale (HSPS), the Glasgow Sensory Questionnaire (GSQ), and the Body Perception Questionnaire-Short Form (BPQ-SF) from 600 Japanese adults, and examined their relationships. The results revealed that SPS levels, assessed by the HSPS, were significantly, positively correlated with hypersensitivity scores of the GSQ in several exteroceptive sensory domains. Further, SPS levels were positively correlated with sensitivity in interoceptive awareness assessed by the BPQ-SF; however, it does so scarcely. Our findings suggest that SPS levels reflect a subjective sensitivity to exteroceptive sensory processing regardless of sensory domains and narrowly to the interoceptive sensory processing.

The other-race effect indicates a perceptual advantage when processing own-race faces. This effect has been demonstrated in individuals’ recognition of facial identity and emotional expressions. However, it remains unclear whether the other-race effect also exists in multisensory domains. We conducted two experiments to provide evidence for the other-race effect in facial speech recognition, using the McGurk effect. Experiment 1 tested this issue among East Asian adults, examining the magnitude of the McGurk effect during stimuli using speakers from two different races (own-race vs. other-race). We found that own-race faces induced a stronger McGurk effect than other-race faces. Experiment 2 indicated that the other-race effect was not simply due to different levels of attention being paid to the mouths of own- and other-race speakers. Our findings demonstrated that own-race faces enhance the weight of visual input during audiovisual speech perception, and they provide evidence of the own-race effect in the audiovisual interaction for speech perception in adults.

<title>Abstract</title>This study investigated the difference in the McGurk effect between own-race-face and other-race-face stimuli among Japanese infants from 5 to 9 months of age. The McGurk effect results from infants using information from a speaker’s face in audiovisual speech integration. We hypothesized that the McGurk effect varies with the speaker’s race because of the other-race effect, which indicates an advantage for own-race faces in our face processing system. Experiment 1 demonstrated the other-race effect on audiovisual speech integration such that the infants ages 5–6 months and 8–9 months are likely to perceive the McGurk effect when observing an own-race-face speaker, but not when observing an other-race-face speaker. Experiment 2 found the other-race effect on audiovisual speech integration regardless of irrelevant speech identity cues. Experiment 3 confirmed the infants’ ability to differentiate two auditory syllables. These results showed that infants are likely to integrate voice with an own-race-face, but not with an other-race-face. This implies the role of experiences with own-race-faces in the development of audiovisual speech integration. Our findings also contribute to the discussion of whether perceptual narrowing is a modality-general, pan-sensory process.

<title>Abstract</title>
While visual information from facial speech modulates auditory speech perception, it is less influential on audiovisual speech perception among autistic individuals than among typically developed individuals. In this study, we investigated the relationship between autistic traits (Autism-Spectrum Quotient; AQ) and the influence of visual speech on the recognition of Rubin’s vase-type speech stimuli with degraded facial speech information. Participants were 31 university students (13 males and 18 females; mean age: 19.2, SD: 1.13 years) who reported normal (or corrected-to-normal) hearing and vision. All participants completed three speech recognition tasks (visual, auditory, and audiovisual stimuli) and the AQ–Japanese version. The results showed that accuracies of speech recognition for visual (i.e., lip-reading) and auditory stimuli were not significantly related to participants’ AQ. In contrast, audiovisual speech perception was less susceptible to facial speech perception among individuals with high rather than low autistic traits. The weaker influence of visual information on audiovisual speech perception in autism spectrum disorder (ASD) was robust regardless of the clarity of the visual information, suggesting a difficulty in the process of audiovisual integration rather than in the visual processing of facial speech.

The Family Allocentrism Scale (FAS) was developed to assess individual differences in allocentrism-idiocentrism with reference to the family. To date, no prior study has adequately investigated the psychometric properties of the Japanese version of the FAS in Japanese samples, although Japanese culture is considered as a symbol of an interdependent (or collectivist) culture. This study attempted to demonstrate the validity of the factor structure and the convergent validity of the Japanese version of the FAS in a sample of Japanese adults. The results of the confirmatory factor analysis showed a lack of fit of the one-factor model for all FAS items but the fit improved to the acceptable level if some items with low factor loadings were removed. The internal consistency measure (Cronbach's alpha) of the FAS indicated an acceptable level of reliability. The results also showed that the FAS scores were closely related to the scores of horizontal collectivism, vertical collectivism, and interdependence. Our findings indicate the validity and reliability of the Japanese version of the FAS, thereby providing a validated tool for the investigation of cross-cultural differences in family allocentrism-idiocentrism.

Significance: It has been reported that children with attention-deficit hyperactivity disorder (ADHD) have impairment in the recognition of angry but not of happy facial expressions, and they show atypical cortical activation patterns in response to facial expressions. However, little is known about neural mechanisms underlying the impaired recognition of facial expressions in school-aged children with ADHD and the effects of acute medication on their processing of facial expressions. Aim: We aimed to investigate the possibility that acute administration of methylphenidate (MPH) affects processing of facial expressions in ADHD children. Approach: We measured the hemodynamic changes in the bilateral temporo-occipital areas of ADHD children observing the happy and angry facial expressions before and 1.5 h after MPH or placebo administration in a randomized, double-blind, placebo-controlled, crossover design study. Results: We found that, regardless of medication, happy expressions induced increased oxyhemoglobin (oxy-Hb) responses in the right inferior occipital region but not in the superior temporal region. For angry expressions, oxy-Hb responses increased after MPH administration, but not after placebo administration, in the left inferior occipital area, whereas there was no significant activation before MPH administration. Conclusions: Our results suggest that (1) ADHD children consistently recruit the right inferior occipital regions to process happy expressions and (2) MPH administration to ADHD children enhances cortical activation in the left inferior occipital regions when they process angry expressions.

