Aphantasia is a characteristic in which people with normal perception have difficulty constructing their imagination. Most previous studies have used the Vividness of Visual Imagery Questionnaire (VVIQ), with some using self-identification of the absence of visual imagery, but there is a discrepancy between the proportions of aphantasia in the popu...

We reviewed the properties of mental imagery in aphantasia—a condition whereby individuals have difficulties in forming mental imagery, even though their visual perception is intact. Individuals with aphantasia have demonstrated lower priming effects regarding visual imagery in a binocular rivalry paradigm; however, these individuals could still co...
Article
This study investigated the relationship between facial youthfulness and facial areas. The cognitive model reported previously shows that youthfulness is a complex impression composed of estimated age, lively impression, and clean impression. Eight participants rated these impressions of seven facial images using Scheffe’s paired comparison method....

Aphantasia is a condition firstly proposed by Zeman in which people show blind imagination despite no assumption of clinical factors. However, in Japan, there have been almost no reports of aphantasia. The present study reports a Japanese single-case of aphantasia, focusing on behavioral imagery abilities. Our case (KI), who realized his blind ima...

The word order that is easiest to understand in a language generally coincides with the word order most frequently used in that language. In Kaqchikel, however, there is a discrepancy between the two: the syntactically basic VOS incurs the least cognitive load, whereas SVO is most frequently employed. This suggests that processing load is primarily...
Article
This study aimed to construct a cognitive model of facial youthfulness. First, we investigated which higher-order impressions (e.g. lively, clean, etc.) compose youthfulness on the hypothesis that youthfulness is a complex impression. Then, we investigated which lower-order impressions (e.g. wrinkles, translucency, etc.) account for the constituent...

We investigated the effect of an observer's hand postures on visual motion perception using the stream/bounce display. When two identical visual objects move across collinear horizontal trajectories toward each other in a two-dimensional display, observers perceive them as either streaming or bouncing. In our previous study, we found that when obse...

Understanding the mechanism related to how people perceive reality is crucially important for the development of high-definition communication systems in multimedia contents. Various sensory information is well known to affect perceived reality from multimodal contents. For this purpose, it is important to present multimodal information with proper...
Article
This study investigated the influence of stereoscopic visual depth and body vibration on the high-level affective perception that concerns the senses of presence and verisimilitude. The multisensory content used in our experiment consisted of the 3D video recording of a passing train as seen from the side of the railroad, binaural recording of the...
Article
Spatial information inputted to the auditory periphery dramatically changes with a listener’s body movements relative to the sound source. Nevertheless, listeners can perceive a stable auditory environment and react appropriately to the sound source. This suggests that the spatial information is reinterpreted in the brain by being integrated with i...

We found that a hand posture with the palms together located just below the stream/bounce display could increase the proportion of bouncing perception. This effect, called the hands-induced bounce (HIB) effect, did not occur in the hands-cross condition or in the one-hand condition. By using rubber hands or covering the participants’ hands with a c...
Article
We investigated how auditory space would be represented during linear self-motion and visually-induced self-motion (vection) (Teramoto et al., 2012, 2014). The previous studies indicated that the subjective coronal plane (SCP) was displaced during forward self-motion, while during backward motion in the case of vection. The present study investigat...

Emotional processing that occurs partially in advance of perceptual processing is known as pre-perceptual emotional processing. The facilitation of sensory processing due to pre-perceptual emotional processing can be observed in visual search and attentional blink tasks. However, previous event-related potential studies have suggested that pre-perc...
Article
Previous studies have shown that the perceived duration of visual stimuli can be strongly distorted by auditory stimuli presented simultaneously. In this study, we examine whether sounds presented separately from target visual stimuli alter the perceived duration of the target's presentation. The participants' task was to classify the duration of t...
Conference Paper
We investigated whether visual spatial processing can be affected by the degree of preference for paintings. Firstly, the participants were required to manipulate a mouse and point to the location of the target that appeared at the periphery, following the paintings presented at center. After completing this task, the participants judged their pref...

Full-text available
This study investigated how auditory space is represented during linear self-motion. Results of several studies suggest that whether the listener's motion is active or passive affects sound localization. Therefore, we investigated whether the style of the self-motion affects the perceived auditory space. As the passive condition, observers were tra...

Temporal consistency between visual and auditory presentations is necessary for integration of visual and auditory information. Subjective simultaneity perception is more important than the synchrony of physical inputs for temporal consistency. Our previous studies have shown that audiovisual integration is difficult even if the visual and auditory...

