It has been reported that visual statistical learning (VSL) is facilitated in skewed distributions. However, it remains unclear whether enhancement of VSL in Zipfian distributions is due to consciousness of the regularities presented at high frequency. This study addressed this issue. We measured participants' subjective confidence in regularities…

Previous cross-cultural research has described two different attention styles: a holistic style, characterized by context-sensitive processing, generally associated with interdependent cultural contexts, and an analytic style, a higher focus on salient objects, generally found in independent cultural contexts. Though a general assumption in the…

Early childhood is marked by significant developmental changes in the ability to recognize facial expressions. However, since the COVID-19 outbreak, people have been wearing masks more frequently during social interactions which may hamper the recognition of facial expressions. This study examines whether preschoolers recognize the facial…

A weaker McGurk effect is observed in individuals with autism spectrum disorder (ASD); weaker integration is considered to be the key to understanding how low-order atypical processing leads to their maladaptive social behaviors. However, the mechanism for this weaker McGurk effect has not been fully understood. Here, we investigated (1) whether…

We can incidentally learn regularities in a visual scene, and this kind of learning facilitates subsequent processing of similar scenes. One example of incidental learning is referred to as "contextual cueing," a phenomenon in which repetitive exposure to a particular spatial configuration facilitates visual search performance in the…

The present study investigated how the eye contact perception of ingroup and outgroup faces by Japanese adults with high-functioning autism spectrum disorder differed from that of age-, sex-, and IQ-matched typically developing individuals. The autism spectrum disorder and typically developing individuals were equally likely to perceive subtly…

Purpose: This study tested the hypothesis that audiovisual training benefits children more than it does adults and that it improves Japanese-speaking children's English /r/-/l/ perception to a native-like level. Method: Ten sessions of audiovisual English /r/-/l/ identification training were conducted for Japanese-speaking adults and children.…

This study investigated age differences in the utilization of visually contrastive information (i.e., differently colored identical objects) for temporary referential ambiguity resolution during spoken sentence comprehension. Five- and 6-year-old Japanese children and adults listened to sentences that contained a color adjective-noun combination…

Nonverbal and other visual cues are well established as a critical component of human communication. Under most circumstances, visual information is available to aid in the comprehension and interpretation of spoken language. Citing these facts, many L2 assessment researchers have studied video-mediated listening tests through score comparisons…

Although superior visual search skills have been repeatedly reported for individuals with autism spectrum disorder, the underlying mechanisms remain controversial. To specify the locus where individuals with autism spectrum disorder excel in visual search, we compared the performance of autism spectrum disorder adults and healthy controls in…

Various tactile methods, such as Braille, have been employed to enhance the recognition ability of chemical structures by individuals with visual disabilities. However, it is unknown whether reading aloud the names of chemical compounds would be effective in this regard. There are no systems currently available using an audio component to assist…

Previous studies have proposed that humans may be born with mechanisms that attend to conspecifics. However, as previous studies have relied on stimuli featuring human adults, it remains unclear whether infants attend only to adult humans or to the entire human species. We found that 1-month-old infants (n = 23) were able to differentiate between…

Testing learners' English proficiency is central to university English classes in Japan. This study developed and implemented a set of parallel online receptive aural and visual vocabulary tests that would predict learners' English proficiency. The tests shared the same target words and choices--the main difference was the presentation of the…

This study aims to examine the developmental changes in young children's perception. A matching completion task consisting of three geometric figures and one bird-like figure were completed by children 3-5 years of age ("N" = 99). The rotation effect, in which the correct response decreased with orientation (45°, 90° 135°, and 180°), was…

It has been repeatedly argued among vocabulary researchers that semantically related words should not be taught simultaneously because they can interfere with each other. However, the question of what types of relatedness cause interference has rarely been examined carefully. In addition, there are disagreements among the past studies that have…