The human perceptual system enables us to extract visual properties of an object's material from auditory information. In monkeys, the neural basis underlying such multisensory association develops through experience of exposure to a material
material information could be processed in the posterior inferior temporal cortex, progressively from the high-order visual areas. In humans, however, the development of this neural representation remains poorly understood. Here, we demonstrated for the first time the presence of a mapping of the auditory material property with visual material ("Metal" and "Wood") in the right temporal region in preverbal 4- to 8-month-old infants, using near-infrared spectroscopy (NIRS). Furthermore, we found that infants acquired the audio-visual mapping for a property of the "Metal" material later than for the "Wood" material, since infants form the visual property of "Metal" material after approximately 6 months of age. These findings indicate that multisensory processing of material information induces the activation of brain areas related to sound symbolism. Our findings also indicate that the material's familiarity might facilitate the development of multisensory processing during the first year of life.

The McGurk effect, which denotes the influence of visual information on audiovisual speech perception, is less frequently observed in individuals with autism spectrum disorder (ASD) compared to those without it
the reason for this remains unclear. Several studies have suggested that facial configuration context might play a role in this difference. More specifically, people with ASD show a local processing bias for faces—that is, they process global face information to a lesser extent. This study examined the role of facial configuration context in the McGurk effect in 46 healthy students. Adopting an analogue approach using the Autism-Spectrum Quotient (AQ), we sought to determine whether this facial configuration context is crucial to previously observed reductions in the McGurk effect in people with ASD. Lip-reading and audiovisual syllable identification tasks were assessed via presentation of upright normal, inverted normal, upright Thatcher-type, and inverted Thatcher-type faces. When the Thatcher-type face was presented, perceivers were found to be sensitive to the misoriented facial characteristics, causing them to perceive a weaker McGurk effect than when the normal face was presented (this is known as the McThatcher effect). Additionally, the McGurk effect was weaker in individuals with high AQ scores than in those with low AQ scores in the incongruent audiovisual condition, regardless of their ability to read lips or process facial configuration contexts. Our findings, therefore, do not support the assumption that individuals with ASD show a weaker McGurk effect due to a difficulty in processing facial configuration context.

The McGurk effect is a well-known illustration that demonstrates the influence of visual information on hearing in the context of speech perception. Some studies have reported that individuals with autism spectrum disorder (ASD) display abnormal processing of audio-visual speech integration, while other studies showed contradictory results. Based on the dimensional model of ASD, we administered two analog studies to examine the link between level of autistic traits, as assessed by the Autism Spectrum Quotient (AQ), and the McGurk effect among a sample of university students. In the first experiment, we found that autistic traits correlated negatively with fused (McGurk) responses. Then, we manipulated presentation types of visual stimuli to examine whether the local bias toward visual speech cues modulated individual differences in the McGurk effect. The presentation included four types of visual images, comprising no image, mouth only, mouth and eyes, and full face. The results revealed that global facial information facilitates the influence of visual speech cues on McGurk stimuli. Moreover, individual differences between groups with low and high levels of autistic traits appeared when the full-face visual speech cue with an incongruent voice condition was presented. These results suggest that individual differences in the McGurk effect might be due to a weak ability to process global facial information in individuals with high levels of autistic traits.

Whether audiovisual inputs are integrated or separately processed depends on the congruency, e.g., temporal synchrony, between them. Some studies have assumed that the familiarity to the stimuli influences on the integration process. Here, we investigated how familiarity to the speaker’s face and voice influences audiovisual temporal binding processing. In the experiment, we presented the audiovisual speech by familiar and unfamiliar faces with various A/V onset asynchronies within +/- 800 ms. We asked participants to judge synchrony of audiovisual stimuli, then calculated the temporal binding window (TBW). The results showed that the width of the TBW in the familiar and unfamiliar conditions were comparable, which indicates little impact of face familiarity on the temporal binding processing. We discussed potential reasons for our results in reference to the cortical network for processing temporal binding of audiovisual inputs.

We feel unusual grotesqueness and distortion when seeing several faces rapidly presented in peripheral vision (FFDE). Here, to reveal the effect of facial parts, we investigate the intensity of FFDE using partially presented faces. In the experiment, a series of face pictures were presented for 10 seconds while switching pictures every 250 ms. We presented 5 conditions: whole-face, upper-half, eye-alone, eye-removed, and contourless-face. Participants were asked to keep pressing a button when they felt distortion of faces and to rate the intensity of distortion and uncanniness after stimulus presentation. We found that the intensity of FFDE depended on the presented facial parts: whole-face > contourless-face > upper-half > eye-removed > eye-alone. The FFDE latency also differed by condition, though it diverged from the order of intensity rating. These results suggest that holistic face processing is involved in FFDE and that there are different determinants of intensity and latency of FFDE.

The McGurk effect is a perceptual phenomenon that demonstrates interaction between hearing and vision in speech perception. This effect may be experienced when a visual of the production of a phoneme (/ka/) is dubbed with a sound recording of a different phoneme being spoken (/pa/),&nbsp;wherein the perceived phoneme is often the third,&nbsp;intermediate phoneme (/ta/). In the present study, we examined the potential individual differences in the McGurk effect among healthy students. The results suggested that people with higher scores for autistic traits might report more /ta/ responses (vision-audio fused responses) in the McGurk condition (visually /pa/ but auditory /ka/) over all experiments. This indicates that such people might show a weak support from the motor system for audio- visual speech perception.<br>