Audio-visual integration interacts with attentional mechanisms. Additionally, salient auditory stimuli automatically draw attention to an audio-visual event, while spatial attention can modulate audio-visual integration. Attention induced by auditory inputs (sound-driven attention) facilitates visual perception. Similarly, visual attention improves...
Article
When a brief single flash is presented simultaneously with two brief beeps, the number of presented flashes is often perceived as two. This phenomenon is referred to as the fission illusion. Several effects related to the fission illusion have been investigated using both psychophysical and neurophysiological methods. The present study examined the...

We examined the effects of negative (anger, sadness, and disgust) and positive (happiness) stimuli on face recognition. We adopted the flicker paradigm composed of change-detection (Experiment A) and memory (Experiment B) tasks. In the change-detection task, each trial cycled through two displays separated by a blank display until a response was ma...
Conference Paper
Numerosity judgment of visual objects includes various perceptual and cognitive processes. Previous studies have indicated that there are two processes in numerosity judgmentsa subitizing process for up to three or four items and a counting process for over three or four items. These numerosity judgment processes are reported to reflect different t...

Even though auditory stimuli do not directly convey information related to visual stimuli, they often improve visual detection and identification performance. Auditory stimuli often alter visual perception depending on the reliability of the sensory input, with visual and auditory information reciprocally compensating for ambiguity in the other sen...
Article
Full-text available
Perception of self-motion is based on the integration of multiple sensory inputs, in particular from the vestibular and visual systems. Our previous study demonstrated that vestibular linear acceleration information distorted auditory space perception (Teramoto et al., 2012). However, it is unclear whether this phenomenon is contingent on vestibula...
Article
Auditory stimuli often facilitate visual perception. Audiovisual integration requires spatial and/or temporal proximity between visual and auditory stimuli; additionally, sensory processing speed affects the audiovisual integration process. In the present study we examined the relationship between processing speed and the auditory facilitation effe...

The present study investigates whether or not "a trace", which is linguistically hypothesized to be left behind by syntactic movement, is mentally created when a scrambled sentence in Japanese is processed. From past to present, the result or a self-paced reading experiment has supported the psychological reality of trace, but the result or a probe...
Article
Several studies have examined the effects of auditory stimuli on visual perception. In studies of cross-modal correspondences, auditory pitch has been shown to modulate visual motion perception. In particular, low-reliability visual motion stimuli tend to be affected by metaphorically or physically congruent or incongruent sounds. In the present st...

This report examines effects of the spatial complexity of configurations on visual short-term memory (VSTM) capacity for individuals from the general population differing on autism-spectrum quotient (AQ) scores. During each trial, nine-line segments with various orientations were arrayed in simple or complex configurations and presented in both mem...
Article
We are investigating how auditory space was represented during linear self-motion (Teramoto et al., 2013). Several studies have suggested that whether the listener's motion is active or passive affected sound localization (Hirahara et al., 2013). In the present study, therefore, we set up three conditions: active motion condition, passive motion co...

We investigated the effects of linear acceleration on auditory space representation. During self-motion, a short noise burst was presented from one of the loudspeakers aligned parallel to the motion direction when the listener's coronal plane reached a particular location (baseline). The effect of active and passive forward movement on perceived au...
Article
A startle reflex to a startle pulse is inhibited when preceded by a prestimulus. We introduced a key-press action (self-action) or an 85 dB noise burst as a prestimulus, followed by a 115 dB noise burst as a startle pulse. We manipulated temporal offsets between the prestimulus and the startle pulse from 30-1,500 ms to examine whether self-action m...
Article
The fission illusion is induced by multisensory (audio-visual) integration. In the present study, we assume that perceptual efficiency affects the fission illusion's rate because this illusion occurs in a short temporal range through the integration of visual and auditory information. The present study examined the effect of perceptual efficiency o...

We investigated the effects of listeners' head movements and proprioceptive feedback during sound localization practice on the subsequent accuracy of sound localization performance. The effects were examined under both restricted and unrestricted head movement conditions in the practice stage. In both cases, the participants were divided into two g...
Article
Perception of self-motion is based on integration of multiple sensory inputs, especially from the vestibular and visual systems. Our previous study demonstrated that vestibular information on linear acceleration distorted auditory space perception (Teramoto et al., 2012, PLoS ONE, 7(6), e39402). However, it is unclear whether this phenomenon is con...

Humans can perceive a stable auditory environment and appropriately react to a sound source, even when they are moving. This suggests that the inputs are reinterpreted in the brain, while being integrated with information on the movements. Although several studies have shown the influence of the vestibular semicircular canal signals on auditory loc...
